Wooden house made of round timber. Original projects of wooden houses made of rounded logs

A high-quality cottage is not necessarily a stone building of two or three floors. No less reliable and at the same time beautiful and environmentally friendly is a house made of round timber. Such a cottage will become family pride.

A round log is a log prepared in production, rounded, sanded or calibrated, which has a single round cross-section along its entire length with a permissible deviation of 0.8% from its total length. The surface of round timber, as a rule, is ideally cleaned and treated with antiseptics and fire retardants at the production stage.

Important: a log can also be called a round timber manual cutting, which is processed exclusively with an ax, as is done in Belarus (in Kobrin) and in Russia. But here the diameter of the wood may diverge somewhat at the two ends of the log. And therefore, the masonry of the house is carried out in this case with a constant change in the diameters of the wood in each crown, in order to compensate in this way for differences in sections and not to disturb the horizontal masonry of the crowns.

Choosing wood for round timber

All houses from round log, as a rule, mounted from coniferous species tree. However, the properties of each type of wood are slightly different:

  • Thus, pine logs are the most popular for the construction of a wooden house. The cost of such wood is much lower than other types of wood. However, pine copes well with temperature changes and retains heat well. The only disadvantage of pine is the formation of cracks when the logs dry out.
  • Larch. More expensive type of wood for installation one-story house or two-story cottage. With increased humidity levels, larch becomes even stronger. That is why it is used for laying the lower crowns of the house.
  • Spruce. Most often used for installation of all interior walls Houses. The spruce log has a smooth light shade over the entire surface. In addition, spruce enriches the air in the house with valuable aromas. pine resins. Spruce is used less frequently for laying the external walls of a house, since the tree has fibrous structure, which opens when moisture hits the log.
  • Fir. It has the highest cost among other types of wood, so it is used quite rarely. Cedar wood can also be compared to fir. A house made of these types of wood will be beautiful and durable, but very expensive. There is no need to talk about how much this type of wood costs.

Advantages of a log house made of round timber

The features of a wooden house made of round timber create an increased demand for the construction of cottages from this material. The main advantages of log cottages include:

  • Absolutely environmentally friendly material;
  • The high breathability of wood, which forms optimal microclimate in the house;
  • The low thermal conductivity of round logs allows you to economically spend resources on heating the cottage in the cold season and provides warmth in the house;
  • The evaporation of valuable coniferous resins into the atmosphere during the construction of a house and its operation has a beneficial effect on respiratory system household members;
  • In addition, log houses are distinguished by their durability (they can last about 80 years or more) and the ability to build cottages in seismically dangerous regions.

Types of round timber for home installation

To build a round timber house, you can use one of the types of logs that the construction market offers. The quality of each of the presented types of wood is the same, the only difference is in the type of wood processing. So, you can buy this round timber:

  • Rounded log. This type of log is simply processed by removing upper layer(bark) and the next one (bast) using a scraper, removing branches and resin pockets. As a result, round timber has the densest base on the surface. This wood processing technology is successfully used in Kobrin (Belarus).
  • Sanded log. It is this type of round timber that has discrepancies in thickness at its different ends, since during its processing only thin layer bark and branches. At the same time, the goal in production is not to give the log a single cross-section throughout its entire thickness.
  • Calibrated log. Construction material, perfectly adjusted in diameter. All elements have the same cross-section, which simplifies the installation of crowns at home.

Important: when performing work using any type of log, voids and gaps between the crowns are inevitable. Therefore, professionals recommend filling the free space well with insulation. Dry moss has proven itself very well in this case, which is also an antiseptic for wood.

Calculation of the amount of logs

Before you start building a cottage from round logs, you need to calculate how many cubes are needed per house finished material. Accurate calculations will allow you not to overpay for an extra tree. The calculations are not difficult to perform, the main thing is to know the design length of the walls of the house. Let's take a house as an example, the perimeter of which will be 6x6 m.

Important: when designing a log house made of round timber, it is important to consider that standard length logs 6 meters. And therefore the length of the wall should be equal to this indicator. If you want to make the house larger, then a competent architect places the joints of the logs along the length in the cuts (in those places where perpendicular walls meet). A different design method is considered a gross mistake. Similar projects houses made of round timber cannot be used.

