[0002] Floor decking, also known as profiled steel sheet, steel decking, or composite floor slab, is a type of building material made of galvanized steel sheet through roll forming. It is mainly used in steel structure buildings. According to the classification, floor decking includes three types: open, narrowed, and closed.

[0003] Currently, floor decking serves as a permanent formwork for concrete floor slabs, providing a stable working platform and supporting rapid steel structure construction. During use, concrete can be poured in layers, enabling continuous operation and shortening the construction period. In this process, it shares the load with the concrete, acting as the tensile reinforcement of the floor slab, thereby improving the overall rigidity and load-bearing capacity and reducing the amount of steel and concrete used.

[0004] In the current technology, when floor decking is used as a formwork, it needs to be laid. This laying process requires alignment and then fixing the floor decking. Either it is laid and poured at the same time, otherwise the floor decking is prone to lateral deviation, the overall construction progress is relatively slow, and the work efficiency needs to be improved.

[0005] Therefore, a prefabricated snap-fit ​​connection structure for floor decking is proposed to address the above problems. Utility Model Content

The two ends of the tension spring are respectively fixedly connected to one side of the inner wall of the circular groove and one end of the sliding retaining shaft.

[0009] Preferably, the number of convex cavities and T-shaped blocks is set to multiple, and the multiple convex cavities and T-shaped blocks are evenly arranged at equal intervals on both sides of the open floor deck and the auxiliary base. One side of the top of the wedge-shaped block is set as a semi-arc, and the bottom of the T-shaped block is set as a semi-circle.

[0010] Preferably, the surface of the open floor deck has multiple holes, and the surface of the open floor deck is fitted with a vertical load-bearing frame and a side-mounted elastic load-bearing frame through the holes.

[0011] Preferably, a rotating frame is fixedly connected to one side of the open floor deck, an L-shaped snap-fit ​​plate is rotatably connected to the surface of the rotating frame, and an installation clip is fixedly connected to the side of the open floor deck away from the rotating frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] Please see Figures 1-7This utility model provides a prefabricated snap-fit ​​connection structure for floor decking, including an open floor decking 1 and an auxiliary base 2. The auxiliary base 2 has mounting holes 3 on both sides and a convex cavity 4 inside. Circular grooves 5 are formed on both sides of the inner wall of the convex cavity 4. A sliding shaft 6 is slidably connected inside the circular grooves 5. A tension spring 7 is sleeved on the surface of the sliding shaft 6. A wedge-shaped stop 8 is fixedly connected to one end of the sliding shaft 6. T-shaped blocks 9 are fixedly connected to the bottom of both sides of the open floor decking 1. There are two circular grooves 5 and two wedge-shaped stops 8, symmetrically arranged on both sides of the convex cavity 4. During operation, the mounting holes 3 on the auxiliary base 2 allow it to be installed on the ground using connecting bolts. During installation, the auxiliary base 2 is moved to a suitable position, and the convex cavity 4 is used to... The open-face floor deck 1 and auxiliary base 2 are assembled. During assembly, the T-shaped locking block 9 at the bottom of the open-face floor deck 1 is pressed down along the wedge-shaped stop 8. When pressed down, the wedge-shaped stop 8 is pushed open by the T-shaped locking block 9, causing the sliding shaft 6 to slide into the circular groove 5. The tension spring 7 continues to be stretched, generating greater elastic force. When the T-shaped locking block 9 is fully engaged in the convex cavity 4, the wedge-shaped stop 8 loses its limit. The elastic force of the tension spring 7 will pull the sliding shaft 6 to slide outward, thereby pushing the wedge-shaped stop 8 to move and press against the T-shaped locking block 9, preventing the T-shaped locking block 9 from coming out of the convex cavity 4. This completes the installation. By setting the wedge-shaped stop 8 in conjunction with the T-shaped locking block 9, during installation, after the auxiliary base 2 is installed on the ground, the open-face floor deck 1 can be directly engaged in the auxiliary base 2. The operation is simple, and it can ensure the stability after installation, improve the construction progress, and thus ensure the installation efficiency.

