2. Description of the Related Art Conventionally, when a load receiving stage is temporarily installed on a framed scaffold, a large number of single tubes (single frame members made of steel pipes) are vertically and horizontally and diagonally spaced at a required height outside the framed scaffold. Arrange and fix the single-frame framework scaffold-side connecting part and the single-tube crossing part one by one by pipe clamps to form a side-view substantially inverted triangular stage body consisting of beams and diagonal members, A plywood is laid on the beam portion of the stage body and fixed with a wire or the like, and a handrail is assembled around the beam portion with a single pipe and a pipe clamp in the same manner as described above to form a frame for the load receiving stage.

[0003] In the above-described method, a large number of single pipes and pipe clamps are used to connect the frame scaffold and to perform the frame work of the load receiving stage at a required height from the ground outside the frame scaffold. , The number of pipe clamps becomes several tens, and it takes a lot of trouble and time to work, and because the work of laying the plywood and attaching the handrail at a high position on the outside of the framework scaffold, There was a danger of the worker falling during the work. Furthermore, when the height of the framework scaffold increases as the construction progresses, it is necessary to replace the loading stage with the higher side of the framework scaffold.
Every time the receiving stage is replaced, it is necessary to perform the disassembling operation and the assembling operation of the receiving stage, and the efficiency of the temporary operation of the receiving stage is very poor.

[0004] For this reason, the applicant has previously formed a load receiving stage on the ground in advance, attached a plurality of mounting brackets to the stage mounting positions of the framed scaffold, and mounted the load receiving stage lifted by a crane.
