[0012]
[Operation and effect of the invention]
  As described above, the invention according to claim 1 includes a rigid contact portion provided in a state of being integrally displaced with the wall of the house, a collision mass provided in a floating state in the vibration direction of the wall with respect to the contact portion, A vibration damping device having a gap formed between them and an elastic body interposed between the collision mass and the contact portion is mounted on the wall to suppress the vibration of the wall.
[0013]
  This damping device works as follows.
  In other words, in the case of this vibration damping device, when the wall starts to vibrate, the contact portion is displaced integrally therewith and starts to vibrate in synchronization with the wall.
  On the other hand, since the collision mass is in a floating state in the vibration direction with respect to the contact portion, that is, freely moves independently in the same direction with respect to the contact portion, it collides with the contact portion when the contact portion vibrates, It acts to counteract vibrations, i.e. wall vibrations.
[0014]
  At this time, the kinetic energy is given to the collision mass colliding with the hitting part in the opposite direction (therefore, part of the vibration energy of the hitting part is absorbed as the kinetic energy of the collision mass), and the collision mass is in the reverse direction. Do exercise.
  Then, it collides again with the contact surface at a position opposite to the first contact surface, and again acts to cancel the vibration of the contact portion, that is, the wall.
[0015]
  The collision mass then repeats the same movement in the opposite phase to the hit part and absorbs the vibration energy of the hit part at each collision, and converts it into its own kinetic energy and collides with the vibrating hit part. to continue. As a result, the vibration energy of the wall is attenuated by the energy absorption by the sliding friction at that time, and the vibration is effectively suppressed.
[0016]
  If both the contact portion and the collision mass are made of a rigid body, a large abnormal noise (collision noise) is generated at the time of collision.
  However, in the vibration damping device of the present invention, since an elastic body is formed on at least one contact surface of the contact portion and the collision mass, there is no problem that a large noise is generated at the time of the collision. When a viscoelastic body such as resin is used, vibration energy is converted and absorbed into heat by the viscous behavior of the elastic body at the time of collision, and this also attenuates vibration of the contact portion, that is, the wall.
[0017]
  It is also conceivable to attach a dynamic damper to the wall to suppress wall vibration.
  In this dynamic damper, a damper mass is added to a wall (vibrating member) via a spring, and the natural frequency of the additional vibration system composed of the damper mass and the spring is changed to the natural frequency of the main vibration system (the natural frequency of the wall). By tuning with respect to (frequency), it is possible to reduce the wall resonance magnification and control the vibration.
[0018]
  However, the vibration suppression by the dynamic damper only exhibits an effect on the vibration of a single resonance frequency, and cannot effectively prevent the resonance of other frequencies. That is, it is not effective for resonance at a plurality of frequencies.
  In addition, in the case of a dynamic damper, there is a problem that another new resonance occurs before and after the resonance point.
  In addition, when a rubber elastic body is used as the spring, the spring constant of the rubber elastic body changes depending on the temperature, so that the temperature dependency of the characteristics is high, and the vibration damping efficiency decreases at high and low temperatures.
[0019]
  In addition, the dynamic damper requires a large mass as the damper mass (a mass of about 10% of the vibration member is required), which increases the weight of the entire device, requires a large installation space, and can be further damped. Various problems are inherent in that the direction is fixed and does not work effectively against multi-directional vibrations.
[0020]
  However, in the vibration damping device of the present invention, the collision mass is provided so as to be able to move independently, and this is moved in an opposite phase to the wall to be damped, so that the vibration energy is absorbed and attenuated. Not particularly, vibration can be suppressed over a wide frequency range, and the collision direction can be easily and easily taken in multiple directions. Multidirectional vibration can be suppressed, and temperature dependence It is small and exhibits a good vibration damping effect over a wide temperature range from high to low.
  In addition, the required mass of the collision mass is light and sufficient (about 5% of the vibration member's mass is sufficient), the required space for the entire device is small and compact, and it can be easily mounted on the wall. have.
[0021]
  FIG. 1 schematically shows an embodiment of the vibration damping device of the present invention in comparison with a dynamic damper. In the figure, 1 represents the vibration damping device and 2 represents a dynamic damper.
