<P>PROBLEM TO BE SOLVED: To attenuate vibrations of a wooden house in an earthquake. <P>SOLUTION: In order to solve the problem, the present invention provides an embedded type base isolation device for a wooden house used by fixing, to a foundation of a structure and the middle of an upper base and a column, an isolation device formed by providing a cylindrical rigid body with an open upper surface for which a part projected from a base concrete upper surface is made thicker than a part buried in base concrete, internally fitting an elastic material inside the cylindrical rigid body at the part to be buried in the base concrete, turning the elastic material to such a height that it is projected from the cylindrical rigid body, vertically separately fixing an anchor bolt connected to a building structure member and an anchor bolt fixed to the base concrete to a center part of the elastic material, and joining and internally fitting an elastic material of a different elastic coefficient between the inside of the cylindrical rigid body projected from the base concrete upper surface and the elastic material further. <P>COPYRIGHT: (C)2013,JPO&INPIT |
