Description

The utility model relates to the field of construction and can be used to block 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 cost overrun 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. Decision [7] is taken as a PROTOTYPE.

The disadvantages of the solution [7] are the need to use a large number of bonds to ensure geometric structural immutability and the presence of compressed-curved elements working less efficiently compared to centrally loaded rods.

The technical task of the utility model is to simplify the design solution, reduce the cost of installation of the building structure and reduce the consumption of materials.

The technical result of the utility model is achieved by the use of a modular lattice building structure, consisting of geometrically unchanged modules combined by ties, held in a design position by tensioned cable ropes, pivotally connected to foundations or adjacent modules. Each module of a building structure consists of articulated rods forming two regular triangular pyramids having a common base.

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

In FIG. 1 shows a perspective diagram of a module of the proposed building structure.

In FIG. 2 shows a top view of the module of the proposed building structure and the location of the ties (option 1).

In FIG. 3 shows an axonometric diagram of the proposed building structure, consisting of two modules (the first variant of the location of the links).

In FIG. 4 shows an axonometric diagram of the proposed building structure, consisting of two modules (the second variant of the location of the links).

In FIG. Figure 5 shows a top view of the module of the proposed building structure and location of connections (option 2).

The proposed technical solution (Fig. 1, 2, 3) consists of geometrically unchanged modules 9, connected by ties 5 and held in the design position by strained cable ropes 4.

With the foundations, the modules 9 are connected by the hinged nodes 2b, and with the adjacent modules by the hinged nodes 2 and 2a (Fig. 1, 3), the design of which is known and is not the subject of the proposed technical solution.

To simplify the design solution and reduce the cost of installation of the building structure (due to the reduction in the number of connections), as well as to reduce the consumption of materials (due to the use of centrally loaded rods), each module 9 of the building structure is made of hinged rods 1, 1a and 3, forming two regular triangular pyramids 8 and 8a, having a common base 7 (Fig. 1).

Cable guy wires 4, for inclusion in the work of the building structure, are tensioned with special tensioning devices 6 (for example, turnbuckles or couplers), the design of which is known and is not the subject of the proposed technical solution.

To reduce the number of elements and simplify the modular building structure, it is proposed to install tie-braces 4a (Figs. 4, 5), replacing ties 5 and braces 4 (in Figs. 1-3).

The proposed modular building construction allows for the implementation of rectilinear and curved lattice racks, arched and vaulted structures. This is achieved by the use of cable brackets 4 (or tie-braces 4a) of the required length, together with unified (identical) modules 9.

Spatial stability and geometric immutability of the proposed building structure is ensured by the presence of geometrically unchanged modules 9 (hard disks), the installation of each subsequent (higher) module on the lower module previously fixed from movements, the setting of cable braces 4, as well as ties 5, or braces-ties 4a, namely:

- cable guy wires 4, strained during the installation of the building structure using special devices 6, keep the module 9 from turning relative to the transverse axes X and Y orthogonal to each other, passing through the fixed hinge supports 2, belonging to a plane parallel to the plane of the base 7 of module 9 (Fig. . 12);

- the torsion of the module 9 relative to the longitudinal axis Z passing through the fixed hinged supports 2 perpendicular to the plane of the base 7, is prevented by the connection 5 (Fig. 1, 2);

- tie-braces 4a (Fig. 4, 5) prevent the modules 9 from turning relative to the transverse axes X and Y passing through the fixed hinged supports 2, and also prevent the torsion of the modules 9 relative to the longitudinal axes Z.

The proposed modular lattice building structure is delivered to the construction site in the form of a set of identical (unified) modules 9, ties 5 or tie-braces 4a, as well as a variety of cable braces 4 (generally different lengths).

Installation of the proposed building structure is as follows:

- on a pivotally fixed support 2 belonging to a previously installed and fixedly mounted module 9, or on supports 2b which are the foundations of a building structure, module 9 is installed. Module 9 is temporarily fixed from movements by known methods;

- cable guy wires 4 and, if necessary, tie-guy wires 4a are installed. Tension 4 and 4a is made with special devices, for example, shrink discs;

- if necessary, links are established 5;

- the next module is installed in the same way.

The advantages of the proposed technical solutions include the following:

- simplification of the design solution and reduction of installation costs (due to a decrease in the number of connections);

- reduction in material consumption (due to the use of centrally loaded rods, instead of compressed-curved elements);

- the possibility of obtaining various structural forms;

- a wide scope of the proposed solution: racks, awnings and arched structures, operated both in temporary and in permanent structures;

- the ability to unify elements (modules 9);

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