Abstract

The present invention relates to a seismic reinforcing device capable of conveniently conducting reinforcement of a structure, the device includes an upper support installed on an upper horizontal portion configured to connect columns, a lower support disposed under the upper horizontal portion, installed on a lower horizontal portion configured to connect the columns, and disposed in a diagonal direction with respect to the upper support, and a damper coupled to the upper support and the lower support and configured to absorb a shock.

First claim

What is claimed is:

1 . A seismic reinforcing device comprising:
an upper support installed on an upper horizontal portion configured to connect columns; one or more lower supports installed on a lower horizontal portion, which is disposed under the upper horizontal portion and connects the columns, and disposed in a diagonal direction with respect to the upper support; and dampers coupled to the upper support and the lower supports and configured to absorb a shock.

2 . The seismic reinforcing device of claim 1 , wherein the upper support includes:
side supports respectively installed on both ends of the upper horizontal portion; and a central support installed on the upper horizontal portion and disposed between the side supports, wherein the lower supports are disposed between the side supports and the central support in a horizontal direction.

3 . The seismic reinforcing device of claim 2 , wherein the dampers are disposed between the upper support and the lower supports in a zigzag shape.

4 . The seismic reinforcing device of claim 3 , wherein the dampers are disposed between the columns to have a “W” shape.

5 . The seismic reinforcing device of claim 1 , wherein:
the upper horizontal portion includes an upper horizontal bar configured to connect the columns and an upper slab configured to cover the upper horizontal bar; and the upper support includes: an upper steel plate disposed on a bottom surface of the upper horizontal bar; an upper protruding plate extending downward from the upper steel plate; an upper damper fixing portion configured to fix the damper to the upper protruding plate by adjusting a rotation angle of the damper; and an upper steel plate fixing portion configured to fix the upper steel plate to the upper horizontal bar.

6 . The seismic reinforcing device of claim 5 , wherein the upper steel plate fixing portion includes:
one or more upper fixing heads seated on the upper slab; an upper fixing penetrator configured to extend from the upper fixing head, configured to pass through the upper slab and the upper steel plate, and disposed on an outside of the upper horizontal bar; and an upper fixing coupler screw-coupled to the upper fixing penetrator and configured to press the upper steel plate.

7 . The seismic reinforcing device of claim 1 , wherein:
the lower horizontal portion includes a lower horizontal bar configured to connect the columns and a lower slab configured to cover the lower horizontal bar; and the lower support includes: a lower steel plate disposed on a top surface of the lower slab; a lower protruding plate configured to extend upward from the lower steel plate; and a lower damper fixing portion configured to fix the damper to the lower protruding plate by adjusting a rotation angle of the damper.

8 . The seismic reinforcing device of claim 7 , wherein the lower support further includes a lower steel plate fixing portion configured to fix the lower steel plate to the lower horizontal bar.

9 . The seismic reinforcing device of claim 1 , wherein the damper includes:
a damper upper coupler coupled to the upper support; a damper lower coupler coupled to the lower support; a damper hydraulic portion configured to connect the damper upper coupler and the damper lower coupler and having a length adjusted by hydraulic pressure; and a damper elastic portion configured to elastically support the damper upper coupler and the damper lower coupler.

10 . The seismic reinforcing device of claim 9 , wherein the damper further includes a corrugated damper cover configured to connect the damper upper coupler and the damper lower coupler, configured to cover the damper elastic portion, and having a corrugated shape such that a length thereof varies.
