Description

(54) FOLDING WELDING CONSTRUCTION The invention relates to the construction and can be used in the construction of structures for various purposes. A known cross-grid covering consisting of half-folding trusses of one direction, hingedly connected to elements of folding trusses of another direction 1. The drawbacks of this lattice cover are considerable transport dimensions and unavoidable labor costs on the construction site for installing and securing horizontal connections. Also known is the folding in both directions of the supporting structure of the coating, consisting of intersecting trusses formed by X-shaped braces and themselves, and the braces are jointly connected to each other in the center and at the ends 2. The disadvantage of this design is the additional labor costs on the construction site installation and mounting on owls farms. Closest to the present invention is a folding support structure of the coating, including rods of the upper and lower belts and braces, pivotally interconnected in knots with the formation of pyramids with square bases of lsh fSl. The disadvantage of this design is the excessive labor costs on the installation of the installation and fastening of the rods. The purpose of the invention is to simplify installation. This goal is achieved by the fact that the folding supporting structure of the coating, including the rods of the upper and lower cores and braces, hingedly connected to each other at the nodes with the formation of pyramids with square bases, is provided with self-centering elements mounted at the nodes at the hinged joints and braces with the ability to interact with each other, with the articulated joints of the braces having self-centering elements located on the outer side, and the rods of the lower planes are inclined from these arnier compounds. Self-centering elements are located in every second node of the structure. In addition, the folding of the supporting structure of the coating is provided with racks attached to the nodes and additional braces, with the upper ends of all the braces hinged at the nodes of the upper belt odd from the edges of the structure, and the lower ends of the additional braces attached at each second node of the lower owls, odd from the edges of the structure, with self-centering elements, while the lower ends of the braces are attached to each second node of the lower strip, odd from the edges of the structure, with self-centering elements, with The bottom ends of the braces are attached in each BTOfJOM node of the lower strip, even from the edges of the structure, and the rod n-1 of the lower strip is mounted with a slope from the bottom of the diagonal braces.

The folding structure of the coating includes the rods of the upper and lower pockets 1 and 2 and braces 3, fastened between themselves in the nodes by hinged joints 4-6 with the formation of square pyramids. grounds. The articulated joints (4) are combined into braces. 3 and the rods 1 or 2, the hinge joints 5 unite the rods along the i or 2, and the hinge joints 6 unite the braces 3. The hinge joints 5 and 6 are provided with self-centering elements 7 and 8, made for example in the form of quatrefoils with bent trapezoidal petals (.fig. 13 and 14), with the possibility of interaction with each other, and are located in each second node

designs. In the working position, the hinge joints 5 and 6 are fixed to each other in the construction nodes by bolts 9, while the hinge joints 6 are located on the outer side of the rods along the owls 1 and 2, and the rods of the lower streaks 2 are located with a slope from these swivel joints.

In addition, folding, and with the supporting structure of the coating (Fig. 8-12) can be equipped with racks 10, additional braces. And, and each rod of the upper but sa I can be made of two elements 12 fixed by a hinge 13, Each rod of the lower CA 2 is made up of two elemen tions 14, fastened by an interconnecting connection 15 and about. In this case, the upper ends of the braces 3 il are fixed by hinged joints 16 at the nodes to the hinged joints 2, 13, 14 and 6. The lower ends of the additional braces I i are fixed in pairs between each other by the hinge joints 5, odd from the edges of the structure, and the lower ends of the braces 3 are fixed — between themselves (four) by hinged joints 6, located under the hinged joints — 5 in every second node of the lower parts 2, even from the edges of the structure. The hinge joints 17 are equipped with self-centering elements 8 with the possibility of interaction in the nodes with the self-centering elements 7 of the hinge connections 5, and the elements 14 of the lower bars of the lower belt are installed with a corner from these nodes. All the hinged zeno solenoids ensure the rotation of the rods by owls 1 and 2 and diagonals 3 and i 1 in a strictly vertical plane. Bolts 18 and spacer tubes 19 can be used as hinges, and rollers 20 as the undercarriage for expanding | -;

In the transport position, the structure also has the form of a compact package of hinged rods. At the construction site, the package is stretched horizontally behind two opposing parts, for example, until full unfolding, when the rods of the top land 1 are in a strictly horizontal position. At the same time, the hinged connections 1; e1sh 5 are tightly adjacent to the hinge fiM connection 6 and 17 due to the interaction of their self-centering elements 7 and 8, which prevent horizontal displacement of the hinged connections relative to each other.

The proposed technical solution gives a new property to the supporting structures of the coating, assembled from rigid elements to the stage of full factory readiness, since after they are deployed on the construction site, no additional panels are required.

The expected annual economic effect from the use of the proposed construction is 200 thousand rubles.

The proposed design can be used in the construction of various structures, especially in remote and underdeveloped areas.
