Dongguan Zhenyu Steel Structure Engineering Co., Ltd.

The steel truss floor decking is a combined formwork in which the steel bars in the floor slab are processed into steel trusses using imported equipment in the factory, and the steel trusses and galvanized steel plates are welded together in the factory. This formwork system combines the steel bars in the concrete floor slab with the construction formwork to form a load-bearing component that can withstand the dead weight of wet concrete and construction loads during the construction stage, and this component can be used as a lateral support for steel beams during the construction stage. During the use phase, the steel trusses work together with the concrete to bear the use loads.
At the construction site, the steel truss floor deck can be laid directly on the steel beams, and then simple steel work can be performed to pour concrete. The use of this formwork does not require the erection of wooden formwork and scaffolding. The galvanized profiled steel plate at the bottom is only used as a formwork and does not replace the stress-bearing steel bars. Therefore, there is no need to consider the issues of fire-proof spraying and anti-corrosion maintenance. Moreover, the steel bars are evenly arranged, and the upper and lower layers of steel bars are The spacing and thickness of the concrete protective layer can be fully guaranteed, creating favorable conditions for improving the quality of floor slab construction. When concrete is poured to form a floor slab, it has many advantages such as high overall stiffness, good seismic resistance, good impact resistance, and good waterproof performance.
Mechanized production has been realized, which is beneficial to the uniform spacing of steel bars and consistent thickness of the concrete protective layer, which improves the construction quality of the floor slabs. The prefabricated steel truss floor decking can significantly reduce the amount of on-site steel tying work, speed up the construction progress, increase construction safety guarantee, and achieve civilized construction. The prefabricated formwork and connectors are easy to disassemble and assemble, can be reused many times, save steel, and comply with national energy conservation and environmental protection requirements. The products independently developed by the steel structure are equipped with automated production equipment, which greatly improves labor productivity and effectively reduces product costs. Product production enterprise standards, design manuals, node structure atlases, and construction manuals have been compiled. This product has been tested by the Zhejiang University Civil Engineering Testing Center and has been applied in many projects. Its performance can meet the requirements of the load-bearing capacity and deformation of cast-in-place reinforced concrete floor slabs.
