Description

Assembled shaped steel horizontal protection platform of encorbelmenting

Technical Field

The utility model belongs to the building field, concretely relates to assembled shaped steel level protection platform of encorbelmenting.

Background

With the rapid development of the building industry, high-rise and super high-rise buildings develop rapidly, and the requirements of temporary protection work on construction sites are higher and higher. Especially, some buildings are located in downtown areas, near-street areas and personnel-dense areas, and the potential safety hazards such as the throwing radius of the buildings and falling objects are inevitably considered. Meanwhile, in most construction processes, partial cross operation exists due to process requirements. Therefore, how to ensure that the bottom operating personnel and the external environment are not influenced by the upper construction in the building construction process reduces the potential safety hazard in the construction process, and further scientifically setting one or more temporary horizontal protections in the middle of the construction process is worthy of being explored by people.

The traditional horizontal protection platform that encorbelments of building mainly has following several:

1. the steel pipe is directly assembled and combined with the bamboo frame plates in a scattered mode, the steel pipe serves as an overhanging main beam, the floor pre-buried vertical steel pipe serves as an anchoring end, the overhanging steel pipe is connected with the pre-buried vertical steel pipe through double fasteners at the supporting end, the supporting end of the overhanging steel pipe is low, the outer side of the overhanging steel pipe is high, and pre-deformation is performed on the overhanging steel pipe in advance. The end part of the overhanging end adopts a steel wire rope as a drawknot, a common steel pipe is transversely placed on the overhanging steel pipe, is fixed by a fastener and is gradually erected from the building edge from inside to outside, and finally, a bamboo frame plate is laid on the steel pipe. The horizontal protection strength formed by adopting the combination of the forms is not high, and the impact resistance is not strong. The protection adopts steel pipe combination, and the integral rigidity is not enough, and has high requirement on the process erection quality, and the stability of the steel pipe combination can not meet the requirement of no deformation under the action of high-rise climate.

2. The steel pipe and bamboo frame plate combined cantilever beam is mainly operated by using I-shaped steel as a cantilever main beam on a selected floor, using a U-shaped ring as an anchoring end at the end part, and using a steel wire rope for pulling and connecting an I-shaped steel cantilever section. The common steel pipe is transversely placed on the I-shaped steel, is fixed by the fastener, is gradually erected outwards from the building edge, and finally the bamboo frame plate is laid on the steel pipe. Although the strength and the rigidity of the integral horizontal protection are effectively improved by adopting the method, the U-shaped ring needs to be pre-embedded in the floor in advance, the U-shaped ring needs to be cut off after the U-shaped ring is dismantled in the later period, and if the U-shaped ring is positioned in a structure with a waterproof requirement, water stopping treatment is also needed.

3. The beam is formed by combining I-shaped steel, steel pipes and bamboo frame plates, the main pulling and erecting method is similar to that of the type 2, and only the end part of the anchoring end of the overhanging I-shaped steel is fixedly connected on the structural beam by adopting a chemical anchor bolt. By adopting the method, the phenomenon that the U-shaped ring is directly embedded in the floor slab, but the anchoring fulcrum is arranged on the outer side beam, the chemical anchor bolt still has certain damage to the structure, and the side beam at the position of the balcony of the house belongs to the cantilever beam and can not be directly used as the anchoring fulcrum, so that the application range of the method is limited.

The three methods are all formed by utilizing materials such as steel pipes, bamboo frame plates, I-shaped steel and the like in a scattered splicing mode, so that all the materials need to be finished by operators at high altitudes without operation surfaces, great potential safety hazards exist for the operators, small parts easily fall off in the splicing process, potential safety hazards also exist for the operators below, and secondly, the process of the combination process is complex, the material waste is large, and the later-stage dismantling is also complex.
