Description

Technical Field

[0001] This utility model relates to the field of composite steel grating technology, specifically a high-strength composite steel grating that is easy to assemble and disassemble. Background Technology

[0002] Ordinary steel grating has an unsealed surface. If this grating is installed at a high position, people with a fear of heights will be terrified. In addition, the large gaps in steel grating allow large grains of sand and debris to easily fall through, posing a threat to pedestrians below. Therefore, composite steel grating was developed. In addition to overcoming the shortcomings of traditional steel grating, it also features high strength, lightweight structure, and ease of maintenance, making it widely used. Composite steel grating is a product composed of steel grating with a certain spanning capacity and a patterned plate with a sealed surface. It can be combined with any type of steel grating and patterned steel plates of different thicknesses.

[0003] In existing technologies, composite panels and steel gratings are usually fixed by welding to ensure the strength of the connection, but this increases the difficulty of disassembling and assembling the steel grating and composite panels. Therefore, there is a need for a high-strength composite steel grating that is easy to disassemble and assemble. Utility Model Content

[0004] The purpose of this utility model is to provide a high-strength composite steel grating that is easy to assemble and disassemble, thus solving the problems mentioned in the background art.

[0005] This application provides a high-strength composite steel grating that is easy to assemble and disassemble, including a steel grating, a composite plate installed on the top of the steel grating, a connecting plate fixedly connected to the outer wall of the steel grating, a fixing block fixedly connected to the outer wall of the composite plate, the fixing block engaging with the connecting plate, a threaded rod threaded through the outer wall of the fixing block, the threaded rod threadedly connected to the connecting plate, a limiting rod transversely threaded through the connecting plate, the limiting rod being located above the fixing block, and a nut fitted onto the outer thread of the limiting rod.

[0006] In use, first place the composite panel on top of the steel grating, so that the fixing block on the outer wall of the composite panel is fitted onto the connecting plate on the outer wall of the steel grating. Then, use screws to lock the fixing block and the connecting plate together. Next, insert the limiting rod horizontally into the upper part of the connecting plate to limit the fixing block, preventing the screw from loosening and falling off, which would cause the connecting plate to separate from the fixing block, thus improving the safety of use. The limiting rod can be fixed with nuts. This allows for quick assembly and disassembly of the steel grating and the composite panel, and increases the stability and firmness of the connection, making it less likely for the composite panel to shake.

[0007] Optionally, the steel grating has a slot, a steel rod is inserted into the slot, and locking blocks are threaded onto both ends of the steel rod.

[0008] By adopting the above technical solution, the steel rod can be inserted into multiple steel gratings under the action of the slot, so that the steel gratings can be spliced. After the splicing is completed, the two ends of the steel rod are locked by the locking block to prevent the steel gratings from falling off, and the combination installation of multiple steel gratings can be realized.

[0009] Optionally, a rubber layer is installed between the steel grating and the composite panel.

[0010] By adopting the above technical solution, the friction between the steel grating and the composite panel can be reduced.

[0011] Optionally, an anti-slip layer is fixedly connected to the top of the composite board, and the outer wall of the anti-slip layer is provided with anti-slip texture.

[0012] By adopting the above technical solutions, the anti-slip properties of composite boards can be improved.

[0013] Optionally, connecting rods are fixedly connected to both outer walls of the screw.

[0014] By adopting the above technical solution, the screw can be rotated manually more flexibly via the connecting rod.

[0015] Optionally, two limiting rods are provided, and the two limiting rods are arranged symmetrically on the left and right.

[0016] By adopting the above technical solution, the limiting rod can prevent the fixing block from separating from the connecting plate in the event of an accidental fall of the screw, thus improving the safety of use.

[0017] Optionally, the vertical cross-section of the connecting plate is an L-shaped structure.

[0018] By adopting the above technical solution, it is beneficial to install the fixing block.

[0019] Optionally, the fixing block is provided with a mounting groove that is compatible with the connecting plate.

[0020] By adopting the above technical solution, it is beneficial to improve the stability of the connection between the fixing block and the connecting plate and avoid shaking.

[0021] Optionally, a total of four connecting plates are provided, with each pair of connecting plates forming a group and symmetrically arranged on both outer walls of the steel grating.

[0022] By adopting the above technical solution, the strength of the connection between steel grating and composite panel is further improved.

[0023] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0024] The technical solution of this application first places the composite panel on top of the steel grating, so that the fixing block on the outer wall of the composite panel is fitted onto the connecting plate on the outer wall of the steel grating. Then, the fixing block and the connecting plate are locked and fixed by screws. After that, the limiting rod is inserted horizontally into the upper part of the connecting plate, which can limit the fixing block and improve the safety of use. The limiting rod can be fixed by nuts. Through the cooperation of the above structures, the steel grating and composite panel can be quickly assembled and disassembled, and the stability and firmness of the connection are increased, making it less likely to cause the composite panel to shake.

After the splicing is completed, the two ends of the steel rod 10 are locked by the locking blocks 11 to prevent the steel gratings 6 from falling off, and multiple steel gratings 6 can be combined and installed.

[0033] In the technical solution of this utility model, such as Figure 1 As shown, a rubber layer 7 is installed between the steel grating 6 and the composite panel 8; this reduces the friction between the steel grating 6 and the composite panel 8.

[0034] In the technical solution of this utility model, such as Figure 2 As shown, an anti-slip layer 9 is fixedly connected to the top of the composite board 8, and anti-slip texture 1 is provided on the outer wall of the anti-slip layer 9; this helps to improve the anti-slip properties of the composite board 8.

[0035] In the technical solution of this utility model, such as Figure 2 As shown, connecting rods 4 are fixedly connected to both outer walls of the screw 3; the screw 3 can be rotated manually more flexibly through the connecting rods 4.

[0036] In the technical solution of this utility model, such as Figure 3 As shown, there are two limit rods 14, which are symmetrically arranged on the left and right sides. In the event of an accidental fall of the screw 3, the limit rods 14 can prevent the fixing block 2 from separating from the connecting plate 5, thus improving the safety of use.

[0037] In the technical solution of this utility model, such as Figure 1 As shown, the vertical cross-section of the connecting plate 5 is an L-shaped structure, which facilitates the installation of the fixing block 2.
