  2. Description of the Related Art Conventionally, there is known a vibration control structure that reduces building shaking caused by an earthquake or the like to improve building damage or occupant safety (see Patent Document 1).

In the vibration damping structure of Patent Document 1, a rubber viscoelastic damper is interposed between a frame structure composed of a plurality of beams and columns and a wall panel, and both shear directions (in the plane of the wall panel) The vibration energy due to the earthquake is absorbed by inputting the deviation in the direction) into the viscoelastic damper.
JP 2005-282231 A

  However, in the above-described conventional vibration damping structure, the viscoelastic damper may not work effectively when the wall panel moves in the out-of-plane direction (the crossing direction of the wall surface). That is, because the positions of the deformation axes of the wall panel and the viscoelastic damper are shifted, deformation in the out-of-plane direction of the wall panel also occurs, and the deformation in the shear direction may not be sufficiently input to the viscoelastic damper.

  And if the deformation | transformation of the direction where the function of a viscoelastic damper is exhibited is not input, a viscoelastic damper cannot be functioned efficiently and there exists a possibility that a damping effect may reduce.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a building damping structure capable of inputting deformation in a direction in which the damping member functions efficiently, and a damping member used therefor.

  To achieve the above object, the vibration control structure of a building according to the present invention is a vibration control structure of a building constructed by attaching a wall panel to a frame structure formed by combining a plurality of columns and beams. The damping member that connects at least one of the pillars, the beams, or the intermediate pillars whose ends are connected to the beams, and at least one of the wall panels as a mounting material is a belt-like member having a curved surface. In addition, the mounting is carried out through fixing portions respectively provided at both ends of the curved surface directed in a curved direction when viewed on a surface substantially orthogonal to both the wall surface of the wall panel and the mounting surface of the mounting material. It is attached to a material and the said wall panel, respectively.

  Here, the frame structure is provided with a plurality of studs whose ends are coupled to the beams, and both side edges of the wall panel are pin-supported by the studs or the pillars, and the beams are attached to a mounting material. The wall panel and the beam can be connected by the damping member.

  Further, the mounting surface of the mounting material may be a flange surface substantially orthogonal to the wall panel. Furthermore, the wall panel is provided with a projecting piece that is substantially parallel to the mounting surface of the mounting material, and one of the fixed portions of the damping member is fixed to the projecting piece, and the other fixed portion Can be fixed to the mounting surface.

  Further, the vibration damping member is formed in a substantially semicircular shape in cross section, and one end of the semicircle serves as one of the fixed portions, the other end serves as the other fixed portion, and the curved surface is disposed on the wall panel side. You may comprise.

  Further, the vibration damping member may be formed in a substantially circular shape in cross-section, and one of the fixed portions and the other fixed portion may be formed at opposite positions of the circle.

  In addition, the vibration damping member is formed with a continuous curved surface whose direction is opposite to each other, and the fixing portion is provided at one end portion thereof and fixed to the wall panel, and the fixing portion provided at the other end portion. A part can also be set as the structure fixed to the said attachment surface.

  In addition, the vibration damping member of the present invention is a belt-like member having a curved surface, is formed in a substantially circular shape in cross section, and has a pair of fixing portions formed at positions opposed to the circle.

  Further, it may be a belt-like member having a curved surface, and a curved surface having a diametrically opposite direction may be continuously formed, and fixed portions may be provided at both ends thereof.

  The vibration damping structure of the building of the present invention configured as described above includes a fixed portion for attaching to a vibration damping member that connects a wall panel with a mounting material such as a column, a beam, or a stud, and between the fixed portions. And a curved surface formed. In addition, this curved surface is directed in a direction that forms a curve when viewed on a surface substantially orthogonal to both the wall surface of the wall panel and the mounting surface of the mounting material.

  And even if a shear displacement occurs between the wall panel and the frame structure due to vibration such as an earthquake, and the wall panel is likely to be deformed in the out-of-plane direction, the torsion is offset inside the damping member. Displacement in the shear direction mainly occurs.

  For this reason, deformation in the shear direction is mainly input to the vibration damping member, and the vibration damping member functions efficiently by the deformation, and the building can be damped.

