Calculation of flooring material board. Beam calculator - calculation for different types of structures

To perform an accurate calculation of floor boards, a calculator created as online service, has been around for many years. With its help, you can calculate the amount of material that will be needed for the construction of logs and flooring.

The calculator is used to determine the volume of not only the floorboard, but also the material for the subfloor. As with the construction of other structures, work on creating high-quality floors requires determining the exact amount of fasteners and insulation, end and other parts.

Features of the online calculator

You need to enter several parameters of the living space into the calculator

Floor calculations using an online calculator are based on dimensions indicated in millimeters. To perform all operations you will need to clarify:

• floor length and width;
• length and thickness of the logs;
• width and thickness of boards;
• house parameters (width).

For each quantity there are certain designations, among which there are numbers and letters that reflect:

• thickness and width of rough subfloor boards;
• the number of jumpers between the lags and the step between them;
• distance between boards.

You can find out exactly how many boards you need for the floor by using one of the offered floor calculator programs. You will need competent, high-quality drawings, in accordance with which the flooring is constructed and the ceiling is arranged.

When starting to select a material, it is necessary to take into account the characteristics of their parameters. The most popular are boards whose thickness reaches 4 cm.

Despite the fact that many designers recommend using products whose this parameter is much higher, boards no thicker than 2 cm are often sufficient.

They are more flexible and durable, and thanks to the high-quality and competent processing of the boards, they are characterized by increased resistance to moisture and temperature changes.

Correctly carried out calculations will allow you to lay a strong screed

It is these qualities that allow properly prepared materials to retain their original shape and avoid cracking, swelling and other damage and deformation.

When do you need a calculator?

The program will even help you determine optimal distance between the joists

Other data may also be required; specifying them will help the calculator determine the exact area of ​​the room and select the most suitable parameters among the many existing proposals. wood materials, the program is able to correctly set the optimal distance between the lags and the components of the structure.

Using the program, the consumer receives specific data on the required quantity of not only lumber, but also insulation required for arranging and creating insulation under wooden flooring. Read more about construction calculators watch in this video:

Another feature of the program is the ability to indicate some options for the layout of the future floor, allowing you to save money and use it when carrying out construction work minimal amount wood and insulation.

To work with online calculator, there is no need to contact specialists and designers. It is enough to use the Internet services, indicating the requested data.

How to calculate the number of boards for the floor

Floor board, how to calculate the quantity

There are no particular difficulties in calculation required quantity floor boards, however, even in such simple calculations there are small nuances.

Calculation of floor area

1. First, it is necessary to conditionally divide the entire floor area into equal rectangles.

Having decided to purchase a floor board, you must first calculate the order volume.

A lot depends on this; the boards must be from the same batch.

Usually proceed as follows:

• – conventionally take one room as a rectangle,
• also take the corridor as a rectangle
• etc.

If the room is not rectangular, then you can roughly divide it into rectangles.

Then measure the area of ​​each rectangle, having measured before:

By multiplying the length with the width, we get the area (S), which is known to be measured in square meters (m2).

2. Secondly, it is necessary to convert millimeters and centimeters to meters.

• Recall that 1 m = 100 cm = 1000 mm.

And now let’s talk about calculating the floor area and, accordingly, the number of boards per floor.

Let's start by calculating the area of ​​the floorboard of one of the rooms:

• It is calculated by the formula S=a h, where S is area, a is width, h is length.

For example, a room 7 meters by 5 meters is calculated as follows: S=a h=7 5=35 m2

If you have several rectangles, then you need to act in the same way as described above when finding the areas of rectangles, then add the resulting area values ​​and find the final area.

S= a1 h1+ a2 h2+ a3 h3,:

• where S – total area,
• a1, a2, a3 – widths of the 1st, 2nd, 3rd rectangles,
• h1, h2, h3 – lengths of the 1st, 2nd, 3rd rectangles.

• So, for example, the total area of ​​three rooms (1st – 3 m by 4 m; 2nd – 5 m by 4 m; 3rd – 7 m by 6 m)
• S= a1 h1+ a2 h2+ a3 h3=3 4+5 4+7 6= 12+20+42=74 m2

Calculation of the number of linear meters of floor boards

As for the calculation of linear meters or a certain number of boards.

