Description

  The present invention relates to a structure for mounting a vibration control device and a building having the structure.

  Conventionally, in order to improve the earthquake resistance of a building, a vibration control device is provided. This vibration control device is an oil damper or the like that exhibits a damping force corresponding to the speed of the vibration control device. In order to attach this vibration control device to a building, it is possible to maximize the performance of the vibration control device by attaching it with a mounting member having increased rigidity. For example, as shown in FIGS. 6A and 6B as Conventional Example 1, there is an example in which a vibration control device is provided on the brace material or between the moment resistance frames. Conventional Example 2: FIG. As shown in (C), there is an example in which a vibration control device is attached by a wall made of reinforced concrete. A document described in Patent Document 1 is known as a document describing an example of mounting such a conventional vibration control device.

  However, in the conventional mounting structure of the vibration control device, for example, in the first conventional example, the brace material and the frame material may limit the degree of freedom of the building plan. Moreover, in the prior art 2, it is a subject that the cost of an attachment member increases. The vibration damping device mounting structure according to the present invention has been proposed in order to solve such a problem.

The gist for achieving the object by solving the above problems of the mounting structure of the vibration control device according to the present invention is as follows:
The column and beam frame side of the building or the slab side of the building, and the free end side of the mounting member for the cantilever damping device for mounting the damping device on the building are arranged side by side with the damping device. An elastic member that increases the rigidity of the mounting member for the vibration control device and reduces the stress is installed.

  The elastic member includes any one of a coil spring and a viscoelastic body.

And the vibration damping device mounting member is suspended from the ceiling, and the vibration damping device and the elastic member are disposed on the floor side;
The damping device mounting member extends through the ceiling of one floor or through the ceiling of a plurality of floors, and the damping device and the elastic member are disposed on the roof;
The vibration control device mounting member, the vibration control device and the elastic member are disposed outside the building.

  The gist of a building having a vibration control device according to the present invention is that the mounting structure of the vibration control device according to the present invention is formed on a column / beam frame of a building or a slab of a building.

According to the mounting structure of the vibration control device and the building thereof according to the present invention, the rigidity of the mounting member for the vibration control device is increased, and the vibration control effect by the vibration control device is increased.
The elastic member can be easily juxtaposed with the existing vibration control device, and the installation work thereof is simple, and the vibration control effect can be enhanced.
In addition, by controlling the rigidity of the elastic body by design, it is possible to design so as to obtain the same seismic control effect without collecting excessive seismic force on the mounting device for the vibration control device.

  Since the elastic body acts as a fulcrum at the tip of the cantilever mounting member for a damping device, the maximum response as a design value is reduced by about 15%. The generated stress is alleviated, the safety margin of the mounting member is improved, and a cantilever mounting member for a damping device can be configured with a small amount of material, thereby reducing the cost.

  The seismic damper is a tuned viscous mass damper having a mass effect (approximately 1000 times the actual amount) by a rotation amplification mechanism (a viscous mass damper with a rotation amplification mechanism is connected to a structure by a flexible support member to tune the additional vibration system. In which the response is reduced more efficiently than conventional seismic dampers), the effect of stress relaxation is particularly high, and it can be used as a slender mounting device for a seismic control device. It has an excellent effect of contributing to the improvement of the degree of freedom of planning.

It is a front view (A) and (B) which show the outline of the attachment structure of the damping device concerning the present invention. It is a schematic front view (A)-(D) which shows each Example of the attachment structure of the damping device of the same invention. It is explanatory drawing which shows the effect of the attachment member for damping devices in the mounting structure of the damping device which concerns on the same invention. The characteristic curve diagram (A) which shows the relationship between the height of the test body and the acceleration (A) or the relative displacement (B), comparing the mounting structure of the damping device according to the present invention with the conventional structure ( B). It is a characteristic curve figure compared with the case of the conventional structure the input (stress) to the damping device which arises in the attachment structure of the damping device which concerns on the same invention. It is a front view which shows the outline of the attachment structure of the damping device which concerns on a prior art example.

  As shown in FIGS. 1 (A) and 1 (B), a vibration damping device mounting structure 1 according to the present invention includes a vibration damping device 4 provided on a pillar 2 and a beam 3 frame of a building or a slab 7 of a building. On the other hand, the elastic member 5 is juxtaposed with the vibration control device 4.

