The invention relates to the field of construction and can be used in construction during the construction of low-rise heated and unheated buildings of wood and wood-based materials for various purposes (residential, public, industrial and so on).

Widely known wall design wooden buildings construction made of logs or bars. Connection logs or planks at the height of the implement various bed seams and corners, pair of inner and outer walls they are using insertions, locks, a pair of dovetail" etc. (Stefko I., Reinprecht L. Modern wood construction: cottages, gazebos, pergolas. - M.: Publishing house "Niola Press, 2006, p.27-28, Il. 2.1-2.5). Significant disadvantages of such wall constructions are:

- too much manual labor manufacturing hub connection logs or bars, their building to the implementation of complex insertions and caulking of the seams;

- the need for high-quality work of a highly qualified workforce;

- a large volume of construction works;

- difficulty providing the required construction standards degree of thermal insulation of external walls.

Closest to the technical essence and the achieved effect is a constructive solution of the mouth of the STS wall of the calibrated logs, solid or glued laminated timber factory, which, in addition to the internal log or block the base layer, are also included to improve the insulating ability of the external walls of the wooden elements of the framework under the wall sheathing, vapor barrier, exterior wall sheathing boards, mineral wool insulation is located between the vertical surface of the cobbled part of the wall and the plank siding (M.M. Gapeev, IGOR Guskov, L.K. Ermolenko and other Structures of wood and plastics. - M.: Publishing house of the DIA, 2004, s-356, rich). Notches and cutting the logs or bars in the places of their mates carry out industrially on a pre-applied markings on the respective machines. The required degree of thermal insulation of external walls is easily achieved with a corresponding effective thickness of mineral wool insulation. However, this known design solution has the following significant drawbacks.

1. Great complexity and installation works due to the presence of numerous boards, the need for insulating the horizontal bed joints and quite complex nodal pair.

2. The lack of advantages of modular high-speed Assembly.

3. The execution of the designs node pair and abutting on woodworking machines does not provide the necessary density of joints and is responsible, not eliminates heat loss and air flow through the seams due to known when machining tolerances.

4. The limited degree of spatial rigidity of the building due to the use of linear and planar structures using compliant connections between them.

The technical result obtained from the use of the invention is the simplification of the structural scheme of the wall barrier, increasing its spatial rigidity, reliability and reduce installation complexity.

The problem is solved due to the fact that wall structure consisting of an inner supporting layer, the frame under the wall sheathing, vapor barrier, shields, exterior cladding and insulation, the inner supporting layer made of prefabricated laminated blocks horizontal cutting, fitting in the corners and abutting the inner walls to the outer walls by using laminated l-shaped and T-shaped inserts, with prefabricated laminated blocks and paste, sliced on only one side face side of the internal spaces, which are connected to each other by the height of the wall structure on the pins, affixed to the bottom face of each laminated block or insert in their manufacture and in the underlying socket elements mounted when mounting the wall structure.

In addition, the proposed wall to the reconstruction insulation of external walls are made by foaming of the adhesive composition between the panels of the outer casing, laminated blocks and inserts as they are tiered installation, when this adhesive composition is adjacent' to Neutrogena the side faces of the laminated blocks and inserts, as well as to the inner surfaces of the panels of the outer shell.

The invention is illustrated in the drawing, in which figure 1 shows the wall construction with laminated blocks DB, G-shaped VG and T-shaped W inserts; figure 2 - structure laminated block DB; figure 3 - design of the G-shaped insert VG; figure 4 - design of the T-shaped insert W; figure 5 - pair laminated blocks DB with inserts VG and W using the connection ridge in the groove" (node "a" and "B" from figure 1); figure 6 - pair laminated blocks DB with inserts VG and W using plywood strips (nodes "a" and "B" from figure 1, option); figure 7 is a section through a wall showing the insulation and shield the outer lining.

The wall construction includes an inner supporting layer 1, frame beneath the hull walls 2, barrier 3, panels exterior cladding 4 and the heater 5. The inner supporting layer 1 is made of prefabricated laminated blocks 6 horizontal cutting, fitting in the corners and abutting the inner walls to the outer walls by using laminated l-shaped 7 and T-shaped 8 inserts, with prefabricated laminated blocks 6 horizontal cutting, and l-shaped 7 and T-about asnie 8 insert external walls otstraivayut only on one face side of the internal space and connected to each other by the height of the wall structure pasted on the bottom side of each laminated block 6 horizontal cutting and laminated l-shaped 7 and T-shaped 8 inserts the pins 9, which is during the installation zamonolichivajut into the slots 10 of the underlying mounted elements. Insulation wall structure made by foaming of the adhesive composition between the panels of the outer shell 4 and the laminated blocks 6 horizontal cutting or laminated with l-shaped 7 and T-shaped 8 inserts as they are tiered installation with simultaneous bonding to them. Laminated l-shaped 7 and T-shaped 8 inserts can be made with angles other than right angles, depending on the configuration of the external walls.

