Description

Technical Field

[0001] This utility model relates to the field of staircase construction technology, and in particular to a rapid-assembly staircase for prefabricated buildings. Background Technology

[0002] Prefabricated construction refers to a construction method in which building components are prefabricated in a factory and then transported to the construction site for assembly. This method typically includes prefabricated walls, floors, roofs, and other components, aiming to improve the construction efficiency and quality of buildings. Because a large number of components are prefabricated in the factory, prefabricated construction can significantly shorten the construction cycle on site. The factory production environment can ensure more stable component quality and reduce uncertainties on the construction site.

[0003] In existing technologies, prefabricated buildings also include the construction of stairs. In prefabricated buildings, the delivery time of buildings can be shortened by quickly assembling stairs. However, the existing prefabricated stair assembly process is complicated. Prefabricated stairs do not have positioning functions and require workers' experience or additional tools to assist in the assembly, which increases the labor intensity of workers and reduces the efficiency of stair assembly in prefabricated buildings. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing equipment, due to the lack of positioning function between prefabricated stairs, requires workers' experience or additional tools to assist in the construction. Therefore, this invention proposes a rapid construction staircase for prefabricated buildings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rapid-assembly staircase for prefabricated buildings, comprising a first staircase and a second staircase. The top of the first staircase has two strip grooves. A spring is fixedly installed on one side of the inner wall of each of the two strip grooves. A T-shaped insert is fixedly installed on one side of the outer wall of each of the two springs. The outer walls of the two T-shaped inserts are movably embedded in the interior of the two strip grooves. A handle-equipped pull rod is fixedly installed on one side of the outer wall of each of the two T-shaped inserts. Two positioning blocks are fixedly installed on one side of the outer wall of the second staircase. The outer walls of the two positioning blocks are movably inserted into the interior of the two strip grooves. A positioning hole is provided on one side of the outer wall of each of the two positioning blocks. The outer walls of the two T-shaped inserts are movably inserted into the interior of the two positioning holes.

[0006] Preferably, two protective covers are fixedly installed on the top of the first staircase.

[0007] Preferably, two round holes are provided on one side of the outer wall of the first staircase, and the outer walls of the two pull rods are movably inserted into the two round holes.

[0008] Preferably, a strip plate is fixedly installed at the bottom of the second staircase.

[0009] Preferably, the top of the first staircase has a strip-shaped hole, and the outer wall of the strip plate is movably inserted into the inside of the strip-shaped hole.

[0010] Preferably, four fixing holes are provided on one side of the outer wall of the strip plate, and four limiting holes are provided on the other side of the outer wall of the first staircase.

[0011] Preferably, the inner walls of the four fixing holes are threaded with bolts, and the outer walls of the four bolts are movably inserted into the four limiting holes.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, two T-shaped inserts are moved by two handle rods, causing them to move within two strip grooves. Simultaneously, two springs are compressed, placing the inserts in a compressed state. Then, when the two positioning blocks on the second staircase are inserted into the two strip grooves, the two handle rods are released. Under the action of the two springs, the two T-shaped inserts are moved and inserted into the two positioning holes. This initially limits the second staircase to the first staircase, achieving a positioning effect. This facilitates subsequent fixing by workers, reduces their labor intensity, and improves the efficiency of staircase construction in prefabricated buildings.

[0014] 2. In this utility model, when the two positioning blocks are limited in the two strip grooves, the strip plate is just inserted into the strip hole. Then, through the action of four bolts, it passes through the four limiting holes and is threaded into the four fixing holes, so that the second staircase can be installed on the first staircase, thus realizing the rapid installation of the prefabricated staircase.

[0021] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a quick-assembly staircase for prefabricated buildings, including a first staircase 1 and a second staircase 2. The top of the first staircase 1 has two strip grooves 3. Springs 4 are fixedly installed on one side of the inner wall of each of the two strip grooves 3. T-shaped inserts 5 are fixedly installed on one side of the outer wall of each of the two springs 4. The outer walls of the two T-shaped inserts 5 are movably embedded in the interior of the two strip grooves 3. A handle-type pull rod 6 is fixedly installed on one side of the outer wall of each of the two T-shaped inserts 5. Two positioning blocks 7 are fixedly installed on one side of the outer wall of the second staircase 2. The outer walls of the two positioning blocks 7 are movably inserted into the interior of the two strip grooves 3. Positioning holes 8 are opened on one side of the outer wall of each of the two positioning blocks 7. The outer walls of the two T-shaped inserts 5 are movably inserted into the interior of the two positioning holes 8.

