Description

[0001] The present invention relates to a three-point toggle type vibration damping damper device,

The present invention relates to a vibration damper device, and more particularly, to a damper damper device having damping elements arranged in a circumferential direction and having a plurality of damping elements installed in a pillar and a brace in a brace direction to dissipate vibration energy, To a three-point toggle type highly integrated damper damper device.

The vibration damper is composed of a steel damper (metal damper) which is made to dissipate the energy by using the yielding mechanism of the steel, a friction damper which uses the friction mechanism as the energy dissipating device, and a viscous material which shows the speed dependence, Viscous dampers that dissipate, viscoelastic dampers that dissipate the energy input to the system using elastic materials, which exhibit both speed dependence and displacement dependency. With the start of steel dampers, friction dampers, and viscous dampers, vibration dampers have gained widespread acceptance as a way to improve seismic performance of seismic and structural engineering systems for the past 20 years. This trend is increasing.

However, despite the excellent seismic performance of the damping structure using the damping system and various applications, there is a very limited use of the damping system in Korea, which is classified as the small damping area. However, recently, there has been increasing concern about the indirect damage caused by the earthquake in Japan and the uncertainty about the earthquake - damaged area has been increased.

However, the steel damper has a disadvantage that the damper must be replaced due to residual deformation due to plastic deformation. In the case of the friction damper, friction force is also important. However, wear of friction material and expansion of the base material due to frictional heat It is disadvantageous to eliminate the uncertainty of frictional force due to cold welding which may occur when the frictional behavior due to various complicated frictional phenomena and the frictional behavior in the state where vertical periodic pressure is applied do not occur during the period of the steel period. In addition, since the steel damper and the friction damper are subjected to residual deformation after the operation, there is an additional disadvantage that they can not be used for wind control because they are not compatible with the wind design concept which is designed for elastic design. It is a disadvantage that viscous damper is more expensive than steel damper or friction damper in addition to continuous maintenance.

Recently, it is international trend to examine the statistical safety factor for the maximum level earthquake larger than the design earthquake in order to minimize the economic damage due to the earthquake due to the rapid urbanization, population concentration, . In consideration of economical efficiency, it is difficult to simultaneously control the vibration of the structure due to wind and earthquake by installing the above-mentioned individual damper on the structure, and it becomes more difficult to secure an appropriate safety factor for the maximum level earthquake which is an international trend.

A technology to be a background of the present invention is Korean Patent Registration No. 10-0977041, which is referred to as " shaking hatch for building ". This is a damping hunting for a building installed at a beam-column connection part or a wall-bottom plate joint part of a building, and is a horizontal plate fixed to a beam or a bottom plate; A vertical plate fixed to the column or the wall; A vibration damping unit having one side hinged to the horizontal plate and the vertical plate to absorb vibration and having at least one lead pivot; A first link hinged to the horizontal plate at one end via a hinge portion and coupled at the other end to the other side of the vibration damping unit; And a second link whose one end is hinged to the vertical plate via the hinge portion and the other end is coupled to the other side of the vibration isolation unit, so that energy (seismic force or the like) input to the building by the plurality of links and the vibration isolation unit is efficiently So that the deformation of the building can be prevented as much as possible.

However, the background art has a disadvantage in that it is difficult to dissipate a large strain energy of the structure because the amplitude is small.

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.

As shown in Fig. 1, the three-point toggle type highly integrated damper damper device according to the present embodiment includes a caisson toggle type vibration damper 10 having one end hingedly connected to a corner where the beam 1 and the pillar 2 meet, A first brace 100a hinged to the beam 1 and hinged to the other end of the seesaw toggle type vibration damper 10 at one end and a brace 100a hinged at one end to the column 2 side, And a second brace 100b hinged to the other end of the damper 10.

The first brace 100a and the second brace 100b have the same structure. In this embodiment, the hinge connection plates 101 and 101 are provided at the distal end of the cylindrical body, but the present invention is not limited thereto .

Accordingly, the three-point toggle type highly vibration damper device has a structure in which the caisson toggle type vibration damper 10, the first brace 100a, and the second brace 100b are connected in a substantially T-shape as a whole.

As shown in FIGS. 2 to 5B, the damper damper 10 is provided with a pair of first and second link supporting bodies 20, 30 facing each other. The first and second link supporting bodies 20, 30 are disposed facing each other in a straight line X at regular intervals.

The first link support body 20 includes a first end connector 21 and a first spacing member 22 having a thermally cross section 221 and connected to the first end connector 21, 22 having a L-shaped cross-section mounted on the right-angled face of the cross-shaped cross-section 221 of each of the link members 23.

