CLAMP FOR SCAFFOLDING
To solve the problem in which a wedge fastening type clamp for scaffolding has a large number of components and mechanical strength is not sufficient in the case of having a flange shape.SOLUTION: In a wedge fastening type clamp for scaffolding, a first pinching piece and a second pinching piece comprising by overlapping two pieces of plate materials are a substantially semicircle shape, and pinch a support pipe from both sides. One end part of the first pinching piece and the second pinching piece is rotatably connected by a pivot pin, and the other end part which is openable is fixed to a support post by being connected by a connection material. One end part of the one pinching piece has a U-shaped cross section, and is rotatable by the pivot pin by sandwiching an overlapping plate part of the other pinching piece. A pipe contact surface has a substantially elliptic shape as a whole, with an upper plate on the overlapping plate protruding and being curved upward, and with a lower plate protruding and being curved downward. This is formed as a bead, and it contributes to increasing strength. At the pinching pieces, wedge holes are formed at object positions respectively.SELECTED DRAWING: Figure 1
【課題】 クサビ緊結型の足場用クランプは、フランジ形状とする場合に、その部品点数が多く、また、機械的な強度が不足していた。【解決手段】 クサビ緊結型の足場用クランプであって、２枚の板材を重ね合わせてなる第１挟持片および第２挟持片は大略半円形であって支柱パイプを両側から挟み込む。第１挟持片、第２挟持片の一端部はピボットピンで回動自在に連結されるとともに、開放可能な他端部は連結材で連結されることで支柱に固定される。一の挟持片の一端部は断面コの字状として、他の挟持片の重ね板部をサンドイッチしてピボットピンで回動自在とした。重ね合わせ板の上板を上に突出湾曲し、下板を下に突出湾曲して、全体として略長円形のパイプ当接面とした。これはビードとして形成し、強度アップに資することとした。各挟持片にはクサビ孔が対象位置に形成してある。【選択図】 図１
