DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

Prior to describing the construction method of the partition wall having the seismic load absorbing function according to the present invention, a seismic load absorbing device for providing the seismic load absorbing function to the partition wall will be described.

1 is an exploded perspective view showing a unit modular seismic load absorbing device installed in a ramen frame according to the present invention, Figure 2 is a perspective view.

1 to 2, the unit modular seismic load absorbing apparatus 10 according to the present invention is a corrugated web 100 formed of a corrugated steel sheet and a support member respectively formed on the upper and lower ends of the corrugated web 100. It consists of 200. The height of the corrugated web 100 may be variously configured to match the overall height of the lower surface of the beam and the upper surface of the slab where the partition wall is to be constructed. The shape of the overall cross section is similar to the cross section of the H-shaped steel, but the web was formed in a wave shape, the support member 200 is a structure consisting of H-shaped steel.

Corrugated web 100 is composed of corrugated steel sheet (corrugated steel) to prevent relative displacement (slip) at the interface between the corrugated web 100 and wall concrete by mechanical engagement with concrete, so that they are synthesized integrally. Improved resistance to buckling and torsion. As shown in FIG. 3, the corrugated web 100 may be made of, for example, cold-rolling, and the shape of the valley is not limited to a rounded shape (a), a curved square (b), and the like. It may be configured as.

The impact damping unit 110 has a shape in which the corrugated web 100 has a central portion of both ends drawn inward. This is because the waveform web 100 absorbs the seismic load while plastically deforming like an accordion when the seismic load is applied. In the present invention, since the waveform web 100 is formed almost as long as the height of the space between the beam and the slab. In the structure in which a plurality of unit modular seismic load absorbing devices 10 are installed in parallel, the displacement amount of the waveform web 100 decreases toward the side, so that the space is called a shock attenuation part 110 to increase the displacement amount to support the load. To dampen the amount of impact at time.

The impact damping unit 110 is configured in a shape in which both ends of the corrugated web 100 are inserted, but the ends of the adjacent corrugated web 100 are not in contact with each other by cutting, bending, or the like, and the impact damping unit 110 The space part is formed by this.

The support member 200 is composed of a web 12 connecting the upper flange 11, the lower flange 13, and the upper and lower flanges in the widthwise center in the shape of a general H-shaped steel, and additionally the upper and lower flanges 11 and 13. An end plate 14 is connected to connect both ends of the side wall. The end plate 14 is configured to couple the side of each adjacent unit modular seismic load absorber 10 when a plurality of unit modular seismic load absorbers 10 are arranged in parallel in a position where the partition wall is to be constructed. .

The end plates 14 may be joined by various known methods, such as welding each other, or may be bolted through the fastening holes 141 through the fastening holes 141.

The support member 200 has a predetermined thickness and width, and may be made of various materials, but it is advantageous to combine the other members with various steel materials. The upper flange 11 may be formed by drilling a plurality of anchor bolt insertion holes for fixing the upper flange 11 at regular intervals along the longitudinal direction. The upper flange 11 may be fixed to the lower surface of the beam by various methods well known in the art to be able to behave integrally with the beam during seismic load action, and as an example to the lower surface of the beam and the upper surface of the slab by an anchor bolt Can be fixed.

 The filler 15 is filled in the space surrounded by the upper flange 11 and the lower flange 13. Filler 15 wraps and constrains web 12. As the filler material 15, mortar or concrete may be used.

The support member 200 is fixed to the beam or slab so that the displacement will be concentrated in the corrugated web 100 when the external force is applied. However, when the strength of the wall concrete 80 is greater than that of the main structural member, the earthquake load action is applied. Since the load is concentrated on the main structural member when the earthquake load absorbing device according to the present invention may not operate effectively, the strength of the wall concrete 80 is configured to be lower than the strength of the main structural material.

In the following, a method of constructing the partition wall using the seismic load absorbing device constructed as described above will be described.

5 to 8 are front views sequentially showing a method of constructing a partition wall according to the present invention.

When the seismic load resistance system is added by the partition wall to the existing building after the construction of the frame is completed, the upper surface of the slab 40 between two adjacent columns 20 and 20 after removing the existing masonry and lightweight concrete partition wall. The unit modular earthquake load absorbing device 10 described above is installed on the lower surface of the beam 30, respectively. Since the method of installing the upper surface of the slab and the lower surface of the beams is the same as the method of fixing the support members 200, respectively, the method of installing the unit modular seismic load absorbing device 10 mainly on the lower surface of the beam 30 will be described below. An example will be described.

First, in order to install the unit modular seismic load absorber 10 at the position where the partition wall is to be constructed, as shown in FIG. 5, the unit modular seismic load absorber 10 is arranged in parallel, and the lower surface of the beam and the slab are Fixing the support members 200 and 200 of the unit modular seismic load absorbing device 10 on the upper surface.

