のとして最適である。Although the connection part of the wooden frame is substantially pin-jointed, it is easily deformed in the event of an earthquake. However, by installing the damping damper A in the connection part, the wooden frame tends to deform. In such a case, an in-plane relative rotation tends to occur between the two steel plates 1 and 2, and the relative rotation is suppressed by the viscous resistance force of the viscoelastic material 3, and the vibration of the wooden frame is rapidly attenuated. As a result, an excellent damping effect can be obtained.
Since the vibration damper A has only the viscoelastic material 3 sandwiched between the two steel plates 1 and 2, the structure is extremely simple, and the installation to the wooden frame is easy and reliable. It can be carried out and can be manufactured at low cost, and is most suitable for application to small-scale wooden buildings such as detached wooden houses.

Each steel plate 10 is composed of a main body 10a and a mounting portion 10b. By fixing each mounting portion 10b to the side surface of the column 4 and the lower surface of the beam 5, the steel plate 10 can be installed on the surface of the wooden frame, and has excellent fit. is there. However, when the steel sheet is bent into an L-shape in this manner, the bent portion is liable to bend, and the bending deformation of the steel sheet cannot be neglected with respect to minute deformation (about 1 to 2 mm) of the wooden frame. Therefore, it is indispensable to provide a reinforcing rib 11 at the bent portion to reliably restrain bending deformation. By providing such a reinforcing rib 11, each of the above-described vibration dampers can be used. AC
The same damping effect can be obtained.

The direction of the steel plate 10 is changed so that the mounting portion 10b faces the other steel plate 10 side. By attaching the vibration damper E to one side of the column 3 as shown in the drawing, the rear side thereof is mounted. For example, a space for fixing another member such as a strut can be secured.

Each of the steel plates 12 is formed by welding the main body portion 12a and the mounting portion 12b so as to form a T-shape. Such a T-shape is higher in rigidity than an L-shape, so that the above-described reinforcement is performed. The rib 11 may be omitted.

For example, a flat steel sheet 2 and an L-shaped steel sheet 10 can be combined as in a vibration damper G shown in FIG. The T-shaped steel plate 12 and the L-shaped steel plate 10 may be appropriately combined. An L-shaped steel plate 1 instead of the flat steel plate 2 in the vibration damper B shown in FIG.
Of course, it is also possible to use a 0 or T-shaped steel plate 12.

パーの製造方法。13. A method for manufacturing a vibration damper according to any one of claims 1 to 12, wherein a heat-resistant and elastic sealing material is attached to a peripheral portion of one of the steel plates except for an upper portion. At the same time, a viscoelastic material having a heat melting property is arranged in an inner space of the sealing material, the other steel plate is overlapped with the steel plate via a spacer, and temporarily fastened with a bolt to assemble the assembly. A method for manufacturing a vibration damper, characterized in that the entire viscoelastic material is melted and re-solidified between both steel plates by heating the whole in a state in which the damper is raised.
