  There are various structures including the above-mentioned structures that can be used to attenuate the deformation of the frame-like body by means of the vibration control means. There is something with which the load acts. In such a vibration control device in which a load acts between constituent members, if the stress based on this load becomes excessive stress, the constituent member will be crushed and deformed, which is not preferable. A device that can prevent the generation of excessive stress is required.

  An object of the present invention is to provide a vibration control device that prevents excessive stress from being generated in a component member and prevents the component member from being crushed and deformed.

  The vibration control device according to the present invention includes a first side and a second side that face each other, the first side and the second side, and the first side and the second side. A frame-like body that includes two right and left third side portions and a fourth side portion that are coupled so as to be swingable in a direction, and at least one of the first side portion and the second side portion Are connected to each other via a vibration control means, and have two swinging center parts shifted in the left-right direction, and these swinging center parts make a left-right direction with respect to the third side part and the fourth side part. And a swing center portion of one of the two swing center portions, and a swing portion of the third side portion and the fourth side portion. One of the side portion on the moving center side and the rocking body is configured to be slidable in the left-right direction, and the piece member has a left-right direction. It has is, is characterized in that the flat portion contacting one the surface of said oscillator with the side portion of the one pivot center side of the is provided.

  In this seismic control device, the frame-like body is deformed by the first side portion swinging in the left-right direction with respect to the second side portion due to the occurrence of an earthquake or the like. Swinging in the left-right direction with respect to the third and fourth sides around the swing center, and the piece member constituting the one swing center with respect to the one side One of the side part on the side of the swing center and the swinging body slides in the left-right direction, and is thereby connected to at least one of the first side part and the second side part via the vibration control means. Since the swing is expanded at the position of the swing body, the vibration control means has a vibration control function to attenuate the vibration by converting the vibration energy into heat energy. The vibration that deforms the body is controlled.

  In particular, in this vibration control device, when the vibration that deforms the frame-like body is controlled by the vibration control means, the piece member and the one rocking center that slides in the left-right direction with respect to the piece member The swinging body swings in the left-right direction with respect to the third side part and the fourth side part about the two swinging central parts between one of the side part and the swinging part. As a result, a load in the vertical direction is generated, but the piece member has a length in the left-right direction. Since the flat part which is in surface contact with one side is provided, the load acting on the unit area of the piece member, that is, the stress is reduced.

  For this reason, excessive stress does not act between the structural members which comprise a seismic control apparatus, and it can prevent that crushing deformation | transformation etc. arise in these structural members.

  In the above, the member that slides in the left-right direction with respect to the piece member may be a rocking body or a side portion on the one rocking center side.

  In addition, when the member that slides in the left-right direction with respect to the piece member is the side portion on the one swinging center portion side, the piece member is placed on the side portion on the one swinging center portion side in the left-right direction. It is inserted into an opening formed with a length, and by this opening, the side portion on the one swinging center portion side with respect to the piece member can be slid in the left-right direction, and the piece member The flat portion comes into surface contact with a portion that is long in the left-right direction of the opening.

  In this way, the member that slides in the left-right direction with respect to the piece member is a side portion on the one swing center portion side, and the side portion on the one swing center portion side is the thickness of the swing body. In the case where two support members facing the rocking body are formed on both sides in the vertical direction, the openings are formed in these support members, and thus the openings are long in the left-right direction. You may make the said flat part of a piece member surface-contact with each support member in a location.

  According to this, since the member where the flat portion of the piece member is in surface contact becomes two support members, it is possible to increase the area where the surface contact is made, and to reduce the stress generated between the piece member and the support member. become.

  In this way, when an opening having a length in the left-right direction is provided on the rocking body or the side part on the one rocking center side, the opening may be a long hole, and one end in the left-right direction. The opening may be a notch or the like having an opening end, or an opening of any form.

  Further, when the piece member constituting the one swinging center portion is a first piece member and the other swinging center portion is configured to include a second piece member, the first piece member is It is preferable to form by chamfering for providing the flat portion to a component having the same shape and size as the second piece member.

