[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a damping wall structure that is interposed in a building and suppresses vibration.
[0002]
[Prior art]
As a vibration control structure for a building, Japanese Patent Laid-Open No. 2000-303714 is configured by interposing a fiber-reinforced hardened material between a building frame and a precast concrete board (hereinafter referred to as a PC board) provided as a structure. A damping structure is disclosed. Specifically, a PC plate forming a wall surface is arranged in a construction surface surrounded on all sides by beams and columns forming a frame, and between the upper and lower beams opposite to the upper and lower peripheral surfaces of this PC plate. In each case, a fiber reinforced mortar is interposed. In this vibration damping structure, when a relative displacement in the horizontal direction occurs between beams positioned above and below due to an earthquake or the like, the fiber reinforced mortar interposed between the PC plate and the beam is deformed in the shear direction. Since this fiber reinforced mortar has high toughness, vibration energy is absorbed by its hysteresis damping characteristics, the relative displacement between the PC plate and the beam is suppressed, and the vibration of the frame is suppressed.
[0003]
[Problems to be solved by the invention]
However, in the above-mentioned conventional vibration damping structure, the PC board provided through the fiber reinforced mortar in the construction surface is a structural body. Therefore, the PC board has its own weight and the weight of the load as well as wind pressure and earthquake. Rigidity and strength that can resist force are required. Therefore, although the above-mentioned vibration damping structure is applied to a bearing wall or the like, since the arrangement of the bearing wall is limited due to the structure, the degree of freedom of design is low and it is difficult to obtain a desired damping performance.
Moreover, since the fiber reinforced mortar interposed between the PC plate and the beam forming the wall surface has poor resilience, there is a problem that it is difficult to use repeatedly.
[0004]
Therefore, the present invention has been made in view of such conventional problems, and the damping structure uses a non-structural plate material that is installed in a large number of buildings, and bears a slight load to cover the quantity. The purpose of the present invention is to provide an inexpensive damping wall structure that is not limited in installation location.
[0005]
[Means for Solving the Problems]
This onset bright in order to achieve the above object, there is provided a damping wall structure in which the glass sheet is a non-structural member via a damping member made of a viscoelastic body in a part of the building,
The said plate glass is provided in a part of said building through the said damping member with which the upper and lower edge part of the side surface was mounted | worn .
[0006]
According to the present invention, since a viscoelastic body is interposed between a part of the building and the plate glass , vibration energy input to the building due to an earthquake or the like is absorbed by the viscosity of the viscoelastic material, so that vibration Can be attenuated.
[0007]
Furthermore, the glass sheet than Ru provided numerous buildings, the load acting on each of the glass sheets is dispersed by the vibration. Therefore , the plate glass which is a non-structural member can be used , and further, the structural strength of the building is not lowered depending on the arrangement position of the plate glass . Thus with the arrangement position of the glass sheet can be constrained without freely laid and does not require new structural member with high have rigidity and strength can be reduced construction costs.
[0008]
In addition, since the vibration damping member is attached to the plate glass from its side surface , shear deformation occurs in the vibration damping member according to the displacement of the plate glass , and the vibration energy is efficiently absorbed with a sufficient vibration damping function. be able to.
[0009]
Furthermore, since the non-structural member is composed of a glass sheet, in a glass window of a building can apply this damping wall structure, it can be lighting while providing a damping function. In particular, a glass window can be provided with a vibration control function even in a building whose wide outer peripheral area is covered with glass in consideration of openness and daylighting. Therefore, it is not necessary to use a wall material that shields the construction surface in order to provide a vibration damping function, and a more open space can be realized.
[0010]
A part of the building may be an outer wall portion, a partition portion, a beam or a column between the buildings.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an exploded perspective view showing a first embodiment of the damping wall structure of the present invention.
[0012]
As shown in FIG. 1, the damping wall structure of the first embodiment of the present invention includes two adjacent columns 12, two upper and lower beams 14 bridged between them, the columns 12 and the beams. The plate glass 18 provided on the construction surface formed by 14, the support member 20 for supporting the plate glass 18 to the column 12 and the beam 14, and a vibration damping member interposed between the support member 20 and the plate glass 18 are formed. And viscoelastic body 16. In the present embodiment, for example, Scotchdamp (registered trademark: VEM manufactured by Sumitomo 3M Limited) is used as the preferred viscoelastic body 16.
[0013]
The plate glass 18 is formed to be slightly smaller than the area of the construction surface to allow deformation of the building frame due to an earthquake or the like, and on both sides thereof, near the center of the four edges that are parallel to the pillar 12 and the beam 14, respectively. The viscoelastic body 16 is adhered to the substrate.
[0014]
The support member 20 is made of an L-shaped steel material, and one plate portion forming the L shape is bonded to the plate glass 18 by the viscoelastic body 16, and the other plate portion is fixed to the column 12 and the beam 14 by known means. Has been.
[0015]
That is, the edge of the glass plate 18 provided in the surface composed of the column 12 and the beam 14 is sandwiched between the support members 20 from both sides via the viscoelastic body 16, and the support members 20 are connected to the columns. The damping wall 10 is formed by being fixed to 12 and the beam 14.
