Description

  The present invention relates to a damping wall structure that can be vertically displaced in a building, which can be applied to a non-bearing wall of a building such as a curtain wall by allowing it to be displaced up and down.

  Conventional damping wall structures applied to building walls include hysteresis dampers (displacement-dependent dampers) such as friction dampers and steel dampers, speed-dependent dampers such as oil dampers, viscous dampers, and viscoelastic dampers. Various damping wall structures used are known. In addition, composite damper structures combining these different types of dampers are also known, and various types of dampers such as shear link type, toggle type, brace type, stud type, wall type, step column type are also available as installation types. A structure has been proposed.

  For example, as applied to a wooden building, Patent Literature 1 discloses a wooden building vibration control device 1 applied to a wall portion of a wooden frame structure, which includes a column, a base BS, and a beam BM. Energy absorption composed of a wooden frame member 5, a wooden wall member 4 attached to the frame member 5, and a viscoelastic body 8 sandwiched between two metal plates 9A and 9B. Material 7. In the present invention, a plurality of energy absorbing members 7 are arranged side by side between the frame member 5 and the wooden wall surface member 4, and the metal plates 9 A and 9 B of the energy absorbing member 7 are bonded to the frame member 5 and the wooden wall member 4. The vibration damping device 1 for a wooden building is disclosed in which the vibration energy is absorbed by the viscoelastic body 8 of the energy absorbing material 7 (Claim 1, Specification of Claims of Patent Document 1) (See paragraphs [0011] to [0018] of FIGS. 5 and 6).

  However, the wooden building vibration control device 1 described in Patent Document 1 is applied to a load-bearing wall, and the wall surface material 4 must be a structural plywood, a structural panel, etc. Could not be adopted. This imposes design design restrictions that make it difficult to use large daylighting windows, and the damping damper cannot be applied to all walls of the building. There was a problem that the wall incorporating the damping device was not long enough, and as a result, the damping function was insufficient.

  In addition, as applied to an RC building, Patent Document 2 discloses a damping mechanism 20 that reduces the response of a building due to a disturbance such as an earthquake or wind, a limiting mechanism 30 that limits the size of an input, and an attenuation. The damping wall 1 includes a wall portion 10 made of a glass plate 11 having strength and rigidity corresponding to the damping performance of the mechanism 20, and the damping mechanism 20 is a lower surface of the ceiling slab 3. And the upper surface of the wall body portion 10, the limiting mechanism 30 is disclosed as the damping wall 1 installed between the upper surface of the floor slab 4 and the lower surface of the wall body portion 10 (Patent Document 2). (See claims 1 to 3 in the claims, paragraphs [0019] to [0028] of the specification, FIGS. 1 and 2 of the drawings, etc.)

  However, even if the damping wall 1 described in Patent Document 2 can be countered by the damping mechanism 20 and the limiting mechanism 30 against the horizontal force, the wall surface is a structural material on which the seismic force or the like directly acts. Since the glass plate 11 or the like which is a face material is fitted in the glass plate, the glass plate 11 or the like which is the face material is required to have a considerable strength and rigidity, and must be expensive. When the bending stress is applied to the ceiling slab 3 or the floor slab 4, there is a problem that the glass plate 11 or the like may be damaged.

  DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment for carrying out a building damping wall structure according to the present invention will be described in detail with reference to the drawings.

[First Embodiment]
First, using FIG. 1 to FIG. 7, the damping wall structure of a building according to the first embodiment of the present invention will be described by exemplifying a case where it is applied to an outer wall of an RC building X having a ramen structure. .

  As shown in FIG. 1, the damping wall structure 1 which is the damping wall structure of the building which concerns on 1st Embodiment is between the floor slabs which protrude outside from the ramen (frame) which is the structural frame of the building X. The damper structure applied when attaching the plate glass 2 which is a face material as a curtain wall which is a non-bearing wall is illustrated, and is applied to the upper support structure of the plate glass 2 in this embodiment. Of course, in the illustrated embodiment, the upper and lower sides are reversed and the present invention can be applied to the lower support structure of the plate glass 2.