[0024] The overall effect of Embodiment 1 is that when a prefabricated staircase needs to be quickly assembled in a prefabricated building, the prefabricated staircases are a first staircase 1 and a second staircase 2, and the second staircase 2 needs to be quickly assembled on the first staircase 1. At this time, two handle rods 6 pass through two round holes 10 and drive two T-shaped inserts 5 to move within two strip grooves 3. Since springs 4 are installed between the two T-shaped inserts 5 and the strip grooves 3, the two springs 4 can be compressed. Then, two positioning blocks 7 installed on one side of the outer wall of the second staircase 2 are inserted into the two strip grooves 3. Loosen the two levers 6 with handles. Under the action of the two springs 4, they will drive the two T-shaped inserts 5 to move and pass through the positioning holes 8 opened on the two positioning blocks 7. Then, they will be inserted into the inner walls of the first stair 1 and the two strip grooves 3. This will initially limit the second stair 2 to the two strip grooves 3 and the first stair 1, achieving a positioning effect. No external tools are needed for the workers to assist in the installation, ensuring that the installation between the first stair 1 and the second stair 2 is fast and accurate. This will reduce the labor intensity of the workers and improve the efficiency of building stairs in prefabricated buildings.

[0025] Example 2: As Figures 2-4 As shown, two protective covers 9 are fixedly installed on the top of the first staircase 1. Two round holes 10 are opened on one side of the outer wall of the first staircase 1, and the outer walls of the two handle rods 6 are movably inserted into the two round holes 10. A strip plate 11 is fixedly installed at the bottom of the second staircase 2. A strip hole 12 is opened on the top of the first staircase 1, and the outer wall of the strip plate 11 is movably inserted into the strip hole 12. Four fixing holes 13 are opened on one side of the outer wall of the strip plate 11, and four limiting holes 14 are opened on the other side of the outer wall of the first staircase 1. Bolts 15 are threadedly connected to the inner surface of the four fixing holes 13, and the outer walls of the four bolts 15 are movably inserted into the four limiting holes 14.

[0026] The effect achieved by the entire embodiment 2 is that, through the action of the two protective covers 9, and the fact that the two protective covers 9 are always located above the two strip grooves 3, it effectively prevents foreign objects from falling into the two strip grooves 3 during the construction process, thus affecting the smooth movement of the two springs 4. Since the first stair 1 has a strip hole 12, and the bottom of the second stair 2 has a strip plate 11 fixedly installed, when the second stair 2 is initially positioned in the two strip grooves 3 by the two positioning blocks 7, its strip plate 11 is just inserted into the strip hole 12, and the four fixing holes 13 opened on the strip plate 11 correspond to the four limiting holes 14 opened on the other side of the outer wall of the first stair 1. Thus, through the action of the four bolts 15, it passes through the four limiting holes 14 and is threaded into the four fixing holes 13, thereby allowing the second stair 2 to be installed together with the first stair 1, thus realizing the rapid installation of the prefabricated staircase.

[0027] Working principle: First, in the prefabricated construction process, the prefabricated staircase needs to be assembled, and the second staircase 2 needs to be installed on the first staircase 1. At this time, two T-shaped inserts 5 are moved along the two round holes 10 by two handle rods 6, causing them to compress the two springs 4. Then, the second staircase 2 with two positioning blocks 7 is placed in the corresponding position on the first staircase 1, and the two positioning blocks 7 are inserted into the two strip slots 3. At this time, the strip plate 11 installed at the bottom of the second staircase 2 is also inserted into the strip hole 12 opened at the top of the first staircase 1. Then, the two handle rods 6 are released, and under the action of the two springs 4, they are moved... Two T-shaped inserts 5 move and are inserted into the positioning holes 8 opened on the two positioning blocks 7, and simultaneously inserted into one side of the inner wall of the two strip grooves 3, thus initially limiting the second stair 2 on the first stair 1, which has a positioning function and does not require the assistance of external tools for installation. Then, through the action of four bolts 15, they pass through the four limiting holes 14 and are threaded into the four fixing holes 13, so that the second stair 2 can be quickly installed on the first stair 1. This realizes the rapid installation between the two prefabricated staircases, reduces the labor intensity of workers, and thus improves the efficiency of building staircases in prefabricated buildings.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
