Field of the Invention [0001] The present invention relates to an earthquake-proof reinforcement structure for a building, and more particularly, it relates to an earthquake-proof reinforcement structure for a building, This is about the structure of seismic strengthening of buildings that can minimize human or material damage.
Unlike the high-rise buildings in the downtown area, it is common for the school buildings to be simply constructed with reinforced concrete structures, and the floor height is not very high.
On the other hand, it is general that recently constructed structures, especially school buildings, are constructed by earthquake-resistant design.
However, in the case of the former school buildings, it is not earthquake - resistant and is vulnerable to earthquakes. Therefore, large damage may occur when an earthquake occurs.
Furthermore, considering the large number of people residing in the school, it is difficult to overlook the fact that the seismic design is omitted. In other words, seismic reinforcement for the building is necessary.
As a part of this, Korean Patent Office Application No. 10-2010-0080538 and Korean Patent Application No. 10-2011-0011485 disclose techniques for reinforcing a structure that is lacking in earthquake-resistant design.
However, in the case of the prior art including the above documents, it is reported that the structural restraint is difficult to apply because of the difficulty in reinforcing construction for earthquake proofing. Therefore, Research and development on the structure is necessary.

With reference to these drawings, the structure of the seismic strengthening structure according to the present embodiment has a compact structure, so that it is possible to easily carry out the reinforcement construction for earthquake proofing, which is advantageous for practical application, And may include a structure body 110 and a plurality of anti-seizing reinforcement units 120 for seismically reinforcing the structure body 110.
The earthquake-proof reinforcement structure of the building according to the present embodiment can be applied to, for example, a school building which is not designed for earthquake-resistant design. Particularly, since the present embodiment has a simple and compact structure, . Therefore, it is sufficient to efficiently prepare for vibration and earthquake.
First, the structure body 110 forms the outer shape of the structure in which the reinforcing space portion 111 is formed. These structures can be subjected to seismic reinforcement.
Briefly, the structure body 110 includes a lower base 110a and an upper base 110b and a connection 110c between the lower base 110a and the upper base 110b ) Can be formed.
A reinforcing space portion 111 may be formed between the lower base 110a, the upper base 110b and the connecting portion 110c. A plurality of reinforcing reinforcing units 120 may be installed.

The second reinforcing flange 123 is disposed at the other end of the reinforcing frame 121 in the reinforcing frame 121 so as to form an outer periphery of the penetrating portion 120a.
The second reinforcement flange 123 may also be partially welded or anchored like the first reinforcement flange 122. At this time, since the first reinforcing flange 122 and the second reinforcing flange 123 protrude from both sides of the reinforcing frame 121, the reinforcing function can be doubled.
The structure in which the first reinforcing flange 122 and the second reinforcing flange 123 are provided on the reinforcing frame 121 as described in this embodiment can exert an excellent effect in strengthening the strength. In other words, it is possible to prevent the reinforcing frame 121 from being easily bent, thereby providing an excellent reinforcing effect.

That is, the H-shaped steel can be used as it is, or the existing H-shaped steel can be modified and used. The reinforcing frame 121, the first reinforcing flange 122, and the second reinforcing flange 123 can be welded to each other.
The vibration-damping reinforcement unit 120 having such a structure is further provided with a vibration dampening portion 124 for absorbing vibration.
In the present embodiment, the vibration damping portion 124 may be applied as a vibration damper hole, and may be formed to penetrate through the reinforcing frame 121.
In the present embodiment, one vibration damper through hole is formed, but a plurality of vibration damper through holes may be formed on the reinforcement frame 121 to provide a function as the vibration dampener 124.
The end reinforcement and coupling plate 130 is further connected to each of the vibration reinforcement units 120 applied to the present embodiment.
The end reinforcement and coupling plates 130 are respectively coupled to the end portions of the reinforcement frame 121. The end reinforcement and engagement plates 130 are used as a place to be coupled with the neighboring reinforcement frame 121 in addition to reinforcing the end portions of the reinforcement frame 121. That is, the end reinforcing and coupling plate 130 may be used as a place to be coupled with the neighboring reinforcing frame 121 in addition to reinforcing the end portion of the reinforcing frame 121 by reducing warpage of the end portion.
At least one through hole 131 may be formed in the plate 130 for end reinforcement and engagement and may be coupled with the neighboring reinforcing frame 121 through the through hole 131.
The area of the end reinforcing and connecting plate 130 is formed to be the same as the area formed by connecting the outer frame of the reinforcing frame 121, the first reinforcing flange 122 and the second reinforcing flange 123 .
The structural reinforcement unit 120 as described above is disposed in the reinforcement space 111 in the structure body 110 and is joined in a state as shown in Fig. 1, so that the structure body 110 can be reinforced. It is possible to prevent the structure body 110 from being damaged even if vibration or earthquake occurs.
According to this embodiment having such a structure and action, it is possible to easily carry out the reinforcing construction for the earthquake-proof due to the compact structure, which is advantageous for practical application. Accordingly, it is possible to effectively prepare for vibration and earthquake, Can be minimized.
