Description

Technical Field

[0001] This utility model relates to a prefabricated staircase covering structure and belongs to the field of prefabricated building technology. Background Technology

[0002] Traditional prefabricated staircases often use metal materials such as stainless steel, aluminum alloy, or galvanized steel sheets. Although metal materials possess a certain strength, the anti-slip protrusions on their surfaces are prone to wear after prolonged foot traffic and friction. After a period of use, the stainless steel surface will wear down, weakening the anti-slip performance of the stair steps and significantly reducing their slip resistance. This, in turn, lowers the staircase's safety performance. Furthermore, because stainless steel steps are relatively expensive and often use bolts for connection and fixation, replacing the steps is costly, time-consuming, and labor-intensive, further reducing the practicality of prefabricated staircases.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a prefabricated staircase covering structure, which solves the problem that in the prior art, after a period of use, the stainless steel surface of the traditional prefabricated staircase will wear down, which will weaken the anti-slip performance of the anti-slip protrusions on the stair steps, significantly reduce the anti-slip performance of the stair steps, and thus reduce the safety performance of the staircase. Furthermore, because stainless steel steps are expensive and are mostly connected and fixed with bolts, the replacement cost of the steps is high and the replacement is time-consuming and laborious, which reduces the practicality of the prefabricated staircase.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: a prefabricated staircase covering structure, including two supporting side blocks, a stair slab between the two supporting side blocks, multiple supporting holes through the supporting side blocks, multiple supporting rods between the two supporting side blocks, the two ends of the supporting rods being inserted into the supporting holes, a supporting mechanism on the supporting side blocks for connecting and fixing the supporting side blocks and supporting rods, a limiting mechanism on the supporting side blocks for restricting the stair slab, multiple fixing slots on the supporting side blocks, multiple covering steps on the supporting side blocks, a supporting block fixedly connected to the covering steps that can be inserted into the fixing slot, an insertion slot on the supporting block, a sliding block on the supporting side blocks that can be inserted into the insertion slot, and a positioning mechanism on the supporting side blocks for driving the sliding block to be inserted into the insertion slot.

[0006] By adopting the above technical solution, during use, the stair slab is restrained between two support blocks by the limiting mechanism. The support rod is inserted into the support holes on the two support blocks, and then the support rod is rotated. Under the action of the support mechanism, the support blocks and the support rod are fixed. Then, the support block on the covered step is inserted into the fixing groove. Then, the positioning mechanism is rotated, and under the action of the positioning mechanism, the sliding block is driven to insert into the insertion groove on the support block. The sliding block inserted into the insertion groove has a fixing effect on the support block and also a fixing effect on the covered step. The covered step is installed on the stair slab and the support blocks to protect the stair slab. The installation is convenient, and the covered step can be disassembled individually, making the disassembly of the prefabricated stair covering structure more flexible and facilitating the replacement of the covered step after wear.

[0007] This utility model is further configured such that: the limiting mechanism includes a limiting step plate and a positioning step plate fixed on the supporting side block, and the stair tread is slidably connected between the positioning step plate and the limiting step plate. The supporting mechanism includes a fixing block fixedly connected to the supporting side block, the fixing block having a rotating groove, two positioning arc plates fixedly connected to the supporting rod that can be inserted into the rotating groove, the positioning arc plates having fixing holes, and a fixing bolt threaded onto the fixing block, penetrating into the rotating groove, the end of the fixing bolt penetrating into the rotating groove being able to be inserted into the fixing hole.

[0008] By adopting the above technical solution, during installation, the left and right sides of the stair tread are inserted between the left and right limiting step plates and the limiting step plates on the left and right sides. At the same time, the two ends of the support rod are respectively inserted into the support holes on the two support blocks. Then, the support rod is rotated, causing the support rod to drive the limiting arc plate to rotate, so that the limiting arc plate is inserted into the rotating groove during the rotation. Then, the fixing bolt is rotated, so that the end of the fixing bolt is inserted into the fixing hole. At this time, the fixing bolt fixes the limiting arc plate and the support rod, so that the support rod cannot rotate in the support hole. Multiple support rods connect and support the two support blocks, and the support rods can increase the connection strength between the two support blocks, thereby improving the load-bearing capacity of the staircase. Moreover, the installation is quick and efficient, thus improving the practicality of the prefabricated staircase covering structure.

