Description

[0001] The present invention relates to a multi-joint damper and a wall-type vibration damper using the damper,

The present invention relates to a vibration damping device designed to dissipate vibration energy of a building due to wind load or earthquake, and more particularly to a vibration damping device which induces a clear and stable shear deformation of a high-damping rubber, The present invention relates to a multi-joint vibration damper and a wall vibration damper using the same.

Damping means that the structure is controlled by reducing the vibration of the structure by applying a control force corresponding to the vibration of the structure inside or outside the structure, or by changing the stiffness or damping of the structure. The structure should be able to withstand the wind and earthquake, which are the main vibration sources causing vibration. For the wind, the structure is treated in the elastic region by treating it as working load, so that the residual strain should not remain when the wind vibration source is extinguished. On the other hand, for the load with large vibration energy, Shall be designed in such a way that the life safety of the residents can be achieved, while permitting residual deformation as well as damage to the main structural members.

The seismic or damping structure can be considered as an effective way to improve the vibration control performance of the structure. Among them, the vibration suppression system dissipates the seismic energy introduced into the structure by the energy dissipation function by using a special mechanical device, thereby controlling the displacement by reducing the inertia force that may occur in the structure. Since the vibration suppression device should act to dissipate the energy due to the deformation, it is installed in a place where the displacement of the structure is largely generated, has a shape capable of amplifying the displacement, and is used for increasing the damping. The increase of damping reduces the displacement, velocity and acceleration response of the structure, so that it can be seen that not only the high - rise structure but also the low - rise structure can be sufficiently effective. Especially, in the high - rise structure,

As a background of the present invention, there is a Korean Patent Registration No. 10-1221498 (a damping device for reducing lateral vibration displacement due to earthquake load). A bar-shaped displacement transmission link including one end of the pair of horizontal plates coupled to a corner position where the first horizontal plate and the side wall meet, and the other end positioned on the opposite end of the one horizontal plate; A first beam formed at a position facing the first horizontal plate, a third beam formed at a position facing the second horizontal plate, and a third beam formed between the third beam and the first beam, A second nodal point formed at a position where the second beam and the third beam are connected to each other, a second nodal point formed at a position where the first beam and the second beam are connected, A third node formed at a position where the four beams are connected to each other, and a fourth node formed at a position where the fourth beam and the first beam are connected; A rotating joint fixed to the second horizontal plate and hinged to the second node of the displacement amplification link; And a transmission beam coupled to the body so that a transverse displacement is attenuated and hinged to one of a third node and a fourth beam of the displacement amplification link, the body being fixed to the second horizontal plate, And a first damper.

The above-described background technology can be applied to any position of a building, and can effectively damp lateral displacement acting on the entire building. However, the background art is not a method of inducing shear deformation, and it is difficult to secure a stable hysteresis behavior in a large deformation.

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 wall-mounted vibration damping device according to the present invention is constructed in a wall-mounted vibration damping mode in order to secure a vibration damping capacity corresponding to the layer stiffness and the layer yield strength of a building. That is, the wall-mounted vibration damping device has a structure of wall-mounted between the upper and lower slabs. At this time, the installation position of the wall-mounted vibration damping device becomes the information of each slab.

5 and 6, the upper frame 20 and the lower frame 20a are supported by bolts 17 via a round bar set for damper fixing 13, which is embedded in the beams 12 and 12a, Respectively. The damper fixing round bar set 13 is provided with a round bar fixing plate 131 and a plurality of bolt connecting rods 131 having one end fixed to the round bar fixing plate 131 and a screw hole 132a for bolt connection at the other end 132).

The multi-joint vibration damper 30 uses the viscoelastic characteristics of the high-damping rubber provided at the two joint portions.

The multi-joint vibration damper 30 of the present embodiment includes an intermediate steel plate 31, a pair of upper and lower connection frame steel plates 32 and 33, upper and lower high-damping rubbers 34 and 35, And a ball bearing 37 as shown in Fig.

The intermediate steel plate 31 has a rectangular plate-like shape having a constant thickness. The intermediate steel plate 31 has upper and lower slot holes 31a and 31b at two positions on the upper and lower sides, respectively. At this time, the upper slot hole 31a and the lower slot hole 31b are arranged symmetrically with respect to the center line of the intermediate steel plate 31. The upper slot hole 31a and the lower slot hole 31b have the same hole length. At this time, the hole length is designed so that the elastic deformation of the upper and lower high-damping rubbers 34 and 35 can occur. That is, the upper slot hole 31a and the lower slot hole 31b are designed not to cause a failure in the elastic deformation of the upper and lower high-damping rubbers 34 and 35 according to the lateral load during vibration suppression.

