Summary of the Invention

Problems to be Solved by the Invention

[0004] In the floor vibration damping system disclosed in Patent Document 1, it is necessary to install a device for suppressing the vibration of a building. It is desirable that a member for suppressing the vibration of a building can be installed more easily.

Means for Solving the Problems

[0005] (1) The vibration damping member for solving the above problems is a vibration damping member configured to suppress the vibration of a second body in a building including a first body and a second body connected to the first body, the vibration damping member including a damping member disposed between the first body and the second body, and an engaging member for engaging the first body and the second body, the engaging member being fixed to one of the first body and the second body and engaging with the other of the first body and the second body so as to be relatively movable.

[0006] According to this configuration, the second body can move relative to the first body. Therefore, when the second body vibrates, the vibration of the second body can be absorbed by the damping member. By arranging the vibration suppression member on the building body in this way, a structure for suppressing the vibration of the second body can be installed more simply.

[0007] (2) In the vibration suppression member according to (1) above, the engaging member has a fixing portion fixed to one of the first body and the second body, and an engaging portion that engages so as to be relatively movable with the other of the first body and the second body, and the damping member is disposed between the fixing portion and the body that engages with the engaging portion among the first body and the second body.

[0008] According to this configuration, the damping member can be arranged so that the damping member can be preferably deformed by the vibration of the second body.

[0009] (3) In the vibration suppression member according to (2) above, the body that the engaging portion engages with among the first body and the second body is defined as the engaged body, a long hole extending in the vertical direction is formed in the engaging portion, and a pin member fixed to the engaged body is inserted through the long hole.

[0010] According to this configuration, the engaged body can move relative to the engaging member in the vertical direction in which the long hole extends.

[0011] (4) The vibration damping member for solving the above problems is a vibration damping member configured to suppress the vibration of a second housing in a building including a first housing and a second housing connected to the first housing. The vibration damping member includes a damping member disposed between the first housing and the second housing, an intermediate member disposed between the first housing and the second housing, a first engaging member that engages the first housing and the intermediate member, and a second engaging member that engages the second housing and the intermediate member. The first engaging member has a first fixing portion fixed to one of the first housing and the intermediate member, and a first engaging portion that engages relatively movably with the other of the first housing and the intermediate member. The second engaging member has a second fixing portion fixed to one of the second housing and the intermediate member, and a second engaging portion that engages relatively movably with the other of the second housing and the intermediate member. The damping member has a first damping member and a second damping member. The first damping member is disposed between the first fixing portion and an object that engages with the first engaging portion among the first housing and the intermediate member. The second damping member is disposed between the second fixing portion and an object that engages with the second engaging portion among the second housing and the intermediate member.

[0012] According to this configuration, the second housing can move relative to the first housing. Therefore, when the second housing vibrates, the vibration of the second housing can be absorbed by the damping member. By disposing the vibration damping member on the housing of the building in this way, a structure for suppressing the vibration of the second housing can be installed more simply.

[0013] (5) In the vibration damping member according to (4) above, the object with which the first engaging portion among the first housing and the intermediate member engages is defined as a first engaged housing, and the object with which the second engaging portion among the second housing and the intermediate member engages is defined as a second engaged housing. A first elongated hole extending in the vertical direction is formed in the first engaging portion, and a first pin member fixed to the first engaged housing is inserted through the first elongated hole. A second elongated hole extending in the vertical direction is formed in the second engaging portion, and a second pin member fixed to the second engaged housing is inserted through the second elongated hole.

[0014] According to this configuration, the first engaged body can move relative to the first engaging member in the vertical direction in which the first long hole extends. Further, the second engaged body can move relative to the second engaging member in the vertical direction in which the second long hole extends.

[0015] (6) In the vibration damping member according to (1) above, the engaging member is configured with a long hole extending in the vertical direction, and a pin member interlocking with the body that can engage with the engaging member in a relatively movable manner among the first body and the second body is inserted into the long hole, and the damping member is arranged so as to surround at least a part of the engaging member.

[0016] According to this configuration, the body that can engage with the engaging member in a relatively movable manner among the first body and the second body can move relative to the engaging member in the vertical direction in which the long hole extends.

[0017] (7) A building that solves the above problems is a building having a building body, wherein the building body includes the first body, the second body, and the vibration damping member according to any one of (1) to (6) above, the first body is arranged at a position different from that of the second body in the vertical direction, and is configured to have higher rigidity than the second body, at least one of the first body and the second body has an extension portion extending toward the other, and the first body and the second body are connected via the extension portion and the vibration damping member.

