One end and the other end of the both arm plates are alternately opened and closed with the hinge interposed therebetween. One end of the both arm plates is a metal fixture fixing portion, and the other end is an attached frame assembly temporary object attachment. Since the mounting bracket is attached to the intersection of the vertical frame member and the horizontal frame member of the framed scaffold, by opening the bracket fixing portion side, the gripping arm portion and the straddling portion are connected to the vertical frame. It can be easily and quickly fitted into the material and the horizontal frame material, and the removal is simple and easy.

According to the third aspect of the present invention, the upper end of the bolt mounting plate is provided with a pin locking groove for locking the support pin mounted on a required portion on one end side of the temporary attached frame.
When attaching the auxiliary frame temporary object mounting portion to the mounting bracket, the above-mentioned support pins are hooked into the pin locking grooves of the mounting bracket, so that the bolts on the bolt mounting plate portion side can only be easily mounted. No, as long as the support pins are hooked in the pin hooking grooves, the bolts on the bracket fixing part side and the bolts on the bolt mounting plate side may become loose after installation of the auxiliary frame temporary, Even if it is likely to fall off, neither the bracket fixing part side nor the load receiving stage mounting part side is opened, which is extremely safe.

According to the fourth aspect, the upper end portion of the bolt mounting plate is provided with a plurality of upper and lower bolt insertion holes, so that the position and inclination of the mounting portion on the side of the attached temporary structure can be adjusted. Installation can be performed.

According to the fifth aspect, since the straddling portion of the bracket fixing portion has the arc-shaped fitting portion corresponding to the outer peripheral surface shape of the horizontal frame member of the framed scaffold, the straddling portion is accurately formed on the horizontal frame member. The fitting can be performed, the mounting direction of the mounting bracket can be more reliably determined, and the mounting bracket can be mounted in a more stable state without rattling.

According to the sixth aspect of the present invention, the gripping arm portion of the metal fitting fixing portion is provided with an opening for releasing the vertical frame member connecting pin projecting from the vertical frame member of the frame scaffold. Even when the vertical frame material connecting pin protrudes from the metal member mounting position of the frame material, the mounting metal can be mounted without being obstructed by the pin.
