Summary of the Invention

Problems to be Solved by the Invention

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

Means for Solving the Problems

[0005] (1) The vibration suppression member for solving the above problems is a vibration suppression member configured to suppress the vibration of the second body in a building including a first body and a second body connected to the first body, the vibration suppression member comprising: a damping member disposed between the first body and the second body; and an engagement member that engages the first body and the second body, the engagement member being fixed to one of the first body and the second body and engaging relatively movably with the other of the first body and the second body.

[0006] In this configuration, the second structural frame can move relative to the first structural frame. Therefore, when the second structural frame vibrates, the vibration of the second structural frame can be absorbed by the damping member. By arranging vibration suppression members in the structural frame of the building in this way, it becomes easier to install a structure to suppress vibrations of the second structural frame.

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

[0008] With this configuration, the damping members can be positioned so that they deform appropriately due to vibrations of the second structural body.

[0009] (3) In the vibration suppression member described in (2) above, the structure to which the engaging portion engages among the first structure and the second structure is defined as the engaged structure, and the engaging portion is configured with an elongated hole extending in the vertical direction, and a pin member fixed to the engaged structure is inserted through the elongated hole.

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

[0011] (4) A vibration suppression member for solving the above problems is a vibration suppression member configured to suppress vibration of a second structural body in a building including a first structural body and a second structural body connected to the first structural body, comprising: a damping member disposed between the first structural body and the second structural body; an intermediate body disposed between the first structural body and the second structural body; a first engaging member for engaging the first structural body and the intermediate body; and a second engaging member for engaging the second structural body and the intermediate body, wherein the first engaging member comprises a first fixing portion fixed to one of the first structural body and the intermediate body, and the first structural body and the intermediate body The first engaging member has a first engaging portion that engages with the other body so as to be movable relative to it, and the second engaging member has a second fixing portion that is fixed to one of the second body and the intermediate body, and a second engaging portion that engages with the other body so as to be movable relative to it, and 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 among the first body and the intermediate body that engages with the first engaging portion, and the second damping member is disposed between the second fixing portion and an object among the second body and the intermediate body that engages with the second engaging portion.

[0012] In this configuration, the second structural frame can move relative to the first structural frame. Therefore, when the second structural frame vibrates, the vibration of the second structural frame can be absorbed by the damping member. By arranging vibration suppression members in the structural frame of the building in this way, it becomes easier to install a structure to suppress vibrations of the second structural frame.

[0013] (5) In the vibration suppression member described in (4) above, the object that the first engaging portion engages with among the first frame and the intermediate body is defined as the first engaged frame, and the object that the second engaging portion engages with among the second frame and the intermediate body is defined as the second engaged frame, the first engaging portion is configured with a first elongated hole extending in the vertical direction, and a first pin member fixed to the first engaged frame is inserted through the first elongated hole, the second engaging portion is configured with a second elongated hole extending in the vertical direction, and a second pin member fixed to the second engaged frame is inserted through the second elongated hole.

[0014] In this configuration, the first engaged body can move relative to the first engaging member in the vertical direction along which the first elongated hole extends. Furthermore, the second engaged body can move relative to the second engaging member in the vertical direction along which the second elongated hole extends.

[0015] (6) In the vibration suppression member described in (1) above, the engaging member is provided with an elongated hole extending in the vertical direction, and a pin member that is interlocked with the first and second structural members and engages with the engaging member so as to be movable relative to it is inserted through the elongated hole, and the damping member is arranged to surround at least a part of the engaging member.

[0016] In this configuration, the frame that engages with the engaging member in a manner that allows for relative movement between the first and second frames can move relative to the engaging member in the vertical direction along which the elongated hole extends.

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

[0018] In this configuration, the second structural body is connected to the first structural body via an extension and a vibration-damping member. Because the rigidity of the first structural body is higher than that of the second structural body, the vibration-damping member can effectively dampen the vibrations of the second structural body.

[0019] (8) In the building described in (7) above, the building body further comprises a roof structure having a truss structure, and the first frame is configured as at least a part of the roof structure.

[0020] With this configuration, the first structural frame is configured as at least part of a roof structure having a truss structure, thus improving the rigidity of the first structural frame.

[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 that extends 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 easily.

[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 difficult 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> Referring 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 single-family house. The building 10 has a building main body 11. FIG. 1 illustrates a two-story building main body 11.