[0009] This utility model is further configured as follows: the positioning mechanism includes multiple positioning grooves formed on the support side block, a sliding frame slidably connected in the positioning groove, a threaded hole penetrating the support side block, a threaded rod threadedly connected in the threaded hole, a sliding protrusion fixedly connected to the threaded rod and slidably connected to the inner wall of the sliding frame, the sliding protrusion being elliptical cylindrical in shape, the side of the sliding frame near the support block being fixedly connected to the sliding block, the end of the sliding block away from the sliding frame being able to be inserted into the insertion groove, one end of the threaded rod threadedly penetrating the outer side of the support side block and fixedly connected to a handle. Multiple return springs are fixedly connected between the side of the sliding frame away from the sliding block and the inner wall of the positioning groove, multiple sound-absorbing plates are fixedly connected to the inner wall of the covering step plate, and multiple anti-slip protrusions are fixedly connected to the covering step plate.

[0010] By adopting the above technical solution, when installing the covered step plate, rotating the handle causes the threaded rod to drive the sliding protrusion fixed thereon to rotate. During the rotation of the threaded rod, it can push the sliding frame away from the sliding block. During this process, the sliding frame compresses the return spring, causing it to deform, and simultaneously drives the sliding block to slide out of the fixing groove. At this time, the support block can be inserted into the fixing groove. When the lower surface of the support block abuts against the bottom wall of the fixing groove, the horizontal and vertical plates of the covered step plate abut against and fit against the support side block, the sound-absorbing plate, and the limiting step plate. Then, rotating the handle in the opposite direction... Under the release force of the return spring, the sliding frame and sliding block are pushed to reset, thereby causing the sliding block to insert into the insertion slot. The sliding block inserting into the insertion slot has a fixing effect on the support block and also has a fixing effect on the covering plate. This allows the covering plate to be installed on the two support side blocks to protect the stair treads. It is also easy to disassemble; the covering plate can be disassembled by turning the handle. The covering plate can be disassembled individually. When the covering plate is worn, it facilitates the maintenance of the staircase, reduces maintenance costs, and thus increases the practicality and economy of the prefabricated staircase covering structure.

[0011] The present invention is further configured such that: a reinforcing block is fixedly connected to the covered step plate, and a rubber arc strip is fixedly connected to the reinforcing block.

[0012] By adopting the above technical solution, after the cladding steps are assembled, the reinforcing block will abut against the vertical plate of its adjacent cladding steps, thereby increasing the fit between the vertical plate of the cladding steps and the supporting edge block. The rubber arc strip will also abut against the vertical plate of its adjacent cladding steps. The insertion groove can prevent dust and impurities from falling into the gaps between the cladding steps, making it easier to clean the stairs and thus increasing the practicality of the prefabricated stair cladding structure.

[0013] The beneficial effects of this utility model are as follows: When installing the covered step plate, rotating the handle causes the threaded rod to drive the sliding protrusion fixed thereon to rotate. During the rotation of the threaded rod, the sliding frame can be pushed away from the sliding block. During this process, the sliding frame compresses the return spring, causing it to deform. Simultaneously, it also drives the sliding block to slide out of the fixed groove. At this time, the support block can be inserted into the fixed groove. When the lower surface of the support block abuts against the bottom wall of the fixed groove, the horizontal and vertical plates of the covered step plate abut against and fit against the support side block, the sound-absorbing plate, and the limiting step plate. Then, rotating the handle in the opposite direction, under the action of the release force of the return spring, pushes... The sliding frame and sliding block are reset, which in turn causes the sliding block to insert into the insertion slot. The sliding block's insertion into the insertion slot fixes the support block and also fixes the covering plate. This allows the covering plate, installed on the two support side blocks, to protect the stair treads and is easy to disassemble. The covering plate can be disassembled by turning the handle, and it can be disassembled individually. The covering plate is made of plastic, which is low-cost, making the prefabricated stair covering structure more economical. When the covering plate wears down, it facilitates the maintenance of the staircase, reduces maintenance costs, and thus increases the practicality and economy of the prefabricated stair covering structure.