So, we perform the calculation as follows:

  • We will use round timber with a cross-section of 28 cm as a building material. It is worth remembering that a larger cross-section of the log will ultimately lead to savings in material, and therefore in the construction budget.
  • In addition to the cross-section of the log, it is worth knowing the height of the log house. As a rule, the height of the walls of one floor is 2.4 m. In our calculations, we will take 3 m as an indicator in order to have some supply of material.
  • So, now we divide the height of the wall by the cross-section of one log, that is, 300:28 = 10.71. We get 11 logs for one wall and add to this value the log for the lower crown of the house. In total we have 12 round timbers on the wall of the house.
  • The resulting number must be multiplied by the number of walls of the cottage, that is, by 4. As a result, we get 12x4 = 48 logs needed for the construction of the outer walls of the cottage. But round timber is not sold individually. It is sold in cubic meters. Therefore, you will have to calculate the required volume of wood in cubic meters.

It is worth knowing that for each log diameter there is a different amount of round timber per cubic meter of material. The table looks like this:

  • Log diameter 180 mm - 6.5 logs per m3;
  • Log 220 mm - 5.3 pcs./m3;
  • Round timber 220 mm - 4.38 pcs/m3;
  • Log 240 mm - 3.69 pcs./m3;
  • Log with a cross section of 260 mm - 3.14 pcs./m3;
  • Log 280 mm - 2.7 pcs./m3.

That is, in our case, for one cubic meter of log with a diameter of 28 cm there are only 2.7 pieces of wood. Now we simply divide the number of logs needed by the number of pieces per m3 - 48:2.7 = 17.77 m3. We round it up to 18 m3 and go shopping for building materials.

We assemble the log house

You can make a cottage out of round timber with your own hands, if you have at least some carpentry skills. But first you will have to mount (make) the foundation for the cottage. As a rule, a shallow shallow base is installed under the log house. It must be waterproofed at the stage of pouring the solution, and also reinforced with steel rods. The foundation is waterproofed from above with roofing felt and bitumen mastic, but only after the concrete has completely dried.

Important: do not forget to make vents in the foundation so that the wooden structure can breathe from the floor. Otherwise, the tree will rot faster.

Wall installation

The walls of a round timber house should begin to be laid on a backing board. It will protect the lower crowns of the frame from rotting. It is better to use moisture-resistant larch as a material for the backing board. The board is laid strictly horizontally on a waterproofed foundation. In this case, the lining should be anchored to the base and additionally treated with bitumen mastic.

The first crown of logs is already mounted on top of the backing board. Round timber is joined at the corners in several ways:

  • "Into the bowl". This method requires additional processing of the wood to form bowls to join the wood at the corners. This method is considered the most aesthetic and at the same time warm. That is, cold bridges are practically excluded, provided high-quality styling insulation between round timbers. With this method of laying, the log should have a Finnish groove (small notch round section along the entire length). Thus, the upper round timber fits more tightly onto the lower one, which makes the cottage warmer. This type of joining of logs is also called “in the oblo”.
  • Connection "in the paw". This installation method wooden houses made from round timber is also called a “cold corner”. Here the ends of the logs are trimmed in such a way that they take on a trapezoidal cross-section and join each other at an angle of 90 degrees. This method of joining the corners of a log house is more labor-intensive, and its result is not always pleasing with high-quality heat in the house.

Key points when working with logs during installation

Building a house from a log must comply with certain standards and rules. It is thanks to a competent approach that the log house will be strong and reliable. long years. Even if you decide not to build cottage, and a log house with an attic and a balcony, as shown in the photographs below. So, the basic principles of installing a log house:

  • Before laying, it is advisable to dry all round timber and treat it with antiseptics and fire retardants.
  • When installing logs, they must be fixed with wooden dowels (pins prepared in advance from hard wood). The dowels are driven into grooves drilled in the logs, driving them to their full depth.
  • The dowels should be located in every 3-4 crowns with a step of 1.5-2 meters and with an offset of the dowels hammered below (in a checkerboard pattern).
  • In the proposed window and doorways you need to drive the dowels to the entire height of the opening.
  • After the house is ready, it needs to be given time to shrink (1-2 years). And only after that the openings for windows and doors are cut out.
  • It is also necessary to caulk the log house only after it has settled.
  • As finishing houses from round tree The log is sanded and varnished.

