WEDGE BINDING DEVICE IN SCAFFOLD
To provide a wedge binding device used in a scaffold such as a temporary scaffold .SOLUTION: In a wedge binding device in a scaffold, in a state where a flange (13) is made to advance to a receiving part (20) formed between an upper jaw part and a lower jaw part in a jaw metal fitting (15), a wedge member (16) inserted into insertion holes (21)(22) in the upper and lower jaw parts and a binding hole (14) of the flange is driven to move down to a binding position (P2). By press-fitting a wedge part of the wedge member into a space between a direct support edge part (14a) in the binding hole and receiving edge parts (21a) and (22a) in the insertion holes, abutting parts (18a) and (19a) at the tip of the jaw metal fitting is brought into contact with a column. A retreat position (P0) is the position in which the wedge member (16) is retreated to the upper part of the receiving part so as not to prevent the advance of the flange (13) into the receiving part (20). The wedge binding device has spring means (26) with an elastic retaining member (30) for holding the wedge member in the retreat position, and the holding power of the elastic retaining member (30) is constituted to prevent descent by the wedge member's dead weight and to permit up and down movement of the wedge member by external force.SELECTED DRAWING: Figure 2
【課題】仮設足場等の足場において使用される楔緊結装置を提供する。【解決手段】顎金具(15)の上顎部と下顎部の間に形成された受入部(20)にフランジ(13)を進入させた状態で、上下顎部の挿通孔(21)(22)とフランジの緊結孔(14)に挿通された楔部材(16)を打ち込んで緊結位置(P2)まで下動させ、該楔部材の楔部を緊結孔の接支縁部(14a)と挿通孔の受縁部(21a)(22a)の間に圧入することにより、顎金具の先端の当接部(18a)(19a)を支柱に当接させる構成において、受入部(20)に対するフランジ(13)の進入を妨げないように楔部材(16)を受入部の上方に退避させた位置を退避位置(P0)として、楔部材を該退避位置で保持する弾発保持部(30)を備えたスプリング手段(26)を設けており、前記弾発保持部(30)の保持力は、楔部材の自重による下降は阻止するが、外力による楔部材の上下動は許すように構成されている。【選択図】図２