  Further, if both side edges of the wall panel are pin-supported by a stud or the like, the wall panel rotates when the frame structure is deformed. Furthermore, if the wall panel that rotates in this way is connected to the beam through the damping member, when the frame structure is deformed by an earthquake or the like, the deformation is efficiently input to the damping member, The vibration function can be demonstrated.

  Further, by providing the protruding pieces on the wall panel, it is possible to easily fix the damping member having a curved surface to each of the attachment material and the wall panel. In particular, when the mounting surface of the mounting material is a flange surface such as a beam, if the protruding piece parallel to the flange surface is provided, the damping member can be easily attached to the flange and the protruding piece.

  Furthermore, if the damping member is formed in a substantially semicircular shape in cross section and the curved surface is arranged on the wall panel side, the fixing portion is exposed on the inner side of the building and the fixing work is facilitated.

  Further, if the damping member is formed in a substantially circular shape in cross section, the resistance force against the twisting of the damping member can be increased.

  Furthermore, the damping member may be a member in which a plurality of curved surfaces are continuously formed. In this case, a damping member having various performances can be manufactured by adjusting the number of curved surfaces, the curvature, the height, and the like.

  Moreover, if it is a strip | belt-shaped damping member which has a curved surface in this way, it can be attached to various places and various damping performances can be exhibited by the attachment position and the attachment direction.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view for explaining the structure of the vibration damping structure of the building 1 according to the present embodiment. FIG. 2 is an elevation view of the building 1 as viewed from the side (in the direction of arrows AA in FIG. 3). 3 is a plan view of the first floor of the building 1.

  First, the structure of the building 1 will be described. The building 1 is a two-story detached house as shown in FIG. 2, and has a multilayer structure in which a first floor part 11 and a second floor part 12 are laminated on a foundation part 10. It has become.

  This building 1 includes a plurality of columns 133,..., A ceiling beam 132,... As a beam spanned between the upper ends thereof, and a floor beam 131,. And a box-shaped frame structure 13 formed by. The frame structure 13 becomes a frame structure when the column 133, the ceiling beam 132, and the floor beam 131 are rigidly joined. Further, a frame structure in which the floor beam 131 is omitted and the pillar 133 is erected on the foundation 10 may be used.

  Moreover, as shown in FIG. 4, between the ceiling beam 132 and the floor beam 131, a pillar 134 for attaching a wall panel to be described later is erected at a predetermined interval. The stud 134 is connected to the ceiling beam 132 at the upper end and the floor beam 131 at the upper end, but is a member installed to attach the wall panel, so that the load from the frame structure 13 is difficult to be transmitted. The end has a spring structure.

  And as this building 1 is shown by the top view of the 1st floor part 11 of FIG. 3, the outer wall is comprised by the several wall panel (2, 21, 23). That is, the corner panel 23 of L shape in plan view is arrange | positioned in the four corners of the building 1, and the general wall panel 21, ... in which a damping member is not arrange | positioned between the corner panels 23 and 23 ,. An opening 22 such as a window, etc., and a damping wall panel 2 as a wall panel connected via a damping member are arranged.

  As shown in the front view of the damping wall panel 2 seen from the outside of the building in FIG. 4, both side edges are connected to the studs 134 and 134 by bolts 2c and 2c at the approximate center in the height direction. It has become a support. Although not shown in the drawing, the general wall panel 21 is also pin-supported on both side edges by the spacers 134, 134.

  As described above, the pin-supported damping wall panel 2 whose rotation is not restrained is rocked or rotated by deformation of the frame structure 13 unless it is connected to the frame structure 13 at other locations. However, the damping wall panel 2 is connected to the ceiling beam 132 and the floor beam 131 via U-shaped dampers 4... As damping members.

  FIG. 1 is a perspective view illustrating a portion excluding both side edges connected to the studs 134 in order to explain the configuration of the damping wall panel 2.

  The damping wall panel 2 includes a rectangular face plate 2a such as a hard wood cement board, horizontal frames 2b and 2b attached to the inner wall surface of the building 1 in the horizontal direction, and the horizontal frame 2b, 2b is provided with L-shaped metal fittings 3,... Which are respectively attached with an interval in the width direction of the face plate 2a.

