An earthquake load absorbing device and a method for reinforcing steel structures using the same.

Recently, due to a series of large earthquakes occurred at home and abroad, awareness about the damage of earthquake and necessity of seismic design is spreading. Especially, important earthquake damage such as museums, nuclear power plants, and large structures such as high-rise buildings, stadiums and bridges are accompanied by huge damage to life and property. In addition, since the remodeling of residential buildings is widely promoted, there is a growing interest in seismic strengthening methods of buildings constructed before the earthquake - resistant design standards are applied.

In general, steel structures have been widely used in infrastructure facilities and plants, and existing structures have been designed to meet the requirements of national design (earthquake) standards at the time. However, The seismic design criteria is judged to be the installation of reinforcement structures through the reinforcement design of existing facilities. Most of the braces are designed to receive tensile force and have a large slenderness ratio. When they receive compressive force, they cause elastic buckling, failing to function as a brace.

In addition to the seismic design, which is designed to resist the building's seismic resistance, the building is separated from the ground and the building's vibration cycle is moved away from the main period of the earthquake, Seismic Isolation and Seismic Control to Minimize the Damage of Buildings by Reducing Input Energy by Using Various Dampers to Minimize Life and Property Damage by Earthquake .

However, the existing partition wall simply serves to separate the seal and the seal, and even in the conventional vibration suppression apparatus installed therein, most of them are made of steel structures, so that the load-bearing performance is degraded due to corrosion and cross-sectional reduction.

As a background of the present invention, there is a patent registration No. 1026106 entitled " Lamination structure of damper damper frame and method of joining "(patent document 1).

In the background art, in the installation frame for installing the damping damper in the existing building, as shown in Figure 7, the anchor bolt 720 is inserted into a plurality of openings perforated on the surface 710 chipping the existing concrete, the chipping A base plate 730, which is supported on a surface and is fixed through a plurality of openings arranged in the center of the body, is formed between the chipping surface and both ends of the base plate, and has a predetermined space therebetween. A gap retaining material forming a gap, spaced apart from the base plate, the anchor bolt is passed through a plurality of openings formed in the body so as to correspond to the opening of the base plate, the vibration damper 800 and the brace connected to the vibration damper ( Damper frame 740 to which the 900 is connected, a fixing agent to be integrated between the chipping surface and the base plate, and the base plate And a filler material which is introduced into the space between the rate and the damper frame to integrate the damper damper frame.

However, the background art is not only complicated in the construction process because the damping damper is installed by chipping the existing concrete wall, but also has a problem that it is difficult to use when constructing or dividing the partition wall that divides the thread and the load-bearing performance by chipping. Falling, there is a problem that the load-resistant performance is deteriorated due to corrosion and cross-sectional reduction because most of the conventional vibration suppression apparatus installed thereon made of a steel structure.

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.

The unit modular earthquake load absorbing device capable of reinforcing load-bearing performance according to the present invention will be described.

1 is a perspective view showing a unit modular seismic load absorbing device installed in a steel frame structure according to the present invention, Figure 2 is a partial exploded perspective view of FIG.

1 to 2, the unit modular seismic load absorbing device 10 capable of reinforcing load-bearing performance according to the present invention is provided on the top and bottom of the web member 100 and the web member 100 formed of a corrugated steel sheet. Composed of the upper concrete 200 and the lower concrete 300 to be synthesized, synthesized by the fixing member 400 in the front and / or rear portion consisting of the web member 100, the upper concrete 200 and the lower concrete 300 The wood panel 500 is made to be fixed by simply supporting it without being completely coupled.

3 is a sectional view taken along the line A-A in Fig.

The web member 100 has a corrugated web 110, a spacing member 130 that is installed to protrude to a predetermined length on both sides of the upper and lower ends of the corrugated web 110, the plate-shaped coupled to the end of the spacing member 130 Plate 140 on the upper surface, the nut 150 is formed with one end coupled to the central portion of the outer surface of the plate 140, the gap retaining material 130, the plate 140 and the nut on the upper and lower ends of the corrugated web 110 150 is embedded, and the upper concrete 200 and the lower concrete 300 are formed to be combined so that the other end of the nut 150 is exposed.

