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



Veils in the corners of the cut. Comparison of Canadian and traditional Russian cutting

The specialists of the company “Log House Rus” have experience of construction of wooden houses of manual cutting using almost all existing technologies of cutting. You can order from us a house of traditional Russian cutting, a cut of cutting in a Canadian cup (with a veil), an improved Canadian cup (with a veil and a thorn), a cut of a house or bath of Norwegian cutting (Norwegian cup for a loaf ).

But, as welcoming hosts, we must tell you about the advantages and disadvantages of a particular method so that you can choose the way to build your house or bath with all the necessary information.

In this section we will compare the construction of a cut into a Russian and Canadian cup for a round log, more traditional for Russia. The main difference of the Canadian cup is the presence of a veil. Houses built according to these two technologies are easy to distinguish even visually by veils in the area of cross-cuts. More difficult is the case with an improved Canadian cup, which additionally includes a chip. It plays a crucial role in insulating the corners of the house and ensuring the lack of accessibility of the walls, but we will talk about the spikes separately in the . relevant section.


So let 's analyze the processes of cutting Russian and Canadian cups. For your convenience below are diagrams reflecting 3 stages of life of the soob for Canadian and Russian bowls. Let's consider on - to an order.

Stage 1. (Figures 1 and 2). The loom has just been manufactured and stands on the site of a construction company. The appearance of both options is beautiful: the gaps are minimal, the appearance is pleasant.

Stage 2. (Figures 3 and 4). There passed 2-3 years. During this time in the cut, or rather already in the wooden house on your site, there were serious changes related to the shrinkage of wooden structures. For information: depending on the initial moisture content of logs, the diameter of logs decreases by 5-10% during drying. Accordingly, the shapes of the bowls, the gaps in the cups and the slots change. Of course, cups of both types are subjected to shrinkage (Figures 3 and 4), and additional gaps appear in the Russian cup and in the Canadian cup, the sinks settle, filling the formed spaces.

Stage 3. (Figures 5 and 6). Of course, logs cannot hang in the air, as shown in Figures 3 and 4 (Stage 2 was introduced artificially for ease of understanding of the shrinkage process) and they will settle, occupying the space released. But this is where Russian and Canadian cups behave differently. If in the Russian bowl after shrinkage of the upper log there are sufficiently large gaps (Fig. 6), which will have to be closed with linnojut or packets, then in the Canadian cup, due to the presence of veils and triangular shape of the bowl there will be jamming of formed gaps, warm and, importantly, beautiful cut will remain.

Figure 5 shows the pin to be described in the next section.

To understand what the idea really looks like, we cited a few photos.

Figure 7 shows a log with characteristic veils on both sides (the second veil from this angle is not visible). Pay attention to the slot in the upper part of the log - it is intended for the previously mentioned stud. In addition, mark two props in the upper parts of the lower log - this is also an important element of the technologies we apply, they will be discussed in the section Unloading propil.

Figure 8 shows a view of the resulting wall with characteristic curtains at the corners.

Probably, you have a question - why did our ancestors not use these technologies, did not apply the idea and the chip? The answer can be a photo in Figure 9, where the master of the company "Log House Rus" virtuosically cutting a chip in a Canadian cup. Pay attention to his tool.

With good skills and using modern technique along with the classical trait and axe, it became possible to do very difficult operations to fit veils and spikes for Canadian and Norwegian cups quickly enough. Making it one axe is really difficult.

It should be noted that not all companies engaged in the construction of wooden log houses have perfectly mastered these techniques. Therefore, you always have the opportunity to choose the best option in terms of quality/price ratio.
