Let's not hide that one of the most popular construction technologies wooden houses is a Canadian felling.

This technique is unique and is distinguished by the positive specifics of Norwegian and Russian technology collected in it.
Let us consider in more detail the most important nuances and features of this method.
The Canadian log house is distinguished by its features and specific specifics, which are important to study more carefully.

1 The cost is quite high due to the fact that the process is very labor intensive. However, the expense is compensated by the positive differences compared to manual cutting methods.

2 In Canadian cutting technology, several types of grooves are used: traditional semicircular and M-shaped. Main distinguishing feature Canadian cup - the presence of side tassels. To accurately cut through all the shapes, specialized equipment is required. During the marking process, a compass of a unique design is used. Carpenters use axes to finish cutting grooves and bowls. Due to the high complexity of the Canadian bowl, the most important equipment and tools are the high professionalism of the employees and their experience. Without this, Canadian logging is impossible. Without false modesty, we note that we are proud of our craftsmen - they have no equal in this labor-intensive task!

3 The finished Canadian log can be quickly distinguished from the rest; externally, it is created like this: a groove with edges is cut on top of the wood, and a “tail tail” is made at the bottom - a tenon. Because of this complex design the finished log house is not completely ventilated. After the shrinkage process, it jams itself.

Alternate stages of Canadian logging

If we do not take into account the nuances of wood harvesting and drying, then it is quite possible to divide all the fundamental actions into stages of construction of structures.

1 Having its own base, which is equipped modern equipment, we select all the necessary design parts. We divide them into suitable and not. When dividing, we take into account important factors: the size of the logs, technical condition after drying. If defects are detected, the wood is recycled. From wood that has obvious flaws, auxiliary lumber is made.
For Canadian log houses, we choose exclusively smooth wood, which is of impeccable quality and has the following dimensions: length from 6 to 12 meters, and diameter from 280 to 500 mm or more.
After this stage, our specialists perform primary processing - remove the bark. A special tool used to remove the bark (scrape) allows you to clean the surface as efficiently as possible and not damage the protective layer: “sapwood”.
Another effective method processing that our specialists use is “hydrobarking”. In this case, the bark is removed under the influence high pressure water.

2 The Canadian log house is delivered to the customer’s territory in the form of a carefully packaged structure. Delivery is carried out using special transport.

4 According to the markings created on the logs, the process of assembling the log house begins. Canadian bowls are compacted during assembly, which is guaranteed to eliminate blowing and also protect the frame from moisture and rotting. An accurate calculation of the percentage of shrinkage of the structure is made.

5 During the installation of the log house, it is antiseptic. In this case, professional products are used that are guaranteed to help eliminate any appearance of various fungi and insects.

The cost of this work varies in Moscow, but our company offers affordable prices for such High Quality housing.

Advantages of Canadian logging

Accordingly, the construction process is quite labor-intensive and complex, but thanks to the many advantages it is worth it.

Excellent thermal insulation, thanks to the extraordinary shape of the groove, a perfect connection of logs is achieved.
During processing, the entire upper layer is preserved, which has a beneficial effect on the main factors: freezing, cracking, twisting - all parameters increase. The room has its own microclimate.
High quality and natural beauty of textures make the house truly unique. Such a house does not require finishing, which significantly reduces overall costs.
It is worth considering the fact that the quality of a constructed house depends 90% on the experience of specialists.

Taking this into account, we propose professional services our company "Vityaz-Stroy". Our employees are highly qualified craftsmen who are guaranteed to build the log house of your dreams!

At all times, the quality of log buildings has been measured by their durability. The technology has been honed over centuries, with masters passing on their art from generation to generation.

Canadian cabin invented by Russian settlers who set foot on American soil at the beginning of the 18th century. Solid and beautiful have gained wide popularity in Canada, hence the name of the method.

Canadian log cutting technology

Canadian logging is used in the construction of structures made of massive round profile logs. The diameter of the logs varies from 30 to 60 cm, the thicker the log, the better. The “Canadian cup” frame is easily recognizable – a trapezoid-shaped bowl with side edgings. This technology allows the grooves to be firmly jammed and ensure that there are no gaps between the logs. During the shrinkage process, the log frame forms almost monolithic wall. Best materials for the construction of a Canadian log house - pine, larch or cedar, harvested in winter.

