Abstract

To downsize a deformation member.SOLUTION: In a vibration control structure 10, webbing 30 is wound onto a spool 28, and the spool 28 and the webbing 30 are connected to a building. When the building is vibrated, rotation of the spool 28 in a drawing direction is allowed and drawing of the webbing 30 from the spool 28 is allowed due to twisting and deformation of a torsion shaft 34 caused by a turning force in the drawing direction applied to the spool 28 from the webbing 30 in a state where the torsion shaft 34 restrains rotation of the spool 28 in the drawing direction. This structure can increase the absorption amount of vibrational energy of the building due to deformation of the torsion shaft 34, thereby downsizing the torsion shaft 34.SELECTED DRAWING: Figure 5

[0004] [Patent Document 1] Patent Publication No. 2021-127681 Summary of the Invention [Problem to be solved by the invention]

[0005] In consideration of the above, an object of the present invention is to provide a vibration damping structure that can reduce the size of a deformable member. [Means for solving the problem]

[0006] The vibration control structure of the first aspect of the present invention comprises a winding body that is rotatably connected to a structure, a connecting member that is wound around the winding body from a base end and has a tip end connected to the structure and is pulled out from the winding body to rotate the winding body in the pull-out direction, and a deformable member that, when the structure is vibrated, is torsionally deformed by the rotational force of the winding body in the pull-out direction while restricting the rotation of the winding body in the pull-out direction, thereby allowing the winding body to rotate in the pull-out direction and allowing the connecting member to be pulled out of the winding body.

[0007] A vibration damping structure according to a second aspect of the present invention is the vibration damping structure according to the first aspect of the present invention, in which a rotational force is applied to the winding body in the winding direction of the connecting member.

[0008] A vibration-damping structure according to a third aspect of the present invention is the vibration-damping structure according to the first or second aspect of the present invention, in which the winding body and the connecting member are connected in an inclined direction relative to a frame portion of a building.

[0009] The vibration-damping structure of the fourth aspect of the present invention is a vibration-damping structure of any one of the first to third aspects of the present invention, which comprises multiple sets of the winding body, the connecting member and the deformable member, and the connecting direction of the winding body and the connecting member of a first set to the structure and the connecting direction of the winding body and the connecting member of a second set to the structure are opposite in inclination to the structure.

[0010] A vibration-damping structure according to a fifth aspect of the present invention is the vibration-damping structure according to any one of the first to fourth aspects of the present invention, in which the connecting member is movably folded back and connected to the building.

[0011] A vibration-damping structure of a sixth aspect of the present invention is the vibration-damping structure of any one of the first to fifth aspects of the present invention, further comprising an interposition member interposed between at least one of the winding body and the connecting member and the building structure.

[0012] A vibration damping structure according to a seventh aspect of the present invention is the vibration damping structure according to any one of the first to sixth aspects of the present invention, in which the rotation of the winding body in the unwinding direction is stopped. Effect of the Invention

[0013] In the vibration damping structure of the first aspect of the present invention, the winding body is rotatably connected to the building, the connecting member is wound around the winding body from the base end side, and the tip side of the connecting member is connected to the building.

[0014] When the structure is vibrated, the deformable member is twisted by the rotational force of the winding body in the unwinding direction while the deformable member restricts the rotation of the winding body in the unwinding direction, thereby allowing the winding body to rotate in the unwinding direction and allowing the connecting member to be unwound from the winding body. Therefore, the torsional deformation of the deformable member can absorb the vibration energy of the structure and the deformable member can be made smaller.

[0015] In the vibration damping structure of the second aspect of the present invention, a rotational force is applied to the winding body in the winding direction of the connecting member, so that the deformation member can be torsionally deformed after the winding body has wound up the connecting member.

[0016] In the vibration-damping structure of the third aspect of the present invention, the winding body and the connecting member are connected in an inclined direction to the frame of the building, so that the shape of the frame is deformed by vibration of the building, and the connecting member connecting portion of the frame is separated from the winding body connecting portion, so that a force in the pull-out direction of the connecting member can be applied between the connecting member and the winding body, and the deformation member can be twisted.

