Abstract

A damper for reinforcing earthquake resistance according to the present invention includes a first supporting part mounted in a building structure, a second supporting part mounted on a support structure movably disposed to be separated from the building structure, and disposed to face the first supporting part, and a damper part connecting the first supporting part with the second supporting part and absorbing energy generated by an earthquake.

First claim

The invention claimed is:

1. A damper for reinforcing earthquake resistance, the damper comprising: a first supporting part mounted on a building structure;
a second supporting part movably mounted on a supporting structure disposed to be separated from the building structure and disposed to face the first supporting part;
the second supporting part further having protruding parts that protrude toward the supporting structure;
a damper part configured to connect the first supporting part with the second supporting part and absorb energy generated by an earthquake; and
a plate part that is fixed to the supporting structure and having a plurality of apertures into which the protruding parts are disposed so that the second supporting part is vertically moveable.

2. The damper of claim 1 , wherein the damper part includes:
a first damper fixing part fixed to the first supporting part;
a second damper fixing part fixed to the second supporting part; and
a steel rod damper part configured to connect the first damper fixing part with the second damper fixing part, absorb energy transmitted from the first supporting part, and transmit the energy to the second supporting part.

3. The damper of claim 2 , wherein the steel rod damper part absorbs energy while being deformed by the energy transmitted from the first supporting part.

4. The damper of claim 1 , wherein the plate part includes:
a plate body part; and
a long hole part formed in the plate body part at a position corresponding to each of the protruding parts,
wherein the long hole part is formed in a long hole shape in a longitudinal direction of the building structure.

5. The damper of claim 1 , wherein a shock absorbing part for absorbing shock transmitted from the second supporting part is interposed between the second supporting part and the plate part.

6. The damper of claim 5 , wherein the shock absorbing part is formed of an elastically deformable material.

7. A damper for reinforcing earthquake resistance, the damper comprising:
a first supporting part mounted on a building structure;
a second supporting part movably mounted on a supporting structure disposed to be separated from the building structure and disposed to face the first supporting part; and
a damper part configured to connect the first supporting part with the second supporting part and absorb energy generated by an earthquake;
wherein:
the first supporting part includes a first horizontal part, a first vertical part installed on an end portion of the first horizontal part to be perpendicular to the first horizontal part, and a first closing part configured to close opening sides between the first horizontal part and the first vertical part; and
the second supporting part includes a second horizontal part disposed to be separated from and parallel with the first horizontal part, a second vertical part installed on an end portion of the second horizontal part to be perpendicular to the second horizontal part, and includes a second closing part configured to close opening sides between the second horizontal part and the second vertical part,
wherein the first closing part and the second closing part are each formed in a right triangle shape.
