性が高まっている。[Problems to be Solved by the Invention] At present, land prices in Japan, especially in urban areas, have risen abnormally, and due to a chronic land shortage, a pencil-type building as tall as possible on a narrow land has been constructed. Building is becoming commonplace, and the number of such pencil-type buildings is on the rise. However, since the pencil type building is easily shaken by an earthquake or wind load, the importance of the vibration damping device is increasing in order to enhance the habitability and safety of the building.

が無いと云うのが現状である。The building vibration damping device is roughly classified into an active type (active type) and a passive type (passive type). In either case, the conventional vibration damping device is high in size and large in size. Since it occupies a place, it is difficult to secure a space for installing such a vibration control device inside the building. That is, because the land price is high and the construction cost is high, the building owner wants to improve the economic effect of the building, so there is not enough space available, and even if it is necessary, a vibration damping device is installed. The current situation is that there is no place to do it.

つ方が使い易いという考え方もある。Next, the vibration damping device disclosed in the above-mentioned Japanese Patent Laid-Open No. 4-1374 has a small and compact structure in consideration of application to a pencil type building. However, the moving support portion that movably supports the mass block with low friction has a structure in which the rolling of a large number of balls is applied, and this is otherwise expensive. In addition, since the moving bearing has no specific direction for moving the mass block, and thus allows the mass block to be restored in all directions of horizontal 360 °, many spring mechanisms are frequently used at least in four directions at right angles. However, there is a drawback that the installation work is troublesome. Furthermore, the planar shape of a building is usually a flat rectangle, and it is easy to swing in the direction of its short sides, but it is normal for it to hardly swing in the direction of its long sides. Therefore, there is also an idea that it is easier to use the vibration damping device having a specific direction.

See the ◯ mark). Even if the building 1 is provided with the additional mass 8, if the damping of the additional mass 8 portion (the damping action of the viscous damper in the case of the present invention) is small, the response magnification is reduced but the damping effect is still obtained. Is low (see the difference between the Δ and □ marks in FIGS. 5 to 7). Therefore, if an additional mass (mass block 8) is added and the damping amount is adjusted appropriately with a viscous damper, the response magnification is sufficiently reduced and averaged, and a stable vibration damping effect can be obtained. That is, the damper of the additional mass 8 (viscous damper) is arranged so that the cycle of the main vibration system (building 1) and the cycle of the vibration system of the additional mass (mass block 8) match and resonate.
Proper damping effect can be obtained by adjusting the damping amount of.

A horizontal member 9 made of a steel plate having a size of 50 mm, a width of 50 mm, and a length of 300 mm is integrally attached, and is laid between the horizontal members 9, 9 in parallel at positions on both sides of the mass block 2. Guide bars 10 and 10 are provided for each book. A coil spring 11 for tensioning is wound around the central portion of each guide bar 10, and one end of the coil spring 11 is attached to a bar side spring receiver 12 fixed to the guide bar 10 as shown in a partially broken view in FIG. It is fastened. The other end of the coil spring 11 has a frame-side spring receiver 14 fixed to the floor structure frame 4 of the building.
Is fixed to a floating spring receiver 13 that abuts on one side of the. The frame-side spring receiver 14 is configured as a cylindrical guide sleeve that guides the free passage movement of the coil spring 11. The floating spring receiver 13 is a guide bar 1
0 is free. Further, the positions of the bar side spring receiver 12 and the floating spring receiver 13 are diametrically opposite to each other in the two guide bars 10 and 10. In short, when the mass block 8 and the guide bar 10 which is a structural element integral with the mass block 8 move to the right in FIG. 2, the coil spring 11 having the bar side spring receiver 12 on the right side has the floating spring receiver 13 at the left end on the body side. From the time of hitting the spring receiver 14, the coil spring 11 is stretched by pulling and expanding with the rightward movement of the guide bar 10, and this spring force acts as a restoring force. On the contrary, the coil spring 11 having the floating spring receiver 13 on the right side simply moves along with the movement of the guide bar 10 through the body-side spring receiver 13. This point acts with exactly the same symmetry when the mass block 8 moves to the left in FIG.

る。Next, as is apparent from FIG. 4, a relatively shallow mass block 8 containing a viscous liquid 15 such as a polymer viscous substance such as silicon in the approximate center of the upper surface of the mass block 8 is shown. Vat-shaped container 16 elongated in the direction of movement
The viscous damper configured as described above is installed by fixing the trough-shaped container 16 to the upper surface of the mass block 8 upward. On the other hand, the cover 17 covering the viscous damper above
Is fixed to the floor structure body 4 of the building with anchor bolts 18, and thus the cover 17 is an element on the side of the building body. A horizontal resistance plate 19, which is one of the constituent elements of the viscous damper, is a support member 2 fixed to the lower surface of the cover 17.
The resistance plate 19 is fixed to 0, so that the resistance plate 19 is immersed in the viscous liquid 15 of the trough-shaped container 16 and keeps a distance of several mm to several tens of mm from the bottom surface of the trough-shaped container 16. .

The viscous resistance resulting from the viscosity of the viscous liquid 15 acts, and this acts as an action of damping the vibration energy. This vibration damping device is implemented with a compact structure in which the height of the back from the upper surface of the floor structure body 4 of the building 1 to the top end of the cover 17 is as low as about 80 to 100 mm.

The circles in the figure are for the case where the vibration damping device is not installed, and the triangles are for the ratio of the weight of the mass block 8 of the vibration damping device to the building weight is 1 /.
In the case of 1000, the mark □ is the result of execution under the condition that the ratio is 1/100. The mass point period is equal to the primary period of the building, and the equivalent damping of the additional mass point (mass block 8) is 30.
