Description

この考案は、建物の空気浮揚式免震基礎の浮揚時、浮揚した免震基礎上盤の傾を修正し水平に浮揚させる装置に関する。  The present invention relates to a device for correcting the inclination of a floating base plate of an isolated base and levitation horizontally when the base of an air levitation type base is lifted.

空気圧により基礎を浮揚させる免震装置は、重心の移動や編心により免震基礎上盤が水平に浮揚しない事も有る。  In the seismic isolation device that levitates the foundation by air pressure, the base plate of the seismic isolation foundation may not float horizontally due to movement of the center of gravity or knitting.

この考案は、地震時空気圧により浮揚した免震基礎上盤を、重心の変動などで傾かない様、水平を補正するものである。  This device corrects the level so that the seismic isolation foundation upper plate that is levitated by air pressure during an earthquake will not tilt due to changes in the center of gravity.

この課題を解決する為、この考案は図３の様に免震基礎上盤（２）に複数のスリーブ穴（３）を設け、その内部にピストン（４）を設置し、地震時図２の様に浮揚した免震基礎上磐（２）の傾を、図３の様に空気圧の注入又は、スプリングなどの反発力によりピストン（４）を所定の位置まで押し下げ、免震基礎上盤（２）を水平に浮揚させる。  In order to solve this problem, this device is provided with a plurality of sleeve holes (3) in the base plate (2) for base isolation as shown in FIG. As shown in FIG. 3, the piston (4) is pushed down to a predetermined position by injecting air pressure or the repulsive force of a spring as shown in FIG. ) Levitating horizontally.

本考案は以上の様な構造で、図２の様に地震時空気圧で浮揚した免震基礎上盤（２）の傾を、図３の様に水平維持装置（３、４、５）に空気圧を注入又はスプリングなどの反発力によりピストン（４）を所定の位置まで押し出す事で、免震基礎上盤（２）の傾を直し水平を維持する事が容易になる。  The present invention has the structure as described above. As shown in FIG. 2, the inclination of the seismic isolation base upper plate (2) lifted by the air pressure during earthquake is applied to the horizontal maintenance device (3, 4, 5) as shown in FIG. The piston (4) is pushed out to a predetermined position by a repulsive force such as injection or spring, so that it is easy to correct the tilt of the base plate (2) and maintain the horizontal level.

以下、本考案を実施する為の最良の形態について説明する。
空気浮揚式免震装置の免震基礎上盤（２）に複数のスリーブ穴（３）を設け、その内部にピストン（４）を設置し、地震時空気圧により浮揚した免震基礎上盤（２）が傾きにより沈み下がった位置にある水平維持装置（３、４、５）に空気圧が注入され、ピストン（４）を所定の位置まで押し出す事により免震基礎上盤（２）の傾を修正し、水平を維持する。Hereinafter, the best mode for carrying out the present invention will be described.
A base-isolated base plate (2) with a plurality of sleeve holes (3) in the base plate (2) of the air-floating seismic isolation device, and a piston (4) installed inside it, which is levitated by the air pressure during the earthquake. ) Is tilted down by tilting, air pressure is injected into the horizontal maintenance device (3, 4, 5), and the piston (4) is pushed to a predetermined position to correct the tilting of the base isolation base (2) And stay level.

平常時、空気浮揚式免震装置が基礎底盤（１）と免震基礎上盤（２）が密着している断面図である。  In normal times, the air levitation type seismic isolation device is a cross-sectional view in which the foundation base (1) and the seismic isolation foundation top (2) are in close contact. 地震時、空気浮揚式免震装置に空気が吹き込まれ、免震基礎上盤（２）が基礎底盤（１）より傾きながら浮揚している断面図である。  It is sectional drawing which air is blown into the air levitation type seismic isolation device at the time of an earthquake, and the seismic isolation base top board (2) is levitating while inclining from the foundation bottom board (1). 空気浮揚式免震装置が作動し空気が吹き込まれ浮揚時、本考案の水平補正装置に空気圧が注入され、ピストン（４）の押しだし効果により、傾が修正され基礎底盤（１）より免震基礎上盤（２）が水平に浮揚している断面図である。  When the air levitation type seismic isolation device is activated and air is blown in, the air pressure is injected into the horizontal correction device of the present invention, the tilt is corrected by the pushing effect of the piston (4), and the base is isolated from the foundation base (1). It is sectional drawing which the upper board (2) is levitating horizontally.