  The horizontal frames 2b and 2b are substantially parallel to the ceiling beam 132 and the floor beam 131, immediately below the upper edge of the face plate 2a adjacent to the ceiling beam 132 and immediately above the lower edge of the face plate 2a adjacent to the floor beam 131. It is attached.

  The L-shaped bracket 3 is a bracket that is attached to provide a protruding piece 31 that is substantially orthogonal to the face plate 2a. One side of the L-shape that is orthogonal to the protruding piece 31 is placed on the side surface of the horizontal frame 2b as shown in FIG. Fix it. That is, the L-shaped metal fitting 3 is attached to the lower horizontal frame 2b so that the protruding piece 31 protrudes in a bowl shape, and is attached to the upper horizontal frame 2b in an L shape.

  Here, the floor beam 131 is made of a steel material having a U-shape in cross section, and the upper surface of the upper flange serves as a mounting surface 131a, and the mounting surface 131a and the lower protruding piece 31 are substantially parallel to each other. . The ceiling beam 132 is also made of a steel material having a U-shape in cross section, and the lower surface of the lower flange serves as the mounting surface 132a, and the mounting surface 132a and the upper protruding piece 31 are substantially parallel to each other. And U-shaped dampers 4 and 4 are arranged between the upper and lower protruding pieces 31 and 31 and the mounting surfaces 132a and 131a, respectively.

  As shown in FIG. 6, the U-shaped damper 4 is a belt-like member obtained by forming a mild steel plate such as carbon steel or stainless steel into a semi-circular shape in cross section, and is provided with fixing portions 41 and 42 at both ends, respectively.

  The one fixing portion 41 is formed into a flat plate shape so as to be brought into contact with the protruding piece 31, and the other fixing portion 42 is brought into contact with the mounting surface 131a of the floor beam 131 (or the mounting surface 132a of the ceiling beam 132). Therefore, it is formed into a flat plate shape. Further, each of the fixing portions 41 and 42 is formed with a bolt hole 45 penetrating in the plate thickness direction. The bolt 44a is inserted into the bolt hole 45 and is tightened with a nut 44b. Fixing portions 41 and 42 are fastened to the surfaces 131a and 132a, respectively.

  The curved surface portion 43 formed between the fixed portions 41 and 42 is a surface that is substantially orthogonal to both the face plate 2a serving as the wall surface of the damping wall panel 2 and the mounting surfaces 131a and 132a (that is, the paper surface of FIG. 5). Attach it in a direction that looks like a curve. Moreover, this curved surface part 43 is arrange | positioned at the face plate 2a side, and the building inside side of the U-shaped damper 4 will be open | released.

  Next, the effect | action of the damping structure of the building 1 of this Embodiment is demonstrated.

  In the vibration damping structure of the building 1 according to the present embodiment configured as described above, the floor beam 131 and the ceiling beam 132 as the attachment members and the vibration damping wall panel 2 are connected by the U-shaped dampers 4. Has been.

  Further, the U-shaped damper 4 is provided with fixing portions 41 and 42 for attachment to the U-shaped damper 4 and a curved surface portion 43 formed between the fixing portions 41 and 42. Further, the curved surface portion 43 is in a direction in which the curved surface portion 43 becomes a curve when viewed on a surface (for example, the paper surface of FIG. 5) substantially orthogonal to both the face plate 2a of the damping wall panel 2 and the mounting surfaces 131a and 132a of the beams 131 and 132. Directed.

  Here, with reference to FIG. 6A, the result of analyzing the internal stress generated when shear deformation occurs in the U-shaped damper 4 will be described. The coordinates shown in the lower left of FIG. 6 (a) are the out-of-plane direction (in other words, the inside / outside direction of the building) where the X direction is orthogonal to the damping wall panel 2, and the Y direction is the in-plane horizontal direction (in other words, shearing) Direction), the Z direction is the vertical direction. Hereinafter, the direction with the arrow of this coordinate axis is defined as the positive direction.

