Deformation of door or window openings is possible. This happens for several reasons:

• High moisture content of the wood used for the construction of the structure.
• Extreme shrinkage of the building.
• A serious departure from construction technology.
• The wrong type of wood.

It is quite possible to completely level the curvature of the openings or to reduce them to a minimum. It is necessary to use wood that has undergone special processing, including drying, for construction work, and to mount swarms.

Purpose of swarms

A swarm is a simple wooden block, usually with a square cross section. It is mounted at the end of the opening just before installing doors or windows. If this procedure is neglected, then the openings can be significantly deformed or skewed.

In inclement and rainy weather, wood is able to actively absorb moisture and increase in size, and on sunny days, decrease. Over time, the opening becomes weaker, so if you do not use swings, then the window structure or door frame will hang exclusively on the fasteners.

Manufacturing and preparation: tricks and subtleties

For the manufacture of rocky, it is necessary to choose exclusively high-quality, well-dried wood. The width and length of this element should correspond as much as possible to the size of the cut into which it will be mounted. The ideal length is usually 5-7 cm less than the height of the opening itself. Thanks to this difference, a strong stop is provided, designed to protect the opening from deformation.

Mounting

1. Use a chainsaw to cut a hole in the wall for the door frame or window construction... It must be treated with special compounds.
2. It is necessary to make a longitudinal cut in the inner part of the opening. Make sure that its depth matches exactly the thickness of the swarm. And the length of the cut is usually 5-12 cm longer than it.
3. Now you can start installing the rooks, and then start installing doors and windows.

A gap of 5-7 cm wide is formed between the swarm and the upper part of the opening, into which insulation is placed (for example, tow or flax fiber). They not only retain elasticity over a long period of time, but also help prevent the building from sinking. It is strictly forbidden to fill the gaps with construction foam. It is able to glue the logs together and disrupt the natural shrinkage process of the structure.

Conclusion

If you are planning to build a reliable and comfortable home, then do not neglect the swivel installation procedure. It seems that this is a primitive piece of a bar, but its functionality is difficult to overestimate. Only in this case you can not worry that the door or window openings in the house are deformed. Moreover, the whole procedure does not take any other time.

Royki

Construction wooden houses is gaining in popularity. More and more people are choosing ecological housing and moving to the countryside. All the benefits wooden house many articles have been written, and they are all valid. The disadvantages are not so numerous and, rather, not even disadvantages, but the peculiarities of operation and construction.

It's no secret that wood, a natural building material, tends to dry out. House made of wood or laminated veneer lumber should be stable. These processes take from several months to several years. As a result of drying and shrinkage, the geometry of the building changes. Of course, the most sensitive elements to changes in size and shape are the structures of doors and windows. Only precise setting of levels and gaps ensures normal opening / closing, absence of cracks and drafts.

For modern technologies shrinkage and shrinkage of a wooden house does not cause problems associated with windows and doors. With the correct construction of the building made of wood, namely in the process of preparing window and doorways, use "swarms" - a technological element that prevents a change in the size of the opening.

After the opening has been cut through, the beams at the end form an unsecured edge, which in the process of shrinkage can deviate from the vertical axis, deform the opening, and even lead to the loss of windows or doors. In order to avoid such complications, sawing is done at the ends of the beams forming the opening ( vertical slot). It is in it that they are inserted swarmand. They are made from wooden a bar of square section or from a metal corner.

Features of mounting the swarm

The installation of rooks requires compliance with some rules:

• Royka must match the prepared groove exactly.
• Installation is tight, but without rigid fixation.
• Box ka doors or window frame attached only to the swarm.
• The upper edge of the swarm should be 10-20 cm shorter than the opening.

For installation swarms it is very important to observe the last rule. Lowerthe th edge should firmly abut against the floor, if these are doors, or against the lower horizontal beam of the window opening. At the same time, the top edgeswarms must be shorter than the vertical cut into which it is inserted. Compliance with this condition ensures the possibility of normal shrinkage without deformation of the opening.

To the person who decided on construction of a wooden house, you need to be extremely careful when choosing a contractor ( construction company). Some of them forget to even just mention that there is a technology for studding door and window openings with swarms. Others, suggest the banal quality wooden houseas an additional option. "We will build a great wooden house for you, but if you want it to be of high quality, pay us more."

In a reliable construction company such as ours, pinning of windows and doors is not an option, but a technological standard of construction that ensures the quality and durability of doors and windows in your home.

It's no secret that profiled timber is a natural, living material. This is the main reason for the special love of private developers for him. Lumber houses have a lot of advantages and few disadvantages. The main ones are susceptibility to shrinkage, drying out and the appearance of cracks. This is because a solid timber loses its natural moisture over time and dries out. The process is invisible to the naked eye, but building structures react to shrinkage processes. The openings for windows, doors and gates were especially sensitive to the draft of the building.

Finished projects of houses from a bar, or made on an individual basis, must provide for protective measures in order to avoid distortion of openings during operation. As an option, the use of a thoroughly dried timber in the construction of a house. It gives less shrinkage. More effective method - to install swings for window and door openings. It's great when the developer has the opportunity to use both methods in combination.

What are swarms?

Swarms are called beams, usually square in section. It is installed in specially cut, vertically located, slots of the end parts of a window or door opening. Installation of a swarm in a log house, which gives:

• strength and stability of the configuration of the opening for a window or door block;
• exclusion of the possibility of "sagging" of the box after the likely shrinkage of the building;
• hassle-free installation of a wooden, metal or plastic block.

Any building product must be manufactured in compliance with certain rules, including swarms. So, what are swarms in a log house, and how to make them right?

