Moreover, the fixing | fixed part 20 fixed to a structural material is formed in this both ends. 1 is a mode in which the first leaf and the second leaf are fixed by the fixing portion 21 with the flat portion of the first leaf being longer than the second leaf. The fixing portions 21 and 20 may be formed with the same length of both the first and second leaves. Further, the fixing portions of the first leaf and the second leaf are generally fixed by a fixing tool such as a bolt or a bolt and a nut.

In the space formed by the first leaf 10 and the second leaf 11 made of plate-like metal members, a plurality of auxiliary metal members 30 having different shapes are combined and arranged. That is, the end portions of the horseshoe shape or semicircular shape are formed into a circular shape with the curved portions of the two auxiliary metal members 32, 32 having a horseshoe shape or semicircular cross-sectional shape as the outside, and are formed inside the circular shape. An auxiliary metal member 33 having an S-shaped cross section is disposed in contact with the horseshoe-shaped or semicircular overlapping portion, and these are combined to be disposed in contact with the curved central portions of the first leaf and the second leaf. And the second leaf and the auxiliary metal member 32 and the auxiliary metal member 33 are connected to each other, and a plurality of auxiliary metal members having different shapes from the first leaf and the second leaf are integrally provided via the fixture 40. It has been. It should be noted that a cylindrical auxiliary metal member having a circular cross-sectional shape may be used instead of the auxiliary metal member having a cross-section horseshoe shape or a semicircular shape.

  The reinforcing member of the present invention is arranged by combining a plurality of auxiliary metal members having different shapes in a space formed between the first leaf and the second leaf constituted by the plate-like metal member, By integrally configuring the leaf and the second leaf and these auxiliary metal members, the auxiliary metal member acts as a damper, and a space between the first leaf and the second leaf is formed. Strengthening the resistance to stress that stretches or compresses, enhances the durability of the reinforcing member, and suppresses the reinforcing effect and deformation that resists deformation of the column structure material when vibration or vibration applied to the building or building becomes large It is excellent in restoring force to restore to a normal position, and it is possible to obtain a reinforcing structure that expresses an excellent effect especially as a reinforcing member of a steel structure, and an effect of improving the durability of a steel structure building or building is expressed.

In the S-shaped auxiliary metal member 33, the central portions of the two S-shaped curved portions are provided. The force in the direction of arrows b and b works. Since the first and second leaves are made of spring steel, they attempt to return to the original direction against the x and x directions by the spring force.

In this case, the two plate-like metal members 10 and 11 and the auxiliary metal members 32 and 33 of the first and second leaves are integrally fixed by the fixture 40 at the curved central portion of the two leaves. In the auxiliary metal member 32, forces in the directions of arrows a ₁ and a ₁ act on the center of the arc of the metal member, and in the S-shaped auxiliary metal member 33, at the center of the two curved portions of the S shape. A force in the direction of arrows b ₁ and b ₁ is applied. Since the first and second leaves are made of spring steel, they attempt to return to the original direction against the x ₁ and x ₁ directions by the spring force. On the other hand, the auxiliary metal members 32 and 33 act as a damper and complement each other, and the reinforcing effect against vibration force and deformation applied to the structural material is enhanced, and the restoring force that suppresses the deformation and restores to a normal position. Is increased.
