Problems solved by technology

[0003] The construction efficiency of this method is low, which is mainly reflected in:
[0004] 1) Caterpillar hoisting hooks, slow turning speed, hoisting blocks are in place at high altitude, and the fixing time is long;
[0005] 2) Frequent running and transition constructions cause serious wear and tear on crawler equipment;
[0006] 3) The reinforcement ring assembly occupies a large amount of space in the lower part, and its overall lifting process increases the amount of steel used in the original structure

Abstract

The invention provides a tower crane construction method of a large steel structural air cooling tower. The tower crane construction method comprises the following steps that (S1) two tower cranes are provided and located in an area of the air cooling tower; (S2), linear movement of the tower cranes is achieved through a rail type moving support, further hoisting of a triangular hoisting unit of a circular tapered section is conducted through linear movement and hoisting action of the tower cranes, the two tower cranes conduct symmetrical hoisting, and finally hoisting construction of the circular tapered section is completed; (S3), the positions of the tower cranes are fixed, further hoisting of a triangular hoisting unit of a cylinder section is conducted through action of the tower cranes, the two tower cranes conduct symmetrical hoisting, and after hoisting every layer of the cylinder section is finished, and hoisting of a triangular hoisting unit of an reinforcing ring corresponding to the layer is conducted through action of the tower cranes, so that the reinforcing ring is connected to the inner side of the cylinder section through quick positioning nodes, and the two tower cranes conduct symmetrical hoisting; and finally hoisting construction of the cylinder section is completed.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a tower crane construction method for a large steel structure air cooling tower. Background technique [0002] The existing large-scale air-cooling tower construction technology mainly adopts large-scale crawler cranes to hoist in blocks, and the reinforcement ring structure adopts the construction method of overall lifting after assembling on the ground. [0003] The construction efficiency of this method is low, which is mainly reflected in: [0004] 1) Caterpillar hoisting hooks, slow turning speed, hoisting blocks are in place at high altitude, and the fixing time is long; [0005] 2) Frequent running and transition constructions cause serious wear and tear on crawler equipment; [0006] 3) The assembly of the reinforcing ring occupies a large amount of space in the lower part, and its overall lifting process increases the amount of steel used in the original structure....
