Zusammenfassung:To provide a device for locking hooking means at a prescribed position in a positioned state in a temporary scaffold, when loading the hooking means of the scaffold board at the prescribed position in the axial direction of a horizontally installed support pipe.SOLUTION: In a temporary scaffold loaded with hooking means of a scaffold board at a predetermined position (P) in the axial direction of a support pipe, the support pipe (1a) has restriction means (11) consisting of a restriction pin (12) having a stopper part (13) facing to a side face of hooking means (8) loaded at the prescribed position. The restriction pin (12) is slidably supported on the support pipe between a protrusion position (M1) with the stopper part protruded by a prescribed height from an upper face of the support pipe and a retreated position (M2) moved downward from the protruded position. Normally, the restriction pin is held at the protrusion position (M1) by spring means (15), and when a downward external force is applied to the stopper part, the pin is moved to the retreated position (M2) resisting against the spring means.SELECTED DRAWING: Figure 2 【課題】仮設足場において、横向きに設置された支持管の軸方向の所定位置に足場板のフック手段を搭載する際、フック手段を所定位置に位置決め状態で係止するための装置を提供する。【解決手段】支持管の軸方向の所定位置(P)に足場板のフック手段を搭載した仮設足場において、前記支持管(1a)は、前記所定位置に搭載されたフック手段(8)の側面に臨むストッパ部(13)を備えた規制ピン(12)から成る規制手段(11)を設けており、前記規制ピン(12)は、前記ストッパ部が支持管の上面から所定高さだけ突出する突出位置(M1)と、該突出位置から下方に移動した後退位置(M2)との間で、摺動自在として該支持管に支持され、常時は、スプリング手段(15)により突出位置(M1)に保持され、ストッパ部に下向きの外力が作用したとき、スプリング手段に抗して後退位置(M2)に移動するように構成されている。【選択図】図2