[0016]
When vibration is input to the building due to an earthquake, wind pressure, or the like, the upper and lower beams 14 are displaced between layers, the surface of the structure is sheared and deformed in the horizontal direction, and the plate glass 18 is rotated in the vertical direction. At this time, the viscoelastic body 16 interposed between the support member 20 provided on the column 12 and the beam 14 and the plate glass 18 undergoes hysteresis deformation in the shearing direction and absorbs vibration energy, so that vibration can be attenuated. . In particular, since many non-structural members such as plate glass 18 are provided in the building, it is possible to disperse the load acting on each non-structural member due to vibration, thereby reducing the burden on each non-structural object. Furthermore, the structural strength of the building is not reduced by the position of the plate material.
[0017]
Further, since the plate glass 18 constituting the plate material is mounted from the side surface by the viscoelastic body 16 bonded to the wall surface, shear deformation is likely to occur in the viscoelastic body 16 according to the displacement of the plate glass 18, and sufficient vibration suppression is achieved. It has a function and can absorb vibration energy efficiently.
[0018]
Furthermore, since the plate material is the plate glass 18, for example, when this damping wall structure is applied to the outer wall of a building, it is possible to provide a damping function while ensuring lighting in the building. In particular, even if almost the entire surface is covered with glass as in recent buildings, the glass outer wall can be provided with a vibration control function, so the glass window is closed only to provide a vibration control wall. It is not necessary, and sufficient lighting can be secured and a good appearance can be maintained.
[0019]
As a modification of the first embodiment, even if the viscoelastic body 16 is provided on both sides of the plate glass 18 over the entire circumference as shown in FIG.
[0020]
Other embodiments of the present invention will be described below, but the overall schematic configuration is substantially the same as the configuration of the first embodiment described above. Therefore, the same reference numerals are given to the same members, and the differences are noted. Only explained.
[0021]
As shown in FIGS. 3 to 5, in the second embodiment of the present invention, the viscoelastic body is attached to the frame body 22 that is fitted and fixed to the construction surface surrounded by the pillar 12 and the beam 14 of the building 1. The wall surface formed by the plate glass 18 is bonded via 16. In this damping wall structure, the glass wall unit 24 in which the frame body 22 and the plate glass 18 are integrated via the viscoelastic body 16 can be assembled in advance in a factory or the like and carried into the construction site. As a result, the workability can be reduced, the workability can be improved, the work period can be shortened, and the plate glass 18 can be easily replaced.
[0022]
The glass wall unit 24 may be formed by sandwiching the viscoelastic body 16 on both surfaces of the plate glass 18 using two frames.
[0023]
Furthermore, since the damping wall 10 does not have a use as a structure, it can be laid out at a free position regardless of the frame structure. In particular, by making the damping wall into parts as described above, it can also be applied as the partition wall 26 as shown in FIG. 6, and can be moved to a desired place as required.
[0024]
In addition, as shown in FIG. 7, if the frame 22 and the edge of the blindfold lattice 28 overlap with each other between the small beams 14a, the vibration control function can be achieved without impairing the atmosphere of the building even in a Japanese style building. Can be provided.
[0025]
8 and 9 show a third embodiment, in which the damping wall structure of the present invention is suspended from the housing 60 as a curtain wall 58. At this time, when the viscoelastic body 16 is interposed between the upper and lower wall panels 54 and 56 and the plate glass 18 and is carried into the construction site as a unit, the installation work at the site is facilitated and the state is separated. If it is carried in at the site, transportation work and handling at the site are easy and easy to handle.
[0026]

This arrange | positions the some glass plate 18 along the drooping wall 30 and the waist wall 32 between the adjacent pillars 12. The support member 20 is adhered to the upper and lower edges of each glass plate 18 via the viscoelastic body 16 by the viscoelastic body 16, and the support member 20 is fixed to the hanging wall 30 and the waist wall 32, respectively. The vibration control function can be provided without impairing the feeling of opening by the double window 34. Here, if the setting block 50 is interposed between the plate glass 18 and the waist wall 32 and supported from under the plate glass 18, the plate glass 18 can be maintained at a position away from the waist wall 32 during construction, so that the construction is easy. Can do. This setting block 50 is applicable not only to this embodiment but also to other embodiments.
[0027]
FIGS. 12-14 shows other embodiment of the fixing method of the plate glass 18 in the said embodiment, and it uses the bolt 36 which penetrates the plate glass 18, and is L-shaped support tool from both surfaces of the plate glass 18 for every bolt 36. 38 is used to support the upper and lower beams 14.
[0028]
The plate glass 18 is provided with a plurality of through-holes 40 penetrating the wall surface along the edge of the plate glass 18. The through hole 40 has a diameter sufficiently larger than the outer diameter of the threaded portion of the bolt 36, and an annular buffer ring 42 interposed between the bolt 36 and the inner peripheral surface thereof is inserted therein.

【The invention's effect】
As described above, in the damping wall structure of the present invention, vibrations can be suppressed because the damping member is interposed between a part of the building and the plate material.
[0034]
Since plate glass , which is a non-structural member provided in a building, is used as a plate material constituting the damping wall, a new structure is not required, so that the construction cost can be reduced. Furthermore, since a large number of damping walls are installed, the load is distributed and the load acting on each is light, so that the damping walls can be laid out freely.
[0035]
Further, since the viscoelastic member is mounted from the side surface, the vibration damping member undergoes shear deformation according to the displacement of the plate glass , and the vibration energy can be efficiently absorbed.
[0036]
Furthermore, since the non-structural member is composed of a plate glass can constitute a glass window having a damping function, it is possible to form a space with daylighting possible airy.
