Description

  The present invention relates to a vibration control device capable of suppressing shaking caused by an earthquake and wind, and a building including the vibration control device.

  The present applicant has proposed a toggle vibration control device as a vibration control device that improves the effect of a damper that reduces the vibration of a structure caused by an earthquake and wind (Patent Document 1).

  As shown in FIG. 15, the toggle vibration control device 206 causes the arms 200 and 202 to move in a circular arc in a plane formed by the two arms 200 and 202, and the displacement of the structure is detected at the connecting portion of the arms 200 and 202. This is a mechanism that amplifies and exhibits the damping effect of the damper 204. However, if out-of-plane buckling occurs at the portion of the pin 208 that connects the joints 200A and 202A of the arms 200 and 202, the force transmission mechanism is impaired, and the vibration energy absorption effect is greatly reduced.

  In order to prevent out-of-plane buckling, as shown in FIG. 16, the overlap margin A of the joints 200A and 202A is increased, and the clearance in the orthogonal direction B (out-of-plane direction) is reduced.

As a result, even if out-of-plane buckling starts to occur, the two arms 200 and 202 are designed to move in the in-plane direction by obtaining a restoring force against the out-of-plane buckling by the reaction force of the overlapping portion. Has been.
JP 2004-44755 A

  However, in order to reduce the joint clearance and increase the overlap allowance, the arm joints 200A and 200B require the precision required for the building and the processing precision that is far away. Also, in the construction site, if the clearance is small, the installation work becomes difficult.

  Furthermore, it is also required to improve the vibration control performance than before. When the device is enlarged (when the arms 200 and 202 are lengthened), the vibration control performance can be improved. However, out-of-plane buckling is likely to occur with the increase in size, and as a result, processing and mounting work are further improved. It becomes difficult.

  This invention considers the fact concerned, and makes it a subject to make processing and attachment work easy while improving damping performance.

  In order to achieve the above object, the vibration control device according to claim 1 is a vibration control device provided in a building constructed of columns and beams, and one end of the vibration control device is rotatably connected to the lower floor mounting portion of the lower floor. A second arm having one end rotatably coupled to an upper floor mounting portion of an upper floor that is displaced relative to the lower floor mounting portion when a seismic force acts on the building, and A first connecting member rotatably connecting the other end and the other end of the second arm at a predetermined angle; one end rotatably connected to the first connecting member; and the other end connected to the lower floor mounting portion A first damper that is rotatably connected to the same floor, a third arm having one end rotatably connected to the lower floor mounting portion, and an upper floor mounting portion. A fourth arm having one end rotatably connected thereto, the other end of the third arm, and the other end of the fourth arm A second connecting member that is rotatably connected with a predetermined angle, a second connecting member that is rotatably connected to the second connecting member, and the other end that is rotatably connected to the same floor as the upper floor mounting portion. A second toggle vibration control device comprising two dampers, a fixing member provided between the upper floor and the lower floor, a surface attached to the fixing member and configured by the pillar and the beam An out-of-plane buckling prevention means for restricting movement of the first toggle vibration control device and the second toggle vibration control device to the outside of the first toggle vibration control device is provided.

  The vibration control device according to the first aspect includes two toggle vibration control devices, a first toggle vibration control device and a second toggle vibration control device.

  The first toggle vibration control device is mounted on the upper floor due to an earthquake or the like by rotatably connecting the other end of the first damper whose one end is rotatably connected to the same floor as the lower floor mounting portion to the first connecting member. Even if the relative deformation in the horizontal direction or the vertical direction of the lower part and the lower floor mounting part is small, it is amplified by the large deformation of the connecting part between the other end of the first arm and the other end of the second arm due to geometric characteristics, 1 damper gets a big stroke. For this reason, the relationship of small deformation × large force = large deformation × small force is established, and the first damper suppresses the vibration of the building by the small force.

  Similarly, in the second toggle vibration control device, the other end of the second damper whose one end is rotatably connected to the same floor as the upper floor mounting portion is rotatably connected to the second damper. Suppresses building vibrations with a small force.

  In this way, since the two pairs of the first toggle vibration control device and the second toggle vibration control device are provided, the vibration control performance is significantly improved compared to the conventional one without increasing the size.

  Furthermore, the out-of-plane buckling prevention means restricts the first toggle vibration control device and the second toggle vibration control device from moving outside the surface (out-of-plane buckling).

