The reinforced truss floor deck is a combination formwork in which the steel bars in the floor are processed into steel trusses with imported equipment in the factory, and the steel trusses and galvanized steel plates are welded into one in the factory. The formwork system combines the steel bars in the concrete slab with the construction formwork to form a load-bearing member that can bear the weight of the wet concrete and the construction load during the construction stage, and the member can be used as the lateral support of the steel beam during the construction stage. During the service phase, the steel trusses work together with the concrete to carry the service loads.
At the construction site, the steel truss floor deck can be laid directly on the steel beams, and then the concrete can be poured after simple reinforcement works. There is no need to set up wooden formwork and scaffolding to use this formwork. The galvanized profiled steel plate at the bottom is only used as a formwork and does not replace the stressed steel bars, so there is no need to consider the problems of fire protection spraying and anti-corrosion maintenance. Moreover, the steel bars are arranged evenly, and the upper and lower layers of steel bars The spacing and the thickness of the concrete protective layer can be fully guaranteed, which creates favorable conditions for improving the construction quality of the floor slab. After pouring concrete to form a floor slab, it has many advantages such as high overall rigidity, good seismic performance, good impact resistance, and good waterproof performance.
