Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation technology, and in particular to a safety suspension device for the top edge of a structure. Background Technology

[0002] When carrying out various construction operations on the exterior of a building roof, whether it's suspending safety ropes on suspended platforms, having workers wear safety belts for high-altitude operations, or wearing safety belts for protection during tasks such as wall painting, a common problem is often encountered:

[0003] In some scenarios, safety belts lack safe and reliable dedicated suspension points. Due to the lack of standardized suspension positions, construction workers often have to temporarily hang the safety belts on existing building structures such as flues and pipes. This conventional practice is not only cumbersome and inconvenient, affecting construction efficiency, but also causes varying degrees of damage to the surface integrity and structural stability of structures such as flues during the suspension and dismantling process. This is not only detrimental to the protection of existing building facilities, but also poses certain safety hazards.

[0004] Meanwhile, in bridge construction scenarios, for example, when construction workers are working outside concrete guardrails, they also encounter the problem of safety ropes and safety belts not having reliable suspension measures, resulting in loopholes in construction safety protection and threatening the personal safety of workers at height.

[0023] Example

[0024] like Figure 1 - Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem of unreliable suspension technology in existing high-altitude operations. The overall idea is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a structural top edge safety suspension device, including a wall 11, with L-shaped steel plates 12 symmetrically arranged on the side wall of the wall 11, and suspension ear plates 13 and mating plates 14 respectively provided at the upper end of the L-shaped steel plates 12, and the suspension ear plates 13 and mating plates 14 are fastened together by a first bolt fastener 15.

[0026] The lower end of the L-shaped steel plate 12 is provided with an adjustable fastening structure;

[0027] The adjustable fastening structure includes an extended adjustment plate 16, which is fastened to each other by a second bolt fastener 17. A through groove 22 is provided inside the wall 11, and a portion of the second bolt fastener 17 is located inside the through groove 22.

[0028] Both L-shaped steel plates 12 and the extension adjustment plate 16 are steel plates with a thickness of not less than 10mm. Safety ropes and other hanging objects can be suspended through the suspension ear plate 13. This device is reusable. On structures with open edges, the length of the second bolt fastener 17 can be adjusted according to the structural thickness. When installing this device, the strength of the concrete structure must meet the design requirements. At the same time, this device has a wide range of applications. It can be used on structures with open edges, such as parapet walls on building roofs or guardrails in bridge projects. It has a simple structure, is easy to disassemble, and improves the stability and convenience of high-altitude operation suspension.

[0029] Using the L-shaped steel plate 12, suspension ear plate 13, mating plate 14, and first bolt fastener 15, the worker can fasten the suspension ear plate 13 and mating plate 14 with the first bolt fastener 15, thereby achieving a stable connection between the upper part of the device and the wall 11. The adjustable fastening structure provided at the lower end of the L-shaped steel plate 12 provides an adjustable fastening method for the connection between the lower part of the device and the wall 11, thereby enabling adaptive adjustments during device installation.

[0030] The L-shaped steel plate 12 has symmetrically convex grooves 18 inside. The upper end of the extension adjustment plate 16 is symmetrically fixed with sliders 19. The sliders 19 are located inside the convex grooves 18 and are slidably installed with the convex grooves 18. Rotary screws 21 are symmetrically provided between the L-shaped steel plate 12 and the extension adjustment plate 16. The rotating screws 21 are threadedly installed with the L-shaped steel plate 12 and are rotatably installed with the extension adjustment plate 16.

[0031] By using the extension adjustment plate 16, the second bolt fastener 17, and the through slot 22, the workers adjust the relative length of the L-shaped steel plate 12 and the extension adjustment plate 16, drill holes in the wall 11, and fasten the extension adjustment plate 16 by passing the second bolt fastener 17 through the through slot 22, thereby achieving stable fixation of the lower part of the device to the wall 11 at different positions.

[0032] The first bolt fastener 15 and the second bolt fastener 17 can be selected in any length or strength according to actual needs.

[0033] Through the convex groove 18, the slider 19 and the rotating screw 21, the operator rotates the rotating screw 21 to make it threadedly drive the slider 19 on the extension adjustment plate 16 to slide inside the convex groove 18 and achieve limit, causing the extension adjustment plate 16 to move downwards towards the L-shaped steel plate 12, thereby achieving precise adjustment and stable movement of the extension adjustment plate 16.

[0034] Working principle: In use, the operator first adjusts the relative length of the L-shaped steel plate 12 and the extension adjustment plate 16, then rotates the rotating screw 21 to make it threaded with the L-shaped steel plate 12, thereby driving the slider 19 on the extension adjustment plate 16 to slide inside the convex groove 18, and at the same time achieving the limit, causing the extension adjustment plate 16 to move downwards from the L-shaped steel plate 12; then, the operator drills a hole in the wall 11 with a drill bit, and fastens the extension adjustment plate 16 by passing the second bolt fastener 17 through the through groove 22, and then fastens the suspension ear plate 13 and the mating plate 14 by the first bolt fastener 15, finally completing the clamping.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation.