  Thereby, since the 1st toggle damping device and the 2nd toggle damping device can be operated in a field, the damping device can show sufficient damping effect. Also, for example, the clearance of the joint portion (connecting portion) of the first arm and the second arm and the joint portion (connecting portion) of the third arm and the fourth arm can be reduced or the overlap margin can be increased to increase the out of plane. Since it is not necessary to prevent buckling, the machining accuracy of the joint portion can be lowered, and the mounting operation is facilitated.

  The vibration control device according to claim 2 is a vibration control device provided in a building constructed of columns and beams, and a first arm whose one end is rotatably connected to a lower floor mounting portion of a lower floor, A second arm having one end rotatably connected to an upper floor mounting portion that is displaced relative to the lower floor mounting portion when a seismic force is applied to the building, the other end of the first arm, and the second arm A first connecting member that rotatably connects the other end of the first connecting member with a predetermined angle, one end rotatably connected to the first connecting member, and the other end rotatable to the same floor as the lower floor mounting portion. A first toggle vibration control device including a first damper connected; a third arm having one end rotatably connected to the lower floor attaching portion; and one end rotatably connected to the upper floor attaching portion. The fourth arm, the other end of the third arm, and the other end of the fourth arm are rotated at a predetermined angle. A second connecting member connected to the second connecting member; and a second damper having one end rotatably connected to the second connecting member and the other end rotatably connected to the same floor as the upper floor mounting portion. One end of the 2-toggle damping device and the first connecting member of the first toggle damping device are rotatably connected, and the other end is rotatably connected to the second connecting member of the second toggle damping device. The telescopic connection arm, a fixing member provided between the upper floor and the lower floor, and the connection to the outside of the surface composed of the pillar and the beam attached to the fixing member And an out-of-plane buckling prevention means for restricting movement of the arm.

  The seismic control device according to claim 2 is provided with two pairs of the first toggle seismic control device and the second toggle seismic control device in the same manner as the seismic control device according to claim 1, so that the size is increased. In addition, the seismic performance is much improved than before.

  Furthermore, both ends of the extendable connecting arm are rotatably connected to the first connecting member of the first toggle vibration control device and the second connecting member of the second toggle vibration control device. And the out-of-plane buckling prevention means regulates this connecting arm so as not to move outside the surface (out-of-plane buckling). Therefore, the first toggle vibration control device and the second toggle vibration control device are regulated so as not to move outside the surface (out-of-plane buckling) without hindering the in-plane operation.

  Thereby, since the 1st toggle damping device and the 2nd toggle damping device can be operated in a field, the damping device can show sufficient damping effect. Further, for example, the clearance of the joint between the first arm and the second arm (connection portion) and the joint between the third arm and the fourth arm (connection portion) can be reduced, or the overlap margin can be increased to increase out-of-plane buckling. Therefore, it is possible to reduce the machining accuracy of the joint and to facilitate the mounting operation.

  According to a third aspect of the present invention, there is provided the vibration control device according to the first aspect, wherein the connection arm is rotatably coupled to the first connection member of the first toggle vibration control device. A second joint part rotatably connected to the second connection member of the second toggle vibration control device, a first shaft part provided in the first joint part, and a second joint part. The second shaft portion, and a hollow pipe portion into which the first shaft portion and the second shaft portion are slidably inserted.

  In the vibration control device according to the third aspect, the connecting arm connects the first connecting member and the second connecting member. And this connection arm is provided in the 1st axial part provided in the 1st joint part rotatably connected with the 1st connection member, and the 2nd joint part connected with the 2nd connection member rotatably. The second shaft portion is slidably (expandable) inserted into the hollow pipe portion.

  As described above, since the connecting arm is configured such that both ends thereof are freely rotatable and extendable, even if the first toggle vibration control device and the second toggle vibration control device are connected by the connection arm, the first toggle vibration control device is used. It does not interfere with the operation of the device and the second toggle vibration control device.

  According to a fourth aspect of the present invention, in the structure according to any one of the first to third aspects, the out-of-plane buckling prevention means is slidable in two directions intersecting the fixed member. It features a simple slider mechanism.

  According to a fourth aspect of the present invention, the vibration damping device includes a slider mechanism that is slidable in two directions intersecting the fixed member as out-of-plane buckling prevention means. Therefore, the first toggle vibration control device and the second toggle vibration control device are regulated so as not to move outside the surface (out-of-plane buckling) without being hindered in the in-plane operation.

  According to a fifth aspect of the present invention, in the structure according to any one of the first to fourth aspects, the first toggle vibration control device and the second toggle vibration control device are arranged on a plurality of floors. The fixing member is straddling and is a beam or a stud between the upper floor and the lower floor.

