Abstract

<P>PROBLEM TO BE SOLVED: To obtain a wall structure with a vibration control device, which is excellent in work efficiency. <P>SOLUTION: The vibration control device 32 is arranged between a ceiling girder 16 and a floor girder 20. A laterally sliding member 64 is slidably engaged with a horizontal bar 54C arranged inside a wall. A wooden brick 66 for fixing an interior wall panel is fitted to the laterally sliding member 64. When an exterior wall panel 58 including the attached laterally sliding member 64 having the wooden brick 66 fitted thereto in advance is fitted to side faces of the girders first, and the vibration control device 32 is then fitted, it is expected that the vibration control device 32 may interfere with the wooden brick 66. However, when the laterally sliding member 64 (the wooden brick 66) is displaced from the position of arrangement of the vibration control device 32, the vibration control device 32 can be easily fitted to the ceiling girder 16 and the floor girder 20 even after the wooden brick 66 is fitted. Further, when the laterally sliding member 64 is displaced, the wooden brick 66 can be fitted so as to avoid interfering between the vibration control device 32 and wooden brick 66 even after the vibration control device 32 is fitted. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT

The upper portion of the bracket 48 and the upper plate portion 16A of the ceiling beam 16 are fixed with bolts (not shown), and the lower portion of the bracket 48, the lower plate portion 16B of the ceiling beam 16 and the first damper mounting member 38A are not shown. Are fixed to each other.

  A damper 36 is horizontally disposed between the first damper mounting member 38A and the second damper mounting member 38B. One end of the damper 36 is connected to the first damper mounting member 38A via a pin 50. The other end is connected to the second damper mounting member 38B via the pin 52.

The damper 36 is a relative displacement between the first damper mounting member 38A and the second damper mounting member 38B (the relative displacement in the axial direction of the floor girder 20 and the ceiling girder 16 in the direction of the arrow A in FIG. Any known damper such as an oil damper or a viscoelastic damper may be used as long as it generates a damping force at the time.
It should be noted that the upper end portion of the fixed frame 34 is placed on the lower plate portion 16B of the ceiling girder 16 from the front and back sides of FIG. 2 so as to prevent falling down to the outside of the wall surface of the fixed frame 34 (the front and back sides in FIG. 2). A pair of guide plates 53 arranged so as to be sandwiched are attached.

(Wall structure)
2-5, the outer wall panel 58 comprised including the frame-shaped outer wall frame 54 and the exterior | packing material 56 is arrange | positioned at the outdoor side of the ceiling girder 16 and the floor girder 20.
The outer wall frame 54 is attached to the side surfaces of the ceiling girder 16 and the floor girder 20 on the outdoor side, and includes a plurality of vertical beams 54A extending in the vertical direction so as to bridge the ceiling girder 16 and the floor girder 20. It includes a horizontal beam 54B that extends in the horizontal direction so as to span the ends of the beam 54A and is connected to the vertical beam 54A, and a horizontal beam 54C that extends in the horizontal direction so as to bridge the middle part of the vertical beam 54A. It is configured in a frame shape. The exterior material 56 is fixed to at least the vertical beam 54A and the horizontal beam 54B.
In this embodiment, the vertical beam 54A and the horizontal beam 54B of the outer wall frame 54 are fixed to the side surfaces of the ceiling beam 16 and the floor beam 20 by bolts or the like (not shown).
As shown in FIG. 3, the horizontal rail 54 </ b> C of the outer wall frame 54 is separated so as not to contact the fixed frame 34 of the vibration control device 32.

As shown in FIG. 4, the vertical beam 54A and the horizontal beam 54C according to the present embodiment are formed of a steel plate having a C-shaped cross section, and the horizontal beam 54B is formed of a steel plate having a U-shaped cross section.
The vertical beam 54A on one side and the vertical beam 54A on the other side with respect to the damping device 32 are provided in such a direction that the C-shaped opening sides face each other. Further, the horizontal rail 54C is arranged so that the C-shaped opening faces the indoor side (inner wall panel side).

  A block-like vertical slide member 60 is slidably engaged with the vertical beam 54A. The vertical slide member 60 is slidably arranged inside the vertical beam 54A and has a trapezoidal insertion portion 60A in side view, and a mounting portion 60B that protrudes outside the vertical beam 54A through a C-shaped opening and rectangular in side view. And have.

