1: The main steel structure to adapt to rapid construction requirements to provide a firm platform in a short time, and the use of multiple floor laying floor boards layer pressure plate, stratified water pouring concrete slab construction. 2: In the use phase as a concrete floor deck slab tensile reinforcement also improves the rigidity of the floor, saving the amount of steel and concrete. 3: The pressure plate embossed surface makes the concrete between the floor boards and the greatest binding force so that the two form a whole, with stiffeners, floor boards so the system has high strength bearing capacity. 4: In the boom conditions, the floor boards only as permanent formwork. According to the length of the cantilevered section properties of floor boards to be. To prevent cracking cantilevered plates required at the supports according to structural engineers design coupled with negative reinforcement. 5: The company has passed the floor boards fire resistance of the national fixed fire extinguishing systems and fire-resistant component quality inspection center for testing, as a combination of floor boards without fireproof coating, thus greatly reducing the project cost.
