現場における足場階段落下防止手摺に関するもの
である。[Detailed Description of the Invention] The present invention relates to a handrail for preventing falls of scaffolding stairs at construction sites, which prevents scaffolds installed at construction sites from falling from the openings of the stairs.
建設現場に設置されている足場は各階への連絡
用の階段が架設されており、この階段部に対応す
る部分には足場板が敷設出来ないためかかる部分
が開口部となり、よつて作業者や資材が開口部よ
り落下する等の事故が発生していた。 Scaffolding installed at construction sites has stairs connecting to each floor, and since scaffolding boards cannot be laid in the areas corresponding to these stairs, these areas become openings, which can cause damage to workers and workers. Accidents such as materials falling from openings occurred.
そこでかかる開口部の周囲に手摺を設けている
が足場を構成するパイプ体は足場板等の種々の部
材が装着されているため、手摺を装着支持せしめ
るスペースが少なく、而も装着必要個所は各階段
部に対応して多数に及ぶためその装着作業には非
常に手間を要する等の欠点を有していた。 Therefore, handrails are installed around such openings, but because the pipes that make up the scaffolding are attached with various parts such as scaffolding boards, there is little space to install and support the handrails, and the places where they need to be installed are different. Since there are a large number of them corresponding to the staircase part, the installation work requires a lot of effort.

大なるものである。 In short, the present invention can be used at a construction site where the handrail body 8 is interposed between the ends of the short rods 4, 4a that constitute both ends of the opening 6 corresponding to the stairs 5, 5a... built on the scaffolding 1. In the scaffold stair fall prevention handrail, the end 15 of the main frame 9 attached to the short rod 4 on the upper side 11 is extended to the front position of the lower side 13, and the standing rod 16 is fixed to the end 15 of the main frame 9. At the same time, the lower end of the upright rod 16 extends horizontally to the lower side 13 and is attached to the short rod 4a, and the side frame 10 is rotatably supported on the upright rod 16 and rotated toward the opening 6 side. Since the lower end of the side frame 10 is attached to the short rod 4a while the main frame 10 is being moved, and a relief portion 25 is provided at the lower corner of the opening 6, the main frame 9 and the side frame 10 are supported at three points. This allows the handrail main body 8 to be stably attached even in a narrow space, thereby preventing accidents of falling from the opening 6 and improving safety during work on the scaffold 1. A triangular plate 26 corresponding to 25 is attached between the side frame 10 and the lower part of the upright rod 16 via pins 29, 29a so that it can rise and fall freely, and is attached to the side frame 10 through a collar 30 to the upright rod 16. Since the plate 26 can be rotated integrally and covers the relief part 25 by falling down toward the relief part 25, the plate 26 allows the relief part 25 to be covered by the relief part 25 when the scaffold is originally narrow. Like the plates 7, 7a..., it becomes a passable part and can widen the scaffolding area, and the attachment parts 12, 18 of the main frame 9 to the short rods 4, 4a are attached to the short rods 4, 4a.
It consists of a ∩-shaped fitting piece 19 that fits into the fitting piece 19, and a wedge body 20 that is inserted through the fitting piece 19, and the attachment part of the side frame 10 to the short rod 4a is made of a clamp 24, so it can be used in narrow spaces. It can be easily attached to the
Its practical effects are great, such as the fact that it can be done with a single touch since it only involves inserting and removing the 0.
