Online calculation of the number of bricks per house. Calculation of bricks for a house: main methods and features of their application

Every time a construction project is started, you have to calculate the financial costs, regardless of whether you do it yourself, with the help of neighbors or professional builders a house is being built. Significant differences will be in the timing, quality of work performed, but most importantly - in the price of the entire event.

You can reduce risks and get high-quality results by engaging a certified professional contractor. The preliminary cost of building a house can be calculated using an online construction calculator.

Calculation methods for construction work

Calculations can be made in three ways:

1. Measurements based on the design area.
2. Calculations based on built-up area.
3. Determination based on construction volumes.

The first two methods result in an inflated estimate. It includes additional costs for the expected overconsumption of material and an acceptable increase in its cost. The possibility of additional unforeseen costs is taken into account.

The third approach (calculation based on real volumes) is more accurate and objective. He takes into account the work that will be directly carried out. The volume of completion for each construction segment is calculated. Therefore, at the stage of drawing up estimates, the customer has the opportunity, without disturbing the project, to make his wishes for individual structures (for example, for floors, roofing). Deviations from the total cost are possible within 15%.

According to the latter principle, unlike many other resources, a unique mathematical calculator for calculating the construction of a house from the website works.

Calculation algorithms for an online calculator for building a house

The calculation is based on simple mathematics. First, to determine the volume, you need to set the width, length and height (thickness) of a certain structure.

Secondly, take into account building codes and rules that apply to the specific structures chosen for the project.

Thirdly, the current price of the materials used, the tools used, the equipment used, and the labor of specialists is taken into account. It is important that our prices for building materials are stable and there are no sudden jumps. This is possible thanks to the presence of our own warehouse store with materials.

Fourthly, the calculations are based on existing and tested drawings. Therefore, when designing a house on our construction calculator you get a result that is associated with actually implemented projects. The constant practice of contracting work allows us to take into account all, even small, current costs. That is why construction cost calculations using this online calculator are more accurate than those obtained from similar services.

Fifthly, the reliability of the result is ensured by adding up separate calculations for each construction segment:

• laying the foundation;
• construction of walls and ceilings;
• roofing with the installation of a chimney;
• installation of stairs, windows, doors;
• façade design.

In addition, you can use our calculator to calculate the cost of building or repairing individual structures of your home.

Features of the formation of the price of work for different elements of the structure

Foundation

Before starting calculations, you need to decide on the type of its design. The settings of our computer provide the following foundation options:

• strip on stilts;
• tiled monolith;
• monolith with a base;
• with a ground floor.

The design is selected taking into account the mass of the designed structure and the geological features of the soil at the site.

Next, for calculations, you need to indicate the dimensions of the desired building (width, length) and the thickness of the foundation. We get three numbers: the price of the work, the cost of materials, the final cost. This result will appear at every stage.

The scheme is similar. We choose which walls we will build and the height of the floor. We suggest paying attention to:

• cellular concrete blocks;
• walls made of ceramic bricks;
• porous ceramic blocks.

It is worth knowing that the calculator will calculate the construction of a house from blocks to be slightly more expensive than in the case of brickwork. But we advise you to initially choose material based on characteristics, not price.

Floors

The construction of floors is of particular interest due to its ability to combine various options. The online construction calculator offers you to select floors for the basement and floor separately. Also note the difference in design:

• wooden or glued beams;
• concrete plates or monolith.

In your choice, it is important to proceed from general requirements to the structure under construction and financial capabilities. With proper selection of floors, you can even save money. For example, it is better to use concrete between the basement and the first floor. The house will be better protected from moisture coming from below, and the floors will withstand more weight. At the core attic floor you can use wood, less durable concrete, but cheaper. This will also improve thermal insulation.

If you insure yourself as much as possible in terms of fire safety, it is better to contact concrete partitions. However, it is important to consider the possibilities load-bearing structures(foundation, walls) in terms of withstanding significant loads.

Roof and chimney

The difference in their range is only in price and aesthetics. The elements fully perform their functions, regardless of price. pay attention to the following types tiles:

• natural;
• composite;
• bitumen (soft);
• metal.

The latter option is characterized by the greatest prevalence in modern construction. The chimney pipe can be chosen from brick, ceramics or stainless steel.

Ladder

The staircase is one of the elements of the house that cannot be defined by volume. An online calculator for calculating the construction of a house determines the price of stairs based on the material of manufacture and the number of floors. They can be wooden, metal, monolithic (made of reinforced concrete).

Windows, doors

Unique feature The website's house construction calculator takes into account the areas allocated for window and door openings. When you indicate the number of windows and doors, the final price of building a house according to the calculator will be lower due to the reduction in the calculated volumes of materials for the walls.

Exterior finishing needed not only for the exterior, but also for the heat and sound insulation of the building. Online calculator for determining the cost of building a house shows options facade design using:

• clinker tiles;
• facing bricks;
• technologies " wet facade»;
• ordinary plaster.

The latter option is cheaper, but the plaster must be applied to walls whose thickness provides thermal protection.

