EARTHQUAKE RESISTANT REINFORCING METHOD FOR EXISTING COLUMN

PROBLEM TO BE SOLVED: To improve work efficiency of attached work to the existing column by using divided reinforcing units dividing the circumferential form of the existing column into pluralities, and piling up the existing column in specific height while surrounding the existing column from the circumference. SOLUTION: Reinforced fibers 4 are attached to the inside of a frame body 3 formed in the approximately same shape as that dividing the circumferential shape of the existing column 1 into pluralities or in the shape similar thereto to form divided reinforcing units 2 of proper material having fire resistance in advance. The existing column 1 is surrounded by the divided reinforced units 2 and 2 from the circumference, and after the reinforced fibers 4 attached to the divided reinforcing units 2 are connected to each other, a space S between the existing column 1 and divided reinforcing units 2 is filled with proper filler. The attached work of the reinforced fibers 4 is carried out in a sufficient work space such as plant, etc., and is executed for the inside of the frame body 3 molded with high degree of accuracy. Accordingly, working efficiency is greatly improved, construction days can be reduced and, at the same time, the reduction of working space can be made.
