[0002]

2. Description of the Related Art As a means for improving the seismic resistance of structures such as buildings and houses, a vibration damping structure has been developed in which a hydraulic damper is attached to a brace which is mounted at a diagonal position of a frame and is arranged inside a wall. Is being promoted. In this vibration damping structure, a hydraulic damper absorbs the vibration energy of an earthquake that attempts to plastically deform the frame between columns, beams, and the like, thereby damping the frame of the structure.

FIG. 7 is a front view for explaining a conventional vibration damping device. FIG. 8 is an enlarged view showing a conventional mounting structure of an upper transmission member. FIG. 9 is a longitudinal sectional view taken along line AA in FIG.

[0004] As shown in FIGS. 7 to 9, a conventional vibration damping device 1 is provided, for example, in a wall of a wooden general residential building or the like.
A pillar 2 erected between the first floor and the second floor, a lower beam 3 suspended on the first floor, and an upper beam suspended on the second floor. 4 is attached to a rectangular wall-shaped space 5 (indicated by a two-dot chain line in FIG. 7).

The vibration damping device 1 is interposed between the lower transmission member 6 fixed to the lower beam 3, the upper transmission member 7 fixed to the upper beam 4, and the lower transmission member 6 and the upper transmission member 7. And a hydraulic damper 8 mounted as described above. Hydraulic damper 8
Is mounted so as to attenuate vibration in the direction C parallel to the plane of the wall-shaped space 5.

Further, conventionally, it is necessary to measure the mounting positions of the lower transmission member 6 and the upper transmission member 7 using a measuring instrument such as a gauge or a scale, and thereafter the lower transmission member 6 and the upper transmission member 7 are moved downward. While being in contact with the beam 3 and the upper beam 4, they are fixed to the lower beam 3 and the upper beam 4 with nails or bolts via an L-shaped fitting 9.

Therefore, there is a problem that it is difficult to position the lower transmission member 6 and the upper transmission member 7 with respect to the lower beam 3 and the upper beam 4 because the lower beam 3 and the upper beam 4 are fixed.

In particular, when the upper transmission member 7 is fixed to the upper beam 4, the upper transmission member 7 is pushed up from below and the metal fittings 9 are fixed.
Since it is necessary to pass nails and bolts through the upper transmission member 7
The upper transmission member 7 must be kept stationary until the upper transmission member 7 is completely fixed to the upper beam 4, and thus there is a problem that not only the burden on the operator is large but also the position of the upper transmission member 7 is easily shifted.

In addition, since a plurality of metal fittings 9 are required, the number of assembly parts is increased by that amount, and there is a problem that not only the work of the mounting portion is troublesome but also the cost is high.

Therefore, an object of the present invention is to provide a vibration damping device that solves the above-mentioned problems.

In the vibration damping device, a concave portion is provided in the upper beam or the lower beam for fitting an upper portion of the upper transmission member or a lower portion of the lower transmission member, and an upper portion of the upper transmission member or a lower portion of the lower transmission member is fitted in the concave portion. In this state, the upper transmission member or the lower transmission member is fixed to the upper beam and the lower beam by a fastening member penetrating the concave portion.

Therefore, according to the present invention, the upper beam or the lower beam is provided with a concave portion for fitting the upper portion of the upper transmitting member or the lower portion of the lower transmitting member, and the upper transmitting member or the lower transmitting member is fitted into the concave portion. In order to fix the upper transmission member or the lower transmission member to the upper beam and the lower beam by the fastening member penetrating the concave portion in the combined state, the alignment when fixing the upper transmission member and the lower transmission member to the upper beam and the lower beam Can be performed easily, the labor of the worker performing the mounting work can be reduced, and the working efficiency can be improved.