  According to this, since the parts for the first piece member can be made the same as the second piece member, and the parts can be made common, it is possible to reduce the types of parts that must be prepared, Reduction of manufacturing cost can be achieved.

  In the present invention described above, the vibration control means may be an elastic member such as rubber or a spring, or may be an oil damper, a friction damper, or the like. You can use seismic means.

  In addition, the vibration control device according to the present invention can be applied to an arbitrary structure such as a building or a bridge (including an iron bridge and a pedestrian bridge), and when the vibration control device is applied to a building such as a house, the effective arrangement thereof. One of the places is a wall. And when the damping device according to the present invention is arranged on the first floor wall, it is possible to suppress the vibration from the foundation due to the earthquake or the like from propagating to the second floor, and arranged on the upper floor wall of the second floor or more. In this case, it is possible to suppress the lower floor shaking from propagating to the upper floor.

  Further, the posture of the vibration control device when the vibration control device according to the present invention is arranged in the structure is arbitrary, and for example, the vibration control device may be in a vertical posture as in the case where the vibration control device is arranged on the wall, or When placed on the floor, ceiling, etc., the posture may be horizontal, and the posture should be arbitrary depending on the type of structure to which the vibration control device is applied and the location of the structure where vibration control is required. Can do.

  FIG. 5 is a deformation schematic diagram exaggeratingly illustrating the deformation of the frame-like body 30 at the time of occurrence of an earthquake or the like, as described above, and the upper side 1 and the lower side by the shafts 21, 22, 23, 24. 2 and the side portions 3 and 4 are connected by A, B, C and D, the connecting portion of the swinging body 40 and the upper side portion 1 by the rubber 50 is E, and the swinging body 40 and the lower side portion 2 are connected. A connecting portion by the rubber 50 is indicated by F, and two swinging central portions by the swinging center structures 51 and 52 are indicated by G and H, respectively. These A to H are positions before the frame-shaped body 30 is deformed, whereas A ′, C ′, E ′, F ′, G ′, and H ′ are deformed by the frame-shaped body 30. The positions of A, C, E, F, G, and H are shown.

  When the frame 30 is deformed in a rhombus shape by swinging the upper side 1 in the left-right direction with respect to the lower side 2 with the load W, the swinging body 40 is moved to the left and right side parts 3, 4. It swings in the left-right direction around the two swing center portions G and H connecting the side portions 3 and 4 and the swing body 40. Since the distance from the midpoints I to E of G and H and the distance from the midpoints I to F are larger than the distance between the swing center portions G and H, the connecting portion between the swing body 40 and the upper side portion 1. E and F which is a connecting portion between the rocking body 40 and the lower side portion 2 are enlarged by the lever principle and greatly moved in the left-right direction. Since these E and F are composed of rubber 50 having a high damping property, the vibration with respect to the lower side 2 of the upper side 1 due to an earthquake or the like is attenuated by these rubbers 50, that is, vibration due to an earthquake or the like. The energy is converted into the thermal energy of the rubber 50, and in a house where the vibration control device according to the present embodiment is built in and arranged on the first floor wall, the vibrations in the left and right directions on the second and higher floors are suppressed.

  In FIG. 5, a two-dot chain line 40 ′ indicates a swinging state of the swinging body 40 when the frame-shaped body 30 is deformed, and I ′ is a position of the midpoint I when the frame-shaped body 30 is deformed. Is shown.

  When the frame body 30 is deformed into a rhombus shape as described above, the swing center portion G moves while drawing an arc locus J centering on B, and the swing center portion H is an arc track centering on D. Since the movement of the swinging body 40 moves in the direction of K, and there is a vertical difference between the positions of the two swinging central portions G and H, the swinging of the swinging body 40 in the left-right direction as described above is 2 This is performed on the condition that the rocking body 40 slightly slides in the left-right direction with respect to one of the rocking center portions G and H. In this embodiment, the piece member 73 of FIG. 4 constituting the rocking center portion H on the right side of FIG. 5 is a long hole 78 formed in the main body 41 of the rocking body 40 with a length in the left-right direction. Therefore, the rocking body 40 is swung in the left-right direction because the elongated hole 78 moves in the left-right direction with respect to the piece member 73, that is, the rocking body 40 is on the right side of FIG. 4 by sliding in the left-right direction.