  As shown in FIG. 2, the damping wall structure 1 includes a plate glass 2 that is a face material, a first plate 3 bonded to the plate glass 2, a second plate 4 bonded to the first plate 3, It is comprised from the support angle 5 which is the structural housing joined to this 2nd plate, the damping damper 6 etc. which suppress the vibration of the building X, etc.

(Plate glass)
The plate glass 2 according to the first embodiment is made of a general float glass manufactured by a float manufacturing method containing silicate as a main component, and as shown in FIG. It has a rectangular shape (rectangular shape) and has an upper side portion 21, a left side portion 22, and a right side portion 23. Of course, the plate glass 2 is not limited to the float glass, and may be a plate-like glass made of another material such as a mesh glass, a tempered glass, a heat ray reflective glass, or an organic glass such as a polycarbonate or an acrylic resin. Good. That is, the plate glass 2 may be a transparent or translucent face material having a predetermined rigidity that functions as a window. Further, when not used as a window, neither light transmittance nor water resistance is required. In short, if the plate glass 2 is a surface material which comprises the wall surface of the building X, it will not be specifically limited.

  As shown in FIGS. 2 and 3, the glass plate 2 has an upper side 21 bonded to the first plate 3 with an adhesive B, and the first plate 3 is bolted to the second plate 4 with bolts and nuts BN. The second plate 4 is supported by the structural housing via the first plate 3 and the second plate 4 by being bolted to the support angle 5 which is the structural housing by a bolt and a nut BN.

  The adhesive material B may be appropriately selected depending on the face material and the material of the plate. However, when glass and a metal plate such as stainless steel are bonded, it is suitable for bonding different materials having a large difference in linear expansion coefficient. Therefore, an elastic adhesive made of a silicone resin such as a silicone sealant is preferable.

(First plate)
As shown in FIGS. 2 and 3, the first plate 3 is a pair of front and back steel plates of the same shape bonded so as to sandwich the upper side portion 21 along the upper side portion 21 of the plate glass 2. It has a function of sandwiching the portion 21. The first plate 3 according to the present embodiment is a rust-proof coated steel plate, but in consideration of corrosion resistance, a stainless steel plate is preferable, and a corrosion-resistant steel plate subjected to hot dip galvanization, electroplating, or aluminum zinc alloy plating is adopted. You can also However, the material of the first plate 3 is not particularly limited, and may be another metal plate such as an aluminum alloy or a resin plate such as polycarbonate. In short, the first plate 3 may be a plate-like member having predetermined durability and rigidity that can support the plate glass 2.

  Further, as shown in FIG. 4, the first plate 3 has a horizontally long rectangular shape (rectangular shape) in an elevational view in which the horizontal direction is the longitudinal direction. A pair of left and right intervention holes 31 and 32 for joining the second plate 4 via the attachment structure 7 are formed. Further, the glass plate 2 is bonded to the lower portion of the first plate 3 as described above. The intervention holes 31 and 32 according to the present embodiment are circular holes, but may be through holes having a shape corresponding to the shape of the intervention structure 7 to be interposed.

  Moreover, although the 1st plate 3 illustrated what consists of two plates of a pair of front and back, what consists of one plate can also be substituted. However, from the viewpoint of sandwiching the second plate 4 with an interposition structure 7 described later, the first plate 3 is preferably composed of a pair of front and back two plates.

(Second plate)
2 and 3, the second plate 4 is a plate made of a stainless steel plate interposed between the pair of first plates 3 and 3 along the upper side portion 21 of the plate glass 2. By being supported by the structural housing, it has a function of indirectly supporting the first plate 3 and the plate glass 2. The material of the second plate 4 is not particularly limited, as with the first plate 3, and may be another metal plate such as a corrosion-resistant steel plate or aluminum alloy, or a resin plate such as polycarbonate. However, as will be described in detail later, the material of the second plate 4 is preferably a material having a high coefficient of friction with the interposition structure 7.

  Further, as shown in FIG. 5, the second plate 4 has a horizontally long rectangular shape (rectangular shape) in the elevational view with the horizontal direction as the longitudinal direction, and the first plate is disposed below the second plate 4. 3, long holes 41 and 42 are formed to be horizontally displaceable (that is, relatively slidable (slidable) in the horizontal direction (lateral direction)). Long holes 43, 44, and 45 are formed for connection to be freely displaceable (that is, freely slidable (slidable) in the vertical direction).

