Secrets of building of wooden houses:

German and Canadian technologies of "Curtaining of external corners"

Use of metal couplers for connection of logs in notches

Notches in the house corners (Canadian notch)

Use of a special dowel (thorn) in the Canadian notch

"Undercut": application of a special gap on an axis of logs

Drawing antiseptics on all latent surfaces of a log shell

Use of technological cuts for management of formation of cracks in a log

Making of apertures under joiner's products

Features of technology of building of houses from an oval-flatten (a semioval log)

Joint application of a round log and an oval-flatten

 


Application of German and Canadian technology for hanging the outside corners to reduce the gaps between logs after shrinkage of the cut at home or bath

Sometimes the appearance can be deceitful. This also applies to the technologies of making cuts of wooden houses and baths from round logs.

Look at the appearance of the cut immediately after the construction. Notice the size of the gaps between the logs on the interior of the walls (that is, between the corners) and on the corners themselves. The gaps are minimal - everything looks fine. But let 's not hurry, wait 3-4 years. During this period the cut will shrink due to drying of logs (5-10% of the diameter of logs).

What will be the result. If the cut shrank equally on the exterior corners of the house and on the interior walls, everything would be wonderful - the gaps everywhere would remain insignificant and your house would remain as warm and beautiful.

But here the peculiarities of wooden house construction, about which, unfortunately, many Russian companies do not know. Masters of “Log House Rus” have many years of experience in construction of wooden houses, not only for Russia and CIS countries, but also for Norway, Germany and other countries of Western Europe. And we always try to learn a new one, adopt useful experience, implement it, receiving gratitude of our Customers. This was also the case with this methodology passed to us by our German colleagues.

 
Curtaining of external corners

So what happens to our cut in a few years. The nuance is that logs in the outer corners always have greater humidity than the material of the main (central) part of the wall, as a result of which the shrinkage of the outer corners will be smaller. And if so, it will turn out to hang logs in the central part (they will rest on angles), which will inevitably lead to slits, especially on the internal surfaces of the walls.

For elimination of consequences of this problem the large quantity of hermetics and pastes is issued in the world. Pay attention to the following photos (it is a photo by Perma-Chink). Would you like to close up seams in your house for the rest of the life? If no, it is necessary to pay attention to an offered technique. Certainly, it will not solve all problems with shrinkage, but will essentially reduce them.

What the German (it is also an element of Canadian) technology of construction of cuts offers. Please note Figure 1. Additional clearance between logs approximately 5-8 mm is left at the outer corners. Note that for the interior parts of the walls this gap should not exceed 2 mm.

Due to the deformation of the logs caused by uneven drying and shrinkage of the crowns at the corners and in the central parts of the walls, the final clearance along the entire length of the log will be uniform and minimal (Figure 2).

What this looks like in practice is shown in Figures 3... 6. Notice the gaps between the logs at the corners of the pipe.

By the way, Figure 3 shows the hand of Master “Log House Rus”, applying the line of the future slot with the help of a special tool - features.

Let you not be embarrassed by the shade of logs in Figures 5 and 6, these photos are taken at the beginning of February this year in overcast weather.

We hope that the acquired knowledge will help you to order and build a House with a capital letter, which would not disappoint you not only now, but also in the future.

The material of this section is very close with sections of "undercut" and "features of shrinkage of walls made of an oval-flatten" and if you are not familiar with them yet, we advise You to read.