The first end connector 21 is formed of a pair of plates having a connection hole 21a. The first end connector 21 is connected to the first spacing member 22 through engagement of the bolt B1 and the nut N1. In the present invention, the first end connector 21 is not limited to such a plate-like structure. The thickness of the cross-shaped cross section 221 in the first spacing member 22 may be equal to or slightly greater than the thickness of the first link 40 to be described later. Since the link connecting member 23 has an L-shaped cross section, it can be made of an L-shaped steel. At this time, one end of the link connecting member 23 is connected to the first spacing member 22 through a plurality of bolts B2 and a nut N2.

The second link supporting body 30 comprises a second spacing member 32 having a second end fitting 31 and a cross-shaped cross section 321 and connected to the second end fitting 31. The second end connector 31 is formed of a pair of plates having a connection hole 31a. The second end connector 31 is connected to the second spacing member 32 through engagement of the bolt B3 and the nut N3. In the present invention, the second end connector 31 is not limited to such a plate-like structure.

A plurality of pairs of first and second links 40 and 50 are disposed between the first link supporting body 20 and the second link supporting body 30 at regular intervals in the circumferential direction. Each of the first link 40 and the second link 50 of each pair is overlapped at one end thereof and hinged to each other through the tightening bolt 60. At this time, the other end of the first link 40 is connected to the first link connecting member 23 and the other end of the second link 50 is hingedly connected to the second spacing member 32 through bolts and nuts. At this time, each pair of the first link 40 and the second link 50 has a variable angle? This variable angle (?) Is initially set smaller than 180 ° and larger than 45 °. In the present embodiment, the second links 50 are formed as a pair, but they may be formed as one body.

The tightening bolts 60 are respectively provided at the hinge portions where the first link 40 and the second link 50 are connected to each other so as to adjust the surface pressure applied to the damping element 70 by the tightening force with the nut 62 .

A damping element (70) is inserted into the tightening bolt (60). In this embodiment, the damping element 70 is disposed between the first link 40 and the second link 50. In the present embodiment, the second links 50 are formed as a pair, and two damping elements 70 are installed in one tightening bolt 60. Therefore, in this embodiment, the first link 40 and the second link 50 are installed at four intervals in the circumferential direction at intervals of 90 degrees, so that all eight damping elements 70 are installed.

The damping element 70 can be, for example, a high-damping rubber of a plate-like shape having a high elastic stiffness and a large energy dissipating capacity. Highly damped rubbers may be individually manufactured and installed or may be injected and installed in a mold. The damping element 70 may, for example, be constituted by a plate-shaped friction pad. The friction pad is made of an aluminum composite material in which ceramic particles are dispersed in aluminum or an aluminum alloy, a semi-metalic friction material using a carbon-carbon composite material, a metal fiber (steel fiber), a metal fiber, A non-steel friction material using only organic fiber and inorganic fiber without using metal fiber at all, and the like. 5A and FIG. 5B, the damping element 70 may be constructed by arranging a plurality of friction pads 72 in the circumferential direction on the surface of the disk 71.

The operation of the three-point toggle type highly integrated damper damper device constructed as described above will be described.

1 to 5B, the damper damper 10 is configured such that the first link 40 and the second link 50 vary in the direction of the load applied to the first and second end connectors 21 and 31, And the vibration is performed while the angle? Is decreased or increased. At this time, the first brace 100a and the second brace 100b cooperate with each other along the second end connector 31 to assist the vibration damping function of the vibration damper 10. [

4, the first link supporting body 20 and the second link supporting body 30 move in a direction close to each other when a compressive load acts on the first and second end connectors 21 and 31 in the direction of the arrow C, In this process, when one damping element 70 is viewed, different shear forces act on each other. As a result, the variable angle [theta] of the first link 40 and the second link 50 becomes small. Therefore, when the damping element 70 is made of high-damping rubber, elastic deformation occurs and the vibration energy is absorbed by the resistance of the shear deformation generated in the process.

Also, when a tensile load acts on the first and second end connectors 21 and 31 in the direction of arrow T, the first link supporting body 20 and the second link supporting body 30 move in directions different from each other, A single damping element 70 acts on the damping element 70 in the same direction. As a result, the variable angle [theta] of the first link 40 and the second link 50 is increased. Therefore, when the damping element 70 is made of high-damping rubber, elastic deformation occurs and the vibration energy is absorbed by the resistance of the shear deformation generated in the process.

Here, irrespective of the direction in which the first and second end connectors 21 and 31 act, the damping element 70 dissipates the seismic load as frictional energy when it is a friction pad.

The vibration damping damper 10 acting in this way has a damping element 70 which is arranged in the circumferential direction and is concentrated into a plurality of damping dampers 10, so that the energy dissipation capacity is increased. The amplitude of the amplitude can be increased by using the variable angle of the first link 40 and the second link 50.

Although the first link 40 and the second link 50 are arranged at intervals of 90 seconds in the present invention, the shape, structure, and size of the first and second link supporting bodies 20 and 30 are changed And may be installed at an angle smaller than the angle. The second link 50 may be formed on the side of the first link supporting body 20 and the first link 40 on the second link supporting body 30 side.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the above teachings. will be. The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