First, as an input value for analysis, the upper fixing portion 41 is deformed in the positive Y direction, and the lower fixing portion 42 is deformed in the negative Y direction. Then, in the fixed portion 41 of the U-shaped damper 4 fixed by the bolt holes 45,..., Stresses P _X , P _Y , and −P _Z are generated at the left edge as viewed in FIG. Then, -P _X , P _Y , and P _Z are generated.

Here, as a result of analysis, the absolute values of the stress P _X and the stress −P _X , and the stress P _Z and the stress −P _Z are substantially equal. That is, since the stress in the X direction and the Z direction cancels each other at the left edge and the right edge of the fixed portion 41, the fixed portion 41 only moves in the positive Y direction, and the X direction (the out-of-plane direction of the damping wall panel 2). ) And Z direction (vertical direction) hardly move.

Incidentally, FIG. 6B is generated in the U-shaped damper 4 when the upper portion of the U-shaped damper 4 is deformed in the Y direction with respect to the lower surface and the fixing portion 41 is not restrained in the X and Z directions. an illustration of an image variation, in this case a stress P _R in the rotational direction on both sides of the fixed portion 41 is generated, it is considered that the twist occurs in the fixed portion 41.

  FIG. 7 is an explanatory diagram for explaining the direction of displacement and force when the damping wall panel 2 and the floor beam 131 are connected by the U-shaped dampers 4 and 4.

For example, when an earthquake or the like occurs and a displacement _{DW in the} shear direction relative to the floor beam 131 is generated in the damping wall panel 2, the axis of the displacement _DW of the damping wall panel 2 (in the thickness direction of the wall) A straight line (two-dot chain line) parallel to the displacement _DW passing near the center and a deformation axis of the U-shaped damper 4 (displacement connecting the center in the vertical direction between the fixed portions 41 and 42 between the U-shaped dampers 4 and 4. Since the straight line (two-dot chain line) parallel to _DW is off axis V, the U-shaped damper 4 on the left side of FIG. 7 has an out-of-plane force S _X from the damping wall panel 2 toward the inside of the building. The U-shaped damper 4 on the right side of FIG. 7 is subjected to an out-of-plane force -S _X from the damping wall panel 2 toward the outside of the building. However, as described above, since the upper surface of the left U-shaped damper 4 of FIG. 7 is a modification of the displacement D _W direction, the couple P _X to offset Mengairyoku S _X on the upper surface are generated. Further, since the right side of the U-shaped damper 4 is likewise an upper surface in FIG. 7 is a modification of the displacement D _W direction, the couple P _X to offset Mengairyoku -S _X on the upper surface are generated.

Then, by adjusting the shape of the U-shaped damper 4, it is possible to completely cancel out-of-plane force S _X and out-of-plane force −S _X accompanying deformation of the damping wall panel 2.

In addition, since the shear forces S _Y and S _{Y in the in-} plane direction are thereby added, the displacement D _{W in the} shear direction is efficiently input to the U-shaped dampers 4 and 4.

As described above, even if a vibration _DW in the shearing direction is generated between the damping wall panel 2 and the frame structure 13 due to vibration such as an earthquake, the U wall is likely to be deformed in the out-of-plane direction. The torsion is canceled out inside the shape dampers 4,... And deformation in the shear direction mainly occurs.

  For this reason, deformation in the shear direction is mainly input to the U-shaped damper 4, and the U-shaped damper 4 functions efficiently by the deformation, and the building 1 can be damped.

  Further, if both side edges of the damping wall panel 2 are pin-supported by the studs 134, 134, etc., the damping wall panel 2 rotates when the frame structure 13 is deformed. Furthermore, if the vibration-damping wall panel 2 that rotates in this way is connected to the floor beam 131 and the ceiling beam 132 via the U-shaped dampers 4,..., The frame structure 13 is deformed by an earthquake or the like. In addition, the deformation is efficiently input to the U-shaped dampers 4,..., And the damping function can be exhibited.

  Further, by providing the protruding piece 31 on the damping wall panel 2, the U-shaped damper 4 having the curved surface portion 43 can be easily fixed to the floor beam 131, the ceiling beam 132, and the damping wall panel 2, respectively. .

