PROBLEM TO BE SOLVED: To provide an earthquake resistant reinforcement structure capable of using a compressive brace to simplify its joining with an existing building and ensure a sufficient bearing force and reducing cost.SOLUTION: A compressive brace 1 consisting of a core material 2 and restraining materials 3 arranged along both faces of the core material 2 is used as a brace for reinforcement. A pair of half-split steel pipes 11, 11 made by vertically half-splitting a steel pipe, mutually joined by bolts, and surrounding a column 20 in a skeleton of an existing building are provided as a joint member 10 for joining the compressive brace 1 to the skeleton of the existing building. A clearance between the column 20 and the half-split steel pipes 11 is filled with grout 18 to join the half-split steel pipes 11 to the column 20. A horizontal plate 12 welded along the upper or lower end of each half-split steel pipe 11 and extending outward in a flange-like shape is provided and bonded to a beam 30 of the existing building by an epoxy adhesive 19. The core material 2 of the compression brace 1 is bonded to the half-split steel pipes 11. |
