Description

  The present invention relates to a vibration control wall that reduces the response of structures to earthquakes and winds, improves safety and comfort, and ensures lighting.

Generally, steel braces and RC seismic walls are used as structural elements for improving the rigidity and proof strength of the column-beam frame that constitutes a building, regardless of whether they are newly constructed or modified.
However, these structural elements obstruct the field of view and are disadvantageous in terms of aesthetics and lighting, which sometimes hinders the design with high design.

Therefore, in Patent Document 1, as shown in FIG. 6, a damping wall is disclosed in which a damping wall 101 is configured from a light transmitting portion 110 and an attenuation portion 120 to ensure lighting and aesthetics. . Here, the light transmissive part 110 is composed of a tempered glass 111 which is a light transmissive plate having rigidity, and the attenuation part 120 includes an outer wall steel plate 122 having a substantially U-shaped cross section and the outer wall steel plate 122. And the viscoelastic material 121 filled in the gap between the outer wall steel plate 122 and the inner wall steel plate 123. The lower end of the light transmissive part 110 is fixed to the upper part of the attenuation part 120 via the coupling means 112, and the upper end of the light transmissive part 110 is the steel plate of the fixing means 130 fixed to the beam 103 via the coupling means 113. It is fixed to 132. Moreover, the attenuation | damping part 120 has the lower end surface of the outer wall steel plate 122 fixed to the floor slab 104. FIG.
Japanese Patent Laid-Open No. 2001-32567 ([0020]-[0027], FIGS. 1 to 3)

  However, the conventional damping wall 101 may damage the attenuation part 120 and the light transmissive part 110 when an external force exceeding the capacity of the attenuation part 120 is applied. In addition, when the height of the outer wall steel plate 122 and the inner wall steel plate 123 is increased to increase the installation area of the viscoelastic material 121 for the purpose of ensuring high attenuation performance, the area of the light transmissive portion 110 is reduced, and the lighting is performed. It will impair the sex and aesthetics. Further, depending on the strength, the connecting means 112 for connecting the inner wall steel plate and the tempered glass may be large, and there is also a problem that the area for blocking the daylighting and the view is widened.

  The present invention aims to solve the above-mentioned problems, and an object thereof is to provide a vibration control wall that is excellent in daylighting and aesthetics as well as a vibration control function.

  In order to solve the above-mentioned problem, the invention according to claim 1 is characterized in that a damping mechanism for reducing a response of a building due to a disturbance such as an earthquake or a wind, a limiting mechanism for limiting an input size, a predetermined strength, A damping wall comprising a rigid wall body portion, wherein the wall body portion is made of a light transmissive material.

  Such a damping wall efficiently attenuates the force applied to the building by the damping mechanism, and it is possible to ensure daylighting and aesthetics by configuring the wall body portion with a light transmissive material. Moreover, since the wall part has the predetermined | prescribed intensity | strength and rigidity according to the damping performance which a damping mechanism has, it will remain in an elastic range even in the end. Furthermore, since it has a restricting mechanism that restricts input, a force greater than the strength of the damping wall is not applied, and the damping mechanism and the wall part are not damaged.

  The invention according to claim 2 is the damping wall according to claim 1, wherein one of the damping mechanism and the limiting mechanism is between the lower part of the upper frame of the installation floor and the wall part. The other is characterized in that it is installed between the lower housing and the wall of the installation floor.

  Such a damping wall is installed in the structure where the damping wall is constructed by installing the damping mechanism and the limiting mechanism apart from each other in the vertical direction. Because it fits in, or slightly protrudes, you don't have to be conscious of these mechanisms that block the field of vision, and you can feel open and feel the room wide. Here, the upper frame refers to a frame that forms a building such as a ceiling slab on the floor where the vibration control wall is installed or an upper beam member, and the lower frame is, for example, a floor slab or lower wall on the floor where the vibration control wall is installed. A frame such as a beam member on the side is shown.

  A third aspect of the present invention is the damping wall according to the first or second aspect, wherein the damping mechanism is formed by alternately laminating viscoelastic bodies and steel plates in the vertical direction. It is said.

Such a damping wall can further enhance the damping effect on the force acting on the building by stacking a plurality of viscoelastic bodies. Further, by laminating the viscoelastic bodies horizontally, it is possible to increase the area of the viscoelastic body and the light transmitting region without increasing the height of the damping mechanism. In addition, since the viscoelastic bodies are stacked horizontally, it is possible to cope with vibrations in the out-of-plane direction as well as in the in-plane direction of the damping wall.
Here, it is preferable to use a polymer compound such as a polymer, acrylic, silicon, urethane, and diene as the viscoelastic body. Strictly speaking, a viscoelastic body is understood as frequency dependence, and is distinguished from speed dependence. However, in the present invention, if it is frequency dependence in a broad sense, it is speed dependence. The viscoelastic body is made speed dependent.