[0018] According to this configuration, the second body is connected to the first body via the extension portion and the vibration damping member. Since the rigidity of the first body is higher than that of the second body, the vibration of the second body can be preferably attenuated by the vibration damping member.

[0019] (8) In the building according to (7) above, the building body further includes a truss structure gable frame, and the first body is configured as at least a part of the gable frame.

[0020] According to this configuration, since the first body is configured as at least a part of the gable frame having a truss structure, the rigidity of the first body can be further improved.

[0021] (9) The building that solves the above problems is a building having a building main body, and the building main body includes a first body, a second body, and a vibration suppression member that suppresses the vibration of the second body. The first body is arranged at a position different from that of the second body in the vertical direction and is configured to have higher rigidity than the second body. At least one of the first body and the second body has an extension portion extending toward the other, and the first body and the second body are connected via the extension portion and the vibration suppression member.

[0022] According to this configuration, the second body is connected to the first body via the extension portion and the vibration suppression member. Since the rigidity of the first body is higher than that of the second body, the vibration suppression member can preferably attenuate the vibration of the second body. By arranging the vibration suppression member between the first body and the second body in this way, a floor vibration suppression system can be configured, so that a structure for suppressing the vibration of the second body can be installed more simply.

[0023] (10) In the building according to any one of (7) to (9) above, the building main body includes an outer body and an inner body arranged inside the outer body. The outer body has a framed structure and an outer support portion that supports the framed structure. The inner body has a ceiling including the first body, a floor structure including the second body, and an inner support portion that supports the ceiling and the floor structure. The ceiling is connected to the framed structure via a connecting portion.

[0024] According to this configuration, since the framed structure is supported by the outer support portion, the vibration of the floor arranged in the inner body is less likely to be transmitted to the framed structure of the outer body. By suppressing the vibration transmitted to the framed structure from other than the connecting portion, the vibration suppression member can effectively attenuate the vibration transmitted from the connecting portion to the framed structure. Thereby, the vibration suppression member can effectively suppress the vibration of the second body.

Advantages of the Invention

[0025] The vibration suppression member and the building of the present disclosure can more easily install a member for suppressing the vibration of the building.

Modes for Carrying Out the Invention

[0027] <First Embodiment> With reference to FIGS. 1 to 5, the vibration suppression member 30 and the building 10 according to the present embodiment will be described.

[0028] <Building> As shown in FIG. 1, an example of the building 10 is a detached house. The building 10 has a building main body 11. FIG. 1 illustrates a two-story building main body 11.

[0029] <Building main body> As shown in FIGS. 1 and 2, the building main body 11 includes a roof truss 12. The roof truss 12 includes ridge beams 12A, slope beams 12B, and roof purlins 12C. In one example, a ceiling 13 is formed under the roof truss 12. The ceiling 13 is arranged, for example, on the second floor of the building main body 11.

[0030] The roof truss 12 of the present embodiment has a truss structure 14. The truss structure 14 is formed, for example, on a surface surrounded by two slope beams 12B and one roof purlin 12C in a front view. The truss structure 14 is formed, for example, by combining a plurality of truss members 13B around a column bundle 13A. The plurality of truss members 13B include vertical members and diagonal members. In the truss structure 14, the arrangement of the column bundle 13A and the plurality of truss members 13B is set according to the rigidity of the roof truss 12. Note that in FIG. 1, the plurality of truss members 13B are omitted.

[0031] The building main body 11 has a floor structure 15. The floor structure 15 of the present embodiment supports the floor on the second floor of the building main body 11. The floor structure 15 includes floor beams 15A. The floor on the second floor of the building main body 11 is formed by arranging floor materials on the floor beams 15A. The building main body 11 has columns 16 that support the roof truss 12 and the floor structure 15.

[0032] The building main body 11 includes a building frame 20. The building frame 20 is configured as a framework that supports the building main body 11. The building frame 20 includes a first building frame 21 and a second building frame 22. The first building frame 21 is arranged at a different position from the second building frame 22 in the vertical direction. The first building frame 21 is arranged, for example, above the second building frame 22.

[0033] The first building frame 21 of the present embodiment is configured as at least a part of the roof truss 12. The first building frame 21 includes, for example, at least the roof purlins 12C. The first building frame 21 is, for example, the roof truss 12. The second building frame 22 of the present embodiment is configured as at least a part of the floor structure 15. The second building frame 22 includes, for example, at least the floor beams 15A.

[0034] The first body 21 is configured to have higher rigidity than the second body 22. For example, the thickness, number, arrangement, material, etc. of the members constituting the body 20 are designed so that the rigidity of the first body 21 is higher than that of the second body 22. Since the first body 21 has higher rigidity than the second body 22, it is less likely to bend than the second body 22. In one example, the frame structure 12, which is the first body 21, has a truss structure 14, so the rigidity is improved compared to the case where it does not have the truss structure 14.

