Abstract

PURPOSE:To effectively damp vibrations of a building by the use of a joint damper, by connecting horizontally adjacent building units with joint dampers to absorb vibrations, in a unit building constituted of a plurality of building units combined with each other. CONSTITUTION:A building unit group 15 is constituted of a building unit 11A and a building unit 11B. And another building unit group 16 is constituted of a building unit 11C and a building unit 11D. Joint dampers 17 are installed between the building unit groups 15, 16. That is, joint dampers 17 are installed between ceiling beams 13 of the building units 11A, 11C and also joint dampers 17 are installed between the floor beam 14 of building unit 11A and the ceiling beam 13 of building unit 11B and also between the floor beam 14 of building unit 11C and the ceiling beam 13 of building unit 11D. Accordingly, when a unit building 10 vibrates horizontally, the dampers 17 operate due to the displacement difference resulting from the vibrations generated between toe building unit groups 15, 16 and as a result, the vibration of the unit building is absorbed by the attenuation characteristic.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit building and a joint damper device which can effectively suppress mainly horizontal vibration (rolling) due to wind, earthquake or traffic vibration.

[0002]

2. Description of the Related Art Generally, as a vibration isolator for a building, there is a Japanese patent publication
There is one using a dynamic vibration reducer such as the invention described in JP-A-63-76932. Further, the joint damper device 1 shown in FIG.
To connect a plurality of independent structures, such as tower-shaped buildings 2 and 3 such as twin buildings, to generate horizontal vibrations (horizontal vibrations) of the tower-shaped buildings 2 and 3 that roll due to wind or earthquake. There are also things to prevent.

[0003]

In recent years, a unit building constructed by assembling prefabricated building units has become widespread as a detached house. However, conventionally, there is no application of the joint damper device to such a unit building.

It is an object of the present invention to provide a unit building in which vibration damping of the building can be effectively performed by using the joint damper device.

An object of the present invention is to provide a joint damper device which can satisfactorily suppress vibration of a unit building and can be easily assembled.

[0006]

According to a first aspect of the present invention, in a unit building constructed by assembling a plurality of building units, horizontally adjacent building units can be damped by a joint damper device. Is combined with.

According to a second aspect of the present invention, in a joint damper device for connecting building units constituting a unit building to suppress the unit building, a damping material having damping characteristics, and a building. It is configured integrally with a mounting bracket that can be connected to.

[0008]

Therefore, according to the unit building of the first aspect, since the horizontally adjacent building units are connected by the joint damper device, when the unit building vibrates in the horizontal direction due to an earthquake or wind, the above Horizontally adjacent building units vibrate independently. As a result, a difference in the amount of displacement due to vibration occurs between the adjacent building units, the displacement difference causes the joint damper to operate, and the damping characteristics of the joint damper can effectively suppress the unit building.

Further, according to the joint damper device of the second aspect, the building units, which are the constituent members of the unit building, are connected by the joint damper, and the joint damper device has the damping material 20 and the mounting metal fitting integrated with each other. Since it is configured as a unit, the unit building can be satisfactorily damped and the joint damper device can be easily attached to the building unit.

FIG. 2A is a cross-sectional view taken along line IIB-IIB of FIG.
It is a sectional view which follows the IIC-IIC line of (A).

As shown in FIG. 1, the unit building 10 is
A plurality of building units 11A, 11B, 11C and 11D, four in this embodiment, are assembled to construct a two-story building. Each building unit 11A, 11B, 11C and 1
The 1D skeleton has four pillars 12, four ceiling beams 13,
The four floor beams 14 are assembled in a box shape, and these intersections are connected by welding or the like.

At the construction site, building units 11B and 1
1D is installed on a foundation not shown, and this building unit 1

And 11B are configured as one building unit group 15, and the building units 11C and 11D are configured as another building unit group 16.

A joint damper device 17 is installed between the building unit groups 15 and 16. That is, the joint damper device 17 is installed between the ceiling beams 13 of the building unit 11A and the building unit 11C, and further, the floor beam 14 of the building unit 11A and the ceiling beam 13 of the building unit 11B, and the floor beam 14 of the building unit 11C. And the joint damper device 17 is installed between the ceiling beam 13 of the building unit 11D. The joint damper device 17 includes a dashpot such as an oil damper and a rubber damping material having a high damping property.

According to the above embodiment, the building unit group 1 of the building units 11A, 11B, 11C and 11D which are adjacent to each other in the horizontal direction of the unit building 10 (direction of arrow A in FIG. 1).
Since 5 and 16 are coupled to the joint damper device 17, when the unit building 10 vibrates in the horizontal direction (the direction of arrow B in FIG. 1; the direction perpendicular to the arrow A) due to an earthquake or wind, the unit building 10 is adjacent to the horizontal direction. Building unit group 15 and 1
6 vibrates independently. As a result, a difference in the amount of displacement based on vibration occurs between the adjacent building unit groups 15 and 16, and the displacement difference causes the joint damper device 17 to operate, and the unit building 10 is operated by the damping characteristic of the joint damper device 17. The vibration can be satisfactorily damped.

The joint damper device 18 shown in FIG.
Two units are installed between the ceiling beams 13 of the building unit 11A and the building unit 11C in the unit building 10. In addition, the joint damper device 19 is the building unit 11A.
