Description

Technical Field

[0001] This application relates to the field of architectural decoration technology, specifically an installation structure for prefabricated stair railings. Background Technology

[0002] During construction, staircases serve as crucial passageways for workers, necessitating the installation of temporary stair railings to ensure safety. Currently, temporary stair railings are mostly prefabricated structures installed on stair treads, primarily consisting of posts and multiple layers of handrails. These components are assembled and secured using connectors and bolts. This prefabricated structure is characterized by its simplicity and ease of transport.

[0003] However, the existing prefabricated stair railings, which use bolts for fixing, have significant shortcomings: during installation or disassembly, workers need to repeatedly tighten the screws to assemble and disassemble the components, and screws are very likely to fall to the ground during this process. These scattered screws can not only cause workers to slip and trip, but also affect the working environment of the construction area, posing potential safety hazards and failing to meet the needs of efficient and safe use on construction sites.

[0004] Therefore, this application provides an installation structure for prefabricated stair railings to solve the above-mentioned problems. Utility Model Content

[0005] This application provides an installation structure for prefabricated stair railings, aiming to solve the problems mentioned in the background art, such as the use of bolts for fixing existing prefabricated stair railings, the need for repeated tightening of screws during installation and disassembly which can easily lead to screws falling off, posing safety hazards, and low assembly and disassembly efficiency.

[0006] To achieve the above objectives, this application provides the following technical solution: an installation structure for a prefabricated stair railing, comprising a post for fixed installation on a stair tread, a multi-layer handrail disposed on the post, and an assembly assembly for fixedly installing the handrail on the post; the assembly assembly comprises a fixing sleeve fixedly fitted on the post, an insert plate fixedly connected to the end of the handrail, a guide plate disposed at the end of the insert plate away from the handrail, an arc-shaped plate fixedly disposed on the side of the guide plate and the insert plate, and an arc-shaped groove formed in the fixing sleeve for fitting the arc-shaped plate; wherein the convex surface of the arc-shaped plate is arranged outward. During installation, when one end of the guide plate is inserted into the fixed sleeve, the handle is pushed further into the fixed sleeve, causing the guide plate, arc plate, and insert plate to be inserted into the fixed sleeve in sequence. When the arc plate is in the arc groove inside the fixed sleeve, the arc plate is squeezed by the action of the wedge block, causing the arc plate to detach from the arc groove. When the wedge block moves along the arc groove to the end of the passage, the wedge block is inserted into the passage by the elastic action of the arc plate.

[0007] Preferably, to facilitate the insertion of the guide plate, arc-shaped plate, and insert plate into the fixed sleeve, the end of the guide plate away from the arc-shaped plate is tapered. This reduces the resistance to inserting the guide plate, arc-shaped plate, and insert plate into the fixed sleeve, reduces the difficulty of installation, and further improves installation efficiency.

[0008] Preferably, the arc-shaped plate is an elastic steel plate. This enhances the fit between the arc-shaped plate and the arc-shaped groove, improves the connection stability between the handrail and the column, and provides a basis for deformation recovery during subsequent disassembly, ensuring a smooth disassembly and assembly process.

[0009] Preferably, to ensure the stability of the connection between the handrail and the fixed sleeve: a wedge block is fixedly connected to the arc-shaped plate, and the fixed sleeve has an opening for fitting the wedge block. This forms a secondary locking structure, preventing the handrail from loosening during use, significantly improving connection stability and safety, and avoiding accidents when construction workers pass through.

[0010] Preferably, for ease of disassembly: an arc-shaped push plate is fixedly connected to the outer side of the through-hole on the fixed sleeve, and a pressing rod fixedly connected to the arc-shaped push plate is inserted into the through-hole. The cooperation between the arc-shaped push plate and the pressing rod facilitates the removal of the inclined block from the through-hole, allowing disassembly to be completed without the need for additional tools. This simplifies the disassembly process, saves disassembly time, and avoids damage to the components during disassembly, ensuring the reusability of the components.

[0011] Preferably, the posts are fixedly connected to the stair treads using expansion bolts or chemical anchors. This ensures a firm and reliable connection between the posts and stair treads, improving the overall load-bearing capacity and stability of the prefabricated stair railing and providing safety for construction workers.

[0012] This application utilizes the design of the assembly components, through the cooperation of the arc plate and the arc groove in the fixing sleeve, to fix the end of the handrail to the column, replacing the traditional welding or screw fixing method. It eliminates the need to repeatedly tighten the screws, avoids the safety hazards caused by the screws falling off, and greatly improves the installation and disassembly efficiency of the handrail and the column. The components can be reused in multiple projects, which meets the requirements of sustainable development.

[0013] This application utilizes the interlocking of the inclined block on the arc plate with the through-hole on the fixed sleeve to form a secondary locking structure, preventing the handrail from becoming loose during use, significantly improving connection stability and safety, and avoiding accidents when construction workers pass through.

