  However, in buildings such as skyscrapers and pencil buildings, bending deformation is the main component, and it is difficult to obtain a sufficient seismic control effect. Therefore, it is required to suppress the bending deformation of the building and to effectively obtain a large seismic control effect.

  In view of the above, an object of the present invention is to provide a vibration control device capable of effectively suppressing a bending deformation of a building and effectively obtaining a large vibration control effect.

  The vibration control device according to claim 1 is provided in a rectangular frame constituting the building, and has one end at a corner formed by the upper beam or the upper beam and one column constituting the frame. One end is rotatably attached to a corner portion composed of a first arm rotatably attached and a lower beam or the lower beam and the other pillar constituting the frame, and the other end and the other of the first arm. A second arm rotatably connected to the end at a predetermined angle, and one end rotatably connected to a connecting portion between the first arm and the second arm, and the upper beam of the frame or the A first damping device for attenuating vibration of the frame having a damping damper rotatably connected to a corner formed by an upper beam and the other column; and the other of the frame Provided on the outside of the column, and expands and contracts with the horizontal deformation of the frame An inertial mass damper that converts a linear displacement in the axial direction into a rotational displacement around the axis of the rotational inertial mass by a rolling mechanism, and an axial force in a direction opposite to the direction of the axial force acting on the other column. And a second vibration control device that acts on.

  Therefore, the second seismic control device applies an axial force on the other column opposite to the direction of the axial force acting on the other column, so that the axial deformation of the other column is constrained, and as a result, the entire building Bending deformation is suppressed. This also controls the building.

  On the other hand, in the first seismic control device, even if the frame (upper beam and lower beam) is relatively small in the horizontal direction, it is amplified to a large deformation and the damping damper is linearly displaced in the axial direction (extension and contraction). To do).

  The relationship of smaller deformation × large force = large deformation × small force is established, and a large damping effect is obtained, and the building is damped.

  Here, the first seismic control device causes the first seismic control mechanism to apply the axial force in the same direction as the axial force acting on the other column along with the horizontal deformation of the frame.

  However, as described above, the second vibration control device causes the axial force in the opposite direction to the axial force acting on the other column to act on the other column, so that the axial deformation of the other column is constrained, Bending deformation of the entire building is suppressed. Therefore, a great vibration control effect can be obtained. In other words, the cooperation of the first vibration control device and the second vibration control device provides a greater vibration control effect than a configuration in which two vibration control devices are simply provided.

  In addition, the displacement in the tangential direction in the rotational direction of the rotational inertial mass of the inertial mass damper is larger than the linear displacement (expansion / contraction) in the axial direction of the inertial mass damper. Therefore, the rotational inertial mass effect caused by the rotation of the rotational inertial mass can be greatly amplified with respect to the rotational inertial mass. That is, even if the mass of the rotary inertia mass damper is light, a large mass is obtained by converting the axial displacement into the rotation of the rotary inertia mass.

  Furthermore, when the axial displacement amount of the linear displacement of the inertial mass damper is x, the tangential displacement of the mass body is

And the acceleration is

It is. That is, the inertial mass damper is subjected to a force in the direction opposite to the axial displacement direction.

  Therefore, by using the inertial mass damper, it is possible to cause the second seismic control device to act on the other column with an axial force opposite to the direction of the axial force acting on the other column (to suppress bending deformation of the entire building). For example, it becomes possible without using a complicated mechanism, and a great vibration control effect can be obtained.

  The vibration control device according to claim 2, wherein the second vibration control device has one end of the inertial mass damper rotatably attached to the other pillar of the frame, and the other end of the inertial mass damper is It is rotatably attached to the lower beam outside the other column or the ground outside the building.

  Therefore, the second vibration control mechanism is such a simple mechanism, and can cause the axial force acting in the opposite direction to the axial force acting on the other column to act on the other column as the frame is deformed in the horizontal direction. .

  The vibration control device according to claim 3, wherein the second vibration control device includes a third arm having one end rotatably attached to the other column of the frame, and a lower beam outside the other column. Or, a fourth arm in which one end is rotatably attached to the ground outside the building, and the other end and the other end of the third arm are rotatably connected at a predetermined angle, and the third arm, One end is rotatably connected to the connection portion with the fourth arm, and one end is rotatably connected to the connection portion between the third arm and the fourth arm, and the lower beam, the ground, The inertia mass damper having the other end rotatably connected to any one of corners formed by the lower beam or the ground and the other column.

  Therefore, even if the second damping device is relatively deformed in the horizontal direction by the toggle mechanism, it is amplified to a large deformation, and the inertia mass damper is linearly displaced (stretched) in the axial direction. The relationship of smaller deformation × large force = large deformation × small force is established, and a large damping effect can be obtained by the small force.

  Thus, since the 2nd damping device can acquire a big damping effect by a toggle mechanism, the bending deformation of the whole building is suppressed effectively, As a result, a building is controlled effectively.

  By adopting such a configuration for the second seismic device, the second seismic control mechanism causes the axial force in the opposite direction to the axial force acting on the other column as the frame is deformed in the horizontal direction. Make it work.

  In the vibration control device according to a fourth aspect, the other pillar is a pillar disposed in the outermost part of the building.

  Therefore, since the deformation of the axial force of the other pillar arranged in the outermost part of the building is restrained, the bending deformation of the entire building is effectively suppressed, and as a result, the entire building is effectively damped. .