  The seismic control device according to claim 5 is not mounted on the first toggle seismic control device and the second toggle seismic control device on a frame composed of columns and beams constituting the first floor, but mounted across a plurality of floors. ing. For this reason, when the building is shaken by an earthquake, the relative displacement amount between the lower floor mounting portion and the upper floor mounting portion is large, so that the stroke of the damper also increases. For this reason, vibration energy can be absorbed efficiently.

  Furthermore, the number of members is reduced by using a beam or a stud as a fixing member provided with out-of-plane buckling prevention means.

  A building according to a sixth aspect includes the vibration control device according to any one of the first to fifth aspects.

  Since the building of Claim 6 is equipped with the vibration control apparatus of any one of Claims 1-5, the shaking by an earthquake, a wind, etc. is suppressed.

  As described above, according to the present invention, since two pairs of the first and second toggle vibration control devices are provided, the vibration control performance is greatly improved compared to the conventional one without increasing the size. is doing. Furthermore, since the first toggle vibration control device and the second toggle vibration control device are restricted by the out-of-plane buckling prevention means from moving outside the surface (out-of-plane buckling), for example, the joint portion This makes it easy to process and install the material.

  As shown in FIG. 14, the vibration control device 12 of the first embodiment is attached to an existing building 10 composed of a plurality of floors. The building to which the vibration control device 12 is attached is not limited to the number of floors or the structure type (RC building, SRC building, S building, etc.).

  As shown in FIG. 1, the vibration control device 12 includes a first toggle vibration control device 100 and a second toggle vibration control device 150.

  In the first toggle vibration control device 100, a joint plate 24A of the first arm 24 is rotatably connected by a pin 19 to a bracket 80 projecting from a pillar 16B and a corner of a beam 14B on the ceiling of the second floor. A joint plate 30A of the second arm 30 is connected to a bracket 82 projecting from a corner of the beam 14A and the pillar 16A on the first floor so as to be rotatable by a pin 22.

  As shown in FIG. 2, the joint plates 24 </ b> B and 30 </ b> B provided on the free end sides of the first arm 24 and the second arm 30 are connected to each other with a predetermined angle so as to be rotatable by a pin 32. Further, the end of the rod 36A of the damper 36 is rotatably connected to the joint plate 30B by a pin 34. The end of the cylinder 36B of the damper 36 is rotatably connected by a pin 40 to a bracket 84 projecting from the corner of the beam 14A and the column 16B, and can follow the movement of the joint plates 24B and 30B (pin 32). ing.

  Similarly, the joint plate 124 </ b> A of the third arm 124 of the second toggle vibration control device 150 is rotatably connected to the bracket 80 with a pin 119. The bracket 82 is connected to a joint plate 130 </ b> A of the fourth arm 130 so as to be rotatable by a pin 122.

  The joint plates 124B and 130B provided on the free end sides of the third arm 124 and the fourth arm 130 are connected with a predetermined angle so as to be rotatable by a pin 132. Further, the end of the rod 136A of the damper 136 is rotatably connected to the joint plate 130B by a pin 134. The end of the cylinder 136B of the damper 136 is rotatably connected by a pin 140 to a bracket 86 protruding from the corner of the beam 14B and the column 16A, and can follow the movement of the joint plates 124B and 130B (pins 132). ing.

  In addition, the bracket 84 and the bracket 86 are disposed diagonally opposite to each other in the vertical and horizontal directions, and the first toggle vibration control device 100 and the second toggle vibration control device 150 are configured to be point-symmetric.

  A slider device 300 is provided between the side surface of the beam 14C between the beams 14A and 14B and the first arm 24 of the first toggle vibration control device 100.

  As shown in FIGS. 3 and 4, the slider device 300 includes a first rail block 310 having a first rail 310A. The first rail block 310 is fixed to the side surface of the beam 14C so that the first rail 310A is in the horizontal direction.

  The first rail 310A of the first rail block 310 is engaged with the slide block 312 so that the slide block 312 can slide along the first rail 310A.

  The second rail 314A of the second rail block 314 is engaged with the slide block 312 so that the second rail block can slide along the second rail 314A. The second rail 314A is disposed so as to be orthogonal to the first rail 310A. (The second rail 314A is in the vertical direction).

  A cross roller ring 316 that is rotatable about an axis orthogonal to the first rail 310A and the second rail 314A is attached to the second rail block 314, and a mounting block 318 is attached to the cross roller ring 316. ing. The first arm 24 is fixed to the mounting block 318 by welding, bonding, or the like.

