Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building, in particular to a building stair. BACKGROUND

[0002] The concrete stairs used in existing building construction are formed by pouring on site or prefabricating in the factory, using inclined stair slabs and step platforms that are integrally poured and formed as a whole. After long-term use, individual steps of the step platform are prone to wear, causing concave pits on the tread surface. In poor visibility conditions, a person may fall if they step on a pit, and damaged steps cannot be replaced individually, which has certain defects.

[0003] The existing patent (publication number: CN213539526U) discloses a building stair, which includes an inclined base, a plurality of steps are arranged on the base, a plurality of insertion slots are arranged on the base along the length direction, the insertion slots are arranged along the width direction of the base and perpendicular to the base, and an insertion block is arranged on each step and inserted into the insertion slot. The base and the steps are detachably connected, so that the tread surface of the steps can be replaced in time after being damaged, avoiding injury caused by accidentally stepping on the damaged part of the steps.

[0004] In the above-mentioned comparative file, although the connection method of the steps and the base allows the tread surface to be replaced, the disassembly and replacement steps may be relatively complex in actual operation, and in addition, the insertion structure of the steps may loosen after long-term use, which may affect the overall stability and safety of the stairs. Utility model content

[0005] In view of the deficiencies of the prior art, the present application provides a building stair with the advantages of quick replacement and high stability, which solves the problems in the background art.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a building stair, comprising a base, a group of equidistantly arranged connecting slots are arranged on the inclined surface of the base, two positioning slots are fixedly arranged on the inner wall of each connecting slot, a through hole is arranged on the inner wall of each positioning slot, a connecting block is arranged in each connecting slot, a step is fixedly connected to the inclined surface of each connecting block, a pair of symmetrical telescopic rods are fixedly installed on the inner wall of each connecting block, a compression spring is fixedly connected to the inner wall of each connecting block, and a positioning plate is fixedly connected to the ends of the two telescopic rods and the two compression springs away from each other.

[0007] By the above scheme, through the combination of telescopic rod and compression spring, it is ensured that the connecting block can remain stable when subjected to external force, preventing the ladder block from loosening during use, and the fixing effect between the connecting block and the base is further enhanced through the setting of the positioning plate, thereby improving the stability and safety of the whole staircase, and since the compression spring exists, when the ladder block is subjected to pressure, the spring can absorb part of the impact force, reducing the direct impact on the connecting block, prolonging the service life of the staircase, so that a stable connection is formed between each connecting block and the base, and the ladder block can be quickly replaced when damaged.

[0008] Further, the upper surface of each ladder block is provided with a group of anti-skid grooves arranged at equal distances, and the maximum depth of each anti-skid groove is five millimeters.

[0009] By the above scheme, by setting the anti-skid grooves, the use safety of the ladder block in wet or slippery environment is significantly improved, and the risk of slipping when the user goes up or down the stairs is reduced.

[0010] Further, the side face of each group of positioning plates away from each other is fixedly connected with a threaded rod.

[0011] By the above scheme, by setting the threaded rod, the threaded structure of the threaded rod can ensure that the positioning plate remains stable after adjustment and does not shift position due to vibration or external force, thereby ensuring the stability and safety of the overall structure of the staircase.

[0012] Further, the upper surface of each ladder block is fixedly connected with a mounting seat, and a group of annularly arranged fixing holes are formed in the upper surface of each mounting seat.

[0013] By the above scheme, by setting the mounting seat and the fixing hole, not only is an additional support point provided for the ladder block, enhancing its structural strength, but also other auxiliary facilities such as handrails or lighting equipment can be conveniently installed through the fixing hole, further improving the practicality and safety of the staircase.

[0014] Further, the outer surface of each threaded rod is sleeved with a rubber pad, and each group of rubber pads is located on the left and right sides of the base.

[0015] By the above scheme, by setting the rubber pad, the vibration generated during the use of the staircase can be effectively absorbed, reducing noise, and at the same time, the threaded rod is protected, prolonging its service life.

[0016] Further, the inclined surface of the base is fixedly connected with a group of fixing plates, and the upper surface of each fixing plate is in contact with the bottom surface of the ladder block.

[0017] Through the above scheme, by setting the fixed plate, not only the contact area between the ladder block and the base is increased, thereby improving the stability of the overall structure, and through the slope design, the pressure generated during the use of the staircase can be effectively dispersed, the local stress concentration is reduced, and the durability and safety of the staircase are further ensured.

[0018] Further, the inside of each ladder block is provided with a reinforcing rib, and each reinforcing rib is an HRB400 threaded steel.

[0019] Through the above scheme, by setting the reinforcing rib, the structural strength and carrying capacity of the ladder block are significantly improved, however, the use of HRB400 threaded steel ensures the stability and durability of the reinforcing rib under heavy load, thereby making the staircase more solid and capable of adapting to frequent use and larger load.

[0020] Further, the outer surfaces of the two threaded rods are jointly sleeved with a connecting plate, and the outer surfaces of each threaded rod are threadedly connected with a nut.

[0021] Through the above scheme, by setting the connecting plate and the nut, not only the connection strength between the threaded rods is enhanced, but also the precise adjustment and fixation of each part of the staircase are realized through the cooperation of the threaded rods and the nuts.

