Description

A C-shaped buckle-connected fiber cement board-free formwork reinforced truss floor bearing board

Technical field

The utility model relates to the technical field of steel truss floor decking, and is specifically a formwork-free steel truss floor decking with C-shaped snap-connected fiber cement boards.

Background technique

The steel truss floor deck is a building product in which the stress-bearing steel bars in the floor slab are welded into steel trusses in the factory, and the steel trusses are fixedly connected to the bottom formwork to form an integrated bottom formwork and stress-bearing steel bars. During construction, the steel truss floor deck is fixed between two load-bearing beams, and concrete is poured directly. The bottom form bears the gravity of the concrete, and the steel truss provides unsupported stiffness for the bottom form. Compared with the traditional floor slab that uses bottom formwork to support concrete, the steel truss floor slab type speeds up the construction progress and enhances the support effect.

In the existing technology (publication number is CN208122063U, a disassembly-free steel truss floor deck is proposed), the structure includes a steel truss, a bottom formwork and a connecting fastener, and the bottom of the connecting fastener is fixed to the bottom formwork through a fixing piece On the top, the lower chord steel bars of the steel bar truss are clamped in the corresponding slots, which can realize the rapid assembly of the steel bar truss and the bottom formwork, significantly improving the assembly efficiency. In addition, after the concrete is poured, there is no need to disassemble the bottom form from the connecting fasteners, thereby eliminating the need for disassembly and further improving production efficiency. There is a groove on the bottom surface of the connecting fastener. When pouring concrete, the concrete can automatically flow into the groove, so that the concrete at the bottom of the connecting fastener and the concrete on the floor are connected as a whole, which can effectively prevent the occurrence of hollows and thus avoid the connecting buckle. The bottom concrete of the piece breaks off.

In the prior art, connection fasteners are used to achieve the purpose of eliminating disassembly. However, the connection strength of the existing connection fasteners is not high, the overall elasticity cannot meet the connection requirements, and disassembly and installation are troublesome.