  In particular, when the mounting surfaces 131a and 132a of the floor beam 131 and the ceiling beam 132 are flange surfaces, if the protruding piece 31 parallel to the flange surface is provided, the U-shaped damper 4 can be easily formed on the flange and the protruding piece 31. Can be attached.

  Furthermore, if the U-shaped damper 4 is formed in a substantially semicircular shape in cross-section and the curved surface portion 43 is disposed on the damping wall panel 2 side, the fixing portions 41 and 42 are exposed on the inner side of the building 1. The operation | work which attaches the volt | bolt 44a and the nut 44b can be performed easily.

  Hereinafter, Example 1 of a form different from the above-described embodiment will be described. The description of the same or equivalent parts as those described in the above embodiment will be given the same reference numerals.

  FIG. 8 is a perspective view illustrating the configuration of the vibration damping structure of the building 1 according to the first embodiment, FIG. 9 is a top perspective view illustrating the detailed configuration with the O-shaped damper 6 as a vibration damping member attached, and FIG. 3 is a perspective view illustrating a configuration of an O-shaped damper 6. FIG.

  First, with reference to FIGS. 8 and 9, the damping wall panel 2 connected to the floor beam 131 and the ceiling beam 132 by the O-shaped dampers 6,. Adjacent to each other, two substantially parallel horizontal frames 2f and 2f are respectively attached.

  Further, a rectangular plate-like portion of the T-shaped bracket 5 is passed over the horizontal frames 2f and 2f, and a protruding piece 51 is formed on the T-shaped bracket 5 so as to project in a direction substantially orthogonal to the face plate 2a. ing.

  On the other hand, as shown in FIG. 10, the O-shaped damper 6 is a belt-like member obtained by forming a mild steel plate such as carbon steel or stainless steel into a substantially circular shape in cross-section, and a pair of fixing portions 61 and 62 are provided at upper and lower opposing positions. Is provided.

  The one fixing portion 61 is formed into a flat plate shape so as to be in contact with the protruding piece 51, and the other fixing portion 62 is in contact with the mounting surface 132a of the ceiling beam 132 (or the mounting surface 131a of the floor beam 131). In order to make it, it is formed into a flat plate shape. The fixing portions 61 and 62 are respectively formed with bolt holes 65 penetrating in the plate thickness direction.

  Then, as shown in FIG. 9, the bolts 64a are inserted into the respective bolt holes 65 of the fixing portions 61 and 62, and tightened with the nuts 64b, whereby the fixing portion 61 of the O-shaped damper 6 is fitted to the protruding piece 51 or the mounting surface 132a. 62 are fastened.

Thus, the O-shaped damper 6 formed in a substantially circular cross-sectional view can increase the resistance to twisting. Here, FIG. 10 shows the directions of the shearing forces S, -S acting on the O-shaped damper 6 and the stresses P _C ,. From this figure, it can be seen that out-of-plane torsion hardly occurs due to deformation of the O-shaped damper 6 itself.

  When the building 1 vibrates due to an earthquake or the like, as shown in FIG. 9, the damping wall panel 2 swings as indicated by the dashed-dotted arc around the bolts 2c and 2c supported by the pins. Due to this oscillation, deformation is input to the O-shaped dampers 6 and 6, and vibration energy is absorbed.

  On the other hand, the axis passing through the center of the O-shaped dampers 6 and 6 (straight line of the two-dot chain line on the near side in FIG. 9) and the axis line of the damping wall panel 2 (two-dot chain line on the back side in FIG. 9) are Since the axis is shifted in the out-of-plane direction (inside / outside of the building), a force in the out-of-plane direction acts on the O-shaped dampers 6 and 6, but the O-shaped dampers 6 and 6 themselves are twisted. Since no out-of-plane force is generated, the input to the O-shaped dampers 6 and 6 mainly deforms in the shear direction (in-plane direction) and absorbs vibration energy, thereby damping the building 1. it can.

  Other configurations and operational effects are substantially the same as those in the above-described embodiment, and thus description thereof is omitted.

  Hereinafter, Example 2 of a form different from the above-described embodiment or Example 1 will be described. The description of the same or equivalent parts as those described in the above embodiment or Example 1 will be given the same reference numerals.

