Description

Technical Field

[0001] The present invention relates to an attachment structure of a vibration damping device.

Background Art

[0002] As an example of an attachment structure of a vibration damping device, the one described in Patent Document 1 is known. The vibration damping device described in this Patent Document 1 includes a rectangular frame in a rectangular frame shape, a pair of support portions provided facing left and right on the left and right vertical frames of the rectangular frame, and a vertically long pendulum member supported by the pair of support portions and capable of swinging about a substantially central portion of the pair of support portions, and a vibration damping member provided between an end portion of the pendulum member and the rectangular frame. The pendulum member is swingably supported with respect to the pair of support portions by slidably inserting two shafts provided on the pair of support portions into two holes formed in the pendulum member, and at least one of the two holes in the pendulum member is an elongated hole that is long in the lateral direction. The vibration damping device having the above-described configuration is incorporated in a portion of a building body surrounded by upper and lower structural members and left and right column members. Further, column feet connecting hardware is attached to the lower end portions of the left and right column members, and anchor bolts protruding from the foundation are connected to the column feet connecting hardware so that vibration of the ground is surely transmitted from the foundation. Then, vibration generated in the building body is transmitted to the pendulum member through deformation and displacement of the rectangular frame and the pair of support portions, so that the pendulum member swings, and the swing of the pendulum member is suppressed by the vibration damping member, thereby suppressing vibration generated in the building body.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In Patent Document 1, the column base hardware is embedded in the column material along the axial direction and connected to a column base bolt that protrudes downward from the lower end. As a result, the lower end of the column material becomes highly rigid with the column base bolt acting as a core, improving the connection strength of the column material to the lower structure such as the foundation or base. However, the increased rigidity at the lower end of the column becomes less susceptible to deformation when the building structure deforms due to vibrations such as earthquakes. In other words, the column ends up with both highly rigid and less rigid sections. When this happens, the highly rigid section of the column and its surrounding areas have difficulty following the deformation of the building structure and the vibration damping device, which can result in the vibration damping device being unable to perform its function effectively.

[0005] This invention was made in view of the above circumstances, and its objective is to facilitate the vibration damping function of a vibration damping device when deformation occurs in the building structure due to vibrations such as earthquakes. [Means for solving the problem]

[0006] The invention described in claim 1 is a vibration damping device 1 having the function of suppressing vibrations generated in the building structure, as shown in Figures 1 to 4, for example, The building frame consists of a lower frame 3 which is spaced apart below the vibration damping device 1, The building frame consists of an upper frame 30 which is spaced apart above the vibration damping device 1, The vibration damping device 1 is provided, and a vibration damping device assembly 5 is incorporated between the lower structure 3 and the upper structure 30. The vibration damping device assembly 5 is, Upper and lower structural members 26, 27 are provided between the vibration damping device 1 and the lower structure 3, and between the vibration damping device 1 and the upper structure 30, respectively. The vibration damping device 1 and the pair of left and right column members 25 provided on the left and right outer sides of the upper and lower structural members 26 and 27, The present invention is characterized by having a first fixing member 31 that extends from the pair of column members 25 toward the upper and lower structural members 26 and 27.

[0007] According to the invention described in claim 1, since the first fixing member 31 is provided from the pair of column members 25 toward the upper and lower structural members 26 and 27, the pair of column members 25 and the upper and lower structural members 26 and 27 can be integrated by this first fixing member 31. For example, if the building structure deforms due to vibrations such as an earthquake, the vibration damping device 1 suppresses the vibrations generated in the building structure. The first fixing member 31 integrates the pair of column members 25 and the upper and lower structural members 26 and 27, making it easier to make the pair of column members 25 and the upper and lower structural members 26 and 27 follow the operation of the vibration damping device 1 in response to the deformation of the building structure. As a result, the operation of the vibration damping device 1 and the operation of the pair of column members 25 and the upper and lower structural members 26 and 27 do not deviate from each other, making it easier to exert the vibration damping function of the vibration damping device 1.

[0008] The invention described in claim 2 is, for example, as shown in Figures 1 and 2, in the mounting structure of the vibration damping device 1 described in claim 1, The vibration damping device assembly 5 further includes left and right side members 28 and 29 provided on the left and right outer sides of the vibration damping device 1 and the upper and lower structural members 26 and 27, and on the left and right inner sides of the pair of column members 25. The first fixing member 31 is characterized in that it is provided from the pair of column members 25 toward the upper and lower structural members 26 and 27 via the left and right side members 28 and 29.

[0009] According to the invention described in claim 2, the left and right side members 28 and 29 are provided on the left and right outer sides of the vibration damping device 1 and the upper and lower structural members 26 and 27, and on the left and right inner sides of the pair of column members 25. Thus, they are provided as intermediate members sandwiched between the vibration damping device 1, the upper and lower structural members 26 and 27 and the pair of column members 25. When shear deformation occurs in the building frame due to vibrations such as earthquakes, the left and right side members 28 and 29 are less likely to be displaced in the direction away from the vibration damping device 1 and the upper and lower structural members 26 and 27 because the pair of column members 25 are located on the left and right outer sides. As a result, they play a role in connecting the vibration damping device 1 and the upper and lower structural members 26 and 27. Furthermore, since the first fixing member 31 is provided from the pair of column members 25 through the left and right side members 28 and 29 toward the upper and lower structural members 26 and 27, the first fixing member 31 firmly integrates the pair of column members 25, the left and right side members 28 and 29, and the upper and lower structural members 26 and 27, making it easier for the pair of column members 25, the left and right side members 28 and 29, and the upper and lower structural members 26 and 27 to follow the operation of the vibration damping device 1 in accordance with the deformation of the building frame. As a result, the operation of the vibration damping device 1 and the operation of the pair of column members 25, the left and right side members 28 and 29, and the upper and lower structural members 26 and 27 do not deviate from each other, making it easier to exert the vibration damping function of the vibration damping device 1.