Using a construction calculator on the site will help you not only imagine the cost of the work, but also develop a preliminary detailed design of a house made of aerated concrete. The accuracy of the calculations is guaranteed by a combination of theoretical calculations with real experience in carrying out many construction projects.

When starting the construction of a house, many do not even approximately understand how to correctly calculate the amount of brick so that there is exactly enough of it, there is no need to buy more, and at the same time, so that there is no leftover. And if the latter can still be dealt with - something can be completed or delivered, then ordering additional material from another batch means violating the general concept of color. Products from different batches may differ not only in shades, but even in texture, which once again confirms the need for mandatory preliminary calculation of bricks for masonry.

What parameters do you need to know?

In order to determine the amount of material for the house, you can use a calculator (see below) or calculate it yourself. To do this you need to know the following initial data:

• the length of the perimeter walls;
• wall area (width x height);
• thickness (half, one, two, two and a half bricks);
• brick size;
• type of mortar joint.

You can go the other way and calculate the consumption by volume, based on the fact that each cube of wall requires 400 ± 1 pcs. Accordingly, the amount of mortar is determined separately for solid bricks, separately for hollow bricks - in this case, the consumption increases by 15% for filling voids.

Let's give an example. For a wall 6 meters long and 3 meters high (area 18 sq.m.) you will need 62 bricks.

To determine bricks for construction, there are tables that provide information on the size of bricks, type and volume of mortar, seams, etc., which allows you to approximately determine required amount. But in this case the error can reach 15-20%.

How can you properly distribute load bearing- external and interior walls they go in one brick, there is a distance between them

If you don't use a brick per house calculator, you'll have to take a lot of data into account. It’s easier and, as practice shows, cheaper to contact specialists or use online services.

Brick calculator

Wall thickness

The first condition of warm and comfortable home- adequate climatic zone and region wall thickness. Standard products 25x12x65 cm can be laid in several ways, which will determine its thickness:

• half - 12 cm;
• in one - 25 cm;
• one and a half - 38 cm;
• in two - 51 cm;
• at two and a half - 64 cm.

For the vast majority of the territory, excluding the Krasnodar Territory and Crimea, the optimal thickness is 51-64 cm, respectively, 2 or 2.5 bricks.

Now, after determining the thickness, you can proceed to calculating the perimeter, for which you need to know how tall the house is planned and what the length of the walls will be. After obtaining this value, you need to subtract the area of ​​the door and window openings. The final balance will be the required area of ​​future brick walls.

Block sizes

This key parameter, affecting total material. Depending on the type, the following varieties are distinguished:

• single - 25x12x6.5 cm;
• one and a half - 25x12x8.8 cm;
• double - 25x12x13.8 cm.

The first option looks much more aesthetically pleasing and neat, although this type of installation takes the most time. One-and-a-half and double ones are installed much faster (even according to the most conservative estimates, you can save almost 2 times), but the finished structure does not look so impressive.

When determining how many bricks are needed to build a house, take into account the height masonry joint. When laying a single joint, the height of the seam is 5 mm, double and one and a half – almost a centimeter.

The table below shows an example of the most commonly used building materials (single, one-and-a-half, double), taking into account the height of the masonry joint and without it. Using these data, you can also determine the amount of material for the construction of any building, for which you multiply the data by the area of ​​the wall.

In any batch there is a defect - split, knocked down or cracked specimens. This may be the result of improper storage or transportation. On average, 5-7% is spent on defects; accordingly, possible defects are added to the original number and ordered as much as required.

Facing

Novice builders are no less interested in the number of bricks in the masonry for wall cladding. Here the calculation algorithm is the same, but the process will take half a brick. In order to understand exactly how much material is needed, you need to know two sources:

• brick dimensions;
• seam height.

If a standard single 25x12x6.5 cm is used, then about 52 pieces will be needed per square of surface with a seam height of 10 mm.

Amount of solution

To determine the budget, you need to know how much solution is needed, or rather the volume of its components (sand, cement, water and additives).

The amount of solution is determined according to standard parameters:

• for full-bodied buildings in one row - 3 masonry blocks of 0.22 cubic meters per 1 m. ready-made composition;
• for hollow in one row - per 1 m 3 masonry 0.24 cubic meters. ready-made composition;
• for full-bodied in two rows - per 1 m 3 masonry 0.25 cubic meters. ready-made composition.

Hollow ones require more solution, since part of it is spent filling the voids.

The number of components and the mixing procedure per 1 m 3 of masonry are indicated in detail in the article. Here we add that the service life and thermal insulation of the walls directly depend on the consistency. Too liquid will lead to the formation of a large number of cold bridges and the formation of condensation with subsequent destruction of the masonry. Too thick - it will not provide the necessary adhesion and will also begin to burst gradually.

Observe the parameters and proportions of cement, sand and water when mixing the mortar so that you do not have to redo it.