[0035] At least one of the first body 21 and the second body 22 has an extension part 23 extending toward the other. In the present embodiment, the first body 21 has the extension part 23. The extension part 23 extends from the first body 21 toward the second body 22. The extension part 23 is connected to, for example, the roof beam 12C of the frame structure 12. The extension part 23 extends, for example, from the roof beam 12C toward the floor beam 15A of the floor structure 15.

[0036] The second body 22 is connected to the first body 21. The second body 22 is indirectly connected to the first body 21 via, for example, the extension part 23 and the vibration damping member 30. The extension part 23 is configured as a support column connecting the first body 21 and the second body 22 in the vertical direction, for example. The extension part 23 is made of wood. The extension part 23 may be made of materials such as metal and resin. The extension part 23 may be arranged to be exposed on the second floor of the building body 11, or may be arranged inside the wall partitioning the second floor of the building body 11.

[0037] The building body 11 includes the first body 21, the second body 22, and the vibration damping member 30. The first body 21 and the second body 22 are connected via the extension part 23 and the vibration damping member 30. The vibration damping member 30 connects the extension part 23 and the second body 22.

[0038] In FIG. 1, three purlins 12C are illustrated, but the number of purlins 12C may be two or four or more. Similarly, in FIG. 1, three floor beams 15A are illustrated, but the number of floor beams 15A may be two or four or more. Further, in FIG. 1, one extension part 23 is illustrated, but two or more extension parts 23 may be provided.

[0039] As shown in FIG. 3, a groove part 23G is provided in the extension part 23. The groove part 23G is provided on the surface of the extension part 23 of the first housing body 21 that faces the second housing body 22. A vibration damping member 30 is arranged in the groove part 23G.

[0040] <Vibration damping member> As shown in FIGS. 2 and 3, the vibration damping member 30 is configured to suppress the vibration of the second housing body 22 in the building 10 including the first housing body 21 and the second housing body 22. The vibration damping member 30 includes a damping member 31 and an engagement member 32. The vibration of the second housing body 22 in the building 10 is suppressed by the damping member 31 absorbing the vibration of the second housing body 22.

[0041] <Engagement member> The engagement member 32 engages the first housing body 21 and the second housing body 22. The engagement member 32 is fixed to one of the first housing body 21 and the second housing body 22 and engages with the other of the first housing body 21 and the second housing body 22 so as to be relatively movable. In the present embodiment, the engagement member 32 is fixed to the second housing body 22 and engages with the first housing body 21 so as to be relatively movable, whereby the first housing body 21 and the second housing body 22 are engaged. The engagement member 32 is fixed to the floor beam 15A of the floor assembly 15. The engagement member 32 engages with the purlin assembly 12 via the extension part 23 so as to be relatively movable.

[0042] The engagement member 32 has a fixing part 33 fixed to one of the first housing body 21 and the second housing body 22 and an engagement part 34 that engages with the other of the first housing body 21 and the second housing body 22 so as to be relatively movable. The housing body 20 with which the engagement part 34 engages among the first housing body 21 and the second housing body 22 is defined as an engaged housing body 20A. In the present embodiment, the engaged housing body 20A is the first housing body 21.

[0043] The fixing part 33 is fixed to the second body 22. An example of the fixing part 33 is a tenon pipe. A hole 22H into which the fixing part 33 is inserted is provided on the upper surface of the second body 22.

[0044] A fixing hole 33H is formed in the fixing part 33. The fixing pin member 35 fixed to the second body 22 is inserted through the fixing hole 33H. The fixing pin member 35 is fixed to the second body 22 by inserting through a through hole provided in the second body 22. The fixing pin member 35 is, for example, a drift pin.

[0045] The engaging part 34 engages with the first body 21 so as to be relatively movable. Specifically, the engaging member 32 engages with the extension part 23 so as to be relatively movable in the vertical direction with respect to the first body 21. The engaging part 34 has, for example, two support plates 34A arranged along the groove part 23G of the extension part 23, and a fixing plate 34B for fixing the two support plates 34A to the fixing part 33.

[0046] An elongated hole 34H extending in the vertical direction is formed in the engaging part 34. The elongated hole 34H is provided in the two support plates 34A. A pin member 36 fixed to the engaged body 20A is inserted through the elongated hole 34H. The pin member 36 is fixed to the first body 21 by inserting through a through hole provided in the first body 21.