[0010] The invention described in claim 3 is, for example, as shown in Figures 1 and 2, in the mounting structure of the vibration damping device 1 described in claim 2, The vibration damping device assembly 5 is further characterized by having a second fixing member 32 that extends from the pair of column members 25 toward the left and right side members 28 and 29.

[0011] According to the invention described in claim 3, the vibration damping device assembly 5 further includes a second fixing member 32 that extends from the pair of column members 25 toward the left and right side members 28 and 29, so that the pair of column members 25 and the left and right side members 28 and 29 can be integrated by this second fixing member 32. This makes it easier to make the pair of column members 25 and the left and right side members 28 and 29 follow the operation of the vibration damping device 1 in accordance with the deformation of the building frame. As a result, the operation of the vibration damping device 1 and the operation of the pair of column members 25 and the left and right side members 28 and 29 become less likely to diverge, so that the vibration damping function of the vibration damping device 1 can be more effectively utilized.

[0012] The invention described in claim 4 is, for example, as shown in Figures 1 to 4, in the mounting structure of the vibration damping device 1 described in claim 3, A column base connecting fitting 35 is attached to the lower end of the pair of column members 25 to connect the pair of column members 25 to the lower structure 3. The column base connecting hardware 35 is embedded in the pair of column members 25 along the axial direction and connected to column base bolts 40 that protrude downward from the lower ends of the pair of column members 25. Each of the first fixing member 31 and the second fixing member 32 is characterized in that multiple members are provided in a positional relationship that sandwiches the column base bolt 40.

[0013] According to the invention described in claim 4, a column base connecting fitting 35 for connecting the pair of column members 25 to the lower structure 3 is attached to the lower ends of the pair of column members 25, and the column base connecting fitting 35 is embedded in the pair of column members 25 along the axial direction and connected to a column base bolt 40 that protrudes downward from the lower ends of the pair of column members 25, so that the rigidity of the lower ends of the pair of column members 25 can be improved by the column base bolt 40 and the lower ends of the pair of column members 25 can be fixed securely and firmly to the lower structure 3. Furthermore, since a plurality of the first fixing members 31 and the second fixing members 32 are provided in a positional relationship sandwiching the column base bolts 40, it is possible to firmly integrate the pair of column members 25, the left and right side members 28 and 29, and the upper and lower structural members 26 and 27 while avoiding the column base bolts 40. In addition, the second fixing member 32 can firmly integrate the pair of column members 25 and the left and right side members 28 and 29.

[0014] The invention according to claim 5 is, for example, as shown in FIGS. 1 and 2, in the mounting structure of the vibration damping device 1 according to claim 4, The column base bolt 40 is characterized in that its upper end is set to a length such that it is located above the lower end of the vibration damping device 1.

[0015] According to the invention described in claim 5, since the upper end of the column base bolt 40 is set to a length such that it is located above the lower end of the vibration damping device 1, for example, the pull-out resistance can be improved as compared with the case where the length of the column base bolt 40 is set such that the upper end is located below the lower end of the vibration damping device 1. That is, by setting the column base bolt 40 to a length of a certain value or more, the pull-out resistance can be improved, for example, more effectively than when set to a length of a certain value or less, and thus it can effectively withstand the pull-out force generated in the pair of column members 25 due to the deformation of the building frame.

[0016] The invention according to claim 6 is, for example, as shown in FIGS. 1, 2, and 4, in the mounting structure of the vibration damping device 1 according to claim 4 or 5 In the mounting structure of the vibration damping device 1 described above, At the upper ends of the pair of column members 25, a column head connecting fitting 45 for connecting the pair of column members 25 and the upper frame 30 is attached. The column head connecting fitting 45 is embedded along the axial direction with respect to the pair of column members 25 and is connected to column head bolts 50 that protrude upward from the upper ends of the pair of column members 25. The column base bolt 40 is characterized in that it is formed to be longer than the column head bolt 50.

[0017] According to the invention described in claim 6, at the upper ends of the pair of column members 25, a column head connecting fitting 45 for connecting the pair of column members 25 and the upper housing 30 is attached. The column head connecting fitting 45 is embedded along the axial direction with respect to the pair of column members 25 and is connected to column head bolts 50 that project upward from the upper ends of the pair of column members 25. Therefore, the rigidity of the upper ends of the pair of column members 25 can be improved by the column head bolts 50, and the upper ends of the pair of column members 25 can be securely and firmly fixed to the upper housing 30. Furthermore, since the column base bolts 40 are formed to be longer than the column head bolts 50, the rigidity of the lower ends of the pair of column members 25 where stress is likely to concentrate can be surely improved by the long column base bolts 40. At the upper ends of the pair of column members 25 where stress is less likely to concentrate than at the lower ends, while exhibiting sufficient rigidity, the length of the column head bolts 50 can be minimized to reduce costs.

[0018] The invention described in claim 7, for example, as shown in FIG. 2, in the mounting structure of the vibration damping device 1 described in claim 6, At the upper end of the column member 25, a column hole 25b into which the lower end of the column head bolt 50 is inserted is formed, and an adhesive is filled in the gap between the column hole 25b and the column head bolt 50.

[0019] According to the invention described in claim 7, at the upper end of the column member 25, a column hole 25b into which the lower end of the column head bolt 50 is inserted is formed, and an adhesive is filled in the gap between the column hole 25b and the column head bolt 50. Therefore, the column member 25 and the column head bolt 50 can be integrated, contributing to an improvement in the bearing strength near the vibration damping device incorporated body 5.

[0020] The invention described in claim 8, for example, as shown in FIGS. 1 and 2, in the mounting structure of the vibration damping device 1 described in any one of claims 1 to 7, The vibration damping device incorporated body 5 is disposed so as to straddle at least the upper housing 30 and the upper structural member 26 among the upper and lower structural members 26 and 27, and further includes a gusset plate 33 for connecting them.