The vertical slide member 60 can be formed of wood, synthetic resin, metal, or the like.
The width of the insertion portion 60A (the width of the base of the trapezoid) is set to be larger than the C-shaped opening width of the vertical beam 54A, and does not come out to the C-shaped opening side. Therefore, the vertical slide member 60 in which the insertion portion 60A is inserted into the vertical beam 54A is movable only along the longitudinal direction of the vertical beam 54A without being detached from the vertical beam 54A. The side view shape of the insertion portion 60A may be a shape other than a trapezoid, such as a rectangle.

  Since a notch 55 is formed on the lower end side of the vertical beam 54A so as to be cut out over a substantially half width, the insertion portion 60A of the vertical slide member 60 is inserted into the vertical beam 54A via the notch 55. Can be inserted inside.

  The attachment portion 60B is inserted into the end portion of the horizontal rail 54C, and the horizontal rail 54C and the attachment portion 60B are fixed to each other by a nail 62 or the like.

  Therefore, the horizontal beam 54C having the vertical slide member 60 at the end is slidable along the vertical beam 54, that is, slidable in the vertical direction before the vertical slide member 60 is fixed to the vertical beam 54. Yes.

  A block-shaped horizontal slide member 64 having substantially the same shape as the vertical slide member 60 is slidably engaged with the horizontal rail 54C. The horizontal slide member 64 is slidably disposed inside the horizontal beam 54C and has a trapezoidal insertion portion 64A in side view, and a mounting portion 64B that protrudes outside the horizontal beam 54C through a C-shaped opening and has a rectangular side view. And have.

  The width of the insertion portion 64A (the width of the base of the trapezoid) is set to be larger than the C-shaped opening width of the horizontal rail 54C, and is prevented from coming out to the C-shaped opening side. Therefore, the horizontal slide member 64 in which the insertion portion 64A is inserted into the horizontal beam 54C is movable only along the longitudinal direction of the horizontal beam 54C without detaching from the horizontal beam 54C.

  In addition, since the vertical slide member 60 and the horizontal slide member 64 of this embodiment are fixed to the horizontal rail 54C using a nail, they are formed of a synthetic resin so that the nail can be driven. It can also be formed of materials other than synthetic resins such as.

As shown in FIGS. 3 and 4, a block-like wooden brick 66 made of wood is attached to the end surface of the attachment portion 64 </ b> B in the horizontal slide member 64.
As shown in FIG. 5, in this embodiment, the wooden brick 66 is attached to the horizontal slide member 64 with three nails 68, and the central nail 68 penetrates the wooden brick 66 and the horizontal slide member 64. The nails 68 on both sides in the vertical direction penetrate the wooden brick 66 and the horizontal rail 54C and are driven into the horizontal slide member 64.

  As shown in FIG. 3, an inner wall panel 70 made of a wood frame, a plywood, a gypsum board, or the like is disposed on the outdoor side (the direction of the arrow OUT) of the ceiling beam 16 and the floor beam 20. It is fixed to the wooden brick 66 by a nail or the like (not shown).

(Function)
Next, the effect | action of the building unit 12 of this embodiment is demonstrated.
When the building unit 12 is shaken by an earthquake, wind pressure, or the like, the ceiling girder 16 is displaced in the beam axis direction with respect to the floor girder 20 on the foundation side. However, the control unit disposed between the ceiling girder 16 and the floor girder 20 is not suitable. The seismic device 32 suppresses the displacement and reduces the shaking of the building unit 12.

Here, since the fixed frame 34 is fixed to the floor beam 20, the fixed frame 34 does not move relative to the floor beam 20 even if the building unit 12 is shaken.
When the ceiling girder 16 is displaced in the beam axis direction with respect to the floor girder 20 on the foundation side, the outer wall frame 54 is deformed into a parallelogram.
Considering the floor girder 20 as a reference, the displacement amount (horizontal direction) of the outer wall frame 54 increases in proportion to the distance from the floor girder 20 as it goes from the floor girder 20 to the upper ceiling girder 16.

  Therefore, when the building unit 12 is shaken, each horizontal beam 54C is displaced in the same direction as the ceiling beam 16 but is closer to the ceiling beam 16 than the displacement amount of the horizontal beam 54C on the side closer to the floor beam 20. The displacement amount of the side crosspiece 54C becomes larger.

Since the wooden brick 66 is attached to the side rail 54C toward the indoor side, when the horizontal rail 54C is displaced, the wooden brick 66 is naturally displaced in a similar manner.
For this reason, when the wooden brick 66 is disposed close to the fixed frame 34, the wooden brick 66 may interfere with the fixed frame 34 depending on the magnitude of shaking.

  Further, when a plurality of inner wall panels 70 are provided in the lateral direction, the position of the wooden brick 66 for fixing the inner wall panel 70 can be determined at the construction site in consideration of the seam of the inner wall panel 70, workability, and the like. preferable.

