Supporting floor concrete formed by pressing steel plate is called pressure plate, also known as floor bearing plate, steel bearing plate.
The combinedfloor deck is a product developed to meet the needs of reinforced concrete structures. The product is subjected to the construction load during the construction phase, and works in collaboration with the concrete in the service phase to bear the service load, thus able to give full play to the characteristics of the steel and the concrete materials. It enjoys the advantages of light weight, high strength, strong rigidity, simple construction, standardized in-factory production, and more.
The products are widely used in power plant, power equipment company, automobile exhibition hall, steel structure factory building, cement warehouse, steel structure office, airport terminal building, railway station, stadium, concert hall, grand theater, supermarket, logistics center, Olympic stadium and other steel structure buildings.
1. 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 be used to lay multiple floors of pressed steel plate, layered concrete slab water construction.
2. in the use stage, the floor bearing plate is used as the tensile reinforcement of the concrete floor, which also improves the stiffness of the floor and saves the amount of reinforcement and concrete.
3. pressure plate surface embossing between the floor bearing plate and concrete to produce the maximum binding force, so that the two into a whole, with stiffening rib, so that the floor bearing plate system has a high bearing capacity.
4. under cantilever condition, floor bearing plate is only used as permanent template. The length of the cantilever can be determined according to the section characteristics of the bearing plate. In order to prevent the crack of the cantilever plate, negative reinforcement should be provided at the support according to the design of the structural engineer.
We are a listed company in China, with abundant technical strength and advanced equipments since 1996, we have been undertaking kinds of design and manufacture of uniform and variable cross-section steel.
1. It can be used as a permanent template for cast-in-place concrete. In this way, the installation and removal of formwork during construction are eliminated, which saves time and labor.
2. When the floor bearing plate is installed, it can be used as a construction platform. At the same time, as there is no need to use temporary support, it does not affect the work of the next floor construction plane;
3. The floor bearing plate can be used as the bottom reinforcement of the floor, reducing the workload of installing the plate reinforcement;
4. According to the different section shapes of steel bearing plate on the floor, the amount of floor concrete can be reduced by up to 30%. The reduced floor weight can correspondingly reduce the size of beam, column and foundation, improving the overall performance of the structure;
5. Water, electricity and pipelines can be placed on the ribs of the steel support plate on the floor, so as to integrate the structural layer and pipelines, indirectly increasing the storey height or reducing the building height, thus bringing flexibility to the architectural design;
6. In the construction stage, the steel support plate on the floor can be used as the continuous lateral support of the steel beam, which improves the overall stable bearing capacity of the steel beam;
7. In the use stage, the overall stability of the steel beam and the local stability of the upper flange are improved;
8. Neat and beautiful appearance.
Decking steel structural can be used as a permanent template for cast-in-place concrete. In this way, the installation and removal of formwork during construction are eliminated, which saves time and labor.
Our company supply kinds of sandwich panel, City Multifunctional Kiosk，ALC/AAC panel and custom steel structural . Our products have high quality and competitive prices.
