Definitions
- the present invention relates to a seismic isolation system for a building during an earthquake.
- the "airback type seismic isolation device” of Patent Document 1 described below is a sensor that detects shaking.
- the air-pressure relief is performed by expanding the air bag by the control means such as the above, and the “pneumatic seismic isolation position shift repair device” of Patent Document 2 inflates the air bag, the positional displacement of the upper foundation and the lower foundation after earthquake calming.
- the air tank can be refilled with air by sensing earthquake motion and using it once. In the case of a large earthquake, there is a disadvantage that it can not cope with the subsequent aftershocks.
- Magnetic levitation type seismic isolation device of Patent Document 3 is a device that attempts to obtain seismic isolation effect by using the repulsion of the magnetic force of the magnets provided on the upper and lower foundations. It is energized. Also, there are rolling isolation bearings, laminated rubber bearings, sliding isolation bearings etc. among them as the seismic isolation mechanism of the seismic isolation device. Among them, the rolling isolation bearings use balls, rollers etc. These balls, rollers etc. It is supported by a flat or concave plate and rolled on it, where a plate-like bearing is required.

- This invention is provided in a building, holds the horizontality of the building, for example, in the four corners of the building, directly provides curved surfaces facing symmetrically on the foundation bottom board in contact with the ground and the foundation board on which the building is placed.
- the rolling due to the earthquake causes the sphere to rotate smoothly, rolling on the curved surface to lift the foundation upper floor, to isolate the building, and to return the sphere to the center of the curved surface at the end of the earthquake motion. It is an object of the present invention to obtain a device that can be used continuously and continuously as a vibration isolation device characterized by
- the base bottom 1 in contact with the ground and the base upper board 2 on which the building B is placed are directly provided with curved faces 3, 3 'facing symmetrically and one sphere 7 is arranged at the center.
- the foundation bottom plate 1 moves due to the swing, the sphere 7 rotates smoothly, and the curved surface 3, 3 'rolls, and the foundation upper plate 2 lifts up and does not transmit the swing to the foundation upper plate 2, the building
- the seismic isolation system A is characterized in that it performs seismic isolation and the sphere 7 returns to the center of the curved surface 3, 3 'at the end of the earthquake motion.
- This invention maintains the horizontality of a building during an earthquake or the like, for example, in the four corners of the building, directly provides curved surfaces facing symmetrically on the foundation bottom contacting the ground and the foundation top on which the building is placed.
- 360 ° rolling in all directions by the earthquake causes the spheres to rotate smoothly and roll on the curved surface, and the foundation upper board comes up and does not transmit vibration directly to the foundation upper board side.
- a seismic isolation system characterized by performing seismic isolation of a building and characterized by the fact that the sphere inevitably returns to the center of the curved surface at the end of the earthquake motion, it is ensured that continuous and continuous, all by a simple mechanical construction.
- FIG. 1 is an explanatory view of a seismic isolation system of the present invention.
- FIG. 2 is a plan view of a building provided with the seismic isolation system of the present invention.
- FIG. 3 is a cross-sectional view taken along the line b-b 'of FIG.
- FIG. 1 is a cross-sectional view of the embodiment of the seismic isolation system A according to the present invention (a cross-sectional view along the line aa ′ in FIG. 2), B is a building, 1 is a foundation floor (reinforcement etc.), 2 is a foundation Plates (reinforcing concrete etc.), 3 and 3 'are curved surfaces (The formation of these curved surfaces is directly provided to the foundation base 1 and the foundation upper board 2, but the curved surface is formed by iron plate, hard synthetic resin material etc. 4) is a floor, 5 is a floor, 6 is a supporting wood, 7 is a sphere (for example, made of steel balls). The sphere 7 is one piece between the curved surfaces 3 and 3 '.
- the seismic isolation apparatus A of this invention hold
- the spheres 7 rotate and roll on the curved surfaces 3, 3 ', and the foundation upper plate 2 This rise is not transmitted to the foundation upper board 2 and therefore acts as a seismic isolation without being transmitted to the building located at the top. That is, the building 7 rotates smoothly and rolls the curved surface 3, 3 'in any direction with respect to a roll in the direction of 360 degrees, and does not directly transmit seismic motion to the foundation upper board 2 side. Perform seismic isolation. Then, at the end of the earthquake motion, the sphere 7 always returns to the center of the curved surface 3, 3 '.
- the seismic isolation device of the present invention In the case of a large earthquake, aftershocks often occur following the initial earthquake, but the seismic isolation device of the present invention is perfect because it always operates reliably each time. It is all mechanical and secure in operation, can be provided inexpensively for manufacturing, and is economical. In the seismic isolation system of the present invention, the number of seismic isolation systems is increased or decreased while maintaining the level of the entire building according to the size of the building. In addition, since it does not move against wind sway, no measures are required.

Abstract
Description
図2はこの発明の免震装置を施した建物の平面図である。
図3は図2のb−b’線断面図である。
この発明の免震装置Aは、図2の平面図に示すように、水平を保持してこの例では建物Bの四隅に配置されている。それらの詳細は図1に示すように、地面に接する基礎底盤1と建物を載せる基礎上盤2に対称に向かい合う湾曲面3,3’を直接設け、その中心に一つの球体7を配置する。これによって常時は基礎底盤1に基礎上盤2が自重で動かないようになっている。そして地震によって地盤が上下して横揺れが生じたときに、基礎底盤1が横方向に動いても、球体7が回転し、湾曲面3,3’を転動して、基礎上盤2が浮き上がり、この横揺れは基礎上盤2に伝わらず、したがって上部に位置する建物には伝わらず免震の働きをする。すなわち360度方向の横揺れに対していずれの方向でも、この球体7が円滑に回転し湾曲面3,3’を転動して、基礎上盤2側に地震動を直接伝えないことにより、建物の免震作用を行う。そして、地震動の終了時には球体7は必ず湾曲面3,3’の中心部に戻ることとなる。
