Self-stable suspension type unloading platform and construction process thereof

Abstract

The invention discloses a self-stable suspension type unloading platform and a construction process thereof. The unloading platform comprises main beams. Auxiliary beams are arranged between the mainbeams. Platform embossing steel plates are arranged among the main beams and the auxiliary beams. Vertical beams are arranged on the upper sides of the main beams. A rebar pull rod upper support is arranged among the vertical beams. A rebar pull rod lower support parallel to the rebar pull rod upper support is arranged at the bottom ends of the main beams. Rebar pull rods are arranged between therebar pull rod upper support and the rebar pull rod lower support. Upper floor system edge beams are arranged at the top ends of the vertical beams. A feed channel plate is arranged at the upper endsof lower floor system edge beams and the platform embossing steel plates. Compared with a traditional steel overhung unloading platform, embedded steel wire rope ring hanging, profile steel support ring anchoring, ending anchoring ring hole blocking and hanging ring rebar cutting treatment are not needed, and a passenger channel can be laid along a floor; construction installation and detachment operation is simple, safe and convenient, the installation and detaching construction period is shortened, embedded pieces and labor cost are greatly saved, the platform has remarkable economic and social benefits and meets the efficient, energy-saving and green construction requirements.

Description

technical field [0001] The invention relates to the construction field, in particular to a self-stabilizing suspended unloading platform and a construction process thereof. Background technique [0002] At present, the construction material turnover of the main structure of the building generally adopts the traditional steel cantilever unloading platform. However, the cable-stayed wire rope of the unloading platform belongs to flexible unloading, and it is easy to extend under the load, so that the anchor ring at the rear end of the steel main girder will produce overturning force, resulting in cracking of the cast-in-place slab and deformation of the eccentric force at the front end, which will easily cause structural quality defects. , and there are security risks.

Problems solved by technology

However, the cable-stayed wire rope of the unloading platform is flexible unloading, and it is easy to extend under the load, so that the anchor ring at the rear end of the steel girder will generate overturning force, resulting in cracking of the cast-in-place slab and deformation of the eccentric force at the front end, which will easily cause structural quality defects. , and there are security risks

[0003] The traditional steel cantilever unloading platform generally adopts pre-embedded post-anchor construction, and it is necessary to pre-embed steel wire layer suspension rings and steel beam anchor rings in the floor concrete. The embedded parts are difficult to remove and easily cause damage and cannot be reused. The installation and dismantling process is cumbersome, and the construction cost period is long. After the turnover of the traditional cantilever unloading platform is completed, there is a lot of finishing work such as the removal and treatment of the lifting ring, and the sealing of the reserved hole of the steel beam anchor ring. If the treatment is not good, prone to leakage
