  • Patent number: 7647733
    Abstract: A reinforcing structure for a building and a reinforcing member used for the structure, where the structure has excellent anti-vibration characteristics and quake resistance. The reinforcing structure and member for a building are capable of reducing the deformation of structural members of the building caused by vibration and removing the deformation so that the original form is restored. A reinforcing member (1) is provided and fixed at a corner portion where structural members (11, 12) of a building intersect. The reinforcing member (1) is formed such that a first spring member (third leaf 33) and a second spring member (layered leaf (5)) are combined, and a damper (4) and a synthetic resin foam body (2a) are arranged in a space between the first and second spring members. A synthetic resin foam body (2b) is filled in a space surrounded by the structural members (11, 12) and the reinforcing member (1).

  • Publication number: 20090031666
    Abstract: The present invention relates to a reinforcing member for a building and a construction, which reinforces a structural member in a building and a construction, and reinforced structure using the reinforcing member. The reinforcing member comprises an attaching metal member to a structural member, an energy absorber, and a surface metal member. The energy absorber is held between the attaching metal member and the surface metal member, and integrated with those metal members. Further, the present invention relates to a reinforced structure having a vibration-proofing performance and an earthquake resistance, which comprise the reinforcing member bridged and installed on a joint portion between a post structural member and an another structural member connected to the post structural member.

  • Patent number: 6318031
    Abstract: A recess is formed by excavating ground, and a base support formed by a synthetic resin molded foam is laid in the recess or resin foam concrete is placed in the recess to provide a base support formed by the resin foam concrete in the recess. A plurality of vibration absorbers is mounted on the base support in such a manner as to be parallel to and spaced from each other at specific intervals. The vibration absorber is formed by a plate-like synthetic resin molded foam having a large number of through-holes which pass through the molded foam in the thickness direction or a plate-like synthetic resin molded foam having a large number of gaps between particles. Concrete is placed on the base support on which the vibration absorbers have been mounted, to form a base. The three components, that is, the base support, vibration absorbers, and base are integrated to each other to constitute a base structure of a building.