We calculate the total area of ​​the order as described above.

Linear meters have:

• width (W)
• and length (D).
• S= a h= linear meters board width.

Order cost = S cost of m2 floor boards.

For example, we need 40 linear meters of floorboards, the width of which is 100 mm and the thickness of 35 mm.

• We convert millimeters into meters 100 mm = 0.1 m, we find that S of the order is equal to the product of linear meters and the width of the board, that is, S = 40 0.1 = 4 m2
• Price 1 m2 = 85 UAH/m2, Order cost = S order Cost = 4 85 = 340 UAH.

If the number of boards with a known length and width of the board is known, then the calculations are similar and are performed according to the formula:

• Order S = number of boards board length board width.

If you know the total area of ​​the order and you need to calculate the number of boards, then you can use the formulas:

• Linear meters = order S / board width,
• Number of boards = linear meters / board length.

• Order quantity = S order board thickness (in meters).

Edged boards are in greatest demand in the lumber market. Their distinctive feature- four-sided processing and removal of edges with tree bark. High demand for this type building materials are explained by practicality, durability, environmental friendliness and ease of use.

The main areas of application of edged boards are construction and furniture production. In construction this material can be used for laying floors, ceilings, erecting walls and stairs. IN furniture production boards are used to create solid wood furniture.

Calculation

• Calculate the surface area that needs to be covered (for example, 10*10=100 m²);
• Calculate the area of ​​one board (for example, with board parameters of 20cm*5cm*2000 cm, the area of ​​one board will be equal to 0.2m*2m=0.4m²);
• Divide the surface area by the area of ​​one board (100 m²/0.4 m²=250 pieces).

To calculate the number of boards when purchasing in cubes, you must:

• Calculate the required number of boards (divide the surface area by the area of ​​one board);
• Calculate the required cubic capacity by multiplying the parameters of the board by the required quantity (for example, you need 20 pieces of boards with a parameter of 20 cm * 5 cm * 2000 cm, which means the required volume is 20 * 0.2 * 0.05 * 2 = 0.4 m³). In this case, all values ​​must be converted from centimeters to meters.

Types of boards

There are so many types of boards that differ in purpose and technical characteristics. Depending on the degree of humidity there are:

• Raw - boards natural humidity. Can be used in the construction of low-critical structures.
• Dry - industrially dried. Drying is carried out to avoid deformation of the board and prevent rotting.

Depending on the quality of the boards, the material is distinguished:

• Selected grade - used in the automotive industry and shipbuilding;
• First grade - in addition to shipbuilding and the automotive industry, it is used in construction and furniture production;
• Second grade - used in the same areas as first grade material;
• Third grade - production of furniture and packaging products;
• Fourth grade - used for the production of containers and packaging.

  Calculation of floor boards: calculator, how to calculate

According to the type of cut, the boards are divided into:

• Radial - the cut passes in the middle of the trunk, at an angle of 90⁰, due to which the material has high strength and moisture resistance;
• Semi-radial - the cut is cut at an angle of 45⁰, the material is of an average price category;
• Tangential is the most economical type of cut; boards of this type are more susceptible to moisture. Possible deformation when drying.

Calculation of boards for the floor is important point at the stage of renovation or construction of a house.

Scheme for calculating boards on the floor.

The board is optimal material for subfloor.

But before you buy it, it is important to make a careful calculation, otherwise it may happen that you purchase too much big number units and spent large sum money. Those who think that if there is a shortage of coating there is always the opportunity to purchase the missing part of the material, you need to know that for a successful installation process they must be from the same batch. The most popular options for laying floors are the following types wood: wooden beams, unedged, edged and planed board. In each individual case, the required amount of lumber is calculated differently. This is due to the fact that each material has individual characteristics that must be taken into account during the calculation.

So, how can you make the correct calculation of the amount of lumber?

Find out the size of square meters

Scheme for calculating the required amount of boards for the floor.

