Multi-directional unloading system and construction method for assembling steel corridor by same

Abstract

The invention relates to a multi-directional unloading system and a construction method for assembling a steel corridor by the same. The multi-directional unloading system comprises two unloading units in left-right symmetry. Each unloading unit comprises an assembly bed jig for bearing the steel structure corridor, a support base for supporting the rear end of the assembly bed jig, a drag cable for providing an upward pulling force to the front end of the assembly bed jig, and an anchoring device for connecting the other end of the drag cable to a lateral building frame. The support bases arefixed to lower floor frame columns. The multi-directional unloading system and the construction method have the advantages that the load of the assembly bed jig of each unloading unit is borne by thecorresponding support base and the corresponding drag cable, the load in the splicing process of the steel corridor is borne by the lower floor frame columns and floor uprights on the lateral upper side and then is transferred to the foundation, and accordingly, excessive load on the top surface of a lower floor is avoided; the unloading effect is guaranteed through a simple structure, the problem that a large amount of materials and man hours are needed in the prior art is solved, and the multi-directional unloading system has a positive technical significance.

Description

technical field [0001] The invention relates to a multi-directional unloading system and a construction method for assembling a steel corridor by using the system, belonging to the technical field of building construction equipment. Background technique [0002] With the development of building construction technology, high-altitude corridors connecting two high-rise buildings are no longer rare, and steel structure corridors are usually used. Due to the high risk and high cost of aerial work, for high-altitude corridors, the scheme of "low-rise construction and overall improvement" is usually adopted. When carrying out "low-rise construction", it needs to be carried out on the ground between two high-rise buildings (that is, the basement roof, because the current high-rise buildings all have multi-storey basements) or on the top of the podium. [0003] Since the overall weight of the steel structure high-altitude corridor is very huge, it can even reach hundreds of tons; w...

Problems solved by technology

In the current existing technology, whether it is the initial design that adopts the reinforcement design scheme, or the temporary reinforcement of the overall bearing capacity during construction, there are problems of complex construction, long construction period, and high material consumption, and sometimes it will cause huge damage. redundant waste