[0029] <Building body> As shown in Figures 1 and 2, the building body 11 includes a roof truss 12. The roof truss 12 includes a ridge beam 12A, a sloping beam 12B, and roof beams 12C. In one example, a ceiling 13 is constructed below the roof truss 12. The ceiling 13 is located, for example, on the second floor of the building body 11.

[0030] The roof structure 12 of this embodiment has a truss structure 14. The truss structure 14 is composed of a surface enclosed by two sloping beams 12B and one roof beam 12C in a front view, for example. The truss structure 14 is composed of multiple truss members 13B combined around a column bundle 13A, for example. The multiple truss members 13B include vertical members and diagonal members. In the truss structure 14, the arrangement of the column bundle 13A and the multiple truss members 13B is set according to the rigidity of the roof structure 12. Note that the multiple truss members 13B are omitted in Figure 1.

[0031] The building structure 11 has a floor framing 15. In this embodiment, the floor framing 15 supports the second floor of the building structure 11. The floor framing 15 includes floor beams 15A. The second floor of the building structure 11 is formed by placing flooring material on top of the floor beams 15A. The building structure 11 has columns 16 that support the roof truss 12 and the floor framing 15.

[0032] The building body 11 comprises a structural frame 20. The structural frame 20 is configured as a framework that supports the building body 11. The structural frame 20 includes a first structural frame 21 and a second structural frame 22. The first structural frame 21 is positioned differently from the second structural frame 22 in the vertical direction. The first structural frame 21 is positioned, for example, on top of the second structural frame 22.

[0033] The first structural frame 21 of this embodiment is configured as at least a part of the roof truss 12. The first structural frame 21 includes, for example, at least a roof beam 12C. The first structural frame 21 is, for example, the roof truss 12. The second structural frame 22 of this embodiment is configured as at least a part of the floor truss 15. The second structural frame 22 includes, for example, at least a floor beam 15A.

[0034] The first structural frame 21 is constructed to have higher rigidity than the second structural frame 22. For example, the thickness, number, arrangement, and materials of the members constituting the structural frame 20 are designed so that the rigidity of the first structural frame 21 is higher than that of the second structural frame 22. Because the first structural frame 21 has higher rigidity than the second structural frame 22, it is less prone to deflection than the second structural frame 22. In one example, the roof structure 12, which is the first structural frame 21, has a truss structure 14, which improves its rigidity compared to a case without a truss structure 14.

[0035] At least one of the first structural frame 21 and the second structural frame 22 has an extension 23 that extends toward the other. In this embodiment, the first structural frame 21 has the extension 23. The extension 23 extends from the first structural frame 21 toward the second structural frame 22. The extension 23 is connected, for example, to a roof beam 12C of the roof truss 12. The extension 23 extends, for example, from the roof beam 12C toward a floor beam 15A of the floor truss 15.

[0036] The second structural frame 22 is connected to the first structural frame 21. The second structural frame 22 is indirectly connected to the first structural frame 21, for example, via an extension 23 and a vibration suppression member 30. The extension 23 is configured, for example, as a support column connecting the first structural frame 21 and the second structural frame 22 in the vertical direction. The extension 23 is made of wood. The extension 23 may be made of a material such as metal or resin. The extension 23 may be positioned so as to be exposed on the second floor of the building body 11, or it may be positioned inside the wall that partitions the second floor of the building body 11.

[0037] The building structure 11 comprises a first structural frame 21, a second structural frame 22, and a vibration-damping member 30. The first structural frame 21 and the second structural frame 22 are connected via an extension 23 and a vibration-damping member 30. The vibration-damping member 30 connects the extension 23 and the second structural frame 22.

[0038] Although Figure 1 illustrates three roof beams 12C, there may be two or four or more roof beams 12C. Similarly, although Figure 1 illustrates three floor beams 15A, there may be two or four or more floor beams 15A. In addition, although Figure 1 illustrates one extension 23, there may be two or more extensions 23.

[0039] As shown in Figure 3, a groove 23G is provided in the extension 23. The groove 23G is provided on the surface of the extension 23 of the first frame 21 that faces the second frame 22. A vibration suppression member 30 is placed in the groove 23G.

[0040] <Vibration suppression member> As shown in Figures 2 and 3, the vibration suppression member 30 is configured to suppress vibrations of the second structural frame 22 in a building 10 that includes a first structural frame 21 and a second structural frame 22. The vibration suppression member 30 comprises a damping member 31 and an engaging member 32. The damping member 31 absorbs vibrations of the second structural frame 22, thereby suppressing vibrations of the second structural frame 22 in the building 10.