1. To do this, the room is conventionally divided into a rectangle, if it does not have a strict rectangular shape, then it is divided into several rectangular parts, which are then measured. The measurements are designed to find out the area of ​​the room. The following formula will help you find it out: S = a×b, where S is the area, a is the width of the room, b is its length. The result will show you the required amount square meters covering that needs to be laid on the floor.
2. If the room does not have a rectangular shape, the area is calculated for each rectangle separately, after which the resulting figures must be added.

   Calculator for joists and floorboards

   For example: S = (a1×b1) + (a2×b2) + (a3×b3), where S is the final area, a1, a2, a3 is the width of 1, 2, 3 rectangles, b1, b2, b3 is the length of 1 , 2, 3 rectangles. You can use these calculations not only when the room is not rectangular, but also if you need to calculate the total amount of material in several rooms at once.

We calculate linear meters

In order to find out how many boards are enough to cover the floor, a ready-made rule will help you:

S = a×b = width wooden beam× linear meters.

Finding out the number of boards it will take to cover the floor is quite easy. To do this, you will need to use the following calculation: S = a×b×number of lumber.

Or with ready-made calculations:

Quantity=Sum of linear meters/b

So, to successfully calculate how much lumber it will take to cover, you will need the following:

• availability of ready-made formulas;
• calculator;
• information about segments a and b in the room;
• information about the thickness of the timber, its length and width;
• roulette;
• pencil and notepad.

Thus, anyone can carry out the calculations. Having the necessary formulas at hand and having minimal knowledge of mathematics, you can easily find out the square footage of the required lumber for lining the floor.

How to calculate the quantity and volume of lumber for the construction of your house, bathhouse, veranda

The first step is to decide on the scope of work and the materials from which you will build a house, a bathhouse or add a veranda. Coniferous lumber is best suited for any construction. Coniferous wood is light in weight, has natural antiseptic properties, and is most resistant to our climate.

If you have capital construction, then you will definitely need timber. But what size depends on your plans. For one-story light buildings, you can buy timber with a thickness of 100-150 mm. For taller and more permanent buildings, a thickness of 200 and above is required. It is also worth deciding on the construction budget. The most popular timber is planed. Its advantage is the lowest cost. It has a clear geometry and is easy to work with. Houses made of planed timber have good thermal insulation and accumulate less moisture. However, buildings made from such timber shrink slightly when dried. Therefore, do not rush to make a decision, think carefully about what you want to get as a result.

If you need wall cladding, flooring or an extension summer veranda, then you will need a board, edged or unedged

How to calculate the cubic capacity of lumber

Before starting any construction, it is important to correctly calculate the lumber. How much timber do you need to buy to build walls or make support structures, how many boards do you need to cover required quantity square meters, it is easy to calculate.

Calculation of floors, joists and floorboards

We multiply the length and width of the board and get the area of ​​one board. It is more difficult to calculate how many cubes of lumber need to be purchased at production. This information will be useful both for beginners in construction and for customers who want to control construction crews and be aware of the costs of building materials. After all, builders often cheat and include in the estimate much more lumber than is needed for the construction of one project. It’s not hard to guess where the surplus goes. Knowledge of basic calculations will allow you to avoid fraud and achieve high-quality work.

Lumber for construction load-bearing structures– timber, boards large section– are calculated and sold not by piece, but in cubic meters. The price in the price lists is indicated specifically per cubic meter of lumber. Correct calculation will help avoid extra expenses for construction and will not allow a shortage of material when you need to pay for another delivery and interrupt the work. Experienced craftsmen Usually they take lumber with a small reserve.

The calculation of cubic capacity depends on the type of lumber.

timber and edged board have clear geometric contours and constant values ​​of length, thickness and width. Calculating the cubic capacity here is simple: you need to multiply three known dimensions of the board, you get the cubic capacity of one board. To find out the number of pieces in a cube, you need 1 cubic meter divide by the cubic capacity of the board.

It is important to know that cubic capacity is determined by GOSTs; you can use lumber tables with ready-made calculations.

Table of cubic capacity of planed timber GOST

Enterprises that have been operating in the market for a long time and value their reputation strictly comply with all GOST requirements, and when purchasing lumber, the quantity will be clear and predictable.

An unedged board is not processed on the sides; different parts of logs are used on it, so its width is not constant. Therefore, it is only possible to calculate the volume of lumber needed by calculating the cubic capacity of one board only approximately.