  As shown in FIG. 6, the long holes 41, 42, 43, 44, 45 are long grooves 41 ′, 42 ′, 43 ′, 44 ′, 45 ′ with one end of the hole reaching the end of the second plate 4. As shown in FIG. 7, the long grooves 41 ′ and 42 ′ are completely divided into two plates by connecting both grooves, and long grooves 41 ″ and 42 connected by separate members. "It does not matter. Even with such long grooves 41 ′, 42 ′, 43 ′, 44 ′, 45 ′ or long grooves 41 ″, 42 ″, functions equivalent to those of the long holes 41, 42, 43, 44, 45 described above are achieved. It is clear that it can be demonstrated. In short, the first plate 3 and the second plate 4 are connected so as to be horizontally displaced, and the second plate 4 and the support angle 5 may be connected so as to be vertically displaced.

(Support angle)
The support angle 5 is an L-shaped angle made of angle steel attached along the floor slab on the upper floor of the building X, and is bolted by the second plate 4, bolts and nuts BN, and the second plate 4 and the second plate 4. 2 is a structural frame that supports the plate glass 2 and the like indirectly connected and supported by the two plates 4. The support angle 5 according to the present embodiment is made of a steel material to which rust prevention coating has been applied, but may be stainless steel, or may be an L-shaped angle made of another metal such as a corrosion-resistant steel plate or an aluminum alloy. I do not care.

  Further, the support angle 5 may be a plate embedded in an upper floor slab that is a structural frame of the building X, or the second plate 4 is joined directly with a anchor bolt from a step of the beam or floor slab. It may be in the form of supporting. In short, any structural housing that can support the second plate 4 or the plate glass 2 may be used.

(Vibration damper)
Next, the vibration damper 6 will be described with reference to FIGS. The vibration damper 6 mainly includes a pair of front and back first plates 3 sandwiching the plate glass 2, a second plate 4 interposed between the pair of first plates 3, and each insertion hole of the first plate 3. It is composed of four interposing structures 7 interposed between the front and back surfaces 31 and 32 and a disc spring 8 that presses the interposing structures 7 with the restoring force of an elastic body. The vibration damper 6 has an interposition structure by tightening a pair of front and back intervening structures 7 and the first plate 3 via a rectangular square washer W1 and a disc spring 8 with bolts and nuts BN as fastening members. The second plate 4 is sandwiched between the bodies 7, and the first plate 3 and the second plate 4 are prevented from being relatively horizontally displaced along the long holes 41 and 42 by the frictional force, and the building This is a so-called friction damper that reduces the horizontal vibration of X.

  Of course, the vibration damper 6 may be another hysteresis damper (displacement-dependent damper) such as a steel damper, or a speed-dependent damper such as an oil damper, a viscous damper, or a viscoelastic damper. In short, any damper that can suppress relative horizontal displacement of the first plate 3 and the second plate 4 along the long holes 41 and 42 may be used.

(Intervention structure)
As shown in FIG. 2, the intervening structure 7 is a donut-shaped aluminum ring made of an aluminum plate thicker than the thickness of the first plate 3, and the intervening structure 7 has a thickness different from that of the first plate 3. The mechanism always contacts and slides on the second plate 4, and the restoring force of the disc spring 8 is directly connected to the frictional force between the interposition structure 7 and the second plate 4. The intervening structure 7 may be a metal plate other than an aluminum plate such as a steel plate, a stainless steel plate, or a brass plate, or a resin (resin) such as rubber.

  In short, in the vibration damper 6 according to the present embodiment, a frictional force is generated between the second plate 4 made of stainless steel and the second plate 4 made of aluminum, so that the stainless steel plate and the aluminum plate High frictional force (particularly dynamic frictional force) is generated by the combination of Therefore, the composition of the material of the second plate 4 and the interposition structure 7 may be reversed, not a combination of a stainless steel plate and an aluminum plate, but a combination of dissimilar metal plates that increase the coefficient of dynamic friction. It doesn't matter.

  Of course, the combination of the material of the second plate 4 and the interposition structure 7 is not limited to the combination of different kinds of metal plates, the combination of the same type of metal plates, the combination of the metal plate and a resin (resin) plate such as rubber, A combination of resins can also be substituted. In short, any combination may be used as long as the coefficient of dynamic friction continuously increases during sliding.