First, the upper flange 11 of the support member 200 is fixed to the lower surface of the beam 30. The upper flange 11 can be fixed in a variety of ways known in the art that can be firmly fixed to the beam 30 so that it can be integrally behaved with the beam 30 when an earthquake load is applied. As an example, the anchor hole is drilled on the lower surface of the beam and the anchor bolt is inserted, and then the anchor bolt is fixed by filling the non-shrink mortar with the anchor hole, and the anchor bolt insertion hole is drilled in the upper flange 11, and then the anchor bolt is It can be fixed by passing through the anchor bolt insertion hole and fastening the nut. Thereafter, the corrugated web 100, which is made of corrugated steel sheet, is joined over the entire length of the lower flange 13 of the supporting member 200, and the upper surface of the corrugated web 100 is in the longitudinal direction of the lower flange 13. Position it in the center. The support member 100 fixed to the slab 40 is also coupled to the bottom surface of the corrugated web 100 in the same manner.

Unit modular seismic load absorbing device 10 composed of the corrugated web 100 and the support members 200 respectively configured on the upper and lower ends of the corrugated web 100 may be welded and assembled in the field, but before installation in the beam, By assembling and placing the partition wall at the site where it will be constructed, it can be fixed to shorten the construction process.

4 is a view showing a coupled state of the seismic load absorbing apparatus of the present invention, Figure 4a is a perspective view when the impact damping unit 110 is formed, Figure 4b is a case when the impact damping material 300 is configured It is a perspective view, and FIG. 4C is a front view of the said FIG. 4B.

Referring to FIG. 4, when the unit modular seismic load absorbing device 10 is disposed in parallel, the impact damping unit 110 configured to have the central portions of both ends of the corrugated web 100 drawn inward as shown in FIG. 4A. 4B and 4C, the impact damping material made of a material such as rubber, rubber foam, etc. of elastic material between the unit modular earthquake load absorbing device 10 and the unit modular earthquake load absorbing device 10. 300 may be configured, and when the impact damping material 300 is used, only the side cross-section of the corrugated web 100 may be configured, or both the side cross-section of the support member 1200 and the side cross-section of the corrugated web 100 may be used. It can also be configured.

This is because the waveform web 100 absorbs the seismic load while plastic deformation as the accordion during the seismic load action, in the present invention, the waveform web 100 is formed to a length almost equal to the height of the space between the beam and the slab, In a structure in which a plurality of unit modular seismic load absorbing devices 10 are installed in parallel, since the displacement amount of the corrugated web 100 decreases toward the side, an earthquake is formed by forming a space called an impact damping material 300 or an impact damping part 110. When a load is applied, a material capable of absorbing the horizontal displacement of the earthquake load absorbing device 10 is used together with a shock absorbing function to prevent the corrugated webs 100 of the unit modular seismic load absorbing device 10 from directly colliding with each other.

Next, as shown in FIG. 6, the filler 15 is filled in the space between the upper flange 11 and the lower flange 13 of the support member 200. The filler material 15 can be tightly filled in the space between the upper flange 11 and the lower flange 13 by any method known in the art, such as filling concrete in steel pipes.

Next, as shown in FIG. 7, after the filler 15 is sufficiently cured, the buffer plate 70 is disposed over the entire height between the slab 40 and the beam 30 on the pillar faces facing both pillars 20, respectively. Install. Accordingly, the buffer plate 70 is disposed between both ends of the pillars 20 and both ends of the unit modular seismic load absorber 10. The buffer plate 70 has a width corresponding to the thickness of the partition wall to be constructed and the thickness may be determined by the horizontal displacement of the earthquake load absorbing device 10. The buffer plate 70 is a material capable of absorbing the horizontal displacement of the earthquake load absorber 10 together with a shock absorbing function that prevents the pillar 20 and the earthquake load absorber 10 from directly colliding when the earthquake load is applied. Used. Various materials known in the art which perform this function can be used, for example rubber or rubber foam can be used.

Finally, as shown in FIG. 8, the wire mesh is placed in a space surrounded by the lower surface of the buffer plate 70 and the beam 30 and the upper surface of the slab 40, and the wall concrete 80 is poured.

As described in detail above, according to the present invention, an earthquake load absorbing device is installed at the top and the bottom of the partition wall, respectively, and the earthquake load absorbing device 10 has the strength of the filler material 15 of the pillars 20 and the beams 30. Since the seismic load is lower than the seismic load is concentrated in the seismic load absorber (10). Therefore, the wavy web 12 causes plastic deformation. That is, the seismic load absorber according to the present invention is similar to the displacement dependent energy dissipation device using the energy dissipation characteristics due to plastic deformation of the metal, so that the wave shaped web 12 is deformed like an accordion and absorbs the seismic load to the main structural member. This reduces the transmitted seismic loads. Therefore, it is possible to prevent damage to the main structural members due to the earthquake load, and after the earthquake, only the earthquake load absorbing device needs to be replaced, so maintenance is easy.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention . The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