[0017] The vibration damping structure of the fourth aspect of the present invention includes a plurality of sets of a winding body, a connecting member, and a deformable member.

[0018] Here, the direction in which the first set of winding bodies and connecting members connect to the structure and the direction in which the second set of winding bodies and connecting members connect to the structure are inclined in the opposite direction to the structure, so that vibration to one side of the structure can cause torsional deformation of the first set of deformation members, and vibration to the other side of the structure can cause torsional deformation of the second set of deformation members.

[0019] In the vibration-damping structure of the fifth aspect of the present invention, the connecting member is movably folded back and connected to the structure, which makes it possible to increase the vibration-damping load of the structure by the deformable member.

[0020] In the vibration-damping structure of the sixth aspect of the present invention, an interposition member is interposed between the structure and at least one of the winding body and the connecting member. This allows the connecting member to be short, and the amount of elongation of the connecting member when the structure is vibrated can be reduced.

[0021] In the vibration-damping structure of the seventh aspect of the present invention, the rotation of the winding body in the unwinding direction is stopped. Therefore, the unwinding of the connecting member from the winding body is stopped, and an increase in the amount of vibration of the building can be suppressed. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Fig. 1 shows a front view of a vibration damping structure 10 according to an embodiment of the present invention. In Fig. 1 and other figures, the upper side of the vibration damping structure 10 is indicated by an arrow UP, and one side of the vibration damping structure 10 is indicated by an arrow OS.

[0024] As shown in FIG. 1, a vibration-damping structure 10 according to this embodiment is installed within the wall of a building 12 as a structural object, and the upper side and one side of the vibration-damping structure 10 are oriented upward and horizontally of the building 12, respectively.

[0025] A frame portion 14 having a rectangular shape in a front view is formed on a wall portion of the building 12. One side of the frame portion 14 is made into one side pillar 14A as a first part, and the other side of the frame portion 14 is made into the other side pillar 14B as a second part, and the one side pillar 14A and the other side pillar 14B form the pillars of the building 12. The upper side of the frame portion 14 is made into an upper material 14C as a third part, and the lower side of the frame portion 14 is made into a lower material 14D as a fourth part, and the upper material 14C and the lower material 14D form the upper partition portion 12A (first partition portion) and the lower partition portion 12B (second partition portion) of the building 12, respectively.

[0026] The vibration damping structure 10 is provided with two sets of vibration damping devices 16 (hereinafter, the two sets of vibration damping devices 16 are referred to as a "first vibration damping device 16A" and a "second vibration damping device 16B").

[0027] The vibration damping device 16 is provided with a metallic, generally rectangular upper bracket 18 as a fixing member, and a triangular upper fixing plate 18A is formed to protrude from the upper bracket 18. The vibration damping device 16 is provided with a metallic, generally rectangular lower bracket 20 as a fixing member, and a triangular lower fixing plate 20A is formed to protrude from the lower bracket 20.

[0028] In the first vibration control device 16A, an upper bracket 18 is fixed to the other side of an upper end portion of one side column 14A in the frame 14 of the building 12, and an upper fixing plate 18A of the upper bracket 18 protrudes to the other side. A lower bracket 20 is fixed to one side of a lower end portion of the other side column 14B in the frame 14, and a lower fixing plate 20A of the lower bracket 20 protrudes to one side.

[0029] In the second vibration damping device 16B, an upper bracket 18 is fixed to one side of the upper end of the other-side column 14B, and an upper fixing plate 18A of the upper bracket 18 protrudes to one side. A lower bracket 20 is fixed to the other side of the lower end of the one-side column 14A, and a lower fixing plate 20A of the lower bracket 20 protrudes to the other side.

[0030] The vibration damping device 16 is provided with a winding device 24 (see Figs. 5 and 6). In Figs. 5 and 6, the upper side of the winding device 24 is indicated by an arrow DU, the left side of the winding device 24 is indicated by an arrow DL, and the front side of the winding device 24 is indicated by an arrow DF.

