Description

Technical Field

[0001] This utility model relates to the field of steel truss floor decking technology, and in particular to a novel snap-fit ​​connector for steel truss floor decking. Background Technology

[0002] A steel truss is a truss constructed by resistance spot welding steel bars as the top chord, bottom chord, and web members. A steel truss floor deck is a composite load-bearing slab formed by resistance spot welding the steel truss to the base plate. Steel truss floor decks are a type of composite floor system used in steel structure buildings. During construction, steel truss floor decks can be used as formwork during concrete pouring, eliminating the need for additional formwork and saving significant time and labor. The steel truss, combined with concrete, forms a robust composite floor slab, providing excellent tensile, compressive, and shear strength, making it suitable for large-span structures. During construction, the floor deck provides workers with a safe working platform, facilitating simultaneous multi-level operations and accelerating construction progress.

[0003] Traditional floor decking mainly uses welding to connect steel trusses and bottom formwork. However, the connectors are mostly made of metal, which pollutes the air. Metal fasteners are also expensive, and once welded, they are difficult to remove. This makes it impossible to quickly disassemble and reassemble steel trusses and bottom formwork that are damaged before pouring. Therefore, a new type of snap-fit ​​connector for steel truss floor decking is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a novel snap-fit ​​connector for steel truss floor decking to solve the problems mentioned in the background art.

[0008] Preferably, a lower chord steel bar is slidably installed inside the disassembly and assembly mechanism, a web steel bar is fixedly installed on the lower chord steel bar, and an upper chord steel bar is fixedly installed on the web steel bar.

[0009] Preferably, the disassembly and assembly mechanism includes a snap-fit ​​hole on the first guide strip, a first support wall is fixedly installed on the upper surface of the snap-fit ​​connector base, the first support wall has an arc hole, a second support wall is fixedly installed on the upper surface of the snap-fit ​​connector base, an elastic snap-fit ​​wall is fixedly installed on the top of the second support wall, and a reserved hole is provided on the second support wall.

[0010] Preferably, the elastic card wall has a fixing surface, and the support block has a first guide surface.

[0011] Preferably, both the first support wall and the elastic card wall are provided with a second guide surface.

[0012] The beneficial effects of this utility model are:

[0013] In this utility model, by setting up structures such as the first support bar, the mounting tube, the mounting hole and the abutment, the snap-fit ​​connector base is placed on the bottom template body, the abutment abuts against the bottom template body, and the screw is screwed into the bottom template body.
