PROBLEM TO BE SOLVED: To simplify the structure of a cylindrical reinforcement body which extends matching an inner wall surface surrounding an inside cavity part of a hollow cylindrical structure.SOLUTION: A reinforcement body 1 is so shaped as to have a cylindrical part 3 which is formed of a material made of high-strength fiber cylindrically to a peripheral length equal to or larger than a peripheral length of an inner wall surface 13, surrounding an inside cavity part 12 of a hollow cylindrical structure 11 such as a concrete electric pole, of the hollow cylindrical structure 11 to be pressed against or bonded to the inner wall surface 13, and has a part of the cylindrical shape coupled with a coupling member 2 and having a peripheral length equal to or less than the peripheral length of the inner wall surface 13. Yarn, an adhesive, a binding band, a staple, etc., is applicable as the coupling member 2 as long as the coupling by the coupling member 2 is released when the cylindrical part 3 of the reinforcement body 1 is pressed against or bonded to the inner wall surface 13. One or a plurality of places in a peripheral direction or an upper/lower end direction of the reinforcement body 1 are considered as a place of the coupling by the coupling member 2.SELECTED DRAWING: Figure 2 |