[0031] The winding device 24 is provided with a metal frame 26 having a U-shaped cross section. A back plate 26A is provided on the rear side of the frame 26, and the frame 26 is fixed to the lower fixing plate 20A of the lower bracket 20 by bolts and nuts at the lower end of the back plate 26A, so that the winding device 24 is installed on the vibration damping device 16. In the first vibration damping device 16A, the upper side of the winding device 24 faces upward and toward one side, while in the second vibration damping device 16B, the upper side of the winding device 24 faces upward and toward the other side, and in the first vibration damping device 16A and the second vibration damping device 16B, the left-right direction of the winding device 24 is perpendicular to the front direction of the vibration damping structure 10 (perpendicular to the upper side and one side). Further, the frame 26 is provided with a leg plate 26B and a leg plate 26C on the left and right sides of the device, respectively, and the leg plate 26B and the leg plate 26C face each other in the left-right direction of the device.

[0032] A metallic, substantially cylindrical spool 28 is provided as a winding body between leg plates 26B and 26C, with the axial direction of spool 28 being in the left-right direction of the device. Spool 28 penetrates leg plates 26B and 26C, and spool 28 is rotatably supported by frame 26. The right end of spool 28 is coaxially expanded in diameter to form restriction hole 28A, and the cross section of restriction hole 28A is hexagonal (non-circular).

[0033] A long strip-shaped webbing 30 serving as a connecting member is wound from the base end side around the outer periphery of the spool 28, and the webbing 30 is made of a woven fabric. When the spool 28 is rotated in the winding direction (the direction of arrow A in FIG. 6), the webbing 30 is wound onto the spool 28. On the other hand, when the webbing 30 is pulled out from the spool 28, the spool 28 is rotated in the pulling out direction (the direction of arrow B in FIG. 6). The webbing 30 extends from the frame 26 to the upper side of the device.

[0034] An inner end of a metallic rotation spring 32 (spiral spring) serving as a biasing member is connected to the left end of the spool 28 via a left end of a torsion shaft 34 described below, and the rotation spring 32 is disposed on the left side of the frame 26 (leg plate 26B). An outer end of the rotation spring 32 is connected to the frame 26, and the rotation spring 32 biases the spool 28 in the winding direction, so that a biasing force is applied to the webbing 30 in the winding direction onto the spool 28.

[0035] A metallic, approximately cylindrical torsion shaft 34 is coaxially inserted into the spool 28 as a deformable member, and the left side of the torsion shaft 34 is connected to the left side end of the spool 28 so as to be rotatable together with the left side end of the device, and the left side end of the device protrudes from the spool 28 to the left side of the device.

[0036] A metallic, generally cylindrical lock base 36 is provided coaxially on the right side of the spool 28 as a rotating body. The right side of the torsion shaft 34 is coaxially inserted through the lock base 36, and the lock base 36 is connected to the torsion shaft 34 so as to be rotatable together with the lock base 36. The right side of the lock base 36 is formed as a ratchet 36A, and ratchet teeth 36B are formed on the entire outer periphery of the ratchet 36A. The left side of the lock base 36 is reduced in diameter relative to the ratchet 36A and is coaxially inserted into the regulating hole 28A of the spool 28, and a male thread 36C is formed on the entire outer periphery of the left side of the lock base 36.

[0037] On the right side of the frame 26 (leg plate 26C), a metal plate-shaped lock plate 38 serving as a lock member is supported rotatably at its base end under the lock base 36 (ratchet 36A), and lock teeth 38A are formed at the tip of the lock plate 38. A retention spring 40 (compression coil spring) serving as a retention member is hung between the lock plate 38 and the leg plate 26C, and the retention spring 40 biases the lock plate 38 toward the ratchet 36A, causing the lock teeth 38A to mesh with the ratchet teeth 36B of the ratchet 36A. When the lock base 36 is rotated in the pull-out direction, the lock plate 38 locks the rotation of the lock base 36 (ratchet 36A) in the pull-out direction, thereby locking the rotation of the torsion shaft 34 and the spool 28 in the pull-out direction. On the other hand, when the lock base 36 is rotated in the winding direction, the ratchet teeth 36B move the lock teeth 38A radially outward of the ratchet 36A against the force of the retaining spring 40, and the lock plate 38 is rotated opposite the ratchet 36A, thereby allowing the lock plate 38 to rotate in the winding direction, and thereby allowing the torsion shaft 34 and the spool 28 to rotate in the winding direction.