  However, a combination of dissimilar metal plates is preferable because it has high durability such as wear resistance, can withstand repeated use, and is excellent in corrosion resistance and weather resistance. Particularly, since the combination of stainless steel and aluminum has a high dynamic friction coefficient, vibration energy can be efficiently consumed and absorbed as heat energy of friction.

(Connection mechanism between second plate and support angle)
Next, a connection mechanism between the second plate 4 and the support angle 5 will be described with reference to FIGS. The second plate 4 and the support angle 5 are connected via a donut-shaped round washer W2 by bolts and nuts BN inserted into the long holes 43, 44, 45. Further, a cylindrical tube 9 is fitted to the bolt and nut BN, and the length of the tube 9 is longer than the length obtained by adding the thickness of the second plate 4 and the support angle 5. Is set. For this reason, the second plate 4 connected to the support angle 5 which is a structural housing can be displaced up and down along the long holes 43, 44 and 45.

  According to the damping wall structure 1 according to the first embodiment described above, the connection between the second plate 4 and the support angle 5 is freely movable up and down along the long holes 43, 44, 45. The plate glass 2 supported by the support angle 5 via the second plate 4 is not directly subjected to a seismic force, a horizontal force due to a wind load, or a large vertical force. For this reason, a damping wall structure is applicable also to a non-bearing wall. Therefore, by providing a damping wall structure on many wall surfaces of the building, the damping function of the entire building can be improved, and vibrations can always be suppressed from vibration due to wind loads to large earthquakes. Therefore, the durability of the building can also be improved.

  In addition, in the damping wall structure 1 which concerns on 1st Embodiment, although the thing of donut shape and circular shape was illustrated as the interposed structure 7 and the interposed holes 31 and 32, rectangular shape, elliptical shape, long hole shape, etc. Other shapes may be used. In short, any shape can be applied as long as the second plate 4 is sandwiched in the interposition structure 7.

[Second Embodiment]
Next, a building damping wall structure according to a second embodiment of the present invention will be described with reference to FIGS. The damping wall structure 1 ′, which is a damping wall structure of a building according to the second embodiment, is different from the damping wall structure 1 according to the first embodiment described above, with two plate glasses 2. This is a point that is a double-glazed glass, which will be mainly described.

  The damping wall structure 1 ′ includes two plate glasses 2 that are face materials, four first plates 3 bonded to the plate glasses 2, and a second plate 4 ′ bonded to the first plate 3. And a support angle 5 that is a structural frame joined to the second plate 4 ′, a vibration damper 6 ′ that suppresses vibration of the building X, and a space that is interposed above the first plate 3 to fill the space. It is comprised from the plate 10 grade | etc.,.

  As shown in FIGS. 8 and 9, the second plate 4 ′ has substantially the same configuration as the second plate 4 described above. The difference is that the second plate 4 ′ is slightly longer in the vertical direction because it is connected by a bolt and a nut BN. It is a point. The damping damper 6 'has substantially the same configuration as that of the damping damper 6 described above. The difference is that the number of the interposing structures 7 is increased to four, and the frictional force is improved.

(Space plate)
The space plate 10 is substantially the same material as the second plate 4 described above, and the space above the first plate 3 and the first plate 3 is filled by the increase in the first plate 3. Is a plate to prevent bending by tightening bolts and nuts BN. In addition, the code | symbol K in a figure is a buffer material which fills the space between the two glass plates 2. FIG.

  According to the damping wall structure 1 ', the plate glass 2 is a double-layer glass, so not only the vibration of the building is reduced by the vibration damper, but also the heat insulation and sound insulation of the building by the double-layer plate glass. Can also be improved. Further, according to the damping wall structure 1 ′, the frictional force of the damping damper 6 ′ increases due to the increase in the number of interposition structures 7, so that the vibration is absorbed even compared with the damping damper 6. The reduction function is improved.

[Third Embodiment]
Next, a building damping wall structure according to a third embodiment of the present invention will be described with reference to FIGS. The damping wall structure 1 '' which is the damping wall structure of the building according to the third embodiment is different from the damping wall structure 1 according to the first embodiment described above in that the damping damper is a friction damper. This is a point that is a metal damper, which will be mainly described, and the same components are denoted by the same reference numerals and the description thereof is omitted.