Corrugated web 110 is composed of a corrugated steel sheet (corrugated steel sheet) to improve the resistance to buckling and torsion, and when the seismic load acts, the corrugated web 110 is plastically deformed like an accordion to absorb the seismic load.

The shock attenuation portion 111 is configured in a shape in which both ends of the corrugated web 110 are retracted, and is formed by cutting, bending, or the like. This is because when the corrugated web 110 is plastically deformed like an accordion, the seismic load absorbs the seismic load. In the present invention, since the corrugated web 110 is formed almost as long as the space height between the beam and the slab, In the structure in which the unit modular seismic load absorbing device 10 is installed in parallel, since the displacement amount of the corrugated web 110 decreases toward the side, the impact damping part 111 is formed, and the corrugated web 110 is subjected to the seismic lateral force. By plastic deformation, the buffer space 112 is resisted to some extent, and the displacement amount is increased so that the impact amount can be attenuated when the support load is applied.

As shown in FIG. 4, the corrugated web 110 may be made of, for example, cold-rolling, and the shape of the bone is not limited to a rounded shape (a), a curved square (b), and the like. It may be configured as.

The gap maintaining member 130 is installed to protrude to a predetermined length on both side surfaces of the upper and lower ends of the corrugated web 110. The gap retaining member 130 may be configured in various forms such as steel wire, rebar, angle, and the like. In addition, the spacing member 130 may be provided to penetrate the corrugated web 110 or may be configured to be coupled at both ends of the corrugated web 110. At this time, the end of the outer side of the spacer 130 must be configured to be in the same position. This is to position the plate 140 at regular intervals from the center of the corrugated web 110 when the plate 140 is coupled to the spacing member 130 to be described later.

The plate 140 is coupled to the outer end of the spacer 130 and has a long plate shape in the longitudinal direction of the corrugated web 110.

When the gap retaining material 130 and the plate 140 are synthesized on the upper and lower surfaces of the upper concrete 200 and the lower concrete 300 and the web member 100, respectively, also serves as a shear connector.

In addition, the plate 140 may be separately drilled to form a through hole, and the plate 140 may be synthesized so that the concrete is continuous without being cut off.

The nut 150 is formed by coupling one end to a central portion of the outer surface of the plate 140. That is, one end is coupled to the plate 140 and the other end is exposed to the outside after synthesis with the upper concrete 200 and the lower concrete 300. That is, the shape of the nuts embedded in the upper concrete 200 and the lower concrete 300.

The upper concrete 200 and the lower concrete 300 are synthesized on the upper and lower ends of the web member 100, respectively, the upper and lower spacers 130, the plate 140 and the nut (top and bottom of the corrugated web 110) 150 is embedded, and the other end of the nut 150 is synthesized to be exposed.

The existing partition wall simply serves to separate the seal and the seal, and the conventional vibration suppression device installed therein is mostly made of steel structures, and thus has a problem in that the load carrying capacity is degraded due to corrosion and cross-sectional reduction.

Therefore, the present invention synthesizes the upper concrete 200 and the lower concrete 300 formed of concrete on the upper and lower portions of the corrugated web 110 as described above to increase the load carrying performance.

At this time, one side of the upper concrete 200 and the lower concrete 300 is protruded to the outside to form a key 210, 310, the other side of the key groove formed a groove corresponding to the key (210, 310) When the plurality of unit modular earthquake load absorbing devices 10 are arranged in parallel at the position where the partition wall is to be constructed, the plurality of unit modular earthquake load absorbing devices 10 may be formed. It is configured to facilitate coupling and placement.

The keys 210 and 310 are not limited in particular shape and may be configured in various shapes, and the key grooves 220 and 320 are configured to have a shape corresponding to the keys 210 and 310.

Synthetic wood panel 500 may be coupled to the front portion or the rear portion of the upper concrete 200 and the lower concrete 300 is synthesized in the web member 100 and the upper and lower ends, or may be coupled to both the front portion and the rear portion. .

