Description
More particularly, the present invention relates to a vibration damping device that can dissipate vibrational energy due to wind loads or earthquake loads, and more particularly, to a vibration damping device having a plurality of connection rotation shafts, And the energy dissipation in the direction of the multi-axis can be performed.
Vibration control refers to the control of vibration caused by wind or earthquake in a building, and the structure with a special device or mechanism, that is, a vibration suppression device, is called a vibration suppression structure for vibration control. The purpose of vibration damping is to improve the safety and habitability of the structure by dissipating vibration energy input to the structure by wind or earthquake by installing a vibration isolation device.
As a vibration suppression method, there is an active control that reduces the vibration of the structure by applying the control force corresponding to the vibration of the structure from inside or outside of the structure and having the function of sensing the vibration of the structure and the vibration of the structure accordingly. There is a passive control that controls the dynamic response of the building by installing an additional energy dissipation device to improve the damping performance of the structure.
Passive type vibration suppression devices can be classified into mass vibration type and energy dissipation type. The former is mainly installed at the top of the building, mainly for the purpose of increasing the residence of the wind. The latter is mainly installed in each floor to increase the safety of the earthquake and the residence of the wind.
The energy dissipative type vibration damper can be divided into a displacement dependent type and a speed dependent type. The displacement dependent type device utilizes the energy dissipation characteristic due to the frictional force between the materials or the plastic deformation of the metal. The speed dependent type is a case where the viscous material, The energy dissipated by generating heat and dissipating the vibration energy has a characteristic that the energy dissipated increases in proportion to the speed.
Hydraulic dampers, which are a kind of speed dependent vibration damping devices, have excellent seismic performance compared with steel dampers and are mainly used in Japan where heavy earthquakes occur nationwide. However, since such a hydraulic damper is expensive, it is unnecessarily excessive in the country where the occurrence frequency of the earthquake is low and the strength of the earthquake is not high. On the other hand, the steel damper has a somewhat lower seismic performance than the hydraulic damper, but the steel damper is used for reinforcement of the steel structure because the construction cost is low.
As a background of the present invention, there is a patent document 10-1070043 'Column-shaped damper for improving seismic performance of a building' (Patent Document 1). This patent devises columnar dampers not to cause spatial obstacles. In particular, we propose columnar dampers with micro and macro fibers added to cement paste or cement mortar to improve the seismic performance of buildings. The column-type damper proposed by this patent has superior capability of suppressing or delaying cracks under design load and additional load as compared with existing cement composite, and is excellent in permeability and durability and improved energy dissipation and damage control ability However, when compared with other materials, there are problems such as the limit of ductility of cement composites and the occurrence of non-environmentally friendly waste when the column type damper needs to be replaced after earthquake load.
DISCLOSURE OF THE INVENTION The present invention has been made in order to solve the problems of the above-mentioned prior arts, and it is an object of the present invention to provide a steel material which is economical and eco-friendly material, a high damping rubber which is excellent in energy dissipation capability, And to provide a vibration damping device using the vibration damping device.
Another object of the present invention is to provide a vibration damping device in which the vibration damping member itself has various connection rotation shafts and can be moved in various directions around the connection rotation axis.
Another object of the present invention is to provide a vibration damping device having a shape capable of coping with a displacement in multiple directions rather than one direction by one vibration damping device.
A multi-joint vibration damping device according to a preferred embodiment of the present invention is a multi-joint vibration damping device according to a preferred embodiment of the present invention, in which a bolt hole is drilled at both ends and a bolt hole is drilled, A viscoelastic member disposed at an interval between the elongated member and the overlapped member and joining the elongated member and the overlapped member, And a bolt member (40) having a diameter smaller than that of the hole and the overhead bolt hole and connecting the long bolt hole with the overhead bolt hole and the viscoelastic member.
At this time, the length member is formed of a quadrangular cross-sectional member having two pairs of joining surfaces, and the connection between the overlap member and the length member can be connected in order by changing the joining surfaces of the length members.
A multi-joint vibration damping device according to another embodiment of the present invention is a multi-joint vibration damping device according to another embodiment of the present invention, in which a bolt hole is drilled at one end thereof with two ends and a bolt hole is perforated, A steel material overhang member having a length of steel material embedded therein, a bolt hole formed at both ends thereof, and both ends of the bolt hole being perforated so as to correspond to the bolt hole of the elongated member, And a bolt member having a diameter smaller than that of the longitudinal member bolt hole and the overhang bolt hole and connecting the longitudinal member bolt hole and the overhang bolt hole and the viscoelastic member to connect the viscoelastic member and the overhang member, .
The multi-joint vibration damping device according to the present invention is advantageous in that the vibration damping member itself has various connection rotation axes and can behave in various directions around the connection rotation axis with respect to the unpredictable directionality and the continuous vibration of the horizontal load.

Unlike vertical loads such as fixed loads and working loads, wind loads and seismic loads can not predict their directionality, and dynamic loads continue to oscillate, so the behavior of the damping elements can not be expected in a certain direction. Therefore, the multi-joint vibration damping device according to the present invention is designed so that the vibration damping member itself has various connection rotation axes and can move in various directions about the connection rotation axis, against unpredictable directionality and continuous vibration of horizontal load.

The multi-joint vibration damping device according to the present invention is characterized in that the direction of displacement is not limited to a plane. That is, the joint between the members constituting the vibration suppression device does not correspond to one-directional displacement in a plan view but can be deformed into multiple axes, so that three-dimensional displacement behavior can be expected.
In general, the structural design for lateral loads is such that wind loads and seismic loads can not predict their directionality, so that a planar vibration device acting as a single axis is installed in various directions along the axial direction of the building according to the building shape.
The multi-joint vibration damping device according to the present invention is advantageous in that a single vibration damping device can be operated with multiple axes, so that it is not necessary to install a vibration damping device in various directions on a building plane.
In the above-described and illustrated examples, a rectangular steel pipe having a biaxial cross-section is used as the
The use of the multi-joint vibration suppression device in the form of a column can be installed in almost every position except for some parts which can not be installed on the architectural plan, so that the degree of freedom in the construction of the building plan can be maximized. It is preferable that the residential high-rise building is installed in a space that is not occupied by a room occupant, such as a part of a facility shaft through which the equipment vertically penetrates, or a veranda portion where an air conditioner outdoor unit is installed. When the columnar vibration isolation device is installed in such a space, no additional space loss occurs.
4 is a cross-sectional view of a multi-joint vibration damping device according to another embodiment of the present invention.
In the present embodiment, the multi-joint vibration damping device is manufactured in a non-columnar shape, instead of a columnar shape. As shown in FIG. 4, when the
As described above, the multi-joint vibration damping device according to the present invention can be applied in various forms such as a column, a beam, a brace, or a slit horizontally disposed on a shear wall and between the slits.
As described above, the multi-joint vibration damping device according to the present invention has an advantage in that the vibration damping member itself has various connection rotation axes and can act in various directions around the connection rotation axis, against unpredictable directionality and continuous vibration of horizontal load have.
Further, since the multi-joint vibration damping device according to the present invention can be freely moved with respect to a plurality of directions of horizontal displacement, there is no limitation on the directionality, so that it can correspond to multi-directional lateral loads, .
In addition, the use of the articulated vibration damping device according to the present invention can reduce the size of the cross-section of the main structural member of the structure by only paying a vertical load, thereby enabling economical design. Is simple and easy to manufacture and install. It can contribute to productivity improvement because it is cheap, and it has a merit of simple replacement when permanent deformation occurs in the vibration damper after occurrence of the earthquake load.
