Description

Technical Field

[0001] The invention belongs to the technical field of scaffold external hanging components, and in particular relates to a scaffold safety net installation fixture. Background Art

[0002] During the construction process, it is necessary to install a safety net on the side of the scaffolding away from the building wall. The safety net consists of a rectangular frame and a metal mesh welded inside the rectangular frame. It mainly has the functions of edge protection, dust isolation and noise reduction. It is an indispensable protective device in construction projects.

[0003] The safety net is generally connected to the vertical poles or cross beams of the scaffolding with ordinary bolts. Bolt holes need to be opened in the frames of two adjacent safety nets, and two bolt holes need to be opened at the same point of the vertical poles or cross beams of the scaffolding to fix the frames of two laterally adjacent or longitudinally adjacent safety net panels to the vertical poles or cross beams. Not only does it consume a large number of connecting bolts, but it also takes a long time to install and is inefficient.

[0004] In order to improve the installation efficiency, a connection assembly is generally used to connect the safety net and the scaffolding, such as the authorization announcement number CN 218234431 U discloses a disc-type scaffolding external safety net connection component. When using it, after assembling the disc-type scaffolding cross bar and the disc-type scaffolding column, the lowest layer of connecting and fixing pipes is fixed on the disc-type scaffolding cross bar by means of cross buckles, the angle between the rotating plate and the connecting and fixing pipe is kept at 180 degrees, the safety net frame is placed between the upper baffle plate and the connecting and fixing pipe, the moving pipe is moved so that the moving pipe and the upper baffle plate clamp the safety net frame, another connecting mechanism is used above the safety net frame, the rotating plate and the connecting and fixing pipe are at 90 degrees, the safety net frame is inserted between the L-shaped lower baffle plate and the connecting and fixing pipe, the connecting and fixing pipe is rotated to an angle of 180 degrees with the rotating plate, the connecting and fixing pipe is fixed on the disc-type scaffolding cross bar by means of cross buckles, the moving pipe is moved so that the moving pipe and the L-shaped lower baffle plate clamp the safety net frame, and the external hanging work of multiple safety net frames can be completed by repeating the steps.

[0005] During the construction process, especially for projects with a long construction span, the external safety nets often need to be temporarily partially dismantled to make holes or partially replaced. However, the above-mentioned connection assembly must move the moving tube away from the upper baffle and the lower baffle, so that the two safety nets (two adjacent safety nets fixed by the connection assembly) are changed from the clamped state to the unclamped state at the same time to complete the disassembly and assembly. The safety net in the unclamped state is easy to shake inside and outside, posing certain safety hazards. Therefore, when removing or replacing a safety net, the other adjacent safety net must be supported by a dedicated person to prevent it from falling and causing safety accidents. Summary of the invention

[0006] The purpose of the present invention is to provide a scaffolding safety net installation fixture, which can not only solve the problem of potential safety hazards in the safety net under temporary hole opening, replacement and other working conditions, but also improve the efficiency of disassembly and assembly of the safety net, thereby achieving the purpose of reducing costs and increasing efficiency.

[0009] When in use (taking two safety nets adjacent to each other as an example), the two safety nets adjacent to each other are installed by six clamps, two of which are located between the two adjacent safety nets, two of which are located at the upper end of the upper safety net, and two of which are located at the lower end of the lower safety net. Among them, the upper end frame of the upper safety net and the upper end frame of the lower safety net are both located in the first card slot of the clamp, and the lower end frame of the upper safety net and the lower end frame of the lower safety net are both located in the second card slot of the clamp. When the lower safety net needs to be disassembled, the baffle of the upper end clamp of the lower safety net is rotated so that the baffle is changed from vertical (perpendicular to the surface of the connecting plate) to horizontal (parallel to the surface of the connecting plate). At this time, the upper end of the lower safety net is freed from the baffle, so that the lower safety net can be separated from the first card slot limit, thereby realizing disassembly and assembly. During the disassembly and assembly process of the lower safety net, the lower end of the upper safety net is still firmly clamped in the second card slot, without the need for special personnel to support and fix it, thereby improving the safety and efficiency of disassembly and assembly of the safety net.

The safety net frame limiting cavity can ensure that the safety net frame is effectively fixed, so that the safety net can be hung in the first clamping slot.

[0012] In order to limit the position of the barrier rod and facilitate opening or locking of the barrier rod, the barrier rod rotating shaft is a barrier rod screw, and the barrier rod is connected to the barrier rod screw through a barrier rod nut.

[0017] When in use, the steel pipe of the scaffolding is located between the arc pressure plate and the connecting plate, the fastening screw is inserted into the fastening screw groove, the handle is pressed, and the eccentric wheel makes the arc pressure plate approach the connecting plate, so that the arc pressure plate and the connecting plate clamp the scaffolding steel pipe, thereby realizing the fastening installation of the clamp and the scaffolding steel pipe.

[0018] A gasket is sleeved on the fastening screw between the eccentric wheel and the arc-shaped pressure plate.

[0019] To ensure the tightness of the quick-release buckle, the fastening head is a nut. The position of the nut on the fastening screw can be adjusted by rotating the nut to adjust the distance between the fastening head and the eccentric wheel to ensure that after pressing the folding handle, the quick-release buckle as a whole is in the best fastening state.