  Therefore, the first arm 24 is supported by the slider device 300 so as to be slidable in two directions of horizontal and vertical without being separated from the beam 14C, and orthogonal to the first rail 310A and the second rail 314A. It is supported so as to be rotatable about the axis to be rotated. That is, the movement of the first arm 24 in the plane formed by the beams 14A and 14B and the pillars 16A and 16B is not restricted and is not moved out of the plane.

As shown in FIG. 1, similarly, a slider device 302 is provided between the side surface of the beam 14 </ b> C and the fourth arm 130 of the second toggle vibration control device 150. The slider device 302 has the same configuration as the slider device 300 described above.
Accordingly, similarly, the fourth arm 130 is supported by the slider device 302 so as to be slidable in two directions of horizontal and vertical without being separated from the beam 14C, and is also supported by the first rail 310A and the second rail 314A. It is supported rotatably about an axis perpendicular to the axis. That is, the movement of the fourth arm 130 in the plane is not restricted and the fourth arm 130 is prevented from moving out of the plane.

  Next, the operation of the vibration control device according to the first embodiment will be described.

  As shown in FIGS. 5 to 7, it is assumed that the building 10 is horizontally deformed rightward (FIGS. 5 and 7B) or leftward (FIGS. 6 and 7C) due to earthquakes and winds. . In FIG. 7, in order to make the movements of the first toggle control device 100 and the second toggle control device 150 easy to understand, the deformation is extremely extreme. In fact, the building is deformed so much. There is no.

  Due to such horizontal deformation, the first arm 24 and the second arm 30 of the first toggle vibration control device 100 constituting the vibration control device 12 rotate around the pins 19 and 22. The displacement amount of the pin 32 is amplified and becomes larger than the relative horizontal displacement amount of the pin of the beam 14B on the lower floor 14A.

  Similarly, since the third arm 124 and the fourth arm 130 of the second toggle vibration control device 150 rotate around the pins 119 and 122, the relative relationship between the pins of the upper floor beam 14A and the lower floor beam 14B. The displacement amount of the pin 132 is amplified and becomes larger than the horizontal displacement amount.

  In this way, the small interlayer displacement between the upper-level beam 14A and the lower-level beam 14B separated by two layers is amplified to the large rotational displacement of the pins 32 and 132, and the relationship of small displacement × large force = large displacement × small force is obtained. Is established. That is, the rods 36A and 136A of the dampers 36 and 136 extend greatly, and the vibration of the building 10 is attenuated and effectively damped by a small force.

  In addition, the first and second toggle vibration control devices 100 and 200 are mounted across a plurality of floors instead of attaching the vibration control devices to the single-layer pillars and beams (two levels in this embodiment). . For this reason, when the building 10 is shaken by an earthquake, the strokes of the connected dampers 36 and 136 are increased, and vibration energy can be efficiently absorbed.

  Moreover, since the two toggle vibration control devices of the first toggle vibration control device 100 and the second toggle vibration control device 150 are provided, the vibration control effect can be achieved without increasing the size (without lengthening the arm or the damper). It has improved dramatically.

  Further, the first toggle vibration control device 100 and the second toggle vibration control device 150 are moved out of plane by the slider devices 300 and 302 without interfering with the in-plane operations of the first arm 24 and the fourth arm 130. It is regulated.

  Therefore, since the force transmission mechanism is not impaired, the vibration damping effect can be sufficiently exhibited without reducing the vibration energy absorption effect. Further, unlike the conventional case, it is not necessary to reduce the clearance of the joints 24B and 30B (connection portion) and the joints 124B and 130B (connection portion) or increase the overlap allowance to prevent out-of-plane buckling. In addition, the machining accuracy of the joints 24B, 30B, 124B, and 130B can be reduced, and the mounting operation is facilitated.

  In the present embodiment, in the first toggle vibration control device 100, the slider device 300 is attached to the first arm 24. However, the present invention is not limited to this. Although illustration is omitted, a configuration in which the slider device is attached to the second arm 30 may be employed. Or the structure attached to both the 1st arm 24 and the 2nd arm 30 may be sufficient.

  Similarly, in the second toggle vibration control device 150, the slider device 302 is provided on the fourth arm 130. However, the slider device may be attached to the third arm 124, or the third arm 124 and the fourth arm may be provided. The structure attached to both the arms 130 may be sufficient.