[0021] According to the invention described in claim 8, the vibration damping device assembly 5 is positioned across at least the upper frame 30 and the upper structural member 26 of the upper and lower structural members 26 and 27, and further includes a gusset plate 33 that connects them. This gusset plate 33 allows the upper end of the upper structural member 26 to be firmly connected to the upper frame 30. This makes it easier to make the upper and lower structural members 26 and 27 follow the operation of the vibration damping device 1 that occurs with the deformation of the building frame. [Effects of the Invention]

[0022] According to the present invention, when deformation occurs in the building structure due to vibrations such as earthquakes, it is possible to make it easier for the vibration damping function of the vibration damping device to be activated. [Brief explanation of the drawing]

[Figure 3] This is a cross-sectional view showing the state in which a column material is connected to an anchor bolt. [Figure 4] This is a perspective view showing a column base connecting fitting or a column top connecting fitting. [Modes for carrying out the invention]

[0024] Embodiments of the present invention will be described below with reference to the drawings. However, while the embodiments described below are subject to various technically preferred limitations for carrying out the present invention, the technical scope of the present invention is not limited to the following embodiments and illustrated examples. The directions in the following embodiments and illustrated examples are set solely for the convenience of explanation.

[0025] In Figures 1 and 2, reference numeral 1 denotes a vibration damping device. This vibration damping device 1 comprises a rectangular frame 7, a pair of support parts 8 provided opposite the rectangular frame 7, a vertically elongated pendulum member 15 positioned between the pair of support parts 8 and supported by the pair of support parts 8, and vibration damping boxes 16 provided at the upper and lower ends of the rectangular frame 7. Except for the vibration damping member 21 described later, the vibration damping device 1 is mostly made of metal such as iron or aluminum.

[0026] First, the rectangular frame 7 is formed by assembling a pair of left and right vertical frames 11 and a pair of top and bottom horizontal frames 12 into a rectangular frame shape, with the ends of the vertical frames 11 and the ends of the horizontal frames 12 being connected by pins. Therefore, the rectangular frame 7 can be deformed to form a parallelogram when force is applied in the left-right direction.

[0027] The vertical frame 11 is composed of a strip-shaped outer plate portion 11a that constitutes the outer surface of the rectangular frame 7, and a strip-shaped inner plate portion 11b that is formed perpendicular to the inner surface of the outer plate portion 11a and to which the support portion 8 is attached, and is formed in a T-shape in cross-section.

[0028] The horizontal frame 12 comprises a strip-shaped outer plate portion 12a that constitutes the outer circumferential surface of the rectangular frame 7, and inner plate portions 12b formed perpendicular to the inner surfaces of both ends of the outer plate portion 12a, and pin-connected to the ends of the inner plate portion 11b of the vertical frame 11. A vibration damping box 16 is attached to the inner plate portion 12b.

[0029] Next, the pair of support parts 8 are fixed to each of the inner plate parts 11b of the pair of left and right vertical frames 11, facing each other. Each support section 8 is composed of two rectangular support plates, and one side of each support plate is fixed to the inner plate section 11b of the vertical frame 11 by sandwiching the inner plate section 11b. A predetermined gap is provided between the two support plates, and the central part of the vertically elongated pendulum member 15 is inserted and supported between the two support plates.

[0030] Next, the pendulum member 15 is plate-shaped and formed in a vertically elongated octagonal shape, with its longitudinal direction oriented vertically. The left half of the central part of the pendulum member 15 is sandwiched between two support plates in one support part 8, and the right half is sandwiched between two support plates in the other support part 8. The pendulum member 15 is supported at its longitudinal center by the central end portions of a pair of support portions 8, 8. The pendulum member 15 is configured to swing around approximately the center between the pair of support portions 8, 8 when the rectangular frame 7 deforms due to vibrations such as earthquakes, causing the pair of support portions 8, 8 to be displaced.

[0031] Specifically, holes are formed opposite each other at the center of the tips of the two support plates in one support section 8, and holes are also formed opposite each other at the center of the tips of the two support plates in the other support section 8. Meanwhile, holes are formed in the center of the pendulum member 15, spaced apart to the left and right, and the left (or right) hole is an elongated hole that is longer horizontally.

[0032] Furthermore, the shaft 17 is inserted through the holes formed in the two support plates of one support portion 8 and through one of the elongated holes formed in the center of the pendulum member, so as to allow the pendulum member 15 to rotate and to slide in the longitudinal direction of the elongated hole. This shaft 17 is formed, for example, by a bolt 17 having a threaded portion at its tip, and this bolt 17 is inserted through the aforementioned holes and elongated hole, with nuts tightened onto the bolt 17 inserted through these holes and elongated hole.

[0033] Furthermore, a shaft 17 is inserted through the holes formed in the two support plates of the other support portion 8 and the other hole formed in the center of the pendulum member 15, so as to allow the pendulum member 15 to rotate. This shaft 17 is also formed from a bolt 17 having a threaded portion at its tip, and this bolt 17 is inserted through both of the aforementioned holes, with nuts tightened onto the bolt 17 inserted through these holes.

[0034] As a result, the pendulum member 15 is supported by a pair of support parts 8 via an axis 17, and the pendulum member 15 is configured to swing around approximately the center between the pair of support parts 8, 8, in other words, the center between the left and right axes 17, when the pair of support parts 8 are displaced due to vibrations such as earthquakes.

[0035] Next, the vibration damping box 16 comprises a box-shaped box 20 with openings on its top and bottom, a pair of vibration damping members 21 installed inside the box 20, and a plate 22 inserted between these vibration damping members 21 and fixed to the pair of vibration damping members 21. As the vibration damping member 21, for example, a viscoelastic body 21 formed from high-damping rubber is used.