Each log used is selected with the utmost care.
Processing is carried out exclusively by hand, this preserves the top protective layer of wood fibers - sapwood.
Precise fit ensures that there are no gaps between the logs.
The layers of insulation are not visible, creating the feeling of a solid solid wood.
Creating a comfortable microclimate indoors - the house is warm in winter and cool in summer.
Unpretentious in operation - no work on insulation or elimination of cracks and cracks is required.

Initially, the Canadian log differed from the Russian and Norwegian only in the shape of the bowl, which, thanks to its trapezoidal shape, tightly fit the adjacent log during the shrinkage process. However, over time, additional tenons and grooves began to be used inside the bowl; with their help, it was possible to achieve a tight connection of the logs and ideal mating of the crowns. The junction of the internal groove and the tenon is called the “fat tail”; during the shrinkage process, the logs are tightly connected to each other, while the entire mass of the insulation remains inside, which improves appearance the buildings. To minimize defects arising during the drying process, it is used special technology- humiliation. A cut is made along the axis of the log; its depth ranges from 5 to 15 mm. Thanks to this, the log does not crack when dried and retains its original shape.

Economics of construction: comparing Canadian and Russian logging

The construction of a Canadian log house is an expensive process, but quite justified from the point of view of durability. You can visually distinguish a Canadian felling from a Russian one, even in a photo, by the presence or absence of characteristic knots in the cutting areas.

And yet, the main difference is the tenon in the “Canadian cup” - it is this that guarantees the absence of gaps between the logs and the high heat-saving characteristics of the building.

The technology in this case is much more complicated, and the cost of the log house will be higher than when using Russian log house. The time required is also higher, this is due to the complexity of fitting the tenons and grooves inside the bowl and careful sanding of the wood.

When choosing a cutting option, the percentage of wood shrinkage is first taken into account, because over time the diameter of the log can become 10% smaller. This will lead to a violation of the proportions of the cup and the appearance of cracks. Natural shrinkage is an inevitable process, and even the highest quality logs sag, creating cracks that will have to be filled with tow or other specialized material. It is at this stage that it becomes obvious advantage Canadian cutting before Russian: the deformation of the cups will be almost zero, and cracks will form extremely rarely. In addition, the shape of the cup prevents the accumulation of moisture, reducing the likelihood of rotting and damage to the wood.

The disadvantage of Canadian cutting can be considered the complexity of execution. All work is done manually, due to which the top dense layer of wood remains on the logs, ensuring high resistance of the building to impact environment. Increase in monetary and time costs for building a house by Canadian technology fully justifies itself in 5 - 7 years, the costs of insulation and repair of a Russian log house will result in no less amount.

Maintenance and operation costs after construction

The main cost item when operating a log house is ensuring the tightness of the walls. The cracks that appear during drying must be caulked. Houses built using Russian logging technology require caulking 2-3 times a year for 10 years after completion of construction. Caulking is the process of filling the resulting cracks thermal insulation materials– tow or jute fiber. This is a very labor-intensive task that requires special skills. Accordingly, the cost of work will be very high. The use of putties and sealants when caulking is unacceptable, since the process of natural air exchange in the layers of wood is disrupted, this leads to increased humidity and the development of mold and mildew.

Canadian logging does not provide for additional caulking of walls during the shrinkage process. A layer of insulation is placed in the crowns during construction; if the construction technology is followed, the walls reliably retain heat even in the most harsh winter. Thanks to the special shape of the bowl, the dried upper log is tightly connected to the lower one, forming a monolithic joint that does not require additional insulation. This is why Canadian log houses are often not lined from the inside, while heat loss is kept to a minimum.

