Description

A safety rope attachment device based on an H-shaped steel beam Technical Field

[0001] The embodiments disclosed herein relate to the field of safety rope accessories technology, specifically to a safety rope attachment device based on an H-shaped steel beam. Background Technology

[0002] In modern architecture and various engineering constructions, H-beams have been widely used due to their unique advantages. Named for their cross-sectional shape resembling the capital Latin letter H, H-beams, also known as wide-flange I-beams, offer numerous significant advantages over traditional reinforced concrete structures. These include excellent seismic performance, effectively resisting damage to building structures from natural disasters such as earthquakes; high component strength, capable of withstanding large loads, and lightweight construction, significantly reducing foundation work and construction costs; large spans and small internal structural footprint, increasing usable area; and ease of dry construction, reducing noise pollution and contributing to environmental protection.

[0003] H-beams are used in a wide range of applications, including beams and columns in civil building steel structures, load-bearing supports in industrial building steel structures, pipe supports, transport bridge supports, mine supports, and even steel piles and support structures in underground engineering, supports for industrial equipment in petrochemical and power industries, components of large-span steel bridges, and offshore oil platforms.

[0004] During construction projects, especially when working at heights, ensuring the safety of construction workers is of paramount importance. Safety ropes, as an important safety protection device, are widely used to protect the personal safety of construction workers when working at heights and to prevent injuries or fatalities caused by accidental falls. Construction workers must attach their safety ropes to reliable devices to ensure safety during the work process.

[0005] However, existing safety rope attachment devices based on H-beams have many problems. Some traditional devices require tedious measurement and positioning work during installation, which consumes a lot of time and manpower and is extremely inconvenient. Some devices that use support columns to fix the safety rope require precise measurement of the position of the support column on the H-beam to ensure that the suspension height and angle of the safety rope are appropriate. This process is not only complicated to operate, but also prone to safety errors that cause the safety rope attachment to fail to meet safety standards. Summary of the Invention

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a safety rope attachment device based on an H-shaped steel beam. This solves the technical problem that some traditional devices in the prior art require cumbersome measurement and positioning work during installation, which consumes a lot of time and manpower and makes the installation process extremely inconvenient. Some devices that use support columns to fix the safety rope require precise measurement of the position of the support column on the H-shaped steel beam during installation to ensure that the suspension height and angle of the safety rope are appropriate.

[0007] According to one aspect, at least one embodiment of this disclosure provides a safety rope attachment device based on an H-beam, comprising:

[0008] A beam body, on which a positioning clamp is provided;

[0009] A drive clamping assembly is disposed on the positioning clamp;

[0010] A rust-proof and protective component is disposed on the upper end face of the positioning clamp;

[0011] The drive clamping assembly includes a clamping groove, which is formed on the side wall of the positioning clamp. A force-receiving plate is provided on the inner bottom surface of the clamping groove. The force-receiving plate is in contact with the beam. A drive bolt is provided on the upper end face of the positioning clamp. The drive bolt is screwed onto the upper end face of the positioning clamp and inserted into the interior of the positioning clamp. A clamping plate is provided on the lower end face of the drive bolt. The clamping plate is positioned corresponding to the force-receiving plate.

[0012] As a further technical solution, the side wall of the positioning clamp is provided with a support frame, the upper end of the support frame is provided with a support column, the upper end face of the support column is provided with a safety rope hanging ring, and the inside of the safety rope hanging ring is provided with a safety rope hanging groove.

[0013] As a further technical solution, the rust prevention and protection component includes a protective cover, which is fastened to the positioning clamp. The upper end face of the positioning clamp is provided with a fastening groove, and the inside of the protective cover is provided with a fastening strip, which is embedded in the inside of the fastening groove.

[0014] As a further technical solution, the beam has an H-shaped cross-section, and the positioning clamp is mounted on the upper end face of the beam.

[0015] As a further technical solution, a reinforcing frame is provided on the lower end face of the support frame, the reinforcing frame is disposed between the support frame and the positioning clamp, a strengthening frame is provided on the lower end face of the reinforcing frame, the strengthening frame is disposed on the side wall of the positioning clamp, and the strengthening frame is fixedly connected to the bottom surface of the reinforcing frame.

[0016] As a further technical solution, a reinforcing block is provided inside the safety rope hanging ring, and the safety rope hanging groove is opened on the inner side wall of the reinforcing block.

[0017] As a further technical solution, the side wall of the positioning clamp is provided with an insertion hole, an insertion block is inserted into the insertion hole, and a support block is provided on the side wall of the insertion block, and the support block is in contact with the beam.

[0018] As a further technical solution, the protective cover is fastened to the upper end face of the positioning clamp, and the protective cover and the positioning clamp are sealed and fitted together.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. In this disclosure, efficient installation is achieved through the modular design of the drive clamping assembly: the positioning clamp is directly clamped to the upper end face of the H-beam without the need for additional drilling or welding. The clamping plate and the force-bearing plate can be engaged to clamp the beam by simply turning the drive bolt. The clamping force can be precisely controlled with a torque wrench. Compared with traditional devices that require on-site measurement and welding, this method avoids the impact of high welding temperatures on the mechanical properties of the H-beam. When disassembling, the positioning clamp can be quickly removed by simply turning the bolt in the opposite direction. This solves the problem of traditional devices covering a large area and requiring disassembly at multiple points. A single person can complete the operation, which greatly reduces the risk of working at height.