  In the vibration control device according to claim 5, the first vibration control device is provided in a lowermost frame.

  Therefore, since the lowermost frame of the building is controlled, bending deformation of the entire building is effectively suppressed, and as a result, the entire building is effectively controlled.

  The vibration control device according to claim 6, wherein the rotation mechanism of the inertial mass damper includes a shaft body, a rotating body into which the shaft body is inserted, a holding body that rotatably holds the rotating body, A screwing means provided on an outer peripheral surface of the shaft body and an inner peripheral surface of the rotating body, for converting a linear displacement in the axial direction of the shaft body into a rotational displacement around the axis of the rotating body; And a mass body rotating around the axis.

  Therefore, when the shaft body of the inertia mass damper is linearly displaced, the rotating body into which the shaft body is inserted is rotationally displaced by the screwing means. A large inertial mass is generated by rotating the mass body around the axis integrally with the rotating body. This provides a great damping effect and effectively dampens the entire building.

  The vibration control device according to a seventh aspect includes an energy absorber between the outer peripheral surface of the rotating body and the inner peripheral surface of the holding body.

  Therefore, energy is absorbed by the rotation of the rotating body, and the response value becomes small.

  The vibration control device according to claim 8, wherein the movable wall is disposed in a space portion partitioned by the frame portion constituting the building, and the movable wall of the frame portion is deformed in a horizontal deformation of the frame portion.

And an inertial mass damper having a rotation mechanism that converts a linear displacement of a connecting portion between the frame portion and the movable wall into a rotational motion of a mass body.

  Therefore, with the horizontal deformation of the frame portion, the movable wall rotates in the same direction as the displacement direction of the frame portion. In the inertial mass damper connected to the frame portion and the movable wall, the connection portion between the frame portion and the movable wall generated by the in-plane rotation of the movable wall is linearly displaced. When the inertial mass damper is linearly displaced in the axial direction in this way, the mass body rotates around the axis. The vibration energy is absorbed by the rotational inertia force of the mass body. That is, the deformation of the frame portion is suppressed and the vibration is controlled.

  Here, the displacement in the tangential direction in the rotational direction of the mass body is larger than the linear displacement (expansion / contraction) in the axial direction of the inertial mass damper. Therefore, the inertial mass effect caused by the rotation of the mass body can be greatly amplified with respect to the additional inertial mass. That is, even if the mass body of the inertial mass damper is light, a large inertial mass is obtained by converting the linear linear displacement into the rotational motion of the mass body, and a large damping effect is obtained.

  If the axial displacement amount of the linear displacement of the inertial mass damper is x, the tangential displacement of the mass body is

And the acceleration is

It is. That is, the inertial mass damper is subjected to a force in the direction opposite to the axial displacement direction.

  Therefore, in the case of an inertial mass damper, by rotating the movable wall in the same direction as the deformation of the frame, a force acts in a direction opposite to the rotation direction, that is, a direction opposite to the horizontal displacement of the frame.

  As a result, deformation of the frame is constrained, so that bending deformation of the entire building is suppressed, and as a result, a great seismic control effect is obtained.

  The vibration control device according to claim 9, wherein the frame portion is a rectangular frame, and a mounting portion to which the connecting member is rotatably attached is provided at a beam or a corner portion constituting the frame. .

  Therefore, the seismic control device restrains the deformation in the axial direction of the column by applying an axial force on the column opposite to the direction of the axial force acting on the column as the frame is deformed. Deformation is suppressed, and as a result, a great seismic control effect is obtained.

  A vibration control device according to a tenth aspect is applied to a frame disposed in an outermost part of the building.

  Therefore, since the axial deformation of the columns arranged in the outermost part of the building is restricted, the bending deformation of the entire building is effectively suppressed, and as a result, the entire building is effectively damped.

  A vibration control device according to an eleventh aspect is applied to a frame arranged in the lowermost layer of the building.

  Therefore, since the lowermost frame of the building is controlled, bending deformation of the entire building is effectively suppressed, and as a result, the entire building is effectively controlled.

  The vibration control device according to claim 12, wherein the movable wall has a hexagonal shape, and is arranged so that two opposing sides are substantially horizontal, and the connecting member is the two sides arranged substantially horizontally. The inertia part is connected to the remaining two corners and the frame.

  Therefore, the four connecting members and the four inertia mass dampers are efficiently arranged in the space partitioned by the rectangular frame. Moreover, it is excellent in design property.

  The vibration control device according to claim 13, wherein the rotation mechanism of the inertial mass damper includes a shaft body, a rotating body into which the shaft body is inserted, a holding body that rotatably holds the rotating body, Screwing means provided on the outer peripheral surface of the shaft body and the inner peripheral surface of the rotating body, for converting linear motion in the axial direction of the shaft body into rotational motion about the axis of the rotating body, and integral with the rotating body The mass body rotating around an axis, and one end of either the shaft body or the holding body is connected to the frame body, and the other of the shaft body and the holding body The end portion of this is connected to the movable wall.

  Therefore, when the shaft body of the inertia mass damper is linearly displaced, the rotating body into which the shaft body is inserted is rotationally displaced by the screwing means. A large inertial mass is generated by rotating the mass body around the axis integrally with the rotating body. This provides a magnitude attenuation effect and effectively dampens the entire building.

  The vibration control device according to claim 14 is characterized in that an energy absorber is provided between an outer peripheral surface of the rotating body and an inner peripheral surface of the holding body.

