Description

Technical Field

[0001] This utility model relates to the field of building construction safety technology, specifically to a protective device for high-rise wall construction. Background Technology

[0002] In high-rise building construction, insulation layer installation, and finishing removal or repair work, preventing workers from falling and the falling of building materials, tools, and other objects is a crucial safety measure. Traditional safety measures often involve erecting full-span scaffolding and hanging safety nets or dense mesh netting. However, this full-scaffolding approach requires a large amount of steel, occupies a large area of ​​land, and has a high construction cost that accounts for a significant portion of the total project cost. Furthermore, it necessitates the long-term closure of the surrounding area, severely impacting traffic and pedestrian access. Additionally, the integrated safety netting is inconvenient to install and dismantle, difficult to reuse, and economically inefficient. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a protective device for high-rise wall construction that is easy to install, has good protective effect and can be reused.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A protective device for high-rise wall construction includes a suspension mechanism installed on the roof of a building and a protective net installed on the outside of the building wall for shielding the building wall. The protective net includes several connecting pieces that are connected to each other in a vertical direction to form an integral structure. Multiple downward-extending traction ropes are fixed on the suspension mechanism, and each traction rope is connected to the protective net for supporting the protective net.

[0005] As an optimization, the lower end of the upper connecting piece overlaps the upper outer side of the lower connecting piece, and the overlapping positions of the two connecting pieces are connected together.

[0006] As an optimization, the two connecting pieces are clamped together at their overlapping positions using rope clamps.

[0007] As an optimization, the connecting piece includes a frame and a grid layer located within the frame. The grid layer is formed by interwoven steel wires, and the frame is used to support and define the external dimensions of the grid layer.

[0008] As an optimization, the lower end of the traction rope is tensioned by configuring a counterweight or by anchoring it to the bottom of the building.

[0009] As an optimization, the suspension mechanism includes multiple support frames for mounting on the building roof. A horizontally positioned support beam, with its front end extending beyond the building wall, is fixedly connected to each support frame. Each support beam is equipped with a corresponding lifting device, and each traction rope corresponds to a lifting device. A fixed pulley is installed at the front end of the support beam. The upper end of the traction rope passes over the fixed pulley and is wound within the lifting device. The lifting device can control the raising and lowering of the traction rope to achieve lifting and lowering adjustment.

[0010] As an optimization, a counterweight frame for placing on the building roof is provided below the rear end of the supporting beam, and the counterweight frame is detachably connected to the supporting beam through a connecting frame.

[0011] Compared with existing technologies, the protective netting in this invention is quickly assembled from several standardized connecting pieces using rope clamps, resulting in high installation and disassembly efficiency, significantly shortening the construction cycle. It is also reusable, offering good economic benefits. The protective netting uses a steel wire mesh layer, which has high strength and can effectively intercept medium to large falling objects generated during construction. The entire structure is tensioned by traction ropes to form a stable, rigid protective surface. The suspension mechanism is stabilized by counterweights, and the lower end of the traction rope is tensioned, resulting in a strong wind load resistance and high safety. Attached Figure Description

[0015] like Figure 1 As shown in this specific embodiment, the protective device for high-rise wall construction includes a suspension mechanism installed on the building roof and a protective net installed on the outside of the building wall for shielding the wall surface. The protective net includes several connecting pieces 1, which are vertically connected to each other to form an integral structure. Multiple downward-extending traction ropes 2 are fixed to the suspension mechanism, each traction rope 2 connected to the protective net for tensioning. In practice, depending on the width of the building wall and the actual lateral length of the connecting pieces, multiple connecting pieces can be horizontally spliced ​​to ensure coverage of the entire building wall. The traction rope is a helical bundle of steel wires twisted together according to certain rules, meeting mechanical performance and geometric dimensions requirements. The wire rope consists of steel wires and a core. The wire rope is first made by twisting multiple layers of steel wires into strands, and then, with the core as the center, a certain number of strands are twisted into a helical rope.

[0016] In this specific embodiment, the lower end of the upper connecting piece 1 is attached to the outer side of the upper end of the lower connecting piece 1, and the two connecting pieces 1 are connected to each other at their attachment positions.

[0017] In this specific embodiment, the two connecting pieces 1 are clamped together at their overlapping positions using rope clamps. The spacing between the rope clamps is calculated based on the actual site conditions, and the clamps meet national standards to ensure long-term reliability. The overlapping area of ​​the two connecting pieces is seamlessly covered, preventing objects from falling or penetrating. Furthermore, the connecting pieces can also be clamped and fixed to the traction rope using rope clamps, with the tightening torque meeting the technical requirements for preventing slippage.

[0018] In this specific embodiment, the connecting piece 1 includes a frame and a mesh layer located within the frame. The mesh layer is formed by interwoven steel wires, and the frame supports and defines the external dimensions of the mesh layer. The mesh layer is woven from high-strength steel wires into a mesh structure, with the wire diameter and mesh size determined by actual conditions. The wire mesh is a mesh material made of low-carbon steel, medium-carbon steel, high-carbon steel, or stainless steel through weaving and welding processes. Production processes include ordinary weaving, embossed weaving, and spot welding. Its specifications comply with relevant standards, and attention must be paid to the matching of wire diameter and mesh size. The galvanizing process often uses hot-dip galvanizing to enhance corrosion resistance.

[0019] In this specific embodiment, the lower end of the traction rope 2 is fixed to the bottom of the building by means of a counterweight or an anchor for tensioning.

[0020] In this specific embodiment, the suspension mechanism includes multiple support frames 3 for mounting on the building roof. Horizontally arranged support beams 4, with their front ends extending beyond the building wall, are fixedly connected to the support frames 3. Each support beam 4 is equipped with a corresponding lifting device, and each traction rope 2 corresponds to one lifting device. A fixed pulley is installed at the front end of each support beam 4. The upper end of the traction rope 2 passes over the fixed pulley and is wound within the lifting device. The lifting device can control the raising and lowering of the traction rope 2 to achieve height adjustment. After the entire protective netting is installed, a safety lock can be used to lock the traction rope, which not only improves safety but also extends the service life of the lifting device.

[0021] In this specific embodiment, a counterweight frame 5 for placing on the roof of the building is provided below the rear end of the supporting beam 4. The counterweight frame 5 and the supporting beam 4 are detachably connected together by a connecting frame 6.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail can be made without departing from the spirit and scope of this utility model as defined in the appended claims.