  In the second embodiment, as shown in FIG. 11, a vibration damping structure of a building 1 in which an S-shaped damper 7 as a vibration damping member in which curved surfaces whose directions are opposite to each other is continuously formed will be described.

  FIG. 12 is a perspective view for explaining the configuration of the lower part of the damping wall panel 2 connected to the floor beam 131 by the S-shaped dampers 7 and 7. Although illustration of the ceiling beam 132 side is omitted, the configuration is substantially the same as that of the floor beam 131 side.

  Middle pillars 135 and 135 are erected on the floor beam 131 in accordance with the width of the damping wall panel 2. The middle column 135 is a structural member that receives a load from the floor beam 131 to which the end portion is coupled, and the flanges 131a and 131c of the floor beam 131 to which the middle column 135 is coupled are reinforced by the reinforcement bolts 131b and 131b. The

  Further, support metal fittings 2e and 2e are fixed to the inner side surfaces at substantially the center of the middle pillars 135 and 135, and an intermediate frame 2d attached to the face plate 2a of the damping wall panel 2 and the support metal fittings 2e and 2e are bolts 2c. , 2c, the damping wall panel 2 is pin-supported.

  A horizontal frame 2g is attached to the floor beam 131 substantially parallel to the floor beam 131 immediately above the lower edge of the face plate 2a adjacent to the floor beam 131. Furthermore, the fixing brackets 8 are attached to the horizontal frame 2g at intervals in the width direction of the face plate 2a.

  On the other hand, as shown in FIG. 11, an S-shaped damper 7 as a vibration damping member is a band-shaped member formed by forming a mild steel plate such as carbon steel or stainless steel into a substantially S shape in cross-section, and has fixed portions 71, 72 is provided.

  The one fixing portion 71 is formed into a flat plate shape parallel to the fixing bracket 8, and the other fixing portion 72 is brought into contact with the mounting surface 131 a of the floor beam 131 (or the mounting surface 132 a of the ceiling beam 132). Therefore, it is formed into a flat plate shape. The fixing portions 71 and 72 are respectively formed with bolt holes 75 penetrating in the plate thickness direction.

  And between this fixing | fixed part 71 and 72, as shown in FIG. 11, the curved surface parts 73a and 73b from which two directions are exactly opposite are formed continuously. That is, the upper curved surface portion 73a is formed in a substantially U shape in cross section with a curved surface having a radius R that bulges toward the inside of the building, and the lower curved surface portion 73b bulges toward the damping wall panel 2 side. Since it is formed in a substantially U shape in a sectional view having a curved surface with a radius R, it has an inverted S shape as seen in FIG.

  The curved surface portions 73a and 73b can adjust characteristics such as elastic stiffness, yield point, secondary stiffness, ultimate strength, and repeated strength by adjusting the width W, depth H, and height L. Furthermore, these characteristics can be adjusted by increasing the number of curved surface portions 73a and 73b.

  Further, as shown in FIG. 12, the S-shaped damper 7 has a bolt 73 a in the bolt hole 75 of the fixing portion 71 with respect to each of the fixing brackets 8 and 8 attached to the inside of the building of the damping wall panel 2. Insert and tighten. Moreover, the fixing | fixed part 72 is fastened with respect to the attachment surface 131a of the floor beam 131 with the volt | bolt 73a and the nut 73b.

When the displacement _DW in the shearing direction is generated between the damping wall panel 2 and the frame structure 13 due to an earthquake or the like in the S-shaped damper 7 thus installed, the direction of the direction indicated by the one-dot chain line in FIG. The displacement acts on the respective fixing portions 71 and 72.

  As a result, deformation is input to the curved surface portions 73a and 73b and the vibration energy is absorbed, whereby the damping function of the S-shaped damper 7 is exhibited. In this case, by adjusting the number of curved surface portions, the curvature (radius R), the width W, the depth H, the height L, and the like, vibration damping members having various performances can be manufactured.

  The S-shaped damper 7 can be attached to the damping wall panel 2 and the floor beam 131 (ceiling beam 132) with a small number of members.
