Description

Technical Field

[0001] The utility model relates to the technical field of construction safety protection, in particular to a safety protection component used for the gap between an external scaffolding and an external wall. Background Art

[0002] Nowadays, the height of construction projects is getting higher and higher. During the construction of high-rise buildings, falling from height and falling objects from height have always been the two major high-risk hazards on the construction site. Figure 1 As shown, in particular, the gap between the external scaffolding 2 and the external wall 3 is actually the gap between the steel mesh 26 and the external wall 3. If the gap is too small, the external wall construction cannot be carried out, and if the gap is too large, the risk factor increases accordingly.

[0003] To effectively control these risks, two protective measures are currently in use. The most common is the use of a protective net, which is hung between the scaffolding and the exterior wall. This net is nailed to the exterior wall, with one side of the net hanging from a nail on the exterior wall and the other side hanging from the exterior scaffolding. This method is not only prone to loosening and thus fails to provide true protection, but the nail holes also affect the quality of exterior wall repairs. After the exterior wall paint application is completed, the exterior scaffolding needs to be removed. Performing exterior wall paint repairs before the scaffolding is removed presents a greater safety hazard.

[0004] Another protective measure is to use a hard cantilever protective layer. Although it can play a protective role, it may cause material transmission interference. At the same time, it is costly, inconvenient to assemble and disassemble, and is mostly used in places where people gather. It is not suitable for the safety protection of external scaffolding.

[0005] Therefore, it is necessary to design a protective component to solve the quality problems such as the inability to conveniently and reliably protect the gap between the external scaffolding and the exterior wall at the construction site, as well as the inconvenience of later dismantling, difficulty in repair, and poor appearance.

[0006] It should be noted that the above technical information is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or suggestion in any form that the above technical information constitutes prior art already known to those skilled in the art. Utility Model Content

[0007] In response to the deficiencies in the above-mentioned background technology, the present invention proposes a safety protection component for the gap between the external scaffolding and the external wall, which solves the technical problems such as the inability to conveniently and reliably protect the gap between the external scaffolding and the external wall, as well as the inconvenience of later dismantling, difficulty in repair, and poor appearance.

[0008] The technical solution of this application is:

[0009] A safety protection assembly for the gap between an exterior scaffold and an exterior wall comprises at least two retractable supports, one end of each retractable support connected to the exterior scaffold and the other end facing the exterior wall. A safety net is connected between adjacent retractable supports. The safety protection assembly provided by this technical solution is not only simple in structure, easy to assemble and disassemble, and highly versatile, making it easy to use and recycle. The safety net can be installed and fixed in the gap between the exterior scaffold and the exterior wall at any stage of construction. This not only solves safety issues but also has a wide range of applications. The retractable supports can be used to protect various gaps, making it suitable for different levels of the same exterior scaffold, different exterior scaffolds, and different construction projects. Furthermore, the safety net is directly connected to the exterior scaffold via the retractable supports without affecting the exterior wall, thus preventing damage to the exterior wall and eliminating the need to repair the exterior wall after the exterior scaffold is removed. Furthermore, during the later dismantling of the exterior scaffold, the safety net can be conveniently removed layer by layer as the exterior scaffold steel pipes are removed.

[0010] In addition to the above technical solution, as a preferred technical solution, the retractable support member is removably connected to the outer scaffold via scaffold-specific fasteners. This technical solution further enhances the versatility of the safety protection assembly by directly utilizing the outer scaffold's matching fasteners. This implicitly discloses that the retractable support member includes a pipe of the same thickness as the outer scaffold's steel pipe, facilitating direct fastening with the fasteners. Therefore, whether rotating the retractable support member between different locations on the same outer scaffold or between different construction projects, the safety protection assembly can be conveniently assembled and disassembled.

[0011] Based on the above technical solution, as a preferred technical solution, the fasteners are butt fasteners, and the retractable support member is detachably connected to the horizontal transverse steel tube of the external scaffold via the butt fasteners. This technical solution provides a further preferred technical solution, using butt fasteners to directly coaxially connect the retractable support member to the horizontal transverse steel tube. This can extend the overall length of the horizontal transverse steel tube by leveraging the length of the horizontal transverse steel tube itself, thereby shortening the size of the retractable support member, making it further miniaturized and improving the convenience of assembly, disassembly, and turnover.