[0047] The fixing plate 34B is connected to the fixing part 33 by welding or the like, for example. The two support plates 34A are attached to the fixing plate 34B so as to extend upward from the fixing plate 34B. The engaging part 34 may be formed by pressing one metal plate.

[0048] As shown in FIGS. 4 and 5, the fixing plate 34B is arranged at a position separated from the second body 22 by a distance D1 when the fixing part 33 is fixed to the second body 22. The distance D1 is set according to the amount of movement of the second body 22 with respect to the first body 21 when the second body 22 vibrates.

[0049] Between the two support plates 34A, an arrangement portion 37 for arranging the damping member 31 is formed. The arrangement portion 37 is formed with a pressing surface 37A that presses the damping member 31 toward the bottom surface BS of the groove portion 23G in the vertical direction. The pressing surface 37A is formed on the surface of the fixed plate 34B facing the first housing 21. When the second housing 22 moves upward, the pressing surface 37A moves toward the bottom surface BS of the groove portion 23G as the fixed plate 34B moves upward together with the fixing portion 33 fixed to the second housing 22.

[0050] <Damping member> As shown in FIG. 3, the damping member 31 is disposed between the first housing 21 and the second housing 22. The damping member 31 may be disposed between the first housing 21 and the second housing 22 so as not to receive a load from the first housing 21 in the normal state. The normal state indicates a state where the second housing 22 does not vibrate. The damping member 31 deforms in response to the relative movement between the first housing 21 and the second housing 22 in the vertical direction. Examples of the damping member 31 are viscoelastic materials such as rubber or elastic materials such as springs.

[0051] As shown in FIGS. 4 and 5, the damping member 31 of the present embodiment is located in the groove portion 23G of the extension portion 23. The damping member 31 is formed with an insertion hole 31H. In a front view, the insertion hole 31H overlaps with the long hole 34H of the engaging portion 34. The pin member 36 that passes through the long hole 34H passes through the insertion hole 31H of the damping member 31, whereby the damping member 31 is positioned in the groove portion 23G of the extension portion 23. The insertion hole 31H is, for example, a round hole. The insertion hole 31H may be a long hole extending in the vertical direction.

[0052] The damping member 31 is disposed between the fixing portion 33 of the engaging member 32 and the engaged body 20A. The damping member 31 of the present embodiment is disposed between the fixing portion 33 and the first body 21. By being disposed in the disposing portion 37 of the engaging portion 34, the damping member 31 is disposed in the groove portion 23G of the extending portion 23. The damping member 31 is in contact with the bottom surface BS of the groove portion 23G and the pressing surface 37A of the engaging portion 34. The damping member 31 is disposed, for example, along the engaging member 32. Specifically, the damping member 31 is disposed along the support plate 34A of the engaging portion 34 in the vertical direction.

[0053] <Operation of the Embodiment> The first operation of the present embodiment will be described. Since the engaging member 32 is engaged with the first body 21 so as to be relatively movable and is fixed to the second body 22, when the second body 22 vibrates, the second body 22 repeats relative movement with respect to the first body 21. Since the damping member 31 is disposed between the first body 21 and the second body 22, the damping member 31 deforms according to the relative movement between the first body 21 and the second body 22. The damping member 31 absorbs the vibration of the second body 22. As a result, for example, even if vibration occurs on the floor of the building 10 constituted by the floor structure 15 which is the second body 22 due to the walking of the occupant, the damping member 31 can absorb the vibration.

[0054] The second operation of the present embodiment will be described. Since the first body 21 is relatively movable with respect to the second body 22, even if the first body 21 is deformed due to aging or the like, the deformation of the first body 21 is less likely to be transmitted to the second body 22. For this reason, in the building 10, even if the frame structure 12 included in the first body 21 is bent, the bending is less likely to be transmitted to the floor structure 15 included in the second body 22. In this way, it is possible to suppress the load of the frame structure 12 which is the first body 21 from being applied to the floor structure 15 which is the second body 22.

[0055] The third operation of the present embodiment will be described. The fixing portion 33 of the engaging member 32 can be constituted by a tenon pipe. The engaging portion 34 of the engaging member 32 can be constituted by one or a plurality of plates. Further, the vibration suppressing member 30 can be installed on the housing 20 by a support column such as the extension portion 23. Therefore, compared with a large-scale device such as a TMD (tuned mass damper) known as a conventional floor vibration control system, the space required for installing the vibration suppressing member 30 is reduced.

