Technical Field
The invention relates to the technical field of engineering construction, in particular to a portable platform for welding a bracket of a tower crane.
Technical Field
In the welding process of the corbel of the tower crane climbed in the current super high-rise layer, the problem that a platform for welding the corbel is difficult to erect is often faced. The tower crane mounted position is climbed in the superelevation layer generally to select in the elevator shaft, and there is not the plate structure in the elevator shaft, and bracket weldment work does not have horizontal working face, and the degree of difficulty is great.
At present, the site construction usually adopts the following two modes:
1. an overhanging fastener type steel pipe platform is erected on a tower crane standard section, and the steel pipe platform needs to adopt an overhanging form and has higher requirements on the length and the strength of a steel pipe. When the platform is assembled and disassembled, platform materials need to be hung in (out) and erected, the operation links of loose assembly (disassembly) are multiple, the construction time is long, the engineering progress is restricted, the bracket welding position is gradually increased along with gradual climbing of a tower crane, and the dangerousness of overhead operation is gradually increased.
2. The method comprises the following steps of installing an embedded part on a wall in advance, erecting an operation platform on the embedded part, and erecting the operation platform on a floor slab which is constructed around by an operator. Therefore, the method is only suitable for the construction of the inner frame floor slab following the core tube wall body, the floor slabs around the elevator shaft must be constructed, and the method has no wide applicability. And the embedded part can not be circulated, and the cost investment is large.