[0041] <Engaging member> The engaging member 32 engages the first structural frame 21 and the second structural frame 22. The engaging member 32 is fixed to one of the first structural frame 21 and the second structural frame 22, and engages with the other of the first structural frame 21 and the second structural frame 22 so as to be movably relative to it. In this embodiment, the first structural frame 21 and the second structural frame 22 are engaged by the engaging member 32 being fixed to the second structural frame 22 and engaging with the first structural frame 21 so as to be movably relative to it. The engaging member 32 is fixed to the floor beam 15A of the floor framing 15. The engaging member 32 engages with the roof framing 12 so as to be movably relative to it via the extension portion 23.

[0042] The engaging member 32 has a fixing portion 33 fixed to one of the first frame 21 and the second frame 22, and an engaging portion 34 that engages with the other of the first frame 21 and the second frame 22 so as to be movable relative to it. The frame 20 of the first frame 21 and the second frame 22 that the engaging portion 34 engages with is defined as the engaged frame 20A. In this embodiment, the engaged frame 20A is the first frame 21.

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

[0044] The fixing portion 33 is provided with a fixing hole 33H. A fixing pin member 35, which is fixed to the second structural body 22, is inserted through the fixing hole 33H. The fixing pin member 35 is fixed to the second structural body 22 by being inserted through a through hole provided in the second structural body 22. The fixing pin member 35 is, for example, a drift pin.

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

[0046] The engaging portion 34 is configured with an elongated hole 34H extending in the vertical direction. The elongated hole 34H is provided in the two support plates 34A. A pin member 36, which is fixed to the engaged structure 20A, is inserted through the elongated hole 34H. The pin member 36 is fixed to the first structure 21 by being inserted through a through hole provided in the first structure 21.

[0047] The fixing plate 34B is connected to the fixing portion 33, for example, by welding. The two support plates 34A are attached to the fixing plate 34B so as to extend upward from the fixing plate 34B. The engaging portion 34 may be formed by press-forming a single metal plate.

[0048] As shown in Figures 4 and 5, the fixing plate 34B is positioned at a distance D1 from the second structural frame 22 by fixing the fixing portion 33 to the second structural frame 22. The distance D1 is set according to the amount of movement of the second structural frame 22 relative to the first structural frame 21 when the second structural frame 22 vibrates.

[0049] Between the two support plates 34A, there is an arrangement section 37 in which the damping member 31 is positioned. The arrangement section 37 has a pressing surface 37A that presses the damping member 31 toward the bottom surface BS of the groove 23G in the vertical direction. The pressing surface 37A is the surface of the fixing plate 34B that faces the first structural frame 21. When the second structural frame 22 moves upward, the pressing surface 37A moves toward the bottom surface BS of the groove 23G as the fixing plate 34B moves upward together with the fixing part 33 fixed to the second structural frame 22.

[0050] <Damping member> As shown in Figure 3, the damping member 31 is positioned between the first structural body 21 and the second structural body 22. The damping member 31 may also be positioned between the first structural body 21 and the second structural body 22 so as not to receive a load from the first structural body 21 under normal conditions. Normal conditions refer to a state in which the second structural body 22 does not vibrate. The damping member 31 deforms in accordance with the relative movement between the first structural body 21 and the second structural body 22 in the vertical direction. Examples of damping members 31 include viscoelastic materials such as rubber, or elastic materials such as springs.

[0051] As shown in Figures 4 and 5, the damping member 31 of this embodiment is located in the groove 23G of the extension 23. The damping member 31 has an insertion hole 31H. In a front view, the insertion hole 31H overlaps with the elongated hole 34H of the engaging portion 34. A pin member 36 is inserted through the insertion hole 31H, which passes through the elongated hole 34H. By inserting the pin member 36 through the insertion hole 31H of the damping member 31, the damping member 31 is positioned in the groove 23G of the extension 23. The insertion hole 31H is, for example, a round hole. The insertion hole 31H may also be an elongated hole extending in the vertical direction.

[0052] The damping member 31 is positioned between the fixed portion 33 of the engaging member 32 and the engaged structure 20A. In this embodiment, the damping member 31 is positioned between the fixed portion 33 and the first structure 21. The damping member 31 is positioned in the groove portion 23G of the extension portion 23 by being positioned in the arrangement portion 37 of the engaging portion 34. 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 positioned, for example, along the engaging member 32. Specifically, the damping member 31 is positioned along the support plate 34A of the engaging portion 34 in the vertical direction.