[0019] Furthermore, such as Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, one end of the sliding retaining shaft 6 passes through the circular groove 5 and extends into the interior of the convex retaining cavity 4. The end of the sliding retaining shaft 6 located inside the convex retaining cavity 4 is fixedly connected to the surface of the wedge-shaped stop 8. Both ends of the tension spring 7 are fixedly connected to one side of the inner wall of the circular groove 5 and one end of the sliding retaining shaft 6, respectively. Multiple convex retaining cavities 4 and T-shaped blocks 9 are provided, and these multiple convex retaining cavities 4 and T-shaped blocks 9 are evenly and equidistantly arranged on both sides of the open floor deck 1 and the auxiliary base 2. One side of the top of the wedge-shaped stop 8 is semi-arc-shaped, and the bottom of the T-shaped block 9 is semi-circular. During operation, one end of the sliding shaft 6 passes through the circular groove 5, allowing the sliding shaft 6 to slide inside the circular groove 5. The other end of the sliding shaft 6 located outside the circular groove 5 is fixed with a wedge-shaped stop 8, allowing the wedge-shaped stop 8 to slide outside the circular groove 5. This achieves the cooperation between the wedge-shaped stop 8 and the T-shaped block 9. Multiple convex cavities 4 and T-shaped blocks 9 are provided on both sides of the open floor deck 1, which can further improve the stability after assembly. In addition, a semi-circular opening is provided on one side of the top of the wedge-shaped stop 8, and the T-shaped block 9 is set as a semi-circle. During installation, the semi-circular bottom of the T-shaped block 9 fits against the semi-circular top of the wedge-shaped stop 8, making it convenient for the T-shaped block 9 to push the wedge-shaped stop 8 open after being pressed down. When the T-shaped block 9 slides down, it will abut against the flat opening at the bottom of the wedge-shaped block, preventing the T-shaped block 9 from sliding out of the wedge-shaped block.

[0020] Furthermore, such as Figure 1 As shown, the surface of the open-type floor deck 1 has multiple holes 10. Vertical load-bearing frames 11 and side-mounted elastic load-bearing frames 12 are attached to the surface of the open-type floor deck 1 through these holes 10. During operation, the holes 10 in the open-type floor deck 1 are used to install the vertical load-bearing frames 11 and side-mounted elastic load-bearing frames 12. The vertical load-bearing frames 11 are installed on the top of the open-type floor deck 1, and the side-mounted elastic load-bearing frames 12 have elasticity on both sides and can be engaged with the horizontal holes 10 in the open-type floor deck 1. The vertical load-bearing frames 11 and side-mounted elastic load-bearing frames 12 increase the load-bearing capacity of the open-type floor deck 1.

[0021] Furthermore, such as Figure 1 , Figure 2 and Figure 4As shown, a rotating frame 13 is fixedly connected to one side of the open-ended floor deck 1. An L-shaped snap-fit ​​plate 14 is rotatably connected to the surface of the rotating frame 13. A mounting block 15 is fixedly connected to the side of the open-ended floor deck 1 away from the rotating frame 13. A connection notch 16 is provided on the inner side of the L-shaped snap-fit ​​plate 14. A semi-circular protrusion 17 adapted to the connection notch 16 is fixedly connected to one side of the mounting block 15. During operation, the L-shaped snap-fit ​​plate 14 can rotate on the rotating frame 13, and then snap onto the mounting block 15. At the same time, the connection notch 16 on the surface of the L-shaped snap-fit ​​plate 14 cooperates with the semi-circular protrusion 17 on the surface of the mounting block 15 to complete the connection between the L-shaped snap-fit ​​plate 14 and the mounting block 15. By setting up the rotating frame 13 and the L-shaped snap-fit ​​plate 14 in cooperation with the mounting block 15, two open-ended floor decks 1 can be assembled and then installed one by one, ensuring the stability after installation and further improving the adaptability of use.

