PROBLEM TO BE SOLVED: To provide temporary scaffolding which enables tread rows of the temporary scaffolding, surrounding a building, to be set longitudinally and laterally flush with each other, which prevents a step from being made at a corner portion, and which enables a beam member for a handrail to be also arranged in the same height position. SOLUTION: A beam 6 for a corner has to be locked to first and second binding holders 8 and 9 of first and second specific supports 2p and 2q, the directions of which are different from each other by an angle of 90°, so that the step can be prevented from being made between treads 3 arranged at the corner portion where the two tread rows cross each other in the temporary scaffolding. Constitutionally, the overall lengths of the right and left wedge pieces 12b and 12a of the beam for the corner are misaligned by the vertical widths of the first and second binding holders 8 and 9. The tread 3 is laid by arranging the beam 6 like this as a beam for the tread at the corner portion. Since the handrail has to be provided in a position above the tread 3, the beam 6 for the corner is turned upside down and laid between the specific supports 2p and 2s. COPYRIGHT: (C)2011,JPO&INPIT