[0053] <Operation of the Embodiment> The first operation of this embodiment will now be described. Since the engaging member 32 engages with the first structural frame 21 so as to be movable relative to it, and is fixed to the second structural frame 22, when the second structural frame 22 vibrates, the second structural frame 22 repeatedly moves relative to the first structural frame 21. Since the damping member 31 is positioned between the first structural frame 21 and the second structural frame 22, it deforms in accordance with the relative movement between the first structural frame 21 and the second structural frame 22. The damping member 31 absorbs the vibrations of the second structural frame 22. As a result, even if vibrations occur in the floor of the building 10, which is composed of the floor frame 15, which is the second structural frame 22, due to, for example, the walking of an occupant, the damping member 31 can absorb those vibrations.

[0054] The second operation of this embodiment will now be described. Since the first structural frame 21 is movable relative to the second structural frame 22, even if the first structural frame 21 deforms due to aging or other reasons, the deformation of the first structural frame 21 is less likely to be transmitted to the second structural frame 22. For this reason, in the building 10, even if the roof truss 12 included in the first structural frame 21 sags, that sag is less likely to be transmitted to the floor truss 15 included in the second structural frame 22. In this way, the load of the roof truss 12, which is the first structural frame 21, can be suppressed from being applied to the floor truss 15, which is the second structural frame 22.

[0055] The third function of this embodiment will now be described. The fixing portion 33 of the engaging member 32 can be constructed using a mortise pipe. The engaging portion 34 of the engaging member 32 can be constructed using one or more plates. Furthermore, the vibration suppression member 30 can be installed on the building structure 20 by a support column such as the extension portion 23. For this reason, the space required to install the vibration suppression member 30 is smaller compared to large-scale devices such as the conventional floor vibration control system known as TMD (Tuned Mass Damper).

[0056] A fourth function of this embodiment will now be described. In buildings, beams with large spans are sometimes used to create large floors. In addition, beams with large spans may be used on upper floors to accommodate open staircases. When beam spans are large, the floor beams are more susceptible to vibration due to foot traffic, which may cause discomfort to residents. The vibration damping member 30 allows for the easy installation of a floor vibration control system, thereby improving the design flexibility of the building 10.

[0057] A fifth function of this embodiment will now be described. By removing the pin member 36 and then sliding the damping member 31 out of the placement section 37, the damping member 31 can be removed from the groove section 23G without removing the engaging member 32 from the first structure 21 and the second structure 22. Therefore, for example, tuning of the damping member 31 can be easily performed after the construction of the building 10.

[0058] The sixth function of this embodiment will now be described. The rigidity of the first structural frame 21 is higher than that of the second structural frame 22. Therefore, the difference in the amount of deformation between the first structural frame 21 and the second structural frame 22 is absorbed by the deformation of the damping member 31 of the vibration suppression member 30. The higher the rigidity of the first structural frame 21 is compared to the rigidity of the second structural frame 22, the more effectively the vibration suppression member 30 can absorb vibrations.

[0059] <Effects of the Embodiment> The effects of this embodiment will now be explained. (1-1) The vibration suppression member 30 comprises a damping member 31 and an engaging member 32. The damping member 31 is positioned between the first structural body 21 and the second structural body 22. The engaging member 32 is fixed to one of the first structural body 21 and the second structural body 22 and engages with the other of the first structural body 21 and the second structural body 22 so as to be movably relative to it.

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

[0061] Because the first structural frame 21 and the second structural frame 22 are engaged by the engaging member 32, when the second structural frame 22 vibrates, displacement of the second structural frame 22 from the first structural frame 21 is suppressed. Therefore, vibrations of the second structural frame 22 can be effectively transmitted to the first structural frame 21.

[0062] (1-2) The engaging member 32 comprises a fixing portion 33 fixed to one of the first structural body 21 and the second structural body 22, and an engaging portion 34 that engages with the other of the first structural body 21 and the second structural body 22 so as to be movable relative to it. The damping member 31 is positioned between the fixing portion 33 and the structural body 20 of the first structural body 21 and the second structural body 22 that engages with the engaging portion 34.

[0063] With this configuration, the damping member 31 can be positioned so that it can be suitably deformed by vibrations of the second structural body 22.

[0064] (1-3) The engaging portion 34 is configured with an elongated hole 34H that extends in the vertical direction. A pin member 36, which is fixed to the engaged body 20A, is inserted through the elongated hole 34H.

[0065] With this configuration, the engaged body 20A can move relative to the engaging member 32 in the vertical direction along which the elongated hole 34H extends.

