DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a damping building, which has no local concentration of stress, improves the degree of freedom in the layout of a room, has a small damping structure, and enables more effective damping. About damping building to do.

[0002]

2. Description of the Related Art As one of vibration damping structures, there is a so-called joint damper system in which a connecting bridge or the like is connected between two adjacent buildings via a damper. An example of the joint damper system will be described with reference to FIG. Building 5
The building 1 and the building 52 are connected by a vibration damping device 53, and the vibration damping device 53 includes a connecting bridge 54, a slide device (not shown), and a damper 55. One end of the connecting bridge 54 is tightly fixed to the outer end of the building 51, and the other end is supported by the outer end of the building 52 via a damper 55.
This joint damper system is used for building 51 and building 5
By using the difference in the vibration characteristics between the two, vibration is canceled by canceling vibrations due to different movements of the building 51 and the building 52 via the vibration damping device 53.

In this joint damper system, since a building is used, there is no need to separately install a heavy object above the building as in a mass damper, and a vibration damping device is provided outside the building, so that the inside of the building can be used freely. There is an advantage that the degree of freedom in layout can be improved.

[0004]

However, such a joint damper system is used to transmit vibrations of a building to another building by a vibration damping device outside the building, so that a joint between the vibration damping device and the building and a damping system are required. Since a large stress concentration occurs in the vibration control device, it is necessary to make the structure of the connecting portion between the vibration control device and the building and the structure of the connecting bridge which is a part of the vibration control device strong. In addition, since the difference in the vibration characteristics of the buildings is used, this joint damper system can be used only when two buildings are adjacent to each other. In addition, there is a drawback that if there is an excellent mode in the several-order mode of the vibration of the building, it cannot be handled.

And the horizontal frame is located on the ceiling below the slab in the upper part of the building.
It is characterized by being installed in well finishing materials . Ma
In addition, one end of the horizontal frame is fastened and fixed in one building,
The other end is fixed in the other building via multiple dampers.
It is characterized by becoming. Further, the vibration-damping building of the present invention is characterized in that horizontal frame members are provided on a plurality of floors.

[0006]

The vibration-damping building of the present invention is constructed as described above, and since a plurality of horizontal frame members and a plurality of dampers are supported and fixed in a dispersed manner, the transmission and absorption of stress are performed at many supporting and fixing points. It is possible to realize a damped building with a slight damping structure without excessive stress concentration. In addition, even in the case of a single building having no adjacent building, the same effect as the joint damper system can be obtained, and the degree of freedom of the indoor layout is improved because the horizontal frame in the building is small. In addition, since the horizontal frame members are provided on a plurality of floors, an effective vibration control building adapted to several-order vibration modes is realized.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing a damping building 1. In the damping building 1, one building is divided into an A building 3, a B building 4, and a C building 5 by an expansion joint 2. Each building is connected by a horizontal frame 6 above the damping building 1.

As shown in FIG. 2, a plurality of horizontal frame members 6 are arranged at predetermined intervals in the horizontal direction, and are fixed to beams of each building. The horizontal frame members 6 are connected to each other by horizontal braces 7 to secure horizontal rigidity. In addition, instead of the horizontal brace 7, the horizontal frame 6
They may be connected to each other or may be connected using a horizontal connecting member.

FIG. 3 shows a fixed state of the horizontal frame member. The horizontal frame 6 is attached to the lower part of the slab 8 above the damping building 1, and in the third building A, the horizontal frame 6 is fastened and fixed to the large beam 9 below the slab 8 via the mounting member 11.
Is fixed via vibration dampers 12 attached to the lower part of the large beam 9 and the lower part of the small beam 10 of the slab 8, respectively. As described above, the plurality of horizontal frame members 6 are arranged below the slab in the horizontal direction, and are fixed at the plurality of locations via the damping dampers 12. It is possible to realize a vibration control building with a light structure without absorbing stress and causing concentration of stress.
Since the horizontal frame member is installed in the ceiling finishing member 13 below the slab 8, the degree of freedom of the indoor layout is also improved.

Next, a detailed example of a vibration damper used in the present invention will be described with reference to FIG. FIG. 4A shows an example in which high damping rubber is used as a vibration damper. The horizontal frame 6 is provided with bolts 14 in loose holes (not shown) in girders 9.
The insertion is fixed so that they can move relative to each other. Between the horizontal frame 6 and the girders 9, high damping rubber 1 is used as a vibration damper.
5 are held to absorb and suppress the mutual movement of the horizontal frame 6 and the girder 9. Instead of the high attenuation rubber 15, an asphalt-based damping material or the like may be used.

FIG. 4B shows an example in which a steel damper is used as the vibration damper. Since the steel damper 16 is in the shape of a hollow truncated cone, it has an effective shape in two horizontal directions. The thickness of the hollow truncated cone is formed so as to increase gradually from the bottom. Thus, it is fixed between the girder 9 and the horizontal frame 6. As the steel damper, a steel damper in which a plurality of steel rods are mounted between plates may be used.

FIG. 5 is a diagram showing an arrangement of a vibration damper. As shown in FIG. 5, the vibration damper 12 may be disposed in any of the divided buildings if one end of the horizontal frame member is tightly fixed in one of the buildings. Further, the number of divided buildings of the damping building is not limited to the embodiment, and may be a two-divided building as shown in FIG. Further, as shown in FIG. 5B, the building may be divided into a central part and an outer peripheral part. In this case, since the expansion joint is provided inside the building, external conditions such as rainfall are taken into consideration. Eliminates the need and becomes more effective.

Further, as shown in FIG. 6, the installation level of the horizontal frame member 6 is not limited to the embodiment, but can be the primary period, the secondary period,
If it is arranged on multiple floors that are dominant in the next cycle, the damping effect will be further improved.