Roof of the house

The roof of the log house will be installed after the house is completely settled. And this is neither more nor less – 1.5-2 years. Otherwise, the roof may suffer greatly and the work will have to be redone.

The installation of the rafters is carried out on the mauerlat, which is the upper crown of the log house. In it, appropriate cuts are made for the rafters. The first truss is then assembled on the ground and lifted up. Attached to the Mauerlat using metal corners. Next, all other trusses (rafters) are installed according to the scheme in 60 cm increments. The roof is sheathed with lathing, hydro- and vapor barrier, and then covered roofing material. At this point, the construction of the house can be considered completed. A fully constructed wooden log house requires only final interior design in country, chalet, Mediterranean or classic style.

Rounded logs are a popular construction material used to build wooden cottages, country houses, bathhouses, log houses and other structures. His distinctive feature- maximum proximity to natural form tree trunk, which makes it possible to erect buildings that have an attractive and authentic appearance. The rounded log has a rounded shape and is manufactured industrially. Each element undergoes mechanical processing - rounding, during which the top layer is removed and the material is given a strict rounded shape. Then the drying process occurs and only after this the workpieces are treated with special compounds and impregnations that improve aesthetic and performance characteristics. On some workpieces, special bowls are additionally prepared for grooves, tenons, and ridges, so that construction site ready-to-use items arrive.

Advantages of houses made of rounded logs

Log houses made of rounded logs are one of the most popular types of buildings due to a number of advantages:

  • high environmental friendliness. When producing rounded logs, glue and other chemicals that negatively affect health are not used;
  • neat and attractive appearance. The construction of houses from rounded logs is carried out from blanks of the same diameter, having an even, smooth surface, which ensures high aesthetics and originality of the design;
  • no need for external finishing. The undulating relief is their peculiar business card, which allows you to significantly save your budget when building a house;
  • durability. Wood is a durable and wear-resistant material, therefore, subject to the right technology When built, a house made of rounded logs can last for decades;
  • good thermal protection. Wood has excellent thermal insulation characteristics.

In addition, the construction of houses from rounded logs does not take much time. The blanks do not require editing, fit perfectly together and fold into the frame. Therefore, if you have decided to order a house made of logs, you can be prepared for the fact that in just a few weeks a finished structure will grow on your site.

The main mistakes in the construction of log wooden houses.

Log houses have faithfully served people for thousands of years. Solid wood houses give their owners the incomparable pleasure of living in a comfortable microenvironment. Solid wood has high heat capacity(2.4 times higher than that of ceramic bricks), which allows you to smooth out daily temperature fluctuations. Also, the porous structure of wood allows you to naturally regulate the humidity in the room through cycles of absorption and evaporation of moisture. The log house is relatively resistant to movements of the soil and foundation. The wooden surface often does not require any additional treatment other than sanding and coating with antiseptics to create beautiful interiors.

However, only properly built wooden houses will provide comfort to their owners. The construction of a log house requires high carpentry qualifications at the 6th category level. Without experience and qualifications, it is almost impossible to cut down a wooden house without mistakes. And mistakes during construction can negate all the advantages log house. Houses built with errors are easy to recognize: builders or owners have to additionally insulate them and sheathe them outside and inside in order to hide defects and eliminate through-blowing of locks in the corners and crown joints. One of modern options houses made of solid wood, practically devoid of the disadvantages of log houses, are houses made of laminated veneer lumber. Thanks to the features of this technology, blowing through seams and cracking of wood in such houses is practically impossible.

In this article we will briefly touch on the most common mistakes in the construction of log houses.

  1. Errors in preparing a log house.

Mistakes when choosing materials for construction.