[0066] (1-4) The building body 11 comprises a first structural frame 21, a second structural frame 22, and a vibration suppression member 30. The first structural frame 21 is positioned differently from the second structural frame 22 in the vertical direction. The first structural frame 21 is constructed to have higher rigidity than the second structural frame 22. The first structural frame 21 and the second structural frame 22 are connected via an extension 23 and a vibration suppression member 30.

[0067] In this configuration, the second structural frame 22 is connected to the first structural frame 21 via the extension 23 and the vibration damping member 30. Since the rigidity of the first structural frame 21 is higher than that of the second structural frame 22, the vibration damping member 30 can effectively dampen the vibrations of the second structural frame 22.

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

[0069] With this configuration, the first structural frame 21 is configured as at least a part of the roof structure 12 having a truss structure 14, thus improving the rigidity of the first structural frame 21.

[0070] (1-6) The building body 11 comprises a first structural frame 21, a second structural frame 22, and a vibration suppression member 30. The first structural frame 21 is positioned differently from the second structural frame 22 in the vertical direction. The first structural frame 21 is constructed to have higher rigidity than the second structural frame 22. At least one of the first structural frame 21 and the second structural frame 22 has an extension 23 that extends toward the other. The first structural frame 21 and the second structural frame 22 are connected via the extension 23 and the vibration suppression member 30. The vibration suppression member 30 suppresses vibrations of the second structural frame 22.

[0071] In this configuration, the second structural frame 22 is connected to the first structural frame 21 via the extension 23 and the vibration damping member 30. Because the rigidity of the first structural frame 21 is higher than that of the second structural frame 22, the vibration damping member 30 can effectively dampen the vibrations of the second structural frame 22. By arranging the vibration damping member 30 between the first structural frame 21 and the second structural frame 22 in this way, a floor vibration control system can be constructed, making it easier to install a structure to suppress the vibrations of the second structural frame 22.

[0072] <Second Embodiment> Referring to Figure 6, the building 10 and vibration suppression member 30 according to the second embodiment will be described. In this embodiment, components that are substantially unchanged from those of the first embodiment are given the same reference numerals as those of the first embodiment, and their descriptions are omitted. In Figure 6, the left-right direction of the paper coincides with the up-down direction of the building 10.

[0073] The vibration suppression member 30 of this embodiment comprises a damping member 41, an intermediate body 42, a first engaging member 50, and a second engaging member 60. The first engaging member 50 and the second engaging member 60 correspond to the engaging member 32 of the first embodiment. The first engaging member 50 is fixed to the first frame 21 and engages the first frame 21 and the intermediate body 42 by engaging with the intermediate body 42 in a relative movable manner, except that it is configured similarly to the engaging member 32 of the first embodiment. The second engaging member 60 is fixed to the second frame 22 and engages the second frame 22 and the intermediate body 42 by engaging with the intermediate body 42 in a relative movable manner, except that it is configured similarly to the engaging member 32 of the first embodiment.

[0074] <Intermediate> The intermediate body 42 is positioned between the first structural body 21 and the second structural body 22.

The object of the first structural body 21 and the intermediate body 42 that the first engaging portion 52 engages with is defined as the first engaged structural body 24A. In this embodiment, the first engaged structural body 24A is the intermediate body 42. The first engaging portion 52 is positioned in the first groove portion 43G provided at the first end portion 43 of the intermediate body 42.

[0076] The first fixing part 51 is fixed, for example, to the extension part 23 of the first structural frame 21. The extension part 23 of the first structural frame 21 is provided with a hole 21H into which the first fixing part 51 is inserted, for example.

[0077] The first fixing portion 51 is provided with a first fixing hole. A first fixing pin member 53, which is fixed to the first structural frame 21, is inserted through the first fixing hole. The first fixing pin member 53 is fixed to the first structural frame 21 by being inserted through a through hole provided in the first structural frame 21. The first fixing pin member 53 is, for example, a drift pin.

[0078] The first engaging portion 52 is configured with a first elongated hole 52H that extends in the vertical direction. A first pin member 54, which is fixed to the first engaged body 24A, is inserted through the first elongated hole 52H. The first pin member 54 is fixed to the intermediate body 42 by being inserted through a through hole provided in the intermediate body 42.