[0038] A metal, annular stopper 42 is inserted as a stopping member into the restriction hole 28A of the spool 28. The outer periphery of the stopper 42 is hexagonal (non-circular) and is fitted into the restriction hole 28A, so that the stopper 42 rotates integrally with the spool 28. A female screw 42A is formed on the entire inner periphery of the stopper 42, and the female screw 42A is screwed into the male screw 36C of the lock base 36. The stopper 42 is disposed at the left end of the male screw 36C, so that the spool 28 and the stopper 42 are rotated in the pull-out direction relative to the lock base 36, and the stopper 42 moves along the threads of the male screw 36C to the right side of the device (the ratchet 36A side of the lock base 36).

[0039] A metallic brace 44 having a generally long rod shape is interposed between the upper fixing plate 18A of the upper bracket 18 and the winding device 24 as an intermediate member, and the upper end of the brace 44 is fixed to the upper fixing plate 18A with bolts and nuts. In the first vibration damping device 16A, the brace 44 extends in a downward direction as it approaches the other side, and in the second vibration damping device 16B, the brace 44 extends in a downward direction as it approaches one side.

[0040] A first through anchor 48 (see Figs. 2A and 2B, 3A and 3B, and 4A) made of metal and shaped like a substantially triangular plate is fixed to the lower end of the brace 44 by a bolt and a nut as a winding member, and an insertion hole 48A is formed through the first through anchor 48, and a substantially cylindrical winding portion 48B is formed below the insertion hole 48A. In the first through anchor 48, a portion of the webbing 30 in the retractor 24 that is closer to the tip than the spool 28 is inserted through the insertion hole 48A, and the webbing 30 is wound around the winding portion 48B and folded back downward.

[0041] A metal, substantially triangular plate-shaped second through anchor 50 (see Figs. 2A and 2B, and Fig. 4A) is fixed to the lower fixing plate 20A of the lower bracket 20 on the opposite side to the frame 26 (back plate 26A) of the retractor 24 by bolts and nuts together with the frame 26. The second through anchor 50 has an insertion hole 50A and a winding portion 50B formed therein, similar to the first through anchor 48, and the winding portion 50B is disposed above the insertion hole 50A. In the second through anchor 50, a portion of the webbing 30 on the tip side from the first through anchor 48 is inserted into the insertion hole 50A, and the webbing 30 is wound around the winding portion 50B and folded back upward.

[0042] At the lower end of the brace 44, on the opposite side to the first through anchor 48, a metal, approximately rectangular plate-shaped anchor 52 is fixed together with the first through anchor 48 by bolts and nuts as a connecting member, and the tip of the webbing 30 (the portion tip side of the second through anchor 50) is connected to the anchor 52.

[0043] As a result of the above, the webbing 30 is connected to the brace 44, and the extension direction of the portion of the webbing 30 between the spool 28 and the first through anchor 48, the portion between the first through anchor 48 and the second through anchor 50, and the portion between the second through anchor 50 and the anchor 52 is parallel to the extension direction of the brace 44.

[0044] Next, the operation of this embodiment will be described.

[0045] In the vibration control structure 10 configured as described above, when the building 12 is vibrated by an earthquake or the like and the upper partition part 12A (upper material 14C of the frame part 14) is moved reciprocally to one side and the other side relative to the lower partition part 12B (lower material 14D of the frame part 14) of the building 12, the frame part 14 is alternately deformed to one side and the other side into a parallelogram shape when viewed from the front. Therefore, a state in which the distance between the upper bracket 18 and the lower bracket 20 of the first vibration control device 16A is enlarged and the distance between the upper bracket 18 and the lower bracket 20 of the second vibration control device 16B is reduced, and a state in which the distance between the upper bracket 18 and the lower bracket 20 of the second vibration control device 16B is enlarged and the distance between the upper bracket 18 and the lower bracket 20 of the first vibration control device 16A is reduced are alternately repeated.