[0056] The fourth operation of this embodiment will be described. When constructing a large floor in a building, a beam with a large span may be used. In addition, when installing a skeleton staircase, a beam with a large span may be used on the upper floor. When the span of the beam increases, the floor beam is likely to vibrate due to human walking or the like, and there is a risk that the occupants will feel uncomfortable. According to the vibration suppressing member 30, a floor vibration control system can be easily installed, so that the degree of freedom in the design of the building 10 can be improved.

[0057] The fifth operation of this embodiment will be described. After removing the pin member 36, by sliding the damping member 31 from the placement portion 37, the damping member 31 can be removed from the groove portion 23G without removing the engaging member 32 from the first housing 21 and the second housing 22. Therefore, for example, after the construction of the building 10, the tuning of the damping member 31 can be easily performed.

[0058] The sixth operation of this embodiment will be described. The rigidity of the first housing 21 is higher than the rigidity of the second housing 22. Therefore, when the damping member 31 of the vibration suppressing member 30 is deformed, the difference in the amount of deformation between the first housing 21 and the second housing 22 is absorbed. The higher the rigidity of the first housing 21 is than the rigidity of the second housing 22, the more suitably the vibration suppressing member 30 can absorb vibration.

[0059] <Effects of the Embodiment> The effects of this embodiment will be described. (1-1) The vibration damping member 30 includes a damping member 31 and an engagement member 32. The damping member 31 is disposed between the first housing 21 and the second housing 22. The engagement member 32 is fixed to one of the first housing 21 and the second housing 22 and is engaged with the other of the first housing 21 and the second housing 22 so as to be relatively movable.

[0060] According to this configuration, the second housing 22 can move relative to the first housing 21. Therefore, when the second housing 22 vibrates, the vibration of the second housing 22 can be absorbed by the damping member 31. By disposing the vibration damping member 30 on the housing 20 of the building 10 in this way, a structure for suppressing the vibration of the second housing 22 can be installed more easily.

[0061] Since the first housing 21 and the second housing 22 are engaged by the engagement member 32, when the second housing 22 vibrates, the displacement of the second housing 22 from the first housing 21 is suppressed. Therefore, the vibration of the second housing 22 can be preferably transmitted to the first housing 21.

[0062] (1-2) The engagement member 32 includes a fixing portion 33 fixed to one of the first housing 21 and the second housing 22 and an engagement portion 34 engaged with the other of the first housing 21 and the second housing 22 so as to be relatively movable. The damping member 31 is disposed between the fixing portion 33 and the housing 20 that engages with the engagement portion 34 among the first housing 21 and the second housing 22.

[0063] According to this configuration, the damping member 31 can be disposed so that the damping member 31 can be preferably deformed by the vibration of the second housing 22.

[0064] (1-3) A long hole 34H extending in the vertical direction is formed in the engagement portion 34. A pin member 36 fixed to the engaged housing 20A is inserted into the long hole 34H.

[0065] According to this configuration, the engaged housing 20A can move relative to the engagement member 32 in the vertical direction in which the long hole 34H extends.

[0066] (1-4) The building main body 11 includes a first body 21, a second body 22, and a vibration suppression member 30. The first body 21 is arranged at a position different from that of the second body 22 in the vertical direction. The first body 21 is configured to have higher rigidity than the second body 22. The first body 21 and the second body 22 are connected via an extension part 23 and the vibration suppression member 30.

[0067] According to this configuration, the second body 22 is connected to the first body 21 via the extension part 23 and the vibration suppression member 30. Since the rigidity of the first body 21 is higher than that of the second body 22, the vibration suppression member 30 can preferably attenuate the vibration of the second body 22.

[0068] (1-5) The building main body 11 further includes a framed structure 12 having a truss structure 14. The first body 21 is configured as at least a part of the framed structure 12.

[0069] According to this configuration, since the first body 21 is configured as at least a part of the framed structure 12 having the truss structure 14, the rigidity of the first body 21 can be further improved.

[0070] (1-6) The building main body 11 includes a first body 21, a second body 22, and a vibration suppression member 30. The first body 21 is arranged at a position different from that of the second body 22 in the vertical direction. The first body 21 is configured to have higher rigidity than the second body 22. At least one of the first body 21 and the second body 22 has an extension part 23 extending toward the other. The first body 21 and the second body 22 are connected via the extension part 23 and the vibration suppression member 30. The vibration suppression member 30 suppresses the vibration of the second body 22.

[0071] According to this configuration, the second body 22 is connected to the first body 21 via the extension part 23 and the vibration damping member 30. Since the rigidity of the first body 21 is higher than that of the second body 22, the vibration damping member 30 can preferably attenuate the vibration of the second body 22. By arranging the vibration damping member 30 between the first body 21 and the second body 22 in this way, a floor vibration damping system can be configured, so that a structure for suppressing the vibration of the second body 22 can be installed more simply.