  The invention according to claim 4 is the vibration control wall according to any one of claims 1 to 3, wherein the limiting mechanism is formed by friction-joining a plurality of steel plates in contact with each other. It is characterized by that.

  Such a vibration control wall restricts input exceeding the capacity of the viscoelastic body and the wall part by a restriction mechanism having a simple structure. As a configuration of the limiting mechanism, for example, a plurality of steel plates having long holes in contact with each other may be friction-joined by screwing nuts to bolts penetrating the long holes.

  In addition, if the light-transmitting material of the damping wall is glass or polycarbonate, polyethylene terephthalate, or acrylic plastic, it has a predetermined strength, excellent light transmission, and excellent aesthetics. It is possible to construct a seismic control structure.

In addition, by constructing the wall body portion with blocks made of a plurality of light-transmitting materials laminated via joint materials, it is possible to construct a vibration-damping wall having excellent daylighting and design properties.
Furthermore, if these blocks adjacent in the horizontal direction are stacked with a step, it is possible to make the wall portion a more integrated face material, which is preferable. In other words, when the horizontal joint passes linearly, the joint may shear by the horizontal force, so by shifting the adjacent blocks by, for example, half of the block height, the horizontal joint is formed in an uneven shape, An integrally structured wall body with a high load resistance capable of preventing shear deviation is constructed.

  ADVANTAGE OF THE INVENTION According to this invention, while the response of a building is attenuate | damped and a wide view is ensured, it can provide the damping wall excellent in daylighting property and aesthetics.

Preferred embodiments of the present invention will be described with reference to the drawings. In the description, the same reference numerals are used for the same elements, and duplicate descriptions are omitted.

<First Embodiment>
1st Embodiment describes the case where the damping wall 1 is installed between the ceiling slab 3 and the floor slab 4 of an installation floor, as shown in FIG.

  As shown in FIG. 1, the damping wall 1 has a damping mechanism 20 that reduces the response of the building due to disturbances such as earthquakes and winds, a limiting mechanism 30 that limits the magnitude of input, and a damping capability of the damping mechanism 20. A wall body portion 10 having appropriate strength and rigidity is provided. The wall 10 is composed of two glass plates 11 (see FIG. 2) that are light transmissive materials, and the left and right sides thereof are fixed by a vertical frame 13. In addition, the number of the glass plates 11 which comprise the wall part 10 is not limited.

As shown in FIG. 2, the damping mechanism 20 is installed between the ceiling slab 3 and the wall 10 on the installation floor, and includes an attenuation upper member 22 and an attenuation lower member 23. A viscoelastic body 21 is interposed in the gap between them, and the steel plate and the viscoelastic body 21 constituting the attenuation upper member 22 and the attenuation lower member 23 are laminated so as to be horizontal.
The limiting mechanism 30 is installed between the floor slab 4 on the installation floor and below the wall body portion 10, and includes a limiting upper member 32 and a limiting lower member 33, and these limiting upper members 32. The joint portion of the restriction lower member 33 is friction-joined via the friction surface 31.

  Hereinafter, the detail of the damping wall 1 of 1st Embodiment is demonstrated.

  As shown in FIG. 2, the damping upper member 22 of the damping mechanism 20 is made of a steel material having a substantially U-shaped cross section formed by two horizontal members and one vertical member. The upper surface is fixed to the lower surface of the ceiling slab 3 with a filler 24 having a sufficient adhesive force with respect to the input so that the opening of the cross section faces either the front or the rear of the damping wall 1. Here, the method of fixing the attenuation upper member 22 to the ceiling slab 3 is not limited. For example, the attenuation upper member 22 may be fixed via a fixing member made of an anchor or the like embedded in the ceiling slab 3.

  As shown in FIG. 2, the damping lower member 23 is a steel member formed in a substantially U-shaped section having the same shape as that of the damping upper member 22 and oriented in the direction opposite to the damping upper member 22.

  The attenuation upper member 22 and the attenuation lower member 23 are engaged with each other such that one horizontal member is sandwiched between the horizontal members. And the meshing part of the horizontal member of the attenuation | damping upper member 22 and the horizontal member of the attenuation | damping lower member 23 is joined by interposing the viscoelastic body 21. FIG.

