JP3056176U - Scaffolding safety net fittings - Google Patents

Abstract

(57) [Summary] [PROBLEMS] The present invention relates to a safety fitting which saves labor and time for setting up a safety net on a scaffold pipe, and is safe. A hook (3) is inserted into a net hook hole (8) at a joint of a safety net (9), an arm (4) is attached to a scaffold pipe (7), and a coil pulling spring (1).
The ball chain (2) with the mark is wound and hooked on the chain stopper cut (5).

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a device for easily attaching and detaching when constructing a scaffold at a construction site, setting up a safety net, and dismantling.

[0002]

[Prior art]

 Conventionally, the work of installing a safety net on a scaffold has used a string or a binding wire (thin wire). Strings were pierced one by one through holes in the net, wrapped around scaffolding pipes and tied with tools. Also, the work to disassemble the safety net after the building was completed took time if the strings and binding wires were unwound, and if it was cut, it would be garbage. The above methods required labor and time because they could not be omitted when setting up safety nets on scaffold pipes and dismantling them. This was extremely annoying for the workers.

[0003]

[Problems to be solved by the invention]

 The present invention seeks to develop metal fittings that can be used for a long time without garbage by minimizing the effort and time required to put a safety net on the scaffold pipe or dismantle it.

[0004]

[Means for Solving the Problems]

 Now, the solution will be described with reference to the drawings. (A) The upper part of the ア ー ム -shaped arm (4) is bent into ∩-shape to provide the hook (3). (B) Provide a reinforcement arm (6) so that it will not be pulled open by the safety net (9). (C) A ball chain (2) provided with a coil pull spring (1) is provided on one end of the arm (4). (D) Provide a chain stop cut (5) at the opposite end.

[0005]

[Embodiment of the invention]

 Next, the embodiment of the present invention will be described. When the safety net (9) is stretched, the hook (3) is inserted into the net hook hole (8), and the coil pull spring (1) is inserted with the ball chain (2). While feeling the force, wrap it around the scaffold pipe (7) and hook it onto the chain cut end (5) before use. Also, depending on the condition of the scaffold, if the joint of the safety net is not at the standing position of the scaffold pipe (7), or if it is separated, it is necessary to use the ball hook (8) without using the ball chain (2). Hook (3) only. When disassembling the safety net (9), it can be removed simply by pinching and pulling the tip of the ball chain (2).

[0006] In implementing the present invention, the following can be performed. (B) The ∨-shaped arm (4) can be made semicircular so as to correspond to the roundness of the scaffold pipe (7), so that the size of the scaffold pipe (7) can be adjusted. (B) Select a hard and rust-resistant material to cope with moisture and deformation. (C) The work that has been passed through the holes one by one can be done simply by inserting with the hook (3). (D) The work of tying and using a tool can be done simply by hooking the chain stopper (5) with a ball chain (2) with a coil pull spring (1).

[0007]

[Effect of the invention]

 Therefore, it is a fitting that replaces the straps and binding wires that can save labor and time when setting up a safety net on a scaffold pipe or dismantling it.