[0046] Incidentally, when the distance between the upper bracket 18 and the lower bracket 20 of the vibration damping device 16 is expanded, a pull-out force is applied from the spool 28 to the webbing 30 in the retractor 24, and a rotational force in the pull-out direction is applied to the spool 28. Then, in a state in which the lock plate 38 locks the rotation of the lock base 36 in the pull-out direction (a state in which the torsion shaft 34 restricts the rotation of the spool 28 in the pull-out direction), the torsion shaft 34 is torsionally deformed by the rotational force in the pull-out direction applied from the webbing 30 to the spool 28, thereby allowing the rotation of the spool 28 in the pull-out direction and allowing the webbing 30 to be pulled out from the spool 28. Therefore, the torsion shaft 34 absorbs the vibration energy of the building 12 while damping the vibration of the building 12.

[0047] On the other hand, when the distance between the upper bracket 18 and the lower bracket 20 of the vibration damping device 16 is reduced, slack occurs in the webbing 30 in the retraction device 24. Then, in a state in which the lock plate 38 allows the lock base 36 to rotate in the retraction direction, the spool 28 (including the torsion shaft 34 and the lock base 36) is rotated in the retraction direction by the biasing force of the rotation spring 32, whereby the webbing 30 is retracted onto the spool 28, and the slack in the webbing 30 is removed.

[0048] Here, as described above, the torsion shaft 34 is torsionally deformed to absorb the vibration energy of the building 12. Therefore, unlike the case where the torsion shaft 34 is bent to absorb the vibration energy of the building 12, the amount of vibration energy of the building 12 absorbed by the deformation of the torsion shaft 34 can be increased, and the torsion shaft 34 can be made smaller.

[0049] Furthermore, when slack occurs in the webbing 30, the spool 28 is rotated in the winding direction (the webbing 30 is wound around the spool 28) by the biasing force of the rotation spring 32, and the slack in the webbing 30 is removed. Therefore, after the slack in the webbing 30 is removed, a pull-out force from the spool 28 acts on the webbing 30, and the torsion shaft 34 is torsionally deformed. This makes it possible to increase the amount of torsion deformation of the torsion shaft 34, unlike a case in which the torsion shaft 34 is torsionally deformed without removing the slack in the webbing 30, and therefore makes it possible to increase the amount of vibration energy of the building 12 absorbed by the torsion shaft 34. Furthermore, each time slack occurs in the webbing 30, the slack is removed, and therefore the vibration energy of the building 12 can be repeatedly absorbed.

[0050] Furthermore, in the vibration control device 16, the winding device 24 (including the spool 28 and the webbing 30) and the brace 44 are connected in an inclined direction to the frame portion 14 (one side column 14A, the other side column 14B, the upper member 14C, and the lower member 14D) of the building 12. For this reason, the frame portion 14 is deformed into a parallelogram shape when viewed from the front due to vibration of the building 12, and the upper bracket 18 (the portion connecting to the webbing 30) and the lower bracket 20 (the portion connecting to the spool 28) in the frame portion 14 are separated from each other, so that a force in the pull-out direction of the webbing 30 can be applied between the webbing 30 and the spool 28, and the torsion shaft 34 can be twisted and deformed.

[0051] Furthermore, the direction in which the take-up device 24 (including the spool 28 and the webbing 30) and the brace 44 in the first vibration damping device 16A connect to the frame portion 14 is opposite to the direction in which the take-up device 24 (including the spool 28 and the webbing 30) and the brace 44 in the second vibration damping device 16B connect to the frame portion 14. Therefore, the torsion shaft 34 of the first vibration damping device 16A can be twisted by deformation of the frame portion 14 towards one side, and the torsion shaft 34 of the second vibration damping device 16B can be twisted by deformation of the frame portion 14 towards the other side, so that the vibration energy of the building 12 can be absorbed alternately and seamlessly by the torsion shaft 34 of the first vibration damping device 16A and the torsion shaft 34 of the second vibration damping device 16B.