The viscoelastic body 21 is interleaved with the steel plate which is the horizontal member of the attenuation upper member 22 and the attenuation lower member 23 by being interposed in the meshing portion of the horizontal member of the attenuation upper member 22 and the horizontal member of the attenuation lower member 23. Three layers are stacked so as to be horizontal in the vertical direction. In addition, although the installation method between the attenuation | damping upper member 22 and the attenuation | damping lower member 23 of the viscoelastic body 21 is not limited, In 1st Embodiment, the viscoelastic body 21 of the state which has fluidity | liquidity is used. This is performed by pouring into the gap between the attenuation upper member 22 and the attenuation lower member 23 and then solidifying.
Here, the viscoelastic body 21 uses a polymer having a speed-dependent property, such as a polymer compound such as acrylic, silicon, urethane, and diene, and absorbs a dynamic force acting on the building. As long as the viscoelastic body 21 is not damaged, it is preferable that the thickness thereof is smaller than the installation area because the damping property is more excellent.

  As shown in FIG. 2, the restriction upper member 32 of the restriction mechanism 30 is fixed so that the upper surface thereof is fixed to the lower surface of the wall portion 10 and the lower surface of the horizontal member protrudes downward. It consists of two vertical members. The lower limit member 33 has a lower surface fixed to the upper surface of the floor slab 4 via a filler 34, and two vertical members fixed to the upper surface of the horizontal member so as to protrude upward. It is comprised from the member.

  The vertical member of the restricting lower member 33 is disposed so as to abut on the inner side of the vertical member of the restricting upper member 32 (friction surface 31). Long holes 35 are respectively formed in the vertical members of the restriction upper member 32 and the restriction lower member 33, and the joining of the restriction upper member 32 and the restriction lower member 33 is performed with a bolt inserted into the long hole 35. This is done by fastening the nut BN. That is, the upper limit member 32 and the lower limit member 33 are joined by the frictional force of the friction surface 31 generated by the axial force of the bolt and nut BN. The long hole 35 is an oval bolt hole formed so that its long side is in the horizontal direction. When a horizontal force about the maximum strength of the viscoelastic body 21 is applied, the long hole 35 is restricted with the restriction upper member 32. Slip occurs on the friction surface 31 with the lower member 33, and excessive input is suppressed. In the first embodiment, as shown in FIG. 1, four long holes 35 are formed in the left-right direction of the damping wall 1 with a predetermined interval. A washer W is interposed between the installation surfaces of the bolt, the nut BN, and the restricted upper member 32.

A glass plate fastening means 15 is integrally formed before and after the damping lower member 23 of the damping mechanism 20, and the upper end of the glass plate 11 is clamped by the glass plate fastening means 15 via bolts and nuts BN. It is fixed. A horizontal frame 14 is formed on the upper surface of the restriction mechanism 30 and fixes the lower end of the glass plate 11.
Here, the joining method of the damping mechanism 20 and the limiting mechanism 30 and the wall portion 10 is not limited to the above-described method, and may be appropriately selected from known means.

  The damping wall 1 according to the first embodiment has the effect of absorbing and damping the horizontal force during an earthquake or strong wind by the damping force of the viscoelastic body 21 of the damping mechanism 20. In the first embodiment, the required damping force is ensured by laminating three layers of viscoelastic bodies 21 corresponding to the size of the assumed disturbance and the area that can be secured under the ceiling slab 3. ing.

  Moreover, according to 1st Embodiment, since the glass plate 11 occupies most of the damping wall 1, the damping structure excellent in daylighting property and aesthetics can be provided. Moreover, since the installation location of the damping wall 1 is not limited, the variation of an application location can be expanded.

  Further, the damping wall 1 functions as a partition by being fixed integrally to the ceiling slab 3 and the floor slab 4 on the installation floor and bearing the force acting on the building according to the strength and rigidity of both slabs. A function of reducing the response of the building as a vibration control wall can be added to the conventional partition wall that has only been provided, and a better building structure can be constructed. Furthermore, if the damping wall is fixed to the upper and lower slabs projecting from the beam member as a so-called cantis slab, the beam member is not exposed to the exterior of the building and is made of a glass block. Since the area of the outer wall surface is widened, it is possible to construct a building having excellent daylighting, openness and aesthetics as well as excellent vibration control.

Since the damping wall 1 slips on the friction surface 31 of the limiting mechanism 30 to prevent excessive input, the wall portion 10 (glass plate 11) and the damping mechanism are not damaged. The limiting mechanism 30 has a simple configuration in which the bolts and the nuts BN are fastened with a predetermined torque using the long holes 35 formed in the plurality of steel plates. It can be easily managed and has excellent workability. In addition, the sliding load can be easily controlled by sandwiching a sliding material having a constant friction coefficient such as Teflon (registered trademark) on the friction surface 31.
In the restriction mechanism 30, the restriction upper member 32 and the restriction lower member 33 are joined via a bolt and a nut BN inserted through the elongated hole 35, so that a horizontal force exceeding the strength of the viscoelastic body 21 is applied. In this case, the viscoelastic body 21 and the wall body portion 10 (glass plate 11) are prevented from being damaged by the restriction mechanism 30 being displaced on the friction surface 31 by the length of the long hole 35.

