BUILDING ELEMENT AND BUILDING DESIGN ON ITS BASIS

The utility model relates to the field of ground construction, specifically to the elements of building structures.

The leading direction of effective construction is currently the use of lightweight metal structures in buildings and structures of industrial, civil, agricultural and other purposes.

Reducing the metal consumption of buildings and metal structures used in construction is achieved through new structural forms, the use of profiles (bent, bent-welded, perforated, corrugated, low-alloy sheet steel with increased strength), rolled sheets, effective materials for load-bearing and enclosing structures.

Known beam building elements made in the form of a beam of I-beam, channel, Z-shaped, box-shaped and other types of cross-section.

The closest analogue of the claimed utility model is the “Box-section building element (Utility Model Certificate No. 7436 for application No. 97118917 / 2C dated 11/17/97; RU PMPO No. 8 08/16/98), including a pair of congruent interconnected bent zigzag metal profiles of the Shaped form with bends at the ends, in the shelves of which longitudinal ridges of triangular section are formed, the thickness of the ridges exceeds the thickness of the profile and fasteners are installed in the ridges, for example, in the form of screws, rivets or self-tapping screws, with which echivaetsya mutual articulation couples of profiles to form an element, the outer contour of which has a cross-sectional I-beam shape.

The objective of the claimed utility model is the development of a building element and building structure based on it, meeting the following technical requirements:

manufacturability and versatility in use;

increase in resistance to bending;

decrease in metal consumption and weight;

the possibility of articulation with the formation of building structures of various applications;

The task is solved by the fact that

the element is made in the form of a profile of a C-shaped section with

ends bent towards each other;

ledges and corrugations are made in the side wall of the profile;

bent ends, ledges and corrugations form longitudinal stiffeners of the element, increasing bending resistance;

ledges and corrugations are made with a step 1/5 of the length of the side wall, which allows you to include the entire section of the profile element and ensure sufficient strength characteristics of the element (bearing capacity) without increasing its cross-sectional area and thickness;

the length of the side is 4.0-4.5 the length of the shelf section of the profile;

mating parts of the profile (upper and lower shelves, side and bends of the ends) are made at an angle of 90 °, the bends of the ends are made of the same width.

The building structure includes two building elements, turned to each other, combined with the respective curved ends and rigidly fastened together to form a box-shaped profile structure with stiffeners along the height of the profile.

The building structure includes two building elements, turned to each other, combined with the sides and rigidly bonded to each other with the formation of the profile structure of the I-section with stiffeners along the height of the profile.

Figure 1,2,3 shows a General view of the building element and building structures of the box and I-sections on its basis, where:

1- upper and lower shelves;

2- side;

3- bends at the ends of the shelves;

4- ledges;

5-corrugation;

6-building element;

7-welding.

The building element (figure 1) is made in the form of a profile of a Shaped shape with bends at the ends (3), directed towards each other. The upper and lower shelves (1), the side (2) and the bends at the ends (3) mate with each other at an angle. The length of the side is 4.0-4.5 the length of the shelf. Rectangular conjugation of profile elements form longitudinal stiffeners of the building element.

The side of the profile in the central part is made with a recess inward, forming ledges. Corrugations (5) having a section in the form of a circular arc are made in the recess. The ledges (4) and corrugations (5) are located in increments of 1/5 of the length of the side, the height of the ledges and the depth of the corrugations exceed the thickness of the profile, and the bends of the ends are made of the same length.

The box-shaped building construction (Fig. ;; made of two building elements b, turned to each other / combined with the corresponding bends and rigidly fastened to each other on the outside of the bending ribs with the formation of the box-section structure with stiffening ribs along the height of the profile. Rigid fastening of structural elements made by welding 7.

The technology for assembling a box-shaped building construction is as follows. Two building elements (6) turn to each other with bends of the ends and combine their respective planes. After that, they firmly connect both

parts of the structure by welding (7) along the outer part of the ribs of adjacent bends.

The building structure of the I-section (Fig.) Is made of two building elements 6, turned to each other, aligned with the sides and rigidly bonded to each other on the outside of the adjacent ribs with the formation of the profile structure of the I-section with stiffeners along the height of the profile. Rigid fastening of structural elements is performed by welding 7.

The technology for assembling a building structure of an I-section is as follows. Two building elements (6) are turned to each other by the sides and combine their respective planes. After that, both parts of the structure are rigidly connected by welding (7) along the outer part of adjacent ribs.

The building element is made of sheet material with a thickness of 1.5-2.5 mm on existing rolling equipment.

The building element is made of steel grades C235 and C345 according to GOST 27772-88, which provides a sufficiently high: e strength characteristics of the product; for example, the bearing capacity of this building profile allows for the use in construction of multi-hollow prestressed floors made of heavy concrete of grades 400, 450, 500 (strength class ВЗО, В35, В40).

The stiffeners in the claimed design solution of the element, formed by rectangular mates of its sides and bends of the ends and ledges and corrugations made in the lateral side, can significantly increase bending resistance compared to a conventional C-shaped profile. With a material thickness of 1.5-2.5 mm, the moments of inertia of the element along two axes are Jx 276-461, 2-23.9 the moment of inertia during torsion is 33.4-181.5, the radii of inertia are, respectively, 6 and, 79-l, 67 cm.

modern power tool and easily connects with self-tapping screws. The fastening of the element and the mutual connection of the elements can be performed using bolts, metal screws, rivets; semi-automatic welding in a carbon dioxide medium can be used for a rigid connection of elements.
