Steel structure cooling tower with a cross plane truss system

Abstract

The invention discloses a steel structure cooling tower with a cross plane truss system. A tower body of the cooling tower is formed by connecting plane trusses in a combined mode, and the plane trusses include inclined trusses in two directions and horizontal trusses; the horizontal trusses and the inclined trusses in the two directions form a series of isosceles triangular grids, and out-of- plane supports of the plane trusses are arranged in the isosceles triangular grids; reinforcing ring trusses are arranged on the inner side of the tower body at certain height intervals; and widening platform trusses are arranged on the outer side of the lower part of the tower body. Compared with a traditional cooling tower with a steel bar and reinforced concrete structure, the cooling tower with the cross plane truss system and the steel structure has advantages that the force performance is good, the self-weight is low, construction is convenient, the construction period is short, and the construction cost is low; in addition, the cooling tower with the cross plane truss system and the steel structure makes full use of the in-of-plane rigidity of the plane trusses, thus the tower body ofthe cooling tower has good out-of-plane stability; by arranging supports in the out-of-plane direction of the plane trusses, the stability in out-of-plane of trusses can be improved, and the computinglength of out-of-planes of truss chord members is decreased; and through reasonable structure arrangement, the mechanical property of structure parts is fully exerted.

Description

technical field [0001] The invention relates to the field of structural design of large cooling towers, in particular to a steel structure cooling tower with a cross plane truss system. Background technique [0002] Cooling tower is a cooling facility widely used in electric power, steel, petroleum, chemical and other industrial fields. Its main function is to provide a place for heat exchange between cooling water and air carrying waste heat, so that waste heat can quickly disperse into the atmosphere, thereby Ensure the normal operation of the production system. [0003] Most of the existing large-scale cooling towers adopt a reinforced concrete rotating thin shell structure with a hyperbolic meridian, which has the characteristics of good stability and strong corrosion resistance. However, as the scale of industrial construction increases, the size of cooling towers also increases. Factors such as the weight of concrete structures and the resulting increase in costs make...
