Abstract:
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