[0021] 2. In this disclosure, the protective cover and positioning clamp are sealed by a snap-fit ​​design (the snap-fit ​​strip is embedded in the snap-fit ​​groove and filled with sealant) to form a fully enclosed protective structure, which can effectively block rainwater, moisture and corrosive gases, and the protection level reaches the IP65 standard, reducing the corrosion rate of core components (such as drive bolts and clamping discs) by more than 80%.

[0034] As shown in Figures 1-4, a safety rope attachment device based on an H-beam according to this disclosure is provided, comprising:

[0035] Beam 1, with positioning clamps 2 installed on beam 1;

[0036] Drive clamping assembly 3, which is mounted on positioning clamp 2;

[0037] Rust prevention and protection component 4 is disposed on the upper end face of positioning clamp 2;

[0038] The drive clamping assembly 3 includes a clamping groove 3-1, which is opened on the side wall of the positioning clamp 2. A force-bearing plate 3-2 is provided on the inner bottom surface of the clamping groove 3-1. The force-bearing plate 3-2 is in contact with the beam 1. A drive bolt 3-3 is provided on the upper end surface of the positioning clamp 2. The drive bolt 3-3 is screwed onto the upper end surface of the positioning clamp 2 and inserted into the interior of the positioning clamp 2. A clamping plate 3-4 is provided on the lower end surface of the drive bolt 3-3. The clamping plate 3-4 is positioned corresponding to the force-bearing plate 3-2.

[0039] The rust prevention and protection component 4 includes a protective cover 4-1, which is fastened to the positioning clamp 2. The upper end face of the positioning clamp 2 is provided with a fastening groove 4-2. The inside of the protective cover 4-1 is provided with a fastening strip 4-3, which is embedded in the inside of the fastening groove 4-2.

[0040] In some examples, first, the position of the beam 1 is determined, the clamping groove 3-1 of the driving clamping assembly 3 is opened on the side wall of the positioning clamp 2, and the force-bearing plate 3-2 is placed on the inner bottom surface of the clamping groove 3-1 so that it fits tightly against the beam 1. The function of the force-bearing plate 3-2 is to evenly distribute the clamping force and avoid causing local damage to the surface of the beam 1.

[0041] Tighten the drive bolt 3-3 on the upper end face of the positioning clamp 2. The drive bolt 3-3 should be slowly screwed in to ensure that it is accurately inserted into the positioning clamp 2. Install the clamping plate 3-4 on the lower end face of the drive bolt 3-3. Adjust the position of the clamping plate 3-4 so that it strictly corresponds to the position of the force-bearing plate 3-2. By tightening the drive bolt 3-3, the clamping plate 3-4 can be gradually moved closer to the force-bearing plate 3-2, thereby firmly clamping the beam 1 between the two. In actual operation, a torque wrench can be used to control the tightening force of the drive bolt 3-3 to ensure that the clamping force meets the design requirements and is uniform and stable.

[0042] The upper end face of the positioning clamp 2 is provided with a fastening groove 4-2. The protective cover 4-1 of the anti-rust protection component 4 is fastened onto the positioning clamp 2. The fastening strip 4-3 inside the protective cover 4-1 must be accurately embedded into the inside of the fastening groove 4-2 to achieve a tight fastening. In the construction of open-air bridge steel structures, in order to prevent rainwater, moisture and other factors from causing rust to the positioning clamp 2 and the drive clamping component 3, a corrosion-resistant material protective cover 4-1 is selected, and it is ensured that the protective cover 4-1 is sealed and fitted to the upper end face of the positioning clamp 2. During installation, an appropriate amount of sealant can be applied at the contact point between the fastening strip 4-3 and the fastening groove 4-2 to further enhance the sealing effect and prevent moisture from entering.

[0043] As shown in Figures 1 to 4, this embodiment proposes that the side wall of the positioning clamp 2 is provided with a support frame 3-5, the upper end of the support frame 3-5 is provided with a support column 3-6, the upper end face of the support column 3-6 is provided with a safety rope hanging ring 3-7, and the inside of the safety rope hanging ring 3-7 is provided with a safety rope hanging groove 3-8.

[0044] In some examples, a support frame 3-5 is installed on the side wall of the positioning clamp 2. The installation angle and position of the support frame 3-5 should ensure that the support column 3-6 at its upper end can be vertically upward. A safety rope hanging ring 3-7 is installed on the upper end face of the support column 3-6. The safety rope hanging groove 3-8 inside the safety rope hanging ring 3-7 is used to hang the safety rope. The construction worker accurately hangs the hook of his own safety rope into the safety rope hanging groove 3-8.

[0045] For example, as shown in Figure 1, the cross-section of beam 1 is H-shaped, and positioning clamp 2 is clamped on the upper end face of beam 1.