According to GOST 9463-88 “Round coniferous timber”, round timber from pine, spruce, fir and larch is suitable for building houses. Larch is the most expensive material, the hardest and most resistant to rotting. Spruce has a lower density, excessive knots and is prone to more cracking. The optimal tree for building a house is pine aged from 80 to 120 (140) years, grown in the northern regions (Arkhangelsk, Angarsk, Karelia) on dry sandy soil, at least 24 meters high. The best pine logs have a dark red or yellow-red core color, indicating a high density of wood. More loose varieties have a pale yellow core. The forest of winter felling, contrary to folk legends, actually has more high humidity sapwood (25-50% higher than in summer), a larger amount of starch and, therefore, is more easily affected by fungi. You can identify round timber from winter felling using a qualitative starch test: a stroke is applied to the debarked wood with an iodine pencil. If the stroke turns blue, this means a tree cut down in winter.
For construction, timber with such defects as mushroom blue and colored sapwood stains (with a depth of no more than 1/20 - 1/10 of the end diameter), wormholes (no more than 5-10 pieces for 1 linear meter), side cracks from shrinkage no more than 1/20 -1/5 of the end diameter, trunk curvature no more than 1-2% (1-2 cm per 1 linear meter). Logs used for construction must have a slope (thinning of the log towards the top) of no more than 0.8 cm per 1 m of length.

Rot (sapwood, rotten, heartwood) and tobacco knots (decomposed brown or white knots that crumble under load) are not allowed in round timber.

The minimum diameter of round timber for a residential building is 22-24 cm. The width of the grooves should be at least half the diameter of the log, and in the northern regions it can be increased even more. With a smaller groove size, the consumption of timber is reduced, but the thickness of the inter-crown seams becomes smaller, and the house becomes colder.
Cutting corners can be done without a residue “into the paw” or with a residue - “into the corner”. Cutting into a corner makes the connections more reliable and the frame more stable. In addition, the allowance of wood better protects the lock from the effects of atmospheric factors. Cutting “in the paw” is usually used for subsequent cladding of corners or the entire log house. For residential buildings, the device for connecting logs in the corners must have internal locking elements that prevent through blowing of the corner (connecting logs “into a bowl” with a pre-stop or “into a block” with a pre-stop). Due to its geometry (an inverted bowl), cutting “in the middle” allows for better moisture removal and faster drying of the joint. Cutting internal locking elements requires a highly qualified carpenter; such work takes more time and is more expensive. Otherwise, the corners of a residential building will be protected from blowing only by tow ( thermal insulation material). This is one of the main disadvantages of houses made of rounded logs, where log connections are made industrially without additional internal locking elements.

Moisture content of timber for construction. SP 64.13330.2011 " Wooden structures» allows the use of raw solid wood for the construction of houses with humidity up to 40% at following conditions: the predicted shrinkage of wood should not interfere with the structure and pliability of the joints, and the timber itself must be subjected to antiseptic treatment and conditions must be provided for it to dry out and be protected from moisture. It is optimal if the log house dries out, installed in place on the foundation and under the roof. Drying period from 6 months to 1 year. If the log house stood with the seller in piles (individual parts of the log house with 5 crowns each, convenient in height for processing) without a roof for 6-12 months, then with a high probability this means that the tree will be affected by rot. It is permissible to purchase log houses that have stood under the roof.

It is important to understand that the higher the humidity of the timber, the greater the shrinkage of the tree, and the wider the inter-crown cracks and cracks in corner joints will open (especially with cutting defects), the more the tree will crack.

Why don't they cut down houses from dry wood? Dry wood has greater density and hardness, and is much more difficult to process. The rounded log is subjected to chamber drying after processing upon request. However, the tree chamber drying may bend during the process of gaining equilibrium humidity at the construction site. They use Finnish and Karelian dead pine of equal moisture content in construction, but this is already an exclusive product. In addition, a correctly assembled frame made of raw wood, when dried in the assembled state, “sits” in place, reducing the size of the through cracks and, accordingly, the coefficient of blowing through the walls. It is important to know that wood can be painted (not treated with antiseptics) only if its moisture content does not exceed 15%. Otherwise, the wood will crack severely when drying. Therefore, treatment of log houses is only permissible with vapor-permeable antiseptics. Treating a damp (damp) log house with a vapor-proof antiseptic will also lead to cracking of the wood as it dries.

