constructionhigh-strength

In multi-storey buildings and high-rise steel structure buildings, steel composite decking bearing plates and concrete are combined to form a whole. In such structure, the bearing plate bears construction load during construction, and acts with concrete during use to bear use load. 1: To meet the requirements of rapid construction of the main steel structure, it can provide a firm working platform in a short time, and can use multiple floors to lay floor decking plates and layer-by-layer pouring concrete slabs for flow construction. 2: In the use stage, the floor deck is used as the tensile reinforcement of the concrete floor, which also improves the stiffness of the floor and saves the amount of steel and concrete. 3: The embossing on the surface of the floor decking makes the maximum bonding force between the floorboard and the concrete, so that the two form a whole, with stiffeners, so that the floorboard system has a high-strength bearing capacity. 4: Under the cantilever condition, the floor deck is only used as a permanent formwork. The length of the overhang can be determined according to the section characteristics of the floor deck. In order to prevent the cracking of the cantilever plate, it is necessary to add negative reinforcement at the support according to the design of the structural engineer.
