Okosyachka do it yourself

When building a country house, special attention should be paid to such crucial elements of wooden structures as window and door covers. And this is due to the well-known seasonal phenomenon called “shrinkage”, which necessarily manifests itself during their operation. When preparing window and door openings, you should always bear this in mind and take care in advance that the possible shrinkage does not lead to unpleasant consequences, namely, to the deformation of these structures.

To exclude the possible deformation of the window and door openings, the latter are placed in a special salary, called an okosyachkoy (or obsadom). Thus, okosyachka in a wooden house will allow you to protect the structure of the bindings from its natural shrinkage.

Structurally, the casing in a wooden house consists of 3 parts:

• side racks (sidewalls);
• the so-called "master";
• window sill (for windows) and threshold - for doorways.

There are several ways to make an okosyachki, each of which will be discussed in more detail in the next section.

Casing production methods

Among the well-known techniques of manufacturing casing boxes, the methods described below are most often used.

"The mortgage bar"

Such an octopus is a structure consisting of a bar with a cross section of 50? 50 cm and an edged board of 50? 150 mm or more (depending on the size of the logs). Mortgage or guide bar is mounted on the sides of the structure in such a way that the crown crowns could freely move along it as along the guide (if they have corresponding slots).

The widespread prevalence of this method can be explained by its low cost and ease of execution.

In thorn monolith

This method involves the manufacture of the roundabout of window and door openings from a solid rectangular beam, having in the section "T" a shaped profile (with a spike in the middle).

When assembling the walls, logs stacked in the log house are “strung” with their grooves on this spike and during subsequent shrinkage the structures can move freely along it. In this case, a regular edged board with a thickness of about 50 mm can be used as the apernik (upper lintel).

In the deck

With this version of the design, even before mounting the box, vertical ridges are made at the ends of the wall logs, and a groove is made in the side racks-bars of the tusk. When assembling the box, first of all, the lower window-sill is mounted (it is also called the threshold), after which the side racks of the ossyachki, laid with a roll compactor of one type or another, are inserted into the spikes.

The upper part of the prefabricated box ("apex") plays the role of a strut of its side posts; at the same time, a small gap is left between it and the upper crown of the log house, which is used as a shrinkage gap. This gap must be filled with sealing material of the type you choose. At the final stage of the design of window openings on them are mounted slopes and trim, covering the areas adjacent to the ends of the log house.

The main stages of assembly

All operations for the manufacture of okosyachki are strictly regulated and are performed, as a rule, in the following order:

• preparation (marking and cutting) of the corresponding opening;
• its design under your chosen option of the round-up;
• assembly self siege;
• installation in it of the window or door block.

When preparing the seat, it is necessary to clarify its dimensions with regard to the distance to the floor level. For windows, in particular, it should be of the order of 80–90 cm. After this, the opening is marked with the obligatory use of the simplest tools for checking - the construction plummet and level.

The opening dimensions should be about 40–60 mm larger than the window construction, which is connected with the need to leave shrinkage (compensatory) gaps.

Depending on the technology of your choice, the work on the design of the opening for an octagus includes the preparation of a groove or a crest in it. The installation of the okosyachki is also taking into account the features of the selected type of casing technology, that is, in compliance with all the rules and procedures for assembling this structure. At the final stage of work, the direct installation of a window or door block is made into the prepared casing.

In the manufacture of okosyachki with your own hands, you should always remember that its use is justified only in the case when the age of the house does not exceed 10 years. For long periods, the use of these technologies is not necessary, since the structure has completely exhausted its shrinkage resource.