For dowels (dowels), only dry (no more than 12%) straight-grained wood without knots should be used. Birch dowels must be antiseptic.

Bonding logs to metal element s (cuts of reinforcement, long nails) are not recommended, since moisture accumulates at the media interface, and the metal elements become centers of biological destruction of wood. Typically, unscrupulous builders use reinforcement to fasten and “tension” crooked logs, which then leads to disruption of the normal shrinkage of the log house, the formation of cracks and bulging of individual logs. It is strictly forbidden to pierce with nails corner connections logs, as this will interfere with the movement of the tree during shrinkage, and will contribute to the formation of cracks (nails after the wood shrinks will rise above the surfaces).

Types of timber processing for construction.
The most traditional for Russia is round timber. In Scandinavia they use a carriage (from the Norwegian “lafteverk” - log house) - logs hewn on two opposite sides onto two edges, or a semi-carriage - hewn onto one edge with inside logs The cost of a hewn log house can be 35-50% higher than a log house made of round timber. When processing round timber, builders sometimes leave sections of the bast (underbark) unremoved. According to the standards, no more than 20% bast can remain on the round timber. However, it is better to remove the bast completely by sharpening (planing), since the bast contains many polysaccharides, which are an excellent feeding ground for microorganisms and insects that can damage the wood. Also, when trimming, young layers of sapwood, less resistant to damage by fungi and insects, are removed.

2. Errors in the assembly of the log house.

Waterproofing must be laid between the first casing and the foundation. Until now, for some reason, builders use for waterproofing a short-lived material based on cardboard - roofing felt, in which through holes and cracks in 7-10 years. For waterproofing it is necessary to use modern bitumen-polymer materials with a service life of 25-50 years. Of course, a complete lack of waterproofing is unacceptable. The use of a backing board under the casing reduces heat loss through heat transfer from the log house to the foundation, and reduces the risk of biological destruction of the casing. According to the requirements of SP 64.13330.2011 “Wooden structures”, such wooden linings (pillows) should be made from antiseptic wood, mainly hardwood (oak, aspen). If necessary, backing boards can be replaced with new ones. Replacing the frame crown is a much more labor-intensive procedure. Lower crowns houses must be protected from moisture. The greatest damage is caused by splashes of precipitation reflected from the ground and snow piled against the wall. To protect the logs from splashes and snow, it is recommended to raise the foundation above the planning mark by at least 40-50 cm.

TO additional factors The protection of the log house includes splash-proof canopies protruding above the base, long roof overhangs (75-120 cm) and equipping the roofs with gutters and pipes.

Orientation of logs when laying. Every tree has a natural curvature due to wind loads as the tree grows. When laying logs, they must be laid with the curvature upward so that the loads from the overlying structures compensate for the bending of the wood. If this principle is not followed, the logs will stick out to the sides. Normally, the deviation of the crowns of chopped walls from the horizontal per 1 m of length should not exceed 3 mm.

The size of the inter-crown gaps should not exceed 1 mm. With the Russian felling system it is quite difficult to carry out this condition, since as the wood dries, the cracks open up. The Norwegian cutting system with a wedging longitudinal groove and a sliding self-jamming lock has an advantage, in which, as the wood dries, the logs shrink relative to each other, reducing the size of the inter-crown cracks.

In Russia, they traditionally continue to insulate the roof gaps of log houses with natural materials such as flax, jute, felt, moss, etc., which are not elastic, are susceptible to biological destruction, and are a breeding ground for microorganisms and insects. All of these materials require repeated caulking. Meanwhile, in Scandinavia they use it as interventional seal elastic self-expanding polyethylene foam tape, the use of which eliminates the need for repeated caulking.

If possible, you should avoid joining logs in crowns along the length. Such connections weaken the structure of the log house, and the walls of the log house may become deformed. The logs used in the structure should be as solid as possible. And you definitely shouldn’t make connections at the intersections of walls, where load concentrations occur.

