Description

The present invention relates to an earthquake-proof device for a building that can be installed in a building such as an existing or new wooden mortar-coated building, a light-weight steel building, or a prefab building.

As an earthquake-resistant device that can be attached to any structure of two or more stories or a one-story building, one disclosed in Japanese Patent Application Laid-Open No. 2003-97083 is known.
JP 2003-97083 A

The earthquake-resistant device disclosed in Patent Document 1 is a curved structure in which a plurality of seismic devices are erected on the ground surface at a position distant from the fabric foundation of the building with a predetermined interval and bent upward toward the building side. It is formed by fixing the front end of a long steel material having a surface to the body of the outer peripheral side of the building, or to the floor.

Since the seismic device disclosed in Patent Document 1 needs to erect a long steel material on the ground surface at a position away from the fabric foundation of the building, there is a margin for erecting the long steel material. There was a problem that the ground had to be built and construction was not possible at the place where the building was built.

The present invention provides a reinforcing member erected by fixing a bottom portion in a foundation recess recessed in an outer ground close to a fabric foundation, for a structure such as a wooden mortar-coated building, a lightweight steel building, or a prefab building. The most important feature is to integrally connect and fix to the pillar material in both the corner and the entering corner or in contact with the corner.

The seismic apparatus according to the present invention provides the corner reinforcing member in contact with or in contact with both the corners and the corners of an existing or newly constructed structure without a conventional ground. By fixing the bottom part of the fabric to the fabric foundation and integrally connecting and fixing the reinforcing member made of L-shaped steel to the pillar material, the horizontal vibration of the building due to the earthquake and the vertical vibration are absorbed by the reinforcing member. It is possible to obtain a seismic effect by weakening the shaking and vibration of the building.

In addition, since a commercially available L-shaped steel material can be used as the reinforcing member, the manufacturing cost is low, the structure is extremely simple, and the installation work is easy, so the installation cost is low.

Reinforcement members fixed to the foundation provided on the outer ground close to the fabric foundation are in contact with both the corners and corners of the building Connect and fix together.

A first embodiment of the present invention will be described in detail with reference to the drawings. The first embodiment of the seismic device according to the present invention is installed in a corner and a corner of a building such as a wooden mortar-coated building, a lightweight steel building, or a prefabricated building.
