Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a hanging structure for a safety belt in high-altitude edge operation. Background Technique

[0002] With the development of building engineering technology, during the construction of high-rise and super-high-rise residential buildings, operators often need to perform high-altitude edge operations at overhanging parts such as balconies and bay windows, such as external wall masonry, external thermal insulation construction of balcony parts, railing installation, garbage cleaning, etc. When there is a situation where the external scaffold has been removed during the construction of some sub-projects, ensuring the safety of operators in high-altitude edge operations is the key and difficult point of project construction. At present, the most common installation method of a safety belt is to fixedly install a hanging plate on a structural member through expansion bolts, and then hook the buckle of the safety belt on the hanging plate; however, in the actual application process, due to the frequent high-altitude edge operations and the relatively wide operation surface during the main structure construction of building engineering, hanging plates need to be set at multiple places. When fixedly installing the hanging plate, holes need to be drilled on the structural member, and after the hanging plate is used, the expansion bolts need to be cut. The installation and removal process of the hanging plate is time-consuming and laborious. Moreover, once any one of the expansion bolts loosens, accidents such as high-altitude falls of operators in high-altitude edge operations will occur, and the safety performance is poor. Therefore, a hanging structure for a safety belt in high-altitude edge operation should be provided. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a hanging structure for a safety belt in high-altitude edge operation aiming at the deficiencies in the above-mentioned existing technology. The structure is simple and reasonably designed. By installing a connecting screw through a reserved hole at a suitable height position, it is not necessary to drill expansion bolt installation holes on the structural shear wall. When an operator performs a high-altitude edge operation on an outdoor balcony structural slab, hook the buckle of the safety belt on the fixing ring. The connecting screw, steel backing plate and locking nut are reliably connected, not easy to fall off from the structural shear wall, and the on-site installation and disassembly are very convenient, time-saving and labor-saving, and can improve the construction safety of operators in high-altitude edge operations.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a hanging structure for a safety belt in high-altitude edge operation, characterized in that it includes a connecting screw passing through and matching with a reserved hole, a steel backing plate and a locking nut sleeved on the connecting screw. One end of the connecting screw is provided with a fixing ring, the fixing ring is located outside the structural shear wall, and both the steel backing plate and the locking nut are located inside the structural shear wall. The buckle of the safety belt is hooked on the fixing ring.

[0005] For the above-mentioned edge high-altitude operation safety belt hanging structure, it is characterized in that: a spring washer is installed between the lock nut and the steel backing plate.

[0006] For the above-mentioned edge high-altitude operation safety belt hanging structure, it is characterized in that: the length and width of the steel backing plate are not less than 70 mm, and the thickness of the steel backing plate is not less than 10 mm.

[0007] For the above-mentioned edge high-altitude operation safety belt hanging structure, it is characterized in that: the inner diameter of the fixed ring ranges from 50 mm to 70 mm.

[0008] The utility model has the following advantages compared with the prior art:

[0009] 1. By setting a connecting screw rod for passing through a reserved hole, a fixed ring is arranged at one end of the connecting screw rod, and a steel backing plate and a lock nut are installed at the other end of the connecting screw rod. In actual use, the fixed ring is located on the outer side of the structural shear wall, and the steel backing plate and the lock nut are both located on the inner side of the structural shear wall. When the operator conducts edge high-altitude operation on the outdoor balcony structural slab, the buckle of the safety belt is hooked on the fixed ring. The connecting screw rod, the steel backing plate and the lock nut are reliably connected and are not easy to fall off from the structural shear wall, and the on-site installation and disassembly are very convenient, which can improve the construction safety of the operator in edge high-altitude operation.

[0010] 2. The number of reserved holes on the structural shear wall of the utility model is multiple, and the multiple reserved holes are arranged at equal intervals. Reserved holes are also arranged on the outdoor balcony structural slab. In actual use, the connecting screw rod can be installed in a reserved hole at a suitable height position. It is not necessary to drill expansion bolt installation holes on the structural shear wall, but the connecting screw rod is fixedly installed by using the reserved holes, and the hanging structure is convenient for disassembly and assembly and can be recycled and reused.

[0011] 3. The utility model has a simple structure, reasonable design, low manufacturing cost and is convenient for popularization and application.

[0012] In summary, the utility model has a simple structure and reasonable design. By installing the connecting screw rod in a reserved hole at a suitable height position, it is not necessary to drill expansion bolt installation holes on the structural shear wall. When the operator conducts edge high-altitude operation on the outdoor balcony structural slab, the buckle of the safety belt is hooked on the fixed ring.

During actual use, when the operator performs edge high-altitude operations on the outdoor balcony structural slab 2, since the height of the outdoor balcony protective wall 3 is low, it cannot play a protective role at all, nor can it play a role in hanging the safety belt 8. Therefore, the safety belt 8 can only be hung on the structural shear wall 1 or the outdoor balcony structural slab 2 on the upper layer. When this hanging structure is installed in any one of the reserved holes 4 on the structural shear wall 1 or the outdoor balcony structural slab 2 on the upper layer, the fixed ring 5-2 is located outside the structural shear wall 1, and both the steel backing plate 6 and the locking nut 7 are located inside the structural shear wall 1.

[0023] In this embodiment, the number of reserved holes 4 on the structural shear wall 1 is multiple, and the multiple reserved holes 4 are arranged at equal intervals. Reserved holes 4 are also provided on the outdoor balcony structural slab 2. During actual use, the reserved holes 4 at an appropriate height position can be selected for the installation of the connecting screw 5-1. Instead of drilling expansion bolt installation holes on the structural shear wall 1, the reserved holes 4 are used for the fixed installation of the connecting screw 5-1.

[0024] In this embodiment, a spring washer is installed between the lock nut 7 and the steel backing plate 6.

[0025] In this embodiment, the connecting screw 5-1 includes a connecting rod section and a threaded rod section arranged coaxially. The fixing ring 5-2 is provided at one end of the connecting rod section. The length of the exposed end of the threaded rod section passing through the reserved hole 4 is not less than 50 mm.

[0026] In this embodiment, both the length and the width of the steel backing plate 6 are not less than 70 mm, and the thickness of the steel backing plate 6 is not less than 10 mm.

[0027] In this embodiment, the inner diameter of the fixing ring 5-2 ranges from 50 mm to 70 mm.

[0028] As Figure 1 and Figure 2 shown, during actual use, when the operator performs edge high-altitude operations on the outdoor balcony structural slab 2, first select the reserved holes 4 at an appropriate height on the structural shear wall 1 for the installation of the connecting screw 5-1. Insert the connecting screw 5-1 from the outside of the structural shear wall 1 to the inside of the structural shear wall 1, so that the fixing ring 5-2 is located on the outside of the structural shear wall 1. Then, sleeve the steel backing plate 6 and the lock nut 7 on the threaded rod section of the connecting screw 5-1 to achieve reliable connection of the connecting screw 5-1 on the structural shear wall 1. Finally, sleeve the buckle 8-1 of the safety belt 8 on the fixing ring 5-2, and then the edge high-altitude operation can be carried out, which improves the safety of the operator's edge high-altitude operation. The connecting screw 5-1 is convenient to disassemble and assemble, time-saving and labor-saving, can be recycled and reused, and is convenient for popularization and application.