VIDEO: detailed instructions determining the quantity

An example of calculating the amount of bricks for building a house of 120 sq.m:

1. Determining the thickness of the walls of the future house

Since we take the central strip of Russia as a basis, the thickness will accordingly be 2 stones. We take the standard size - single 25x12x6.5 cm.

1. We calculate the perimeter of the walls and area

Length - 10 and 12 meters, 4 walls. The perimeter is 44 meters. Height is standard 3 meters. The area is 132 sq.m.

1. Using the table above, we determine the type of masonry (double) and type (single)

It turns out, taking into account the seam, 204 pieces. We multiply the area by the quantity 132 sq.m. x 204 pcs. = 26928 pieces.

1. Taking marriage into account

On average, 7% is rejected, which is 2000 pieces.

Total, for a house with an area of ​​120 sq.m. with a wall height of 3 meters you will need 28928 single bricks.

Using a similar formula, they determine how much is needed for a 10x10 m house. Without repeating the calculation algorithm, we will immediately present the result. On standard house with a wall height of 3 meters, 24,480 bricks will be needed for construction and 6,120 pcs. on the cladding.

Calculation example for cladding

1. Wall area (12 x 2 + 10 x 2) x 3 = 132 sq.m
2. It takes an average of 51 pieces to cover 1 square, respectively, 132 x 51 = 6732 pieces.
3. Taking into account 7% defects, you will need 7203 bricks.

Before you begin directly calculating the amount of material, calculate the area of ​​the window and doorways and subtract from the total area of ​​the walls.

VIDEO: In what cases can it be used? brickwork 25 cm thick, one stone

When calculating the amount of bricks, it is important to take into account that approximately 5% of the material will need to be written off as damage or possible defects associated with transportation. Therefore, we recommend that you immediately include this in the estimate and buy with a reserve, since different batches may differ slightly, but still differ in appearance and other parameters.

Fence calculator

Calculating the fence will require deciding on its width and height. The following standards must be taken into account: when laying 1 brick, 52 pieces of brick are required per 1 square meter; when laying double bricks, 104 pieces are required, respectively.

1. Pillar. The size of a standard brick is 250*120*65. To lay 1 row of a supporting structure 380*380 mm, we need 4 bricks. Dividing the height of the pillar by the height of the brick, we get a piece quantity required material.
2. Flights. Their calculation depends on the type of masonry used. Most often, single brick masonry is used. We multiply the area of ​​one section by 52 and get the required amount of bricks.

How many bricks per square meter when building a house?

Before calculating the amount of brick that will be needed to build the wall of a house, you need to decide on the thickness of the future walls. Using the example of standard BARRUM brick, size 250*120*65 mm. You can lay it in one brick, then the thickness of the wall will be 250 mm, two bricks - 510 mm, half a brick - 120 mm, one and a half bricks - 380 mm and, accordingly, the width of the wall laid out in two and a half bricks will be equal to 640 mm.

We find the area of ​​all window and door openings and subtract them from the total area and get the area of ​​the brick wall.

Considering standard height a seam equal to 10 mm, to lay a wall with an area of ​​1 square meter in two bricks, you will need 204 bricks, in two and a half - 255 bricks.

Knowing the consumption of bricks per 1 square meter, you can calculate how much material will be required for construction. To do this, multiply the norm by the area of ​​the brick wall.

Building brick is one of the most popular building materials in our country for the construction of residential buildings and other buildings. for various purposes. Before starting the construction of any brick building, it is necessary to purchase the required amount of bricks, for which a preliminary calculation must be made. Correctly carried out calculations will allow you to avoid extra expenses for the purchase of excess building materials and avoid problems with their shortage during construction.

Before you start making calculations, you need to determine:

• type of brick used;
• method of laying bricks, depending on required thickness house walls;
• total area walls of the house (external and internal);
• the total area of ​​all window and door openings in all walls of the house.

At the beginning of work, it is necessary to calculate the load on the foundation.

Main types of bricks and laying methods

Standard bricks produced today by various manufacturers have the same dimensions in length and width (25x12cm) and differ in thickness by:

• Single (0.65cm).
• One and a half (0.88 cm).
• Double (1.38cm).

Walls made of single bricks look the most aesthetically pleasing. However, the use of one-and-a-half or double-thick bricks can greatly speed up and simplify the construction process. At the same time, the consumption of masonry mortar used is also significantly saved.

The thickness of the walls of the house depends on the methods of laying bricks. They can be:

• half a brick (wall thickness 12cm);
• 1 brick (wall thickness 25cm);
• 1.5 bricks (wall thickness 38cm);
• 2 bricks (wall thickness 51cm);
• 2.5 bricks (wall thickness 64cm);

In the Russian climate, the most optimal wall thickness is 2 or 2.5 bricks.

Calculation of the required amount of bricks

Calculation of the amount of bricks can be carried out in two main ways:

• Does not take into account the thickness of the mortar joint.
• Taking into account the thickness of the seam, which is usually from 5 to 10mm.

It should be borne in mind that when using the first method, there may be an excess of building materials by 25-30%. The second method is more economical, but it is necessary to add 10-15% to the calculated value to take into account possible brick breakage during construction.