The pair of upper connection frame steel plates 32 and 32 are positioned above the middle steel plate 31 with the intermediate steel plate 31 interposed therebetween. The upper connection frame steel plates 32 and 32 are formed in a rectangular shape having an area smaller than that of the intermediate steel plate 31. The upper end of the upper connection frame steel plates 32 and 32 is positioned higher than the height of the upper end of the middle steel plate 31 for connection with the upper frame 20. [ The upper connection frame steel plates 32 and 32 are formed with shaft coupling holes 32a at the same height as the upper slot holes 31a. The diameter of the shaft engagement hole 32a is formed to be larger than the height of the upper slot hole 31a.

The pair of lower link frame steel plates 33 are positioned under the intermediate steel plate 31 with the intermediate steel plate 31 interposed therebetween. The lower connection frame steel plate 33 is formed in the same shape and size as the upper connection frame steel plates 32 and 32. The lower connection frame steel plate 33 has a shaft coupling hole 33a at the same height as the lower slot hole 31b. The diameter of the shaft coupling hole 33a is also formed larger than the height of the lower slot hole 31b.

The two upper damping rubbers 34 are bonded to each other between a pair of upper connection frame steel plates 32 and an intermediate steel plate 31. The two lower damping rubbers 35 are bonded to each other between the lower connection frame steel plate 33 and the intermediate steel plate 31. In the present embodiment, the upper and lower damping rubbers 34 and 35 have a rectangular shape smaller than that of the upper and lower connecting frame steel plates 32 and 33, but are not limited to this rectangular shape. The upper and lower damping rubbers 34 and 35 are each formed as a single unit, but they may be provided in a divided structure. The upper high damping rubber 34 is installed below the upper slot hole 31a and the lower high damping rubber 35 is located above the lower slot hole 31b.

The load transmission shaft 36 is slidably inserted into the upper slot hole 31a and the lower slot hole 31b, and both ends thereof are inserted into the shaft coupling hole 32a. The load transmission shaft 36 transmits a vertical load or a lateral load to the upper connection frame steel plate 32 and the lower connection frame steel plate 33 when an earthquake or a wind load is generated so that the upper and lower highly damping rubbers 34, ≪ / RTI > The outer diameter of the load transmission shaft 36 is smaller than the inner diameter of the upper and lower slot holes 31a and 31b. Therefore, the load transmission shaft 36 can move freely within the allowance zones on the inner surface side of the upper and lower slot holes 31a and 31b.

At this time, both ends of the load transmission shaft 36 are moved in the axial direction of the ball insertion hole 32a so that the load transmission shaft 36 rotates in the corresponding upper slot hole 31a or the lower slot hole 31b. And is preferably coupled to the bearing (37).

The nut 38 is screwed to the load transmission shaft 36 so that the load transmission shaft 36 is not separated from the ball bearing 37. [ Shear deformation occurs in the upper and lower high attenuation rubbers 34 and 35 due to the behavior of the upper and lower connecting frame steel plates 32 during vibration suppression and the load transmitting shaft 36 is supported on the inner ring of the ball bearing 37 In the state of being in contact with the inner surfaces of the upper and lower slot holes 31a and 31b, respectively.

As shown in FIG. 7, the wall type vibration damper constructed as described above can be continuously installed on each floor of a building by a wall. In this case, the building is multi-jointed by a wall-type vibration damper, and the damping is performed by dissipating energy due to the stable hysteretic behavior of the high-damping rubber (34, 35) Particularly, the wall vibration damping device is formed by coupling between the ball bearings 37 and the slot holes 31a and 31b so that unstable shear deformation does not occur as shown in FIG. 8 (A) but a stable shear deformation The vibration damping efficiency can be improved.

Further, by coupling the middle steel plate and the upper and lower connecting frame steel plates by the load-bearing shaft supported by the ball bearings coupled to the upper and lower connecting frame steel plates, the wall type vibration damper can support not only the horizontal load but also the vertical load, When the interlaminar deformation occurs, the middle steel plate and the upper and lower connecting frame steel plates move smoothly relative to each other, so that stable shearing deformation of the high-damping rubber can be induced. Therefore, it is possible to realize a stable hysteresis shape in a large deformation.

Further, since the upper and lower connecting frame steel plates are directly connected to each other through the intermediate steel plate, the moment arm length of the steel plate is smaller than that of the prior art in which a high-damping rubber is provided between the upper and lower connecting frame steel plates, It is possible to reduce the design moment value for the point where the fixing part of the steel plate, that is, the vibration damper is joined to the upper and lower frames.

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.