Shrinkage and swelling of wood along the grain is more pronounced than across the grain. Therefore, all vertical posts and columns must be equipped with jacking platforms and shrinkage compensators, which are tightened to the required amount of shrinkage, which can last up to 6-8 years or more. Perhaps a more aesthetically pleasing option is to install shrinkage expansion joints at the bottom of columns, where they are less noticeable.

It is not recommended to cut openings for windows and doors in the log house until the end of the first active drying period of the wood (6-12 months). During this same period, you should not hem the floor, ceiling or sheathe the walls, as this will interfere with normal ventilation and drying of the wood.

Special attention It is worth paying attention to the ventilation of the underground space when installing wooden floors. The minimum cross-sectional area of ​​one vent must be at least 0.05 m2, and total area there should be at least 1/400 of the underground area. It should be noted that this ceiling design is already archaic. In the world, they mainly use floors on the ground, which make it possible to use geoheat and avoid problems with humidity in underground space and the entry of radioactive soil gases into the house.

3. Errors in finishing a log house.

When installing window and door openings, we should remember that minimum distance between the openings is 90 cm. The walls must be reinforced with dowels. For installation in log houses it is better to use windows and doors with frames at least 10 cm wide, which does not allow window and door block deform during secondary caulking of the house.

The fastening of frame bars for door and window frames should be sliding - without the use of nails, since the shrinkage of a wooden house can take quite a long time. Above the windows and doors, compensation gaps are left under the heaving of the top log for shrinkage of 5-8% of the opening height.

It is better to use self-expanding elastic for sealing window and door frames. sealing tapes. Conventional polyurethane foam can deform when expanding window frames, and when the wood shrinks, cracks form. If it is used, then after hardening it should be covered outside from exposure to the sun and moisture with waterproofing, vapor-permeable, self-adhesive butyl rubber tape. The inside of the foam should be covered with vapor barrier tape. Unprotected foam deteriorates quickly, as in the house in the photo below.

Finishing the inter-crown seams of the assembled log house after the end of the first stage of intensive drying (12-24 months) with glazing beads or rope is only decorative, contributing to the waste of money and time, but not protecting the walls from blowing. Modern elastic and vapor-permeable inter-crown sealants (for example, from the domestic manufacturer SAZI) make it possible to protect inter-crown cracks from through blowing and create an aesthetically pleasing appearance of the walls.

Application of inter-crown sealant.

External insulation of a wooden house. Most often, external insulation has to be resorted to when construction defects are discovered, such as through blowing through the walls. The main and most critical mistake is the external insulation of a wooden house with vapor-tight insulation (expanded polystyrene, polyethylene foam). In this case, the tree is deprived of the opportunity to dry out and is moistened, which increases its thermal conductivity and accelerates biological destruction. Clause 8.8 of SP 23-101-2004 “Design of thermal protection of buildings” requires the placement of layers multilayer walls in such a way that the vapor permeability of materials from the inside to the outside of a heated house increases rather than decreases.

Aesthetics of a wooden house. Often lovers of wooden houses, where all interior elements, such as walls, floors, ceilings, beams, railings, furniture are made of wood, find that, perhaps, they have gone a little overboard with the quantity wooden surfaces, which create a feeling of life in " wooden box" Changing furniture and painting walls comes to the rescue. However, it is wiser to plan contrasting surfaces in the house at the design stage. These can be floors, ceilings, kitchen countertops, steel elements of stairs and fences, decorative walls from natural or artificial stone.

Since ancient times, a wooden house has been a source of comfort, well-being and harmony. Today there are no original, fashionable solutions and innovative technologies do not reduce interest in wooden houses. Any project of a house made of round timber resembles a fairy-tale house. To make the fairy tale come true, we will help you find out the secrets and features of round wood buildings.

Features of round timber

At all times, forests are considered the wealth of any country. Especially if it is graded round timber, which is widely used in construction. The main use of round timber is its processing into lumber: edged and unedged boards, logs, beams and whetstones.

Trees with a trunk diameter of more than 18 cm are classified as round timber.

