Description

Damping device with buckling prevention function {DAMPING DEVICE HAVING ANTI-BUCKLING FUNCTION}

The present invention relates to a vibration damping device having a buckling prevention function, and specifically, to a vibration damping device capable of preventing the buckling of the damper portion using a hinged buckling preventing portion and a box-type reinforcement.

It is common to apply a technique to respond to earthquakes on structures including various buildings. These technologies absorb seismic energy by concentrating damage on vibration control devices and seismic technologies that prevent collapse by absorbing seismic energy due to damage to the structure itself. Therefore, there are vibration suppression technology to reduce the shaking of the structure and prevent damage to the building, and seismic isolation technology to prevent the shaking of the ground caused by the earthquake from being directly transmitted to the building, and these are all included in the seismic technology in a broad sense.

Among these seismic technologies, a seismic isolation method using a vibration isolation device dissipates vibrational energy caused by earthquakes as thermal energy of a damper that is an energy dissipation device, and is known as an effective and economical earthquake-resistant reinforcement method by minimizing the location and number of earthquake-resistant reinforcements.

Therefore, there is a need for a vibration damping device capable of solving such problems.

1 to 4, the vibration damping device 1000 according to an embodiment of the present invention may include a damper part 100 and a buckling prevention part 200.

The damper part 100 is formed of a steel material, and a plurality of struts 110 may be formed in a vertical direction so as to be deformed laterally when an earthquake occurs.

Specifically, a plurality of struts 110 are spaced apart from the damper unit 100, and a slit (not shown) may be formed between the struts 110, resulting in an earthquake, resulting in horizontal load in the lateral direction. In this case, the damper unit 100 can absorb seismic energy while plastically deforming in the transverse direction. Here, the lateral direction may mean the longitudinal direction of the vibration damping device 1000 (or the left and right directions of the damper unit 100).

The damper part 100 may be formed using various steel materials such as carbon steel and stainless steel, and is formed in a shape of a rectangular plate as a whole, but is not limited thereto.

The damper part 100 may include a mounting part 120, connecting parts 130 and 140 and a deforming part 150.

The mounting unit 120 is a structure for coupling the damper unit 100 to the structure, and may be formed at upper and lower ends of the damper unit 100. For example, the mounting portion 120 may be composed of an upper mounting portion and a lower mounting portion, the upper mounting portion may be mounted on the upper fixing frame P1, and the lower mounting portion may be mounted on the lower fixing frame P2. To this end, a plurality of damper connection holes 122 may be formed through the mounting portion 120 and may be mounted on a pillar by a bolt or the like.

The connecting portions 130 and 140 are hinged coupling portions of the buckling preventing portion 200 (in particular, the buckling preventing plate 210 ), and may be formed between at least some struts 110. For example, the connecting portions 130 and 140 may be formed of a first connecting portion 130 and a second connecting portion 140 spaced apart at a predetermined interval in the vertical direction, and the first connecting portion 130 and the second connecting portion Struts 110 may be disposed on the left and right sides of the 140.

At this time, since the first connection unit 130 and the second connection unit 140 are spaced apart in the vertical direction, the deformation unit 150 may be formed through a space between the first connection unit 130 and the second connection unit 140. have. In spite of the coupling of the buckling preventing plate 210 by the deformable portion 150, only the longitudinal deformation of the damper portion 100 is limited, and the lateral deflection may be configured not to be limited.

Specifically, when an earthquake occurs, the longitudinal deformation of the strut 110 is limited by the buckling preventing plate 210 disposed on at least one surface of the damper part 100, but the first connection part 130 and the second connection part 140 may be configured to effectively transmit the lateral force caused by the earthquake to the strut 110 while being shifted from each other in the lateral direction. Through this, even if the buckling preventing plate 210 is installed, it is possible to prevent the natural function of the damper unit 100 from absorbing seismic energy due to the lateral deformation of the strut 110.

In addition, hinge connecting holes 132 and 142 for hinge coupling with the buckling preventing portion 200 may be formed on the first connecting portion 130 and the second connecting portion 140, respectively.

In one embodiment, the damper unit 100 of the vibration damping device 1000 may be configured in plural. For example, the damper part 100 may include a first damper part 100a and a second damper part 100b spaced apart in the front-rear direction. At this time, the first damper part 100a and the second damper part 100b are formed in the same shape, and the mounting part 120, the first connection part 130, the second connection part, and the deformation part 150 described above are the same. It can be formed, the structure may be coupled between the first damper portion (100a) and the second damper portion (100b). However, this is an example, and the number, shape, and coupling structure of the damper unit 100 constituting the vibration damping device 1000 may be variously modified.

The buckling prevention unit 200 may be coupled to at least a portion of the front and rear surfaces of the damper unit 100 to prevent out-of-plane buckling from occurring in the damper unit 100. At this time, the buckling preventing part 200 is hinged to be rotatable with respect to the damper part 100 to limit the longitudinal deformation of the damper part 100, and to allow the lateral deformation, thereby out of the surface of the damper part 100 Buckling can be prevented. Here, the longitudinal direction refers to a direction perpendicular to the transverse direction (that is, the longitudinal direction of the vibration isolator 1000), for example, may indicate the front-rear direction of the damper unit 100, and the longitudinal deformation is a strut It may mean that the 110 moves while being bent in a direction perpendicular to the transverse direction.

The buckling prevention part 200 may include a buckling prevention plate 210 and hinge coupling parts 220 and 230.

The buckling prevention plate 210 is disposed on one surface of the damper part 100, and is coupled so that the strut 110 overlaps at least a part, thereby supporting one surface of the damper part 100, thereby vertically deforming the damper part 100. Can be limited. That is, it is possible to limit the buckling of the strut 110 in the longitudinal direction (out-of-plane), and to serve to induce deformation in the transverse direction.

For example, the damper unit 100 may include two damper units 100 including a first damper unit 100a and a second damper unit 100b. In this case, the buckling preventing plate 210 is respectively coupled to the front surface of the first damper part 100a and the rear surface of the second damper part 100b, so that the front and second damper parts 100b of the first damper part 100a are respectively coupled. ).

In this case, the buckling prevention plate 210 may be implemented to be coupled to at least one of the front and rear surfaces of the damper unit 100.

The buckling prevention plate 210 may be hinged to be rotatable with respect to the damper portion 100. For example, the upper and lower ends of the buckling preventing plate 210 may be hinged to the first connecting portion 130 and the second connecting portion 140, respectively. To this end, the hinge inserting holes 212 corresponding to the hinge connecting holes 132 and 142 of the first connecting portion 130 and the second connecting portion 140 are formed at the upper and lower portions of the buckling prevention plate 210, hereinafter It can be hinged with the damper portion 100 by the hinge coupling portion 220, 230 described in.

The hinge coupling parts 220 and 230 are for hinge coupling the buckling preventing plate 210 to the damper part 100, and may include hinges 222 and 232 and hinge coupling pins 224 and 234.
