Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a movable, modular protective structure for the edge of a staircase. Background Technology

[0002] During the construction of staircases in building projects, edge protection is a core aspect of ensuring the safety of construction workers. However, existing protection methods have many problems that urgently need to be addressed:

[0003] 1. Lack of protection during construction gaps: In the staircase renovation process, temporary protective facilities must be removed before the installation of formal guardrails, and there is a certain construction interval between the two. During this gap, the edges of the staircase are completely unprotected, and construction workers, inspectors, or other relevant personnel are very likely to fall due to accidental slips, posing a serious threat to their lives.

[0004] 2. Conflicts Regarding Safety Measures During Staircase Tread Laying: To ensure the flatness, integrity, and quality of the tiled surface during staircase tread laying, the existing edge protection must be removed. Otherwise, the protective structure will hinder the tiling process and subsequent leveling and compaction. However, after the protection is removed, the staircase edges lose effective protection, drastically increasing the risk of falls for workers during tiling operations or when moving between stair flights, posing a significant safety hazard during construction.

[0005] 3. Inefficiency and Hidden Dangers of Traditional Protection Methods: Currently, the traditional stair edge protection methods commonly used in the industry require repeated erection and dismantling operations according to the construction schedule. This method not only generates a large amount of repetitive labor, leading to increased labor costs, but also affects overall construction efficiency due to the frequent erection work occupying construction time. More importantly, if the erection of protection is not timely due to tight schedules or improper personnel allocation, the stair edge will remain unprotected for extended periods, further amplifying the safety risk of falls and failing to meet the requirements of modern construction projects for safe and efficient construction. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a mobile, modular protective structure for stair edges. This structure overcomes the defects of traditional stair edge protection construction, reduces repetitive labor, lowers construction costs, and eliminates safety hazards. Moreover, it is easy to assemble and move, and can be quickly put into use and transferred, thereby improving construction efficiency.

[0007] To solve the above-mentioned technical problems, this utility model provides a mobile, modular protective structure for stair edges, comprising telescopic columns, steel plates, steel wire ropes, and butterfly fasteners. The front of the steel plate is covered with steel burrs, and the back of the steel plate is located at both ends of the telescopic columns. The telescopic columns have through holes spaced apart along their length. The telescopic columns are spaced apart on the surface of the upper and lower concrete components along the stair edge. The steel wire ropes pass through the through holes of each telescopic column in sequence to form a guardrail. The butterfly fasteners are fastened to the steel wire ropes and are located on both sides of the through holes of the telescopic columns.

[0008] Furthermore, the back of the steel plate is provided with a hinge seat, which is located at both ends of the telescopic column via pins.

[0009] Furthermore, the through holes of the telescopic column are spaced 600mm apart from bottom to top.

[0010] Furthermore, the telescopic column includes multiple connecting rods connected by threads.

[0011] Because this utility model employs the aforementioned technical solution for a mobile, modular protective structure for stair edges, the steel plate of this structure has steel burrs laid flat on its front side, and steel plates are positioned at both ends of telescopic columns on the back side. The telescopic columns have through holes spaced along their length. These columns are erected at intervals along the stair edge direction on the upper and lower concrete components of the stair edge. Steel wire ropes pass sequentially through the through holes of each telescopic column to form a guardrail. Butterfly fasteners are secured to the steel wire ropes and are located on both sides of the through holes of the telescopic columns. This structure overcomes the shortcomings of traditional stair edge protection construction, reduces repetitive labor, lowers construction costs, and eliminates safety hazards. Furthermore, it is easy to assemble and move, allowing for rapid deployment and relocation, thus improving construction efficiency. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0013] Figure 1 This is a schematic diagram of the movable, assembled protective structure for the edge of a staircase according to this utility model;

[0014] Figure 2 This is a schematic diagram showing the connection between the telescopic column and the steel plate in this structure. Detailed Implementation

[0015] Implementation, for example Figure 1 and Figure 2As shown, the movable, modular protective structure for the edge of a staircase includes a telescopic column 1, a steel plate 2, a steel wire rope 3, and a butterfly fastener 4. The front of the steel plate 2 is covered with steel burrs 21, and the back of the steel plate 2 is located at both ends of the telescopic column 1. The telescopic column 1 has through holes 11 spaced along its length. The telescopic column 1 is spaced along the edge of the staircase and is erected on the surface of the upper and lower concrete components 5 at the edge of the staircase. The steel wire rope 3 passes through the through holes 11 of each telescopic column 1 to form a guardrail. The butterfly fastener 4 is fastened to the steel wire rope 3 and is located on both sides of the through holes 11 of the telescopic column 1.

[0016] Preferably, the back of the steel plate 2 is provided with a hinge seat 22, which is located at both ends of the telescopic column 1 via a pin 23. The orientation of the steel plate can be adjusted by the cooperation between the hinge seat and the pin.

[0017] Preferably, the through holes 11 of the telescopic column 1 are spaced 600mm apart from bottom to top.

[0018] Preferably, the telescopic column 1 includes multiple connecting rods connected by threads 12.

[0019] In practical applications, the length of the telescopic column is adjusted using multi-section connecting rods based on the actual height of the staircase edge. The steel burrs on both ends are adjusted at an angle via hinged seats and pins to ensure good contact with the concrete surface. The length of the telescopic column is then fixed to ensure its stability. Other telescopic columns are installed sequentially according to the required protection length, ensuring reasonable spacing between them.

[0020] Thread steel wire ropes through the through holes at 600mm and 1200mm on each telescopic post to form a two-layer guardrail. Install butterfly-shaped fixing buckles on the steel wire ropes on both sides of each telescopic post and tighten them to prevent the steel wire ropes from slipping. This will provide protection for the staircase edge.

[0021] When it is necessary to move the protective structure or a telescopic column, loosen the butterfly fastener, shorten the telescopic column, and then transfer the components to the new position. Reassemble and use them according to the steps above.

[0022] This structure effectively mitigates fall risks, providing reliable protection in various unprotected scenarios during stair construction, such as construction gaps after temporary protection is removed and during stair tread tiling, preventing falls. It reduces costs by eliminating the traditional practice of repeatedly erecting and dismantling edge protection, minimizing redundant labor and thus lowering construction costs. It improves safety and efficiency: the elimination of repeated erection eliminates untimely erection and associated safety hazards; its easy assembly and relocation allow for rapid deployment and transfer, improving construction efficiency. The installation is stable and reliable, with the columns secured by friction between steel burrs and the concrete surface, and butterfly-shaped fasteners preventing wire rope slippage, ensuring the stability and reliability of the entire protection system. It is highly flexible, employing a mobile assembly design that allows for flexible adjustment and assembly to suit different stair lengths and widths, adapting to various construction scenarios.