[0036] Viscoelastic materials (vibration damping members) 21 are fixed to the opposing inner surfaces of the box 20 with adhesive or the like. The plate 22 is inserted between these viscoelastic materials 21, and the surface of the plate 22 is fixed to the pair of viscoelastic materials 21. One end of the plate 22 protrudes from the box 20 towards the pendulum member 15, and this protruding end is connected to the end of the pendulum member 15.

[0037] The vibration damping box 16 is attached to approximately the center of the horizontal frame 12 by installing the box 20 on the outer perimeter plate portion 12a of the horizontal frame 12, and then bolting the mounting plate formed on the box 20 to the inner plate portion 12b.

[0038] As shown in Figures 1 to 4, the vibration damping device 1, configured as described above, is incorporated into the building structure built on the foundation 4. The building structure comprises a lower structure 3 spaced apart below the vibration damping device 1, an upper structure 30 spaced apart above the vibration damping device 1, and a plurality of wall bodies 2 incorporated between the lower structure 3 and the upper structure 30. Furthermore, a base ring 4a is provided on the upper surface of the foundation 4. This base ring 4a is a ventilation base ring that connects the underfloor space and the outdoor space, allowing for ventilation of the underfloor space. The building structure is constructed on top of this base ring 4a.

[0039] The lower structural frame 3 is the floor structure of the building, and in this embodiment, floor panels are used. To explain in more detail, as shown in Figure 3, the floor panel 3 is constructed by assembling vertical and horizontal frame members 3a (equivalent to joists in conventional construction) in a rectangular shape, and then assembling multiple cross members (equivalent to joists) inside this rectangular frame to form a frame body, and then attaching a face material 3b (equivalent to a floorboard) to the top surface of this frame body. Furthermore, insulation material 3c made of glass wool, rock wool, etc. is installed between adjacent frame members 3a and cross members, and between adjacent cross members. Furthermore, the floor panel 3, together with the semi-foundation 3d which is set at the same height as the floor panel 3 and is provided along the outer perimeter of the building, constitutes the floor. Furthermore, the vibration damping device 1 may be positioned not only along the outer perimeter of the building structure, but also in the central part of the interior, not along the outer perimeter of the building structure. In such cases, as shown in the example in Figure 3, floor panels 3 will be installed in place of the half-sill plate 3d.

[0040] In this embodiment, the upper structure 30 is made of girders. However, it is not limited to this, and like the lower structure 3, it may also be a floor (i.e., the floor of the second floor). Furthermore, if the upper structure 30 is a floor structure, floor panels are used in the same way as the lower structure 3. The floor panels of the upper structure 30 are set at the same height as the floor panels and together with the half-floor gaps provided along the outer perimeter of the building, they constitute the floor. Furthermore, the upper structural frame 30 may also be a top-connecting member in a framed wall construction method. In that case, the upper ends of multiple wall bodies 2 and the upper ends of the vibration damping device assembly 5 (described later) are connected by the top-connecting member.

[0041] The wall body 2 is constructed by arranging a plurality of vertically positioned crossbars 2b at predetermined intervals on the left and right sides within a rectangular frame-shaped frame body 2a, fixing the upper and lower ends of the crossbars 2b to the frame body 2a, and further attaching surface materials 2c such as plywood to both the front and back surfaces of the frame body 2a. Multiple wall bodies 2 are installed on the lower structural frame 3, which consists of floor panels 3 and half-sills 3d, with gaps between them on the left and right. They may also be installed similarly on the upper structural frame 30.

[0042] Furthermore, a vibration damping device assembly 5, including a vibration damping device 1, is positioned between multiple adjacent wall bodies 2 that are spaced apart from each other on the left and right. As shown in Figures 1 and 2, the vibration damping device assembly 5 includes a pair of left and right column members 25, upper and lower structural members 26 and 27, left and right side members 28 and 29, a first fixing member 31, a second fixing member 32, and a gusset plate 33.

[0043] The pair of left and right column members 25 are rectangular wooden timbers, with the left and right side members 28 and 29 attached to their respective inner surfaces in the left-right direction. Furthermore, the inner surfaces of these column members 25 in the left-right direction are glued and fixed to the left and right outer surfaces of the left and right side members 28 and 29 in the left-right direction. Furthermore, metal end covers 25a, which are formed in a U-shape in cross-section, are attached to the upper and lower ends of the pair of column members 25. These pair of column members 25 are connected to the lower structure 3 and the upper structure 30 by column base connecting hardware 35 and column top connecting hardware 45, as will be described in detail later.

[0044] Of the upper and lower structural members 26 and 27, the upper structural member 26 is a rectangular structural member in front view that is installed between the vibration damping device 1 and the upper frame 30. Its upper end surface is flush with the upper end surfaces of the left and right side members 28 and 29, and is also flush with the upper end surface of the wall 2. Furthermore, the upper end surface of the upper structural member 26 is located above the upper end surface of the column member 25 and is in contact with the lower surface of the upper frame 30. Furthermore, the left-right length of the upper structural member 26 is equal to the left-right length of the vibration damping device 1, and the left-right outer surface of the upper structural member 26 is bonded and fixed to the left-right inner surface of the left and right side members 28 and 29 with adhesive. Furthermore, the lower end surface of the upper structural member 26 is fixed in contact with the horizontal frame 12 above the vibration damping device 1. This fixing is done by screwing fasteners such as screws or wood screws from the outer perimeter plate portion 12a of the horizontal frame 12 into the upper structural member 26, and by bonding the lower end surface of the upper structural member 26 to the outer perimeter plate portion 12a with adhesive. The upper structural member 26 is formed such that its length in the depth direction (thickness direction) is shorter than its length in the vertical and horizontal directions when viewed from the front. Therefore, this upper structural member 26 may be considered to be plate-shaped or thick plate-shaped. In addition, the depth dimension of the upper structural member 26 in this embodiment (for example, 90 mm, 120 mm, etc.) is approximately equal to the depth dimension of the left and right side members 28, 29, and is approximately equal to the depth dimension of the pair of column members 25. It may also be approximately equal to the depth dimension of the upper frame 30 and wall 2 in this embodiment. Depending on the upper frame 30, it may be shorter than the depth dimension of the upper frame 30. The upper structural member 26 is made of wood-based materials such as LVG (laminated veneer lumber), LVL (laminated veneer lumber), or plywood.