For clarity, let’s calculate for specific example: It is necessary to build a one-story brick house 8 by 10m, wall height 3m and without internal brick walls. There is one opening in the external walls for front door 1 by 2m and three openings for windows 1.2 by 1.5m. The thickness of the walls is two bricks from a standard single brick with a joint thickness of 5mm.

The calculation procedure for the first method will be as follows:

1. We determine the perimeter of the external walls: (8+10)*2=36m.
2. We determine the total area of ​​the walls of the house: 36*3=108 sq.m.
3. We determine the total area of ​​door and window openings: (1*2)+(1.2*1.5)*3=7.4 sq.m.
4. We calculate the area of ​​the brickwork of the walls: 108-7.4 = 100.6 sq.m.
5. Determine the number of bricks in one square meter, for which we calculate the end area of ​​one brick: 0.12*0.065=0.0078 and divide this value by one: 1/0.0078=128, after which we multiply by two (since the masonry will be 2 bricks). We get 128*2=256 bricks per 1 sq.m.
6. We calculate the required number of bricks for building a house by multiplying the total area of ​​the walls without taking into account openings by the number of bricks in 1 sq.m: 100.6*56=25753.6.

Thus, 25,754 bricks will be needed to build the walls of the house.

Carrying out the calculation using the second method, to determine the amount of brick in 1 sq.m, we add 5 mm to the standard brick dimensions (joint thickness): (0.12+0.005)*(0.065+0.005)=0.00875. Accordingly, the amount of brick in 1 sq.m will be: 1/0.00875*2=229 bricks. Multiplying this number by the total area of ​​the masonry we get: 229*100.6=23037.4. Let's add to this value about 1500-2000 bricks per battle and we get the amount of bricks needed to build a house: approximately 24,500-25,000 bricks.

From the above example it can be seen that the second calculation method is more economical.

The calculation for other wall thicknesses is carried out similarly, taking into account the appropriate corrections. If you need calculate the number of foam blocks per house - see this article.

Using online calculators for calculations

If you don’t want to do mathematical calculations, then to quickly calculate the required amount of bricks to build a house, you can use a free online calculator.

By entering the parameters of your future home into the appropriate fields, you can instantly get the desired result. In addition to calculating the required amount of bricks, many online calculators allow you to simultaneously calculate other useful parameters, for example, the required amount of mortar for laying walls.

chas-remonta.com

The construction of various structures using brickwork requires determining the exact amount of material to complete the work.

To carry out such calculations, special online calculators are used, widely available on the Internet, on sites engaged in the trade of building materials. By doing construction work it is necessary to strictly follow the norms and rules to ensure the further safe and long-term operation of the objects being built, therefore the parameters of the brickwork are calculated based on the purpose of the structure and environmental conditions.

In addition, bricks from different manufacturers may vary slightly in size and in their properties, which makes it difficult to quickly select the required amount of materials for construction.

The calculator for calculating bricks allows you not only to make calculations for the construction of ordinary walls, but also to make adjustments to the estimate according to the type of masonry (from 0.5 to 2.5 bricks with dressing), the size of the object being built, the brick manufacturer and the type of mortar used. The calculations take into account the implementation of various openings for installing windows and doors with full consideration of their future length and width.

The calculator interface is very clear and does not require additional calculations. It is enough to enter the basic geometric parameters of the future building to start calculations automatically. As a result, the consumer receives accurate data on the required number of bricks in pieces, the volume of brickwork in cubic meters, as well as the consumption of mortar during operation.

General information on the calculation results

• Building perimeter

The total length of all walls taken into account in the calculations.

• Total masonry area

Square outside walls Corresponds to the area necessary insulation, if such is provided for in the project.

• Wall thickness

The thickness of the finished wall, taking into account the thickness of the mortar joint. May differ slightly from the final result depending on the type of masonry.

• Quantity

The total number of bricks required to build walls according to given parameters

• Total material weight

Weight of bricks excluding mortar and masonry mesh. Just like the total volume, it is necessary to select a delivery option.

• Quantity of mortar for the entire masonry



Volume mortar, necessary for laying all the bricks. The volumetric weight of the solution may differ depending on the ratio of components and additives introduced.

• Number of flexible links

Necessary for attaching the facing layer to the main load-bearing walls. The length of the flexible connections depends on the total thickness of the wall, taking into account the insulation.

• Number of rows in masonry including seams

Depends on the height of the walls, the size of the material used and the thickness of the masonry mortar. Excluding gables.

• Quantity of masonry mesh

Required amount of masonry mesh in meters. It is used to reinforce masonry, increasing the solidity and overall strength of the structure. Pay attention to the number of reinforced rows; by default, the reinforcement of every third row is indicated.

• Approximate weight finished walls

The weight of the finished walls including all bricks, mortar and masonry mesh, but excluding the weight of insulation and cladding.

Load without taking into account the weight of the roof and ceilings. This parameter is necessary to select the strength characteristics of the foundation.