[0079] <Second engaging member> The second engaging member 60 engages the second structural body 22 with the intermediate body 42. The second engaging member 60 has a second fixing portion 61 fixed to one of the second structural body 22 and the intermediate body 42, and a second engaging portion 62 that engages with the other of the second structural body 22 and the intermediate body 42 so as to be relatively movable. The object of the second structural body 22 and the intermediate body 42 that the second engaging portion 62 engages with is defined as the second engaged structural body 24B. In this embodiment, the second engaged structural body 24B is the intermediate body 42. The second engaging portion 62 is positioned in the second groove portion 44G provided at the second end portion 44 of the intermediate body 42.

[0080] The second fixing part 61 is fixed to the second structural frame 22. The second structural frame 22 is provided with a hole 22H into which, for example, the second fixing part 61 is inserted.

[0081] The second fixing portion 61 is provided with a second fixing hole. A second fixing pin member 63, which is fixed to the second structural frame 22, is inserted through the second fixing hole. The second fixing pin member 63 is fixed to the second structural frame 22 by being inserted through a through hole provided in the second structural frame 22. The second fixing pin member 63 is, for example, a drift pin.

[0082] The second engaging portion 62 is configured with a second elongated hole 62H that extends in the vertical direction. A second pin member 64, which is fixed to the second engaged body 24B, is inserted through the second elongated hole 62H. The second pin member 64 is fixed to the intermediate body 42 by being inserted through a through hole provided in the intermediate body 42.

[0083] <Damping member> The damping member 41 includes a first damping member 41A and a second damping member 41B. The first damping member 41A is configured similarly to the damping member 41 of the first embodiment, except that it is positioned between the first structural body 21 and the intermediate body 42. The second damping member 41B is configured similarly to the damping member 41 of the first embodiment, except that it is positioned between the second structural body 22 and the intermediate body 42. The first damping member 41A is positioned between the first fixing part 51 and the first engaged structural body 24A. The second damping member 41B is positioned between the second fixing part 61 and the second engaged structural body 24B.

[0084] <Operation of the Embodiment> The operation of this embodiment will now be explained. In this embodiment, since the damping member 41 has a first damping member 41A and a second damping member 41B, the volume of the damping member 41 is increased. Therefore, the vibration damping effect of the damping member 41 can be improved.

[0085] <Effects of the Embodiment> The effects of this embodiment will now be explained. (2-1) The vibration suppression member 30 comprises a damping member 41, an intermediate body 42, a first engaging member 50, and a second engaging member 60. The first engaging member 50 has a first fixing portion 51 fixed to one of the first frame 21 and the intermediate body 42, and a first engaging portion 52 that engages with the other of the first frame 21 and the intermediate body 42 so as to be relatively movable. The second engaging member 60 has a second fixing portion 61 fixed to one of the second frame 22 and the intermediate body 42, and a second engaging portion 62 that engages with the other of the second frame 22 and the intermediate body 42 so as to be relatively movable. The damping member 41 comprises a first damping member 41A and a second damping member 41B. The first damping member 41A is positioned between the first fixing portion 51 and the object of the first frame 21 and the intermediate body 42 that engages with the first engaging portion 52. The second damping member 41B is positioned between the second fixing portion 61 and the object among the second frame 22 and the intermediate body 42 that engages with the second engaging portion 62.

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

[0087] (2-2) The first engaging portion 52 is configured with a first elongated hole 52H that extends in the vertical direction. A first pin member 54, which is fixed to the first engaged body 24A, is inserted through the first elongated hole 52H. The second engaging portion 62 is configured with a second elongated hole 62H that extends in the vertical direction. A second pin member 64, which is fixed to the second engaged body 24B, is inserted through the second elongated hole 62H.

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

[0089] <Third Embodiment> Referring to Figures 7 to 9, the building 10 and vibration suppression member 30 according to the third embodiment will be described. In this embodiment, components that are substantially unchanged from those of the first embodiment are given the same reference numerals as those of the first embodiment, and their descriptions are omitted.

[0090] As shown in Figures 7 and 8, in this embodiment, the engaging member 32 is fixed to the first structural body 21 and engages with the second structural body 22 so as to be movably relative to it, thereby engaging the first structural body 21 and the second structural body 22. The engaging member 32 in this embodiment comprises a main body portion 70. An example of the main body portion 70 is a mortise pipe. The main body portion 70 is inserted into a hole 21H provided in the extension portion 23 of the first structural body 21 and into a hole 22H provided in the second structural body 22.

