案がされている。(Conventional technology) The seismic isolation structure of a building is a structure that lengthens the natural period of the entire building system by incorporating a laminated rubber layer made of rubber plates and steel plates and a damper that absorbs vibrations into the lower part of the building, which has a short natural period. , aiming to reduce seismic motion input. The laminated rubber has a set allowable deformation amount in response to expected seismic motion input, but if the input is larger than expected, the laminated rubber will deform excessively and break, damaging its seismic isolation function. So, in order to solve this problem,
Conventionally, proposals have been made to control excessive deformation of laminated rubber using a support stand.

収納できる長さＬ２とを加えたものである。 1 and 2, a stopper 1 has a main body composed of a steel cylindrical body 2 and a steel rod 3. As shown in FIGS. A mounting plate 21 is attached to the rear end of the cylindrical body 2, a mounting hole 21a is formed in this mounting plate, and a rod insertion hole 22 is formed at the tip. The length of the cylinder 2 is the allowable deformation L of the laminated rubber.
1 and a length L2 that can accommodate the spring body 4 which is housed and fixed within the tip of the cylindrical body.
ばね体４は、積層ゴムの過大変形を制御するた

ングを用いている。 The spring body 4 is for controlling excessive deformation of the laminated rubber, and in this example, a helical coil spring is used.

付け孔３２ａが形成してある。 The rear end side of the rod 3 is inserted into the insertion hole 22 at the tip of the cylindrical body 2 so as to be movable in the axial direction, and a presser portion 31 is provided at the rear end. A spring body 4 is wound around the rod 3 within the cylinder body 2. At the tip of Rod 3,
A mounting plate 32 is fixedly attached, and a mounting hole 32a is formed in this mounting plate.
次に使用法について説明する。 Next, how to use it will be explained.
ストツパの建物への取付けにおいて、第３図に

ルダンパーＫをストツパ１と平行に取付けてお
く。 In attaching the stopper to the building, as shown in Fig. 3, the mounting plate 32 at the tip of the rod 3 is movable to the lower part of the upper building T, and the mounting plate 21 of the cylinder 2 is movable to the lower structure T1 by means of supporting members. Install it in the correct position and set the whole thing horizontally. In addition, building T
A laminated rubber G is installed between the stopper 1 and the lower structure T1, and an oil damper K is installed parallel to the stopper 1.
またストツパの配置は、第４図に示すように一
方向の変形制御であるため、方向を逆にして２個
のストツパ１ａ，１ｂを１組として配設する。 Further, since the stoppers are arranged to control deformation in one direction as shown in FIG. 4, two stoppers 1a and 1b are arranged as a set with their directions reversed.
地震時に、振動方向が第３，４図矢印Ａ方向の
場合には、ストツパ１ａが作用し、矢印Ｂ方向の
場合にはストツパ１ｂが作用して、変形を制御す

動方向が第４図矢印Ａ１方向および矢印Ｂ１方向
の場合も、ストツパ１ａ，１ｂの作用は、矢印Ａ
方向および矢印Ｂ方向の場合と同様である。 During an earthquake, when the vibration direction is in the direction of arrow A in FIGS. 3 and 4, stopper 1a acts, and when it is in the direction of arrow B, stopper 1b acts to control deformation. In either case, the cylinder 2 is indicated by arrow A (or B)
The spring body 4 contacts the presser portion 31 and suppresses the deformation of the laminated rubber G within the allowable range. Note that even when the vibration direction is in the arrow A1 direction and the arrow B1 direction in FIG. 4, the action of the stoppers 1a and 1b is
The same is true for the direction and arrow B direction.

ＰのＰ１領域の曲線が滑らかになり、またこの勾

域は、ロツドの弾性引張り剛性により最終的な変
形制御を保障する。 If a helical coil spring is used as the spring body 4, the curve in the P1 area of the expected history loop P becomes smooth as shown in FIG. 5, and the slope can be freely adjusted using the spring body. The P2 region then ensures final deformation control due to the elastic tensile stiffness of the rod.

端部側であつてもよい。この例において、第６図

振動方向に移動し（すなわちロツド３との相対的
関係ではロツドが移動し）、押え部３１がばね体
４に当接する。 The storage position of the spring body 4 is the cylinder body 2 as shown in the first figure.
It is not limited to the inside of the distal end, but may be on the rear end side as shown in FIG. In this example, the present invention can be applied when the vibration directions are in the directions of arrows C and D as shown in FIGS. 6 and 7. In this case, the cylindrical body 2 moves in the vibration direction (that is, the rod moves relative to the rod 3), and the holding portion 31 comes into contact with the spring body 4.