  When such swinging and sliding of the swinging body 40 occurs, as shown in FIG. 5, H before the deformation of the frame-shaped body 30 is at the position H ′ after the deformation of the frame-shaped body 30. Since there is a vertical difference between these H and H ′, a load in the vertical direction acts between the piece member 73 and the elongated hole 78, and this load is Since the oscillating body 40 is oscillated in the horizontal direction on the basis of this principle, it becomes extremely large.

  However, in the present embodiment, flat portions 73D that are elongated in the left-right direction are formed on the upper and lower surfaces of the piece member 73, and the elongated holes 78 are formed with long portions 78A on the left and right that face these vertically. Therefore, the surface contact between the flat portion 73D and the portion 78A reduces the stress that is a load per unit area that acts between the piece member 73 and the elongated hole 78. For this reason, the elongated deformation of the elongated hole 78 in the vertical direction that occurs when the piece member 73 is a simple circular cylindrical part like the piece member 63 of the swinging central structure 51 shown in FIG. In other words, the main body 41 of the oscillating body 40 is not crushed and deformed at the portion of the long hole 78, and the original shape and function of the constituent members constituting the vibration control device according to the present embodiment are not generated. The rocking body 40 can be swung while being maintained, whereby the original vibration control action by the vibration control device can be exhibited.

  5 also moves to the position of G ′ after the deformation of the frame-shaped body 30, and there is a vertical difference between these G and G ′. A load in the vertical direction is applied between the constituent members constituting the swing center portion G, but the swing center portion G is configured to support the circular cylindrical piece member 63 with the support members 15 and 16. And, it is configured to be inserted into the round holes 66, 67, 68 formed in the main body 41 of the rocking body 40, and since the surface contact is originally between these, excessive stress is not generated.

  The swinging of the swinging body 40 is performed by sliding the swinging body 40 in the left-right direction with respect to the piece member 73 of the swinging center structure 52, thereby swinging with respect to the lower side 2 of the upper side 1. However, such vibration control is not performed by sliding the oscillating body 40 with respect to the piece member of the oscillating central structure 52, but with respect to this piece member. This can also be realized by sliding the support members 17 and 18 in the left-right direction.

  FIG. 6 shows an embodiment in which the support members 17 and 18 of the side portion 4 are slid in the left-right direction with respect to the piece member of the swing center structure 52 as described above.

Further, the swinging body 40 swings in the left-right direction by sliding the elongated holes 86, 87 formed in the support members 17, 18 of the side portion 4 in the left-right direction with respect to the piece member 83. At this time, a large load in the vertical direction acts between the piece member 83 and the long holes 86 and 87, but the piece member 83 and the long holes 86 and 87 are both flat in the left-right direction. Since the surfaces 86A and 87A are in surface contact, the piece member 83 and the long holes 86 and 87 are not subjected to such a large stress as to expand and deform the long holes 86 and 87 up and down.

  In this embodiment, the long holes 86 and 87 having the portions 86A and 87A facing the flat portion 83D of the piece member 83 in the up and down direction face the main body 41 on both sides in the thickness direction of the main body 41 of the rocking body 40. Since the two support members 17 and 18 can be formed, the total thickness of the support members 17 and 18 is made larger than the thickness of the main body 41, whereby the magnitude of the stress is changed to the embodiment shown in FIG. Can be made smaller.

  Further, according to this embodiment, by providing the flat part 83D by chamfering on the same part as the part for the piece member 63 in the other oscillating structure 51, the piece member for the oscillating center structure 52 is provided. 83 can be formed, and the parts of both the piece members 63 and 83 can be made common, so that parts management can be facilitated and the manufacturing cost of the entire vibration control device can be reduced.