  Therefore, since the energy absorber is provided between the outer peripheral surface of the rotating body and the inner peripheral surface of the holding body, the response value becomes small due to the absorption effect of the rotational energy of the mass body due to the rotation of the rotating body. Therefore, the cross-sectional areas of the connecting member and the inertia mass damper can be reduced.

In addition, a toggle type vibration control device 650 is provided on the rightmost frame 540 (the frame 540 surrounded by the columns 516 and 518 and the beams 520 and 522) in the lowermost layer.

  A toggle-type vibration control device 600 provided on the leftmost frame 530 in the figure includes a first arm 604 having one end fixed to a rotary bearing 602 attached to a corner composed of an upper beam 522 and a column 512, A second arm 608 having one end fixed to a rotary bearing 606 attached to a corner portion constituted by a column 510 and a lower beam 520 is provided. Note that the rotary bearing 602 may be attached to the upper beam 522. Similarly, the rotary bearing 606 may be attached to the lower beam 520.

  The other ends (free ends) of the first arm 604 and the second arm 608 are connected with a predetermined angle so as to be rotatable by a rotary hinge 610. The rotary hinge 610 is connected to the end of the shaft 622 of the elastic-plastic damper 620. Further, a hinge 626 provided at the end of the holder 624 of the elasto-plastic damper 620 is connected to a rotary bearing 628 attached to a corner portion formed by the upper beam 522 and the column 510.

  In the present embodiment, the first arm 604 is shorter than the second arm 608, and the free ends of the first arm 604 are connected at a predetermined angle so as to be rotatable as described above, and the first arm 604 is also connected. And the 2nd arm 608 forms the mountain shape (the shape of a round shape) which becomes convex shape toward the diagonally upper left in the figure.

  A vibration control device 710 having an inertial mass damper 100 is provided on the right outer side (outside of the building 500) in the drawing of the building 500. In addition, since it is the same structure except being bilaterally symmetric with the damping device 700, detailed description is abbreviate | omitted.

  As described above, the vibration control device 550 (the toggle-type vibration control device 600 and the vibration control device 700) and the vibration control device 552 (the toggle-type vibration control device 650 and the vibration control device 710) are subject to the left and right ends of the building 500. Is arranged.

  Next, the inertial mass damper 100 will be described with reference to FIGS.

  3 is a partial sectional perspective view of the inertial mass damper 100, FIG. 4A is a sectional view along the axial direction of the inertial mass damper 100, and FIG. 4B is a front view. FIG. 4C is a diagram showing a modification of the mass body described later.

  As shown in FIGS. 3, 4 (A), and 4 (B), the inertial mass damper 100 has a female thread groove 102 </ b> A formed on the outer peripheral surface of the shaft 102. The female screw groove 102A is inserted into a cylindrical rotating body 110 having a male screw 110A screwed into the female screw groove 102A formed on the inner peripheral surface.

  The rotating body 110 is rotatably held inside a cylindrical holder 104 that is open on one side. The rotating body 110 includes a cylindrical part 111D, and a first disk part 111A, a second disk part 111B, and a third disk part 111C having a larger diameter than the cylindrical part 111D.

  One end side of the rotator 110 protrudes from the opening of the holder 104, and a first disk portion 111 </ b> A is formed at one end of the rotator 110. In addition, a third disc portion 111 </ b> C is formed at the other tip portion of the rotating body 110. Further, the second disc portion 111B and the third disc portion 111C are arranged in the holder 105.

  In addition, concave portions 114 and 115 into which the second disc portion 111B and the third disc portion 111C are fitted are formed at both end portions of the holder 104 corresponding to the second disc portion 111B and the third disc portion 111C. The recesses 114 and 115 are provided with bearings 112 and 113, respectively. With such a configuration, the rotating body 110 rotates around the axis indicated by the arrow K, but movement in the axial direction indicated by the arrow S is restricted.

  Inertial mass damper 100 may be provided with an energy absorber between the holder 104, the inner peripheral surface, and the outer peripheral surface of cylindrical portion 110D of rotating body 110, so that inertial mass damper 100 also has a function as a damping means. it can. In the present embodiment, a viscoelastic liquid is injected as an energy absorber between the holder 104, the inner peripheral surface, and the outer peripheral surface of the cylindrical portion 110D of the rotating body 110. It is sealed with an oil seal (not shown) or the like in order to prevent the viscoelastic liquid from leaking. Moreover, the structure which does not provide the energy absorber between the holder 104, an inner peripheral surface, and the outer peripheral surface of the cylindrical part 110D of the rotary body 110 may be sufficient.

  A disk-shaped mass body 120 is fastened to the first disk portion 111 </ b> A of the rotating body 110 with a bolt 122. A circular opening 120A is formed at the center of the mass body 120, and the shaft 102 passes through the opening 120A. In addition, since the inner diameter of the opening 120A is sufficiently larger than the outer diameter of the shaft 102, the opening 120A and the shaft 102 are not in contact with each other. Further, the axis of the rotating body 110 (the first disk portion 111A, the second disk portion 111B, the third disk portion 111C, and the cylindrical portion 111D), the axis of the mass body 120, and the axis of the shaft 102 are on the same axis. is there.

  As shown in FIG. 4C, as a modification of the mass body 120, the mass body 120 may be configured by two members, a semicircular mass body 120B and a mass body 120C. With such a configuration, only the mass bodies 120B and 120C can be easily attached and detached. Therefore, tuning (the operation of adjusting the weight of the mass body) is easy.

