Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration damper used to attenuate vibrations such as earthquakes, and more particularly, to a vibration damper characterized by using a material excellent in energy absorption capacity and deformation capacity. It is about dampers.

[0002]

2. Description of the Related Art Conventionally, various damping dampers have been used to attenuate vibrations such as earthquakes. Metals, rubbers, and the like have been generally used as materials for such damping dampers.

[0003] However, when a metal is used for the vibration damper, there are problems that the weight is heavy, the molding is troublesome, and the handling is inconvenient.

When rubber is used for a vibration damper,
Rubber has high elasticity, but generally has low rigidity, so that it is difficult to manufacture a vibration damper using only rubber, and there has been a problem that it has to be used in combination with metal or the like.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems in the case of using a metal, rubber or the like for a vibration damper. It is an object of the present invention to easily obtain a vibration damper capable of appropriately attenuating vibration such as an earthquake by using a material that has been used.

[0006]

SUMMARY OF THE INVENTION In the vibration damper of the present invention, in order to solve the above problems,
Therefore, a material made of polyester elastomer was used for the vibration damper.

Here, when a polyester elastomer is used as in the vibration damper of the present invention, the weight is reduced as compared with the case where a metal is used, and it can be easily manufactured by injection molding or the like. In addition, the rigidity thereof is generally higher than that of rubber, so that a vibration damper can be manufactured using only the polyester elastomer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vibration damper according to an embodiment of the present invention will be specifically described below with reference to the accompanying drawings.

(Embodiment 1) In this embodiment 1, as shown in FIG. 1, a beam attachment portion 11 attached to a beam 1 by injection molding or the like using a polyester elastomer (manufactured by Toyobo Co., Ltd .: Perprene P90F). Thus, a vibration damper 10 for a connection, in which a column attachment portion 12 to be attached to the column 2 and a reinforcing bar portion 13 to be bridged between the beam attachment portion 11 and the column attachment portion 12, are integrally formed.

Then, as shown in FIG. 2, at a joint portion where the beam 1 and the column 2 are joined, a beam attaching portion 11 of the damping damper 10 for the joint is attached to the beam 1 with bolts or the like. The column mounting portion 12 of the vibration damper 10 for this connection is mounted on the column 2 with bolts or the like.

When the connection damping damper 10 according to the first embodiment is provided at the connection portion where the beam 1 and the column 2 are joined in this way, when vibration such as an earthquake is applied, the vibration is reduced. Vibration caused by an earthquake or the like is attenuated by the vibration damper 10 made of a polyester elastomer.

(Embodiment 2) In this embodiment 2, as shown in FIGS. 3 (A) and 3 (B), each end has a substantially triangular shape having attachment portions 21a and 22a bent at one end into an L shape. The two steel plates 21 and 22 thus formed are adhered to each other by sandwiching a vibration control sheet 23 made of a polyester elastomer (manufactured by Toyobo Co., Ltd .: Perprene P90F) between the two steel plates 21 and 22. Thus, a damping damper 20 for a connection was obtained.

Then, as shown in FIG. 4, at a joint portion where the beam 1 and the column 2 are joined, a mounting portion 21 provided on one steel plate 21 of the damping damper 10 for the joint is provided.
a to the beam 1 with bolts and the other steel plate 2
The mounting portion 22a provided on the column 2 is mounted on the column 2 with bolts or the like.

When the damping damper 10 for the connection according to the second embodiment is provided at the connection portion where the beam 1 and the column 2 are joined in this manner, when vibration such as an earthquake is applied, two sheets are used. The above-mentioned vibration control sheet 2 provided between the steel plates 21 and 22
3, the displacement between the two steel plates 21 and 22 is regulated, its energy is absorbed, and vibration due to an earthquake or the like is attenuated.

[0015]

As described above in detail, in the vibration damper according to the present invention, since the material made of the polyester elastomer is used, the weight is reduced as compared with the case where metal is used, and the injection molding is performed. By using the polyester elastomer itself, a vibration damper can be easily manufactured by using the polyester elastomer itself.
