Lichengda TDD assembly detachable steel bar truss floor deck is a combination template that processes the steel bars in the floor slab into steel trusses in the factory, and connects the steel bar truss into a combination of plastic fasteners, self-tapping nails and bamboo plywood. During the construction phase, the steel truss floor deck can withstand the construction load, lay directly on the beams, and the concrete can be poured by simple steel works. Due to the complete replacement of the formwork function, the formwork erection and dismantling works are reduced, and the construction efficiency of the floor slab is greatly improved.
