Description

Technical Field

[0001] The utility model relates to the technical field of safety nets, in particular to a novel scaffolding safety net. Background Art

[0002] After the scaffolding is erected, a safety net is usually hung for protection. The safety net is tied to the scaffolding poles or crossbars with nylon ropes or self-locking tie straps.

[0003] After searching, the application with patent number CN202123119641.3 discloses a horizontal safety net for cantilever scaffolding, including a net frame, the inner cavity of which is installed with a steel net, the left and right ends of which are connected to the inner wall of the net frame through elastic bands, the left end of which is hinged with a mounting plate, and the two side walls of the mounting plate are hinged with support rods;

[0004] Although the horizontal safety net for the cantilever scaffolding can stretch the spring through the first limit slider and the reaction force of the spring can effectively alleviate the impact force, thus achieving a buffering effect and avoiding damage caused by rigid contact, the horizontal safety net for the cantilever scaffolding fixes the safety net on the scaffolding through the mounting holes on the mounting plate, and its stability is poor. When the force on the side of the safety net away from the mounting plate is greater, the safety net is likely to tilt, posing a safety hazard.

[0005] Therefore, we proposed a new type of scaffolding safety net. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a new scaffolding safety net, which solves the problem that the existing device fixes the safety net on the scaffolding through the mounting holes on the mounting plate, but its stability is poor. When the force on the side of the safety net away from the mounting plate is greater, it is easy to cause the safety net to tilt, posing a safety hazard.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a new type of scaffolding safety net, including a mounting frame, a safety net is arranged inside the mounting frame, and limiting grooves with semicircular cross-sections and fixing holes symmetrically distributed on both sides of the limiting grooves are symmetrically opened on both sides of the bottom surface of the mounting frame, and a locking assembly is arranged inside the fixing hole.

[0008] Preferably, the locking assembly includes a U-shaped rod movably mounted inside the fixing hole, both ends of the U-shaped rod are provided with external threads and movably mounted with limit plates, and the U-shaped rod thread is mounted with nuts matching the external threads, wherein when the limit groove is stuck on the steel pipe of the scaffolding, the U-shaped rod is passed through the fixing hole and the limit plates are fixed to the two ends of the U-shaped rod using nuts, so that the U-shaped rod and the limit plates can be used to fix the installation frame on the scaffolding, thereby avoiding the installation frame from detaching from the scaffolding.

[0009] Preferably, there are sixteen fixing holes in total, and the sixteen fixing holes are evenly distributed on both sides of the limiting groove, wherein the twelve fixing holes cooperate with the locking assembly to increase the stability of the locking assembly in fixing the installation frame on the scaffold.

[0010] Preferably, the side wall of the installation frame is penetrated with connection holes, and there are 24 connection holes in total, and the 24 connection holes are evenly distributed around the installation frame, wherein the upper safety net can be easily fixed to the installation frame through the connection holes.

[0011] Preferably, the safety net includes an upper safety net and a lower safety net, the upper safety net is a nylon safety net, and the lower safety net is a steel net, wherein double protection can be provided by the upper safety net and then the lower safety net, wherein the upper safety net is used to buffer the material, and the lower safety net is used to support the material, thereby preventing the material from being too heavy and crushing the upper safety net.

[0012] Preferably, the upper safety net is fixed to the installation frame through a self-locking cable tie power transmission connection hole, and the lower safety net is fixedly welded to the bottom surface of the installation frame. Since the upper safety net is made of nylon, it is easily damaged during use, and the self-locking cable tie is used to facilitate the installation and removal of the upper safety net.

[0013] The utility model provides a new type of scaffolding safety net, which has the following beneficial effects:

[0014] 1. The novel scaffolding safety net is formed by clamping the limiting groove on the bottom surface of the installation frame on the steel pipe of the scaffolding, then passing the two ends of the U-shaped rod through the fixing holes, then sleeve the limiting plates on the two ends of the U-shaped rod, and finally sleeve the two ends of the U-shaped rod through the nut thread, and then use the limiting plates and the U-shaped rod to fix the two sides of the installation frame on the steel pipe of the scaffolding, which is conducive to increasing the stability between the installation frame and the scaffolding steel pipe, and solves the problem that the existing device fixes the safety net on the scaffolding through the mounting holes on the mounting plate, which has poor stability. When the force on the side of the safety net away from the mounting plate is large, it is easy to cause the safety net to tilt, which has potential safety hazards;

[0015] 2. The new scaffolding safety net cushions the materials through the upper safety net, and then supports the materials on the top of the upper safety net through the lower safety net, so as to avoid the upper safety net from being broken and damaged due to large deformation caused by excessive weight of materials. The upper safety net is fixed to the installation frame through the connecting hole by a self-locking cable tie, which is convenient for removing the upper safety net for replacement, and is simple and convenient to use.