To calculate the material for partitions, you need to start a new calculation and indicate the length of only all partitions, the thickness of the walls to the floor of the brick, as well as other necessary parameters.

Features of brick consumption on the wall

When it comes to brick construction, it is necessary to take into account not only the size of the blocks themselves, as well as the total area and thickness of the walls being built, but also the features of the masonry. The following parameters play a role:

• masonry width (from 0.5 to 2.5 bricks);
• thickness of the mortar joint between the blocks (from 0.5 mm);
• the number and location of door and window openings in the room.

It is worth taking into account the fact that even when purchasing bricks of a strictly “reference” size of 250x120x65 mm, you cannot be sure that the mortar joint between all blocks will be the same. Firstly, each batch of building materials may contain defects. Secondly, some bricks may be damaged during transportation. One way or another, the difference in size will have to be compensated by the thickness of the mortar joint. As a result, the pre-calculated amount building material will be significantly different from what will happen in practice.

This picture can be avoided, firstly, by taking into account in advance the percentage of possible brick defects (5-8%; in some online calculators this parameter is enabled by default). Secondly, everything made using special tools To be on the safe side, the calculations should be duplicated independently, guided by the algorithm proposed below.

Calculation of the number of bricks per wall - table!

• Width of external and interior walls buildings will differ significantly. The difference between load-bearing walls and simple partitions will be no less noticeable.
• The total area of ​​the building's door and window openings will not be taken into account in the calculations.

To better understand the principles of this rather complex brick calculation, let’s look at the calculations using a specific example. Let's assume that the object we are planning has the following characteristics:

• It is planned to lay out the internal load-bearing walls with a thickness of 1.5 one-and-a-half bricks. Their total length is 22 m.
• The number of interior doorways is 4. Their dimensions are 1.25 m x 2.1 m.
• The partitions are planned to be laid out with a thickness of 0.5. Their total length is 26 m.
• The planned thickness of the external walls is 2 double.
• The number of external doorways is 2 (1.3 x 2.15 m). Window – 7 (1.4 x 1.85 m).

Taking this data into account, in practice our calculation will look like this:

• (2 x 15 x 3) + (2 x 8 x 3) – (7 x 1.4 x 1.85) = 119.86 m² - area of ​​the external walls;
• (22 x 3) – 4(1.25 x 2.1) = 55.5 m² - area of ​​internal walls;
• (26x3) = 78 m² - area of ​​partitions.

Using reference materials from the Internet, we learn that:

• for 1 m² of masonry in 2 doubles, 104 pieces will be required;
• for 1 m² of masonry of 1.5 one and a half square meters, 78 pieces will be required;
• for 1 m² of masonry with 0.5 standard single bricks, 51 pieces will be required.

Therefore, in total (taking into account combat and marriage) we will need to purchase:

• 1.08 x (119.86 x 104) = 13463 doubles;
• 1.08 x (55.5 x 78) = 4675 one-and-a-half pieces;
• 1.08 x (78 x 51) = 4296 standard pieces.

Not like that in a complicated way you can make the necessary calculation of the building material.

Brick calculator

To avoid interruption of the construction process due to a shortage of bricks and unwanted expenditure of funds on the delivery of purchased building materials, it is better to deliver everything at once. Excess material will significantly increase the cost of construction. Therefore, if you need to calculate bricks for masonry, the online calculator on the construction site is the best modern tool for accurate calculations.

The principle of determining brick consumption based on the volume of walls

The methodology is based on determining the quotient of dividing the total volume of walls (adjusted to take into account the deduction of openings for windows and doors) by the volume of one brick. The result is the required quantity in pieces for brickwork.

In practice, the problem is solved through several stages:

• determination of the areas of internal walls and partitions, external load-bearing walls, differing in thickness;
• calculation of the areas of window and door openings;
• subtracting the size of openings from the wall area;
• calculating wall volumes by multiplying their adjusted area by thickness;
• calculation of bricks for laying external, internal walls and partitions by dividing the resulting wall volumes by the volume of one brick.

The task is complicated by the fact that there are seams between the bricks that are filled with mortar. Their standard thickness is taken to be 10 mm, but it can be less if the brick has an ideal geometry. A few millimeters of mortar between bricks on the scale of the entire building grows into a rather impressive value, reducing brick consumption.

A simplified calculation is based on the standard dimensions of a single brick of “normal shape” (1NF) - 250 x 120 x 65 mm (length, width, height). In a cubic meter of masonry, exactly 512.82 pieces of such bricks fit. Taking into account the seams (10 mm), the difference will be 118 bricks, which for the entire facility represents a mountain of unnecessary material. Using an online calculator, the purchase of excess building materials will be eliminated.

Any batch of bricks initially has a certain percentage of defects. Losses are inevitable during loading, transportation and unloading. This damage increases the calculated amount by 5 – 8%.