[0072] <Second Embodiment> Referring to FIG. 6, the building 10 and the vibration damping member 30 according to the second embodiment will be described. In this embodiment, for the components that are substantially the same as those in the first embodiment, the same reference numerals as those in the first embodiment are used, and the description thereof is omitted.

The first damping member 41A is disposed between the first fixing portion 51 and the first engaged housing 24A. The second damping member 41B is disposed between the second fixing portion 61 and the second engaged housing 24B.

[0084] <Function of the Embodiment> The function of this embodiment will be described. In this embodiment, since the damping member 41 has the first damping member 41A and the second damping member 41B, the volume of the damping member 41 becomes large. Therefore, the vibration damping effect by the damping member 41 can be improved.

[0085] <Effect of the Embodiment> The effect of this embodiment will be described. (2-1) The vibration suppression member 30 includes a damping member 41, an intermediate body 42, a first engagement member 50, and a second engagement member 60. The first engagement member 50 has a first fixing portion 51 fixed to one of the first housing 21 and the intermediate body 42, and a first engagement portion 52 that engages with the other of the first housing 21 and the intermediate body 42 so as to be relatively movable.

The second damping member 41B is disposed between the second fixing portion 61 and an object that engages with the second engagement portion 62 among the second housing 22 and the intermediate body 42.

[0086] According to this configuration, the second housing 22 can move relative to the first housing 21. Therefore, when the second housing 22 vibrates, the vibration of the second housing 22 can be absorbed by the damping member 41. By disposing the vibration suppression member 30 on the housing 20 of the building 10 in this way, a structure for suppressing the vibration of the second housing 22 can be installed more simply.

[0087] (2-2) A first engaging portion 52 is formed with a first long hole 52H extending in the vertical direction. A first pin member 54 fixed to the first engaged body 24A is inserted through the first long hole 52H. A second engaging portion 62 is formed with a second long hole 62H extending in the vertical direction. A second pin member 64 fixed to the second engaged body 24B is inserted through the second long hole 62H.

[0088] According to this configuration, the first engaged body 24A can move relative to the first engaging member 50 in the vertical direction in which the first long hole 52H extends. Also, the second engaged body 24B can move relative to the second engaging member 60 in the vertical direction in which the second long hole 62H extends.

[0089] <Third Embodiment> With reference to FIGS. 7 to 9, the building 10 and the vibration damping member 30 according to the third embodiment will be described. In this embodiment, for the configurations that are substantially the same as those of the first embodiment, the same reference numerals as those of the first embodiment are used, and the description thereof is omitted.

[0090] As shown in FIGS. 7 and 8, in this embodiment, an engaging member 32 is fixed to the first housing 21 and engages with the second housing 22 so as to be relatively movable, thereby engaging the first housing 21 and the second housing 22. The engaging member 32 of this embodiment includes a main body portion 70. An example of the main body portion 70 is a dovetail pipe. The main body portion 70 is inserted into a hole 21H provided in an extension portion 23 of the first housing 21 and is also inserted into a hole 22H provided in the second housing 22.

[0091] The engaging member 32 is formed with a fixing hole 71. The fixing hole 71 is provided in a portion of the main body portion 70 that is inserted into the hole 21H provided in the extension portion 23 of the first housing 21. A fixing pin member 72 fixed to the first housing 21 is inserted through the fixing hole 71. The fixing pin member 72 is fixed to the first housing 21 by inserting through a through hole provided in the first housing 21. The fixing pin member 72 is, for example, a drift pin.

[0092] The engaging member 32 is formed with a long hole 73 extending in the vertical direction. The long hole 73 is provided in a portion of the main body 70 that is inserted into the hole 22H provided in the second housing 22. A pin member 74 that interlocks with the housing 20 that engages with the engaging member 32 in a relatively movable manner among the first housing 21 and the second housing 22 is inserted through the long hole 73. The pin member 74 is fixed to the second housing 22 by passing through a through hole provided in the second housing 22.

[0093] The vibration damping member 30 includes a damping member 75. The damping member 75 is made of, for example, the same material as the damping member 31 of the first embodiment. The damping member 75 is arranged along the outer surface of the main body 70. The damping member 75 is arranged between the lower surface of the extension 23 of the first housing 21 and the upper surface of the second housing 22. The damping member 75 may be arranged between the first housing 21 and the second housing 22 so as not to receive a load from the first housing 21 in the normal state.

