Prefabricated box plate steel structure multi-high-rise structure system and construction method

Abstract

The invention provides a multi-high-rise structure system and construction method of an assembled box plate steel structure, including a floor unit, a wall panel connection assembly and a floor connection assembly. There is a connection plate, the steel plate wall and the connection plate are fixed through the wall panel connection assembly, the wall panel connection assembly includes an L-shaped connection plate, a tapered rod, a screw, a base, a sliding frame and a tapered sleeve, and the two floor units that are connected to each other pass The floor connecting components are connected, and the bottom of the floor unit located on the upper floor is provided with a bottom plate, and the floor connecting components include sleeves, plugs, ratchet plates, ratchets and one-way bearings. The plug fits the inner wall of the sleeve, and the ratchet engages with the ratchet plate during the downward movement of the plug. The setting of the one-way bearing prevents the plug from moving upward, thereby realizing the self-locking effect of the floor unit, and when it is necessary to remove each other Move the ratchet plate when connecting the floor units, which can then be removed directly.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a prefabricated box plate steel structure multi-high-rise structural system and a construction method. Background technique [0002] The publication number is CN111287316B, which provides a prefabricated box plate steel structure multi-high-rise structure system, including the bottom unit and the standard floor unit. Composition, the inner side of the steel plate wall is welded with vertical stiffeners, the bottom side of the steel floor slab is welded with stiffeners, and the prefabricated concrete slab is attached to the outer side of the steel plate wall of the bottom unit. [0003] The steel plate wall, steel floor slab and precast concrete slab in the above-mentioned prior art all need to be connected by bolts, so the installation holes need to be aligned during the installation process, and the bolts need to be twisted for installation and disassembly, which...
