[0003] To address the aforementioned issues, existing patents offer solutions. However, most existing prefabricated staircases are integrated designs, lacking modular structures. This results in the need for large transport equipment during transportation due to the large size and weight of the components, increasing transportation costs and difficulties. Furthermore, the integrated prefabricated staircases require high-quality on-site construction conditions during installation, necessitating the use of large hoisting equipment, thus reducing installation efficiency.

[0004] Therefore, a prefabricated staircase that is easy to assemble is proposed. Utility Model Content

This solves the problem that most existing prefabricated staircases are integrated designs, lacking modular structures. As a result, during transportation, due to the large size and weight of the components, large transportation equipment is required, which increases transportation costs and difficulties. Furthermore, during installation, integrated prefabricated staircases have high requirements for on-site construction conditions and require large hoisting equipment, thus reducing installation efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated staircase that is easy to assemble, including a lower platform, wherein connecting mechanisms are provided on both sides of the rear top of the lower platform, and a combination mechanism is snapped onto the surface of the connecting mechanism;

[0007] The combined mechanism includes a lower stair section, an upper stair section, an upper platform, several stair segments, and stair beams.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The connection mechanism of this application, which uses the interlocking of the snap-fit ​​column and the snap-fit ​​sleeve, as well as the interlocking of the connecting rod and the connecting pipe, greatly simplifies the connection process between the components of the prefabricated staircase. This eliminates the need for complex operations and a large number of tools during on-site installation, allowing construction workers to quickly complete the assembly of components.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A prefabricated staircase that is easy to assemble includes a lower platform 1, with connecting mechanisms 2 on both sides of the rear top of the lower platform 1, and a combination mechanism 3 snapped onto the surface of the connecting mechanism 2.

[0028] The combined mechanism 3 includes a lower stair section 31, an upper stair section 32, an upper platform 33, several stair sections 34, and stair beams 35. The lower stair section 31 is engaged with the rear side of the top of the lower platform 1, the upper stair section 32 is engaged with the rear side of the top of the stair section 34, the upper platform 33 is engaged with the rear side of the top of the upper stair section 32, the stair section 34 is engaged with the rear side of the top of the lower stair section 31, and the stair beams 35 are engaged with the bottom of the lower stair section 31 and the stair section 34, respectively. The stair sections 34 are engaged with each other.

[0029] In this embodiment: by setting the lower platform 1 as the starting part of the staircase, a stable foundation support is provided for the entire staircase structure, ensuring that the staircase can withstand the loads of people and objects during use. Simultaneously, it supports and limits the lower stair section 31. The lower stair section 31, as the starting stair section, connects the lower platform 1 and the stair section 34, transferring the load of the lower platform 1 to the stair section 34, while also providing a transition for users from the lower platform 1 to the stair section 34. The upper stair section 32 connects the stair section 34 and the upper platform 33, transferring the load of the stair section 34 to the upper platform 33. 3. At the same time, it provides users with a transition from the stair section 34 to the upper platform 33. The upper platform 33 serves as the terminal platform of the staircase, bearing the load from the upper stair section 32 and providing users with a safe area for rest and changing direction. The stair section 34 serves as the intermediate stair section, connecting the lower stair section 31 and the upper stair section 32, transferring the load of the lower stair section 31 to the upper platform 33, and providing users with a walking passage from the lower platform 1 to the upper platform 33. The stair beam 35 can bear the weight and the load of the users and transfer these loads to the foundation structure of the building.

[0030] Specifically, such as Figure 3 , Figure 4 As shown, the connecting mechanism 2 includes a snap-fit ​​post 21, a snap-fit ​​sleeve 22, a sleeve 23, a reinforcing bar 24, a connecting rod 25, and a connecting pipe 26. The snap-fit ​​post 21 is fixedly connected to both sides of the top rear side of the lower platform 1 and both sides of the top rear side of the upper stair section 32.

[0031] Specifically, such as Figure 3 , Figure 4 As shown, the snap-fit ​​sleeves 22 are fixedly connected to both sides of the bottom front side of the lower stair section 31 and the bottom front side of the upper platform 33, respectively. The snap-fit ​​column 21 is engaged with the snap-fit ​​sleeve 22. The sleeves 23 are respectively opened on both sides of the lower platform 1, lower stair section 31, upper stair section 32, upper platform 33, stair section 34 and stair beam 35. The reinforcing bars 24 are fixedly connected to the inside of the sleeves 23.

[0032] Specifically, such as Figure 3 , Figure 4 As shown, the connecting rods 25 are fixedly connected to the two sides of the top inner side of the lower stair section 31 and the two sides of the top inner side of the stair section 34, respectively. The connecting pipes 26 are fixedly connected to the two sides of the bottom front side of the stair section 34 and the two sides of the bottom front side of the upper stair section 32, respectively. The connecting rods 25 and the connecting pipes 26 are engaged and snapped together.

