in windows and doorways mount wooden bars (mortgage bars) with strict rectangular shape. They are installed at the end of the wall. Installation is carried out before the installation of frames and door frames. The purpose of the bar is to “support” the opening and the structures installed in it, which, after its installation, will not change their shape and deform.

Well-dried wood is used for the manufacture of swarms. The bar should not change its size and shape during the shrinkage of the house.

How to make the right rod?

• You need to choose the right wood for the manufacture of the bar. It must be well dried, free of defects (rot, cracks).
• The bar must have dimensions that are suitable for the cut created for it in the wall. Royka should not sit freely in it.
• The length of the bar supporting the opening should be 5–10 cm less than the height of the groove (a reserve for wall shrinkage, which will prevent the frame or door from warping when the wood shrinks).

Mounting

To install the bar, you must first make a cut at the end of the wall to its entire height. A bar will be installed in this hole. Important point- the swivel should completely fill the cut. All its parameters (width and depth) must fully comply with it. Only in this case will it be possible to prevent changes in the geometry of the opening in the wall. The bar is mounted in such a way that the shrinkage gap remains only from above.

The groove for the rod must be even. It must be cleaned to remove all the bumps that formed on the wood at the time of cutting. If this is not done, voids will remain between its walls and the bar.

The free space above the bar is not left empty. It is filled with flax jute fiber. It does not interfere with the subsidence of the structure, in addition, it is a good natural insulation. Its use will prevent the passage of cold and wind through the voids of the cuts for swarms.

After installing the supporting bars, you can proceed with the installation of frames and doors.

The main mistakes in the manufacture and installation of racks

• Making a bar from uncured wood. This causes the swarm to shrink along with the walls of the buildings. Hence, it does not prevent the deformation of the structure.
• No gap in shrinkage groove. Royka will interfere with deformation wooden walls, strong pressure will be exerted on the beam.
• You can not fill the space in the groove above the bar mounting foam. It penetrates even into small cracks, firmly gluing the wooden elements of the structure. This will help to disrupt the shrinkage process at home.

Despite the seeming simplicity, a royka is a serious structural element of a wooden house. It allows you to prevent mechanical impact on window and door structures. As a result, they remain intact, they do not need to be changed due to the fact that they are warped, prematurely failed. Therefore, do not refuse to install rods in openings for windows and doors. Moreover, their installation does not require significant financial and time costs.

Timber construction - a combination the latest technologies and ancient traditions. Often, not all terms are clear to the layman, because the proposals of the developer company are unclear, especially when they require a separate fee.

One of those odd moments is windows and doorways .

When ordering the construction of a wooden house, it is worth knowing in advance what a casing bar is, whether it is needed and, if necessary, whether it is worth paying extra for it.

What are roi and what do they look like?

Roiki(otherwise - casing bars) - vertical elements necessary to maintain the geometry of the walls in the area of ​​window and door openings.

At first glance, it is not clear how such a simple detail can be so important, because the opening beam looks like an ordinary rectangular bar, more often a square section. But the need to install a casing bar is high, especially in a house that is built from a bar of natural moisture.

They mount the rods of window openings, cutting a groove under them in the end part of the bars. It is worth knowing that the length of the casing bar should be 6-12 centimeters less than the height of the opening. During shrinkage, the upper beam and those under it will fall. The rod moves freely along the groove prepared for it, without changing its position relative to the vertical and reliably holding the position of the log beams in the opening.

In what cases are rods necessary?

Any home built for permanent residence, requires strict adherence to technology, and royki are provided for in it.

But their installation is especially important in the following cases:

• construction from a bar with a high degree of humidity;
• complex construction of walls with a large number of openings, their large-scale dimensions;
• if the plans include the installation of PVC window and door blocks (in this case, the casing has a special design).

The only case when you can do without a casing bar is the construction of a house or a bathhouse from glued beams of large sections. But this material is not cheap in itself and it makes no sense to save on the installation of swarms.

Royki - the key to straight walls in your home

To begin with, pay attention to the warranty obligations and clauses of the contract with the developer company. Usually there is a guarantee for the integrity of wall structures. If this is so, do not listen to the arrived workers who offer to improve the structure with the help of casing bars, otherwise, they say, "the walls will lead."