Detailed Implementation

[0022] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following details... Figures 1 to 6 As shown, this utility model is further illustrated.

[0023] like Figures 1 to 3 As shown, this utility model is a prefabricated staircase covering structure, including two supporting side blocks 1, a stair tread 3 between the two supporting side blocks 1, multiple supporting holes 9 through the supporting side blocks 1, multiple supporting rods 11 between the two supporting side blocks 1, the two ends of the supporting rods 11 being inserted into the supporting holes 9, a supporting mechanism on the supporting side blocks 1 for connecting and fixing the supporting side blocks 1 and the supporting rods 11, a limiting mechanism on the supporting side blocks 1 for restricting the stair tread 3, multiple fixing grooves 8 on the supporting side blocks 1, multiple covering steps 6 on the supporting side blocks 1, a supporting block 17 fixedly connected to the covering steps 6 that can be inserted into the fixing grooves 8, an insertion groove 26 on the supporting block 1, a sliding block 18 on the supporting side blocks 1 that can be inserted into the insertion groove 26, and a positioning mechanism on the supporting side blocks 1 for driving the sliding block 18 into the insertion groove 26.

[0024] In use, the stair tread 3 is restrained between two support blocks 1 by the limiting mechanism. The support rod 11 is inserted into the support hole 9 on the two support blocks 1. Then, the support rod 11 is rotated, and the support block 1 and the support rod 11 are fixed by the support mechanism. Then, the support block 17 on the covered step plate 6 is inserted into the fixing groove 8. Then, the positioning mechanism is rotated, and the sliding block 18 is driven to insert into the insertion groove 26 on the support block 17 by the positioning mechanism. The sliding block 18 inserted into the insertion groove 26 has a fixing effect on the support block 17 and also a fixing effect on the covered step plate 6. The covered step plate 6 is installed on the stair tread 3 and the support block 1 to protect the stair tread 3. The installation is convenient and the covered step plate 6 can be disassembled individually, making the disassembly of the prefabricated stair covering structure more flexible and convenient for replacement after the covered step plate 6 is worn.

[0025] like Figure 3As shown, the limiting mechanism includes a limiting step plate 4 and a limiting step plate 2 fixed on the supporting side block 1. The stair plate 3 is slidably connected between the limiting step plate 2 and the limiting step plate 4. The left and right sides of the stair plate 3 are respectively inserted between the limiting step plate 4 and the limiting step plate 2 located on the left and right sides.

[0026] like Figures 1 to 4 As shown, the support mechanism includes a fixed block 15 fixedly connected to the support side block 1. The fixed block 15 has a rotating groove 14. Two limiting arc plates 12 that can be inserted into the rotating groove 14 are fixedly connected to the support rod 11. The limiting arc plates 12 have fixing holes 13. The fixed block 15 is threaded with a fixing bolt 16 that passes through the rotating groove 14. The end of the fixing bolt 16 that passes through the rotating groove 14 can be inserted into the fixing hole 13.

[0027] During installation, the left and right sides of the stair tread 3 are inserted between the left and right limiting step plates 4 and the limiting step plates 2, and simultaneously the two ends of the support rod 11 are inserted into the support holes 9 on the two support blocks 1. Then, the support rod 11 is rotated, causing the limiting arc plate 12 to rotate, so that the limiting arc plate 12 is inserted into the rotating groove 14 during rotation. Then, the fixing bolt 16 is rotated, so that the end of the fixing bolt 16 is inserted into the fixing hole 13. At this time, the fixing bolt 16 fixes the limiting arc plate 12 and the support rod 11, so that the support rod 11 cannot rotate in the support hole 9. Multiple support rods 11 connect and support the two support blocks 1, and the support rods 11 can increase the connection strength between the two support blocks 1, thereby improving the load-bearing capacity of the staircase. The installation is quick and efficient, thus improving the practicality of the prefabricated staircase covering structure.

[0028] In this design, the limiting step plate 4 and the limiting step plate 2 work together to restrict and support the stair slab 3.

