Conventionally, in the UK and other countries, rubber bearings with relatively low vertical rigidity have been used in vibration-proof buildings constructed to avoid ground vibrations that occur as a result of pollution. Rubber bearings are interposed between the upper building and the lower foundation to provide vibration isolation from vertical vibrations in the ground.

ような地震国にて採用することはできない。 However, since rubber bearings have very low not only horizontal rigidity but also very low vertical rigidity, when an earthquake occurs, the upper building will be displaced horizontally, and the rubber bearings around the building will expand and contract, resulting in a large rocking displacement (in the direction of collapse) as a whole. displacement). Therefore, such building vibration isolation construction methods cannot be adopted as they are in earthquake-prone countries like Japan.

性作動油等が使用可能である。 The locking stopper A is a cylinder D in which a fluid 12 is sealed between two parallel pressure receiving plates 1, 1.
is installed. In the embodiment, the outer cylinder 2 and the inner cylinder 3
A double-tube cylinder D is used. The outer cylinder 2 is positioned on the outer periphery of the inner cylinder 3 and is slidable relative to the inner cylinder 3.
An O-ring 11 is fitted between the outer peripheral surfaces. As the liquid 12 sealed in the cylinder D, flame-retardant hydraulic oil or the like can be used.

る。 A sub-tank (auxiliary chamber) 13 is provided outside the cylinder D, and communicates with the cylinder D through a communication pipe 14. A flow rate regulating valve 15 is provided in the middle of the communication pipe 14. Although various types of flow rate adjustment valve 15 can be considered, the embodiment shown in FIG.
A spherical stopper 15a is located within this communication tube 14. When the flow of the liquid 12 is slow, the plug 15a does not move and the liquid 12 flows through the flow rate adjustment valve 13.
However, if the flow of the liquid 12 is rapid, the plug 15a closes the communication pipe 14 and dams the flow.

がある。 Other examples of the flow rate regulating valve 15 include, as shown in FIG. 4, an orifice 15c in which the diameter of the communication pipe 14 is increased in the middle, a partition wall 15b is provided in the communication pipe 14, and the diameter of the center of the communication pipe 15 is reduced. It is conceivable that there is a hole in the hole. Such a flow regulating valve 1
5, since a large amount of liquid 12 does not pass through the orifice 15c, the liquid 12 rapidly flows through the flow rate adjustment valve 15.
Not only does this prevent the flow from passing through, but it also has the effect of absorbing energy against the vertical compression of the locking stopper.

体潤滑材層５が構成されている。 A fixed plate 6 is brought into contact with one pressure receiving plate 1 via a solid lubricant layer 5 . This pressure receiving plate 1 has no engagement recess 4, and a solid lubricant 5a such as a fluororesin sheet is laid on the outer surface. A solid lubricant 5a is also laid on one surface of the fixed plate 6, and a solid lubricant layer 5 is constituted by both solid lubricants 5a, 5a.

定板６との間にクリアランスｃが形成される。 A certain clearance c is formed between the other pressure receiving plate 1 and the fixed plate 6. A cylindrical spacer rubber 7 is provided in a protruding manner on the fixed plate 6 in correspondence with the engagement recess 4 of the pressure receiving plate 1. The height of the spacer rubber 7 is higher than the depth of the engagement recess 4, and when the spacer rubber 7 is fitted into the engagement recess 4, a clearance c is formed between the pressure receiving plate 1 and the fixed plate 6.
以上のような構成を有するロツキングストツパ

して設けられたペデスタルに固定する。 A locking stopper A is interposed between the upper building B and the lower foundation C. Locking stopper A is placed on the outer periphery of the seismic isolation and vibration isolation building. The locking stopper A fixes the fixing plates 6, 6 with bolts to a pedestal provided protruding from the raft of the upper building B and the lower foundation C.

以上のような免震防振建物におけるロツキング
ストツパーの作動について説明する。 The operation of the locking stopper in the above-mentioned seismically isolated and vibration-proofed building will be explained.

ことによつて一定に保たれる。 When the rocking stopper A is installed between rafts, a certain clearance c is set between the fixing plate 6 and the pressure receiving plate 1, and the vertical support rubber mounting 8 prevents temperature changes. Even if expansion or contraction occurs due to creep, the liquid 12 is kept constant by slowly passing through the flow rate regulating valve 15 of the communication pipe 14.

防振効果に影響を与えることはない。 Since this clearance c is secured and the vertical rigidity of the spacer rubber 7 is negligibly small compared to the vertical rigidity of the vertical support rubber mounting 8, the clearance c
In the range of , the rocking stopper A does not contribute to the vertical rigidity of the upper building, and the vertical vibration of the ground due to pollution is absorbed by this clearance c, and the rocking stopper A affects the vibration isolation effect against the vertical vibration of the ground. will not be given.

Ｄの圧縮変位を阻止するため、ロツキング変位を
極小に抑える。 When rocking vibration occurs in the upper building B due to an earthquake, the rocking stopper A will be compressed by the vertical displacement of the upper building, and the liquid 12 will rapidly flow from the cylinder D through the communication pipe 14 toward the sub-tank 13. shall be. At this time, the flow rate adjustment valve 15
prevents the rapid flow of the liquid 12 and prevents the compression displacement of the cylinder D, thereby suppressing the locking displacement to a minimum.

並進振動のみとなり、地震による地盤の水平振動
に対して免震効果が得られる。 On the other hand, the upper building B is resistant to earthquake horizontal force due to the combination of the horizontal rigidity of the vertical support rubber mounting 8, the horizontal rigidity of the horizontal support rubber mounting 9, and the horizontal elastic-plastic characteristics of the hysteretic damper 10. Settings can be made so that the response of building B is optimal. As the rocking displacement of Building B is suppressed to a minimum by the rocking stopper A as described above, the vibration mode of Building B is almost exclusively horizontal translational vibration, making it immune to horizontal ground vibrations caused by earthquakes. A seismic effect can be obtained.

ツキングストツパーＡは上部建物Ｂの水平剛性

免震効果を妨げることがない。 At this time, since the solid lubricants 5a and 5a of the solid lubricant layer of the locking stopper A slide against each other, the locking stopper A does not affect the horizontal rigidity (horizontal natural frequency) of the upper building B. ,
It does not interfere with the seismic isolation effect.

This idea has the above-mentioned configuration and uses a cylinder with a flow rate adjustment valve in the middle of the communication pipe that does not cause sudden compression displacement, making it possible to minimize the rocking displacement of the building due to an earthquake. . Since a clearance is formed between one of the fixed plates and the pressure receiving plate, the vibration isolation effect against vertical vibrations of the ground caused by pollution is not hindered. Furthermore, since a solid lubricant layer is provided, the seismic isolation effect in the horizontal direction is not hindered.
