Claims

[Scope of utility model registration request]

A jig for attaching a suspended scaffold to a precast girder that has a lower flange whose both sides are vertical and whose upper surface is sloped so that it becomes lower toward both ends in the width direction, and the slanted upper surface of the lower flange is attached to the upper end from both sides of the precast girder. A pair of left and right arms each having an engaging part that releasably engages with the precast girder is pivotally connected at the middle part in the width direction of the precast girder so as to be able to swing open and close around a pivot axis in the length direction of the girder. , constitutes an elastic stopper mechanism capable of switching both arms between a closed state in which the engaging portion engages with the inclined upper surface of the lower flange and an open state in which the engagement portion disengages and disengages both arms by an operating force above a certain level; A suspension support member for a suspended scaffold is provided on the pivot axis or a portion thereof in the vicinity thereof, so that the weight of the suspended scaffold acts in the direction of closing both arms.
