WALL PANEL

The useful model belongs to the field of building structures, namely to wall panels with a wooden frame and will find primary use in low-rise wooden housing construction.

Panels with a wooden frame, cladding and thermal insulation are known (K. G. Goetz and others. Atlas of wooden structures, M., Stroyizdat, 1985, p. 2; p: 4,; 6I-263).

The frame is made of racks - boards of standard sections, for example 5 X 10 cm, located along the panel with frequent steps of dimensions in height and thickness of the panel.

The design flaws are its bulkiness and high consumption of structural wood.

Closest to the claimed and selected as a prototype is the device of wooden sheathing walls and partitions according to the patent of the USSR V.D. Romanov No. I89I8, Cl. Е04В2 / 80, priority 28.11.82g.

The device comprises a wooden frame made of rigidly connected sertical struts arranged in increments along the panel, and crossbars installed staggered between them. There is a vertical partition made of plywood, etc. sheet material, playing the role of thermal insulation. It is possible to use for partitioning sheet fire-resistant material.

The assembly of crossbars staggered by their end and side surfaces with uprights is carried out in two mutually perpendicular planes, which complicates and complicates the assembly. rod) or from sheet fire-resistant material is installed between the redids of racks and crossbars. The insulation is fixed in small areas at ftt0: Tax of the contact of the crossbars installed in a checkerboard pattern and fixed with their midpoints to the uprights. Such a Hev design provides a dense uniform fit of the thermal insulation along its entire plane and ends, which does not exclude possible air circulation, and therefore leads to a decrease in heat transfer resistance. The objective of the proposed technical solution is to create a simple design of the wall panel with a wooden supporting frame, made with the least labor costs, saving structural wood and thermal insulation, with increased resistance to heat transfer. To solve this problem, in a wall panel containing a wooden frame of vertical racks installed in increments along the panel and staggered between them in a checkerboard pattern, and thermal insulation, according to a utility model, the racks are arranged in a row with a gap between them across the panel, and crossbars are placed in the gap between adjacent racks of two adjacent transverse rows with the possibility of fixing along their lateral vertical planes. Soft mats, for example, made of inorganic fibers, installed between the lateral vertical planes of the crossbars and racks, are used as thermal insulation, while the total thickness of the two mats is greater than the gap between the racks, but less than twice its size. The installation of crossbars in the gap between adjacent racks of two adjacent transverse rows and fixing them with lateral vertical planes to the racks makes it possible to assemble the panel elements in one plane, which allows to automate the assembly process and reduce its complexity.

The use as thermal insulation of soft mats made of inorganic fibers installed at the points of contact between the crossbars and racks allows you to: reduce compression of the insulation along its lateral vertical planes,

And the use of mats with a drying thickness of one size larger than the gap between the uprights, but less than twice its size ensures the creation of the necessary closed air layers and eliminates air circulation between them, which increases the resistance to heat transfer.

The claimed technical solution has a difference from the prototype, i.e. meets the criterion of novelty and does not follow explicitly from the studied prior art. The proposed utility model may find application in industry, i.e. characterized by industrial applicability.

The essence of the claimed technical solution is illustrated by drawings, where in Fig. 1 a wall panel is shown, a longitudinal section, in Fig. 2 is a front view of the panel, in Fig. 3 is a section A-A in Fig. 2.

The proposed wall panel includes vertical racks: (1) installed with a gap (2) relative to each other across the panel and with a step (3) along the panel. The crossbars (4) are installed in the gaps (2) between adjacent posts (I) of two adjacent transverse rows and are fixed by lateral vertical planes to the posts (I). The crossbars (4) are staggered along the height with uniform reinforcement of the uprights (I). The panel is insulated (5). As thermal insulation can be applied to well-known thermal insulation materials - bulk, sheet, fluid. The preferred option is soft mats, such as inorganic fibers.

The mats are pressed along the vertical planes between the uprights (I) and the crossbars (4), partially deformed in the gap (2) and form closed air spaces (6) in the spaces between the rows of uprights. (I) and crossbars (4).

The outer skin (/) can be composed of sheets joined on the uprights (I) by known methods.

P2YOM§2.ё2ййЕё2ё25,2-, 1йЦ25ЙЁё25

Vertical posts (I) and crossbars (4) are made of 40 X 40 rails. The racks are installed along the length of the panel with a step (3) f 1 m. The number of posts (I) in the transverse row is 3. The posts (I) form 2 gaps in which the crossbars (4) are installed in a checkerboard pattern and

fixed on vertical planes by methods known in the art, for example, nailing. .:,:,

Between the uprights (I) and crossbars (4) soft mats of inorganic fibers, for example, fiberglass with a thickness of :: ZOmm, are installed, which form air-sealed layers together with the panel skin (7), the mats are deformed by 20 mm in the gaps between the uprights (33), This ensures that the panel is sealed at the end surfaces and creates closed air spaces inside the panel.

This panel with a thickness of 200 mm has a mass of 12 kg / m, heat transfer resistance cg 5m ° C / W.

Sheathing, panels are made of wood.

The use of racks installed with a gap relative to each other increases the moment of inertia of the cross-section of the racks and, as a result, increases their bearing capacity.

The use of relatively small building elements of the same type, for example battens, creates a lightweight structure (discharged frame) with spatial rigidity, provides savings for structural wood, which is saved by increasing the moment of inertia in the remote panel by 50. The thermal insulation in the proposed panel is uniformly clamped across the entire plane. It excludes sagging and slipping. This ensures the durability of the element, and therefore the economy of thermal insulation. Since part of the thermal resistance is provided by air gaps, the savings in thermal insulation consumption are 30-60 /. The increased thermal properties of such a panel will allow the construction of energy-efficient buildings with reduced heating costs - schools, kindergartens and, most of all, permanent residential buildings.
