SUPPORTING STRUCTURE OF INSPECTING SCAFFOLD FOR BOILER FURNACE

PROBLEM TO BE SOLVED: To eliminate assembling and dismantling operations for a provisionally erected scaffold and facilitate inspection, etc., of the inside of a furnace hopper. SOLUTION: A supporting structure concerned 21 is composed of a horizontal base frame member 22, vertical column members 23 supported at its four corners, diagonal members 24a, 24b borne at the four corners, and a scaffold 25 laid on the horizontal base frame member 22, and is installed in such a way that one folding support frame body 21a, not illustrated, is formed. The bottoms of vertical columns 23 of other support frame bodies 21b, 21c are engaged by the top of the diagonal member 24a of the support frame body 21a, not illustrated, and the frame bodies 21b, 21c are stacked, and in the same manner, other support frame bodies 21a-21c are installed one after another and assembled. Thus the intended supporting structure 21 is constituted. Because this does not require any assembling and dismantling operations for temporarily erected scaffold, the overall construction term for the inspecting scaffold can be shortened, and it is possible to make inspection of the hopper part at one time.
