The present invention relates to a wrapping apparatus for reinforcing a column structure 11 by using a reinforcing material 22, the first driving unit 100, the second driving unit 200, the direction control unit 300, the vertical lift 400 The reinforcing material supply part 500, the spring tension part 600 and the lever chain tension part 700 are connected together to surround the pillar structure 11 in an annular ring shape, and the first driving part 100 and the second driving part 200 In accordance with the driving of the lapping apparatus rotates the surface of the column structure 11 relates to a device for wrapping the reinforcement 22 in the tensioned state automatically on the surface of the column structure 11 and a reinforcement method using the same.

Recently, as a reinforcement method to secure the seismic resistance and durability of column structures such as bridge piers, the bottom seismic reinforcement section of the column structure is wrapped and restrained by using a reinforcement to improve the seismic resistance and load resistance of the piers to collapse the piers in the event of an earthquake. Earthquake-resistant reinforcement work to prevent this is being actively performed.

As a reinforcement method of concrete piers, pillar structures of buildings, etc. which lack strength or seismic reinforcement, reinforcement methods and reinforcement using various reinforcing fibers (glass fiber sheet, carbon fiber sheet, aramid fiber sheet, glass fiber roving yarn, etc.) Reinforcing methods for bonding plates and the like have been mainly used.

Although glass fiber sheet and carbon fiber sheet are very light and have excellent tensile strength, the construction method is made by hand using rollers in the field, so the fiber sheet can be loosely installed, which is the most important element of lapping reinforcement. The effect of tightly restraining the structure, that is, reducing the reinforcing effect, and also the construction of the construction joints of the fiber sheet is continuously generated, there is a problem that the work is cumbersome, structural strength is also weak.

Glass fiber roving lapping can be installed seamlessly with a certain degree of tension, but the existing lapping equipment is a method of installing a track rail at the pier foundation and installing a vertical lift on the rail. Considering the environment, there are very few places where a caterpillar rail can be installed on a bridge foundation. Therefore, the conventional lapping equipment is a situation that the effectiveness of the question is questionable, and also the crawler rail and vertical lift is too heavy, requires a separate heavy equipment for movement and installation, there is a problem in the construction and economical efficiency.