Log housescan be built according to different technologies. Which one to use depends on many factors:

functional purpose of the building;
its total area;
the presence of a certain type of building material;
terrain and climatic conditions;

Cutting methods “with residue” and “without residue”

When making a log house using the “residue” method, or cutting “into a bowl”, a recess is cut out in the logs, and the next log is placed in it. With this, the logs protrude beyond the walls by a certain distance (25 cm on average). Thus, the material consumption increases at the rate of 50 cm for each log in the log house. Such costs are offset by good protection of the corners of the log house from wind and rain. It is believed that such a log house is superior in stability to other construction technologies. If the logs are processed carefully and efficiently, the building looks attractive and even decorative, moreover, it does not require any external or interior decoration walls This cutting method has many varieties:

Russian cup,
canadian cup,
Norwegian cup
German cup and others.

Today, the most common and technologically advanced methods are: "Norwegian castle" and "Canadian cup".

From many known methods construction of classical log houses, there are two technologies for cutting log houses that allow you to avoid the appearance of cracks when the house shrinks and do without constant caulking.

Canadian cup

Canadian cabin house "Canadian cup" there are undeniable advantages over other methods of making log connections. When cutting using the Canadian method, the log in the bowl and in the horizontal groove is adjusted especially precisely; there are no gaps at all with this connection. But this is not the most important thing. Gaps do not form even after shrinkage of the log house, which is explained technological features connecting logs. The Russian “cup” requires periodic caulking after completion due to the formation of cracks during drying.

The Canadian cup has the shape of a trapezoid. Due to the trapezoidal shape, the bowl does not form cracks during drying, since the upper log is pressed against the lower one during drying, settles evenly and becomes wedged in the trapezoidal bowl. In this way, the geometry of the entire structure is preserved; the logs do not form cracks and do not twist.

Norwegian castle

Norwegian cabin "Norwegian castle" made from a gun carriage. Such a log is made with a special profile: protrusions are made along the entire length of the log on one or both sides. For the carriage, only thick logs with a diameter of at least 270 mm are used. The thickness of hewn logs according to Norwegian standards for external walls should not be less than 200 mm. In such a house, specific triangular-shaped fastenings are visible in the corner joints, and the inter-crown heat-insulating materials are not at all noticeable, since they are located in longitudinal recesses.

When shrinkage of the log house occurs, the corner joints of the carriage are connected “wedge to wedge”, forming a very strong connection due to its own weight. This connection prevents deformation of the carriage. The wood dries, but no cracks appear, so the walls may not need to be caulked.

The logs retain their height, so when drying, there is no need to increase the number of crowns. Since some of the wood from the log has been trimmed, the dimensions internal space houses are getting bigger.

The carriage can be used independently for the entire log house, or can be combined with an unhewn round log.

The external attractiveness of the material allows you to do without exterior and interior decoration.

For log houses arranged according to Norwegian technology, use pine wood, or less commonly, others conifers. This wood is the densest and most resinous, and therefore less susceptible to rotting.

Durability of a log house

Log houses are particularly durable.

The log huts, built in the 17th century with just one axe, still remain. They, of course, do not look very modern, but they are in good condition and suitable for living.

A wooden house in Sweden it has been standing for 776 years. In the Swedish town of Mura, an old farm has been preserved, consisting of sixty wooden ancient houses. They have been preserved almost perfectly, and it is quite possible to live in them.

Canadian Cutting

The main advantage of Canadian felling, undoubtedly, is the minimization of gaps - cracks on the sides of the bowls, after the logs shrink. This advantage still does not 100% exclude the appearance of cracks at the joints of logs, as well as cracks on the log itself.

And therefore, the use of sealant, subsequently, and often during the construction stage, is INEVITABLE. And it turns out that talking about the absence of cracks becomes inappropriate. It is logical to ask: “Why then is this argument (about the absence of gaps) presented as an advantage? If the sealant closes ANY gaps anyway.

The second advantage is visual effect, since the planes of the cuts, even if they are poorly (not Canadian) executed, add positive sensations from the log house. However, this is, as they say, a matter of taste, and there is no arguing about tastes.

For “hunting is worse than bondage”, if a person wants, let him do it - We are “For”, with both hands!

The disadvantages include a significant reduction in the thickness of the logs at the joining points, i.e. in the corners. Especially with double stitching (both above and below). This, as a consequence, reduces the thermal insulation of the corner.

