Hoisting system and hoisting construction method for large steel corridor trusses

Abstract

The invention discloses a hoisting system and a hoisting construction method for large steel corridor trusses. The hoisting system comprises lifting points, hanging points and jack lifting equipment. The jack lifting equipment is mounted between the lifting points and the hanging points, the lifting points comprise first lifting frames and second lifting frames, the first lifting frames are connected with first main structures, the second lifting frames are connected with second main structures, four embedded steel beams which have equal heights and are parallelly arranged are arranged in the two lifting frames of each lifting point, the lifting points are arranged at the ends of the embedded steel beams, two box-shaped brackets are respectively welded on two sides of each beam body of each lifting point, a jack is mounted on each box-shaped bracket, and each torsion-resistant steel beam is welded between the two corresponding box-shaped brackets on the inner sides of the beam bodies of the corresponding lifting points; the four corresponding hanging points which vertically correspond to the lifting points on a frame are arranged on each steel corridor truss, and steel strands penetrate the box-shaped brackets from top to bottom and are fixed by the aid of anchors after descending and penetrating the hanging points. Each large steel corridor truss can be synchronously lifted by the aid of the four corresponding hanging points during construction. The hoisting system and the hoisting construction method have the advantages that the hoisting system is reasonable in design and easy to operate, and problems of large occupied land areas, heavy dead weights and poor balance in existing large steel corridor truss hoisting procedures can be effectively solved by the aid of the hoisting system and the hoisting construction method.

Description

technical field [0001] The invention relates to the technical field of truss hoisting construction, in particular to a hoisting system and a hoisting construction method of a large-scale steel corridor truss. Background technique [0002] Corridor is a kind of complex high-rise building structure system. It generally refers to the connection between two or several high-rise buildings by overhead connectors to meet the requirements of building shape and use function. The connecting body is the corridor. Its span is several meters long, also has tens of meters long. There are one or several corridors arranged vertically along the building. On the one hand, the setting of the corridor is due to the requirements of architectural functions, and it can facilitate the connection between the two main structures. At the same time, the conjoined body has good lighting effects and a wide view, so it can be used as a sightseeing corridor or a leisure coffee shop; on the other hand, d...