An example of calculating the required number of bricks per unit area

Design solution one-story house(ceiling height - 3 m) assumes a rectangular outline with a length of 15 meters and a width of 8 meters. The initial data are also:

• length of internal load-bearing walls – 22 m;
• length of partitions – 26 m;
• number of doors in external walls – 2 pcs. (size 1.3 x 2.15 m);
• number of doorways in internal walls – 4 pcs. (size 1.25 x 2.1 m);
• number of windows – 7 (opening size 1.4 x 1.85 m);
• type of masonry of external walls - 2 bricks (double);
• internal load-bearing walls are designed to be 1.5 bricks (0.38 m);
• The thickness of the partitions is 0.5 bricks (0.12 m).

The calculations boil down to determining:

• 1.Adjusted area of ​​masonry of external walls (without openings):
• S= ((2 x 15 x 3) + (2 x 8 x 3) – (7 x 1.4 x 1.85)) = ((90 + 48) – 18.13) = 119.86 m².
• 2.Areas of internal walls:
• V int.st. = ((22 x 3) – 4(1.25 x 2.1)) = 55.5 m².
• 3. Areas of partitions:
• V lane = (26x3) = 78 m².

Using a reference table, the value of how many bricks are in 1 m2 of masonry is determined:

Based on the fact that for a unit of masonry area of ​​2 bricks (using double bricks) 104 pieces are needed, then the external walls of the entire building must:

119.86 x 104 = 12466 pcs. double bricks.

For internal load-bearing walls of 1.5 bricks (one-and-a-half bricks) you need: 78 x 55.5 = 4329 pieces, where 78 is the average value showing how many one-and-a-half bricks are in 1 m2 of masonry with a thickness of 0.38 m.

For partitions of 0.5 bricks of material you will need: 78 x 51 = 3978 pieces of single brick.

That. single bricks need to be purchased 3978 x 1.08 = 4296 pieces, one-and-a-half - 4329 x 1.08 = 4675 pieces, and double bricks - 12466 x 1.08 = 13463 pieces - taking into account 8% waste from breakage and scrap.

Types and sizes of bricks

The start of construction is preceded by the calculation and purchase of the required building materials. A correctly carried out calculation will prevent a shortage of material during construction or its excess during construction. large quantities. Experts recommend purchasing bricks one-time to avoid color discrepancies. To calculate the amount of material, you will need the following information:

• type of bricks used;
• masonry method, determined based on the optimal thickness of the walls of the future housing;
• area is calculated separately internal partitions and external walls of housing;
• The dimensions of future windows and doors are taken into account.

Depending on the purpose of the building and in what climatic conditions it will be located, the type of brick is chosen. Based on the material of manufacture, it is classified into the following types:

• Adobe products consist of clay and various fillers.
• Most common ceramic material from baked clay.
• Sand-lime brick contains sand and lime.
• The hyper-pressed material includes lime and cement.
• Clinker bricks are produced from special baked clay.
• Fireclay is the source of fireclay bricks.

Depending on the purpose of use, brick can be:

• Construction (private). Suitable for arranging interior and exterior walls of buildings. Considering its unattractive appearance and the likelihood of minor chips, when used externally, the walls of the future home are subject to insulation and protective finishing. External condition the product does not reduce its strength.
• The facing (facade, front) material is characterized by an ideal surface and the absence of defects. In the role facing material ceramic, silicate and hyperpressed products can be used. The maximum deviations in dimensions according to GOST are 2, 3 and 4 cm in height, width and length, respectively.

In places high humidity(lowlands or natural areas with a cold climate), ceramic material is optimal due to its low hygroscopicity. From option sand-lime brick in this case it is better to refuse due to its hydrophobic properties. The most suitable operating conditions for silicate material are dry and hot latitudes. Facing brick, in turn, is divided into textured and façade materials.

Depending on the filling, bricks are divided into solid and hollow.

Size of all bricks produced by different manufacturers, has established standards: the width and length of the product do not change and are 120 and 250 mm, respectively, the thickness is available in 3 options:

• single - 65 mm;
• one and a half - 88 mm;
• double - 138 mm.

From an aesthetic point of view, single brick masonry is the most attractive. One-and-a-half and double thickness of the product helps simplify and speed up the housing construction process. In addition to this, there is a significant saving in the solution consumed.

Masonry methods

To calculate the amount of material required, the method of laying is of paramount importance. The main types of solid masonry are represented by the following options:

• The thickness of a half-brick wall is 12 cm. This method is used exclusively for internal partitions.
• A wall of 1 brick has a thickness of 38 cm.
• 51 cm - standard wall of 2 bricks;
• The wall thickness of 64 cm indicates a masonry of 2.5 bricks.

The walls of a home are subject to loads in three directions: compression, lateral rotation or displacement. In the first case, vertical forces from structures located above tend to flatten the wall. In low-rise private houses these loads are small and side surfaces have a sufficient margin of strength against compression. Rotational and horizontal forces occur as a result of soil pressure on the basement wall or increased cross winds. Such loads tend to displace a section of the wall from its occupied position. Housing with thin walls is at risk of cracking or even breaking. To ensure a margin of resistance to displacement forces, the increased thickness of the outer side surfaces is included in the design calculations. Considering climatic features Russian regions, the most acceptable is considered to be a laying of 2 or 2.5 bricks.

