PROBLEM TO BE SOLVED: To provide an existing steel pipe column reinforcement material capable of reinforcing the outside and the inside near a corrosion part of an existing steel pipe column to improve the strength thereof and easy to construct.SOLUTION: An existing steel pipe column reinforcement material comprises: a reinforcing pipe 2 surrounding the outer periphery near a corrosion part of an existing steel pipe column, where a mortar filling space is formed between the reinforcing pipe 2 and the existing steel pipe column; a pair of half-split pipes 3 inserted in a vertical direction to the inside near the corrosion part of the existing steel pipe column and divided into two parts in the circumferential direction; and a ring 4 having the same diameter as that of the existing steel pipe column and fitted on the circumference of the pair of half-split pipes 3. The reinforcing pipe 2 consists of a cylindrical body which is continuous in the circumferential direction, and a plurality of screw holes 8 are bored at proper intervals in the circumferential direction in the reinforcing pipe 2. Centering screws 9 are screwed into the screw holes 8 respectively from the outside toward the inside, and the half-split pipes 3 are detachably mounted to the ring 4. The outer diameter of the half-split pipe 3 is formed to be smaller than the inner diameter of the existing steel pipe column and the ring 4. |