  As shown in FIGS. 10 and 11, the damping wall structure 1 ″ includes a plate glass 2 that is a face material, a pair of front and back first plates 3 ″ bonded to the plate glass 2, and the first plate 3 ″. A pair of second plates 4 ″ joined to each other, a structural housing 5 ″ joined to the second plates 4 ″, a damping damper 6 ″ for suppressing the vibration of the building X, and the like.

As shown in FIG. 11, the first plate 3 ″ is a plate made of a steel material having a comb-like projection 30 ″ projecting in the vertical direction, and the second plate 4 ″ is arranged in the vertical direction. The rough shape having the comb-shaped protrusions 40 ″ is a plate made of comb-shaped mild steel or low yield point steel. These comb-shaped protrusions 30 "and 40" are alternately combined to constitute a vibration damper 6 ". Here, the low yield point steel has a low carbon content and usually has a yield point. It refers to a steel material having a strength of 225 N / mm ² or less and extremely high ductility.

  The vibration damper 6 ″ has a first plate 3 ″ and a second plate 4 ″ that are joined in a vertically displaceable manner by alternately combining comb-like protrusions 30 ″ and 40 ″ along the vertical direction. Since the second plate 4 ″ is made of mild steel or low yield point steel, the root of the comb-like protrusion 40 ″ yields at an early stage and can be horizontally displaced.

  Further, since the contact protrusion P rounded at the tip protrudes in the lateral direction (horizontal direction) on the side of the comb protrusion 30 ″ at the tip of the comb protrusion 40 ″, the comb protrusion 40 ″ is formed. Since the distance H that receives the horizontal force Q is constant, the yield bending moment My = Q · H is constant, and the root of the comb-like protrusion 40 ″ yields early and can move within a range of ± δ. Stable yield strength (damper strength) can be obtained. It should be noted that the shape of the contact protrusion P is such that the first plate 3 "and the second plate 4" are at one point of the contact protrusion P regardless of whether the comb-shaped protrusion 40 "is tilted or undulated, such as a pointed tip. Is not particularly limited as long as the distance between the bending moments acting on the root of the comb-like projection 40 ″ of the second plate 4 ″ is constant. The first plate 3 "side of the comb-shaped protrusion 30" may be yielded upside down.

  Unlike the support angle 5 described above, the structural frame 5 ″ is a floor slab or beam on the upper floor of the building X, and the second plate 4 ″ is partially embedded in the structural frame 5 ″. Joined and supported by a structural housing 5 ". Of course, the second plate 4 ″ may be configured to be detachable by interposing a support angle with the structural housing 5 ″. If it is detachable, the second plate 4 ″ can be easily exchanged.

  According to the damping wall structure 1 '', since the damping damper 6 '' is composed of a steel damper made of mild steel or low yield point steel, the yield point of the steel is clear and stable by a simple configuration. Yield strength (damper force) is obtained, and a necessary vibration damping function can be obtained. Also, there is no problem in durability, and maintenance after a large earthquake is simple and easy because only the first plate 3 "and the second plate 4", which are steel materials, are replaced.

  In addition, although the steel plate damper in which the second plate 4 ″ is made of mild steel or low yield point steel is exemplified as the vibration damper 6 ″, the second plate 4 ″ is not limited to soft iron or low yield point steel, but other steel materials. Also, the shape of the second plate 4 ″ is not limited to the comb shape, and a rib is formed in a T shape from the plate, and the side of the rib can be replaced with aluminum, brass, lead, etc. The contact protrusion may be formed in the direction, and the shape is not particularly limited. In short, the second plate 4 ″ and the first plate 3 ″ may be joined so as to be vertically displaceable, and the material of the second plate 4 ″ may be a metal damper that can be easily plastically deformed to absorb vibration energy. Even in such a case, it is clear that the above-mentioned effects can be achieved.

  As mentioned above, although the damping wall structure of the building which concerns on embodiment of this invention was demonstrated in detail, all the embodiment mentioned above or illustrated showed one embodiment actualized in implementing this invention. Therefore, the technical scope of the present invention should not be construed in a limited manner.
