Building structure

FIELD: construction.

SUBSTANCE: building structure includes straight-line elements attached to each other and made from a glued plywood profile containing walls made from plywood and shelves made from bars fixed on the wall along longitudinal edges. There have been used three straight-line elements that are fixed so that an equilateral triangle is formed in a plan view; the shelves of straight-line elements face each other.

EFFECT: increasing carrying capacity of long glued plywood building structures owing to forming a stiff load-carrying element at their operation as part of panels, which is related to perception and redistribution of vertical loads.

The invention relates to the construction and can be used in low-rise construction for the construction of wooden houses and outbuildings.

Known for building construction, comprising a wall, made in the form of strips of plywood and shelves made in the form of bars, mounted on the wall, along the longitudinal edges of the strip (see THE 5366-010-04779210-2000 "Beams cleanery I-floor and attic floor with belts from separate plates developed state Dalnii).

This design is effective only when the device of the floors is comparatively small extent, since the formation of elongated beams (the joining of separate beams supplied by the vendor) is difficult due to the low strength of the joint. In addition, increasing the bearing capacity of such a profile may in fact due to the use of thicker plywood, the production of which is not mastered, and therefore when using existing range of materials unreal.

Also known construction including bonded to each other rectilinear elements, made of cleaning profile containing walls made of plywood and shelves made of bars attached to the wall along the longitudinal edges (see RU # 46786, EC 3/12, 2005).

The disadvantage of this those the technical solutions the inability to use design at high loads because the load-carrying capacity of the structure is determined by the Flexural strength of the plywood plates.

Solved technical problem - the possibility of the formation of stiff (frame) element, which leads to the increase of carrying capacity of long cleaninig building structures.

The technical result obtained by the solution of the problem, expressed in the increase in the carrying capacity of long cleaninig building structures due to the formation of stiff (frame) element in their "work" in the composition of the panels associated with perception and transfer the vertical loads. Forming an equilateral triangle allows to minimize the number of sizes of frame elements necessary for the formation of a number of parallel upper and lower edges, from which it is easy to form the panel.

To solve the task of building design, including bonded to each other rectilinear elements, made of cleaning profile containing walls made of plywood and shelves made of bars attached to the wall along the longitudinal edges, characterized in that used three rectilinear element, which is bonded with education is the Finance in terms of an equilateral triangle, this shelf line elements facing each other.

Comparative analysis of the characteristics of the claimed solution with the characteristics of the prototype and analogues demonstrates compliance of the claimed solution to the criterion "novelty".

The characteristics of the characterizing portion of the claims, solves the following functional tasks.

Signs "...used three rectilinear element, which is bonded with education in terms of an equilateral triangle..." provide the possibility of forming a stiff (frame) element, thus forming an equilateral triangle allows to minimize the number of sizes of frame elements necessary for the formation of a number of parallel upper and lower edges, from which it is easy to form the panel.

Signs "...regiments of the line elements facing each other..." provide the opportunity planar contact building structures with each other (when they "work" in the composition of the panels associated with perception and transfer the vertical loads). In addition, it ensures reliable fixation of the heater in the opening of the building structure.

In the drawings shows a rectilinear elements 1, wall 2, shelf 3 and the longitudinal is romky 4 walls 2.

The building design includes bonded to each other rectilinear elements 1, with education in terms of an equilateral triangle. Straightforward elements 1 made of cleaning profile containing walls 2 and 3 shelves. For the manufacture of the walls 2 use plywood brand PSF grade not below/BB GOST 3916.1-89 thickness of 8 and 10 mm For the manufacture of shelves 3, made in the form of bars, use wood not below 2nd grade softwood (except larch) according to GOST 8486-86 with dimensions according to GOST 24454-80, with the corresponding estimated characteristics of the SNP P-25-80. Quantitative parameters of shape defects and machining (pokeronline, the deviation from parallelism of surfaces and edges, wane) should not exceed permissible for lumber 2nd grade. Through cracks appearing on the face are not allowed. Knots decayed, rotten and tobacco, as well as dead, located on the edges are not permitted.

Shelves 3 are glued to walls 2 in length along the longitudinal edges 4 of the wall 2. Then, from the thus formed line elements 1 form directly cleanery construction element, for which purpose they are placed in groups of three with education in terms of an equilateral triangle, with 3 shelves line elements 1 facing each other, stick together with each other, province is with screws.

Adhesive joints in structures should be performed on synthetic adhesives, relevant SNiP P-25-80. When this adhesive joints must meet the following requirements:

- the moisture content of the wood parts of the beams before processing protective compounds must be(12+/-3)%;

the thickness of the adhesive layers in the elements of structures shall be not more than 0.5 mm are Allowed plots of thickness up to 1 mm, if their length does not exceed 100 mm, and the distance between them is not less than ten times the length of these interlayers;

- not glued areas are not allowed.

The finished design, if necessary, subjected to a protective and/or decorative treatment to protect them from moisture, biodeterioration, combustion, and chemical corrosion, as well as giving them the necessary aesthetic appearance. These works are carried out on the manufacturer. Protection as possible from one, and from these effects, which is governed by the operating conditions of the structures.

Building design, including bonded to each other rectilinear elements, made of cleaning profile containing walls made of plywood and shelves made of bars attached to the wall along the longitudinal edges, characterized in that used three rectilinear element, which is bonded with the formation of vplane an equilateral triangle, this shelf line elements facing each other.