And also, since the sapwood is completely removed from the corner, the working life of this connection is reduced. It's simply durability. Illiterate execution further aggravates this problem.

Want to know our opinion about Canadian logging?

The myth that CANADIAN CUTTING is Cool.

You can PR and Exploit any popular topic, but there is a Fact that you cannot avoid. You can only “close your eyes” to it. Or Don't see it because you haven't studied the topic.

Where is the ancestral home of the Canadian logging?

It's very simple if you ask yourself:

Where could the North American Indians have developed log houses? If they mainly led a nomadic lifestyle, then why did they need log houses? True story Russia has deep roots. Those who don't like it know this very well. And the great-grandchildren of those Russians who walked with their feet across the lands of once Russian Alaska are learning more and more.

If the well-forgotten old is passed off as “new” - this will be another brand and money out of thin air. Because there are many who like to repackage a well-known product into a “new” one. It sells better that way. Since “it differs in that...” And there is more freedom with arguments.

This connection method log structure justified only in certain cases. And not without its shortcomings.

To start...

Name: “Canadian cabin” comes from an artificial surge in the popularity of this sophisticated technology in Canada. Its roots are in Russia, for it was brought from there, as one of the many varieties of Russian cutting. This technology is found in different nooks and crannies of the world. And residential buildings made of logs using this technology acquire a certain special attractiveness due to the geometry of the connections. Especially if they are executed COMPETENTLY, because there are also “other” executions...

It’s called “As we could” and “as we could.” This is “refinement”. One can only laugh at this kind of “refinement”, because the log becomes so thin at the joints that the cups sometimes break off.

To prevent the groove from “climbing” onto the edge, you need to sacrifice the groove, making it Already. And such a narrowing of the groove width will naturally worsen the thermal insulation. You can simply compare: will the groove width be 15-18 cm (up to 25 cm), or 7-8 cm, and sometimes 6 cm? These are places in the wall 6 cm thick! Well, where is this good?

Disadvantage of Canadian Logging The problem is that too much thickness is cut off from the entire log mass. This is undesirable for a log house. Moreover, the undercuts in the bowls are hewn out. And it turns out a little deep.

If you make an upper notch, and then another lower one, then from the entire mass of the log there remains an “isthmus” with a cross-section of less than 30% of the log’s cross-section. A small triangle from the circle remains.

Usually they put a thick tangle of insulation in there and think that everything turned out great. But what can you do with the fact that the log is cut by 70-75%, 25-30% remains and the edges are very poorly protected? And you have to make special efforts to ensure that they can withstand loading. Especially transportation. Otherwise, it may simply not withstand the shock or pressure on the road or during loading.

There was a case in our practice: A team was cutting down a house using Canadian technology, with double slabs. This was a long time ago and was a big curiosity back then.

The foreman with sparkling eyes told everyone about the Canadian cabin. Even then, from his stories, we had questions about this technology.

When we looked WHAT they are cutting down, our fears were confirmed. And then they cut, one might say, “a C grade.”

The connections in the corners seemed so weak, since the logs in the corners were heavily sawed through, that they seemed to be very unreliable. And one element, it was a one and a half meter long extension under the balcony, was somehow restless to look at. Not only was the thickness of the bowl “nothing”, but it also had no lower stems. It felt like he was just hanging in the air and was about to fall.

I say to the foreman: “Well, it might fall off you.” And he answered me that he was not going to correct the mistakes of the designers, as it was drawn - that’s how we do it.

Well, as a result, it fell off when loading it into the car. And what the balcony is now supported on is unknown. How they solved this problem is not known.

And it turns out that you need a competent approach, taking into account these nuances, which allows you to avoid such troubles.

If Canadian logging is what you want, we can perform it this way,

What You will sleep peacefully.

To do this, you just need to deviate from some of the canons established for Canadian logging, and everything is guaranteed to fall into place.

Hybrid Post ® Beam technology, which appeared in Canada only about 20 years ago, combined traditional Canadian logging and the Post ® Beam method of constructing frame structures from logs, significantly expanding the possibilities of architectural design of facades.

