[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a vibration damping device that reduces the shaking of buildings due to earthquakes, wind, etc. (Prior art) Building frames and walls deform differently when subjected to horizontal forces during earthquakes, etc. due to the difference in horizontal stiffness. Conventionally, as a vibration damping device that utilizes the relative deformation of the frame and wall at this time, as shown in Figure 6, a hollow PC wall (a) fixed to the floor is filled with a viscous material (b). Viscous body (
Insert the plate (A) whose upper end is fixed to the beam (O) into the inner wall (B), and fill the gap between the inner wall surface of the PC wall and the plate with viscous material, and apply horizontal forces such as earthquakes and wind. proposed a vibration damping device using a viscous body that absorbs vibration energy and reduces shaking by moving the plate inside the viscous body due to relative deformation between the plate and the PC wall. In the figure, (e) is a column.Also, as shown in Figure 8, a steel material (b) with a part that is easily deformed is inserted between the beam (f) and the wall (IiO). It is fixed under the beam and to the wall soil, and when the frame is deformed due to the action of horizontal forces such as earthquakes and wind, the steel members that have easily deformed parts will yield with a small horizontal force, and further horizontal force will be applied. When the steel material undergoes plastic deformation, the hysteresis curve drawn at this time (the first
A vibration damping device has been proposed that reduces the shaking of buildings by absorbing vibration energy (see Figure 0). (Problem to be Solved by the Invention) In the former vibration damping device using a viscous body, the magnitude of viscous resistance generated in the viscous body increases as the gap between the plate and the inner wall surface becomes smaller; The larger the immersed surface area, the larger the surface area, so in order to improve damping performance, the plate needs a large surface area, and if only one plate is used, the entire wall must be used as a damping device. Therefore, when trying to manufacture this vibration damping device, the size is not uniform depending on the building, and the manufacturing process is labor-intensive, resulting in high costs. The latter type of hysteresis damper, which utilizes plastic deformation of steel,
In the event of a large earthquake, there is a high possibility that the damper will be destroyed, and repeated deformation may cause metal fatigue and degrade performance. Furthermore, when a small amplitude is generated due to wind, etc., the steel material is in an elastic range, so it cannot absorb the vibration energy and the vibration damping effect is not exhibited. The present invention has been proposed in view of the problems of the prior art, and aims to be simple to manufacture, miniaturized, and free from fatigue unlike the conventional hysteresis damper. The purpose of this invention is to provide a vibration damping device for buildings that can reduce shaking even when the amplitude is small. (Means for Solving the Problem) In order to violate the above object, the vibration damping device for a building according to the present invention includes a plurality of vertical plates attached to the PC wall or the beam at opposite ends of the PC wall or the beam. are erected at a distance from each other,
In addition, a container filled with a viscous material is mounted, and the container is inserted into the gap between the vertical plates in the container and the gap between the vertical plate and the inner wall surface of the container from the beam or PC wall facing the container. It is constructed with many vertical boards installed vertically. (Function) Since the present invention is constructed as described above, when a building is deformed in the horizontal direction due to an earthquake or wind, relative deformation occurs between the PC wall and the beam, and the inside of the viscous body container is deformed. A large number of vertical plates move within the viscous body, which makes it possible to efficiently absorb vibration energy and reduce the shaking of the building. (Example) The present invention will be explained below with reference to the illustrated example. In Figures 1 and 2, (1) is a steel column, (2) is a steel beam,
A PC wall (3) with sufficiently high rigidity compared to the columns and beams is installed inside the frame constructed by the same columns and beams.
) to the lower beam (2) via the bolt (4). A vibration damping device, which will be described later, is installed between the upper end of the PC wall (3) and the bottom of the upper beam (2).
