Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a multi-story assembled steel structure non-composite floor support system and a construction method thereof. Background Art

[0002] Building construction is the process of constructing a building according to architectural drawings. Multi-story prefabricated steel structures are prefabricated buildings whose structural systems are composed of steel components. Currently, the beam-column joints of prefabricated steel structures are mainly connected by bolt welding, but bolted joints are recommended for prefabricated steel structures. Prefabricated steel structures have the following advantages: no on-site cast-in-place joints, faster installation, and easier to ensure construction quality. The floor slabs in high-rise building steel structures usually use composite slabs or non-composite slabs formed by pouring concrete on corrugated steel plates. The corrugated steel plates are combined with cast-in-place concrete (after reaching the required strength). The corrugated steel plates serve as a permanent formwork for pouring concrete during the construction phase, and fully or partially act as the tensile reinforcement at the bottom of the slab during normal use. Floor slabs designed in this way are called composite slabs. They only serve as a permanent formwork for pouring concrete during the construction phase and completely withdraw from service during normal use. Floor slabs designed in this way are called non-composite slabs.

[0003] The existing multi-story prefabricated steel structure non-composite floor support system and its construction method are not convenient for rapid installation and connection of the support system, which reduces the installation efficiency of the corrugated steel plate and affects the formation of the concrete floor in the steel structure building.
