Known bearing construction item box section formed by the profile elements and covering each other regiments with the limb ends (GB patent N 2288419, class E 04 C 3/07, 1995).

The disadvantage of this design is its lack of rigidity and reliability.

Known bearing construction element consisting of shovnyh profiles with sochlenennykh sides of the ridge and the limb placed in each other during Assembly of the construction element (FR patent N 2641812, class E 04 C 3/07, 1990 ).

The disadvantage of this design is its lack of bearing capacity under vertical loads.

The closest in technical essence and the achieved result to the construction element according to the alleged invention is a construction element box section containing a pair of congruent vzaimootmenyaemy bent shovnyh profiles, the ends of each of which are shaped limb wound in respective form sections of a different profile Panie functionality of this design, which can only be used as a beam element.

The technical result is to expand the functional capabilities of the construction element shaped by increasing the carrying capacity building element, including bending loads in different directions and places of application of loads, reduction of metal construction elements, as well as the increasing tightness of the structure.

The technical result is achieved due to the fact that in the construction element box section containing a pair of congruent vzaimootmenyaemy bent shovnyh profiles, the ends of each of which are shaped limb wound in respective form sections of a different profile pairs, the outer contour in cross section has dataroaming shape and formed profiles C-shape with otegami at the ends facing each other, and with shelves, covering the entire length of the shelf another profile pairs, and the walls of each C-shaped profile in the junction shelves have convex sections, the corresponding figure for the limb ends of the other curved profile pairs, with shelves in a C-shaped profiles can be formed of a CR is whether, for example, in the form of screws, rivets or screws-self-tapping screws, and the depth of the ridge shelves profile is greater than the thickness of the profile, and the limb made at one end of the C-shaped profile that is designed for embracing the convex section of another profile pairs, may exceed the length of the limb the other end of the same profile, intended for placement in the convex area of a different profile, and the length of the sections of the adjunction C-shaped profiles is 2,5 - 3,5 width of this element, and in the walls of the C-shaped profile formed holes or notching, for example, round holes 12-24 mm

The technical result is achieved by increasing the rigidity of the construction element due to the formation of a closed box-like element, as well as accurate and reliable fixing in position and relative to each other vzaimootmenyaemy C-shaped profiles, which tightly embrace each other at the expense of existing limb, the ridge convex sections in contact with the limb.

The invention is illustrated by drawings, which shows:

in Fig. 1 is a cross section of the construction element,

in Fig. 2 is a cross-section of the C-shaped profile,

in Fig. 3 - scheme of the Assembly building is congruent vzaimootmenyaemy bent shovnyh profiles 1 and 2 C-shape with facing each other figured limb at the ends.

Bent C-shaped profile 1 is made with the limb 3 and 4, and the bent C-shaped profile 2 has a limb 5 and 6.

C-shaped profiles when connected form a construction element, the outer contour of which in cross section has dataroaming form due to the fact that the shelves 7 one profile 1 covered shelves 8 different profile. And on one side of the path of the regiment 7 profile 1 is covered by a shelf 8 profile 2 and is located on the inside of it, and on the other hand (opposite) side of the circuit regiment 7 profile 1 covers the shelf 8 profile 2 from the outside, and a shelf 8 is located inside of the shelf 7. Vzaimosohranenii and fixed relative to each other due to the limb 3,4,5,6 shelves C-shaped profiles form a shelf circuit 9 and 10 and walls 11 and 12 of the C-shaped profiles, separated from each other, form a wall of the box section of the construction element, the contour of which has dataroaming form. Wall 11 of the profile 1 in the junction of shelves 7 are convex sections 13 and 14, corresponding in shape curly limb 5 and 6 all of the other C-shaped profile 2.

Wall 12 of profile 2 at the junction of the shelves 8 are convex sections 15 and 16, corresponding in shape limb figure 3 and 4 the ends of the C-shaped lei relative to each other.

In the shelves 7 and 8 profiles 1 and 2 are formed of longitudinal ridges 17 of triangular cross section, which are the ribs of the box-shaped building element and provide an additional means of fixation C-shaped elements relative to each other. These ridges can be installed fasteners, such as screws, rivets or screws-self-tapping screws (not shown) that reinforce the fixation of C-shaped elements relative to each other. The ridge when installing fasteners serve as guides for accurate placement and reduce the local voltage profile arising from the drilled holes. The presence of ridge contributes to the reduction of the axial components of the load, resulting in twisting of the construction element. The depth of Sagov 27 "h shelf profile is greater than the thickness profile of "d".

For better fixation of the C-shaped profiles relative to each other limb 4, made at one end of the C-shaped profile 1, which covers the convex section 16 of the profile 2, exceeds the length of the limb 3 of the other end of this profile, which is located inside the convex section 15 of the profile 2.

With the same purpose, the length of the limb 5 of the profile 2, covering the convex section 13 of the profile 1, exceeds the different profiles (see Fig. 3) 2.5 - 3.5 times greater than the width "B" of the construction element, which also contributes to increasing the rigidity of the construction element and eliminates the need for additional fastening of profiles in the transverse direction.

In the walls 11 and 12 of the C-shaped profiles can be formed of a hole or perforation when using a construction element as a drainage tube.

In the walls 11 and 12 of the C-shaped profiles can be formed round hole diameter 12-24 mm for strip through them communications during installation of walls and ceilings.

Construction element box section of the C-shaped profiles are manufactured as follows.

C-shaped profiles can be obtained from a flat steel strip or strips with the application of protective coating or without it.

The tape or strip of a thickness of 0.5 to 4.5 mm sequentially passed through the cage roll forming mill, which is usually not less than 14. For roll forming mill with a total drive power 15 kW maximum width of the original piece - 200 mm Tape or strip is deformed (bent) in calibers individual strands, getting in the last stand predetermined cross-sectional shape with Rey cross-sectional profile can take other numerical values.

Construction element form a joint C-shaped profiles 1 and 2, for example, ndwiga one profile to another, as shown in Fig. 3.

When connecting the shelves 7 and 8 profiles 1 and 2 produces a rigid closed box section construction element. While the shelves of one profile over the entire length covered shelves of a different profile, with one end of each profile covers the convex section of another profile, and the other end of each profile is inside the convex part of the second profile. This joint profiles increases the rigidity of the construction element and almost doubles its carrying capacity when vertical load is perpendicular to the plane of the cross section of the construction element, and the implementation of its box-like shape reduces the intensity of building structures.

The inventive construction element box section can be used as a "profile rack" (PS), in the technology of "dry construction" can be used in thermal insulation of walls with the use of effective insulation (Styrofoam, etc).

The use of the inventive construction of the element in the construction of the ceiling allows you to increase the height of the cross is possible to keep the slab elements in mutually perpendicular directions.

Use of the claimed element as drainage or drain piping allows you to expand them to a predetermined length in the construction and arrangement of the garden plots.