For covering surfaces, piece lumber is used - small-section edged boards, planed boards, lining, imitation timber.

Experienced craftsmen quickly produce everything necessary calculations. For those who do not have much experience, it is better to contact specialists to avoid mistakes and correctly determine the type of lumber and its required volume. The greatest and most reliable information about lumber is possessed by manufacturers, and not by employees of resale companies. Therefore, for advice, consultation and purchase, it is better to contact the manufacturers.

The employees of our company “Industrial Integrated Technologies” will help you produce everything necessary calculations and decide on the amount of lumber. We are not trying to sell you as much timber or board as possible. Our task is to make your construction or renovation the least expensive and to provide you with high-quality softwood lumber in the quantity you need. We will deliver the goods to any point in the Vladimir, Moscow, Ryazan, Nizhny Novgorod, Ivanovo, and Yaroslavl regions.

As a rule, this work is carried out after completion heating season. Since at this time, the boards will not absorb excess moisture. The weather should be dry and sunny. It is best to use unplaned boards for rough flooring. While for the final finishing layer, milled and dried boards with longitudinal grooves for ventilation are used. Boards with a curved edge for a groove connection. As a rule, each such board is pre-treated with a decorative and protective composition.

During the installation process, you must follow the requirements:

• All logs must have good stability;
• The logs are laid strictly horizontally (exception when the slope is provided for by the project);
• Ensure ventilation of the space under the floor;
• Wood moisture content should not be more than 12%.

Mark and prepare the floor surface

First of all, we mark out the room and designate the places that need to be planned in order to achieve a uniform level (taking into account the thickness of the seams and the height of the brick). To add incompressible soil, use fine crushed stone or sand with a layer thickness of up to 5 centimeters.

After this, compact the entire surface. In those places where the logs will be located, we fill in crushed stone and also compact it into the ground.

Installation of logs

As a log, you can use a wooden beam measuring 50x100 mm. According to your program results, we install the timber on an already compacted surface.

If you plan to increase this distance between the lags, then in this case you should use a larger section of the beam.

If the subfloor base has concrete floor or slabs, then we install the logs directly on the concrete. In this case, you can use a smaller cross-section of the beam, since the bending load is almost completely eliminated. The rough flooring will act as a retainer for the second tier, and therefore a section of 50x50 is sufficient.

The distance between the logs will depend on the thickness of the material being coated. For example, 60 centimeters for a milling board, 40 centimeters for covering OSB or plywood.

When the logs are installed, we move on to waterproofing the space underneath them using roofing felt or other modern material.

Rough layer

When the logs are laid, we begin to install the second level, namely “rough boards”. To do this, all end joints should be made directly in the middle of the joists. To fix the boards, we use wood screws of the required size. You can either press the rough boards against each other or nail them at short intervals. In our case, this interval is determined by the value R.

Nails should be driven towards each other at a slight angle for strong fixation.

If you are laying with milling boards, then it is not enough to press them together by hand. For this purpose, special stops and wedges or tightening devices are used.

To fix the finishing board we use nails or wood screws.

The caps of fasteners should not be higher than the surface of the board. To do this you need to go deeper by 2 millimeters. The recesses can be treated with a special putty before painting the floor.

If you use screws instead of nails, you will need to drill holes and subsequently countersink each recess.

During the installation process, a gap of 10-15 millimeters must be left between the wall and the end of the joist or the outer boards, which will subsequently be covered with a plinth. This gap will serve as a compensator during the process of thermal expansion or moisture swelling.

The flooring is ready, now it can be covered with stain or protective varnish.

Before purchasing floorboards, you need to calculate how many cubes of lumber are needed to construct a certain structure. Wherein exact calculation can be done using a regular calculator, knowing the area of ​​the room and the thickness of the board. Such skills will be useful to you not only in order to calculate the volume of lumber for flooring, but also if you decide to build a house, because wood products are used to construct various structures.

Since the price of all lumber when sold is charged per cubic meter, it is important to be able to calculate the need for this particular unit of measurement. This way, not only the number of boards is calculated, but also other lumber, for example, timber, slats, etc. The thing is that products with the same cross-section may differ in length. Therefore, after determining the volume, you can understand how many floorboards there will be in one cube.