[0022] First, the auxiliary base 2 has mounting holes 3, which can be used with connecting bolts to install the auxiliary base 2 onto the ground. During installation, the auxiliary base 2 is moved to a suitable position, and the convex cavity 4 is used to assemble the open floor deck 1 and the auxiliary base 2. During assembly, the T-shaped locking block 9 at the bottom of the open floor deck 1 is pressed down along the wedge-shaped stop 8. When pressed down, the wedge-shaped stop 8 is pushed open by the T-shaped locking block 9, causing the sliding locking shaft 6 to slide into the circular groove 5. The tension spring 7 continues to be stretched, generating greater elastic force. When the T-shaped locking block 9 is fully engaged with the convex cavity 4, the auxiliary base 2 is fully engaged with the convex cavity 4. After cavity 4 is closed, wedge-shaped stop 8 loses its limit, and the elastic force of tension spring 7 will pull sliding pin 6 to slide outward, thereby pushing wedge-shaped stop 8 to move and abut against T-shaped pin 9, so that T-shaped pin 9 will not come out of convex cavity 4, thus completing the installation. By setting wedge-shaped stop 8 in conjunction with T-shaped pin 9, during installation, only the auxiliary base 2 needs to be installed on the ground, and the open floor deck 1 can be directly inserted into the auxiliary base 2. The operation is simple, and the stability after installation is guaranteed, which improves the construction progress and thus ensures the efficiency of installation. Then, one end of the sliding pin 6 passes through the circular groove 5, allowing the sliding pin 6 to slide inside the circular groove 5. The wedge-shaped stop 8 is fixed at the other end of the sliding pin 6 located outside the circular groove 5, allowing the wedge-shaped stop 8 to slide outside the circular groove 5, thereby achieving the cooperation between the wedge-shaped stop 8 and the T-shaped stop 9. At the same time, multiple convex cavities 4 and T-shaped stops 9 are set on both sides of the open floor deck 1, which can further improve the stability after assembly. In addition, a semi-circular opening is made on one side of the top of the wedge-shaped stop 8, and the T-shaped stop 9 is set as a semi-circle. During installation, the semi-circle at the bottom of the T-shaped stop 9 fits against the semi-circular contact at the top of the wedge-shaped stop 8, making it convenient for the T-shaped stop 9 to push the wedge-shaped stop 8 open after being pressed down. When the T-shaped stop 9 slides down, the T-shaped stop 9 will abut against the flat opening at the bottom of the wedge-shaped stop 9, so that the T-shaped stop 9 will not slide out from the wedge-shaped stop 9. Next, the holes 10 made in the open floor deck 1 are used to install the vertical load-bearing frame 11 and the side-mounted elastic load-bearing frame 12. The vertical load-bearing frame 11 is installed on the top of the open floor deck 1, and the side-mounted elastic load-bearing frame 12 has elasticity on both sides and can be locked into the horizontal holes 10 of the open floor deck 1. The vertical load-bearing frame 11 and the side-mounted elastic load-bearing frame 12 increase the load-bearing capacity of the open floor deck 1. Finally, the L-shaped snap-fit ​​plate 14 can rotate on the rotating frame 13, and then the L-shaped snap-fit ​​plate 14 is locked onto the mounting block 15. At the same time, the connecting notch 16 on the surface of the L-shaped snap-fit ​​plate 14 cooperates with the semi-circular protrusion 17 on the surface of the mounting block 15 to complete the connection between the L-shaped snap-fit ​​plate 14 and the mounting block 15. By setting up the rotating frame 13 and the L-shaped snap-fit ​​plate 14 in cooperation with the mounting block 15, the two open floor decks 1 can be assembled and then installed one by one, ensuring the stability after installation and further improving the adaptability of use.