[0033] In this embodiment: the snap-fit ​​post 21 provides snap-fit ​​positioning points for the snap-fit ​​sleeve 22. Through cooperation with the snap-fit ​​sleeve 22, the lower platform 1 can be quickly and accurately snapped with components such as the lower stair section 31 and the upper stair section 32, simplifying the stair assembly process and improving assembly efficiency. The snap-fit ​​sleeve 22 cooperates with the snap-fit ​​post 21 to provide positioning and guidance, ensuring the connection accuracy between stair components. The sleeve 23 provides installation space for the reinforcing bar 24. Through cooperation with the reinforcing bar 24, the structural strength and integrity of each stair component are enhanced. The reinforcing bar 24 can withstand the vertical and horizontal loads of the stair, improving the structural strength and stability of the stair. The connecting rod 25 cooperates with the connecting pipe 26 to connect the lower stair section 31 and the stair section 34, enhancing the connection strength and stability between each stair component. The connecting pipe 26 cooperates with the connecting rod 25 to connect and fix the stair components.

[0034] Specifically, such as Figure 5 As shown, anti-slip mats 4 are fixedly connected to the front side of the top of the lower platform 1, lower stair section 31, upper stair section 32, upper platform 33 and stair section 34. The anti-slip mats 4 are made of rubber material.

[0035] Specifically, such as Figure 6 As shown, the ladder beam 35 is made of reinforced concrete with steel bars 24, and the inner side of the ladder beam 35 is equipped with reinforcing bars 5.

[0036] In this embodiment: by setting the anti-slip mat 4, the friction between the user and the stair surface can be increased, preventing the user from slipping when going up and down the stairs and improving the safety of the stairs. By setting the anti-slip mat 4 to be made of rubber material, it has good elasticity and wear resistance, can adapt to different usage environments, and extend the service life of the anti-slip mat 4. By setting the stair beam 35 to be made of reinforced concrete material 24, the reinforced concrete material 24 has high strength and durability, can withstand large loads, and ensure the structural stability and safety of the stairs. By setting the reinforcing rib 5, the structural strength and deformation resistance of the stair beam 35 can be further enhanced, preventing the stair beam 35 from cracking or deforming during use, and improving the overall performance and service life of the stairs.

[0037] Specifically, such as Figure 4 As shown, both the connecting rod 25 and the connecting tube 26 are made of high-strength alloy material, and the surfaces of both the connecting rod 25 and the connecting tube 26 are coated with an anti-rust coating.

[0038] Specifically, such as Figure 5 As shown, the lower platform 1 and the top of the front side of the upper platform 33 are fixedly connected with anti-collision pads 6, which are made of silicone material.

[0039] In this embodiment: By setting both the connecting rod 25 and the connecting pipe 26 to be made of high-strength alloy material, the high-strength alloy material has high strength and toughness, and can withstand large external forces, ensuring the stability and reliability of the connection between the various components of the staircase. By setting an anti-rust coating, the connecting rod 25 and the connecting pipe 26 can be effectively prevented from rusting and corroding, extending their service life. By setting an anti-collision pad 6, it can play a buffering role when the user accidentally bumps into the stair platform, reducing the injury caused by the collision to the user and improving the safety of the staircase. By setting the anti-collision pad 6 to be made of silicone material, it has good elasticity and flexibility, can adapt to different collision situations, effectively absorb collision energy, and protect the safety of the user.

[0040] Working principle: First, the user transports the lower platform 1, lower stair section 31, upper stair section 32, upper platform 33, stair section 34, and stair beam 35 to the required installation location. Next, the user installs the lower platform 1 inside the building. Then, the user installs the stair beam 35 to the rear of the lower platform 1. After the stair beam 35 is installed, the user engages the snap-fit ​​sleeve 22 at the bottom front of the lower stair section 31 with the snap-fit ​​posts 21 on both sides of the top rear of the lower platform 1. Then, the user installs the stair beam 35 to the bottom of the lower stair section 31 and engages the connecting pipe 26 at the bottom front of the stair section 34 with the connecting rod 25 at the top rear of the lower stair section 31. Finally, the stair beams are installed sequentially. After the stairs are installed to the required height, the user connects the connecting pipe 26 at the bottom front of the upper stair section 32 to the connecting rod 25 at the top inner side of the top of the upper stair section 34, and connects the snap-fit ​​sleeve 22 at the bottom front of the upper platform 33 to the snap-fit ​​post 21 at the top rear of the upper stair section 32. At the same time, when installing the stairs, the user aligns the sleeves 23 on both sides of the lower platform 1, lower stair section 31, upper stair section 32, upper platform 33 and stair section 34 with the pre-embedded holes reserved in the wall, and connects the entire stairs to the wall by pouring concrete. Finally, after the concrete is poured, the user can check and adjust the stairs.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