In the simplest version of using hybrid technology, a log first floor is built using classic Canadian felling, and the attic and porch of the house are built using frame method Post ® Beam. However, in Lately Both construction methods are increasingly being combined within the same floor.

CANADIAN CUTTING

Wooden house construction in North America its origins owe to emigrants from the Old World, who used European traditions and construction methods.

IN new technology(the first standard regulating it was dated 1976, the latest - 2012) the marking system, joint design and principles of combating shrinkage from the Norwegian felling system were taken as a basis, but the log house was made not from a gun carriage, but from a round log.

Thus, Canadian logging is considered to be a kind of symbiosis of Norwegian and Russian methods making corner connections.

The Canadian cup has a trapezoidal saddle shape. On the upper part of the lower mating log, two cuts are made at an angle of D5-500 (the exact value depends on the diameter).

The minimum length of the cleats is two log diameters, the maximum width of the top of the seat saddle is 90 mm. A correspondingly shaped groove is cut out in the upper mating log, the depth of which must be at least 25 mm greater than the height of the saddle.

As a result, a so-called saddle gap is formed above the top of the connection of the lower log with the upper one, which will disappear when the mating crowns shrink as a result of wood shrinkage. For a long time, Canadians limited themselves to such a cup, which made it possible to obtain a fairly strong and dense self-jamming connection called “into the saddle.” But it had one drawback - it did not prevent the wood from twisting when drying.

That is why later a special tenon was introduced into the design of the castle, cut into the bowl of the upper mating log, and a corresponding groove was provided at the top of the lower saddle. (According to some experts, the tenon also helps reduce the ventilation of corner joints, but not everyone agrees with this thesis). Then another innovation appeared - they began to make a saddle-shaped lock not only at the top, but also at the bottom of the log, resulting in the so-called diamond bowl. As a result, today there are three options for connecting to a Canadian cup: with bars (“in the saddle”), with bars and a tenon, as well as with upper and lower bars and a tenon.

Another feature of the Canadian felling is the original shape of the longitudinal grooves in the mating logs. So, in the lower part of the upper log, a double groove (doublegroove) in the shape of the letter W is cut, and in the upper part of the lower log, a single groove (veegroove) in the shape of the letter V is cut.

True, domestic carpenters, gradually mastering a new technology for themselves, abandoned the use of both, replacing these grooves with a lunar semicircular groove, more familiar to Russian cutting, but with sharp lower edges (as in Finnish or Norwegian cutting), which allows you to reliably protect the groove from the weather inside intercrown insulation. The width of such a groove, as a rule, is at least 12 cm, but can reach up to % of the diameter of the log, making the connection much warmer than in the Canadian version.

Types of log corner cuts

1. Russian felling

The connecting bowl is located at the bottom of the top log, which makes gusset more resistant to precipitation
2. Russian fat tail cutting

It has an improved bowl with a special spike - fat tail. On the opposite side of the log, a groove is created for the tenon of the next log
3.Norwegian cabin from gun carriage

Reminiscent of fat-tail cutting, but the bowl is formed by inclined cuts, thanks to which, when the wood dries out, the joint self-seals under the weight of the crowns
4.Canadian log cabin

A symbiosis of Norwegian and Russian fat-tail cutting - inclined edges and a groove for a tenon are created on the top of the log, which is located in the lower bowl of the upper log

POST® BEAM TECHNOLOGY

The Canadian Post ® Beam logging is essentially a direct descendant of the now almost forgotten Russian logging (in a post, in a rack, in a lock), in which the frame of the building is assembled from vertical posts with grooves selected along them. Logs are inserted horizontally into the latter, at the ends of which spikes corresponding to the geometry are pre-cut.

Moreover, at the bottom of each horizontal log a longitudinal recess is made and filled with compaction (moss, tow, etc.), as in other types of Russian logging. But if in Rus' the space between the log posts was usually filled with so-called whips (thin tops of trunks), and similar technology used mainly for the construction of unheated outbuildings, then in Norway, and then in Canada, residential buildings were successfully built on it.

The difference was that in Norway a carriage was used to fill the spaces between the posts, and in Canada rather thick logs were used (their diameter was at least 300 mm).