  Next, the vibration control device 112 according to the second embodiment will be described. In addition, the same member as 1st Embodiment is set as the same code | symbol, and the overlapping description is abbreviate | omitted.

  As shown in FIGS. 8 and 9, the vibration control device 112 includes a first toggle vibration control device 101 and a second toggle vibration control device 151 as in the first embodiment. Further, the joint plate 31 </ b> B of the first toggle vibration control device 101 and the joint plate 131 </ b> B of the second toggle vibration control device 151 are connected by the connection arm 500.

  As shown in FIG. 10, the connecting arm 500 has joint portions 502 and 504 at both ends rotatably attached to the above-described joint plates 31 </ b> B and 131 </ b> B (see FIG. 9) by pins 512 and 514. Further, the shaft portions 502 </ b> A and 504 </ b> A of the joint portions 502 and 504 are inserted into the hollow pipe 501. The pipe 501 includes an outer cylinder 510 and inner cylinders 506 and 508, and the inner cylinders 506 and 508 slide and enter and exit from both ends of the outer cylinder 510. The shaft portions 502A and 504A slide the inner cylinders 506 and 508 of the pipe 501, and enter and exit from the ends of the inner cylinders 506 and 508.

  Therefore, as shown in FIGS. 10 (A) and 10 (B), the arm length of the connecting arm 500 is changed by the amount of sliding of the inner cylinders 506 and 508 and the amount of sliding of the shaft portions 502A and 504A. It has a stretchable structure.

  Further, as shown in FIG. 7, a slider device 304 is provided between the side surface of the beam 14 </ b> C and the connecting arm 500.

  The slider device 304 has the same configuration as the slider devices 300 and 302 described in the first embodiment, and the outer cylinder 510 of the connecting arm 500 is fixed to the mounting block 318 by welding, bonding, or the like. (See FIGS. 3 and 4).

  Therefore, the connecting arm 500 is supported by the slider device 304 so as to be slidable in two directions of horizontal and vertical without being separated from the beam 14C, and is orthogonal to the first rail 310A and the second rail 314A. The shaft is supported so as to be rotatable. In other words, the movement of the connecting arm 500 in the plane is not restricted and the movement is prevented from moving out of the plane.

  Next, the operation of the vibration control device according to the second embodiment will be described.

  As in the first embodiment, as shown in FIGS. 11 to 13, the building 10 is moved in the right direction (FIGS. 11 and 13B) or in the left direction (FIGS. 12 and 13 (C) due to an earthquake and wind. )), The vibration of the building 10 is attenuated and controlled by the vibration control device 112. Further, since the vibration control device 112 includes two toggle vibration control devices, the first toggle vibration control device 101 and the second toggle vibration control device 151, the vibration control effect is greatly improved. In FIG. 7, in order to make the movements of the first toggle vibration control device 101 and the second toggle vibration control device 151 easy to understand, they are extremely deformed. In fact, the building is not deformed so much.

  Now, with the above deformation, the positions and intervals of the joint plate 31B of the first toggle vibration control device 101 and the joint plate 131B of the second toggle vibration control device 151 change. That is, the arm length and position (including the angle) of the connecting arm 500 change. However, as described above, the connecting arm 500 is extendable and the joint portions 502 and 504 are rotatably connected to the joint plates 31B and 131B. Therefore, the connecting arm 500 does not hinder the operation of the first toggle vibration control device 101 and the second toggle vibration control device 151.

  The connecting arm 500 is prevented from moving out of the plane by the slider device 304 without interfering with the in-plane operation. Therefore, the connection portion (pin 32) between the first arm 24 and the second arm 31 of the first toggle vibration control device 101 and the connection between the third arm 124 and the fourth arm 131 of the second toggle vibration control device 151. Both of the portions (pins 132) are restricted from moving out of the plane without hindering in-plane movement.

  Therefore, since the force transmission mechanism is not impaired, the vibration damping effect can be sufficiently exhibited without reducing the vibration energy absorption effect. In addition, the machining accuracy of the joints 24B, 31B, 124B, and 131B can be reduced, and the mounting work is facilitated.

  In addition, the single slider device 304 prevents out-of-plane buckling of both the first toggle vibration control device 101 and the second toggle vibration control device 151 (the vibration control device 112 as a whole), so the configuration is simple. And it is low cost.

  In addition, this invention is not limited to the structure of said embodiment.

  For example, in the above-described embodiment, the slider devices 300, 302, and 304 are all attached to the beam 14C, but the present invention is not limited to this. For example, it may be a stud (not shown) provided between the beam 14A and the beam 14B.
