[0002] Steel plate floor slabs refer to steel plates used in construction. The most common type is profiled steel plate composite floor slabs. This structure is usually composed of profiled steel plates and concrete. The profiled steel plates serve as both formwork and work together with the concrete to improve load-bearing capacity.

[0003] Currently, composite floor slabs are made by combining profiled steel sheets with a concrete layer. Profiled steel sheets, also known as slotted steel sheets, serve as templates and reinforcing bars. The composite floor slab is fixed to the steel beams by studs or welding, working together with the concrete. The overall structure features fast construction and high load-bearing capacity, and is widely used in industrial plants and high-rise buildings.

[0004] While steel plate flooring is currently available and allows for fast construction, its large size and weight make it difficult to handle during the construction process. The need for precise alignment during placement, combined with its weight, increases the workload and negatively impacts the overall construction efficiency.

[0005] Therefore, a quick-assembly and disassembly steel plate floor slab is proposed to address the above problems. Summary of the Invention

[0026] Specific implementation examples are given below.

[0027] Please refer to Figures 1-5. This utility model provides a quick-assembly and disassembly steel plate floor slab, including an upper steel plate 1 and a lower steel plate 2. A T-shaped insert 3 is fixedly connected to the bottom of the upper steel plate 1, and a T-shaped rail 4 is provided on the top of the lower steel plate 2. An upper locking block 5 is fixedly connected to one side of the upper steel plate 1, and a lower locking block 6 is fixedly connected to one side of the lower steel plate 2. An L-shaped upper locking groove plate 7 is fixedly connected to the side of the upper steel plate 1 away from the upper locking block 5, and an L-shaped lower locking groove plate 8 is fixedly connected to the side of the lower steel plate 2 away from the lower locking block 6. A connecting bolt 9 is threaded onto the inner surface of the L-shaped upper locking groove plate 7. One end of the connecting bolt 9 passes sequentially through the L-shaped upper locking groove plate 7, the upper locking block 5, and the lower locking block 6, extending into the interior of the lower locking block 6. During operation, the upper... Steel plate 1 and lower steel plate 2 form a complete steel plate floor slab. During installation, the required installation position is determined, and then lower steel plate 2 is simply placed in the corresponding position. After that, the T-shaped insert 3 at the bottom of upper steel plate 1 is inserted into the T-shaped insert 4 at the top of lower steel plate 2 to complete the installation. In general, multiple steel plate floor slabs need to be assembled to form a larger steel plate floor slab. Upper clip 5 is inserted into the groove of L-shaped upper clip 7, and lower clip 6 is inserted into the groove of L-shaped lower clip 8. The assembled upper steel plate 1 and lower steel plate 2 are fixed with connecting bolts 9. Therefore, assembly can be completed with less effort, thereby reducing the workload, avoiding the impact on construction, and improving construction efficiency.

[0028] Furthermore, as shown in Figures 2-4, the surface of the T-shaped insert 3 is slidably connected to the inner wall of the T-shaped rail 4, the top surface of the upper locking block 5 is engaged with the inner side of the L-shaped upper locking plate 7, and the bottom surface of the lower locking block 6 is engaged with the inner side of the L-shaped lower locking plate 8. During operation, the lengths of the T-shaped insert 3 and the T-shaped rail 4 are kept consistent and slightly shorter than the lengths of the upper steel plate 1 and the lower steel plate 2. The connection begins from one side of the upper steel plate 1 and the lower steel plate 2. The upper locking block 5 and the lower locking block 6 are inverted and face each other, engaging with the L-shaped upper locking plate 7 and the L-shaped lower locking plate 8 respectively, thus completing the installation.

[0029] Furthermore, as shown in Figures 1, 4, and 6, L-shaped slots 10 are provided on both sides of the top of the upper steel plate 1 and both sides of the bottom of the lower steel plate 2. A semi-open connecting plate 11 is inserted into the inner wall of the L-shaped slot 10, and an inverted triangular limiting block 12 is fixedly connected to the top of the semi-open connecting plate 11. A sealing clip 13 is inserted into the side of the semi-open connecting plate 11 near the upper clip 5 and the lower clip 6, and the bottom end of the sealing clip 13 extends through to the top of the upper steel plate 1 and the bottom of the lower steel plate 2. During operation, the L-shaped bayonet 10 is slightly shorter than the lengths of the upper steel plate 1 and the lower steel plate 2. A bayonet is formed on the side near the upper bayonet 5 and the lower bayonet 6, facilitating the insertion of the semi-open connecting block. The semi-open connecting block has a notch on the side away from the upper steel plate 1 and the lower steel plate 2, allowing the semi-open connecting block to be fully inserted into the L-shaped bayonet 10. The remaining part can still cover the parts of the upper steel plate 1 and the lower steel plate 2 that extend beyond the L-shaped bayonet 10. The entire assembly utilizes the semi-open connecting plate 11 in conjunction with the L-shaped bayonet 10. Then, the two upper steel plates 1 and the lower steel plate 2 are connected and fitted together by the inverted triangular limiting block 12. After installation, the semi-open connecting plate 11 is connected to the upper steel plate 1 and the lower steel plate 2 respectively by the sealing clamp 13, ensuring that the semi-open connecting plate 11 will not detach from the L-shaped bayonet 10, avoiding lateral deviation after installation, and ensuring the stability of the installation.

