The present invention relates to a vibration control building configured by arranging a plurality of building units adjacent to each other and a vibration control material used for the vibration control building.
[0002]
[Prior art]
Conventionally, a damping building and a damping material used for the damping building as described in JP-A-5-321512 are known.
[0003]
In such a case, as shown in FIG. 15, a plurality of substantially box-shaped building units 4, 4 in which long beam members 2, 2 and column members 3, 3 are connected on the foundation 1. Are arranged adjacent to each other.
[0004]
Further, between the foundation 1 and each building unit 4, vibration isolating materials 5 and 5 that absorb vibration are interposed. The vibration isolator 5 has a substantially square shape when viewed from above, and is formed in a thin plate shape in which hard rubber layers and iron plate layers are alternately laminated.
[0005]
Further, in this conventional apparatus, a plurality of the vibration isolating materials 6a and 6b are also interposed between the building units 4 and 4.
[0006]
Next, the effect | action of this conventional damping building and the damping material used for this damping building is demonstrated.
[0007]
In the conventional structure configured as described above, the vibration isolating materials 5 and 5 are interposed between the foundation 1 and each building unit 4.
[0008]
Also, since a plurality of the vibration isolating materials 6a and 6b are interposed between the building units 4 and 4, distortion of the beam materials 2 and 2 is prevented, and vibration during an earthquake or the like Since it is absorbed by each vibration isolating member 5, 6a, 6b, the shaking of the building can be reduced.
[0009]
[Problems to be solved by the invention]
However, in such a conventional technique, it is necessary to interpose substantially rectangular vibration isolating materials 6a and 6b on each of the beam direction facing surface and the wife direction facing surface of the building units 4 and 4, respectively. In addition to the material 5, there is a problem that the number of the vibration isolating materials 6a and 6b increases.
[0010]
Moreover, between the building units 4 and 4 in which the pillar material 3 and the beam material 2 have different thicknesses, the thickness of the vibration isolating materials 6a and 6b must be different. For this reason, it took time and effort to prevent the vibration isolator 6a and the vibration isolator 6b from being mistakenly attached.
[0011]
The present invention was made paying attention to such problems in the prior art, and provides a vibration-damping building that suppresses an increase in the number of parts and has good workability, and a vibration-damping material used for the vibration-damping building. The purpose is to do.

[0013]
In the structure according to claims 1 and 2, the vibration damping material having a long shape is sandwiched between the pillar members of the adjacent building unit along the longitudinal direction of the pillar member. As a result, vibration during an earthquake or the like is absorbed by the damping material to reduce the shaking of the damping building.
[0014]
Since the vibration damping material has a long shape along the longitudinal direction of the pillar material, the vibration damping material is affixed to substantially the entire vertical length of the pillar material.

And the damping material may be interposed, and the number of parts can be reduced.
[0020]
Also, those described in claim 2, the ends of the damping material, is characterized in that is protruded from the end face of the pillar, formed of a fixed state sandwiching the end face of the pillar is bent.
[0021]
The pump of Claim 2 thus constructed, an end portion of the damping material, is protruded from the end face of the pillar, since the fixed state sandwiching the end face of the pillar bending,該制vibration Vibration applied in the width direction of the material is also effectively absorbed by the damping material.
[0022]
For this reason, in addition to vibration absorption in the in-plane and out-of-plane directions of the damping material, vibration absorption in two orthogonal directions can be performed, so that either the girder direction or the wife direction of the damping building is in the out-of-plane direction. And the damping material may be interposed, and the number of parts can be reduced.
[0023]
Furthermore, in the thing described in Claim 3 , the damping material used for the damping building of Claim 1 or 2 which laminated | stacked the said viscoelastic body with the metal plate material which exhibits a elongate shape in multiple layers. It is a feature.
[0024]
In the structure according to claim 3 configured as described above, since the viscoelastic body is laminated in a plurality of layers together with a long metal plate, the viscoelastic body is subjected to vibration in an in-plane direction. While absorbing, the vibration of the damping material in the width direction is absorbed by the metal plate.

