Technical Field
[0001] This utility model relates to the field of building structural materials technology, and in particular to a high-strength load-bearing and compression-resistant steel grating. Background Technology
[0002] Steel grating, as a common building structural material, is widely used in industrial platforms, bridges, and walkways. Traditional steel grating is usually welded from flat steel and crossbars and has a certain load-bearing capacity. However, with the continuous improvement of industrial demands, traditional steel grating has gradually revealed its shortcomings in terms of load-bearing capacity, compressive strength, and durability, and cannot meet the needs of engineering construction.
[0003] A search revealed Chinese patent publication number CN222103381U, which discloses a high-strength steel grating comprising flat steel A and flat steel B. Multiple flat steel A bars are arranged in parallel, with multiple slots A extending through both sides of the top of each flat steel A bar at intervals. Multiple flat steel B bars are also arranged in parallel, with multiple slots B extending through both sides of the bottom of each flat steel B bar at intervals. The distance between two adjacent slots A is equal to the distance between two adjacent flat steel B bars, and the distance between two adjacent slots B is equal to the distance between two adjacent flat steel B bars. The distance between two adjacent flat steel bars A is equal. Flat steel bars A and B are inserted into slots A and B, and are welded together. In this utility model, the steel grating is made entirely of flat steel. Compared with the prior art which uses flat steel and twisted square steel, this utility model has higher strength, can withstand greater force, and is less prone to deformation during use. However, because the flat steel bars are fixed by welding, it is not convenient to quickly fix them during use, which increases the workload of the staff and cannot meet the needs of users. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0040] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a high-strength load-bearing and pressure-resistant steel grating, including an outer frame 1, an installation frame 3 on the inner side of the outer frame 1, a mesh steel grating 4 on the inner side of the installation frame 3, grooves 19 on both the left and right sides of the inner side of the installation frame 3, a locking block 5 slidably connected inside each of the two grooves 19, a lever 6 fixedly connected to the top of the opposite side of each of the two locking blocks 5, a sliding groove 7 on both the left and right sides of the top of the installation frame 3, the top of each of the two levers 6 passing through the corresponding sliding groove 7, a slot 8 on both the left and right sides of the mesh steel grating 4, the two locking blocks 5 respectively engaging with the corresponding slot 8, a reset component on the opposite side of each of the two locking blocks 5, the reset component being used to facilitate pushing the locking block 5 to engage with the slot 8, a protective mechanism 2 on the front and back sides of the inner bottom of the outer frame 1, the protective mechanism 2 being used to facilitate protection of the device, a limit block 13 fixedly connected to the adjacent end of each of the two sliding rods 10 passing through the corresponding locking block 5, and a rubber ball 12 fixedly connected to the top of the lever 6;
[0041] Specifically, when installing the mesh steel grating 4, first push the mesh steel grating 4 downwards. As the mesh steel grating 4 moves downwards, it will squeeze the locking block 5. The locking block 5 will be squeezed and move towards the groove 19, thereby applying pressure to the return spring 11. When the mesh steel grating 4 is inserted into place, the return spring 11 will push the locking block 5 to move. At this time, the moving locking block 5 will engage with the slot 8, thus being firmly fixed by the mesh steel grating 4, making the fixing work more convenient and quick. In addition, when it is necessary to disassemble the mesh steel grating 4, move the lever 6. The movement of the lever 6 will drive the locking block 5, causing it to disengage from the slot 8. The mesh steel grating 4 can then be easily disassembled, reducing the workload of the staff and meeting the needs of the users.