[0014] This application facilitates the removal of the inclined block from the opening by using the cooperation of the arc-shaped push plate and the extrusion rod. Disassembly can be completed without the need for additional tools, simplifying the disassembly process, saving disassembly time, and avoiding damage to components during disassembly, thus ensuring the reusability of the components.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0018] This embodiment provides an installation structure for a prefabricated stair railing, such as... Figure 1-4As shown, the installation structure includes a post 1 for fixing to the stair tread, a multi-layer handrail 2 set on the post 1, and an assembly component 3 for fixing the handrail 2 to the post 1. The assembly component 3 includes a fixing sleeve 31 fixedly fitted onto the post 1, an insert plate 32 fixedly connected to the end of the handrail 2, a guide plate 33 set at the end of the insert plate 32 away from the handrail 2, an arc-shaped plate 34 fixedly set on the side of the guide plate 33 and the insert plate 32, and an arc-shaped groove 35 formed in the fixing sleeve 31 for fitting the arc-shaped plate 34; wherein the convex surface of the arc-shaped plate 34 is set outward. This method replaces traditional welding or screw fixing methods, eliminating the need for repeated screw tightening, avoiding safety hazards caused by loose screws, significantly improving the installation and disassembly efficiency of the handrail 2 and post 1, and allowing the component to be reused in multiple projects, meeting the requirements of sustainable development. During installation, when one end of the guide plate 33 is inserted into the fixed sleeve 31, the handle 2 is pushed further into the fixed sleeve 31, so that the guide plate 33, the arc plate 34 and the insert plate 32 are inserted into the fixed sleeve 31 in sequence. When the arc plate 34 is in the arc groove 35 in the fixed sleeve 31, the arc plate 34 will be squeezed by the inclined block 341, so that the arc plate 34 will be separated from the arc groove 35. When the inclined block 341 moves along the arc groove 35 to the port of the through 311, the inclined block 341 is inserted into the through 311 by the elastic action of the arc plate 34.

[0019] To facilitate the insertion of the guide plate 33, the arc-shaped plate 34, and the insert plate 32 into the fixed sleeve 31, the end of the guide plate 33 away from the arc-shaped plate 34 is tapered. This reduces the resistance to insertion of the guide plate 33, the arc-shaped plate 34, and the insert plate 32 into the fixed sleeve 31, reducing the difficulty of installation and further improving installation efficiency. The tapered end guides the guide plate 33, along with the arc-shaped plate 34 and the insert plate 32, into the fixed sleeve 31 accurately and smoothly, avoiding jamming during insertion.

[0020] The curved plate 34 is made of elastic steel. This enhances the fit and conformity between the curved plate 34 and the curved groove 35, improving the connection stability between the handrail 2 and the column 1. It also provides a basis for deformation recovery during subsequent disassembly, ensuring smooth assembly and disassembly. The elastic steel material gives the curved plate 34 deformable characteristics, allowing it to fit tightly against the contour of the curved groove 35 during insertion. It can also undergo elastic deformation under pressure and quickly return to its original position after being released from constraint.

[0021] To ensure the stability of the connection between the handrail 2 and the fixed sleeve 31, an inclined block 341 is fixedly connected to the arc plate 34, and the fixed sleeve 31 has a through-hole 311 for fitting the inclined block 341. This forms a secondary locking structure, preventing the handrail 2 from loosening during use, significantly improving connection stability and safety, and preventing accidents when construction workers pass through. During installation, pushing the handrail 2 causes the guide plate 33, arc plate 34, and insert plate 32 to be inserted into the fixed sleeve 31 in sequence. After the arc plate 34 enters the arc groove 35, the inclined block 341 presses the arc plate 34 to disengage it from the arc groove 35 until the inclined block 341 moves to the port of the through-hole 311. The arc plate 34 then resets under elastic action, causing the inclined block 341 to be inserted into the through-hole 311 for locking and fixing.

[0022] For easy disassembly: an arc-shaped push plate 4 is fixedly connected to the outer side of the through-hole 311 on the fixed sleeve 31, and a pressing rod 41 fixedly connected to the arc-shaped push plate 4 is inserted into the through-hole 311. The cooperation between the arc-shaped push plate 4 and the pressing rod 41 facilitates the removal of the inclined block 341 from the through-hole 311, and disassembly can be completed without the need for additional tools, simplifying the disassembly operation process, saving disassembly time, and avoiding damage to components during disassembly, thus ensuring the reusability of components. During disassembly, pressing the arc-shaped push plate 4 moves the pressing rod 41 fixedly connected to it within the through-hole 311. The pressing rod 41 pushes the inclined block 341 out of the through-hole 311. After the locking state is released, the insert plate 32, guide plate 33 and arc-shaped plate 34 can be removed from the fixed sleeve 31.

[0023] Post 1 is fixedly connected to the stair tread using expansion bolts or chemical anchors. This ensures a secure and reliable connection between post 1 and the stair tread, enhancing the overall load-bearing capacity and stability of the prefabricated stair railing and providing safety for construction workers. The tightening properties of expansion bolts or chemical anchors stably fix post 1 to the stair tread, providing a solid installation foundation for handrail 2 and other components, preventing post 1 from shaking or shifting.

[0024] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0025] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
