Description

Technical Field

[0001] This utility model relates to the field of floor decking technology, specifically a steel truss floor decking that is easy to snap and fix. Background Technology

[0002] Floor decking, also known as profiled steel sheet or steel decking, is a new type of building material used in building floor structures. Its main function is to serve as a permanent formwork during construction, bearing the load during the construction phase. At the same time, it can also serve as part of the floor structure during the service phase, sharing the service load with the concrete. Floor decking is widely used in large buildings such as industrial plants, warehouses, supermarkets, exhibition halls, stadiums, airport terminals, and railway station buildings, as well as in the floor structures of high-rise and super high-rise buildings.

[0003] There are various types of floor decking, among which steel truss floor decking is the first choice for large buildings, high-rise and super high-rise buildings due to its convenient construction, high load-bearing capacity and good seismic performance. Chinese Patent Publication No. CN 220908898U discloses a snap-fit ​​steel truss floor decking, which relates to the field of steel trusses. It includes a base plate, with multiple slots on both the left and right sides of the upper surface of the base plate. The slots of two corresponding slots are equipped with a locking element. The upper surface of the base plate is equipped with a positioning block inside the locking element. The upper surface of the base plate is equipped with multiple cavities, and each cavity is equipped with a locking device. The locking device includes a bidirectional threaded sleeve.

[0004] The aforementioned steel truss floor decking uses a snap-fit ​​structure primarily for connecting the steel truss and the base slab to facilitate subsequent disassembly. However, currently, the steel truss floor decking does not need to be disassembled after concrete pouring; instead, it becomes part of the floor structure, sharing the load during the service life with the concrete. Furthermore, there is no butt joint between adjacent base slabs of the aforementioned steel truss floor decking. When placing the steel truss floor decking, gaps will form between adjacent base slabs. During concrete pouring, this can cause concrete to leak from the gaps between the two base slabs, increasing the amount of concrete used and affecting the concrete's load-bearing capacity.

[0039] By adopting the above technical solution, when two adjacent plates 11 are joined together, the connecting plate 21 of one plate 11 is attached to the connecting plate 41 of the other plate 11. At this time, pressing the connecting plate 41 allows multiple arc-shaped blocks 42 to be inserted into multiple arc-shaped grooves 22 respectively, realizing the snap-fit ​​of the connecting plate 21 and the connecting plate 41, thereby achieving a fixed connection between the two plates 11. Moreover, there are no gaps between the two plates 11, which can prevent concrete leakage during concrete pouring.

[0040] In this embodiment, the top of the plate 11 near the slot 13 is uniformly and integrally provided with multiple clips 14, and the multiple clips 14 and the multiple steel trusses 3 are all the same length as the plate 11.

[0041] The sum of the thicknesses of the first connecting plate 21 and the second connecting plate 41 is the same as the thickness of the plate body 11, and the first connecting plate 21 is located below the second connecting plate 41.
