[0002] Steel decking, also known as profiled steel sheet, steel floor decking, or steel floor slab, refers to pressed steel sheets that support concrete floors. Steel decking is made from galvanized steel sheets through roll forming and cold bending, resulting in V-shaped, U-shaped, trapezoidal, or similar corrugated cross-sections. It is primarily used as permanent formwork but can also be selected for other applications. The product is widely used in steel structure buildings such as power plants, power equipment companies, car showrooms, steel structure workshops, cement warehouses, steel structure offices, airport terminals, railway stations, stadiums, concert halls, theaters, large supermarkets, logistics centers, and Olympic venues.

[0027] Reference Figure 1-4 This utility model provides an embodiment of a detachable steel truss floor deck quick-connect locking device, comprising a floor deck body 1, with horizontal support bars 2 provided at the upper end of the floor deck body 1, connecting bars 3 connecting the horizontal support bars 2, a steel frame 4 installed above the horizontal support bars 2, web bars 5 provided inside the steel frame 4, threaded holes 6 opened inside the floor deck body 1, a groove 7 provided on one side of the outer wall of the floor deck body 1, and a connecting protrusion 8 installed on the other side of the outer wall of the floor deck body 1. A locking post 9 is installed on the surface. The bottom of the locking post 9 is provided with a pin hole 10. A fixing rod 11 is connected to the outer wall of the locking post 9. A threaded connecting pipe 12 is installed between the fixing rods 11. A fixing bolt 13 is installed at the bottom of the floor deck body 1. The outer layer of the floor deck body 1 is provided with fireproof coating A14. A galvanized steel plate A15 is connected to the bottom of the fireproof coating A14. A concrete base 16 is connected below the galvanized steel plate A15. A galvanized steel plate B17 is connected to one side of the concrete base 16. A fireproof coating B18 is provided at the bottom of the galvanized steel plate B17.

[0028] In this invention, the horizontal reinforcing bars 2 of the support are fixedly connected to the upper end of the floor slab body 1, the connecting reinforcing bars 3 are welded between the horizontal reinforcing bars 2 of the support, and the reinforcing bar frame 4 is fixedly connected to the upper end of the horizontal reinforcing bars 2 of the support by fixing bolts 13. There are several reinforcing bar frames 4, and the web reinforcing bars 5 are welded inside the reinforcing bar frame 4. This structural design makes the steel truss floor slab more stable overall and able to withstand larger loads. At the same time, the detachable design makes the installation and disassembly of the floor slab more convenient and quick, greatly improving construction efficiency.

[0029] Furthermore, the number of threaded holes 6 is several, and the internal threads of each threaded hole 6 are provided. The grooves 7 are formed on the outer wall of the floor deck body 1, and the connecting protrusions 8 are integrally connected to the outer wall of the floor deck body 1. The dimensions of the grooves 7 and the connecting protrusions 8 are matched, and the connecting protrusions 8 are inserted into the grooves 7. This design makes the connection between the floor deck bodies 1 tighter. Through the threaded holes 6 and corresponding threaded connectors, locking and fixing between the floor deck bodies 1 can be easily achieved, enhancing the stability and load-bearing capacity of the entire floor deck structure. At the same time, the cooperative design of the grooves 7 and the connecting protrusions 8 not only simplifies the installation process but also improves the accuracy and efficiency of the connection, ensuring seamless connection between the floor deck bodies 1 and further enhancing the overall performance of the entire floor deck.

[0030] Furthermore, the locking post 9 is inserted into the upper surface of the floor deck body 1, the pin hole 10 is opened at the bottom inside the locking post 9, and the fixing rod 11 is fixedly connected to the outer wall of the locking post 9. There are two fixing rods 11, and the threaded connecting tube 12 is threadedly connected between the fixing rods 11. This design enhances the connection stability between the locking post 9 and the floor deck body 1. The setting of the pin hole 10 allows the use of connecting parts such as pins to further fix the locking post 9 and prevent it from loosening or falling off. The combination of the two fixing rods 11 and the threaded connecting tube 12 not only provides additional support, but also allows the tightness of the threaded connecting tube 12 to be adjusted by rotating it, thereby achieving fine adjustment of the locking post 9 and ensuring its tight fit with the floor deck body 1.

[0031] Furthermore, the fire-retardant coatings A14 and B18 are fixedly connected to the outer layer of the floor decking body 1. The widths of fire-retardant coatings A14 and B18 are the same. The concrete base layer 16 is fixedly connected between galvanized steel plates A15 and B17. This design effectively improves the fire resistance of the floor decking body 1. The consistent width of fire-retardant coatings A14 and B18 ensures the uniformity of the fire-resistant layer, more effectively preventing the spread of fire. Simultaneously, the concrete base layer 16 enhances the overall load-bearing capacity and stability of the floor decking. The galvanized steel plates A15 and B17, as a sandwich structure, not only provide additional strength support but also exhibit good corrosion resistance, extending the service life of the floor decking. This multi-layered protective design comprehensively considers factors such as fire resistance, load-bearing capacity, and corrosion resistance, providing strong protection for building safety.

[0032] Furthermore, the galvanized steel plate A15 is fixedly connected between the fire-retardant coating A14 and the concrete base layer 16, and the galvanized steel plate B17 is fixedly connected between the concrete base layer 16 and the fire-retardant coating B18. The galvanized steel plates A15 and B17 have the same width. The galvanized steel plates possess excellent corrosion resistance, effectively resisting external environmental erosion and further extending the service life of the floor decking. This design not only improves the overall performance of the floor decking but also provides strong support for the safety and durability of the building.

[0033] Working principle and usage process: In use, first place the floor deck body 1 in a suitable position, then insert the connecting protrusion 8 into the groove 7 of another floor deck body 1, and lock the two floor deck bodies 1 by locking pin 9. The locking pin 9 is inserted into the upper surface of the floor deck body 1, and the pin hole 10 is opened at the bottom inside the locking pin 9. The locking pin 9 is fixed by the pin and other connecting parts. At the same time, the fixing rod 11 is fixedly connected to the outer wall of the locking pin 9, and the threaded connecting tube 12 is threadedly connected between the fixing rods 11, thereby realizing the quick connection and locking of the two floor deck bodies 1.

[0034] In addition, the fire-retardant coatings A14 and B18 in this utility model can effectively improve the fire resistance of the floor deck 1, while the galvanized steel plate A15 and B17 can enhance the corrosion resistance and durability of the floor deck 1, and the concrete base layer 16 can provide stable support.

[0035] This invention enables the rapid connection and locking of detachable steel truss floor decks, improving construction efficiency while ensuring the stability and safety of the floor decks.