 Coupling of the composite wood panel 500 is coupled to the fixing member 400 to the nut 150 of the upper concrete 200 and the lower concrete 300 with a bolt 430, and fixing the upper and lower ends of the composite wood panel 500 In the form of sandwiching the member 400, the synthetic wood panel 500 is fixed so as to be supported simply without being completely coupled.

The fixing member 400 is made of a plate-shaped plate as a whole, the upper portion is made of a coupling portion 410 is formed through the coupling hole 411, the lower portion is bent from the coupling portion 410 protrudes outwards in equilibrium It is composed of a support portion 420 formed in the shape. That is, the upper portion is formed in a long plate shape, but the upper portion is made of a coupling portion 410, the lower portion of the support portion 420, the support portion 420 has a shape that protrudes further to the outside.

When the coupling part 410 of the fixing member 400 is fixedly coupled to the nut 150 exposed to the upper concrete 200 and the lower concrete 300, the support part 420 protrudes outward and the synthetic wood panel 500 ) May be inserted into the support 420 to be fixed.

That is, the fixing member 400 is fixed to the upper concrete 200 and the lower concrete 300 serves to simply press the synthetic wood panel 500.

As such, the simple support of the composite wood panel 500 without being completely coupled to the upper concrete 200 and the lower concrete 300 is that the composite wood panel 500 rotates every sheet when the earthquake displacement occurs, thereby interlayering up to 1 / 100rad. By following the deformation angle, the displacement tracking performance is improved to improve the vibration damping performance.

Fig. 5 is a view showing a combined state of the seismic load absorbing device of the present invention, Fig. 5A is a perspective view, and Fig. 5B is a front view.

As shown in FIG. 5, in a structure in which a plurality of unit modular seismic load absorbing devices 10 are installed in parallel, both ends of the corrugated webs 110 and 110 do not contact each other, and the shock attenuation portions 111 and 111 are not in contact with each other. ) Meet with each other to form a space portion called the buffer space 112.

Since the displacement amount of the corrugated web 110 decreases toward the side when the earthquake load is generated in the state where a plurality of unit modular seismic load absorbers 10 are installed, the corrugated web 110 is plastically deformed by the seismic lateral force, and the buffer space portion Reference numeral 112 denotes a resistance to which the displacement is increased so that the impact amount can be attenuated when the supporting load is applied.

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

6 is a front view showing a method of reinforcing a steel structure using a unit modular earthquake-absorbing apparatus according to the present invention in order.

The unit modular earthquake load absorber 10 is pre-fabricated (a).

The unit modular seismic load absorbing device 10 can be manufactured according to various embodiments described above.

The unit modular earthquake load absorbing device 10 except for the composite wood panel 500 may be manufactured to facilitate a construction in which the unit modular earthquake load absorbing device 10 is later arranged and fixed in parallel.

The unit modular seismic load absorbing device 10 may be assembled by welding in the field, but the assembly process may be shortened by fixing and arranging it in a position to be installed in the site before installing it in the beam.

Then, as shown in FIG. 6A, when a seismic load resistance system is added to the existing building by the partition wall, the existing masonry and lightweight concrete partition walls are removed. In the case of the new building, A space made up of the steel column 20 and the beam 30 is formed.

Subsequently, the unit modular seismic load absorbing device 10 is disposed between the two adjacent pillars 20 and 20 and the upper and lower beams 30 and 30, respectively, on the upper and lower beams 30 and 30, respectively. ) And install the bottom concrete 300 in combination.

First, the unit modular seismic load absorber 10 is installed in a position to be constructed as shown in FIG. 6B, and the unit modular seismic load absorber 10 is disposed in parallel, and the upper and lower beams 30 and 30 respectively. The upper concrete 200 and the lower concrete 300 are installed by combining in a variety of known methods.

The shock attenuation portions 111 of the unit modular seismic load absorbing device 10 are disposed in parallel so that the buffer space portion 112 is formed in contact with each other.

Side coupling of the unit modular seismic load absorbing device (10) (10) can be combined by placing the non-contraction mortar between the side coupling portion of the adjacent upper concrete (200), 200 and lower concrete (300) (300). .

