Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a prefabricated building staircase. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] The existing prefabricated stair treads have a relatively smooth surface, making it easy to slip in rainy or snowy weather. Mud and dirt from shoes can also easily be brought indoors, which is very inconvenient. Utility Model Content

[0004] This utility model provides a prefabricated building staircase, which solves the problems of staircases being difficult to disassemble and assemble and inconvenient in rainy and snowy weather.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A prefabricated building staircase includes multiple vertically distributed kickboards and horizontally distributed treads. Each kickboard has multiple interlocking posts at both the top and bottom ends, and each tread has multiple interlocking slots at the front end of the upper surface and the rear end of the lower surface. Two kickboards adjacent to the same tread are spliced ​​to the front and rear ends of the tread by means of the multiple interlocking posts and multiple interlocking slots.

[0007] The top of the pedal is covered with multiple anti-slip baffles.

[0008] Preferably, both the kick plate and the pedal have round holes, and a fixing rod is inserted horizontally through the round holes.

[0009] Preferably, an H-shaped support plate is provided below the pedal, and the front and rear ends of the H-shaped support plate are respectively embedded in the pedal and the kick plate and are connected laterally through a fixing rod.

[0010] Preferably, a first bolt is threaded on one side of the insertion slot. When the insertion post and the insertion slot are inserted and mated, the insertion post and the insertion slot are fixedly connected by tightening the first bolt.

[0011] Preferably, an L-shaped fixing plate is fixedly provided at the bottom of the pedal, and two second bolts are threaded on the inner side of the L-shaped fixing plate. The L-shaped fixing plate is fixed to the kick plate and the pedal respectively by the two second bolts.

[0012] A fixing plate is fixedly provided on one end of the fixing rod, and a third bolt that can be connected to the wall is threaded on the fixing plate.

[0013] Preferably, one end of the fixing rod is threaded with a nut seat.

[0014] Preferably, the other end of the fixing rod is threaded with a nut seat.

[0015] Preferably, a rubber pad is fixedly provided on the outer side of the anti-slip baffle.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. Multiple plug-in posts and multiple plug-in slots are used to combine and splice the kickboard and treads. To facilitate splicing, the first bolt is used to fix the plug-in posts and plug-in slots to prevent the kickboard and treads from shaking. In rainy or snowy weather, in order to prevent slipping and falling down the stairs, an anti-slip baffle is fixedly installed on the surface of the treads. A rubber pad is fixedly installed on the outside of the anti-slip baffle. First, it can increase the friction between the sole of the shoe and the tread to prevent falling down the stairs. Second, it can effectively clean the mud and dirt on the sole of the shoe.

[0018] 2. In order to improve stability, this utility model adopts an L-shaped fixing plate to fix the bottom of the pedal, and fixes the connection between the kick plate and the pedal to prevent the connection between the kick plate and the pedal from breaking and avoiding unnecessary danger. In addition, an H-shaped support plate is provided at the bottom of the pedal to further improve the stability between the kick plate and the pedal. In order to fix it to the wall for more stability, a nut seat is provided at one end of the fixing rod to prevent the H-shaped support plate from causing the kick plate and the pedal to fall off.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model discloses a prefabricated building staircase.

[0028] This utility model provides, for example Figure 1-3 The prefabricated building staircase shown includes multiple vertically distributed kickboards 1 and horizontally distributed treads 2. Multiple insertion posts 3 are threaded to both the upper and lower ends of the kickboards. Multiple insertion slots 4 are machined at the front end of the upper surface and the rear end of the lower surface of the treads 2. Two adjacent kickboards 1 are connected to the front and rear ends of the same tread 2 through the engagement of the insertion posts 3 and the insertion slots 4. The number of insertion posts 3 and insertion slots 4 are equal. A first bolt 5 is threaded on one side of the insertion slot 4. When the insertion post 3 is inserted into the insertion slot 4, tightening the first bolt 5 fixes the insertion post 3 to the insertion slot 4, thus achieving a fixed connection between the kickboard and the tread. Multiple baffles 8 are fixedly installed on the top of the treads 2, and rubber pads 9 are fixedly installed on the outer side of the baffles 8. This design serves two purposes: first, it increases the friction between the sole of the shoe and the tread to prevent falls down the stairs; second, it effectively cleans mud and dirt from the soles of the shoes.

[0029] To improve the stability of the footboard and kick plate, round holes 6 are provided in both the kick plate 1 and the footboard 2, and a fixing rod 7 is inserted horizontally through each round hole 6, such as... Figure 1-4 As shown, an H-shaped support plate 12 is provided below the pedal 2. The front and rear ends of the H-shaped support plate 12 are respectively embedded in the pedal 2 and the kick plate 1 and are connected laterally through the fixing rod 7.

[0030] To secure the connection between the kickboard 1 and the pedal 2, such as Figure 1-2 As shown, an L-shaped fixing plate 10 is fixedly installed at the bottom of the tread 2. Two second bolts 11 are threaded on the inner side of the L-shaped fixing plate 10. The L-shaped fixing plate 10 is fixed to the baseboard 1 and the tread 2 respectively by the two second bolts 11. The L-shaped fixing plate 10 is placed at the connection between the baseboard 1 and the tread 2 and fixed using the second bolts 11. To make the staircase more stable within the wall, as... Figure 1-2As shown, a fixing plate 13 is fixedly installed on the wall of the fixing rod 7. A third bolt 14 is threaded on the fixing plate 13. The fixing rod 7 is inserted into the wall and the third bolt 14 on the fixing plate 13 is fixed to the wall.

[0031] The prefabricated building staircase design of this utility model uses multiple interlocking columns and multiple interlocking slots to combine and splice the kickboard and treads. To facilitate splicing, the first bolt is used to fix the interlocking columns and interlocking slots to prevent the kickboard and treads from shaking. In rainy or snowy weather, to prevent slipping and falling down the stairs, an anti-slip baffle is fixedly installed on the surface of the treads. A rubber pad is fixedly installed on the outside of the anti-slip baffle. First, it can increase the friction between the sole of the shoe and the tread to prevent falling down the stairs. Second, it can effectively clean the mud and dirt on the sole of the shoe.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