And the posts themselves in the Canadian version of the felling have become more powerful - their diameter physically cannot be less than 400 mm, since in the area where the filling logs adjoin them, it is necessary to make cuts on the posts with a width of 200 mm. Application of logs large diameter- this is not only a tribute to fashion and beauty, but also an opportunity to reduce the number of crowns of a log structure, which, in turn, reduces heat loss through the walls.

It should be noted that in the Post ® Beam technology, the openings between the posts can be filled not only with logs, but also with insulated frame structures, blocks (including those made of foam materials), as well as glass. The wall frame is firmly connected with the equally powerful slab roof structure, forming almost a single whole with it.

Left: Canadian bowl - a traditional version. It involves making ridges (“cheeks”) only on the top part of the log. Suitable for joining logs of any diameter, and especially for combining small and large diameter logs
Right: Canadian Diamond Bowl
The notches are made on the upper and lower parts of the log; the result is a more labor-intensive, but unusually beautiful connection. Only suitable for joining large diameter logs

CANADIAN CUTTING - CONSTRUCTION PROCESS

Manufacturing of necessary elements and preliminary assembly of the house, the design of which combined both log and frame technology, were produced on a specially equipped construction site located near timber harvesting sites.

Thus, it was possible not only to select the most suitable blanks for each structural element, but also to control the work of carpenters at all stages, and in addition, to use lifting equipment without time restrictions. But the main advantage of such an organization of work is the following.

Structures of this type are built using not only Canadian cups, but also grooves and tenons of a wide variety of shapes and sizes, which must be carefully (and therefore long) carried out and scrupulously adjusted to each other, otherwise the house will be impossible to assemble.

That is why the production of log and frame elements and preliminary assembly take many months. However, the customer is not present at preparatory stage, but only watches how the skeleton of a future house is assembled on his site in just a few days from brought logs.

Upon completion of the work, the builders marked each structural element and drew up an assembly diagram (it is a necessary appendix to the construction contract). The frame was then dismantled, packaged and transported to the client’s site, where it was reassembled, but now on a foundation, which was a monolithic slab.

The frame was mounted on wooden dowels, which gave rigidity to the wall structure. When installing the roof we used technological methods and details that allow elements rafter system free to slide relatively log walls during shrinkage of the log house.

The progress of the construction of a house made of Siberian cedar logs with a diameter of 35 to 100 cm is presented in sufficient detail in the photographs, so we will comment only on the stage of constructing the roof, which remained “behind the scenes”. A continuous flooring of planks was built on top of the rafters, thus creating a ceiling.

Through the vapor barrier, in increments of 60 cm, boards with a cross section of 200 * 50 mm were nailed to it, installing them on a narrow edge. In the cavity between the boards, slabs of mineral wool insulation with a total thickness of 200 mm were laid in layers, covered with a vapor-permeable membrane, which was pressed to the boards with counter battens with a cross-section of 50 * 50 mm. Next, a pre-treated antiseptic compound was attached to the counter slats. wooden sheathing from a block with a cross-section of 100 x 25 mm, and to the last - a flooring made of metal tiles of the color chosen by the owners.

ADVANTAGES AND DISADVANTAGES OF CANDY CUTTING

As we have already noted, recently in our country there has been increased interest in Canadian logging and the associated Post ® Beam and Hybrid Post ® Beam technologies, about which many laudatory reviews are published. Of course, these methods have certain advantages, but not all of them are absolutely indisputable. Let's start with the advantages of the Canadian logging itself, first of all with its undoubted advantage.

In the Canadian bowl, double-sided cuts are performed only in the lower log. The result is a cone-shaped “saddle”-zamon, which self-seals as the wood dries out. This solution eliminates the appearance of cracks in the corners of the log house and eliminates the need for repeated caulking.

But it’s quite possible to argue with other theses.

The Canadian bowl is a stronger and warmer compound than the Russian bowl.

Compared to normal round bowl cutting into a flare or into a flap, then the Canadian one is really stronger. However, such cuts as in a fat tail or in a flange with a cut are in no way inferior to it in strength, and a cut in a hook is even superior.