  Reference numeral 3 denotes a collision mass in the vibration damping device 1, 4 denotes an elastic body formed on the outer peripheral surface of the collision mass 3, that is, a contact surface, 5 denotes a housing forming a contact portion, and 6 denotes a damper mass in the dynamic damper 2. , 7 indicates a spring (rubber), and 8 indicates a vibration member.
[0022]
  FIG. 1B shows the vibration damping effect when the vibration damping device 1 is mounted on the vibration member 8 in comparison with a case where the dynamic damper 2 is mounted and a case where they are not mounted.
  However, in FIG. 1B, c shows a case where the vibration damping device 1 is attached, b shows a case where the dynamic damper 2 is attached, and a shows a case where none of them is attached.
  As can be seen from the vibration damping characteristics of FIG. 1B, when the dynamic damper 2 of FIGS. 1A and 1A is mounted, resonance is suppressed in a specific frequency region (here, the region on the high frequency side). Although it is possible, another new resonance is generated before and after the resonance point, and it is not effective for the resonance on the low frequency side, but the vibration damping device 1 of FIGS. In this case, the effect is exhibited both on the high frequency side and on the low frequency side, and another phenomenon that another new resonance occurs before and after the resonance point does not occur.
[0023]
  As is apparent from the above, it can be seen that the vibration damping device of the present invention can satisfactorily suppress the vibration in the wall.
  This wall damping device can satisfactorily prevent sound having a frequency of about 40 to 200 Hz caused by wall vibration.
  Here, the vibration damping device can be mounted inside or inside the wall, or in some cases, can be mounted outside.
[0024]
  In the present invention, the vibration damping device can be attached to the entire wall depending on the case, but it is usually sufficient to install the vibration damping device partially on a part of the wall. The material cost and processing cost can be reduced compared with the case where the soundproofing material is sandwiched or pasted over the entire surface, and the construction work is particularly simplified, and the cost of the soundproofing wall construction can be reduced.
  In addition, the vibration damping device of the present invention has an advantage that it can be easily attached to an existing wall by retrofitting.
[0025]
  In the present invention, the rigid contact portion can be made of a metal such as iron or aluminum alloy, a hard resin, or other hard material.
  The collision mass itself can be formed of an elastic body such as rubber or resin. However, in this case, it is desirable to configure it as high specific gravity rubber, high specific gravity resin or the like in which metal powder or the like is mixed.
[0026]
  Moreover, this collision mass can also be made into a foam, when this is comprised with an elastic body.
  However, it is desirable that the collision mass is made of a metal such as iron, an aluminum alloy, or lead in order to achieve more effective vibration suppression.
[0027]
  In the present invention, the gap has an important meaning in causing the collision mass to collide most effectively against the hit portion. In this sense, the gap is preferably 0.05 to 2.0 mm, and more preferably The range is 0.2 to 1.0 mm.
[0028]
  In the present invention, rubber or resin can be used as the elastic body.
  Here, various rubbers such as diene rubbers such as NR, SBR and BR, EPDM rubbers, urethane rubbers, and silicon rubbers can be used as the rubber.
  Examples of the resin include thermoplastic resins such as polypropylene and polyamide, polyolefin, urethane, polyester-based thermoplastic elastomers, and the like.
[0029]
  In the present invention, the vibration damping device is provided with a rigid housing that forms a floating chamber therein, and the collision mass is movably accommodated in the floating chamber..
  In this case, a plurality of idle chambers can be formed in the housing, and a collision mass can be accommodated in each of them..
  By doing in this way, the wall damping action of a wall can be performed more effectively.
[0030]
  Further, the collision mass can be formed into a longitudinal shape, and a contact surface along the longitudinal direction can be made to collide with a contact portion such as a housing..
  Alternatively, the collision mass can be made spherical and accommodated in a floating chamber that also forms a spherical space..
[0031]
  In the present invention, the housing is configured with a separate cap for closing the openings at both ends of the skeleton member, which is a wall construction material, into a cylindrical shape. By doing in this way, the number of members required for a soundproof wall structure can be decreased, and a structure can be simplified more.