[0042] Reference Figure 1 , Figure 2 and Figure 3The protective mechanism 2 includes a mounting frame 201. Multiple mounting frames 201 are fixedly connected to the front, rear, left and right sides of the inner side of the outer frame 1. A fixing rod 202 is fixedly connected to the inner side of the mounting frame 201. A slider 203 is slidably connected to the left and right sides of the outer wall of the fixing rod 202. An energy-absorbing spring 207 is fixedly connected to one side of each slider 203. One end of the energy-absorbing spring 207 is fixedly connected to the mounting frame 201. A connecting rod 204 is rotatably connected to the top of the slider 203. Mounting grooves 205 are provided on the bottom left and right sides of the front and rear ends of the mounting frame 3. A support seat 206 is fixedly connected to the top left and right sides of the inner top of the mounting groove 205. The support seat 206 is rotatably connected to the connecting rod 204. The reset assembly includes a hollow tube 9. Two hollow tubes 9 are fixedly connected to the inside of the groove 19 at opposite ends. A sliding rod 10 is slidably connected to the inside of each of the two hollow tubes 9. A reset spring 11 is provided on the outside of each of the two hollow tubes 9. The adjacent ends of the two reset springs 11 are fixedly connected to the corresponding locking blocks 5.
[0043] Specifically, during the use of this device, when a pedestrian walks on the mesh steel grating 4, it will push the mesh steel grating 4 downward. The mesh steel grating 4 will then drive the support base 206 downward. During the downward movement of the support base 206, the connecting rod 204 connected to it can push the slider 203 to move. During the movement of the slider 203, it will apply pressure to the energy-absorbing spring 207. After being compressed, the energy-absorbing spring 207 will contract accordingly, which can absorb part of the impact force, thereby reducing the impact force directly acting on the mesh steel grating 4. This can greatly improve the service life of the mesh steel grating 4 and improve the practicality of the device.
[0044] Reference Figure 1 , Figure 2 and Figure 3 The mounting bracket 201 has a limiting groove 14 on its inner bottom. The bottom of the slider 203 is slidably connected to the limiting groove 14. The inner dimensions of the mounting frame 3 match the dimensions of the mesh steel grating 4. The inner dimensions of the groove 19 match the dimensions of the card block 5.
[0045] Specifically, the limiting groove 14 can limit the movement of the slider 203, so that the slider 203 can slide smoothly when pushed. The inner size of the mounting frame 3 matches the size of the mesh steel grating 4, so that the mesh steel grating 4 will not shake. The inner size of the groove 19 matches the size of the locking block 5, so that the locking block 5 can fix the mesh steel grating 4 firmly.
[0046] Reference Figure 1 , Figure 2 and Figure 3A rubber layer 15 is fixedly connected to the top of the mesh steel grating 4, and multiple reinforcing ribs 16 are fixedly connected at equal intervals to the bottom of the mesh steel grating 4. Mounting pieces 17 are fixedly connected to the bottom left and right ends and front and rear sides of the outer frame 1, and holes 18 are opened on the top of the multiple mounting pieces 17.
[0047] Specifically, the rubber layer 15 can prevent pedestrians from slipping, the reinforcing ribs 16 can improve the strength of the mesh steel grating 4, and the outer frame 1 can be easily and firmly fixed inside the holes 18 using bolts.
[0048] Working principle: When the mesh steel grating 4 needs to be installed, first push the mesh steel grating 4 downward. When the mesh steel grating 4 moves downward, it will squeeze the locking block 5. The locking block 5 will move to the side of the groove 19 and squeeze the return spring 11. When the mesh steel grating 4 is inserted into place, the return spring 11 will push the locking block 5 to move. The moving locking block 5 will engage with the slot 8, which can fix the mesh steel grating 4 firmly. The fixing work is more convenient and quick. When the mesh steel grating 4 needs to be removed, turn the lever 6. The lever 6 will drive the locking block 5 to move. The moving locking block 5 will disengage from the slot 8, which can remove the mesh steel grating 4.
[0049] Furthermore, during the use of this device, when a pedestrian walks on the mesh steel grating 4, it will push the mesh steel grating 4 downward. The mesh steel grating 4 will drive the support base 206 downward. When the support base 206 moves downward, it can push the slider 203 to move through the connecting rod 204. When the slider 203 moves, it will squeeze the energy-absorbing spring 207. When the energy-absorbing spring 207 is squeezed, it will contract and absorb part of the impact force, which can reduce the impact force on the mesh steel grating 4 and improve the service life of the mesh steel grating 4.
[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