[0094] As shown in FIG. 9, the damping member 75 is arranged so as to surround at least a part of the engaging member 32. In plan view, the damping member 75 surrounds at least a part of the outer surface of the main body 70. The damping member 75 has a recess 76 in plan view. The engaging member 32 is located in the recess 76 of the damping member 75. An opening 76A is formed in the recess 76 of the damping member 75. The opening 76A is configured such that the damping member 75 can be removed from between the first housing 21 and the second housing 22 by moving the damping member 75 relative to the engaging member 32 so that the main body 70 passes through the opening 76A.

[0095] In one example, in plan view, the size of the opening 76A is set to be smaller than the diameter of the main body 70. For example, when the main body 70 passes through the opening 76A, the main body 70 passes through the opening 76A by the opening 76A deforming. The size of the opening 76A may be set to be equal to or larger than the diameter of the main body 70.

[0096] <Actions of the Embodiment> The first action of this embodiment will be described. Since the main body 70 of the engaging member 32 can be constituted by a tenon pipe, the vibration damping member 30 of the present embodiment is excellent in manufacturing cost.

[0097] The second operation of the present embodiment will be described. Due to the opening 76A, the damping member 75 can be removed in a state where the first housing 21 and the second housing 22 are engaged by the engaging member 32. Therefore, for example, tuning of the damping member 31 can be easily performed after the construction of the building 10.

[0098] <Effect of the embodiment> The effect of the present embodiment will be described. The engaging member 32 is formed with a long hole 73 extending in the vertical direction. A pin member 74 interlocking with the housing 20 that is engaged with the engaging member 32 so as to be relatively movable among the first housing 21 and the second housing 22 is inserted through the long hole 73. The damping member 75 is disposed so as to surround at least a part of the engaging member 32.

[0099] According to this configuration, the housing 20 that is engaged with the engaging member 32 so as to be relatively movable among the first housing 21 and the second housing 22 can move relative to the engaging member 32 in the vertical direction in which the long hole 73 extends.

[0100] <Fourth Embodiment> With reference to FIG. 10, the building 10 and the vibration damping member 30 according to the fourth embodiment will be described. In the present embodiment, for the configurations that are substantially the same as those of the first embodiment, the same reference numerals as those of the first embodiment are given, and the description thereof is omitted.

[0101] As shown in FIG. 10, the building body 11 of the present embodiment includes an outer housing 80 and an inner housing 90. The inner housing 90 is disposed inside the outer housing 80. The outer housing 80 and the inner housing 90 are configured as a framework for supporting the building body 11.

[0102] The outer body 80 has a framework 81 and an outer support portion 82. The outer support portion 82 supports the framework 81. The outer support portion 82 includes, for example, a column 83 that supports the framework 81. The framework 81 is configured, for example, in accordance with the framework 12 of the first embodiment. The framework 81 may have a truss structure 14.

[0103] The inner body 90 has a ceiling 91, a floor assembly 92, and an inner support portion 93. The inner support portion 93 supports the ceiling 91 and the floor assembly 92. The ceiling 91 is constituted by, for example, a ceiling beam 91A and a ceiling board disposed below the ceiling beam 91A. The floor assembly 92 is configured, for example, in accordance with the floor assembly 15 of the first embodiment. The inner support portion 93 includes, for example, a column 94 that supports the ceiling 91 and the floor assembly 92.

[0104] The building body 11 of the present embodiment further includes a connection portion 100. The connection portion 100 connects the outer body 80 and the inner body 90. Preferably, the inner body 90 is configured not to be connected to the outer body 80 except at the connection portion 100. The connection portion 100 is constituted by, for example, wood.

[0105] The ceiling 91 of the present embodiment is connected to the framework 81 via the connection portion 100. Specifically, the ceiling 91 is connected to the framework 81 by connecting a connection portion 100 extending from a roof beam 81A of the framework 81 to the ceiling beam 91A of the ceiling 91.

[0106] The ceiling 91 includes a first body 21. The first body 21 of the present embodiment includes, for example, the ceiling beam 91A of the ceiling 91. The first body 21 may include the outer body 80, the connection portion 100, and the ceiling beam 91A. The first body 21 may include the framework 81, the connection portion 100, and the ceiling beam 91A. The first body 21 of the present embodiment is supported by the column 94 of the inner body 90 and the connection portion 100.

[0107] The floor assembly 92 includes a second body 22. The second body 22 of the present embodiment includes, for example, a floor beam 92A that constitutes the floor assembly 92. The second body 22 of the present embodiment is supported by the inner body 90.

