Description

Technical Field

[0001] This application belongs to the field of prefabricated construction technology, specifically an adjustable prefabricated staircase structure. Background Technology

[0002] Prefabricated construction is a new type of construction method that improves construction efficiency and quality by prefabricating components in a factory and then assembling them on the construction site. Precast slabs are an important component in prefabricated construction, typically made of concrete or other materials, and are characterized by standardization and modularity. Using precast slabs can significantly shorten the construction cycle, reduce labor costs, and to some extent reduce construction waste and resource waste. With the construction industry's increasing emphasis on sustainable development and green building, the application of prefabricated and modular construction is gradually becoming more widespread, becoming an important trend in modern architecture.

[0003] For example, application CN208039668U discloses an adjustable prefabricated staircase, including a channel steel with an opening on its upper surface. Stair treads are fixed to the channel steel, and each stair tread includes a first stair tread and a second stair tread, hinged together. Support rods are hinged to both sides of the first stair tread and connected to the sides of the second stair tread. Two first through holes are provided in the middle of the second stair tread for first bolts to pass through, securing the second stair tread to the channel steel. The first bolts pass through the openings and engage with nuts. This utility model provides a prefabricated staircase where, after the steel columns are erected, the stair treads are installed. The angle of the first stair tread is then adjusted to a horizontal position and fixed using support rods. This allows the staircase to be assembled at multiple angles and adjust the gap between each floor.

[0004] However, the application does not include a corresponding height adjustment feature, and the installation of the stairs is prone to difficulties due to manual errors. Utility Model Content

[0005] The purpose of this application is to provide an adjustable prefabricated staircase structure to solve the problem mentioned above that the lack of corresponding installation height adjustment makes the installation of stairs prone to difficulties due to manual errors.

[0006] The technical solution adopted in this application is as follows: An adjustable prefabricated staircase structure includes a connecting plate, side fixing holes are provided on the outer surfaces of both sides of the lower end of the connecting plate, a lower support seat is movably connected to the lower surface of the connecting plate, a fixing column is fixedly connected to the inner surface of the lower support seat corresponding to the side fixing holes, an anti-lifting strip is provided on the outer surface of the lower support seat, a rear support platform is fixedly connected to the outer surface of the lower support seat away from the anti-lifting strip, side limiting plates are fixedly connected to the outer surfaces of both sides of the lower support seat, and an insertion block is movably inserted into the side surface of the lower support seat.

[0007] By adopting the above technical solution, the connecting plate, lower support plate, and upper fixing plate are integrated into one piece, with built-in reinforced concrete to ensure sufficient stress. The connecting plate is the main position for connecting the various components of the staircase. The prefabricated effect is achieved through plug-in. The lower support base serves as the support component under the staircase. The insertion block structure on the other side corresponds to the other side of the lower support base. The fixing column is inserted into the corresponding position through the corresponding side fixing hole. The anti-lifting strip prevents the connecting plate from tilting and causing instability of the staircase.

The lower support plate is a single piece of plate without holes, resulting in stronger stress. The fixing nails on the upper fixing plate are inserted into the reference plate to ensure the fixation of the upper part of the staircase.

[0014] In a preferred embodiment, a reference plate is movably inserted into the lower surface of the upper fixing plate, and a side protection plate is provided on the outer surface of the reference plate.

[0015] By adopting the above technical solution, the upper end is integrated with the building support through the reference plate, forming a fixed support position for the upper staircase.

[0017] By adopting the above technical solution, concrete cement is poured into the pouring hole above the connecting plate and covered with the upper cover plate, and the sealing plate facilitates better sealing.

[0018] In a preferred embodiment, a stepped block is movably inserted into the inner surface of the connecting plate corresponding to the fixing groove. An insertion hole is provided on the upper surface of the stepped block, and an insertion hole is also provided on the upper surface of the sealing piece.

[0019] By adopting the above technical solution, the step block, as the main functional component of the staircase, makes it easier for people to walk, and the insertion hole facilitates the insertion and fixing of the railing post.

[0020] In a preferred embodiment, a railing post is movably inserted into the inner surface of the corresponding insertion hole of the step block, and a handrail strip is movably inserted into the upper surface of the railing post.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] 1. The connecting plate, lower support plate, and upper fixing plate are integrated into one piece, with built-in reinforced concrete to ensure sufficient stress. The connecting plate is the main position for connecting various components of the staircase. It achieves a prefabricated effect through plug-in. The lower support base serves as the support component under the staircase. The insertion block structure on the other side corresponds to the other side of the lower support base. The fixing column is inserted into the corresponding position through the corresponding side fixing hole.
