Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, specifically relating to a movable protective device for high-altitude construction operations. Background Technology

[0002] With the development of my country's metallurgical industry, steel structures are widely used in industrial buildings. Due to the difficulty of transportation after assembly, most of them are assembled and welded on-site, which makes construction difficult and the risk factor high.

[0003] To ensure the safety of on-site construction personnel, traditional high-altitude work protection mainly uses welded fixed guardrails. Welded fixed guardrails achieve safety protection by directly welding guardrails to the steel structure, but this method has drawbacks such as damage to the base material, immobility, and high cost. The high temperatures of welding can alter the metallographic structure of the base material, affecting the mechanical properties of the steel structure, and potentially creating hidden safety hazards, especially for load-bearing components.

[0004] Therefore, there is an urgent need to develop a high-altitude work protection device that can be quickly and non-destructively disassembled and assembled. Utility Model Content

[0005] This utility model provides a movable protective device for high-altitude construction operations, which solves the problems of existing protective devices damaging the base material and having poor adaptability.

[0006] This utility model provides a movable protective device for high-altitude operations, comprising: a first U-shaped slot, a second U-shaped slot, a steel pipe, a perforated steel plate, and bolts;

[0007] The first U-shaped slot and the second U-shaped slot are symmetrically arranged on both sides of the steel beam flange plate. A steel pipe is fixedly connected to the upper part of the first U-shaped slot, and the steel pipe is used to connect and fix the safety rope.

[0008] The tops of the first U-shaped slot and the second U-shaped slot are respectively fixedly connected with perforated steel plates. The holes of the perforated steel plates correspond to each other and are connected by screws. The two ends of the screws are fastened by nuts and washers.

[0009] Bolts are fixedly connected to both sides of the first U-shaped slot and the second U-shaped slot, forming a tight connection with the steel beam flange plate through the bolts.

[0010] Compared with the prior art, the advantages of this utility model are as follows: by adopting a symmetrically arranged U-shaped slot structure, non-destructive clamping and fixing of the steel beam flange plate is achieved; by connecting two U-shaped slots with screws to form a detachable clamping mechanism, damage to the base material caused by traditional welding methods is avoided; at the same time, bolt-assisted fixing is used to enhance the stability and safety of the device; the steel pipe, as the main support structure, provides a reliable protective barrier for high-altitude operations, realizes the rapid disassembly and reuse of the protective device, and significantly improves construction efficiency.

[0011] Furthermore, multiple retaining rings are symmetrically arranged on both sides of the steel pipe, which are used to secure the safety rope.

[0012] Furthermore, there are 4-8 retaining rings, evenly distributed on both sides of the steel pipe.

[0013] Furthermore, the length of the screw is adjustable, or it can be equipped with screws of various lengths to accommodate steel beam flanges of different widths.

[0014] Furthermore, the inner surfaces of the first U-shaped slot and the second U-shaped slot are provided with an anti-slip layer. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figure 1 This utility model provides a movable protective device for high-altitude construction operations, comprising: a first U-shaped slot 1, a second U-shaped slot 2, a steel pipe 7, a perforated steel plate 5, and bolts 4;

[0020] The first U-shaped slot 1 and the second U-shaped slot 2 are symmetrically arranged on both sides of the steel beam flange plate. A steel pipe 7 is fixedly connected to the upper part of the first U-shaped slot 1. The steel pipe 7 is used to connect and fix the safety rope.

[0021] The top of the first U-shaped slot 1 and the second U-shaped slot 2 are respectively fixedly connected with perforated steel plates 5. The holes of the perforated steel plates 5 correspond to each other and are connected by screws 6. The two ends of the screws 6 are fastened by nuts and washers.

[0022] Bolts 4 are fixedly connected to both sides of the first U-shaped slot 1 and the second U-shaped slot 2, forming a tight connection with the steel beam flange plate through the bolts 4.

[0023] The movable protective device for high-altitude operations provided by this utility model achieves non-destructive clamping and fixing of steel beam flange plates through a symmetrically arranged U-shaped slot structure; the two U-shaped slots are connected by screws 6 to form a detachable clamping mechanism, avoiding damage to the base material caused by traditional welding methods; at the same time, bolts 4 are used for auxiliary fixing, which enhances the stability and safety of the device; the steel pipe 7 serves as the main support structure, providing a reliable protective barrier for high-altitude operations, realizing the rapid disassembly and reuse of the protective device, and significantly improving construction efficiency.

[0024] Furthermore, multiple retaining rings 3 are symmetrically arranged on both sides of the steel pipe 7, and the retaining rings 3 are used to fix the safety rope.

[0025] The swivel 3 provides a dedicated connection point for the safety rope, making the safety protection system more comprehensive. By securing the safety rope at multiple points, impact force can be effectively dispersed, improving fall protection performance. At the same time, the swivel 3 makes the installation of the safety rope more standardized and convenient, avoiding the safety hazards caused by haphazard binding. This design greatly enhances the safety level of high-altitude operations.

[0026] Optionally, the number of retaining rings 3 is 4-8, evenly distributed on both sides of the steel pipe 7.

[0027] In one specific embodiment, the length of the screw 6 is adjustable, or multiple lengths of screw 6 can be provided to accommodate steel beam flanges of different widths. By adjusting the length of the screw 6 or providing multiple specifications, the same device can adapt to steel beam flanges of different sizes, greatly improving the device's versatility. This design solves the problem of poor applicability of traditional fixed-size protective devices, reducing equipment investment costs. At the same time, the adjustment method is simple and quick, facilitating rapid installation and use by on-site operators.

[0028] Optionally, the inner surfaces of the first U-shaped slot 1 and the second U-shaped slot 2 are provided with an anti-slip layer. The anti-slip layer further prevents the device from sliding or shifting during use; it improves the stability and reliability of the device, especially in operating environments with high vibration or wind; at the same time, the anti-slip layer also acts as a buffer, avoiding surface damage caused by direct metal-to-metal contact, and extending the service life of the device and the steel beam. Optionally, the anti-slip layer is a rubber pad layer.

[0029] In use, firstly, a perforated steel plate 5 and a steel pipe 7 are welded to the upper part of the first U-shaped groove 1. Four retaining rings 3 are installed on both sides of the steel pipe 7 for connecting the safety rope. Next, a perforated steel plate 5 is welded above the second U-shaped groove 2, and bolts 4 are welded to both sides for reinforcement with the flange plate. The first U-shaped groove 1 is placed on one side of the steel beam flange plate, and the second U-shaped groove 2 is placed on the other side of the steel beam flange plate and tightened. After aligning the two U-shaped grooves, they are bolted together using screws 6. Screws 6 of different lengths can be manufactured to match the U-shaped grooves, allowing for multiple uses and protection on steel beams of different specifications. A second movable protective device is installed at certain intervals, with two layers of safety ropes securing the two steel pipes 7 to the retaining rings 3 to prevent workers from falling.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
