Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an assembled, disassembly-free steel bar truss floor deck. Background Art

[0002] A steel truss floor deck is a structural component made by processing steel bars into trusses and combining them with profiled steel sheets. It offers strong load-bearing capacity and convenient construction. During construction, it can be laid directly on steel beams, eliminating the need for formwork or scaffolding. After concrete is poured, it works in conjunction with the steel trusses to form a solid floor.

[0003] Prefabricated, non-disassembly steel truss floor decking is a new building material. It consists of steel trusses and a cement base plate. During construction, it can be assembled directly without removing the formwork. The steel trusses provide strong load-bearing capacity, while the cement base plate ensures flatness and durability. This floor decking is easy and quick to install, significantly shortening construction time, improving efficiency, and reducing project costs. It is widely used in prefabricated buildings.

[0004] During transportation, the existing assembled non-disassembly steel truss floor decking needs to stack two or more panels together. Although this is convenient for transportation, the floor decking cannot be limited to each other, which makes it easy for the middle floor decking to shift or even slide during transportation. To address the above problem, an assembled non-disassembly steel truss floor decking is proposed. Utility Model Content

[0014] As a further description of the above technical solution: support columns are fixedly connected to the left and right sides of the bottom of the web ribs, and the bottom of the support columns is fixedly connected to the positioning ribs.

[0015] By adopting the above technical solution, the welding between the web reinforcement and the positioning reinforcement can be made stronger by supporting them.

[0016] As a further description of the above technical solution: the top of the web rib is fixedly connected to the load-bearing column, and the bottom of the web rib is fixedly connected to the plate body.

[0017] By adopting the above technical solution, the web reinforcement is welded to the surface of the plate, which can make the load-bearing column connection more stable.

[0018] As a further description of the above technical solution: a second connecting plate is fixedly connected between the sleeves on the left and right sides, and a first connecting plate is fixedly connected between the sleeves on the front and rear sides.

[0019] By adopting the above technical solution, the first connecting plate fixes the sleeves on the front and rear sides, and the second connecting plate fixes the sleeves on the left and right sides.
