Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a safety protection net for high-altitude operations on exterior walls. Background Technology

[0002] Safety netting for high-altitude construction work is a protective device specifically designed for high-altitude construction, primarily used to prevent personnel, tools, or materials from falling, ensuring construction safety and protecting the surrounding environment. It is typically woven from high-strength polyethylene or nylon rope, possessing properties such as wear resistance, UV resistance, and corrosion resistance. The mesh density meets national standards (e.g., GB5725-2017), effectively intercepting falling objects. The safety netting is divided into vertical netting (suspended vertically on the outside of the scaffolding) and horizontal netting (stretched horizontally below the working level), with metal buckles and ropes along the edges, securely fixed by steel supports or anchors.

[0003] For example, authorization announcement number CN222894025U discloses an automatic deployment device for safety nets used in high-altitude operations on building facades. This device includes a fixed frame and a safety net. Support rods are symmetrically fixed on the fixed frame, and adjusting frames are fitted onto the support rods. Hydraulic diagonal braces are symmetrically hinged to the bottom of the adjusting frames, with the other end of each hydraulic diagonal brace hinged to the fixed frame. Electric push rods are provided on both sides of the adjusting frame, and clamping components are arrayed on both the support rods and the inner side of the adjusting frame. These clamping components are fixedly connected to both sides of the safety net. The beneficial effects of this invention are: the safety net can be extended and retracted by the electric push rods via a remote control device, allowing adjustment of the net's extension range according to different usage needs; the angle between the fixed frame and the support rods can be adjusted by the hydraulic diagonal braces, which can buffer the potential energy of accidental falls or promptly intercept falling objects, ensuring the safety of falling personnel, surrounding people, and the environment.

[0004] However, in the above-mentioned technologies, the entire protective netting device is fixed to the exterior wall of the building by a fixing frame. After the exterior wall construction is completed, personnel need to disassemble the entire protective netting device from the outside of the exterior wall, which is quite troublesome and dangerous. Therefore, the market urgently needs to develop a safety netting device for high-altitude operations on exterior walls to help people solve the existing problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a safety net for high-altitude operations on exterior walls, comprising a fixing plate 1 and a floor slab 2. Two fixing plates 1 are arranged parallel to each other on the upper end of the floor slab 2. The two fixing plates 1 are fixedly connected to the upper end face of the floor slab 2 by multiple first bolts 201. A vertical support plate 101 is fixedly connected to the middle of the upper end of the fixing plate 1. A first limiting tube 102 is fixedly connected to the rear end of the upper end of the vertical support plate 101. A second limiting tube 103 is fixedly connected to the front end of the upper end of the vertical support plate 101. A main support rod 3 is provided inside the first limiting tube 102 and the second limiting tube 103. The rear end of the main support rod 3 extends out of the rear end of the first limiting tube 102 and is fixedly connected to a limiting column head 301. The front end of the main support rod 3 extends out of the front end of the second limiting tube 103 and is fixedly connected to a C-shaped connector 302, so that the main support rod 3 can extend and retract longitudinally at the upper end of the vertical support plate 101. A first horizontal support rod 4 is connected between the C-shaped connectors 302 at the front end of the support rod 3. A connecting column 104 is fixedly connected to the middle of the inner end face of the two vertical support plates 101. A second horizontal support rod 5 is connected between the two connecting columns 104. A protective net 6 is fixedly connected between the first horizontal support rod 4 and the second horizontal support rod 5. After the fixing plate 1 is fixed to the floor slab 2, the two main support rods 3 extend forward synchronously, so that the front ends of the two main support rods 3 drive the first horizontal support rod 4 to extend into the floor. When the first horizontal support rod 4 extends, the protective net 6 between the first horizontal support rod 4 and the second horizontal support rod 5 is simultaneously unfolded to protect the lower end of the high-altitude workers. When the main support rod 3 extends, it is guided by the first limiting tube 102 and the second limiting tube 103. At the same time, the rear end of the main support rod 3 is limited by the limiting column head 301 to prevent it from detaching from the first limiting tube 102.

[0024] Please see Figure 2 , Figure 3 and Figure 4When disassembling, by simultaneously pulling the two main support rods 3 back to the upper end of the floor slab 2, the center of gravity of the entire protective net device is placed on the floor slab 2. Then, by removing multiple first bolts 201, the fixing plate 1 and the floor slab 2 can be separated. The entire device can then be pulled back towards the floor slab 2. Rectangular connectors 401 are fixedly connected to both sides of the first transverse support rod 4. The two rectangular connectors 401 are respectively inserted into the two C-shaped connectors 302 and fixedly connected to the C-shaped connectors 302 by second bolts 402. By removing the second bolts 402, the first transverse support rod 4 can be separated from the two main support rods 3. Each connecting post 104 has a limiting plate 105 fixedly connected to one end of each adjacent end. An internally threaded connecting tube 106 is rotatably connected to the outside of the limiting plate 105. Externally threaded parts 501 are fixedly connected to both sides of the outer wall of the second transverse support rod 5. The two ends of the second transverse support rod 5 are respectively inserted into the two internally threaded connecting tubes 106 and the externally threaded parts 501 are threadedly connected to the internally threaded connecting tubes 106. By rotating the two internally threaded connecting tubes 106 to disengage from the two ends of the second transverse support rod 5, the protective net 6 can be rolled up by rotating the second transverse support rod 5 or the first transverse support rod 4, thereby disassembling the entire protective net device.

[0025] Working Principle: During use, the safety net for high-altitude operations on exterior walls is installed and positioned as a whole by fixing the fixing plate 1 to the floor slab 2 with bolts. During construction, the operator pushes the main support rods 3 on both sides forward along the first limiting tube 102 and the second limiting tube 103 from inside the building, driving the first horizontal support rod 4 to move horizontally outward, so that the safety net 6 automatically unfolds on the exterior facade of the building to form a fall protection barrier. The main support rod 3 is prevented from over-extending by the limiting column head 301, and the C-shaped connector 302 is bolted to the rectangular connector 401 to ensure structural stability. Disassembly is performed in reverse: first, retract the main support rod 3 to return the safety net 6 to the floor slab area, remove the first bolt 201, and then move the entire device back indoors. Then, by removing the second bolt 402, the first horizontal support rod 4 is separated from the two main support rods 3, and by rotating the internal threaded connecting tube 106, the second horizontal support rod 5 is separated from the two connecting columns 104. The safety net 6 can then be rolled up by rotating the second horizontal support rod 5 or the first horizontal support rod 4, completing the safe disassembly. The entire process requires no outdoor high-altitude work, effectively reducing the risk of dismantling.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
