Fabricated steel structure self-supporting floor slab system edge cantilever end constraint structure

Abstract

The invention discloses an assembly type steel structure self-supporting floor system edge overhanging end constraint structure which comprises an I-shaped steel beam, wood blocks are placed on one side of a bottom plate of the steel beam at equal intervals, rectangular timber is erected between the top ends of the wood blocks, and a constraint structure body is installed at the bottom of the steel beam. The restraining structure comprises a right-angle limiting mechanism, a horizontal adjusting limiting mechanism and a vertical adjusting limiting mechanism, and the right-angle end of the right-angle limiting mechanism is clamped with one side of the bottom plate of the steel beam and the outer side of the wood block. According to the edge cantilever end constraint structure of the assembly type steel structure self-supporting floor slab system, wood blocks, long square timbers, long battens and constraint structures are arranged at equal intervals, horizontal and vertical free ends are fixed on the whole, cantilever square timbers of the self-supporting floor slab system are fixed to steel beams, a stable system is formed, and while safe and reliable connection is guaranteed, the self-supporting floor slab system is protected from being damaged. And the advantage of convenient construction is considered.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to an edge cantilever end restraint structure of a prefabricated steel structure self-supporting floor system. Background technique [0002] Steel structure building is a new building system that is different from traditional buildings. It replaces the traditional reinforced concrete or brick-concrete load-bearing system with fast, efficient and environmentally friendly steel component construction, and uses a self-supporting self-supporting pole-free supporting system. The support system pouring floor slab can solve the bottleneck problems of complicated construction methods, long construction period, high cost of erecting scaffolding and high construction risk factor for the steel structure floor slab system. The construction method needs to be improved between the steel structure building structure and the cast-in-place floor slab. How to choose a construction method with s...