1. For the manufacture of this, in fact, a thorn is used only completely dry wood.
2. The cross-section of the swarm must completely coincide with the geometric dimensions of the cut into which it will be inserted.
3. The length of the spike is made less than the height of the opening by 60-120 mm.
4. The difference in height of the opening should only be visible at the top.

It would seem that we are talking about a primitive piece of timber, but its functionality is significant. It reliably protects a window or doorway from bending. If you ignore the installation of the swarm, the sagging of the blocks will be inevitable and irreversible.

Opening device

To the question: what are swarms, the answer is received. Now you need to figure out how to install them correctly. The sequence of actions must be followed precisely to obtain the expected result. You cannot rush to fill the openings with blocks without properly preparing them. Installation of rooks in window and door openings is carried out as follows:

• On the sides of the hole for a window or door, a vertical cut is made exactly in the middle. Its section should be even, smooth. The resulting groove should be thoroughly cleaned.
• The cutting depth should be equal to the thickness of the swarm, and the length should be 60-120 mm more than the size of the prepared bar.
• All openings are processed in the same way.
• The swarms are placed in the nests prepared for them. They should fit very tightly. From below, the bar enters the groove without a gap. And the difference in height between the swivel and the opening remains free from above. The resulting space is called shrinkage. It is filled with a special insulation to avoid the formation of a "cold bridge".

Now you can safely install windows and doors in complete confidence that no shrinkage will affect their normal operation. Royki under metal doors or the gate is usually also made of a metal profile.

• too wet wood
• the type of wood is not suitable for building standards
• seasonality of construction and climatic conditions;
• violation of technological and construction processes
• acceleration

In order to avoid negative moments during the process of shrinking at home, you must adhere to the following rules

• First, apply exclusively quality material (the timber must be processed and subjected to special additional drying)
• Secondly, in construction works use swarms (these are wooden stumps in the form of a square section, which are used at the end of the window opening and doors, as an installation element).

What does the installation of swarms give

Installation of swarms, provides protection from deflection of openings. If they are not used, under the influence of shrinkage, the opening will become inappropriate.

Window swings

After the wall is made, at the timber, an edge that is not supported by any part of the building will be formed. After installing the window frame, the process of shrinkage of the structure will begin, while the timber weakens and the frame sags on the fasteners. By applying swarms on window openings, it is possible to minimize this negative process as much as possible

Door swings

When installing doors, in, the importance of swarms is no less great. After all, the doors are exposed even more high pressure due to their size and can be deformed. The use of a swath can minimize the effect of shrinkage. When installing rooks in doors, it is necessary to take special account of the gap between the wall space and the frame in order to avoid curvature. We must fix the lower part of the door end-to-end, and at the top we set a gap for the shrinkage process.

Constructive nuances;

When making swarms, it is necessary to consider the following nuances

• Natural shrinkage is usually 1/20 of the original space; dimensional quantity
• The width of the swarms should correspond to the space left for shrinkage, and the length should be slightly less than the opening itself

Installation of swarms

• At the ends of the opening cut for windows and doors, a longitudinal sawing is done
• In the prepared cuts, the swarms are installed, provided that they allow the house to sit down naturally
• Remaining gaps are filled

That houses made of profiled timber - this is a modern, reliable and profitable way of housing construction, no one doubts today. It is not surprising that houses, baths and outbuildings made of this material in last years can be found everywhere. List the benefits log houses can be infinitely long. However, in this article, we set ourselves the task of telling you about one drawback of wooden (including squared) buildings and ways to neutralize this drawback. It will focus on the natural moisture content of wood, and the problems associated with it.

Houses from a bar: the essence of the problem

As you know, wood is a natural material that was once a living organism. Like all living things, wood contains moisture. Over time, some of this moisture from the wood evaporates, and the wood begins to dry out and crack.

This may not be visible to the naked eye, but nevertheless affects the overall design. log housecausing deformation of window and door openings.

Shrinkage houses made of profiled timbermay depend on many factors.

First of all, it is the level of humidity and the variety wood material for construction, type of wood, season and construction technology.

Usually, shrinkage is most intense in the first three to four months after construction is completed.

Rojki: protection of timber houses from deformation and shrinkage

In order to neutralize negative influence to your log housethe problem described above, two complementary methods are used:

• Profiled timber is used for building a house, which has undergone additional industrial drying. The percentage of moisture in such a bar is not more than 20. As a result, less shrinkage and shrinkage of the finished house.
• Used when installing doors and windows swarms.

If everything is clear with a decrease in the moisture content of the material, then what is swarms for wooden houses, we suggest talking in more detail.

Royka for a wooden house is a special block made of wood with square section... This bar (swarm) is inserted into the prepared groove at the end of the window or door opening.

Roykihelp to effectively solve the problem of deformation of window and door openings. If we just cut an opening in the wall from a bar, and then install a window or a door in it, then, after a while, the drying out wood will make your opening too large, and the door frame or window frame will simply fall out of it. To avoid this development of events, between the frame or door frame establish swarms, reducing the negative consequences of drying and subsidence of wood to a minimum.

How swarms are installed

When installing swarms for log houses, as a rule, the following actions are performed:

• A hole in the wall of the house is cut out for a door or window, and its finishing is carried out.
• A longitudinal cut is made in the end part of the resulting opening. The cutting depth should correspond to the height of the swivel, and the length should be 6-12 cm longer than the length used swarms for a log house... This will give space for the shrinkage gap.
• After that swarms for wooden housesare installed in prepared cuts, and door or window frames are already attached to them. A gap (about 5 cm wide) is also left between the ends of the log house and the frames of windows or doors. This gap is then filled with a special insulation, which is also necessary for safe shrinkage at home.

Thus, applying in practice all of the above technologies, we achieve the absence in our log houses defects associated with shrinkage and drying of such a valuable natural building materiallike wood!
