Description

Assembled wallboard and floor board connection structure

Technical Field

The invention relates to the field of steel structure buildings, in particular to a connecting structure of an assembled wallboard and a floor board.

Background

Compared with the traditional concrete building, the steel plate or the section steel replaces reinforced concrete, so that the steel structure building has higher strength and better shock resistance. And because the components can be manufactured in factories and installed on site, the construction period is greatly reduced. Because the steel can be repeatedly used, the construction waste can be greatly reduced, and the steel is more environment-friendly, so the steel is widely adopted by all countries in the world and is applied to industrial buildings and civil buildings. At present, the application of steel structure buildings on high-rise and super high-rise buildings is mature day by day, and the steel structure buildings gradually become mainstream building processes, and are the development direction of buildings in the future. The steel structure building wallboard of the prior art mostly adopts the color steel sandwich board, although the construction is convenient, the heat preservation and heat insulation performance, the fire resistance, the sound insulation effect and the shock resistance are poor, and the board is easy to be damaged when being disassembled, and the repeated utilization rate is lower.

Autoclaved aerated concrete (ALC) is a light heat-insulating high-performance lightweight plate which is manufactured by taking high-quality silica sand or fly ash, quicklime, cement, a gas former, a bubble stabilizer and the like as raw materials through the working procedures of grinding, metering and proportioning, stirring and pouring, inserting and pulling a drill rod, gas forming and expanding, standing, cutting, autoclaved curing and the like. It can be used as the wall material of internal wall and external wall of building main body, roof board and floor board, and the thin plate (37 mm, 50mm in thickness) can be used as heat-insulating plate and fire-resisting plate, so that it is a new building material with excellent performance. But because the steel construction itself has better deformability, the elastic modulus of steel construction and ALC wallboard when receiving the temperature variation is mismatching simultaneously, leads to ALC wallboard and steel construction hookup location easy cracking.
