Abstract

PURPOSE: To prevent the local collection of a stress, make a vibration control structure lightweight, and improve the degree of freedom in interior layout by connecting adjacent ridges by a plurality of horizontally dispersed horizontal frame members, fixing one end into one ridge, and the other end into the other ridge. CONSTITUTION: A vibration control building 1 is divided into three of A-ridge 3, B-ridge 4, and C-ridge 5 by expansion joints 2, respectively. The upper parts of the respective ridges are connected by horizontal frame members 6. One end of the horizontal frame member 6 is fixed to a girder 9 through a mounting member 11, and the other end is fixed through a vibration control damper 12 mounted on the lower ends of the girder 9 and a beam 10. The horizontal frame member 6 and the damper 12 are horizontally dispersed, and supported and fixed. Therefore, the transmission and absorption of the stress are performed in the support fixed points to prevent the local collection of the stress. The horizontal frame member 6 can be thus constructed with a lightweight frame, and a joint damper system can be adapted even in a single building.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration-damping building in which stress is not locally concentrated, the degree of freedom in the layout of the room is improved, and the vibration-damping structure is light, enabling more effective vibration damping About the vibration control building.

[0002]

2. Description of the Related Art As one of the vibration control 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
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 utilizing the difference in vibration properties from the vibration damping device 2 and the vibration damping device 53, the vibrations are canceled by the different movements of the building 51 and the building 52, thereby performing vibration damping.

Since this joint damper system uses a building, it is not necessary to separately install a heavy object on the upper part of the building like a mass damper, and since a vibration damping device is provided outside the building, the inside of the building can be used freely. This has the advantage that the flexibility of layout is improved.

[0004]

However, such a joint damper system has a structure in which the vibration damping device and the building are connected to each other in order to transmit the vibration of the building to another building by the vibration damping device outside the building. Since a large stress concentration occurs in the vibration control device, it was necessary to make the structure of the connection between the vibration control device and the building and the structure of the connecting bridge that is a part of the vibration control device strong. Also, since the difference in vibration characteristics of the building is used, this joint damper system can be adopted only when two buildings are adjacent to each other. Further, there is a drawback that it cannot be supported when there are some excellent vibration modes of the building.

[0005]

In the vibration-damping building of the present invention, adjacent adjacent buildings are connected by a plurality of horizontally-distributed horizontal frame members, and one end of the horizontal frame members is tightly connected to one of the buildings. Fixed,
The feature is that the multi-end is fixed to the other building via a vibration damper. Further, the vibration damping building of the present invention is provided with an expand joint for one building to form a plurality of buildings, and the plurality of buildings are connected by horizontal frame members horizontally dispersed.
It is characterized in that one end of the horizontal frame member is tightly fixed in one ridge, and the other end is fixed in the other ridge via a vibration damper. Furthermore, the 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 dispersed and supported and fixed, the stress transmission and absorption at many supporting and fixing points. It is possible to realize a damping building with a slight damping structure without excessive stress concentration. In addition, even in the case of a single building without adjacent buildings, the same effect as the joint damper system can be obtained. Further, since the horizontal frame material in the building is light, the degree of freedom in the indoor layout is improved. In addition, since horizontal frame members are installed on multiple floors, an effective vibration control building adapted to several vibration modes can be realized.

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 member 6 above the damping building 1.

As shown in FIG. 2, a plurality of horizontal frame members 6 are horizontally arranged at a predetermined interval and fixed to the beams of each building. Horizontal braces 7 connect the horizontal frame members 6 to each other to ensure horizontal rigidity. In addition, instead of the horizontal brace 7, the horizontal frame member 6 is made of steel plate.
They may be connected to each other, or may be connected using a horizontal connecting member.

FIG. 3 shows how the horizontal frame members are fixed. The horizontal frame member 6 is attached to the lower part of the slab 8 in the upper part of the vibration control building 1, and in the third wing of the building A, the horizontal frame member 6 is tightly fixed to the large beam 9 below the slab 8 via the attachment member 11.
The other end is fixed via vibration dampers 12 attached to the large beam 9 and the small beam 10 below the slab 8, respectively. As described above, since the plurality of horizontal frame members 6 are horizontally arranged in the lower part of the slab and are fixed at the plurality of places via the vibration dampers 12, the stress is distributed to the plurality of vibration dampers 12 which are dispersed. It is possible to realize a vibration-damping building with a light structure without being concentrated by stress absorbed by
Since the horizontal frame member is installed in the ceiling finishing material 13 below the slab 8, the degree of freedom of layout in the room is improved.

Next, a detailed example of the 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 the vibration damper. The horizontal frame member 6 includes a girder 9, a loose hole (not shown), and a bolt 14
They are fixed so that they can be inserted and moved relative to each other. Between the horizontal frame 6 and the girder 9, a high damping rubber 1 is used as a vibration damper.
5 is held, and absorbs and suppresses mutual movement between the horizontal frame member 6 and the girder 9. Instead of the high damping rubber 15, an asphalt 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, and the wall thickness of the hollow truncated cone is formed so as to gradually increase from the bottom. Is fixed between the girder 9 and the horizontal frame member 6. As the steel damper, a steel damper having a plurality of steel rods mounted between the plates may be used.

As shown in FIG. 5, the vibration damper 12 may be arranged 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 vibration control building is not limited to the embodiment, and may be two as shown in FIG. 5 (a). Further, as shown in FIG. 5 (b), 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. It becomes unnecessary and unnecessary.

Further, as shown in FIG. 6, the level of installation of the horizontal frame member 6 is not limited to that of the embodiment, but the primary period, the secondary period, and the third period.
The vibration damping effect will be further improved by arranging them on multiple floors with outstanding next cycle.

[0014]

According to the vibration control building of the present invention, adjacent adjacent buildings are connected by a horizontal frame material, one end of the horizontal frame material is tightly fixed in one building, and the other end is in the other building. Since it is fixed via a vibration damper, it is possible to horizontally support and fix multiple horizontal frame members and dampers. Since stress can be transmitted and absorbed at many support fixing points, local concentration of stress can be prevented and horizontal The frame can be constructed with a slight frame.

Further, in the vibration-damping building of the present invention, one building is provided with an expand joint to form a plurality of buildings, and the plurality of buildings are connected by a horizontal frame material, and one end of the horizontal frame material is one building. Since it is tightly fixed inside and the other end is fixed inside the other building via a vibration damper, the joint damper system can be adopted even in a single building. And since the horizontal frame material is stored in the ceiling, the degree of freedom in the interior layout is increased.

Further, since the horizontal frame members are provided on a plurality of floors according to the predominant mode of each cycle, the damping effect is further enhanced.