[0032]
  Alternatively, the skeleton member is made of a C-shaped material, and the housing is constituted with a separate lid that closes the open surface along the longitudinal direction.
[0033]
  Claim 1 above, 2Can be applied to the door that is the wall of the entrance opening.TheAs a result, it is possible to prevent generation of noise and sound transmission due to vibration of the door.
  Here, the door may be a rotary door, or may be a sliding door or other types of doors.
[0034]
  Next claim3, 4Is a vibration control device that has the same structure as described above and is mounted on the ceiling of the house so as to control the ceiling. In this case as well, the vibration control device operates in the same manner as described above, and therefore also described above. Has the same effect as.
[0035]
  One claim5, 6The thing which attached the damping device which consists of the same composition as the above to the roof of a house, and was made to dampen the roof. Even in this case, the damping device has the same operation as the above. The vibration control effect is exhibited, and therefore the same effect as described above can be obtained.
[0036]
  In the present invention, an elastic body may be provided so as to cover the entire contact surface of the collision mass, but an elastic body may be provided so as to partially cover a part of the contact surface..
  For example, a rubber elastic body can be provided so as to cover the outer peripheral surface of both ends of the collision mass having a longitudinal shape or the outer peripheral surface of both ends and both end surfaces.
  In this way, when an elastic body is provided so as to partially cover the collision mass, the mold structure for molding becomes simple, and the amount of the elastic body required is small, thereby reducing the cost. You can also.
[0037]
【Example】
  Next, embodiments of the present invention will be described in detail with reference to the drawings.
  FIG. 2 shows the interior of the house. In the figure, 10 is a floor, 12 is a wall, 14 is a door forming a part of the wall, that is, a door serving as an entrance / exit wall, and 16 is a ceiling.
[0038]
  Figure 3referenceThe structure of the example soundproof wall is shown. In the figure, the wall 12 has a skeleton member 18 such as a stud and surface materials 20 and 23 on both sides thereof.
  When the wall 12 is a wall that partitions the inside and outside of the house, the surface material 23 is an exterior material, and 20 is an interior material. If the wall 12 is an indoor partition wall, both the surface materials 20 and 23 are interior materials.
[0039]
  A damping device 22 is attached to the wall 12.
  Here, the vibration damping device 22 is attached to the back side of the surface material 20, but may be attached to the back side of the surface material 23 in some cases. Alternatively, it is possible in some cases to attach the vibration damping device 22 to the outer surface of the surface material 20 or 23. This point is the following examplesAnd reference examplesThe same applies to.
[0040]
  Further, in this example, the vibration damping device 22 is used in combination with a heat insulating material 24 and a soundproof material 26 of the same type as conventionally used.
[0041]
  FIG. 4 shows a specific configuration of the vibration damping device 22.
  As shown in the figure, the vibration damping device 22 has a metal housing 25.
  The housing 25 has fixing portions 27 at both ends, and is fixed to the wall 12 by fixing tools such as screws in fixing holes 29 of the fixing portions 27.
[0042]
  Inside the housing 25, a floating chamber 28 forming a cylindrical space is provided side by side, and a cylindrical collision mass 30 having a cylindrical shape is movably accommodated inside the floating chamber 28. Here, the impact mass 30 has an outer diameter smaller than the inner diameter of the idler chamber 28 by a predetermined dimension.
[0043]
  These collision masses 30 are entirely covered with a rubber elastic body 32 layer. The layer of the rubber elastic body 32 may be applied to the outer peripheral surface of the collision mass 30 by vulcanization adhesion or the like, or may be simply covered with the outer peripheral surface of the collision mass 30 without adhesion. .
[0044]
  In this example, the layer of the rubber elastic body 32 is provided so as to cover the outer peripheral surface of the collision mass 30, but may be provided so as to cover the inner peripheral surface of the idle chamber 28 in some cases.
[0045]
  As shown in FIG. 4C, in this example, a predetermined gap (d + d = 2d) between the layer of the rubber elastic body 32 that covers the outer peripheral surface of the collision mass 30 and the idler chamber 28. The same applies to the embodiment), and the collision mass 30 can move freely in the free space, that is, the free movement in the vibration direction of the wall 20 within the range allowed by the gap. In this example, the vibration direction of the wall 12 is the direction indicated by P in FIG.