[0029] like Figures 1 to 5 As shown, the positioning mechanism includes multiple positioning grooves 20 formed on the support block 1. A sliding frame 19 is slidably connected in the positioning groove 20. A threaded hole 10 is formed through the support block 1. A threaded rod 21 is threadedly connected in the threaded hole 10. A sliding protrusion 22 that can slide and connect with the inner wall of the sliding frame 19 is fixedly connected to the threaded rod 21. The sliding protrusion 22 is in the shape of an elliptical cylinder. The side of the sliding frame 19 near the support block 17 is fixedly connected to the sliding block 18. The side of the sliding block 18 away from the sliding frame 19 passes through the fixed groove 8. The sliding protrusion 22 abuts against the inner wall of the side of the sliding frame 19 away from the sliding block 18. The end of the sliding block 18 away from the sliding frame 19 can be inserted into the insertion groove 26. One end of the threaded rod 21 is threaded through the outside of the support block 1 and is fixedly connected to a handle 25.

[0030] like Figure 5As shown, a plurality of return springs 27 are fixedly connected between the side of the sliding frame 19 away from the sliding block 18 and the inner wall of the positioning groove 20. The extension and retraction path of the return springs 27 is consistent with the sliding path of the sliding frame 19. A plurality of sound-absorbing plates 5 are fixedly connected to the inner wall of the covering step plate 6. The sound-absorbing plates 5 are slidably connected between the two limiting step plates 2. The sound-absorbing plates 5 are used to fill the gap between the two limiting step plates 2. A plurality of anti-slip protrusions 7 are fixedly connected on the covering step plate 6.

[0031] When installing the cover plate 6, rotate the handle 25 to make the threaded rod 21 drive the sliding protrusion 22 fixed thereon to rotate. During the rotation of the threaded rod 21, it can push the sliding frame 19 to move away from the sliding block 18. During this process, the sliding frame 19 squeezes the return spring 27 to deform it, and at the same time, it also drives the sliding block 18 to slide out of the fixing groove 8. At this time, the support block 17 can be inserted into the fixing groove 8. When the lower surface of the support block 17 abuts against the bottom wall of the fixing groove 8, the horizontal and vertical plates of the cover plate 6 abut against and fit against the support side block 1, the sound-absorbing plate 5 and the limiting plate 2. Then rotate the handle 25 in the opposite direction to reset. Under the release force of the spring 27, the sliding frame 19 and the sliding block 18 are pushed to reset, thereby causing the sliding block 18 to be inserted into the insertion slot 26. The sliding block 18 inserted into the insertion slot 26 has a fixing effect on the support block 17 and also has a fixing effect on the covering plate 6. This allows the covering plate 6 to be installed on the two support side blocks 1 to protect the stair tread 3 and is easy to disassemble. The covering plate 6 can be disassembled by turning the handle 25, and the covering plate 6 can be disassembled individually. When the covering plate 6 is worn, it facilitates the maintenance of the staircase, reduces maintenance costs, and increases the practicality and economy of the prefabricated staircase covering structure.

[0032] In this design, the cladding plate 6 is made of plastic, which is low-cost and makes the prefabricated staircase cladding structure more economical.

[0033] The sound-absorbing plate 5 is made of rubber. In this solution, the sound-absorbing plate 5 serves to reduce noise and fill the gap between the stair tread 3 and the covered step 6.

[0034] like Figure 6 As shown, a reinforcing block 23 is fixedly connected to the covered step plate 6, and a rubber arc strip 24 is fixedly connected to the reinforcing block 23. The covered step plate 6 is L-shaped, and the rubber arc strip 24 is made of silicone. Both the reinforcing block 23 and the rubber arc strip 24 are set on the horizontal plate of the covered step plate 6.

[0035] After the cladding plate 6 is assembled, the reinforcing block 23 will abut against the vertical plate of its adjacent cladding plate 6, thereby increasing the fit between the vertical plate of the cladding plate 6 and the supporting edge block 1. The rubber arc strip 24 will also abut against the vertical plate of its adjacent cladding plate 6. The insertion groove 26 can prevent dust and impurities from falling into the gap between the cladding plates 6, making it easier to clean the stairs and thus increasing the practicality of the prefabricated staircase cladding structure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