[0045] Of the upper and lower structural members 26 and 27, the lower structural member 27 is a rectangular structural member in front view that is installed between the vibration damping device 1 and the lower frame 3, and is made of the same wood material as the upper structural member 26. Its lower end surface is located below the lower end surface of the column member 25 and is in contact with the upper surface of the lower frame 3. Furthermore, the left-right length of the lower structural member 27 is equal to the left-right length of the vibration damping device 1 and the upper structural member 26, and the left-right outer surface of the lower structural member 27 is bonded and fixed to the left-right inner surface of the left and right side members 28 and 29 with adhesive. Furthermore, the upper end surface of the lower structural member 27 is fixed in contact with the horizontal frame 12 below the vibration damping device 1. This fixing is done by screwing fasteners such as screws or wood screws into the lower structural member 27 from the outer perimeter plate portion 12a of the horizontal frame 12, and by bonding the upper end surface of the lower structural member 27 to the outer perimeter plate portion 12a with adhesive. The lower structural member 27 is formed such that its length in the depth direction (thickness direction) is shorter than its length in the vertical direction and the length in the horizontal direction when viewed from the front. Its dimensional setting is the same as that of the upper structural member 26.

[0046] The left and right side members 28 and 29 are rectangular wooden prisms, and the left and right vertical frames 11 of the vibration damping device 1 are attached to their inner surfaces in the left-right direction at the center in the height direction. This attachment is performed by screwing fasteners such as screws or wood screws from the outer perimeter plate portion 11a of the vertical frame 11 to the column member 25, and by bonding the outer perimeter plate portion 11a to the side surface of the column member 25 with adhesive. Furthermore, the upper structural member 26 is adhesively fixed to the inner surfaces in the left-right direction at the upper ends in the height direction of the left and right side members 28 and 29. In addition, the lower structural member 27 is adhesively fixed to the inner surfaces in the left-right direction at the lower ends in the height direction of the left and right side members 28 and 29. In other words, the left and right side members 28 and 29 play a role in connecting the vibration damping device 1 with the upper and lower structural members 26 and 27 when shear deformation occurs in the building frame due to vibrations such as earthquakes. To put it another way, the vibration damping device 1 and the upper and lower structural members 26 and 27 are integrated by the left and right side members 28 and 29. Furthermore, the upper and lower structural members 26 and 27 and the left and right side members 28 and 29 form a rectangular frame, and the vibration damping device 1 is installed inside this frame.

[0047] The first fixing member 31 is a fixing member that is provided from a pair of column members 25 toward the upper and lower structural members 26 and 27 via the left and right side members 28 and 29, and a long screw is used, for example. That is, the first fixing member 31 is screwed into the pair of column members 25 from the left and right outer surfaces, and its tip reaches the upper and lower structural members 26 and 27. The first fixing members 31 located on the upper structural member 26 side are provided at two height positions, one above and one below, and also at two locations in the front-back direction at the same height position. In other words, there are four first fixing members 31 on the left side and four on the right side, located on the upper structural member 26 side. Furthermore, the first fixing members 31 located on the lower structural member 27 are provided at two height positions, one above and one below, and also at two locations in the front-back direction at the same height position. In other words, there are four first fixing members 31 on the left side and four on the right side, located on the lower structural member 27 side.

[0048] The second fixing member 32 is a fixing member provided from the pair of column members 25 toward the left and right side members 28 and 29, and a long screw is used, for example. That is, the second fixing member 32 is screwed in from the left and right outer surfaces of the pair of column members 25, and its tip reaches the left and right side members 28 and 29, but does not reach the vibration damping device 1. Therefore, the length of the second fixing member 32 is set to be shorter than that of the first fixing member 31. Furthermore, the second fixing members 32 are positioned within the area where the vibration damping device 1 is located (the vertical center of the vibration damping device assembly 5), and are provided at four height positions vertically within that area, as well as at two positions in the front-back direction at the same height. In other words, there are eight second fixing members 32 on the left side and eight on the right side.

[0049] The gusset plates 33 are rectangular plates made of metal such as iron plates, and in this embodiment, as shown in Figures 1 and 2, three gusset plates 33 are used. Of these gusset plates 33, the one in the middle is positioned across the upper frame 30 and the upper structural member 26. The gusset plates 33 on the left and right are positioned across the upper frame 30, the upper structural member 26, and the left and right side members 28 and 29. They are fixed in place by fasteners such as nails. Furthermore, the gusset plates 33 are installed in the same arrangement on the back side as well as the front side of the building structure shown in Figures 1 and 2, and are fixed in place with fasteners such as nails. As a result, the upper end of the vibration damping device assembly 5 and the lower end of the upper structure 30 are connected.

[0050] Next, we will describe a structure in which a pair of column members 25 are connected to the lower structural frame 3 and the upper structural frame 30. In other words, a column base connecting fitting 35 is attached to the lower end of each pair of column members 25 to connect the pair of column members 25 to the lower structure 3, and an anchor bolt (anchor) 36 extending from the foundation 4 and penetrating the lower structure 3 is connected to this column base connecting fitting 35. Furthermore, a column head connecting fitting 45 is attached to the upper end of each pair of column members 25 to connect the pair of column members 25 to the upper structure 30, and an anchor bolt (anchor) 46 that extends through the upper structure 30 is connected to this column head connecting fitting 45.