  In the building unit 12 of this embodiment, the outer wall panel 58 and the vibration control device 32 are attached to the ceiling beam 16 and the floor beam 20 first, and then the inner wall panel 70 is attached. Any of the outer wall panel 58 and the vibration control device 32 may be attached to the ceiling beam 16 and the floor beam 20 first.

  In the outer wall panel 58, the wooden brick 66 is fixed in advance only to the horizontal slide member 64 (fixed only by the single nail 68 in the center of FIG. 5 and not fixed to the horizontal rail 54C). By doing so, the wooden brick 66 can be moved in the horizontal direction.

  For example, when the inner wall panel 70 is attached at the construction site, the wooden brick 66 is controlled according to the position of the seam, the distance from the floor beam 20 to the horizontal beam 54C related to the amount of displacement of the horizontal beam 54C, and the like. The position is adjusted by sliding the wooden brick 66 so as not to interfere with the seismic device 32. After the position adjustment is completed, the wooden brick 66 is fixed to the horizontal rail 54C and the horizontal slide member 64 with two nails 68.

  More specifically, as described above, the amount of displacement of the side beam 54C closer to the ceiling beam 16 is larger than the amount of displacement of the side beam 54C closer to the floor beam 20, so that the ceiling beam 16 The distance A from the wooden brick 66 attached to the side beam 54C closer to the fixed frame 34 to the fixed frame 34 than the distance B from the wooden brick 66 attached to the side beam 54C closer to the floor beam 20 to the fixed frame 34 Is set so that the wooden brick 66 does not interfere with the fixed frame 34 of the vibration control device 32 when the building unit 12 is shaken.

  In the present embodiment, not only the horizontal position adjustment of the wooden brick 66 but also the vertical position adjustment can be performed. In the present embodiment, the vertical slide member 60 attached to the end of the horizontal beam 54C is engaged with the vertical beam 54A so as to be movable in the vertical direction. When the inner wall panel 70 is attached at the construction site without fixing, the horizontal beam 54C is moved up and down to adjust the vertical position of the wooden brick 66, and then the vertical slide member 60 is fixed to the vertical beam 54A with a nail or the like. The inner wall panel 70 may be fixed to the wooden brick 66 with a nail or the like.

  Moreover, since the horizontal slide member 64 to which the wooden brick 66 is attached can be adjusted in the vertical direction and the horizontal direction as described above, before the damping device 32 is attached to the ceiling beam 16 and the floor beam 20. The wooden brick 66 can be attached to the horizontal slide member 64.

  Therefore, when the outer wall panel 58 in which the wooden brick 66 is previously attached to the lateral slide member 64 is first attached to the side surface of the beam and then the damping device 32 is to be attached, the damping device 32 interferes with the wooden brick 66. However, in such a case, if the lateral slide member 64 (wood brick 66) is shifted from the position where the vibration control device 32 is disposed, the vibration control device 32 can be mounted on the ceiling even after the wooden brick 66 is attached. It can be easily attached to the girder 16 and the floor girder 20.

  Of course, even after the damping device 32 is attached, the wooden brick 66 can be attached so that the wooden brick 66 does not interfere with the damping device 32 by shifting the position of the lateral slide member 64.

  Further, if the wooden brick 66 is fixed as in the prior art, the designed clearance may not be obtained with the vibration control device 32 due to the influence of the processing accuracy of the member and the assembly accuracy of the member. However, in such a case, if the position of the wooden brick 66 cannot be adjusted, there is a possibility that the mounting of the inner wall panel 70 may be hindered. On the other hand, in this embodiment, since the position of the wooden brick 66 can be freely adjusted before attaching the inner wall panel 70, there is no possibility that the attachment of the inner wall panel 70 will be hindered as in the prior art.

[Second Embodiment]
Next, a second embodiment will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the same structure as 1st Embodiment, and the description is abbreviate | omitted. Here, an example in which a heat insulating material is arranged between the outer wall panel 58 and the inner wall panel 70 will be described.

In the present embodiment, as shown in FIG. 6, the inner wall panel 70 is fixed after the heat insulating material 72 is attached to the back side (the side facing the outer wall panel 58) of the inner wall panel 70.
As the heat insulating material 72 used in the present embodiment, a conventionally known material having flexibility such as rock wool and glass wool can be used.

  Although it arrange | positions so that the clearance gap between the outer wall panel 58 and the inner wall panel 70 may be filled, since the inner wall panel 70 is directly attached to the wooden brick 66, the heat insulating material 72 has the escape hole 74 for letting the wooden brick 66 escape. Is formed.