[0030] Furthermore, as shown in Figures 1, 4, and 5, support slots 14 are provided at the bottom of the upper steel plate 1 and the top of the lower steel plate 2. A slotted plate 15 is inserted into the inner wall of the support slot 14, and a support clamping plate 16 is inserted into the surface of the slotted plate 15. A connecting crossbar 17 is inserted into one side of the slotted plate 15. One end of the connecting crossbar 17 is inserted into one side of the inner wall of the upper steel plate 1 and the lower steel plate 2. A threaded cap 18 is fixedly connected to the end of the connecting crossbar 17 away from the upper steel plate 1 and the lower steel plate 2. The surface of the threaded cap 18 is threadedly connected to the surfaces of the upper steel plate 1 and the lower steel plate 2, respectively. During operation, the support slot 14 is used to insert the slotted plate 15. The insert plate 15 has a notch, while the support slot 14 does not completely penetrate the upper steel plate 1 and the lower steel plate 2. The top and bottom of the insert plate 15 also form a notch, so that after the insert plate 15 is fully inserted into the support slot 14, there is still a part of the space that extends to the position that is not penetrated by the support slot 14. The support clamping plate 16 can be inserted into the insert plate 15. Then, the connecting crossbar 17 is used to limit one side of the insert plate 15. The threaded cap 18 fixes the connecting crossbar 17 to the upper steel plate 1 and the lower steel plate 2, ensuring the stability of the connection between the upper steel plate 1 and the lower steel plate 2, and further improving the support effect of the assembled steel plate floor.

[0031] First, the upper steel plate 1 and the lower steel plate 2 form a complete steel plate floor slab. During installation, the required installation position is determined, and then the lower steel plate 2 is simply placed in the corresponding position. After that, the T-shaped insert 3 at the bottom of the upper steel plate 1 is inserted into the T-shaped insert 4 at the top of the lower steel plate 2 to complete the installation. Generally, multiple steel plate floor slabs need to be assembled to form a larger steel plate floor slab. The upper clip 5 is inserted into the groove of the L-shaped upper clip plate 7, and the lower clip 6 is inserted into the groove of the L-shaped lower clip plate 8. The upper steel plate 1 and the lower steel plate 2 are fixed by the connecting bolts 9. Therefore, the assembly can be completed with less effort, thereby reducing the workload, avoiding the impact on construction, and improving construction efficiency. In addition, the lengths of the T-shaped insert 3 and the T-shaped rail 4 are kept consistent and are slightly shorter than the lengths of the upper steel plate 1 and the lower steel plate 2. The connection is completed starting from one side of the upper steel plate 1 and the lower steel plate 2. The upper locking block 5 and the lower locking block 6 are inverted and face each other, respectively engaging with the L-shaped upper locking plate 7 and the L-shaped lower locking plate 8 to complete the installation. In addition, the length of the L-shaped bayonet 10 is slightly shorter than the length of the upper steel plate 1 and the lower steel plate 2. The bayonet is formed on the side near the upper bayonet 5 and the lower bayonet 6, which facilitates the insertion of the semi-open connecting block. There is a notch on the side of the semi-open connecting block away from the upper steel plate 1 and the lower steel plate 2, so that the semi-open connecting block can be completely inserted into the L-shaped bayonet 10. The remaining part can still cover the part of the upper steel plate 1 and the lower steel plate 2 that exceeds the L-shaped bayonet 10. The whole is made by using the semi-open connecting plate 11 in conjunction with the L-shaped bayonet 10. Then, the two upper steel plates 1 and the lower steel plate 2 are connected and fitted by the inverted triangular limiting block 12. After the installation is completed, the semi-open connecting plate 11 is connected to the upper steel plate 1 and the lower steel plate 2 respectively by the sealing clamp 13 to ensure that the semi-open connecting plate 11 will not detach from the L-shaped bayonet 10, avoid lateral deviation after installation, and ensure the stability of the installation. Finally, the support slot 14 is used to insert the slotted plate 15. The support slot 14 does not completely penetrate the upper steel plate 1 and the lower steel plate 2. The top and bottom of the slotted plate 15 also form a notch, so that after the slotted plate 15 is fully inserted into the support slot 14, there is still a part of the space that extends to the position that is not penetrated by the support slot 14. The support clamping plate 16 can be inserted into the slotted plate 15. Then, the connecting crossbar 17 is used to limit one side of the slotted plate 15. The threaded cap 18 fixes the connecting crossbar 17 to the upper steel plate 1 and the lower steel plate 2, ensuring the stability of the connection between the upper steel plate 1 and the lower steel plate 2, and further improving the support effect of the assembled steel plate floor.
