PROBLEM TO BE SOLVED: To solve such a problem that conventional scaffolds have a simple structure but can be used only in a low level and also can be used at a height of several meter or higher but to the contrary, the member requires many assembling man-days. SOLUTION: The invention focusses on an ordinary low level house and makes use of features of the structure. That is, (1) by reinforcement bracket to a window frame or a column of house of the window frame side, a single plane partial temporary structure can be constructed, and (2) by a temporary installed column provided with a ladder rung and a structure of the wall scaffold rotating more than the horizontal direction, the space between the wall of the house and the temporary column is used for a passage, by making use of the inward rotary moment acting on the temporary column, even it is one sided scaffold , it is hardly fall. And further, by the above (2) the cage of the ladder is eliminated. By these structures, the number of necessary members can be restricted. The cost at preparation time is reduced and construction time is spared, and effect of spatial spare on containing can be obtained. COPYRIGHT: (C)2006,JPO&NCIPI