[0046] In some examples, since the cross-section of beam 1 is H-shaped, the positioning clip 2 is accurately clamped on the upper end face of beam 1. The installation position of the positioning clip 2 needs to be determined according to the actual needs of the safety rope in the construction to ensure that the subsequent attachment of the safety rope can meet the activity range and safety requirements of the construction personnel.

[0047] For example, as shown in Figure 2, a reinforcing frame 5 is provided on the lower end face of the support frame 3-5. The reinforcing frame 5 is located between the support frame 3-5 and the positioning clamp 2. A reinforcement frame 6 is provided on the lower end face of the reinforcing frame 5. The reinforcement frame 6 is located on the side wall of the positioning clamp 2. The reinforcement frame 6 is fixedly connected to the bottom surface of the reinforcing frame 5.

[0048] In some examples, to enhance the stability of the support frame 3-5, a reinforcing frame 5 is installed on the lower end face of the support frame 3-5. The reinforcing frame 5 is positioned between the support frame 3-5 and the positioning clamp 2, serving to reinforce the support. A further reinforcing frame 6 is installed on the lower end face of the reinforcing frame 5. The reinforcing frame 6 is fixed to the side wall of the positioning clamp 2 and is firmly connected to the bottom surface of the reinforcing frame 5, further improving the stability of the entire support structure.

[0049] For example, as shown in Figure 1, a reinforcing block 7 is provided inside the safety rope hanging loop 3-7, and the safety rope hanging groove 3-8 is opened on the inner side wall of the reinforcing block 7.

[0050] In some examples, a reinforcing block 7 is installed inside the safety rope loop 3-7, and a safety rope groove 3-8 is formed on the inner side wall of the reinforcing block 7. The reinforcing block 7 can enhance the strength of the safety rope loop 3-7 and prevent deformation or damage due to long-term hanging of the safety rope or bearing large tension.

[0051] For example, as shown in Figure 4, the side wall of the positioning clamp 2 has an insertion hole 8, and an insertion block 9 is inserted into the insertion hole 8. The side wall of the insertion block 9 is provided with a support block 10, and the support block 10 is in contact with the beam 1.

[0052] In some examples, an insertion hole 8 is opened on the side wall of the positioning clamp 2. The insertion block 9 is inserted into the insertion hole 8. The side wall of the insertion block 9 is equipped with a support block 10. The position of the support block 10 is adjusted so that it fits tightly with the beam 1. The support block 10 plays the role of auxiliary support and enhancing the stability of the connection between the positioning clamp 2 and the beam 1.

[0053] For example, as shown in Figure 2, the upper end face of the protective cover 4-1 is fastened to the positioning clamp 2, and the protective cover 4-1 and the positioning clamp 2 are sealed and fitted together.

[0054] In use, the clamping force generation mechanism drives the bolt 3-3 to be screwed into the upper end face of the positioning clamp 2 through the thread. The clamping plate 3-4 at its lower end and the force-receiving plate 3-2 in the clamping groove 3-1 form a clamping structure. When the driving bolt 3-3 is screwed, the axial force of the bolt is transmitted to the upper flange surface of the H-shaped steel beam through the clamping plate 3-4. At the same time, the force-receiving plate 3-2 acts as a reaction force support surface and presses against the lower surface of the beam 1, forming bidirectional compressive stress.

[0055] Align the positioning clamp 2 with the upper flange of the H-beam, ensuring the force-bearing plate 3-2 in the clamping groove 3-1 fits against the lower surface of the beam 1. Initially align the upper end face of the positioning clamp 2 with the top surface of the upper flange of the beam 1. Insert the insertion block 9 horizontally through the insertion hole 8 on the side wall of the positioning clamp 2 until the support block 10 is tightly fitted against the outer side of the web of the beam 1, forming a three-point positioning (upper flange clamping point + abutment points of the two support blocks 10). Temporarily fix the position of the positioning clamp 2. Screw the drive bolt 3-3 into the threaded hole on the upper end face of the positioning clamp 2, ensuring the bolt axis is perpendicular to the surface of the beam 1. Align the lower clamping plate 3-4 with the center of the force-bearing plate 3-2. Fix the support frame 3-5 to the pre-set mounting hole on the side wall of the positioning clamp 2 using bolts. Adjust the angle of the support frame 3-5 until the support column 3-6 is vertically upward. Weld or bolt one end of the reinforcing frame 5 to the lower end of the support frame 3-5, and fix the other end to the side wall of the positioning clamp 2 using the reinforcing frame 6, forming a 4-point positioning clamp. A 5° triangular support structure ensures that all nodes are firmly connected without wobbling. The safety rope loop 3-7 is welded or bolted to the top of the support column 3-6. Silicone sealant is evenly applied to the edge of the fastening groove 4-2 on the upper surface of the positioning clamp 2. The construction worker wears a safety belt, aligns the hook at the end of the safety rope with the groove, and fastens it vertically downwards, ensuring that the hook is fully engaged at the bottom of the groove. During operation, the construction worker must keep the safety rope in a slack state to avoid excessive stretching; during movement, it should be moved slowly to reduce the additional load caused by the swing of the safety rope.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