Round timber is distinguished by trunk diameter and size. Sawlogs are logs suitable for subsequent sawing into boards. Depending on the diameter of the log, the forest is divided into assortment. The diameter of the logs is measured at the top of the cut.

The diameter of a large group of logs can reach 26 cm, middle group- from 14 to 24 cm, and small ones from 6 to 13 cm. The length of the saw log can reach 4 m. Round pine forest is considered the most popular in suburban construction. Log houses made of pine round timber are distinguished by their excellent appearance, resistance to rotting and cracking, and minimal drying out.

The goodness and quality of round timber can be determined by the following signs: the tree’s bark should not fall off or traces of soot should be visible. Otherwise, the tree turned out to be dry before cutting down or there are traces of a fire.

To build a log house from round timber, logs with a diameter of 26-28 cm of the same thickness are used.

To build a house from round timber with your own hands means to erect a high-quality and environmentally friendly structure.

Projects of houses made of round timber

Any project of one- and two-story houses made of round timber begins with the selection of logs. In addition, when designing houses from round timber the main design parameters are: log diameter (cm) and volume of rounded logs (cubic meters).

To calculate parameters, it is recommended to use the On line calculation program. As a result of the calculation, the amount of material required to build a house from round timber will be obtained: logs (volume per 1 square meter of wall), dowels, boards, beams and bars, jute.

How should you choose logs for construction, and how should you secure the frame?

choose logs

Distinguish following types round logs:

Rounded

Calibrated

Sanded.

Rounded round logs have the simplest type of processing at woodworking plants, which involves removing the top layer. During the processing process, a dense base of wood remains, having an even cylindrical shape. Wood at this type processing completely retains its quality natural material and is ready for use.

A calibrated log is wood that has already been selected for certain qualities and sorted by diameter. Construction of a log house from calibrated logs is the most preferable option. The walls of houses and baths during construction have a smooth surface, thanks to the proportionality of selection.

A sanded log is lightly processed wood with a layer of bark removed and irregularities in the form of knots. Protective layer under the bark remains in its original state, preserving high strength structure and natural form.

The difference in the diameter of the top and base of the trunk is clearly pronounced. However, this type processing most fully preserves the advantages of wood. It was this type of wood that made the huts and towers last for 200 years.

Methods of fastening round timber logs

There are three ways to fasten and join logs and beams:

Horizontal

Vertical

Tortsevoy.

With the horizontal fastening method, parts of timber or logs are placed on a “cold” joint. As a result of the connection, a small gap is obtained, which is sealed.

Considered more technologically advanced vertical method, in which, when beams or logs are placed on top of each other, a “warm” joint is obtained.

Finally, the butt method allows the logs to be joined into a flat tenon located on the inside of the logs.

The corners obtained by joining the logs are additionally reinforced with grooves and tenons.

How to design and build a house made of round timber with your own hands

The design and construction of a round timber house is based on calculations required material and taking into account the soil characteristics on the site. It is important to remember that when building a house, you need to choose a foundation or foundation. Let us remind you that for light construction with low weight and number of storeys, it is possible to choose a columnar base.

To build a house made of round timber on swampy or water-saturated soil, you will need to build pile foundation. For the construction of one- or two-story capital log house on ordinary soils it is possible to install a strip foundation that is not buried.

Technology for building a house from round timber

When building a house from round timber with your own hands, it is preferable to purchase a complete house kit, ready for assembly. In the kit, all logs intended for construction are adjusted in size to each other and numbered. All that remains is to assemble it carefully. The weight of the logs is impressive, so it is better to work with 2-3 people.

Initially, holes are drilled between the logs for dowels, with the help of which the logs are, as it were, strung together and form a wall. The first to be attached are the dowels located in the corners, window and door openings. The fastening interval should be 1.5 - 2 m with the side length of the logs, and at the interval window openings 10 cm. To lay the first crown, use the largest and most even logs.

The lower base is trimmed to create a stable installation, and a “bowl” is formed in the log house. “Bowls” are semicircular recesses for attaching corners. Having formed a row of the crown, the insulation is laid. The construction of subsequent crowns is carried out with the laying roll insulation.
