Abstract
Description
Technical Field
[0001] This utility model relates to the field of staircase technology, specifically to an end protection structure for a steel structure pedestrian staircase. Background Technology
[0002] In some factories, the second floor is often used as a warehouse. To facilitate the flow of personnel and materials between the first and second floors, steel-structured staircases are usually installed. However, due to limited space in the factory area, these staircases are often designed with a steep slope and a long vertical distance between each step, especially the distance between the first step and the ground.
[0003] Traditional staircases typically lack effective safety features at the starting point, making it very difficult for workers to ascend from the ground to the first step. Furthermore, when descending from the first step back to the ground, the lack of hand support increases the risk of missteps and falls. This not only affects work efficiency but also poses a potential threat to worker safety. Therefore, we propose a steel structure staircase end protection structure to address these issues.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0023] This application provides an end protection structure for a steel structure pedestrian staircase, primarily addressing the problem that existing pedestrian staircases often lack effective protection at the starting point, making it very difficult for workers to descend from the ground to the first step. Furthermore, when descending from the first step back to the ground, the lack of effective hand support increases the risk of missteps or falls, impacting work efficiency and posing a potential threat to worker safety. The application provides the following technical solution, which will be discussed in conjunction with... Figures 1-4Please provide a detailed explanation:
[0024] An end protection structure for a steel structure pedestrian staircase, comprising:
[0025] The support frame 1 has support plates 2 fixed on both sides of its top. The support plates 2 are in the shape of a zigzag line, and the end of the support plate 2 away from the support frame 1 is in contact with the ground.
[0026] Guardrail 3 and step plate 4: Guardrail 3 is fixed to the top of support plate 2, and step plate 4 is evenly spaced between support plates 2;
[0027] The U-shaped extension arm 5 is detachably installed on the lower side of the guardrail 3, and the U-shaped extension arm 5 has a curved structure.
[0028] Connector 6 is located on the lower side of guardrail 3 and is used to connect guardrail 3 and U-shaped extension arm 5.
[0029] Workflow and principle explanation:
[0030] Before use, fix the U-shaped extension arm 5 to the lower side of the guardrail 3 using the connector 6. Note that the U-shaped extension arm 5 should generally be bent outwards.
[0031] When climbing stairs: When staff approach the beginning of the stairs, they can hold the U-shaped extension arm 5 and use the force it provides to help them climb the first step. Because the U-shaped extension arm 5 has a curved structure, it can adapt to staff of different heights and climbing habits and provide a stable force point.
[0032] When descending the stairs: staff can hold onto the U-shaped extension arm 5 again as a support point to prevent them from slipping or falling due to lack of effective hand support. The importance of the U-shaped extension arm 5 is especially evident when returning to the ground from the first step.
[0033] The end protection structure of this steel structure staircase provides workers with additional leverage and support points by setting a U-shaped extension arm 5 at the beginning of the staircase. This effectively solves the problem of lack of protection at the beginning of traditional staircases. As the process of going up and down the stairs is safer and more convenient, workers can complete material handling and personnel movement tasks more efficiently, improving overall work efficiency. It is highly practical and worthy of widespread application and promotion.
[0034] like Figure 2As shown, in some embodiments, the connector 6 includes a rectangular frame 601 fixed to the bottom side of the guardrail 3. Connecting pipes 602 are embedded on both the upper and lower sides of the rectangular frame 601. The upper connecting pipe 602 is connected to the guardrail 3. The two ends of the U-shaped extension arm 5 are slidably embedded inside the connecting pipe 602. The inner top wall and inner bottom wall of the rectangular frame 601 are threaded with locking bolts 603 extending into the connecting pipe 602. More specifically, when the worker needs to install and fix the U-shaped extension arm 5, first loosen the locking bolts 603 so that the U-shaped extension arm 5 can enter the connecting pipe 602, and then tighten the locking bolts 603 to firmly fix the U-shaped extension arm 5 on the connecting pipe 602.
[0035] like Figure 2 As shown, in some embodiments, the surface of the U-shaped extension arm 5 is covered with a rubber sleeve. More specifically, the surface of the rubber sleeve has a certain texture and roughness, which can increase the friction when the worker holds the U-shaped extension arm 5, prevent the worker from losing balance due to slipping during climbing or descending, and improve overall safety. The rubber sleeve is soft and has a certain degree of elasticity, which can relieve the pressure when the worker holds the U-shaped extension arm 5. Compared with bare metal, the rubber sleeve provides a more comfortable grip experience and reduces hand fatigue caused by prolonged use. In addition, the rubber sleeve is usually made of wear-resistant, aging-resistant, acid and alkali-resistant rubber material to ensure its long-term performance.
[0036] like Figure 2 As shown, in some embodiments, a reinforcing rod 501 is provided in the middle of the U-shaped extension arm 5. More specifically, when workers climb or go downstairs, the U-shaped extension arm 5 needs to withstand a certain amount of tension or pressure. The reinforcing rod 501 can effectively disperse these forces and prevent the U-shaped extension arm 5 from deforming or being damaged due to excessive force. In addition to enhancing the structural strength and stability, the reinforcing rod 501 helps to extend the service life of the U-shaped extension arm 5. The connection between the reinforcing rod and the U-shaped extension arm 5 is usually achieved by welding or bolting, which are strong and reliable methods. This connection method can ensure that the reinforcing rod 501 and the U-shaped extension arm 5 form a tight integral structure and jointly bear the external force.
[0037] like Figure 2 As shown, in some embodiments, the step plate 4 is L-shaped, and its bottom plate has anti-slip texture on the top. More specifically, the L-shaped design makes the contact area between the step plate 4 and the support plate 2 larger, which can form a stronger weld during welding and further improve the strength of the connection. The main function of the anti-slip texture is to increase the friction of the surface of the step plate 4 and prevent workers from slipping when climbing or going downstairs. The anti-slip texture usually adopts a raised or recessed texture design, which can effectively resist the slipping of the soles of the feet.
[0038] like Figure 2As shown, in some embodiments, when the U-shaped extension arm 5 bends inward, the two U-shaped extension arms 5 abut against each other on the side away from the guardrail 3. More specifically, in some special cases, staff need to prevent people from climbing the stairs. At this time, the U-shaped extension arms 5 can be fixed in an inward bending posture. Since the two U-shaped extension arms 5 abut against each other on the side away from the guardrail 3, together with the reinforcing rod 501, the two U-shaped extension arms 5 are like a door, which can prevent people from climbing the stairs.
[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