With such an attempt at extortion, call the head office of the company that ordered the construction of the house or bath. Inform that when changing the geometry of the walls, you will contact about warranty service, and the developer will be required to correct the shortcomings. This method is suitable only if the contract really spells out responsibility for the integrity of the structure.

Is it necessary to overpay for the installation of casing in the openings of the log house?

This is a moot point. A conscientious developer company lays the cost of swarms in the price of building a house in advance, because they are necessary. More "savvy" covens offer construction at a reduced price, putting forward their proposals for the installation of swarms and other supposedly additional services are already in place after the future owner of the house has concluded a contract with them. In this way, they easily find those who want to save money, later still receiving money for the installation of casing bars and other operations that are mandatory for high-quality construction.

Decide for yourself whether you want to order the construction of a house in a company where everything is transparent or trying to save money (in the end, often overpaying). What if you have already signed an agreement and only now realized that you are dealing with the above-described covenants?

To save the situation, do the following:

• carefully read the contract again, check the warranty period;
• make it clear to the builders that you are not one of those who will let things go “on the brakes” in case of shortcomings;
• if the contract contains a clause on responsibility for the integrity of the structure, discuss this with the foreman, foreman or other manager and explain that in case of deformation of the walls you will demand the correction of the defect under the guarantee.

These three simple steps will help you to show that you are not “barely born”, and will not allow violation of your rights.

In the absence of responsibility for maintaining the geometry of the log house during operation and the warranty period, you have no choice but to pay extra for the installation of slats. If construction has not yet begun, refuse the services of such performers.

Wooden houses are becoming increasingly popular with private developers. The leading position among them is occupied by houses made of timber.

Timber buildings. Shrinkage problems

This lumber is manufactured, and has all its inherent properties. For example, natural moisture. Over time, a house built of timber dries out and shrinks.

It may not be visible visually, but it has an effect on the structure of the log house. Negative influence necessarily. And if timely measures are not taken, it can cause distortions of openings intended for the installation of windows and door blocks.

The amount of shrinkage of a log house is variable and depends on a significant number of external factors. The biggest influence on this indicator is exerted by:

• The type of wood from which the beam is made, and the degree of its moisture content;
• Type of timber (planed, profiled);
• Season of construction work;
• Used technology for the construction of the log house.

Royka - a structural element that protects the house from deformation

The craftsmen of the Wood-Beam company are well aware of how wood behaves in construction. Therefore, we offer the customer two options for solving the problem:

• Use for construction a bar that has previously undergone chamber drying;
• Install doors and windows using a rail.

This is the name of a bar with a section of 50 * 50, made of dry wood. Its length is 50-120 mm less than the height of the opening into which the rod is mounted. Royka successfully and effectively solves the problem of possible deformation of openings. If this product is not installed, then the following picture occurs: after a certain time, the drying timber, due to a change in its own dimensions, can deform the door frame or window block. In order to prevent such a development of events, swarms are installed.

Therefore, not a single house made of profiled timber of natural moisture is built by us without the use of special technology installation of windows and door blocks, which allows minimizing the negative impact of shrinkage and maintaining the geometry of openings and the entire building as a whole.

Roika making

The "correct" swarm requires correct manufacture. For this, the following requirements must be taken into account:

• Its production requires high-quality source material, kiln-dried hardwood. It is not desirable to make it from lumber of natural moisture. An exception may be the option when the bar is made of a material corresponding to that from which the wall profiled beam is made (from scraps of this beam). In this case, their compatibility is guaranteed;
• The cross section of the product sets the width of the cut, which will need to be done to install it. The length of the cut is 50-120 mm less than the height of the cut (usually it is taken equal to the height of the block that will be installed in this opening). This difference, left at the top, provides free shrinkage of the structure. And the stop formed by the swarm eliminates the curvature of the free ends of the timber;
• The rod is placed strictly along the central axis of sawing, performed at the ends of the timber from which the walls are laid.

Mounting sequence

The algorithm for installing the swarm is as follows.

