Description

(54) BYTE TOWER COOLED

one

The invention relates to the construction and can be used in the construction of tower structures, such as cooling towers.

A cooling tower is known, which includes a support post with a supporting ring-shaped element suspended from it and a pre-stressed shell in the form of a closed saddle-shaped membrane fixed in the foundation and ring-shaped element 1.

The disadvantage of this device is the complex constructive implementation, lack of stability and rigidity of the tower structure.

The closest to the technical essence of the invention is a cable-stayed tower cooling tower, comprising a central post with a stiffening ring attached to its top and an envelope wrapped in the foundations made in the form of a grid of mutually intersecting vertical and inclined pantoses and skin 2.

The drawbacks of the known cooling tower are the need to use intermediate stiffening rings to ensure the stability of the shell, considerable deformability of the joints, as well as the appearance of significant tensile loads transferred to the foundations.

The purpose of the invention is to increase the rigidity of the cooling tower, increase the reliability of the joints of the shell and reduce the load on the foundations.

This goal is achieved by the fact that in a tower tower cooling tower that includes a central rack with a stiffness ring suspended from its vertex and an anchor wrapped in the foundations, is made in the form of

10 grids of mutually intersecting vertical and inclined cables and common rail, vertical cables made in the form of prestressed trusses, which are connected by a lattice.

Truss can be spatially executed. ,

An embodiment of a lens-shaped truss is provided.

FIG. Figure 1 shows the facade of a cable-stayed cooling tower with vertical cables made in the form of double-sided lens-shaped trusses, a section; in fig. 2 shows a plan of a tower cooling tower with vertical flat trusses whose outer surfaces are connected by means of rigid or flexible connections; in fig. 3 is a plan of a cable-stayed cooling tower with vertical spatial trusses located along the perimeter adjacent to each other or with a gap; in fig. 4 - cable-stayed cooling tower with vertical trusses of a lenticular shape and skin attached to the inner and outer cus, section. The tower-tower cooling tower includes a central post 1 with a stiffening ring 3 suspended from its top by means of inclined cables 2, to which sheath 4 attached to the foundations 5 is attached. Vertical trusses can be two-dimensional flat lens-shaped 6 forms as well as spatial 7, for example, in the form of a trigrate. Flat trusses include outer 8 and inner 9 cas combined with a grille made of rigid struts 10 and flexible braces 11. Flexible braces 11 are made continuous along the entire height of the mold and have the ability to mix when creating pre-stresses in trusses. In order to ensure the spatial rigidity of the structure, internal cas 9 in the level of struts 10 of adjacent trusses 6 are joined by rigid annular elements 12. Spatial rigidity of external external planar trusses, if necessary, is provided by rigid annular elements 13, installed at a height of the cooling tower less often than internal, or flexible elements 14. Internal CA 9 flat trusses 6 and inclined cables 15 form a cable-stayed grid with triangular cells to which the sheathing 16 is fastened with ring elements 12. Sheathing 16 can It can be attached to the outer side of the truss truss 6 by means of rigid ring elements 13. The faces of the spatial trusses 7 are formed from flexible vertical lines 8 and 9, united by a grid made of rigid posts 10 and flexible braces 11. The hard stands 10 individual faces form closed triangular cross section. Spatial trusses 7 may be placed around the perimeter in a row or at some distance from each other. If necessary, to ensure spatial rigidity, they are rigid. elements 17. The vantow tower cooling tower structure is constructed as follows. Initially, the center post 1 and the foundations 5 are erected. Then, on the ground, by means of inclined cables 2, a ring 3 of rigidity is suspended, to which vertical trusses 6 and 7 and inclined cables 15 are attached. Ring 3 of rigidity gradually rises to the extreme upper position and a cable grid with triangular forms is formed by cells In order to provide spatial rigidity, the vertical trusses 6 and 7 are joined by inner 12 and outer 13 or 17 horizontal ring members. A prestressing of the cable-stayed net and the installation of the skin 16 with its fastening to the inner 12 or outer 13 horizontal rings are carried out. Such a solution of the tower tower cooling tower significantly increases the rigidity of the cooling tower, increases the reliability of the joints, shells, as well as the skin joints. In addition, in the presence of rigid struts in the lattice elements, it is possible to provide prestressing, which are partially quenched in the truss itself, which will make it possible to reduce the amount of prestressing transmitted to the foundations and to the central upright. Claim 1. Guards tower cooling tower, including a central rack with a stiffness ring suspended from its top and an envelope wrapped in the foundations, made in the form of a grid of mutually intersecting vertical and inclined cables and cladding, so as to increase the stiffness of the cooling tower, improving the reliability of the joints of the shell and reducing the load on the foundations; vertical cables are made in the form of prestressed trusses, which are connected by a grid. 2. Radar according to claim 1, characterized in that the trusses are spatial. 3. A radar under item 1, characterized in that the trusses are made of a lens shape.