If we talk about the “warmth” of the connection, then with a log diameter of 300 mm, the thickness of the wood at the junction of the logs in the Canadian cup in the narrowest part does not exceed 200-250 mm. The width of the insulation embedded in the saddle gap in this zone is a maximum of 70 mm. The thickness of the wood layer when joined into a Russian bowl is almost equal to the diameter of the log. At the same time, the latter is insulated over the entire area. So which of the two compounds is warmer?

The next statement: it is less labor-intensive to implement. Yes, making a trapezoid with almost flat edges by cutting with a chainsaw is really easier than, as in the Russian version, cutting out a bowl with an axe, adze, or even a chisel.

But let’s not forget that making a Canadian bowl also involves a rather complex double drawing of logs, as well as a large volume manual grinding. That is why the price of Canadian log houses is quite high. It is also necessary to take into account the influence of processing methods on the durability of wood. The saw loosens and “fringes” the surface of the wood, which even after sanding remains vulnerable to the penetration of dampness. The ax smoothes the outer layers, closing the pores, which prevents moisture from penetrating inside the product. So which option is better?

Now about Post ® Beam technology. Like all frame methods construction, it allows you to build houses on permanent place their location with greater speed (assembly lasts 1-2 weeks). And proceed to finishing walls can be installed immediately after the installation of the frame is completed (the structure is not subject to shrinkage).

But if we talk about the Hybrid Post ® Beam technology, in which a log structure is combined with a frame structure, then when they shrink, they will behave completely differently. Of course, the situation can be saved by screw shrinkage compensators installed under each pillar support, but only on the condition that the need for their regulation will be monitored experienced specialists. In general, the construction of such houses - structurally complex, with elements having a huge mass - should be trusted exclusively to professionals in this technology. Unfortunately, we still have few of those.

And yet the appearance on Russian market The new technology cannot but rejoice, because it opens up wide opportunities for architects to implement various ideas designed to make each house unusual and even unique, like a work of art. Besides. Hybrid Post ® Beam saves money cash thanks to the use of lighter foundation options ( frame construction lighter than logs) and reducing the start time for finishing work.

DIAGRAMS FOR THE SHRINKING PROCESS OF RUSSIAN AND CANADIAN BOWLS

1. The shape of the bowl partially follows the surface of the lower log. The insulation is laid over the entire area of the bowl

2. The logs are adjusted to each other more accurately. The insulation is placed in the so-called saddle gap

3-4. Both types of cups undergo changes during drying. Depending on the initial moisture content of the logs, their diameter decreases by 5-10 96. Accordingly, the shapes of the bowls and the size of the gaps in them change. The log house begins to settle

5. Large gaps remain at the bottom of the cup, which will have to be caulked with flax jute or tow.

6.Due to the triangular shape of the bowl, the connection self-seals. No need to caulk

Filling frame walls

The connection of the ends of the horizontal elements with the vertical logs-posts was made using the “tenon-groove” system: the groove was selected in the posts (a), and the tenons were cut at the ends of the filling logs (b). At the bottom of each log, a longitudinal groove was selected, into which final assembly an inter-crown seal was inserted. They also sealed the tongue-and-groove joints.

Additional Information

CLEANING THE BARK WITH A JET OF WATER

When processing wood, it is important to preserve it natural properties. That is why devices are increasingly being used to remove bark from a log using a pressurized water jet. With this debarking, the metal of the tool does not come into contact with the most important protective layer logs - sapwood and does not damage it. As a result, wood not only preserves natural beauty and surface texture, but also better withstands environmental influences.

CENTURY TRADITIONS

The main tool of a carpenter, as many centuries ago, is a “draw” - a tool similar to a compass: when marking, one leg slides along the surface of the lower log, the second draws a line on the upper one. Another ancient, but equally indispensable tool is an adze, with which a longitudinal groove is made. This ax smoothes the outer layers of wood, closing the pores and preventing moisture from penetrating inside the product.

LITTLE TRICKS

It is no secret that when cutting logs across the edge of the cut with a chainsaw, thin chips become overgrown. To prevent their appearance, a simple technique is used - a knife is first drawn along the cut line. In this case, chips may appear only on the cut part of the log