  Since the inertial mass damper 100 has the above-described configuration, as shown in FIGS. 3 and 4 (A), the shaft 102 is shown as an arrow S in a state where the holder 104 is fixed. When moving in the direction, the female thread groove 102A on the outer peripheral surface of the shaft 102 and the rotating body 110 male screw 110A are screwed together, and the rotating body 110 rotates around the axis. Further, as shown in FIGS. As shown, the mass body 120 fastened by the rotating body 110 and the bolt 122 rotates around the axis as indicated by the arrow K (the rotating body 110 and the mass body 120 rotate together in the direction of the arrow K). .

  That is, the inertial mass damper 100 is a damper having a mechanism for converting the linear displacement (arrow S) in the axial direction of the shaft 102 into the rotational displacement (arrow K) of the mass body 120 that is the inertial mass.

  As described above, the hinge 101 attached to the end of the shaft 102 of the inertial mass damper 100 is connected to the rotary support 704 described above, and the hinge 105 attached to the end of the holder 104 is connected to the rotary support 702. (See FIG. 1).

  Next, the operation of this embodiment will be described.

  FIG. 13A shows a building (super high-rise building) 500 in a state where the vibration control devices 550 and 552 are not provided. When the building 500 vibrates due to an external force such as an earthquake or wind, the entire building 500 is bent and deformed as shown in FIG. In addition, when it deform | transforms in the arrow G direction, the pillar 510 is a tension | pulling side pillar, the pillar 518 is a compression side pillar, and bending deformation of the whole building arises by the axial deformation | transformation of each pillar. Note that FIG. 13B is exaggerated from the actual one so that the bending deformation can be easily understood.

  When the entire building 500 is bent and deformed in this way, it is difficult to obtain a sufficient vibration control effect. In other words, for example, even if only the toggle-type vibration control devices 600 and 650 are installed, it is difficult to obtain a sufficient vibration control effect. Therefore, in the present embodiment, the seismic control devices 700 and 710 apply an axial force opposite to the direction of the axial force acting on the columns 510 and 518 to restrain the deformation of the columns 510 and 518 in the axial direction. The bending deformation of the entire building 500 is suppressed, and as a result, a large vibration control effect is obtained. Therefore, this will be described in detail.

  As shown in FIG. 2, when the building 500 moves horizontally in the direction of arrow G (right side) due to vibration such as ground motion, it is composed of the leftmost frame 530 (upper beam 522, lower beam 520, column 510, column 512). The rectangular frame 530) thus deformed into a substantially parallelogram shape. Thereby, the upper beam 522 moves horizontally in the direction of the arrow G (the upper beam 522 and the lower beam 520 move relatively). More precisely, since the entire building 500 is bent and deformed (see FIG. 13B), the upper beam 522 is deformed so that the left end (joint end with the column 510) is raised (the rotating bearing 602 and the rotating bearing). 702, and so on). Therefore, an axial force acts on the column 510 in the direction of being pulled upward.

  At this time, in the vibration damping device 700, the interval between the rotary bearing 702 and the rotary bearing 704 is separated, and the inertia mass damper 100 is extended.

  Thus, when the shaft 102 of the inertial mass damper 100 expands and contracts (linear displacement) in the axial direction, as described above, the rotating body 110 rotates around the axis, and the mass body 120 further rotates around the axis (the rotating body 110). And the mass body 120 rotate as a unit). That is, the axial inertia of the column 510 is restrained by the rotational inertia force of the mass body 120, and as a result, the frame 530 is damped.

  The tangential displacement in the rotational direction of the inertial mass damper 110 can be amplified up to several tens of times the axial displacement of the shaft 102 (rotational gain).

  Further, when the axial displacement amount of the linear displacement of the inertial mass damper 100 is x, the displacement in the tangential direction of the mass body is

And the acceleration is

  It is. That is, the inertia mass damper 100 is subjected to a force in the direction opposite to the axial displacement direction. Therefore, an axial force is applied to the column 510 in the direction of pressing downward by the vibration control device 700.

  On the other hand, as the frame 530 is displaced in the horizontal direction in the direction of arrow G (deformed into a substantially parallelogram shape), the distance between the rotary bearing 602 and the rotary bearing 606 is increased, and the first arm 604 and the second arm 608 are connected. The rotating hinge 610 as a part moves to the lower right. As the rotary hinge 610 moves, the entire length of the elastic-plastic damper 620 extends.

  At this time, the amount of displacement of the rotary hinge 610, that is, the amount of axial displacement (elongation) of the elasto-plastic damper 620 is amplified and increased by the toggle mechanism from the horizontal displacement of the rotary bearing 602. That is, the toggle mechanism amplifies a small displacement of the rotary bearing 602 to a large displacement of the rotary hinge 610, and a relationship of small displacement × large force = large displacement × small force is established. Then, deformation of the frame 530 is suppressed by the elastic-plastic damper 620. That is, the frame 530 is controlled (the vibration of the frame 530 is attenuated).

  Here, a tensile force acts on the elasto-plastic damper 620 of the toggle type vibration control device 600. For this reason, the toggle type vibration control device 600 applies an axial force to the column 510 in the direction of pulling upward. Further, as described above, due to the bending deformation of the building 500, an axial force acts on the column 510 in the direction of being pulled upward.

  However, as described above, the inertial mass damper 100 of the vibration damping device 700 acts in a direction opposite to the axial displacement direction, so that the axial force is exerted in the direction in which the column 510 is pressed downward by the vibration damping device 700. Join.

