Each flat section comprises a spacer and two rods arranged at the angle to each other hingedly connected to each other and to the centre of the spacer.

Description

The invention relates to the field of construction and can be used to overlap buildings and structures, create awnings to protect against atmospheric precipitation and solar radiation, as well as to place antenna and radio transmitting installations at a certain height.

Known solutions consisting of rectilinear rods, perceiving a compressive load, and many flexible cable elements connecting individual rods in a single system [1, 2, 3]. The disadvantages of these solutions are as follows: increased deformability, inefficiency of using high-strength flexible elements, low reliability of operation, increased cost, complexity of design solutions.

To reduce deformability, rigid elements are directly connected to each other by means of hinges [4-5].

The disadvantage of the solution [4], consisting of rigid lattice modules interconnected on hinges and using a flexible cable, is the difficulty of obtaining a variety of structural forms associated with the need to use different in form modules.

Solution [5] is not reliable enough in operation, because the cable (or chain), combining the lattice modules pivotally connected to each other, is only stressed by an external load (for example, the dead weight of the structure). Impact on the design of loads of the opposite sign (for example, wind) can lead to the disconnection of the connecting cable (chain) from work due to compression and to the geometric variability of the system.

The solution [6], consisting of rigid massive (cast) modules connected end-to-end using a longitudinal tensioning cable, is not sufficiently reliable in operation due to possible slippage in the connection nodes of the modules. Also, the solution [6] is associated with a significant overspending of materials due to the massiveness of the modules used.

Closest to the proposed technical solution is a modular building structure [7], consisting of flexible belts made of cable braces, rigid longitudinal elements made of separate sections, each of which consists of a rod, and rigid struts connected to these sections, combining longitudinal elements with flexible belts. Each section of the longitudinal element is rigidly connected to two spacers lying on one straight line, forming flat modules in the form of the letter “T”. Flat modules are pivotally connected to supports and adjacent modules. To ensure geometric immutability, the flat modules are connected by ties and are held in the design position by cable strands. Solution [7] is taken as a prototype.

The disadvantage of the solution [7] is the increased cost due to the presence of a large number of elements straining cable ropes.

The technical task of the invention is to reduce the cost of building construction through the use of inventory devices straining cable ropes, as well as reducing the cost of its transportation to the construction site.

The technical result of the invention is achieved by the use of a multi-section building structure, consisting of flexible belts made of strained cable ties connected to flat sections that are connected by links and pivotally connected to foundations or adjacent sections. Each flat section consists of a spacer and two rods located at an angle to each other, pivotally connected to each other and with the center of the spacer. Cable guy cables are tensioned by increasing the heights of the flat sections by moving one of the supports of each section.

The proposed technical solution is described by the following graphic materials:

In FIG. 1 shows a fragment of the proposed building structure in the process of creating prestresses in cable guy wires (side view).

In FIG. 2 shows a fragment of the proposed building structure, consisting of two parallel sections connected by links (axonometric diagram).

In FIG. 3 shows an example of the application of the proposed technical solution in the design of the rack (side view).

In FIG. 4 shows a section of the proposed building structure in the folded position, prepared for transportation.

The proposed technical solution consists of flexible belts made of strained cable ties 4 connected to flat sections 9, which are connected by ties 7, 8 and pivotally connected to foundations or adjacent sections 10 (Fig. 1, 2).

Each flat section 9 consists of a spacer 3 and two rods 1, located at an angle to each other, pivotally connected to each other and with the center of the spacer 3 in node 2. With the foundations or adjacent sections 10, the rods 1 are connected by hinged nodes 2b and 2c.

Links 7 made of hinge rods combine adjacent spacers 3, connecting with them in the hinge nodes 2A, forming a flat hard disk 11 (Fig. 2).

The cable guy wires 4 are tensioned by increasing the heights of the flat sections 9 by moving the pivotally movable temporary support 2g along the cantilever section 3a of the spacer 3 before aligning it with the hinge unit 2b (Fig. 1). The cantilever section 3A is provided with a guide, the design of which is known and is not the subject of the proposed technical solution.

The movement of the node 2g in the direction of the node 2B is carried out by a tensioning cable 5 using a tensioner 6 (for example, a shrink disk), the design of which is known and is not the subject of the proposed technical solution.

The spatial stability and geometric immutability of the proposed building structure is ensured by the installation of each subsequent (higher) section 9 on the lower structures (foundations or adjacent flat sections) previously fixed from displacements 10, as well as by setting ties 7, 8 and cable braces 4, namely (Fig. . 2):

- guy wires 4, strained during the installation of the building structure, are kept from turning the spacers 3 relative to the transverse axes Y passing through the fixed hinges 2;

- communications 8 together with hard disks 11 keep flat sections 9 from turning relative to the transverse axes X;

- hard drives 11 mounted on two pivotally fixed supports 2, prevent rotation relative to the longitudinal axes Z.

The proposed building construction is delivered to the construction site in the form of a set of identical (unified) flat sections 9 in the folded (packed) state (Fig. 4), ties 7, 8 and cable braces 4, as well as inventory tensioning devices (cable 5 and tensioner 6 )

Installation of the proposed building structure is as follows (Fig. 1, 2):

- mounted on fixed and secured against displacements supports 10 (foundations, or previously mounted sections), flat sections 9 are mounted. Flat sections 9 are mounted on articulated fixed 26 and movable 2g supports, after which they are temporarily fixed from movements by known methods (for example, in conductors, or supported by lifting mechanisms using traverses);

- connections 7 and 8 are established, as well as cable guy wires 4;

- tensioning cables 5 are installed with tensioning devices 6. Moving supports 2g are moved along cantilever sections with guides 3a, in the direction of nodes 2b. As a result, the heights of the mounted flat sections increase, and in the cable guy wires 4 there are prestresses;

- movable supports 2g upon reaching nodes 2c are fixed motionless by known methods (for example, by welding or bolting), after which inventory tension cables 5 with tensioning devices 6 are dismantled (for use in the installation of the next section). The remaining cantilever sections 3a are either cut off or used to mount lighting lamps, equipment, or other elements used in the operation of the proposed building structure.

The advantages of the proposed technical solution include the following:

- the manufacturability of the creation of prestressing, the possibility of using inventory tensioning devices;

- compact sections prepared for transportation to the construction site (Fig. 4);

- the ability to unify elements;

- the ability to dismantle and erect on a new site with minimal cost;

- the possibility of obtaining various structural forms and a wide scope.
