Description

The invention relates to the field of design and construction of low-rise wooden buildings and can be used as wall elements constructed on the basis of glued lumber.

Known wooden beam or stand and a method of manufacturing such a beam or stand according to the patent for invention RU No. 2247023 (B27N 5/00, patent holder: NYUBERG Ulf, published: 02.27.2005). The known beam or stand is made entirely of wood shavings or wood chips glued under pressure and when heated, and has the form of an elongated element with a curved or curved profile.

Using a well-known beam or stand can reduce the consumption of industrial wood for construction, however, the manufacturing technology of such products is characterized by increased complexity, labor and low cost.

Known wall of the house according to the patent for invention RU No. 2168592 (E04B 2/70, patent holder: Vardapetov EA, Kozlov KV, Ratushny SG, published: 10.06.2001), ordinary corner panels of which are made without extreme racks-ribs, and the sheathing of ordinary panels occupies their entire surface, and the corner ones - protrude beyond the bounds of the panel frameworks by an amount equal to the thickness of the latter.

Such a design allows to increase the tightness and insulating qualities of the panels, but is characterized by insufficient bearing capacity of the wall and excessive consumption of the original lumber.

Known is the composite building element of the wall according to the patent for invention RU No. 2394131 (E04B 1/10, patent holder: HUNDEGTER Hans, published: 07/10/2010), containing several layers of boards following each other in height, the latter having different directions, and the boards are of the same layer connected to the boards of the adjacent layer using mounting pins.

This design is ensured through a fairly simple technology for the preparation of the initial lumber and quick installation of the wall, however, the requirements for its strength and bearing capacity in the required volume are not fully met.

Closest to the proposed design for the achieved technical result is a device for erecting a wall according to the invention patent RU No. 2417288 (E04B 1/10, patent holder: Tsarev P.E., published: 04.24.2011), including external and internal long and short lamellas fastened with pins and adhesive joints. With the help of such a device, the best and cost-effective use of substandard wood is provided, however, the required stiffness, strength and bearing capacity are also not provided.

The technical task of the claimed design is its unification, as well as improving the quality of construction work and operational performance.

This result is achieved by the fact that in the construction of a wooden wall rack, including external and internal long and short lamellas fastened with adhesive joints, the rack itself is given the shape of an I-beam profile, formed from two Tauri symmetrically located relative to the vertical axis of the rack, consisting of external lateral lamellas-shelves which are joined with them by lamellas-walls and integrating the whole structure into a single whole of internal lamellas-stiffeners installed horizontally and (or) at an angle of 45 ° to the horizontal in a single order adjoining the front or rear side of the walls, parallel and opposite to each other, adjoining both the front and rear sides of the walls, either in a checkerboard pattern, or with alternating arrangement of both horizontal and inclined stiffeners, and the shelf racks, used for the construction of two opposite walls of a rectangular building plan, made with lower mounting ledges, as well as the walls of the racks used for the construction of two other walls of the building. In addition, boards and (or) plywood are used as the initial sawn timber for the manufacture of all types of lamella rack elements, and in addition to adhesive joints, pins, screws and staples.

In this case, the long lamellas are, for example, the side flanges and walls of the Tauri, and the internal short lamellas are the stiffeners of the racks.

The design of the invention is shown in the drawings, where Fig. 1 shows a front view of a rack with lamellas-shelves equipped with mounting tabs, and its sectional view along section II, Fig. 2 is a front view of a rack with lamellas-walls, also equipped mounting tabs, figure 3 is a top view of two adjacent racks, figure 4 is a variant of the system of lamellae-ribs installed horizontally and obliquely at an angle of 45 ° to the horizontal, and in figure 5 - six options for the device stiffeners. As can be seen from figures 1, 2, 3 and 4, the claimed design has two types of wall racks, namely racks with shelves, equipped with mounting tabs from the bottom, and racks with walls provided with the same protrusions. Figure 5 presents six options for the location of the internal struts of stiffeners, including: a - with single ribs mounted only on one side of the walls, b - pairwise parallel ribs, c - staggered ribs, d - horizontal ribs, d - ribs inclined at an angle of 45 ° to the horizontal, and e - using both horizontal and inclined stiffeners. In addition, variant a ′ can also be applied, which provides for the installation of stiffeners also on one side of the walls, but on the side opposite to the side adopted in variant a ′ (variant a ′ is not shown in the drawings). Figure 4 illustrates in detail a fragment of the rack, made according to option e.

Thus, according to the digital description accompanying these drawings, each rack consists of a left shelf (1), a left wall (2), a first group (3) of horizontal and a second group (4) stiffeners, arranged, for example, in a checkerboard pattern, the right shelf (5), the cavity (6) between the walls (2, 7), the right wall (7), the mounting protrusions (8, 9), which are extensions of the shelves (1, 5), and the walls (2, 7), and stiffeners (10) also inclined at an angle of 45 ° to the horizon. In addition, in FIGS. 2, 3 and 4, with the help of lettering, the names of the main parameters of the claimed design are indicated, expressed in millimeters, namely: A is the width of the shelves (1, 5), B is the width of the walls (2, 7), C is the distance between adjacent walls (2, 7), D is the length of the horizontal stiffeners (10), E is the length of the inclined stiffeners (10), F is the pitch between the horizontal stiffeners (3. 4), staggered, and G - step between adjacent racks. And since the present invention is intended for a series of low-rise wooden buildings with overall standard sizes 5 × 5, 5 × 6, 5 × 7, 5 × 8, 6 × 6 ... 13 × 13, 13 × 14, 13 × 15, 14 × 14, 14 × 15, 15 × 15 m, with 54 options, then to unify the main parameters of the proposed design of the racks, their calculated values are summarized in the general table:

A 70 96 122 148 174 200 26 B 35 48 61 74 87 one hundred 13 C 130 144 158 172 186 200 fourteen B 35 48 61 74 87 one hundred 13 D 200 240 280 320 360 400 40 E 283 340 396 453 509 566 - F 500 550 600 650 700 750 fifty G 500 560 620 680 740 800 60

where A is the width of the shelf, B is the width of the wall, C is the distance between adjacent walls, D is the length of the horizontal stiffeners, E is the length of the inclined stiffeners, F is the pitch between the horizontal stiffeners staggered, G is the pitch between the uprights . The last column of the table shows the increment size of each rack parameter with a sequential increase in the serial dimensions of the building being erected.