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

[0092] The engaging member 32 is configured with an elongated hole 73 that extends in the vertical direction. The elongated hole 73 is provided in the portion of the main body 70 that is inserted into a hole 22H provided in the second structural body 22. A pin member 74, which is interlocked with the structural body 20 that engages with the engaging member 32 so as to be movable relative to the first structural body 21 and the second structural body 22, is inserted through the elongated hole 73. The pin member 74 is fixed to the second structural body 22 by being inserted through a through hole provided in the second structural body 22.

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

[0094] As shown in Figure 9, the damping member 75 is positioned to surround at least a portion of the engaging member 32. In plan view, the damping member 75 surrounds at least a portion of the outer surface of the main body 70. In plan view, the damping member 75 has a recess 76. The engaging member 32 is located in the recess 76. An opening 76A is formed in the recess 76 of the damping member 75. The opening 76A is configured so that the damping member 75 can be removed from between the first structure 21 and the second structure 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 a 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 opening 76A deforms, allowing the main body 70 to pass through. The size of the opening 76A may be set to be larger than or equal to the diameter of the main body 70.

[0096] <Operation of the Embodiment> The first operation of this embodiment will now be described. Since the main body 70 of the engaging member 32 can be constructed using a mortise pipe, the vibration suppression member 30 of this embodiment is cost-effective to manufacture.

[0097] The second operation of this embodiment will now be described. The damping member 75 can be removed through the opening 76A while the first structural frame 21 and the second structural frame 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] <Effects of the Embodiment> The effects of this embodiment will now be explained. The engaging member 32 has an elongated hole 73 that extends in the vertical direction. A pin member 74 is inserted through the elongated hole 73 and is interlocked with the first structural body 21 and the second structural body 22, which engage with the engaging member 32 so as to be movable relative to it. The damping member 75 is arranged to surround at least a portion of the engaging member 32.

[0099] In this configuration, the frame 20, which engages with the engaging member 32 in a manner that allows it to move relative to the first frame 21 and the second frame 22, can move relative to the engaging member 32 in the vertical direction along which the elongated hole 73 extends.

[0100] <Fourth Embodiment> Referring to Figure 10, the building 10 and vibration suppression member 30 according to the fourth embodiment will be described. In this embodiment, components that are substantially unchanged from those of the first embodiment are given the same reference numerals as those of the first embodiment, and their descriptions are omitted.

[0101] As shown in Figure 10, the building body 11 of this embodiment comprises an outer frame 80 and an inner frame 90. The inner frame 90 is positioned within the outer frame 80. The outer frame 80 and the inner frame 90 constitute a framework that supports the building body 11.

[0102] The outer frame 80 includes a roof truss 81 and an outer support section 82. The outer support section 82 supports the roof truss 81. The outer support section 82 includes, for example, columns 83 that support the roof truss 81. The roof truss 81 is constructed, for example, in accordance with the roof truss 12 of the first embodiment. The roof truss 81 may have a truss structure 14.

[0103] The inner structure 90 includes a ceiling 91, a floor frame 92, and an inner support section 93. The inner support section 93 supports the ceiling 91 and the floor frame 92. The ceiling 91 is composed of, for example, ceiling beams 91A and ceiling panels positioned below the ceiling beams 91A. The floor frame 92 is constructed, for example, in accordance with the floor frame 15 of the first embodiment. The inner support section 93 includes, for example, columns 94 that support the ceiling 91 and the floor frame 92.

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

[0105] In this embodiment, the ceiling 91 is connected to the roof truss 81 via a connecting portion 100. Specifically, the connecting portion 100, which extends from the roof beam 81A of the roof truss 81, is connected to the ceiling beam 91A of the ceiling 91, thereby connecting the ceiling 91 to the roof truss 81.

[0106] The ceiling 91 includes the first structural frame 21. In this embodiment, the first structural frame 21 includes, for example, the ceiling beams 91A of the ceiling 91. The first structural frame 21 may also include the outer structural frame 80, the connecting parts 100, and the ceiling beams 91A. The first structural frame 21 may also include the roof truss 81, the connecting parts 100, and the ceiling beams 91A. In this embodiment, the first structural frame 21 is supported by the columns 94 and connecting parts 100 of the inner structural frame 90.

[0107] The floor frame 92 includes a second structural frame 22. In this embodiment, the second structural frame 22 includes, for example, floor beams 92A that constitute the floor frame 92. In this embodiment, the second structural frame 22 is supported by an inner structural frame 90.