[0108] <Operation of the Embodiment> The operation of this embodiment will be described. Since the outer housing 80 and the inner housing 90 are connected only through the connection portion 100, vibrations generated on the floor of the inner housing 90 are less likely to be transmitted to the outer housing 80. Even if the second housing 22 included in the inner housing 90 vibrates, a decrease in the rigidity of the outer housing 80 is suppressed. As a result, it is easy to maintain the rigidity of the first housing 21 higher than that of the second housing 22.

[0109] <Effect of the Embodiment> The effect of this embodiment will be described. The building body 11 further includes an outer housing 80 and an inner housing 90 disposed within the outer housing 80. The outer housing 80 has a frame structure 81 and an outer support portion 82 that supports the frame structure 81. The inner housing 90 has a ceiling 91 including the first housing 21, a floor structure 92 including the second housing 22, and an inner support portion 93 that supports the ceiling 91 and the floor structure 92. The ceiling 91 is connected to the frame structure 81 via a connection portion 100.

[0110] According to this configuration, since the frame structure 81 is supported by the outer support portion 82, vibrations of the floor disposed in the inner housing 90 are less likely to be transmitted to the frame structure 81 of the outer housing 80. By suppressing vibrations transmitted to the frame structure 81 from other than the connection portion 100, the vibration suppression member 30 can effectively attenuate vibrations transmitted from the connection portion 100 to the frame structure 81. Thereby, the vibration suppression member 30 can effectively suppress vibrations of the second housing 22.

[0111] <Modification Example> The above embodiment is an example of the forms that the building 10 and the vibration suppression member 30 can take, and is not intended to limit that form. The building 10 and the vibration suppression member 30 can take forms different from those exemplified in the above embodiment. Examples thereof are forms in which a part of the configuration of the embodiment is replaced, changed, omitted, or forms in which a new configuration is added to the embodiment.

[0112] · As shown in FIG. 11, in the roof structure 12, a plurality of roof beams 12C may be arranged such that the pitch P1 between the roof beams 12C is 1 m or less. By arranging the roof beams 12C in this way, the number of roof beams 12C arranged in the roof structure 12 can be increased, so that the rigidity of the roof structure 12 can be improved. By improving the rigidity of the roof structure 12 which is the first body 21, the vibration of the second body 22 can be effectively suppressed.

[0113] · As shown in FIG. 12, the span S1 of the roof beam 12C may be shorter than the span S2 of the floor beam 15A. For example, the span S1 of the roof beam 12C is set to 5 / 6 or less of the span S2 of the floor beam 15A. When configured as in this modified example, the roof beam 12C may be arranged perpendicular to the floor beam 15A. By arranging the roof beam 12C in this way, the rigidity of the roof beam 12C which is the first body 21 can be made higher than the rigidity of the floor beam 15A which is the second body 22.

[0114] · The location where the extension part 23 and the vibration suppression member 30 are arranged is not limited to between the roof structure 12 and the floor structure 15.

In this modified example, in addition to the first body 21, the second body 22 may also have an extension part 23 extending toward the first body 21. The vibration suppression member 30 may be arranged between the extension part 23 of the first body 21 and the extension part 23 of the second body 22. Or, the extension part 23 of the first body 21 may be omitted, and the vibration suppression member 30 may be arranged between the first body 21 and the extension part 23 of the second body 22.

[0117] · The damping members 31, 41, 75 are not limited to viscoelastic materials such as rubber or elastic materials such as springs, and may be mechanically configured. Examples of the mechanically configured damping member 31 are devices such as hydraulic dampers, inertial mass dampers, magnetic dampers, and damping gears.

[0118] · In the first embodiment, the engaging member 32 may be fixed to the first housing 21 and engage with the second housing 22 so as to be relatively movable. In this modification, a groove in which the damping member 31 is disposed may be provided in the second housing 22.

[0119] · In the second embodiment, the first engaging member 50 may engage with the first housing 21 so as to be relatively movable and be fixed to the intermediate body 42. Also, the second engaging member 60 may engage with the second housing 22 so as to be relatively movable and be fixed to the intermediate body 42.

[0120] · In the second embodiment, an engaging member similar to the engaging member 32 of the third embodiment may be attached to at least one of the first end portion 43 and the second end portion 44 of the intermediate body 42.

[0121] · In the third embodiment, the engaging member 32 may engage with the first housing 21 so as to be relatively movable and be fixed to the second housing 22.

[0122] · In the third embodiment, the damping member 75 may be arranged in two parts. For example, in FIG. 8, one damping member 75 may be arranged in front of the paper surface of the engaging member 32, and one damping member 75 may be arranged behind the paper surface of the engaging member 32. In this modification, in a plan view, the entire outer surface of the main body portion 70 may be surrounded by the two damping members 75. Or the damping member 75 may be arranged in three or more parts.