  As described above, due to the bending deformation of the vibration control device 600 and the building 500, an axial force is applied to the column 510 in the direction of pulling upward, but an axial force is applied to the column 510 in a direction of pressing downward by the vibration control device 700 ( The axial force acting on the column 510 is reduced).

  Therefore, since the axial deformation of the pillar 510 is restrained, the bending deformation of the entire building 500 is suppressed, and as a result, a great seismic control effect is obtained. In other words, the toggle type vibration control device 600 and the vibration control device 700 cooperate to obtain a greater vibration control effect than a configuration in which two vibration control devices are simply provided.

  On the other hand, the upper beam 522 is moved in the direction of the arrow G by the deformation of the substantially parallelogram of the frame 540 at the right end of the lowermost layer (a rectangular frame 540 constituted by the upper beam 522, the lower beam 520, the column 516, and the column 518). Move horizontally (the upper beam 522 and the lower beam 520 move relative to each other). In addition, as described above, since the entire building 500 is bent and deformed (see FIG. 13B), the right end of the upper beam 518 (joint end with the column 518) is deformed (rotation). The bearing 602 and the rotary bearing 702 are deformed so as to be lowered). Therefore, an axial force acts on the column 518 in a direction in which it is pressed downward.

  At this time, in the vibration control device 710, the interval between the rotary bearing 702 and the rotary bearing 704 is narrowed, and the inertia mass damper 100 is shortened.

  Thus, when the shaft 102 of the inertial mass damper 100 is shortened in the axial direction (linear displacement), as described above, the rotating body 110 rotates around the axis, and the mass body 120 further rotates around the axis (the rotating body 110). And the mass body 120 rotate as a unit). That is, the axial inertia of the column 518 is restrained by the rotational inertia force of the mass body 120, and as a result, the frame 540 is damped.

  The inertia mass damper 100 is subjected to a force in a direction opposite to the axial displacement direction. Therefore, an axial force is applied to the column 518 in the direction of pulling upward by the vibration control device 710.

  On the other hand, as the frame 540 at the right end of the lowermost layer is displaced in the horizontal direction in the arrow G direction (deformed into a substantially parallelogram shape), the distance between the rotary bearing 602 and the rotary bearing 606 of the toggle type vibration control device 650 is narrow. Thus, the rotary hinge 610, which is a connecting portion of the first arm 604 and the second arm 608, moves upward and obliquely to the right. As the rotary hinge 610 moves, the total length of the elastic-plastic damper 620 is shortened.

  At this time, the toggle mechanism similarly amplifies the small displacement of the rotary bearing 602 to the large displacement of the rotary hinge 610, and the relationship of small displacement × large force = large displacement × small force is established. Then, deformation of the frame 540 is suppressed by the elastic-plastic damper 620. That is, the frame 540 is controlled.

  Here, a compressive force is applied to the elastic-plastic damper 620 of the toggle-type vibration control device 650. For this reason, the toggle type vibration control device 650 applies an axial force to the column 518 in the direction of pressing downward. Further, as described above, the axial force acts on the column 518 in the direction of pressing down due to the bending deformation of the entire building 500.

  On the other hand, as described above, the inertial mass damper 100 of the vibration control device 710 exerts a force in the direction opposite to the axial displacement direction, and thus the axial force is applied to the column 518 by the vibration control device 710 in the upward pulling direction. (Axial force acting on the column 518 is reduced).

  Therefore, since the axial deformation of the column 518 is constrained, bending deformation of the entire building 500 is suppressed, and as a result, a great seismic control effect is obtained. In other words, the toggle-type seismic control device 650 and the toggle-type seismic control device 730 cooperate to provide a greater seismic control effect than a configuration in which two seismic control devices are simply provided.

  In addition, when the building 500 moves horizontally in the direction opposite to the arrow G direction (left side), each operation is left-right symmetric and in the opposite direction, and only a force acts in the opposite direction, and detailed description thereof is omitted.

  Further, like the vibration control devices 550 and 552 of the present embodiment, the outer columns 510 and 518 (the columns arranged on the outermost side of the building 500) that constitute the frames 530 and 540 of the outermost portion of the lowermost layer of the building 500 By restraining the deformation in the axial direction of 510, 518), the bending deformation of the entire building 500 is most effectively damped, and as a result, the greatest vibration damping effect is obtained most effectively.

  Next, a building provided with the vibration control device of the second embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the member same as 1st embodiment, and the overlapping description is abbreviate | omitted.

  FIG. 5 is a front view schematically showing the structure of a building 500 including the vibration control devices 560 and 562 of the second embodiment. As shown in FIG. 5, the vibration control device 560 includes a toggle type vibration control device 600 and a toggle type vibration control device 720, and the vibration control device 562 includes a toggle type vibration control device 650 and a toggle type vibration control device 730. It is configured.

  A toggle type vibration control device 600 is provided on the leftmost frame 530 in the lowermost layer of the building 500. In addition, a toggle type vibration control device 650 is provided on the rightmost frame 540 in the lowermost layer.

  A toggle type vibration control device 720 having an inertial mass damper 100 is provided on the left outer side (outside of the building 500) of the building 500.

  The toggle-type vibration control device 720 includes a third arm 714 having one end fixed to a rotation bearing 702 attached to the column 510 at a position corresponding to the rotation bearing 628 and one end fixed to a rotation bearing 713 fixed to the ground 490. And a fourth arm 718.

