[Structure] A vibration damping device 1 having a mass damper 6 suspended by a damper device such as a tension spring 4 and slidable in two directions of vertical and horizontal directions is mounted on a dry wall board 11, 1.
It exists in having been buried in the space of 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a damping wall for damping vibrations due to external forces such as earthquakes in factories and research laboratories that manufacture high-rise buildings and precision products.

[0002]

[Prior art]

 As a vibration damping device or structure for buildings such as high-rise buildings, a vibration damping device with a passive mass damper that can passively move vibrations due to external forces such as earthquakes in two horizontal directions is used. Those that absorb energy are known.

In such a vibration damping device, a horizontal mass damper is provided on the top floor of a building, and when a vibration damping device having a mass damper that absorbs vertical vibration energy is installed. Had decided to attach the mass damper of the damping device to the beam.

[0004]

[Problems to be solved by the device]

 However, as mentioned above, it is not necessary to separately provide a damping device in the building in the horizontal direction and in the vertical direction in the building, because mass dampers, which are heavy objects, are installed in each building, and the number of mass dampers increases, resulting in waste of equipment and cost. It will be up. In addition, since the vertical damping device is attached to the beam, it becomes a post-construction work for the building, resulting in poor workability. Moreover, there is a drawback in that a large space is required to install a horizontal vibration control device on the top floor of a building, and the top floor site cannot be used effectively.

The present invention has been made in view of the above-mentioned problems, and the mass damper of the vibration damping device is used in two directions of the horizontal direction and the vertical direction to make the device compact, and this is a dry type wall. The purpose is to provide a damping wall incorporated in.

[0006]

[Means for Solving the Problems]

 The gist of the present invention to solve the above problems and achieve the above objects is to have a mass damper suspended by a damper device such as a tension spring and slidable vertically and horizontally. The shaking device is embedded in a dry wall.

[0007]

[Action]

 With such a damping wall, the mass damper can be moved in two directions, and one can also be used as a two-way damper, making it a compact damping device and being embedded in the wall. There is no need to provide a special space for installing the vibration damping device.

[0008]

【Example】

 Next, the present invention will be described with reference to the drawings. 1 is a vertical sectional view of a damping wall of the present invention, and FIG. 2 is a sectional view taken along line AA of FIG. Reference numeral 1 is a vibration damping device, 2 is an outer frame body, 3 is an inner frame body, 4 is a tension spring, 5 is a roller, 6 is a mass damper, 7 is a rail for horizontal sliding, 8 is a rail for vertical sliding, and 9 is a rail. Is a pillar, 10 is a floor, and 11 is a board.

As shown in FIG. 1, the damping wall of the present invention has a damping device 1 built in and embedded in boards 11 of the damping wall. The structure of the vibration damping device 1 is such that the mass damper 6 is suspended in the vertical direction in the rectangular inner frame body 3 by the pulling bars 4, and the side wall of the mass damper 6 and the inner frame body 3 in the left and right direction. A mass damper 6 is supported in a hollow state inside the inner frame body 3 by interposing a rolling element 5 between the rolling element 5 and a vertical sliding rail 8 attached to the inner wall. The rolling element 5 supports a bearing as an example, and is supported by the side wall of the mass damper 6.

The inner frame body 3 is supported in the rectangular outer frame body 2 by a tension spring 4 in the left-right direction, and is horizontally slid on the inner wall of the outer frame body 2 in the vertical direction. , And a rolling element 5 is interposed between the horizontal sliding rail 7 and the outer wall of the inner frame body 3. The rolling element 5 is supported on the outer wall of the inner frame body 3. The outer frame body 2 is fixed to the floor 10 by a mounting plate 12 for reinforcement.

As described above, the vibration damping device 1 is embedded in the space of the dry-wall boards 11 and 11, and the mass damper 6 of the vibration damping device 1 has a vertical vibration and a horizontal two-direction. It will behave in vibration. If such a damping wall is used for the entire wall of a building, the vertical and horizontal vibration energy can be efficiently absorbed by the mass damper 6 of the damping wall even if vibration is applied by an external force such as an earthquake. become.

In one embodiment of the damping wall described above, a tension spring is used, but other known air dampers or oil dampers may be used, and the rolling elements may be omitted in some cases. Of course, the design can be changed without changing the gist of the present invention.

[0013]

[Effect of device]

 As described above, the damping wall according to the present invention is suspended by a damper device such as a tension spring and has a mass damper that is slidable vertically and horizontally. Since it is embedded in a dry type wall, one mass damper effectively absorbs vibration energy in two directions and exhibits a vibration damping effect, which reduces the cost and the vibration damping device is embedded in the wall. As a result, the space for the vibration damping device is not taken on the top floor and beams of the building, and the space of the building can be effectively utilized.