We offer wall structure is assembled in the following order. Traditional production lines of factories glued wooden structures made according to the design dimensions of the rectangular laminated blocks 6, laminated l-shaped 7 and the T-bolt 8 is inserted. On the upper faces of manufactured items 6, 7 and 8 on the put markings, either drill socket 10 under the pins 9 and the bottom face is made of elements 6, 7 and 8 glue a pin 9 also applied in advance markup, with pins 9 and slot 10 is disposed on the same vertical line. Perform the redoubt one of the side faces of the laminated blocks 6, laminated l-shaped 7 and T-shaped 8 inserts, which will be located outside the s interior. In a pre-made Foundation on the topside also provide nest step which is step pins 9. Immediately before installation laminated blocks 6, laminated l-shaped 7 and T-shaped 8 inserts the lower tier of nests in the basement filled adhesive composition. Perform the installation of all elements of the first tier of the internal base layer 1: laminated blocks 6, laminated l-shaped 7 and T-shaped 8 inserts, utaplivaja pins 10 in the nests of the Foundation, how do you fix all the assembled elements in a design position. Connections laminated blocks with 6 laminated with l-shaped 7 and T-shaped 8 insertions performed using simple and well-known techniques, for example, "the ridge in the groove"plywood strips, notched adhesive joints, etc. Put in the design position shields the outer skin 4, setting them at the required distance from the outer face of the bearing layer 1 (depending on the required thickness of insulation 5). The height of the panels of the outer casing 4 is equal to the height of the inner carrier layer 1. To the inner faces of the panels of the outer casing 4 attach the vapor barrier 3. Perform heat insulation of the first tier of the exterior walls with insulation 5, placing it between the panels of the outer shell 4 and the laminated blocks of 6 or inserts 7 and 8. In the socket 10, issue is Lennie on the upper faces of the laminated blocks 6, laminated inserts the l-shaped 7 and T 8 outlines in plan pour adhesive composition and perform the installation of the second tier of the internal base layer 1, and the pin 9 is fixed in the socket 10 and there is then embedded in the cured adhesive composition. Next, the above operation is repeated, setting in accordance with the project window, door or any other necessary framing technological gaps.

Through the use of in wall structure effective heaters 5, the thickness of the laminated blocks 6, laminated inserts the l-shaped 7 and T 8 outlines in plan of the inner carrier layer 1 can be kept to a minimum, equal to 80-100 mm Production of such laminated elements may be implemented on any domestic plants glued wooden structures on traditional technologies. Other geometrical dimensions of the laminated blocks 6, l-shaped 7 and T-shaped 8 insertions determine when designing horizontal and vertical layout of the premises and shall ensure the stability of the walls and the spatial immutable structures constructed object as a whole. In most cases, for example, for the construction of residential buildings, a sufficient length of blocks does not exceed 6.0 m, and the height of cross section of 1.0 m, which is technologically quite acceptable for manufacturers KD is.

In the corner junctions of the walls and at the junction of the inner walls to the outer in the proposed wall structures used laminated l-shaped 7 and the T-bolt 8 is inserted. Such a constructive method has allowed to avoid complex connections of the individual blocks together at right angles, ensuring the integrity of these sites. The height of the laminated inserts 7 and 8 are assigned equal to the height connected with them laminated blocks 6. The portion of the laminated T-shaped 8 inserts, which is located on the inner side of the outer wall, is used for splicing with her transverse bearing walls or partitions, and performs the role of buttresses, ensure the sustainability of the walls, and is also used as a support for the floor beams. In addition, due to the spatial shape in plan laminated l-shaped 7 and T-shaped 8 inserts when mounting the walls, there is no need temporary arrangement mounted elements. Also laminated l-shaped insert 7, depending on the project the outlines of buildings in the plan can be executed not rectangular, but with angles other than straight, which does not cause any technical difficulties.

Connections laminated blocks 6, l-shaped 7 and T-shaped 8 insertions invited to perform on pasted in factory conditions in their lower edge of the pins 9, performed the s of reinforcing steel periodic profile. When mounting each subsequent tier of the pins 9 is slid in the slot 10 of the lower tier and zamonolichivajut them on the adhesive compositions, for example, using epoxy compounds. The depth of the insert must be at least 10 diameters of the pin 9. The diameter and shape of the slots 10 is assigned taking into account the inevitable deviations from the design dimensions and the need to place the inner surfaces of the laminated block 6, l-shaped 7 and T-shaped 8 insertions in the same vertical plane. It is proposed to place the pins 9 at the ends of the blocks 6 and inserts 7 and 8 and in their middle part, but not less than 2 m from each other. The diameter of the slots 10 to receive 10 mm larger than the diameter of the pins 9.

Along with the possible use of traditional methods of thermal insulation by means of the installation plate or rolled insulation in the inventive design serves to insulate the walls, blows adhesive composition (for example, polyurethane-based resins), filled in between the panels of the outer shell 4 and the laminated blocks of 6 or inserts 7 and 8. The foaming resin is recommended for the height of the blocks (inserts) on longline as their installation. This will fill all the leaks and to ensure prikrivanje heater 5 to the laminated blocks 6, l-shaped 7 and T-shaped 8 inserts, and panels of the outer casing 4. The quality of the gluing of the heater 5 to a surface is of 6 blocks and inserts 7 and 8 will be provided with their roughness, since these surfaces in the manufacture of laminated elements is not planed.

After all laminated blocks 6, l-shaped 7 and T-shaped 8 insertions close to each other are formed smooth wall surfaces, as the surfaces of the blocks and inserts, facing into the room, pre-processed and finished at the factory. After mounting, wall cladding requires only cosmetic improvement of the internal surfaces of the walls.

Thus, in comparison with the prototype, the proposed wall design allows to simplify the design concept of wall cladding, to increase its rigidity, reliability and reduce the complexity of installation 25...30%.
