Patent ID: 7647733

Claim:
A building reinforcing structure comprising: first and second structural members for a building connected to each other, a reinforcing member extending between the first and second structural members and fixed to the first and second structure members to form a first space surrounded by the first and second structure members connected to each other and the reinforcing member, said reinforcing member including a first spring member protruding to a direction opposite to a contacting portion between the first and second structural members and a second spring member protruding toward the contacting portion, said first and second spring members forming a second space therebetween, a damper member and a first synthetic resin foam provided in the second space between the first and second spring members, wherein said damper member is arranged to resist against a force enlarging the second space between the first and second spring members due to a force acting on the first and second structural members to reduce an angle at the contacting portion between the first and second structural members, and said damper member and said first synthetic resin foam are arranged to resist against a pulling force reducing the second space between the first and second spring members due to a force acting on the first and second structural members to enlarge the angle between the first and second structural members, and a second synthetic resin foam provided in the first space enclosed by the first and second structural members and the reinforcing member, wherein said second synthetic resin foam resists a pushing force from the second spring member, and a pushing force acting on the first and second structural members to reduce the angle at the contacting portion between the first and second structural members.
