Description
Technical Field
The invention relates to an overhanging working platform convenient and fast to move, which can be widely applied to construction of all working procedures of an outer wall surface of an assembled steel structure building without a protective external scaffold.
Background
In the construction of the traditional concrete building, three main processes of formwork erecting, reinforcing steel bar binding, concrete pouring and the like are needed. In order to construct conveniently, a plurality of scaffolds need to be erected, support is provided for the building template, meanwhile, the scaffold is convenient for workers to operate, and a climbing and operating platform is provided. In the outside of building, have round confined outer scaffold, set up and demolish for the workman operates the template of outer wall in the outside, this scaffold also provides operation platform for the building outer wall fitment in later stage. The outer scaffold of concrete building generally takes to the top from the bottom along with the construction of building, along with outer decoration from the top down progressively under construction, the scaffold also progressively demolishs. The construction measures of the concrete external scaffold require certain construction cost.
In the assembly type steel structure building, steel structure component members are manufactured by factories and are assembled and constructed by tower cranes on site, and connecting nodes are mainly bolted and welded. In addition, the construction speed of the steel structure is high, 3-4 layers of steel beams can be simultaneously constructed on one section of steel column, the steel structure provides a firm framework, and workers can conveniently operate on the steel structure, so that a totally-enclosed external scaffold is not generally arranged in a high-rise project of the steel structure. The method is one of the main differences between the fabricated steel structure building and the traditional concrete building, and meanwhile, the construction measure cost is saved.
The construction of the outer wall of the assembled steel structure building mainly adopts a roof hanging basket mode, generally, after the main structure is completely capped, the hanging basket is fixed on the structural roof, the hanging basket is hung from the outer side of the building, and workers operate various procedures of the outer wall in the hanging basket. The construction process of the hanging basket cannot be used for simultaneous construction of multiple layers, and the efficiency of some cross operations is low.
If the building has not sealed the top, then the hanging flower basket does not have the place and takes root, and each item work of outer wall face has almost no operation platform, and the work of the outer wall face of construction this moment, workman's condition is dangerous relatively.
