Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a seismic retrofitting structure using a reinforcement frame and a vibration pad,

The present invention relates to a structure in which a steel frame is coupled to a column, a girder, and a floor, and a reinforcing frame is additionally installed in the steel frame to reinforce the frame. More particularly, To a reinforcement frame on which various types of reinforcement frames are installed, and to an anti-resisting steel structure using an anti-vibration pad.

Generally, when designing buildings such as houses, buildings, buildings, apartments, etc., seismic design (earthquake-resistant design) for safely protecting structures from earthquakes will be done together.

However, in Korea, the requirement for earthquake-resistant design for buildings was imposed in 1988. Most of the building structures built before the earthquake were not designed for earthquake-resistant design. Even after the earthquake- It is expected that the collapse of the building structure will lead to massive casualties and damage to property.

Various seismic retrofitting methods are applied to minimize human damage and material damage from earthquakes. As a typical vibration damping method, there is a method of installing a vibration damping device. As a vibration damping device, a braced damper is installed diagonally to dissipate energy by the firing hysteresis behavior when a cyclic load is applied. However, in the conventional method of installing the vibration damper, it is necessary to construct a structural member having a large rigidity such as a column or a beam for supporting a brace type damper. Therefore, it is difficult to install, It has the disadvantage of covering the view.

To improve the disadvantages of the brace type damper, an anti-seismic reinforcement method as shown in Fig. 1 has been proposed. As shown in the figure, a rectangular frame hinged to be rotatable at an edge is fixed to the opening of the building, and a damper is installed to absorb the vibration energy at the inner edge of the rectangular frame and to perform the plastic behavior. This method is advantageous in that modularization is possible, and there is a sufficient space for installing a window by minimizing disturbance of view of residents. However, since the frame and the damper support all the loads, the load distribution efficiency against the seismic force is inferior. Further, in order to effectively reinforce the member, a member having a large cross sectional performance is required, and the corner damper still obscures the view.

The present invention has been developed in order to solve the conventional problems as described above, and it is an object of the present invention to improve the seismic performance efficiently by simple construction by connecting the reinforcing frame vertically and horizontally in the steel frame frame installed on the inner surface of the structure There is a technical challenge in providing my progressive steel structure.

Also, the present invention provides a steel frame and a steel structure, which are fixedly connected to each other by an anchor provided with an anti-vibration pad, thereby providing a reinforcement frame for further improving seismic performance and an anti-corrosion steel structure using the anti-vibration pad.

In order to solve the above-mentioned technical problems, the present invention provides a structure for seismically reinforcing an internal space of a structure surrounded by both pillars and an upper girder and a bottom of a lower part, A steel frame attached to the frame; A plurality of fastening members installed at predetermined intervals on the contact surfaces of the steel frame and the structure to fix the steel frame to the structure; And a reinforcing frame installed to a predetermined height from a lower portion of the steel frame at an inner surface formed by installing the steel frame, wherein the reinforcing frame is connected to the bottom of the steel frame And a plurality of horizontal portions orthogonally connected to each other at a predetermined height between a plurality of vertical portions vertically installed at regular intervals and adjacent vertical portions.

Further, in the present invention, the steel frame frame is installed along the longitudinal direction against the inside of the both side columns, or is installed spaced a certain distance from the pillars on both sides thereof. Lt; / RTI >

According to the present invention, the following effects can be expected.

First, by strengthening the inside and the outside in horizontal and vertical directions by using reinforcing frames such as channel members instead of bracing method which connects the corners of the structure to each other as in the conventional method, the resistance against bending and shearing is improved, Greatly improved.

Second, when a steel frame is fixed to a structure using an anchor, a vibration preventing member is used at the joint portion to absorb an action load and an impact, so that the seismic performance can be further improved.