Calculation method

There are two main options for determining the amount of brick needed for housing construction:

• the thickness of the connecting seams is not taken into account;
• taking into account the size of the mortar joint, which ranges from 5 to 10 mm.

Calculation according to the first option usually leads to the formation of excess building materials. The second option is more economical, however, 10-15% is added to the result obtained in case of possible losses during construction.

We give the calculation procedure using an example with specific data:

• it is planned to build a 1-story brick house 9x10 m, 3 m high;
• laying of external walls in 2 bricks, 1 door 1x2 m and 4 windows 1.2x1.5 m are provided;
• a single brick is used, the thickness of the mortar joint on the outer side surfaces and partitions is 7 mm;
• internal partitions made of half a brick, two 10 m long, one 9 m long;
• partitions have 5 doors 1x2 m;

First of all, the amount of material for the outer side structures is determined. The calculation algorithm includes the following steps:

• Perimeter of load-bearing walls: (9+10)x2=38 m.
• Total area of ​​external side structures: 38x3=114 m2.
• Total area of ​​window openings and doors: 4x(1.2x1.5)+1x2=9.2 m2.
• Net masonry area of ​​external walls: 114-9.2=104.8 m2.
• To calculate the amount of building material in 1 m2, we determine the area of ​​the end part of one product: 0.12x0.065 = 0.0078 m2, respectively, in 1 m2 there will be 1/0.0078 = 128 products. Taking into account the laying method, the value doubles and the result is 256 pieces per 1 m2.
• For the construction of load-bearing side surfaces you will need: 104.8x256 = 26829 copies of the product.

The amount of material for internal partitions is calculated in a similar way:

• total area internal structures: 2x(10x3)+9x3=87 m2.
• Square internal doors: 5x1x2=10 m2.
• Net area of ​​partitions: 87-10=77 m2.
• Area of ​​1 product (spoon part): 0.25x0.065=0.01625 m2.
• Quantity per 1 m2: 1/0.01625=61.5 pieces.
• For all partitions: 77x33.3=4736 pieces.

We determine the total amount of material for external and internal walls: 26829+4736=31565 pieces.

In the second option, when calculating the area of ​​the brick, we add the size of the mortar joint:

• For external walls: (0.12+0.007)x(0.065+0.007)=0.00914
• Quantity per 1 m2: 1/0.00914=109.4 pcs., taking into account the laying of 2 bricks: 109.4x2=219 pcs.
• Total quantity for external walls: 104.8x219=22951 pieces.
• Area of ​​the tray part of the brick for internal partitions: (0.25+0.007)x(0.065+0.007)=0.0185 m2.
• Quantity per 1 m2: 1/0.0185=54 pieces.
• Total quantity for internal partitions: 77x54=4158 pieces.
• Total for external and internal walls: 22951+4158=27109 pieces.

The results of calculating the total area of ​​the external side surfaces allow you to purchase insulation, if it is provided for in the project. If you don’t want to make calculations on the amount of brick required yourself, an online calculator will come to the rescue.

When starting to build their own home, many people do not know how to calculate the number of bricks per house in order to avoid overuse of material or be left without it in the midst of construction.

The calculation must be made in such a way that it is possible to purchase material from one batch at once. In this case, there will be no need to purchase additional bricks in the future. The fact is that products from different batches may differ in color, which will negatively affect appearance building. For this you need an accurate calculation of the bricks for the house.

Wall thickness in calculations

To accurately calculate the amount of bricks per house, you need to determine the required wall thickness. Products with a standard size of 250x120x65 mm can be laid in half, one and a half, two and two and a half bricks, and the wall thickness will be:

• half a brick – 120 mm;
• in one brick - 250 mm;
• one and a half bricks - 380 mm;
• in two bricks - 510 mm;
• two and a half bricks - 640 mm.

Building a house in domestic conditions involves optimal thickness walls of two and two and a half bricks.

After the thickness of the building walls has been determined, the basic parameters of the structure should be established. To do this, you need to clarify the perimeter and height data. The product of these indicators will allow you to find out the total area of ​​the walls. To more accurately calculate how many bricks will be needed for a house, the total area of ​​door and window openings should be subtracted from the resulting number. The result will be the area of ​​the brick wall.

Brick sizes

The dimensions of the product have a direct impact on how much brick is needed to build a house. There are several types of products that differ in size:

(function(w, d, n, s, t) ( w[n] = w[n] || ; w[n].push(function() ( Ya.Context.AdvManager.render(( blockId: "R-A -388243-8", renderTo: "yandex_rtb_R-A-388243-8", async: true )); )); t = d.getElementsByTagName("script"); s = d.createElement("script"); s .type = "text/javascript"; s.src = "//an.yandex.ru/system/context.js"; s.async = true; t.parentNode.insertBefore(s, t); ))(this , this.document, "yandexContextAsyncCallbacks");

• single: length – 250 mm, width – 120 mm, height – 65;
• one and a half – 250 x 120 x 88 mm;
• double – 250 x 120 x 138 mm.