  The other ends (free ends) of the third arm 714 and the fourth arm 718 are connected with a predetermined angle so as to be rotatable by a rotary hinge 716. A hinge 101 provided at the end of the inertia mass damper 100 shaft 102 is connected to the rotary hinge 610. Further, a rotary bearing 712 provided at a corner portion where the hinge 105 provided at the end of the holder 104 of the inertial mass damper 100 is constituted by the column 510 and the ground 490 is fixed.

  In the present embodiment, the third arm 714 is longer than the fourth arm 718, and the free ends of the third arm 714 are connected at a predetermined angle so as to be rotatable as described above. 714 and the fourth arm 718 form a chevron shape that is convex toward the lower right in the drawing. Note that the third arm 714 may be shorter than the fourth arm 718.

  A toggle-type vibration control device 730 having an inertial mass damper 100 is provided on the right outer side (outside of the building 500) in the drawing of the building 500.

  The toggle-type vibration control device 730 has the same configuration as the toggle-type vibration control device 720 except that it is bilaterally symmetric.

  In this way, the vibration control device 560 (the toggle-type vibration control device 600 and the toggle-type vibration control device 720) and the vibration control device 562 (the toggle-type vibration control device 650 and the toggle-type vibration control device 730) are connected to the left and right ends of the building 500. The left and right objects are arranged in the part.

  Next, the operation of this embodiment will be described.

  As shown in FIG. 6, when the building 500 moves horizontally in the direction of arrow G (right side) due to vibrations such as earthquake motion, the toggle-side vibration control device 720 causes the interval between the rotary bearing 702 and the rotary bearing 713 to be separated. A rotary hinge 716, which is a connecting portion between the arm 714 and the fourth arm 718, moves upward to the left. As the rotary hinge 716 moves, the entire length of the inertial mass damper 100 is extended.

  At this time, the toggle mechanism amplifies and increases the displacement amount of the rotary hinge 716, that is, the displacement amount (extension) in the axial direction of the inertial mass damper 100, from the horizontal displacement amount of the rotary bearing 702. That is, the toggle mechanism amplifies a small displacement of the rotary bearing 702 to a large displacement of the rotary hinge 716, and a relationship of small displacement × large force = large displacement × small force is established. Then, the inertial mass damper 100 restrains the deformation of the column 510 in the axial direction, and the frame 530 is damped.

  Here, as described above, an axial force acts on the column 510 in a direction of being pulled upward by bending deformation of the toggle-type vibration control device 600 and the building 500.

  However, as described above, the inertial mass damper 100 has a force acting in the direction opposite to the axial displacement direction, so that the third arm 704 of the toggle-type vibration control device 720 can push the column 510 in the direction of pressing downward. A force is applied (the axial force acting on the column 510 is reduced).

  Therefore, since the axial deformation of the pillar 510 is restrained, the bending deformation of the entire building 500 is suppressed, and as a result, a great seismic control effect is obtained. In other words, the toggle-type vibration control device 600 and the toggle-type vibration control device 720 cooperate to obtain a greater vibration control effect than a configuration in which two vibration control devices are simply provided.

  On the other hand, in the toggle-side vibration control device 730, the interval between the rotary bearing 702 and the rotary bearing 713 is narrowed, and the rotary hinge 716, which is a connecting part of the third arm 714 and the fourth arm 718, moves downward to the left. . As the rotary hinge 716 moves, the overall length of the inertial mass damper 100 becomes shorter. Thereby, the axial deformation of the column 510 is constrained, and the frame 530 is controlled.

  Similarly, as described above, due to the bending deformation of the toggle-type vibration control device 650 and the building 500, an axial force is applied to the column 518 in a direction of pressing downward.

  However, as described above, the inertial mass damper 100 is subjected to a force in the direction opposite to the axial displacement direction. Therefore, the third arm 704 of the toggle type vibration control device 730 causes the column 518 to be pulled upward. Power is added. Therefore, an axial force is applied to the column 518 in the direction of pulling upward by the vibration control device 710 (the axial force acting on the column 518 is reduced).

  Therefore, since the axial deformation of the column 518 is restrained, the curved deformation of the entire building 500 is suppressed, and as a result, a great vibration control effect is obtained. In other words, the toggle-type seismic control device 650 and the toggle-type seismic control device 730 cooperate to provide a greater seismic control effect than a configuration in which two seismic control devices are simply provided.

  When the building 500 moves horizontally in the direction opposite to the arrow G direction (left side), each operation is left-right symmetric and in the opposite direction, and each force only acts in the opposite direction.

  In the first embodiment and the second embodiment, the vibration control devices 550 and 560 and the vibration control devices 552 and 562 are arranged on the left and right ends of the building 500 so as to deform the columns 510 and 518 in the axial direction. By restraining, the bending deformation of the whole building 500 is effectively suppressed, but it is not limited to this.

  For example, when there is no space for installing the damping devices 700 and 710 and the toggle type damping devices 720 and 730 outside the building, FIG. 7 showing a modification of the first embodiment and a modification of the second embodiment As shown in FIG. 8, the vibration control devices 700 and 710 and the toggle type vibration control devices 720 and 730 are installed on the frames 530 and 540 in the building, and the toggle type vibration control devices 600 and 650 are installed. It may be installed at 532, 542 to control the vibration. In this case, the bending deformation of the entire building 500 is suppressed by restraining the axial deformation of the columns 512 and 516.

