The Dingli TDV universal steel bar truss floor support plate is a composite formwork that processes the steel bars in the floor slab into steel bar trusses in the factory, and connects the steel bar trusses with galvanized steel plate bottom formwork to form a whole. The steel bar trusses bear the loads during the construction phase, and the bottom formwork supports the wet concrete. The steel bar trusses replace the stressed steel bars in the floor slab during use and work together with the concrete.