  As shown in FIG. 1 (A), the pillar 2 / beam 3 frame side of the building and the free end portion 6a side of the cantilever mounting device 6 for the damping device for mounting the damping device 4 on the building are This is a vibration damping device mounting structure 1 in which an elastic member 5 is installed in parallel with the vibration damping device 4 to increase the rigidity of the vibration damping device mounting member 6 and reduce stress. The same applies when the damping force is received by the slab 7 shown in FIG.

  The elastic member 5 is, for example, one of a coil spring and a viscoelastic body. Moreover, the property exhibits the effect as an elastic body in both tension and compression.

  As shown in FIG. 1A, for example, a mode in which the vibration control device 4 and the elastic member 5 are arranged in parallel is mainly conceivable in a mode in a space on the back side of the ceiling. According to this, since the structural members such as the vibration control device 4, the elastic member 5, and the vibration control device mounting member 6 are not arranged in the internal space such as the hallway, the arrangement is neat.

  In addition, as shown in FIG. 2 (A), as a form of arrangement of the vibration control device 4 and the elastic member 5, a vibration control device mounting member 6 is suspended from the ceiling, and the vibration control device 4 and the elastic member 5 Is disposed on the floor side. In this arrangement example, the installation work of the elastic member or the like is easy without being a work at a high place, and maintenance is also easy.

  As still another embodiment, as shown in FIGS. 2B and 2C, the vibration control device mounting member 6 penetrates the ceiling for one floor (a rooftop installation type), or for a plurality of floors. An embodiment is proposed in which the ceiling is penetrated (multi-layer skipping type), each extending, and the vibration control device 4 and the elastic member 5 are arranged on the roof side of the building.

  According to this, indoor space can be utilized widely and efficiently. In this case, the length of the vibration damping device mounting member 6 is increased and the amplitude at the time of the earthquake is also increased. However, by adjusting the rigidity of the elastic member 5 so as to suppress it, The size of the opening (opening for the mounting member for the vibration control device) can be reduced. The internal space of each hierarchy can be used effectively.

  In addition, as shown in FIG. 2D, an embodiment is shown in which the vibration control device mounting member 6, the vibration control device 4, and the elastic member 5 are disposed outside the building. In this embodiment, whether the seismic control device 4 is newly installed or existing, the work of arranging the elastic members 5 side by side keeps people inside the building and disturbs the work of people. It is possible to install the elastic member 5 side by side with respect to the newly installed or existing vibration control device 4 while working inside the building. When earthquake resistance is imparted to an existing building, construction can be performed outside the building, so that it is not necessary to build a scaffold throughout the building, and an earthquake-resistant structure can be easily obtained.

  With the vibration damping device mounting structure 1 according to the present invention, a building A having a vibration damping device formed on the pillar 2 and beam 3 frame of the building can be obtained. By arranging such a vibration control device 4 and the elastic member 5 side by side, as shown in FIG. 3, it becomes possible to halve the stress at the base end portion of the vibration control device mounting member 6. H-1000 × 300 × 19 × 32 mm can be used as the slanting vibration-damping device mounting member 6 as H-600 × 300 × 16 × 32 mm.

  In order to compare the damping effect of the presence or absence of the coil spring by the mounting structure of the damping device according to the present invention with the damping effect in the case of the conventional damping device only structure or the non-damping structure, the height of the mounting member 4A and 4B show the relationship between the acceleration and the relative displacement.

  According to this, the same seismic control effect is obtained in the cantilever mounting device for a seismic control device other than the non-seismic structure. In addition, as shown in FIG. 5, the input to the damping device mounting member 6 is a maximum response value that is a design value compared to the input to a conventional damping device mounting member (such as a frame). The safety margin of the mounting member is improved by about 15%.

  The building having the vibration control device according to the present invention is such that the mounting structure of the vibration control device according to the present invention is formed on a pillar / beam frame of a building or a slab of the building.

  According to the mounting structure of the vibration control device and the building having the same according to the present invention, not only the vibration control device mounting member is made slender when newly installed in the building, but also in an existing building equipped with the vibration control device. Since elastic members can be easily arranged side by side and the vibration control effect can be improved, it can be widely applied to various buildings.