[0022] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0023] The building staircase, through the combination of the telescopic rod and the compression spring, ensures that the connecting block can remain stable when subjected to external force, prevents the ladder block from loosening during use, and further enhances the fixing effect between the connecting block and the base through the setting of the positioning plate, thereby improving the stability and safety of the overall staircase. At the same time, due to the presence of the compression spring, when the ladder block is subjected to pressure, the spring can absorb part of the impact force, reducing the direct impact on the connecting block and prolonging the service life of the staircase, thereby forming a stable connection between each connecting block and the base, and ensuring that the connecting block can be quickly replaced when damaged.

Through the combination of the telescopic rod 17 and the compression spring 16, it is ensured that the connecting block 8 can remain stable when subjected to external force, and the loosening of the ladder block 2 in the use process is prevented. Through the setting of the positioning plate 18, the fixing effect between the connecting block 8 and the base 1 is further enhanced, thereby improving the stability and safety of the whole stair. At the same time, due to the existence of the compression spring 16, when the ladder block 2 is subjected to pressure, the spring can absorb part of the impact force, reducing the direct impact on the connecting block 8, prolonging the service life of the stair, so that a stable connection is formed between each connecting block 8 and the base 1, and at the same time, when the ladder block 2 is damaged, it can be quickly replaced.

[0032] Please refer to Figure 1 , Figure 3 and Figure 4The upper surface of each ladder block 2 is provided with a set of anti-skid grooves 6 arranged at equal distances, and the maximum depth of each anti-skid groove 6 is five millimeters. By providing the anti-skid grooves 6, the use safety of the ladder block 2 in a humid or oily environment is significantly improved, and the risk of slipping when a user goes up or down the stairs is reduced. The side of each set of positioning plates 18 away from each other is fixedly connected with a threaded rod 15. By providing the threaded rod 15, the stability of the positioning plates 18 after adjustment can be ensured by the threaded structure of the threaded rod 15, and the position deviation caused by vibration or external force is avoided, thereby ensuring the stability and safety of the overall structure of the stairs. The upper surface of each ladder block 2 is fixedly connected with a mounting seat 3, and the upper surface of each mounting seat 3 is provided with a set of fixed holes 4 arranged in a ring shape. By providing the mounting seat 3 and the fixed hole 4, additional support points are provided for the ladder block 2, the structural strength is enhanced, and other auxiliary facilities such as handrails or lighting equipment can be conveniently installed through the fixed hole 4, thereby further improving the practicability and safety of the stairs. The outer surface of each threaded rod 15 is sleeved with a rubber pad 11, and each set of rubber pads 11 is located on the left and right sides of the base 1. By providing the rubber pad 11, the vibration generated during the use of the stairs can be effectively absorbed, the noise is reduced, the threaded rod 15 is protected, and the service life is prolonged.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 The inclined surface of the base 1 is fixedly connected with a set of fixed plates 5, and the upper surface of each fixed plate 5 is in contact with the bottom surface of the ladder block 2. By providing the fixed plate 5, the contact area between the ladder block 2 and the base 1 is increased, the stability of the overall structure is improved, and the pressure generated during the use of the stairs can be effectively dispersed through the inclined surface design, the local stress concentration is reduced, and the durability and safety of the stairs are further ensured. The inside of each ladder block 2 is provided with a reinforcing rib 9, and each reinforcing rib 9 is made of HRB400 threaded steel. By providing the reinforcing rib 9, the structural strength and carrying capacity of the ladder block 2 are significantly improved.

By providing the connecting plate 10 and the nut 12, the connection strength between the threaded rods 15 is enhanced, and the precise adjustment and fixation of each part of the stairs are realized through the cooperation of the threaded rod 15 and the nut 12.

[0034] In the embodiment, the combination of the telescopic rod 17 and the compression spring 16 ensures that the connecting block 8 can remain stable when subjected to external force, prevents the ladder block 2 from loosening during use, and further enhances the fixing effect between the connecting block 8 and the base 1 through the positioning plate 18, thereby improving the stability and safety of the entire staircase. At the same time, due to the presence of the compression spring 16, when the ladder block 2 is subjected to pressure, the spring can absorb part of the impact force, reducing the direct impact on the connecting block 8 and prolonging the service life of the staircase, so that a stable connection is formed between each connecting block 8 and the base 1, and the damaged ladder block 2 can be quickly replaced.

[0035] The working principle of the above embodiment is as follows:

[0036] When the ladder block 2 needs to be replaced, first, unscrew the nut 12 and remove it, then remove the connecting plate 10 and the rubber pad 11 in turn, then compress the compression spring 16 by squeezing the threaded rod 15, so that the telescopic rod 17 moves inward, thereby driving the positioning plate 18 to move inward, then remove the positioning plate 18 from the through hole 14, and make the connecting block 8 disengage from the connecting groove 7, so that the connecting block 8 and the ladder block 2 can be easily removed, thereby replacing the damaged tread surface. Conversely, the effect of installing the ladder block 2 is achieved. This design not only simplifies the replacement process, but also ensures the stability and safety of the staircase during long-term use through the cooperation of the telescopic rod 17 and the compression spring 16.