[0051] As shown in Figures 3 and 4, the column base connecting hardware 35 comprises a hardware body 35a, an anchor insertion hole 35b, a through hole 35c, and an opening 35d. The metal fitting body 35a is made of iron and is box-shaped, with openings 35d formed on the front and back sides. These openings 35d are formed on the entire sides of the front and back of the metal fitting body 35a, allowing tools such as spanners, wrenches, and screwdrivers to be inserted into the metal fitting body 35a. The anchor insertion hole 35b is a circular hole formed in the center of the bottom plate of the metal fitting body 35a. The through hole 35c is a circular hole formed in the center of the top plate of the metal fitting body 35a, and is formed to be approximately the same diameter as the anchor insertion hole 35b and is arranged coaxially.

[0052] As shown in Figures 2 and 3, the lower structure 3 is installed on the upper surface of the foundation 4. Anchor bolts (anchors) 36 are embedded inside the foundation 4, and the upper ends of these anchor bolts 36 penetrate the lower structure 3 (floor panel 3 and half-sill plate 3d) and protrude from the upper surface of the lower structure 3. The upper end of the anchor bolt 36 is screwed onto a nut 37 (round nut) and then inserted into the anchor insertion hole 35b of the column base connecting hardware 35. A nut 38 is screwed onto the upper end of the anchor bolt 36 and tightened. As a result, the column base connecting hardware 35 is fixed to the upper end of the anchor bolt 36 with the bottom plate of the hardware body 35a sandwiched between the nuts 37 and 38. In this state, a predetermined gap S is provided between the column base connecting hardware 35 and the lower structure 3. The tightening of the nut 38 is performed by inserting a tool such as a spanner or wrench through the opening 35d of the column base connecting hardware 35.

[0053] Furthermore, the lower end of the column member 25 is connected to the upper surface of the column base connecting hardware 35. The upper surface of the column base connecting hardware 35 and the end cover 25a provided on the lower end of the column member 25 are in contact. A column base bolt 40, which protrudes downward from the lower end of the column member 25, is embedded in the column member 25 along its axial direction. In other words, a column hole 25b extending upward from the lower end surface is formed along the axis of the column member 25 at the lower end of the column member 25, and the column base bolt 40 is embedded in this column hole 25b. Although not shown in the diagram, a gap is formed between the column base bolt 40 and the inner wall of the column hole 25b. This gap is filled with adhesive. For example, epoxy adhesive or urethane adhesive can be used as this adhesive. The lower end of a column base bolt 40 is inserted through the through hole 35c of the column base connecting hardware 35, and a nut 42 is screwed onto the lower end of the column base bolt 40 and tightened. The nut 42 is tightened by inserting a tool such as a spanner or wrench through the opening 35d of the column base connecting hardware 35.

[0054] Next, the column head connecting hardware 45, as shown in Figures 1, 2, and 4, comprises a hardware body 45a, an anchor insertion hole 45b, a through hole 45c, and an opening 45d. Its configuration is substantially the same as that of the column base connecting hardware 35, so a detailed explanation is omitted. In the case of the column head connecting hardware 45, the anchor insertion hole 45b is located at the top, and the through hole 45c is located at the bottom.

[0055] As shown in Figures 1 and 2, anchor bolts (anchors) 46 are provided through the upper structure 30, and the lower end of the anchor bolt 46 protrudes from the lower surface of the upper structure 30. The upper end of the anchor bolt 46 protrudes from the upper surface of the upper structure 30 and a nut is screwed onto it, but a counterbore may be formed on the upper surface of the upper structure 30, and the upper end of the anchor bolt 46 and the nut may be housed within the counterbore. The lower end of the anchor bolt 46 is inserted into the anchor insertion hole 45b of the column head connecting hardware 45, and a nut 48 is screwed onto the lower end of the anchor bolt 46 and tightened. The nut 48 is tightened by inserting a tool such as a spanner or wrench through the opening 45d of the column head connecting hardware 45.

[0056] Furthermore, the lower end of the column member 25 is connected to the lower surface of the column head connecting fitting 45. The lower surface of the column head connecting fitting 45 and the end cover 25a provided on the upper end of the column member 25 are in contact. A column head bolt 50, which protrudes upward from the upper end of the column member 25, is embedded in the column member 25 along its axial direction. In other words, a column hole 25b extending downward from the upper end surface is formed along the axis of the column member 25 at the upper end of the column member 25, and the column head bolt 50 is embedded in this column hole 25b. Also, similar to the column base bolt 40, adhesive is filled into the gap between the column head bolt 50 and the inner wall of the column hole 25b. The upper end of a column head bolt 50 is inserted through the through hole 45c of the column head connecting fitting 45, and a nut 52 is screwed onto the upper end of the column head bolt 50 and tightened. The nut 52 is tightened by inserting a tool such as a spanner or wrench through the opening 45d of the column head connecting fitting 45.

[0057] In this embodiment, the column base bolts 40 and column head bolts 50 are embedded in the column holes 25b of the pair of column members 25 as described above, and filled with adhesive, thereby integrating them with the pair of column members 25. This method is known as a glue-in rod, and by connecting the column base bolts 40 and column head bolts 50 embedded in the pair of column members 25 in this manner to the building frame (lower frame 3, upper frame 30) via the column base connecting hardware 35 and column head connecting hardware 45, it is possible to improve the load-bearing capacity near the vibration damping device assembly 5. Furthermore, in this embodiment, the glue-in rod method is employed, and the upper end of the vibration damping device assembly 5 and the lower end of the upper frame 30 are connected by a gusset plate 33, but these do not necessarily have to be used in combination. That is, if the gusset plate 33 is used as described above, the column head bolts 50 do not need to be embedded in the pair of column members 25 using the glue-in rod method, and if the glue-in rod method is used, the gusset plate 33 does not need to be used.