  As described in the first embodiment, in order to adjust the position of the wooden brick 66 at the construction site, the escape hole 74 is formed corresponding to the position of the wooden brick 66 after adjusting the position of the wooden brick 66. Will do. After adjusting the position of the wooden brick 66, the clearance hole 74 is formed corresponding to the position of the wooden brick 66, so that it can be formed with a minimum size, and the amount of cutting the heat insulating material 72 can be minimized. High heat insulation performance can be obtained.

  In this embodiment, the inner wall panel 70 to which the heat insulating material 72 is attached is fixed to the wooden brick 66. However, after the heat insulating material 72 is arranged between the beams, the inner wall panel 70 is fixed to the wooden brick 66. Also good.

[Third Embodiment]
Next, a third embodiment will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the same structure as embodiment mentioned above, and the description is abbreviate | omitted.
As shown in FIG. 7, the lateral slide member 64 of the present embodiment is provided with a non-slip 76 made of a material having a friction coefficient larger than that of the lateral slide member 64 on the surface in contact with the lateral rail 54 </ b> C.

  As the non-slip 76, for example, a rubber sheet, a synthetic resin sheet, a coating film in which a synthetic resin is dissolved in a solvent (for example, an adhesive) and then dried can be raised. It is sufficient that the sliding member 64 is less slippery than at least the lateral sliding member 64 alone, and other forms may be used.

In the case of this embodiment, the horizontal slide member 64 which fixed the wooden brick 66 with the nail etc. beforehand is produced, and this is inserted from the edge part of the horizontal crosspiece 54C.
By providing the non-slip 76 in contact with the inner surface of the horizontal beam 54C, the horizontal slide member 64 can be made difficult to move. After adjusting the position of the wooden brick 66, the wooden brick 66 can be moved with a nail or the like. In addition, the inner wall panel 70 can be fixed to the wooden brick 66. If the side slide member 64 does not have the anti-slip 76, the wooden brick 66 may be displaced in the wall when the inner wall panel 70 is positioned. There is a concern that it will be impossible to fix.

In the present embodiment, since the horizontal slide member 64 is not fixed to the horizontal beam 54C with a nail or the like, if the building unit 12 is shaken and the fixed frame 34 interferes with the wooden brick 66, the wooden brick 66 is It is possible to absorb an impact caused by moving and interfering with the fixed frame 34.
In the present embodiment, the anti-slip 76 is provided on the lateral slide member 64, but the anti-slip 76 may be provided on the vertical slide member 60 in some cases.

[Fourth Embodiment]
Next, a fourth embodiment will be described.
Although not shown, in the present embodiment, the lateral slide member 64 is formed of an elastic material. As the elastic material, rubber, flexible synthetic resin, or the like can be used.

  The advantage of forming the horizontal slide member 64 from an elastic material is that, for example, when the building unit 12 is shaken and the displaced wooden brick 66 interferes with the fixed frame 34, the horizontal slide member that supports the wooden brick 66 is supported. 64 is elastically deformed, so that at least the deformation portion moves the fixed portion of the wooden brick 66 and the inner wall panel 70, so that stress concentration on the fixed portion of the wooden brick 66 and the inner wall panel 70 is suppressed, Damage to the fixed part can be suppressed.

Further, by forming the vertical slide member 60 and the horizontal slide member 64 with an elastic material such as rubber, the members themselves become non-slip, and the anti-slip 76 described in the third embodiment can be made unnecessary.
The vertical slide member 60 may be formed of an elastic material.

[Other Embodiments]
In the above embodiment, the wooden brick 66 is attached to the horizontal beam 54C via the horizontal slide member 64. However, the wooden brick 66 may be attached to the vertical beam 54A, or the wooden brick attached to the vertical beam 54A. The inner wall panel 70 may be fixed to 66.
In the above embodiment, steel bars having a C-shaped cross section are used for the vertical beam 54A and the horizontal beam 54C. However, the cross-sectional shape of the material used for the vertical beam 54A and the horizontal beam 54C is a shape other than the C shape. May be. When the cross-sectional shapes of the vertical beam 54A and the horizontal beam 54C are changed, the shapes of the vertical slide member 60 and the horizontal slide member 64 are also slidable with respect to the vertical beam 54A and the horizontal beam 54C. Needless to say, it is changed in accordance with the cross-sectional shapes of the vertical beam 54A and the horizontal beam 54C.
In the above embodiment, the fixed frame 34 of the vibration control device 32 is attached to the floor girder 20, but the vibration control device 32 may be disposed upside down and the fixed frame 34 may be attached to the ceiling girder 16.
