Title:
UNDERGROUND BEAM BAR ARRANGEMENT METHOD USING VERTICALLY SEPARABLE FRAME FOR UNDERGROUND BEAM BAR ARRANGEMENT AND THE FRAME
Document Type and Number:
Japanese Patent JP2015045131
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an underground beam bar arrangement method that promotes efficiency of bar arrangement work of rebars in an underground beam installation construction, and thereby to achieve saving labor and shortening a work completion time.SOLUTION: First of all, a lower stage frame is disposed by using vertically separable frames, and lower reinforcement rebars 8, 10, 11 are temporarily placed on temporal support rods 7 installed in the position higher than a regular reinforcement position. Next, the upper stage frames are mounted, and the height of the frame upper part is adjusted by nuts 6 screwed in the frame lower part struts. When the height of beams becomes higher, a working scaffolding 19 is installed by using a hook 17 provided in an upper stage frame. Upper reinforcement rebars 20, 21, 22 are arranged on supporting members 15, 15a, 15b of an upper stage frame upper part, and stirrup reinforcements 23 are mounted by being inserted from the downward of the lower reinforcement rebars temporarily placed on the temporal support rods 7, and then core reinforcements 24 are mounted. The lower reinforcement rebars are temporarily lifted and the temporal support rods 7 are removed, and then the lower reinforcement rebars are lowered to the lower ends of the stirrup reinforcements, and the bar arrangement and bundling are performed in the regular reinforcement position.