[0058] Furthermore, as described above, the first fixing member 31 and the second fixing member 32 are provided at two locations in the front-back direction at the same height position, which means that multiple fixing members are provided in a positional relationship that sandwiches the column base bolt 40 and the column top bolt 50 (on both sides of the column base bolt 40 and the column top bolt 50 when viewing the left-right outer surface of the pair of column members 25). In other words, on the left and right outer surfaces of a pair of column members 25, a first fixing member 31 and a second fixing member 32 are provided at two locations on the front and back sides, respectively, and the axis of the column member 25 passes through the midpoint between the first fixing member 31 on the front and back sides, and the midpoint between the second fixing member 32 on the front and back sides. At the lower end of the column member 25, a column base bolt 40 is embedded along its axis, and at the upper end, a column head bolt 50 is embedded along its axis. Furthermore, on the left and right outer surfaces of the pair of column members 25, screw holes 25c are formed at two locations each on the front and back sides at the height positions where the first fixing member 31 and the second fixing member 32 are installed, for passing the first fixing member 31 and the second fixing member 32 through. The screw holes 25c may be formed only on the pair of column members 25, or they may be formed on the left and right side members 28, 29. They may also be formed on the upper and lower structural members 26, 27.

[0059] Furthermore, the upper end of the column base bolt 40 is located above the lower end of the vibration damping device 1. More specifically, the upper end of the column base bolt 40 is located at a height close to the lower ends of the pair of support parts 8. As a result, the iron core is embedded to a considerable height at the lower end of the column member 25, resulting in high rigidity. Furthermore, the column base bolts 40 are formed to be longer than the column head bolts 50. This is to take into account the difference in stress caused by vibrations such as earthquakes, and since stress tends to concentrate at the lower end of the column member 25, the column base bolts 40 are formed to be longer. Furthermore, in this embodiment, as a result of setting the column base bolt 40 to the required length for design, the upper end of the column base bolt 40 is located above the lower end of the vibration damping device 1. This is preferable because it improves the pull-out resistance. On the other hand, as a result of setting the column base bolt 40 to the required length for design, the upper end of the column base bolt 40 may be located below the lower end of the vibration damping device 1. Therefore, in this embodiment, as described above, the upper end of the column base bolt 40 is located above the lower end of the vibration damping device 1, but this is not limited to this, and it can be modified as appropriate without departing from the spirit of the present invention. Furthermore, the column base bolts 40 are assumed to have a diameter that meets the required dimensions in the design. In other words, if the diameter of the column base bolts 40 is appropriate, it is preferable because it can improve the pull-out resistance.

[0060] In a building structure to which the vibration damping device 1 is attached, deformation occurs due to lateral vibrations such as earthquakes, causing the lower structure 3 and the upper structure 30 to displace in opposite directions horizontally (left-right). As a result, the upper and lower horizontal frames 12 of the rectangular frame 7 of the vibration damping device 1 are displaced so as to shift from side to side, and the vertical frame 11 tilts laterally, causing the rectangular frame 7 to deform into a roughly parallelogram shape. When the rectangular frame 7 deforms into a roughly parallelogram shape, the pair of support parts 8 are displaced so as to move diagonally upward and downward, separating from each other. At this time, the vibration damping device assembly 5 also deforms into a roughly parallelogram shape, similar to the rectangular frame 7 in the vibration damping device 1. However, if the integration of the upper and lower structural members 26, 27, the left and right side members 28, 29 located outward in the left and right directions, and the pair of column members 25 located further outward in the left and right directions is insufficient, the vibration damping device 1 will have difficulty performing its vibration damping function. In this embodiment, the first fixing member 31 allows for sufficient integration of the pair of column members 25, the left and right side members 28, 29, and the upper and lower structural members 26, 27, and the second fixing member 32 allows for integration of the pair of column members 25 and the left and right side members 28, 29.

[0061] When the pair of support parts 8 are displaced, the pendulum member 15 swings like a pendulum around approximately the center between the pair of support parts 8, and the swing is amplified at the ends of the pendulum member 15, thereby amplifying the displacement of the pair of support parts 8. Furthermore, the end of the pendulum member 15 is connected to the plate 22 of the vibration damping box 16. This plate 22 is inserted between a pair of viscoelastic bodies 21 and fixed to the pair of viscoelastic bodies 21, so that the deformation of these viscoelastic bodies 21 can be amplified. Therefore, the vibration damping function can be effectively activated even with small deformations of the building.

[0062] Furthermore, since the deformation rate of the viscoelastic body 21 can be amplified compared to the deformation rate of the building structure, when a viscoelastic body made from a viscoelastic material whose energy absorption performance is proportional to the deformation rate is used, energy can be absorbed more efficiently and a larger damping force can be exerted.

[0063] This embodiment provides the following excellent effects. Since the first fixing member 31 is provided extending from the pair of column members 25 toward the upper and lower structural members 26 and 27, the pair of column members 25 and the upper and lower structural members 26 and 27 can be integrated by this first fixing member 31. For example, if the building structure deforms due to vibrations such as an earthquake, the vibration damping device 1 suppresses the vibrations generated in the building structure. The first fixing member 31 integrates the pair of column members 25 and the upper and lower structural members 26 and 27, making it easier to make the pair of column members 25 and the upper and lower structural members 26 and 27 follow the operation of the vibration damping device 1 in response to the deformation of the building structure. As a result, the operation of the vibration damping device 1 and the operation of the pair of column members 25 and the upper and lower structural members 26 and 27 do not deviate from each other, making it easier to exert the vibration damping function of the vibration damping device 1.