[0052] In addition, a portion of the webbing 30 on the tip side from the spool 28 is folded back at the first through anchor 48 and the second through anchor 50 and connected to the upper bracket 18 (brace 44). Therefore, in order for the torsion shaft 34 to be torsionally deformed, three portions of the webbing 30 need to be pulled from the upper bracket 18. As a result, the load acting on the upper bracket 18 to torsionally deform the torsion shaft 34 in the vibration damping device 16 is three times the torsion deformation load of the torsion shaft 34 (the load for torsionally deforming the torsion shaft 34 when the webbing 30 is connected to the upper bracket 18 without being folded back), so that the vibration damping load of the building 12 by the torsion shaft 34 can be increased. Moreover, compared to when the webbing 30 is connected to the upper bracket 18 without being folded back, the load input to the webbing 30 from the upper bracket 18 can be reduced to one-third, and damage to the webbing 30 can be suppressed.

[0053] Furthermore, a brace 44 is interposed between the webbing 30 and the upper bracket 18. This allows the webbing 30 to be shortened, and when the building 12 is vibrated, the amount of elongation of the entire webbing 30 can be reduced, allowing the torsion shaft 34 to be appropriately twisted and deformed by the pulling force from the spool 28 acting on the webbing 30.

[0054] Furthermore, when the rotation of the spool 28 in the pull-out direction is permitted (when the torsion shaft 34 is torsionally deformed), the spool 28 and the stopper 42 are rotated in the pull-out direction relative to the lock base 36, and the stopper 42 is moved toward the ratchet 36A along the threads of the male screw 36C of the lock base 36. Then, the spool 28 is permitted to rotate a predetermined number of times in the pull-out direction, and the stopper 42 comes into contact with the ratchet 36A, making the spool 28 and the stopper 42 unable to rotate in the pull-out direction relative to the lock base 36, and the rotation of the spool 28 in the pull-out direction is stopped. Therefore, the pulling load of the webbing 30 from the spool 28 is abruptly increased (see FIG. 7), which can suppress an increase in the amount of vibration of the building 12 and appropriately suppress the collapse of the building 12.

[0055] In this embodiment, the portion of the webbing 30 distal from the spool 28 is folded back at two positions. However, the portion of the webbing 30 distal from the spool 28 may be folded back at one position (see FIG. 4(B)), the portion of the webbing 30 distal from the spool 28 may be folded back at three or more positions (see FIG. 4(C)), or the portion of the webbing 30 distal from the spool 28 may not be folded back. In FIG. 4(B), the second through anchor 50 is omitted, and the anchor 52 is fixed to the frame 26. In FIG. 4(C), the first through anchor 48 is added, and the anchor 52 is fixed to the frame 26.

[0056] Furthermore, in this embodiment, the brace 44 is interposed between the webbing 30 and the upper bracket 18. However, the brace 44 may be interposed between the frame 26 and the lower bracket 20. Also, the brace 44 does not have to be provided, and the webbing 30 (anchor 52) may be fixed to the upper bracket 18.

[0057] In this embodiment, the upper bracket 18 and the lower bracket 20 are fixed to the one side pillar 14A or the other side pillar 14B. However, the upper bracket 18 may be fixed to the upper member 14C, and the lower bracket 20 may be fixed to the lower member 14D.

[0058] Furthermore, in this embodiment, the connecting member is the webbing 30. However, the connecting member may also be a wire or a rope.

[0059] In this embodiment, the vibration-damping structure 10 is installed inside the wall of the building 12. However, the vibration-damping structure 10 may be installed inside a pillar of the building 12, inside the upper partition portion 12A, or inside the lower partition portion 12B.

[0060] Furthermore, in this embodiment, the vibration-damping structure 10 is applied to a building 12. However, the vibration-damping structure 10 only needs to be applied to any structure, and may be applied to any structure other than the building 12, a bridge, or a ship. [Explanation of symbols]
