↗The pressed steel plate supporting the floor concrete is called the pressed steel plate, also known as the floor bearing plate, steel bearing plate.
The characteristics of the floor bearing plate:
01
Adapt to the requirements of the rapid construction of the main steel structure, can provide a firm working platform in a short time, and can use multiple floors of laying molded steel plates, layering concrete slab flow construction.
02
In the use stage, the floor bearing plate is used as the tensile steel bar of the concrete floor, which also improves the stiffness of the floor and saves the amount of steel and concrete.
03
The surface embossing of the molded plate makes the maximum binding force between the floor plate and the concrete, so that the two form a whole, with stiffening ribs, so that the floor plate system has a high bearing capacity.
04
Under cantilever conditions, the floor bearing plate is only used as a permanent template. The length of the cantilever can be determined according to the cross-section characteristics of the floor plate. In order to prevent the cracking of the cantilever plate, it is necessary to install negative reinforcement at the support according to the design of the structural engineer.