Referring to FIG. 5B, when the unit modular seismic load absorber 10 is disposed in parallel, an impact damping material including high damping rubber between the unit modular seismic load absorber 10 and the unit modular seismic load absorber 10 ( 40 may be configured, and in the case of using the impact damping material 40, the side cross-section of the upper concrete 200 and the lower concrete 300 or the corrugated web 110 may be configured only on the side cross-section of the corrugated web 110. It can also be configured in both side cross-sections.

The impact damping material 40 is interposed in the buffer space 112, respectively. The impact damping material 40 is a plate shape, the height of which is equal to the height of the height of the buffer space 112 or the sum of the heights of the side cross-sections of the upper concrete 200 and the lower concrete 300 and the side cross-sections of the corrugated web 110. Can be configured.

Therefore, when the seismic web 110 is subjected to seismic load while the corrugated web 110 undergoes plastic deformation, such as an accordion, when the seismic load is applied, the impact damping member 40 performs energy with viscoelastic resistance and deformation between the unit modular seismic load absorbers 10. Absorb. The shock attenuator 40 may be any high attenuating rubber known in the art and is generally made by adding additives such as fillers, vulcanizing agents, anti-aging agents and plasticizers to natural rubber and / or carbon black, And a vulcanization process to apply pressure. The elasticity of the high-damping rubber can be adjusted according to the proportion of the additive, and the energy-dissipating ability depends on the elasticity. The impact damping member 40 may be secured by using an adhesive or an additional convex or convex shape in addition to the contact surface with the impact damping portion 111 to secure the fixing force at the installation position.

When the earthquake web 110 acts as the accordion plastic deformation during the seismic load action, the seismic load is absorbed. In the structure in which a plurality of unit modular seismic load absorbers 10 are installed in parallel as shown in the present invention, the wave shaped web 110 Since the displacement amount of the lower side toward the side, the shock damping material 40 or the shock attenuation portion 111 constitutes a space portion, the earthquake web 110 of the unit modular earthquake load absorbing device 10 when the earthquake load is applied directly A material capable of absorbing the horizontal displacement of the earthquake load absorbing device 10 is used with a shock absorbing function to prevent it.

When the unit modular seismic load absorbing device 10 is arranged in parallel, the buffer plate 70 may be installed over the entire height of the column surface facing both pillars 20.

A buffer plate (70) is installed over the entire height on the column surface facing the pillars (20) on both sides. 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 is made of a material capable of absorbing the horizontal displacement of the seismic load absorbing device 10, as well as a buffer function for preventing the column 20 from directly colliding with the seismic load absorbing device 10 when an earthquake load is applied do. Various materials known in the art for performing this function can be used, for example, rubber or rubber foam can be used, and the buffer plate 70 can be formed of the same high damping rubber as the impact damping material 40 above. have.

Finally, as shown in Figure 6c, a plurality of synthetic wood panel 500 is installed in the front surface of the space consisting of steel pillars 20, 20 and beams 30, 30 (c).

At this time, the angle 51 is fixed to the center of the upper and lower ends of the synthetic wood panel 500 and the angle 51 is installed to be coupled to the flange of the upper and lower beams 30,30. The angle 51 may be an angle of various shapes such as an L-shaped clip angle.

As such, the upper and lower ends of the composite wood panel 500 are pin-bonded with bolts, respectively, so that when the earthquake displacement occurs, the composite wood panel 500 rotates for each sheet to follow the interlaminar deformation angle up to 1 / 100rad. It is to improve the vibration damping performance.

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 unit modular earthquake load absorbing device 10 has a waveform lower than the strength of the column 20 and the beam 30. The web 110 induces plastic deformation so that the seismic load is concentrated in the seismic load absorber 10. 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 waveform web 200 is deformed like an accordion and absorbs the seismic load to the main structural member. This reduces the transmitted seismic loads. Therefore, while preventing damage to the main structural member due to the earthquake load, the load-bearing performance is improved by the upper concrete 200 and the lower concrete 300 configured on the upper and lower portions of the corrugated web 110.

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.