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

[0109] <Effects of the Embodiment> The effects of this embodiment will now be explained. The building body 11 further comprises an outer frame 80 and an inner frame 90 positioned within the outer frame 80. The outer frame 80 has a roof truss 81 and an outer support section 82 that supports the roof truss 81. The inner frame 90 has a ceiling 91 including a first frame 21, a floor truss 92 including a second frame 22, and an inner support section 93 that supports the ceiling 91 and the floor truss 92. The ceiling 91 is connected to the roof truss 81 via a connection section 100.

[0110] With this configuration, since the roof truss 81 is supported by the outer support portion 82, vibrations from the floor located in the inner frame 90 are less likely to be transmitted to the roof truss 81 of the outer frame 80. By suppressing vibrations transmitted to the roof truss 81 from sources other than the connection portion 100, the vibration suppression member 30 can effectively attenuate vibrations transmitted from the connection portion 100 to the roof truss 81. As a result, the vibration suppression member 30 can effectively suppress vibrations of the second frame 22.

[0111] <Variation> The above embodiments are illustrative of possible forms of the building 10 and vibration-damping member 30, and are not intended to limit their forms. The building 10 and vibration-damping member 30 may take forms different from those illustrated in the above embodiments. Examples include forms in which some of the configurations of the embodiments are replaced, modified, or omitted, or forms in which new configurations are added to the embodiments. Modifications of the embodiments are shown below.

[0112] As shown in Figure 11, in the roof structure 12, multiple roof beams 12C may be arranged such that the pitch P1 between each roof beam 12C is 1m 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, thereby improving the rigidity of the roof structure 12. By improving the rigidity of the roof structure 12, which is the first structural body 21, vibrations of the second structural body 22 can be effectively suppressed.

[0113] As shown in Figure 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 may be set to 5 / 6 or less of the span S2 of the floor beam 15A. In the configuration shown in this modified example, the roof beam 12C may be positioned perpendicular to the floor beam 15A. By positioning the roof beam 12C in this way, the rigidity of the roof beam 12C, which is the first structural frame 21, can be made higher than the rigidity of the floor beam 15A, which is the second structural frame 22.

[0114] The location where the extension 23 and vibration-damping member 30 are positioned is not limited to the space between the roof truss 12 and the floor truss 15. For example, the first structural frame 21 may be configured as at least a part of the second-floor floor truss 15, and the second structural frame 22 may be configured as at least a part of the first-floor floor truss. For example, in a single-story building, the first structural frame 21 may be configured as at least a part of the roof truss, and the second structural frame 22 may be configured as at least a part of the first-floor floor truss.

[0115] The vibration suppression member 30 may be configured to suppress vibrations of the first structural body 21 in addition to, or instead of, vibrations of the second structural body 22.

[0116] The vibration-dampening member 30 may be placed anywhere between the first structural frame 21 and the second structural frame 22. In this modified example, in addition to the first structural frame 21, the second structural frame 22 may also have an extension 23 extending toward the first structural frame 21. The vibration-dampening member 30 may be placed between the extension 23 of the first structural frame 21 and the extension 23 of the second structural frame 22. Alternatively, the extension 23 of the first structural frame 21 may be omitted, and the vibration-dampening member 30 may be placed between the first structural frame 21 and the extension 23 of the second structural frame 22.

[0117] The damping members 31, 41, and 75 are not limited to viscoelastic materials such as rubber or elastic materials such as springs, but may also be mechanically constructed. Examples of mechanically constructed damping members 31 include hydraulic dampers, inertial mass dampers, magnetic dampers, and damping spools.

[0118] In the first embodiment, the engaging member 32 may be fixed to the first structural frame 21 and engaged with the second structural frame 22 so as to be movably relative to it. In this modified example, the second structural frame 22 may be provided with a groove in which the damping member 31 is positioned.

[0119] In the second embodiment, the first engaging member 50 may be engaged with the first structural body 21 so as to be movable relative to it and fixed to the intermediate body 42. Alternatively, the second engaging member 60 may be engaged with the second structural body 22 so as to be movable relative to it and 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 43 and the second end 44 of the intermediate body 42.

[0121] In the third embodiment, the engaging member 32 may be engaged with the first structural body 21 so as to be movable relative to it, and may also be fixed to the second structural body 22.

[0122] In the third embodiment, the damping member 75 may be divided into two parts. For example, in Figure 8, one damping member 75 may be positioned in front of the engaging member 32 in the plane of the drawing, and the other damping member 75 may be positioned behind the engaging member 32 in the plane of the drawing. In this modified example, in plan view, the entire outer surface of the main body 70 may be surrounded by the two damping members 75. Alternatively, the damping member 75 may be divided into three or more parts.