  In the case of such a configuration, the seismic control effect of the entire building 500 is lower than that of the first embodiment and the second embodiment, but a sufficiently large seismic control effect is obtained as compared with the configuration to which the present invention is not applied. be able to.

  Or although illustration is abbreviate | omitted, you may apply this invention not to the lowest layer (1st floor part) but to the 2nd floor part or the 3rd floor part. Even in such a configuration, the seismic control effect of the entire building 500 is lower than that of the first embodiment and the second embodiment, but a sufficiently large seismic control effect is obtained as compared with the configuration to which the present invention is not applied. Can do.

  In the first embodiment and the second embodiment described above, the elastic device 600, 650 uses the elastic-plastic damper 620 as the damping damper, but is not limited thereto. It may be a viscous damper, a viscoelastic damper, a rigid elastic damper, or a damper configured by combining them. In other words, the first vibration control device (the vibration control device 600, 650) may have a damping damper having at least one of viscosity, viscoelasticity, elastoplasticity, or rigid plasticity.

  Next, a vibration damping device 800 according to the third embodiment will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the member same as 1st embodiment and 2nd embodiment, and the overlapping description is abbreviate | omitted.

  In the present embodiment, the vibration control devices are provided on the leftmost frame 530 and the rightmost frame 540 in FIG. 1 in the lowermost layer of the building 500. However, the vibration control device of the frame 530 is illustrated and described as a representative. To do.

  As shown in FIG. 9, the vibration control device 800 includes a hexagonal plate in a plan view in a space defined by a rectangular frame 530 formed of an upper beam 522, a lower beam 520, and pillars 510 and 512 in a building 500. A movable wall 50 is provided. The movable wall 50 is disposed such that the two opposing corners 52C and 52F protrude outward in the horizontal direction, and the two opposing sides 54A and 54D are substantially horizontal. The movable wall 50 is a wall with high in-plane rigidity that does not undergo shear deformation.

  Brackets 42, 44, 46, and 48 are provided at the four corners of the rectangular frame 530. A cylindrical (bar-shaped) connecting member 202 connects the bracket 42 and the corner 52A of the movable wall 50. Similarly, the connecting member 204 connects the bracket 44 and the corner 52B of the movable wall 50, the connecting member 206 connects the bracket 46 and the corner 52D of the movable wall 50, and connects the bracket 48 and the corner 52E of the movable wall 50. The members 208 are connected to each other.

  The connecting members 202, 204, 206, 208 are connected to the brackets 42, 44, 46, 48 and the corners 52A, 52B, 52D, 52E of the movable wall 50, 202A, 202B, 204A, 204B, 206A, 206B. , 208A, 208B are attached so as to be rotatable in the in-plane direction.

  As schematically shown in FIG. 11, the axes of the connecting members 202, 204, 206, and 208 have an angle with a diagonal line 50 </ b> T that connects the connecting portions 202 </ b> B, 204 </ b> B, 206 </ b> B, and 208 </ b> B with the movable wall 50. Furthermore, the extension lines 202T and 204T of the connecting members 202 and 204 intersect above the intersection of the diagonal line 50T (the center of rotation of the movable wall 50), and the extension lines 206T and 208T of the connecting members 206 and 208 are the same as the diagonal line 50T. It intersects below the intersection (rotation center of the movable wall 50).

  As shown in FIG. 9, one end of the inertial mass damper 100L and the inertial mass damper 100P is connected to the corner portion 52F protruding outward in the horizontal direction of the movable wall 50 so as to be capable of in-plane rotation, and the inertial mass damper 100L. The other end is connected to the bracket 42, and the other end of the inertia mass damper 100 </ b> P is connected to the bracket 48.

  Similarly, one end of the inertia mass damper 100M and the inertia mass damper 100N is connected to the corner portion 52C protruding outward in the horizontal direction of the movable wall 50 so as to be rotatable in the plane, and the other end of the inertia mass damper 100M is connected to the bracket. 44, and the other end of the inertial mass damper 100N is connected to the bracket 46.

  Next, the inertial mass dampers 100L, 100M, 100N, and 100P are the same as the inertial mass damper 100 described in the first embodiment and the second embodiment, and thus description thereof is omitted.

  Next, the operation of this embodiment will be described.

  As shown in FIG. 10, when the building 500 moves horizontally in the direction of arrow G (right side) due to vibration such as earthquake motion, a rectangular frame 530 composed of an upper beam 522, a lower beam 520, a column 510, and a column 512 is formed. , Deformed into a substantially parallelogram shape. Thereby, the upper beam 522 moves horizontally in the direction of the arrow G (the upper beam 522 and the lower beam 520 move relatively). Thus, as the frame 530 is displaced in the horizontal direction in the arrow G direction (deformed into a substantially parallelogram shape), the movable wall 50 rotates in-plane in the direction of the arrow R, which is the same direction as the deformation of the frame 530. To do.

  In FIG. 2, the upper beam 522 moves horizontally to the right, and the movable wall 50 rotates in-plane clockwise (clockwise). Further, FIG. 2 shows the deformation and rotation extremely larger than the actual size in order to make the deformation and rotation easy to understand.

