Description

The invention relates to collapsible structures and can be used in vaulted roofs of buildings and structures that are rectangular in plan.

The purpose of the invention is to reduce material consumption and simplify installation.

On figure 1 shows the coating, front view; figure 2 - section aa in figure 1 | in FIG. 3, the connection of the plates between them is articulated with the possibility of their rigid fixation; figure 4 - section bb in fig.Z; on fig.Z - section bb In fig.Z; figure 6 - coating axonometric; 7 - the same, folded.

The foldable section of the vaulted cover includes the upper rigid one with, made of plates 1 interconnected pivotally at the lower faces of the plates at an angle to one another, and two branch-like flexible lower ones with 3, connected to the upper side by braces 4. Each plate 1 composed of half-plates 5 and 6, clamped in the hinges 2 of the upper cus, one of which 5 is made with protrusions 7 and the other 6 with the corresponding grooves 8, and interconnected in the hinge joints 9 with the possibility of their rigid fixation by means of a rod 10. Branches of the lower p sa located

in the planes of the side faces of the plates.

I

The sequence of installation of the folding section of the coating delivered to the object in folded form is as follows: first, plates made of half-slabs 5 and 6 are opened. In half-slab 5 there is one oval hole, and in half-slab 6 there is one round hole. After the plates have been opened, the protruding parts 7 come together in the corresponding grooves 8 and by passing through round and oval holes of the rod 10 a rigid connection of half-bridges 5 and 6 is provided. The oval shape of the holes simplifies the process of passage of the rod 10 through them

From all the expected operational loads in the elements of the top sa, only compressive forces and local bending moment from occur. directly acting loads, the lower one from 3 and bracing 4 stretched. The compressive forces occur only in the upper section and also have enclosing functions. Stretching forces are always transmitted to flexible braces, which is explained by the crescent-shaped flexible lower arms relative to the upper force, in which the tension of the lower flexible nodes move downwards and resists the flexible braces by their tension. The tension forces of the braces exceed the compressive force that usually transmits to some flexible braces from the nodes of the upper belt. The geometries of the upper sa sa to the lower ones flexible in themselves also result in the occurrence of uniform compressive and stretching forces in both the upper and lower lines and the indisputability of the coating.