1. Holes are cut in the wall for the subsequent installation of window and / or door blocks. The walls of the opening are processed.

2. In the inner part of the opening, on its side walls, a longitudinal cut is performed strictly in the center, which is a smooth groove, machined from the inside (cleaning). Its depth is set by the section of the rod, and the length exceeds the same value of the installation product by 5 - 12 cm.

3. Royki are installed in the cuts prepared for them with some effort (tightly). At the same time, their lower part descends to the base of the prepared opening.

4. After that, windows and door blocks are installed.

Please note that after their installation between the upper edge of the opening and top block remains free space 40-60 mm, designed to compensate for the shrinkage of the log house. It is filled with insulation and sewn up with platbands.

The latter cover the space left for future shrinkage. Cashing, most likely, is partially deformed in the process of shrinkage. However, this disadvantage is easily eliminated. It is enough to remove it and file it a little. It is strictly forbidden to use mounting foam to process this space. Since this can become an obstacle to the normal subsidence of the timber.

Racks are not only reliable protection against deformation for door and window structures. They also prevent the beam itself (its free end) from twisting. Therefore, the technology of studding (installation of a rod) is an indispensable element in the construction of any building from a profiled beam of natural moisture.

In that profiled timber houses- this is a modern, reliable and profitable way of building housing, 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 timber houses possible indefinitely. However, in this article we have set ourselves the task of telling you about one drawback of wooden (including timber) buildings and ways to neutralize this drawback. We will talk about the natural moisture content of wood, and the problems associated with it.

Timber houses: the crux of the problem

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

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

Shrinkage degree profiled timber houses may depend on many factors.

First of all, it is the level of humidity and the variety wooden 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.

Royki: protection of timber houses from deformation and shrinkage

In order to neutralize the negative impact on your log house of the problem described above, two complementary methods are used:

• Used to build a house profiled timber, which has undergone additional industrial drying. The percentage of moisture in such a bar is not more than 20. As a result, there is less shrinkage and shrinkage of an already finished house.
• Used for 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 invite you to talk in more detail.

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

Roiki help to effectively solve the problem of deformation of window and door openings. If we just saw an opening in the wall from a beam, and then install a window or a door in it, then, after a while, the drying wood will make your opening too large, and the door frame or window frame will simply fall out of it. To avoid such a development of events, install between the frame or door frame swarms, reducing Negative consequences shrinkage and subsidence of wood to a minimum.

How racks are installed

When installing roek for timber houses, usually the following steps are taken:

• An opening is cut in the wall of the house for a door or window, and its finishing is carried out.
• In the end part of the resulting opening, a longitudinal cut is made. The cutting depth should correspond to the height of the slats, and the length should be 6-12 cm longer than the length of the used beams for timber houses. This will give room for the shrink gap.
• After that beams for wooden houses are installed in the prepared cuts, and door or window frames are already attached to them. A gap is also left (about 5 cm wide) 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 the safe shrinkage of the house.

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

Roiki

Construction of wooden houses is gaining more and more popularity. More and more people choose ecological housing and move out of town. About all the benefits wooden house many articles have been written, and they are all correct. The disadvantages are not so numerous and, rather, not even disadvantages, but the features of operation and construction.

It's no secret that a tree, natural building material tend to dry out. wooden house or glued laminated timber must 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 accurate setting of levels and gaps ensures normal opening / closing, the absence of cracks and drafts.

For modern technologies construction, shrinkage and shrinkage of a wooden house do not cause problems associated with windows and doors. With proper construction wooden, namely, in the process of preparing window and door openings, they use "swarms" - a technological element that prevents changes in the size of the opening.

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

Peculiarities of rack mounting

The installation of the racks requires compliance with some rules:

• Roika must exactly match the prepared groove.
• Installation is tight, but without rigid fixation.
• box The door or window frame is attached only to the rail.
• The upper edge of the rod should be 10-20 cm shorter than the opening.

For installation swarms it is very important to follow the last rule. lowerThe th edge should rest firmly on the floor, if it is a door, or on the lower horizontal beam of the window opening. At the same time, the top edgeswarmsmust necessarily 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.

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

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