  Further, when the horizontal force is equal to or less than the strength of the viscoelastic body 21, the frictional force of the friction surface 31 prevents the displacement of the limiting mechanism 30 and does not hinder the damping effect of the viscoelastic body 21. That is, the damping wall 1 has a horizontal force input limiting function by the friction surface 31 and the long hole 35.

  Moreover, since the viscoelastic body 21 is laminated | stacked so that it may become horizontal, there exists a damping effect with respect not only to the in-plane direction of the damping wall 1 but to the horizontal force of an out-of-plane direction.

In the second embodiment, the glass block 11 ′ is laminated. The upper end of the fixed rod (not shown) to be used is fixed to the lower end of the damping mechanism 20, and the lower end of the fixed rod is fixed to the upper end of the limiting mechanism 30.

  According to the second embodiment, since the vibration control wall 1 ′ can be constructed using the glass block 11 ′, it is possible to construct a building that is excellent in daylighting and aesthetics as well as excellent vibration control. In addition, the installation location of the damping wall 1 'is not limited to the inner surface of the beam column structure, and it can be installed between the slabs on the upper and lower floors if it has sufficient strength and rigidity to meet the damping performance. It is possible to design freely without any restrictions. Moreover, since each glass block 11 'itself is lightweight, it can be easily constructed manually.

Further, if the damping wall 1 ′ is fixed as an outer wall to the upper and lower slabs projecting from the beam member like a cantis slab, the beam member is not exposed to the exterior of the building, and lighting can be obtained. Since the area of the outer wall surface increases, it is possible to construct a building that is bright, open, and beautiful with excellent vibration control.

  In the above, the example of preferred embodiment was demonstrated about this invention. However, the present invention is not limited to the above-described embodiment, and the above-described constituent elements can be appropriately changed without departing from the spirit of the present invention. For example, the damping wall shown in each of the above embodiments can be installed regardless of whether it is a new building or an existing building, and can also be used for damping control of an existing building.

  In each of the above embodiments, the damping mechanism is disposed on the upper surface (below the beam member or the ceiling slab) of the wall body, and the limiting mechanism is disposed on the lower surface of the wall body (on the floor slab). The location where the limiting mechanism is installed is not limited, and the configuration shown in each of the above embodiments may be rotated 180 ° so that the limiting mechanism is disposed on the upper surface of the wall portion and the damping mechanism is disposed on the lower surface. . In this case, it is preferable to suspend the wall body from the upper floor housing so that the weight of the wall body portion is not loaded on the viscoelastic body of the damping mechanism.

  In addition to increasing the strength of the material itself as in tempered glass, by providing a thin film member or plate-like member that does not impair translucency on at least one surface of the glass block or glass plate, Cracks can be dispersed to prevent brittle fracture.

Moreover, there is no restriction | limiting regarding the shape and dimension of the member which comprises a beam pillar frame, a ceiling slab, and a floor slab, the shape of a light transmissive material, a dimension, a material, etc.
Further, it goes without saying that each member of the damping mechanism and the limiting mechanism is not limited to a steel material as long as it has a sufficient proof strength against an assumed external force. Further, the shape of each member, the combination thereof, and the like are not limited.

Further, although the viscoelastic body is used, the damping material interposed in the joint portion between the upper member and the lower member is not limited, and other speed-dependent materials may be used.
Moreover, although the structure which deform | transforms via a friction surface and restrict | limits an input was employ | adopted as a restriction | limiting mechanism, for example, it is good also as a structure which provides a deformation | transformation restriction | limiting mechanism in an attenuation | damping part and restrains a deformation | transformation.

  In addition, as a damping mechanism, the viscoelastic body is configured to be laminated in a horizontal direction with a plurality of layers through the steel plate, but the number of layers of the viscoelastic body is not limited, and the viscoelastic body installation area And may be set as appropriate according to the response of the assumed building.

Moreover, in 2nd Embodiment, if a wall body part is formed by attaching a glass block to the block attachment frame formed previously, the effort of construction will be saved and construction period can be shortened.
Moreover, it goes without saying that the degree of freedom in design may be expanded by using a transparent or translucent material having daylighting properties as the joint material of the wall portion in the second embodiment.

  Moreover, in the said 2nd Embodiment, it was assumed that the damping wall was installed in the construction surface of the beam column structure. For example, when the upper and lower slabs have sufficient strength against the damping performance, The damping wall may be fixed between the upper and lower slabs, and it does not matter where the damping wall is installed.

  Further, in the second embodiment, the four rounds of the damping wall are fixed to the inner surface of the beam column frame. However, it is only necessary to fix at least the upper and lower housings so that horizontal force can be transmitted.