[0012] As another preferred technical solution, the fasteners are vertical fasteners, and the retractable supports are detachably connected to the horizontal longitudinal steel tubes of the exterior scaffolding via the vertical fasteners. This technical solution provides another further preferred technical solution. Compared to using butt fasteners, this technical solution cannot further reduce the length of the retractable supports, but it provides more installation options. The retractable supports can be installed at any horizontal position along the exterior wall, and the spacing between adjacent retractable supports can be freely selected without being restricted by horizontal transverse steel tubes.

[0013] As another preferred technical solution, the fasteners are vertical fasteners, and the retractable supports are detachably connected to the vertical steel pipes of the exterior scaffolding via the vertical fasteners. This technical solution provides another further preferred technical solution. Compared to using butt fasteners, this technical solution cannot further reduce the length of the retractable supports, but it provides more installation options. The retractable supports can be installed at any height along the exterior wall, and the spacing between adjacent retractable supports can be freely selected without being restricted by horizontal transverse steel pipes and horizontal longitudinal cross pipes.

[0014] Based on the above technical solution, as a preferred technical solution, the retractable support comprises a fixed tube connected to the external scaffolding, with a movable tube inserted into the fixed tube. This technical solution provides a further preferred technical solution, configuring the retractable support as a double-tube nested structure. This not only simplifies the structure and facilitates fabrication, but also facilitates assembly and disassembly, and turnover. The length can also be easily adjusted by simply pulling the movable tube to change the length of the extension from the fixed tube. Furthermore, setting the length of the movable tube longer than the distance between the exterior wall and the fixed tube prevents the movable tube from falling in unexpected situations.

[0015] Based on the above technical solution, as a preferred technical solution, a first hook for connecting to the safety anti-fall net is provided at the end of the movable tube facing away from the outer scaffolding, and a second hook for connecting to the safety anti-fall net is provided on the outer scaffolding. This technical solution provides a further preferred technical solution. The provision of the first hook and the second hook not only improves the convenience of disassembly and assembly of the safety anti-fall net, but also improves reliability by being arranged on the retractable support and the outer scaffolding respectively. At the same time, the placement of the second hook can be flexibly adjusted according to site needs, thereby providing a variety of fixed position options for one side of the safety anti-fall net.

[0016] As another preferred technical solution, a first hook for connecting to the safety net is provided on the end of the movable tube facing away from the outer scaffold, and a second hook for connecting to the safety net is provided on the fixed tube. This technical solution provides another preferred technical solution, in which the positions of the first and second hooks are changed, and the safety net is directly arranged on the retractable support, allowing the safety net and the retractable support to be installed and removed simultaneously.

[0017] Based on the above technical solution, as a preferred technical solution, the first hook is fixedly connected to the movable tube, and the second hook is detachably connected to the external scaffold or the fixed tube. This technical solution provides a further preferred technical solution. The fixed first hook ensures reliability and improves integrity, while the detachable second hook improves flexibility.

[0018] On the basis of the above technical solution, as a preferred technical solution, the second hook is fixedly arranged on a clamp, and the clamp is connected to the external scaffolding or the fixed pipe.

[0019] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0020] The present utility model provides a safety protection component for the gap between the external scaffolding and the external wall. The safety anti-fall net can be installed and fixed in the gap between the external scaffolding and the external wall at any stage of construction. It not only solves the safety problem, but also has a wide range of applications. Through the retractable support members, it can be applied to the safety protection of various gaps. At the same time, the connection method of the safety anti-fall net avoids damage to the external wall, and there is no need to repair the external wall after the external frame is removed. In addition, in the process of dismantling the external scaffolding at a later stage, the safety anti-fall net can be conveniently removed layer by layer simultaneously as the scaffolding steel pipes are removed. The safety protection component provided by the present utility model can be mass-produced and installed in the factory, and only needs to be assembled and installed on site, which greatly improves construction efficiency and economic benefits.