As shown in FIG. 13, the vibration damping material 38 is configured by alternately laminating iron plates 39 and 39 as metal plate materials and base materials 9, 9 and 9 as viscoelastic bodies. The iron plate 39 as a metal plate material sandwiched between them has a lower end extending a predetermined length below the base materials 9 and 9.
As shown in FIG. 14, the damping material 38 has a lower end portion of an iron plate 39 extending below the base material 9 protruding from the lower end surface of the column member 3, and is bent outward to be a column member. 3 is fixed in a state of being sandwiched between the lower end surfaces.
[0065]
Next, the operation of the third embodiment will be described.
[0066]
In the unit building 37 of the third embodiment, the lower end portion of the iron plate 39 constituting the damping material 38 is between the lower end surface of the column member 3 and the foundation 1 on which the building units 4 and 4 are placed. It is fixed in a sandwiched state.
[0067]
In this damping material 38, the base materials 9, 9, 9 are laminated in a plurality of layers together with the iron plates 39, 39 as long metal plates, and therefore in the in-plane direction (girder direction E). The base material 9, 9, 9 absorbs vibration, and vibration applied to the damping material 38 in the lateral width direction (wife direction F) is also absorbed by the metal plate 19.
[0068]
Table 3 below shows that the displacement and acceleration of the unit building 37 at the time of an earthquake can be reduced to about 1/3 of the normal seismic design in both the wife direction and the girder direction. Thereby, while preventing damage to the unit building 37, fall of interior objects, such as furniture, can also be prevented.
[0069]
[Table 3]

[0070]
For this reason, since vibration absorption in two orthogonal directions can be performed together with vibration absorption in the in-plane / outside direction of the damping material 38, one of the girder direction E and the wife direction F of the unit building 37 ( In the third embodiment, it is only necessary to align the in-plane and outer directions in the girder direction E) and interpose each damping material 38, 38, and the number of parts can be further reduced.
[0071]
Other configurations and operational effects are substantially the same as those of the first and second embodiments, and thus the description thereof is omitted.
[0072]
As mentioned above, although Embodiment 1, 2, 3 and each modification of this invention were demonstrated based on drawing, this invention is not limited to the said Embodiment 1, 2, 3, and this invention. Any design changes that do not change the gist of the present invention are included in the present invention.
[0073]
For example, in the first embodiment, the damping material 8 is formed by laminating the base materials 9 and 9 and the iron plate 10 which are constituted by three layers, and in the modified example, the damping material 18 is constituted by five layers. However, the present invention is not limited to this. For example, even if the base material 9 is constituted by other multiple layers such as a single layer, two layers, four layers, etc., the longitudinal direction of the pillar 3 The shape, quantity, material, and the like are not limited as long as they have a long shape along the direction.
[0074]
【The invention's effect】
As described above, according to the first and second aspects, the vibration damping material having a long shape along the longitudinal direction of the pillar material is disposed between the pillar materials of the adjacent building units. Since they are sandwiched, vibrations during an earthquake or the like are absorbed by the damping material to reduce the shaking of the damping building.
[0075]
Since the vibration damping material has a long shape along the longitudinal direction of the pillar material, the vibration damping material is affixed to substantially the entire vertical length of the pillar material.
[0076]
For this reason, it is possible to absorb the distortion between building units arranged adjacent to each other effectively with a small amount of vibration damping material, and like a conventional one with a vibration damping material interposed between the beam materials. There is no need to prepare a plurality of anti-vibration materials having different thicknesses, an increase in the number of parts can be suppressed, and there is no risk of erroneous mounting.
[0077]
Therefore, workability is also good.
[0078]
Moreover, in what was described in Claim 1 , the lower end of the said damping material is connected with the foundation in which the said building unit is mounted, Moreover, in the thing of Claim 2 , the said damping material The end portion of the damping member is protruded from the end surface of the column member, and is bent and fixed in a state of being sandwiched between the end surfaces of the column member. Therefore, vibration applied in the lateral width direction of the damping member is also effectively suppressed by the damping member. Absorbed.
[0079]
For this reason, in addition to vibration absorption in the in-plane and out-of-plane directions of the damping material, vibration absorption in two orthogonal directions can be performed, so that either the girder direction or the wife direction of the damping building is in the out-of-plane direction. And the damping material may be interposed, and the number of parts can be reduced.
[0080]
Furthermore, those described in claim 3, wherein the viscoelastic body, together with the metal plate exhibiting an elongated, multiple layers, since they are stacked, the vibration of the surface and out direction together with the viscoelastic member absorbs The vibration in the width direction of the damping material is absorbed by the metal plate material.
[0081]
For this reason, the increase in a number of parts is suppressed and the practically useful effect that the damping material used for a damping building with favorable workability is provided is exhibited.