Important to know: when buying a board from valuable breed Wood products are sold individually. The thing is that the price of such coatings is too high, and when calculating in cubes there is a small error.

When calculating, it is better to use a regular calculator. This way you can get a more accurate result and take into account all the nuances of the future design of the house. Although, if you need to find out how many cubes of boards, for example, 50 mm thick, will be needed to construct a floor, you can also use an online calculator. He can perform such a simple calculation correctly. However, it is always a good idea to be able to count the amount of lumber by hand.

When building a house or laying a floor, the calculations are carried out in the same order:

1. First you need to calculate overall volume lumber in cubes. Knowing the moisture content of the wood, you can determine the weight of the entire material. This will help you decide which product delivery method to choose.

Advice: when ordering a carrier, it is better to indicate an inflated weight (10-15% more). This way you won’t have problems with the load, because the wood moisture content stated by the manufacturer may be a little more or less.

1. Next, knowing the dimensions of the boards, you need to calculate the volume of one element. Then you can find out how many products will be in the cube. Multiplying this number by the number of cubes, you get total number floorboards for your floor design.

However, such a simple calculation is applicable for edged elements, because they are processed on all sides and when they are stacked, there are practically no gaps left. To calculate how many cubes of unedged boards are needed for a floor, you will have to use a correction factor, because due to the untreated sides of the product, too many gaps will remain when stacked.

Calculation example

Let’s assume that in your house you want to cover a room with dimensions of 5x6 m with a 50 mm thick floorboard. We calculate the volume of lumber and the number of products in the following sequence:

• Find the area of ​​the room: 6x5=30 m².
• Since we decided to use a board with a thickness of 50 mm or 0.05 m, the lag step can be 1 meter.
• Knowing the thickness of the element and the area of ​​the room, we obtain the volume of lumber: 30 m² x 0.05 m = 1.5 m³.
• Now using a calculator, you can calculate how many floorboards you will need. To do this, knowing the dimensions of the floorboard, we calculate its volume: 2m x 0.05 m x 0.13 m = 0.013 m³. Now we divide the total volume of lumber by the resulting number for an element with a thickness of 50 mm: 1.5: 0.013 = 115 boards.

Thus, using a regular calculator, you can calculate the need for other lumber for building a house: paneling, timber, slats.

Calculating the boards for the floor is an important point at the stage of renovation or construction of a house.

The board is the optimal material for a subfloor.

But before you buy it, it is important to make a careful calculation, otherwise it may happen that too many units will be purchased and a large amount of money will be spent. Those who think that if there is a shortage of coating there is always the opportunity to purchase the missing part of the material, you need to know that for a successful installation process they must be from the same batch. The most popular options for laying floors are the following types of wood: wooden beams, unedged, edged and planed boards. In each individual case, the required amount of lumber is calculated differently. This is due to the fact that each material has individual characteristics that must be taken into account during the calculation.

So, how can you make the correct calculation of the amount of lumber?

Find out the size of square meters

1. To do this, the room is conventionally divided into a rectangle; if it does not have a strict rectangular shape, then it is divided into several rectangular parts, which are then measured. The measurements are designed to find out the area of ​​the room. The following formula will help you find it out: S = a×b, where S is the area, a is the width of the room, b is its length. The result will show you the required amount of square meters of coverage that needs to be laid on the floor.
2. If the room does not have a rectangular shape, the area is calculated for each rectangle separately, after which the resulting figures must be added. For example: S = (a1×b1) + (a2×b2) + (a3×b3), where S – final area, a1, a2, a3 – width of 1, 2, 3 rectangles, b1, b2, b3 – length of 1 , 2, 3 rectangles. You can use these calculations not only when the room is not rectangular, but also if you need to calculate the total amount of material in several rooms at once.

We calculate linear meters

In order to find out how many boards are enough to cover the floor, a ready-made rule will help you:

S = a×b = width of the wooden beam × linear meters.

Finding out the number of boards it will take to cover the floor is quite easy. To do this, you will need to use the following calculation: S = a×b×number of lumber.

Or with ready-made calculations:

Quantity=Sum of linear meters/b