The purchase of one-and-a-half or double bricks will significantly affect the speed of construction work, increasing it. But this can have an adverse effect on the overall aesthetics of the building. Single brick walls look more impressive and neat. Everyone chooses the size of the material used independently.

When calculating how many bricks are needed for a house, do not forget about the number of mortar joints that have a certain height. When laying two or two and a half bricks, the seam will have a height of 10 mm.

The table below will help you correctly calculate the required amount of bricks for the construction of any structure. The data was calculated based on domestic standards for artificial building materials.

The necessary data from the table must be multiplied by the pre-calculated area of ​​the brick surface. The result will be the amount of brick needed for construction. We should not forget about defective products, which are found in almost every batch. When buying a brick, you should add about 7% of the amount of material received. total number bricks.

Brick for cladding

No less often the question arises of how to calculate the bricks for a house, which are needed not for construction, but for cladding. In this case, the consumption will correspond to the consumption of the general masonry, only half a brick. To do this, you need to know two sizes: jointing (seam) and brick. For example: laying a brick standard size, with a length of 250 mm and a height of 65 mm, the width of the jointing is 10 mm. When calculating, it turns out that with the given indicators per 1 sq. per meter of surface you need to use 50-52 products.

Amount of solution

When calculating bricks, it is advisable to know the amount of mortar needed to build a house. The consumption of the composition can be determined as follows:

• for one cubic meter of masonry, 0.21 cubic meters is required. meter of solution;
• the wall is laid in two bricks, then the amount of mortar is per cubic meter will be 0.24 cubic meters. meters.

In construction, hollow stone is often used, the voids of which must be filled with mortar, which significantly increases the amount concrete mixture consumed per cubic meter of masonry. Therefore, the standard value is 0.23 cc. meters.

(function(w, d, n, s, t) ( w[n] = w[n] || ; w[n].push(function() ( Ya.Context.AdvManager.render(( blockId: "R-A -388243-7", renderTo: "yandex_rtb_R-A-388243-7", async: true )); )); t = d.getElementsByTagName("script"); s = d.createElement("script"); s .type = "text/javascript"; s.src = "//an.yandex.ru/system/context.js"; s.async = true; t.parentNode.insertBefore(s, t); ))(this , this.document, "yandexContextAsyncCallbacks");

It is important to know! The consumption of materials directly depends on the density of the solution. Concrete is diluted, as a rule, in the following proportion: 1.2 t quartz sand, 0.3 t of M400 cement and water. If the solution is too liquid, it will adversely affect the thickness of the seam, significantly reducing it. This cannot be allowed. Also, a solution that is too thick, which does not contribute to high-quality adhesion of the material. Any deviations in the parameters of the seam can lead to rapid destruction of the building.

Liquid or thick solution leads to the formation of cold bridges, condensation and wetting of the wall. In this case it will not help additional insulation, nor a layer of waterproofing. Therefore, it is very important to observe the required proportions of the solution and accurately calculate the volume required for construction.

Video tutorial on calculating bricks:

An example of calculating the amount of bricks for building a house of 100 square meters. m

For example, before counting the bricks for a house measuring 10 by 10 m, you need to decide how thick the walls will be. A house whose walls will be laid with two stones will require almost twice as much material as with one brick. It is also better to choose the size of the brick in advance.

Calculating the amount of bricks for building a house is carried out in several simple steps:

• calculate the perimeter: 10x4=40 m;
• we find the area of ​​the external walls, for this you need to know the height of the ceilings, which is usually 3 m: 40x3 = 120 sq. m;
• we select the type of masonry and brick: from the table it can be seen that the consumption of a single brick in a double masonry per 1 cubic meter, taking into account the seams, is 204 stones, then, following the calculation formula: 120x204 = 24480 pieces.

That is, to build a house of 100 sq. m you need to purchase 24,480 bricks. Similarly, you can calculate the cladding of a building made in half a brick: 120 x 51 = 6120 facing bricks.

Using the instructions above you can perform the calculation brick house any area: 8 by 10, 10 by 12. Changes will be made in calculating the perimeter of the building. For example, for a house of 80 sq. m:

• we find the perimeter of the walls: 2x8+2x10=36 m;
• We calculate the area with a ceiling height of 3 m: 36x3 = 108 sq. m;
• we find the amount of brick needed to build a house 8 8 by 10: 108x204 (single brick, two stones) = 22032 pieces.

A few important aspects

Also, in each house there is a certain number of partitions and internal walls. No building is complete without a device ventilation system. Therefore, when calculating the amount of material, it is necessary to calculate the total area of ​​the internal walls and partitions, multiply the result obtained by the consumption of bricks per square meter of masonry. It is important to remember that the thickness of internal structures differs significantly from the thickness of external walls.

Poking the front part of the masonry with internal part, requires much more brick consumption.