[0046]
  As shown in FIG. 4, the housing 25 is also provided with a retaining portion 34 that prevents the collision mass 30 from coming out from both ends of the floating chamber 28.
[0047]
  In the case of the vibration damping device 22 of this example, when the wall 12 begins to vibrate in the P direction, the housing 25 is displaced integrally therewith and begins to vibrate in the P direction in synchronization with the wall 12. Since it is free to move independently in the vibration direction (P direction) with respect to the housing 25, the collision mass 30 collides with the housing 25 in the vibration direction when the housing 25 vibrates. It acts to cancel the vibration of the wall 12.
[0048]
  At this time, kinetic energy is given to the collision mass 30 from the housing 25 in the opposite direction, and the collision mass 30 moves in the opposite direction. Then, it collides again with the contact surface at a position opposite to the first contact surface and acts to cancel the vibration of the wall 12.
[0049]
  Thereafter, the collision mass 30 repeats the same movement in the opposite phase to that of the housing 25, absorbs the vibration energy of the housing 25 every time the collision occurs, and converts it into its own kinetic energy. As a result, the vibration energy of the wall 12 is attenuated by the energy absorption by the sliding friction at that time, and the vibration is effectively suppressed.
[0050]
  In the vibration damping device 22 of this example, since the rubber elastic body 32 layer is formed on the outer peripheral surface of the collision mass 30, there is no problem that a large noise is generated at the time of collision. The vibration energy is converted and absorbed into heat by the viscous behavior, and this also makes the vibration damping of the wall 12 more effective.
[0051]
  As described above, the vibration damping device 22 of the present example is provided with the collision mass 30 so as to be independently movable, and moves it in an opposite phase to the wall 12 to be damped to absorb and attenuate vibration energy. There is no particular frequency dependence, vibration can be suppressed over a wide frequency range, and it is easy and simple to take a collision direction in multiple directions, and multidirectional vibration can be suppressed, In addition, the dependence on temperature is small, and a good damping effect is exhibited over a wide temperature range from high to low.
[0052]
  Further, since the required mass of the collision mass 30 is light and sufficient, the required space of the entire apparatus is small and compact, and various features such as easy mounting on the wall 12 are provided.
  Furthermore, the vibration damping device of this example has an advantage that it can be easily attached to an existing wall by retrofitting.
[0053]
  FIG.OtherofreferenceAn example is shown.
  In this example, the entire housing 25 of the vibration damping device 22 is configured with the construction material of the wall 12.
  Specifically, the frame member 36 is disposed vertically across the skeleton members 18 and 18 at a predetermined interval, so that the frame 25, the skeleton member 18, and the pair of surface members 20, 23 can serve as a housing 25. The collision mass 30 is movably accommodated inside the floating chamber 28 having a rectangular cross section inside.
[0054]
  Even in this case, a gap is secured between the layer of the rubber elastic body 32 covering the outer peripheral surface of the collision mass 30 and the inner surface of the idler chamber 28, particularly the vertical inner surface, so that the collision mass 30 can freely move back and forth. It is.
  5B is an example in which a spherical mass is used as the collision mass 30, and in the example of FIG. 5C, a collision mass having a rectangular shape in both the transverse and vertical sections is used as the collision mass 30. It is an example.
  According to this example, the number of members required for the soundproof wall configuration can be reduced, and the structure can be further simplified.
[0055]
  The example of FIG. 6 is also an example in which the entire housing 25 of the vibration damping device 22 is configured with the construction material of the wall 12.
  In this example, a pair of surface materials 20 and 23 and a skeleton member 18 on the wall 12 constitute a housing 25 and a floating chamber 28 is formed inside thereof. Then, a plate-like floating mass 30 having a vertically long shape is accommodated in the floating chamber 28 in a state where a rubber elastic body 32 layer is formed on the outer peripheral surface thereof.
[0056]
  Also in this example, a gap for ensuring free movement of the collision mass 30 is ensured between the layer of the rubber elastic body 32 and the idler chamber 28, particularly in the front-rear direction, specifically in the direction perpendicular to the plate surface of the wall 12. Yes.
