Floor bearing plate

Floor bearing plate
The pressed steel plate supporting the floor concrete is called profiled steel plate, which is also called floor bearing plate and steel bearing plate.
Classification editing of floor bearing plate
Open floor bearing plate - necked floor bearing plate - closed floor bearing plate
Product application editor
The products are widely used in power plants, power equipment companies, automobile exhibition halls, steel structure plants, cement warehouses, steel structure offices, airport terminals, railway stations, stadiums, concert halls, Grand Theater, large supermarkets, logistics centers, Olympic stadiums and other steel structure buildings.
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 the flow construction of laying profiled steel plates on multiple floors and pouring concrete slabs in layers.
Main features editor
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 the flow construction of laying profiled steel plates on multiple floors and pouring concrete slabs in layers.
2: In the use stage, as the tensile reinforcement of the concrete floor, the floor bearing plate also improves the stiffness of the floor and saves the amount of reinforcement and concrete.
3: The embossing on the surface of the profiled plate makes the maximum binding force between the floor bearing plate and the concrete, and makes them form a whole. The floor bearing plate system has high bearing capacity with stiffeners.
4: Under cantilever condition, the floor bearing plate is only used as permanent formwork. The cantilever length can be determined according to the cross-section characteristics of the floor bearing plate. In order to prevent the cantilever slab from cracking, the bearing should be reinforced according to the design of the structural engineer.
Floor bearing plate is divided into three generations: open floor bearing plate, necked floor bearing plate and closed floor bearing plate.
The first generation of open floor bearing plate: it is only used as the permanent formwork of the floor, and can not work together with the concrete. The stress analysis is complex, so this kind of floor bearing plate is only used as the permanent formwork in the construction. After the concrete reaches 75% strength, the plate will not play any role. According to the statistics of the budget department, the overall cost of this kind of floor bearing plate in the project is 1.6 times of the cost of cast-in-place construction. It includes yxb76-305-915, yxb51-305-915, yxb75-200-600, yxb50-250-750 and yxb35-125-750;
Second generation shrinkage floor bearing plate: in this case, the designer improved the plate type, reducing the opening of the plate, that is, shrinkage plate, also known as swallow tail plate. This plate type can not only work with concrete, but also reduce the height of the concrete and weaken the area, greatly improving the fire prevention and anti-corrosion of the plate, and the floor stiffness is also higher than that of the open composite plate. Including yxb51-200-600;
Closed floor bearing plate: in consideration of the above problems, some designers add shear slots on the original floor bearing plate surface, and make them bear the force together through the wrapping effect of concrete, so as to increase the strength of the floor, which can not only make the floor bearing plate and concrete become a whole, but also save some tensile reinforcement. Through the improvement of designers, the second generation of closed and necked floor bearing plate gradually replaced the first generation of open floor bearing plate. It includes yxb65-185-555, yxb66-240-720, yxb65-170-510, yxb46-200-600 and yxb40-185-740.
