Abstract

The invention discloses a hyperbolic double-layer reticulated shell steel structure cooling tower, which comprises a bottom latticed column, a transfer truss and an upper tower tube, wherein the transfer truss is arranged at the upper part of the bottom latticed column; and the upper tower tube is arranged at the upper part of the transfer truss and is of a double-layer reticulated shell structure. The cooling tower adopts a hyperbolic appearance, so that the thermotechnical performance is good. Compared with a concrete thin shell tower, the cooling tower provided by the invention has the advantages that the dead weight is light; the foundation treatment is simple; and the construction is convenient and fast. Compared with a single-layer reticulated shell steel tower, the cooling tower provided by the invention has the advantages that a structure component mainly receives pulling and pressing stress; the strength of materials is fully used; the steel consumption is low; the structure rigidity is high under the condition of the same steel consumption; through the reasonable connection node design, the component field assembly can be realized; the construction is simple; the speed is high; and the anti-seismic performance and the wind-resistant performance are good.

Description

technical field [0001] The invention relates to a cooling tower, in particular to a hyperbolic double-layer reticulated shell steel structure cooling tower. Background technique [0002] At present, domestic large-scale cooling towers mostly adopt hyperbolic reinforced concrete thin-shell structures. This type of structure is widely used because of its high operational reliability, good corrosion resistance and long service life. At present, it is possible to design a large cooling tower with a diameter of more than 150m and a height of about 200m. With the development of steel structure technology, large-scale dry natural ventilation steel structure cooling towers have more and more technical advantages over concrete structures. Its light weight, simple construction, fast speed, excellent earthquake resistance and wind resistance, low overall cost, environmental protection, steel can be recycled after the service life of the steel tower is over, and many factors make the ...