[0057]
  As shown in the drawing, in this example, the damping device 22 is provided over almost the entire wall 12. In other words, almost the entire wall 12 is configured as the vibration damping device 22.
[0058]
  FIG. 7 shows an example in which the door 14 in FIG. 2 is configured as a soundproof door.
  As shown in the figure, in this example, the firstreferenceIn the same manner as in the example, a vibration damping device 22 is attached to the inside of the door 14 and the back surface of the surface material 20, thereby damping the door 14.
  In FIG. 7, reference numeral 38 denotes a handle provided on the surface material 23.
[0059]
  In this way, by applying the vibration damping device 22 of this example to the door 14 serving as the wall of the opening of the entrance / exit, it is possible to prevent the generation of noise and the transmission of sound due to the vibration of the door 14.
[0060]
  8 and 9 show an example in which the ceiling 16 in FIG. 2 is a soundproof ceiling.
  In these drawings, reference numeral 42 denotes a surface material (ceiling material), and 44 and 46 denote field edges and field edges as frame members, respectively.
  In this example, the vibration damping device 22 is attached to the respective back surfaces (upper surfaces) of the surface material 42, the field edge 44 and the field edge receiver 46 at the positions A, B, and C in FIG. However, these are merely examples of attachment positions, and it is of course possible to attach the vibration damping device 22 only at any one or two places or at another place.
[0061]
  In addition, the thing of the form similar to what was shown in the said FIG. 4 is used as the damping device 22 of this example. Of course, other types of vibration control devices can be used. This point is the previousreferenceExamples and examples belowAnd referenceThe same applies to the examples.
[0062]
  Even when the vibration damping device 22 of this example is mounted on the ceiling 16 of the house, the vibration damping device 22 is applied to the wall 12 described above.ExampleTherefore, the same excellent damping effect as that described above is obtained.
[0063]
  FIG. 10 shows another example. Here, a casing 47 having a substantially U-shaped cross section is attached to the back side of the surface material 42 on the ceiling 16, and the casing 25 and a part of the surface material 42 are used for the housing 25. The collision mass 30 is accommodated in a floating state together with a layer of a rubber elastic body 32 covering the outer peripheral surface thereof in a floating chamber 28 inside.
  By doing in this way, the number of members required for a soundproof ceiling structure can be reduced, and a structure can be simplified more.
[0064]
  Next, FIGS. 11 and 12 show the present invention.The fruitAn example is shown.
  This example is also an example in the case where the ceiling 16 is a soundproof ceiling, and as shown in the drawing, the field receiver 46 is made of C-type steel, and a metal casing whose one surface has an open shape. As shown in FIG. 12, the housing 25 is constituted by a part of the field receiver 46 made of the C-shaped steel and the casing 48 by fixing 48 with the screw fixture 40.
[0065]
  A rectangular parallelepiped collision mass 30 is movably accommodated inside the idle chamber 28 formed inside thereof. The point that the outer peripheral surface of the collision mass 30 is covered with the layer of the rubber elastic body 32 is the same as in the above embodiments.
[0066]

A rectangular parallelepiped collision mass 30 is accommodated in an idle state in a state where the collision mass 30 is covered with a rubber elastic body 32 layer.
  It is also possible to apply the embodiment of FIG. 13 to a field reception.
  Also in the case of this example, the number of members required for the soundproof ceiling configuration can be reduced, and the structure can be further simplified.
[0067]
  FIG.OtherofreferenceAn example is shown.

  As shown in the figure, in this example, the vibration damping device 22 is attached to the back side of the roof 52, and the roof 52 is made a soundproof roof by the vibration damping effect.
  In FIG. 14, 54 is a skeleton member in the roof 52, and 56 is a face material.
[0068]
  Even when the vibration damping device 22 is mounted on the roof 52 of the house in this manner, the vibration damping device 22 exhibits a vibration damping effect by the same action as described above, and the roof 52 is favorably suppressed from vibration.
[0069]
  FIG. 15 shows an example in which most of the housing 25 of the vibration damping device 22 is configured by a roof construction material when the roof 52 is a soundproof roof.
