[0002] Reinforced truss floor decking is a new type of prefabricated floor slab, which combines the steel bars in the floor slab with the construction formwork. During the construction phase, it can withstand the deadweight of wet concrete and construction loads, becoming a building product that has both bearing capacity and formwork function. It has the advantages of reasonable force, energy saving and environmental protection, and is widely used in high-rise buildings, bridge structures, tunnel structures, underground parking lots, underground passages, ring beams, foundations, cast-in-place roofs of floors, shear walls and other fields.

[0003] However, the steel bars of the steel truss floor deck are distributed in multiple groups, which are connected to the bottom form as a whole, making it inconvenient to disassemble the two. The welding of the two will make it impossible to disassemble them for reuse, and multiple screw connections will require the screws to be removed one by one during the disassembly process. The disassembly process is time-consuming and labor-intensive, and the rapid disassembly of the steel truss floor deck cannot be achieved.
