The first female screw portion 4 is for attaching a bolt 6 for fitting and fixing the notches 3 and 3'to the opening surface of the steel frame 1 which is a C-shaped strut of a building wall panel. At the other end of the steel plate body 2, second female screw portions 5 for mounting the scaffolding connection bolts 7 are provided in parallel with the plate surface of the steel plate body 2.
【００１３】 また、上記鋼板製本体２の板面に直角に形成された第１の雌ネジ部４は、バー リング加工によって形成されている。このバーリング加工は、先ず板面に下穴を 開け、次いでポンチによって所定の穴径のボス孔１１を成形するもので、さらに その後タップでネジを切ることにより、雌ネジに加工している。Further, the first female screw portion 4 formed at a right angle to the plate surface of the steel plate body 2 is formed by burring. In this burring process, a prepared hole is first formed in the plate surface, and then a boss hole 11 having a predetermined hole diameter is formed by a punch, and then a tap is used to cut a screw to form a female screw.
【００１４】 さらに、上記鋼板製本体２の板面に平行に形成された第２の雌ネジ部５は、鋼 板製本体２の板面を半円状の凹面に加工するとともに、同様の半円状の凹面を形 成した雌ネジ用の板状部材１２を上記凹面と対向して取付け、図では凹面の両側 をリベット１３によってカシメ止めしてあり、かつ両者によって形成された円筒 部分１４にタップでネジ切りして形成されている。Further, the second female screw portion 5 formed parallel to the plate surface of the steel plate main body 2 processes the plate surface of the steel plate main body 2 into a semicircular concave surface, and the same half A female threaded plate member 12 forming a circular concave surface is attached so as to face the concave surface. In the figure, both sides of the concave surface are caulked with rivets 13 and a cylindrical portion 14 formed by both is attached. It is formed by tapping.
【００１５】 次にこの考案の足場つなぎ用金具の使用に際しては、先ず鉄骨１を組み上げて 骨格ができた段階で、鉄骨１の開口面に足場つなぎ用金具の切り込み３，３’部 分をはめ込んだ上、第１の雌ネジ部４に取り付けたボルト６を締め付けて足場つ なぎ用金具を固定する。このようにして足場つなぎ用金具を所定の間隔でセット する。足場は、図示はしないが、足場つなぎ用金具の第２の雌ネジ部５に足場連 結用ボルト７を取り付け、この足場連結用ボルト７のナット部１５にボルトで固 定される。Next, when using the scaffolding metal fitting of the present invention, first, when the steel frame 1 is assembled and a skeleton is formed, the notch 3, 3'part of the scaffolding metal fitting is fitted into the opening surface of the steel frame 1. Then, the bolts 6 attached to the first female threaded portion 4 are tightened to fix the scaffolding fitting. In this way, the scaffold-connecting metal fittings are set at predetermined intervals. Although not shown, the scaffold is fixed to the nut portion 15 of the scaffold coupling bolt 7 by attaching the scaffold coupling bolt 7 to the second female screw portion 5 of the scaffold joint fitting.
【００１６】 足場を利用して築造作業を行ない、そして築造作業が完了した後には、足場連 結用ボルト７および足場固定用のボルトを取り外して分解する。Construction work is performed using the scaffold, and after the construction work is completed, the scaffold connecting bolt 7 and the scaffold fixing bolt are removed and disassembled.
【００１７】 足場つなぎ用金具の、足場連結用ボルト７を取付けるための第２の雌ネジ部５ には、必要に応じてプラスチック製キャップをはめ込んでおく。なおこのキャッ プは、第２の雌ネジ部５に錆や目詰まりが生じるのを防止することができる。If necessary, a plastic cap is fitted to the second female screw portion 5 of the scaffold connecting metal fitting for attaching the scaffold connecting bolt 7. This cap can prevent the second female screw portion 5 from being rusted or clogged.