  Now, with the rotation of the movable wall 50, the distance between the hinges 101L, 101N and the hinges 105L, 105N, which are the connecting portions of the inertial mass dampers 100L, 100N, becomes narrow, that is, the inertial mass damper 100L. 100 full length shrinks. On the other hand, the distance between the hinges 101M, 101P and the hinges 105M, 105P, which are connecting portions of the inertial mass dampers 100M, 100P, becomes narrow, that is, the total length of the inertial mass dampers 100M, 100P decreases. At this time, the expansion and contraction amounts of the inertial mass dampers 100L, 100M, 100N, and 100P are amplified with respect to the deformation of the frame 530 (hereinafter referred to as “grid magnification”).

  Thus, when the shaft 102 of the inertial mass damper 100 expands and contracts (linear displacement) in the axial direction, as described above, the rotating body 110 rotates around the axis, and the mass body 120 further rotates around the axis (the rotating body 110). And the mass body 120 rotate as a unit). That is, input of vibration such as an earthquake can be reduced by the rotational inertia force of the mass body 120. Thereby, the vibration of the building 500 is suppressed (input reduction effect).

  The tangential displacement in the rotational direction of the rotating body 110 can be amplified to several tens of times the axial displacement of the shaft 102 (rotational amplification factor). Amplified.

  So, for example,

  Rotational gain: βf = 25

  Lattice magnification: βt = 4

  Then,

(Βf · βt) ² = 1000 times

  It becomes.

  That is, the rotational inertial mass effect generated by converting the axial displacement into the rotation of the mass body 120 can be amplified to 10,000 times the mass of the mass body 120.

  Therefore, if the mass of the mass body is 500 kg, an inertial mass of 5,000 tons is generated. In this embodiment, four inertial mass dampers 100 are attached to one frame 530, so that the inertial mass is four times as much as 20,000 tons as a whole.

  In addition, since the viscoelastic liquid is injected into the inertial mass damper 100 between the holder 104, the inner peripheral surface, and the outer peripheral surface of the cylindrical portion 110D of the rotating body 110, the inertial mass damper 100 receives resistance due to the shear resistance of the viscoelastic liquid. . Therefore, a viscoelastic damping force is generated when the rotating body 110 rotates. As a result, the vibration control effect is improved.

  In the inertial mass damper 100, when the displacement amount in the axial direction is x, the displacement in the tangential direction of the mass body 120 is

  And the acceleration is

  It becomes. That is, the inertial mass damper 100 generates a force in a direction opposite to the axial displacement direction.

  Therefore, when the inertial mass damper 100 is used, the movable wall 50 is rotated in-plane in the same direction as the displacement direction of the frame 530 (frame body), thereby opposing the horizontal displacement of the frame 530 (frame body) (arrow). Q) Resistance works.

  As described above, in the vibration control device 800, when the movable wall 50 rotates in the same direction as the frame 530 due to the input displacement, the inertial mass damper 100 contracts and the inertial force generated by the rotation of the mass body 120 causes the earthquake. Because it absorbs energy, it exhibits a high vibration control effect.

  Further, by adopting the configuration as shown in FIG. 9, the four connecting members and the four inertia mass dampers are efficiently arranged in the space in the rectangular frame, and the design is excellent. .

  Further, a tensile force acts on the conventional connection members 202 and 208. For this reason, a force acts in a direction in which the column 510 is contracted with respect to a force in which the column 510 is extended along with the deformation. Therefore, the axial force of the pillar 510 is reduced.

  Similarly, a compressive force acts on the conventional connecting members 204 and 206. For this reason, the column 512 is pressed with the deformation, and the force acts in the direction of pulling out the column 512 against the force. Therefore, the axial force of the column 512 is reduced.

  Further, by restraining the axial deformation of the outer pillars 510 and 518 (the pillars 510 and 518 arranged on the outermost side of the building 500) constituting the frames 530 and 540 of the outermost part of the lowermost layer of the building 500, The bending deformation of the entire building 500 is most effectively controlled, and as a result, the most effective large vibration control effect is obtained.

  In the third embodiment, as shown in FIGS. 9 to 11, the axes of the connecting members 202, 204, 206, 208 are diagonal lines 50 </ b> T connecting the connecting portions 202 </ b> B, 204 </ b> B, 206 </ b> B, 208 </ b> B with the movable wall 50. The extension lines 202T and 204T of the connecting members 202 and 204 intersect above the intersection of the diagonal lines 50T (the center of rotation of the movable wall 50), and the extension lines 206T and 208T of the connecting members 206 and 208 are diagonal lines. Although it was the structure which cross | intersects below 50T intersection (rotation center of the movable wall 50), it is not limited to this. As the frame 530 (frame portion) is displaced in the horizontal direction, the frame 530 (frame portion) and the movable wall 50 are moved so that the movable wall 50 rotates in-plane in the same direction as the displacement direction of the frame 530 (frame portion). What is necessary is just to be connected.

  For example, as shown in FIG. 12, the corners 52A and 52B of the movable wall 50 and the brackets 312 provided on the upper beam 522 are coupled by the coupling members 302 and 304 as shown in FIG. A configuration in which the portions 52D and 52F and the bracket 314 provided on the lower beam 520 are connected by connecting members 306 and 308 may be employed. The connecting member 302 and the connecting member 304 are arranged in a letter C shape, and the connecting member 306 and the connecting member 308 are arranged in an inverted letter C shape.

  Further, for example, in the above-described embodiment, the frame portion is a rectangular frame 530 composed of beams and columns, but is not limited thereto. For example, it may be partitioned with a pillar and a floor. Further, the shape of the frame portion may not be rectangular.
