Description

  The present invention is attached to a joint made of a vertical member such as a column in a wooden frame structure such as a wooden building constructed by a wooden frame construction method and a horizontal member such as a beam, a girder, a large pull, and a foundation. The present invention relates to a damper for a joint used when reinforcing the joint and improving the earthquake resistance of a structure such as a building.

  As the damper attached to the joint portion of the wooden frame structure constructed by the wooden frame construction method, for example, a first hard plate having a column fixing portion fixed to a column, and a horizontal member fixed to the horizontal member There exists a viscoelastic damper of patent document 1 which consists of a 2nd hard board which has a fixing | fixed part, and a sheet-like viscoelastic material layer laminated | stacked between the 1st hard board and the 2nd hard board.

  However, there is a limit to the external stress that can be absorbed or relaxed by a single viscoelastic damper. For example, it can be attached to a portion with high rigidity attached to a portion to which a large external stress is applied and a portion to which a small external stress is applied. It is necessary to produce a plurality of dampers such as dampers with low rigidity according to the magnitude of external stress applied to the joint, and it takes time and effort to produce the damper for the joint. Not only will the production cost be high. Further, the viscoelastic material layer is molded with a single type or a plurality of types of compositions selected from, for example, natural rubber, isoprene rubber, butylene rubber, SBR, NBR, EPDM, polyurethane, silicone rubber, butadiene rubber, chloroprene rubber, and the like. It must be difficult to adjust to a stiffness suitable for absorbing or mitigating external stress.