[0064] Furthermore, the left and right side members 28 and 29 are located on the left and right outer sides of the vibration damping device 1 and the upper and lower structural members 26 and 27, and on the left and right inner sides of the pair of column members 25. Therefore, they are provided as intermediate members sandwiched between the vibration damping device 1, the upper and lower structural members 26 and 27, and the pair of column members 25. When shear deformation occurs in the building frame due to vibrations such as earthquakes, the left and right side members 28 and 29 are less likely to be displaced in the direction away from the vibration damping device 1 and the upper and lower structural members 26 and 27 because the pair of column members 25 are located on the left and right outer sides. As a result, they play a role in connecting the vibration damping device 1 and the upper and lower structural members 26 and 27. Furthermore, since the first fixing member 31 is provided from the pair of column members 25 through the left and right side members 28 and 29 toward the upper and lower structural members 26 and 27, the first fixing member 31 firmly integrates the pair of column members 25, the left and right side members 28 and 29, and the upper and lower structural members 26 and 27, making it easier for the pair of column members 25, the left and right side members 28 and 29, and the upper and lower structural members 26 and 27 to follow the operation of the vibration damping device 1 in accordance with the deformation of the building frame. As a result, the operation of the vibration damping device 1 and the operation of the pair of column members 25, the left and right side members 28 and 29, and the upper and lower structural members 26 and 27 do not deviate from each other, making it easier to exert the vibration damping function of the vibration damping device 1.

[0065] Furthermore, the vibration damping device assembly 5 also has a second fixing member 32 that extends from the pair of column members 25 toward the left and right side members 28 and 29, so that the pair of column members 25 and the left and right side members 28 and 29 can be integrated by this second fixing member 32. This makes it easier to make the pair of column members 25 and the left and right side members 28 and 29 follow the operation of the vibration damping device 1 in accordance with the deformation of the building frame. As a result, the operation of the vibration damping device 1 and the operation of the pair of column members 25 and the left and right side members 28 and 29 become less likely to diverge, so that the vibration damping function of the vibration damping device 1 can be more effectively utilized.

[0066] Furthermore, a column base connecting fitting 35 is attached to the lower end of the pair of column members 25 to connect the pair of column members 25 to the lower structure 3. The column base connecting fitting 35 is embedded in the pair of column members 25 along the axial direction and connected to a column base bolt 40 that protrudes downward from the lower end of the pair of column members 25. As a result, the rigidity of the lower end of the pair of column members 25 can be improved by the column base bolt 40, and the lower end of the pair of column members 25 can be securely and firmly fixed to the lower structure 3. Furthermore, since multiple first fixing members 31 and second fixing members 32 are provided in positions that sandwich the column base bolts 40, the pair of column members 25, the left and right side members 28, 29 and the upper and lower structural members 26, 27 can be firmly integrated while avoiding the column base bolts 40, and the pair of column members 25 and the left and right side members 28, 29 can be firmly integrated by the second fixing member 32.

[0067] Furthermore, since the column base bolt 40 is set to a length such that its upper end is positioned above the lower end of the vibration damping device 1, the pull-out resistance can be improved compared to, for example, the case where the length of the column base bolt 40 is set such that its upper end is positioned below the lower end of the vibration damping device 1. In other words, by setting the column base bolt 40 to a length above a certain level, the pull-out resistance can be improved compared to, for example, the case where it is set to a length below a certain level, so it can effectively withstand the pull-out force generated in the pair of column members 25 due to the deformation of the building structure.

[0068] Furthermore, a column head connecting fitting 45 is attached to the upper end of each pair of column members 25 to connect the pair of column members 25 to the upper structure 30. The column head connecting fitting 45 is embedded in the pair of column members 25 along the axial direction and connected to a column head bolt 50 that protrudes upward from the upper end of each column member 25. This allows the column head bolt 50 to improve the rigidity of the upper end of each column member 25 and to securely and firmly fix the upper end of each column member 25 to the upper structure 30. Furthermore, since the column base bolts 40 are formed to be longer than the column head bolts 50, the longer column base bolts 40 can reliably improve the rigidity of the lower ends of the pair of column members 25 where stress tends to concentrate, while at the upper ends of the pair of column members 25, where stress is less likely to concentrate than at the lower ends, sufficient rigidity can be achieved, and costs can be reduced by minimizing the length of the column head bolts 50.

[0069] Furthermore, a column hole 25b is formed at the upper end of the column member 25 into which the lower end of the column head bolt 50 is inserted, and adhesive is filled in the gap between the column hole 25b and the column head bolt 50. This allows the column member 25 and the column head bolt 50 to be integrated, contributing to improved load-bearing capacity near the vibration damping device assembly 5.

[0070] Furthermore, the vibration damping device assembly 5 is positioned to span at least the upper frame 30 and the upper structural member 26 of the upper and lower structural members 26 and 27, and further includes a gusset plate 33 that connects them. This gusset plate 33 allows the upper end of the upper structural member 26 to be firmly connected to the upper frame 30. This makes it easier for the upper and lower structural members 26 and 27 to follow the operation of the vibration damping device 1 that occurs with the deformation of the building frame.

[0071] [Variation] In the above embodiment, the vibration damping device assembly 5 had left and right side members 28 and 29 provided on the left and right outer sides of the vibration damping device 1 and the upper and lower structural members 26 and 27, and on the left and right inner sides of the pair of column members 25. In contrast, in this modified example, although not shown in the figures, the vibration damping device assembly 5 does not have left and right side members 28 and 29. In other words, in this modified example, a pair of column members 25 are provided on the left-right outer sides of the vibration damping device 1 and the upper and lower structural members 26 and 27. The first fixing member 31 is provided from the pair of column members 25 toward the upper and lower structural members 26 and 27. Furthermore, the gusset plate 33 is positioned to span only the upper frame 30 and the upper structural member 26, connecting them together.

[0072] Furthermore, in the above embodiment, the vibration damping device 1 is configured to include a rectangular frame 7, a pair of support parts 8, a pendulum member 15, and a vibration damping box 16, but it is not limited to this configuration and can be modified as appropriate without departing from the spirit of the present invention. In other words, any configuration that can be provided for a vibration damping device assembly 5 incorporated between the lower structure 3 and the upper structure 30 is applicable.

[0073] Furthermore, the structure of the building frame into which the vibration damping device assembly 5 is incorporated only needs to have a lower frame below the vibration damping device assembly 5 and an upper frame above the vibration damping device assembly 5. Therefore, it can be applied to, for example, conventional timber frame structures, panel construction structures, two-by-four construction structures, or building frames including steel frames.
