  In the vibration control structure disclosed in Patent Document 1, the deformation of the vibration control material is large and higher vibration control performance can be obtained as compared with the joint damper or the like, but the size of the vibration control material is relatively small. Because of its small size, the range of viscoelastic properties such as loss tangent (tan δ), storage elastic modulus (E ′) and deformation capacity is limited to achieve insufficient seismic performance. There is also a problem that. In addition, since the diagonal point connecting member generates a bending force on the shaft member, there is a problem that a sufficient displacement cannot be applied to the damping material.

  The first and second attachment portions 15 and 16 have a flat plate-like portion 17 of an isosceles trapezoidal plate that forms the attachment portion main body, and a hypotenuse that is an open side edge of the flat plate-like portion 17 has an L-shaped cross section of about 30 mm. A flange 17 b that is bent and extends in the normal direction is formed, and has a mounting member 18 provided along the lower bottom portion of the flat plate-like portion 17, and is fixed to the column 21 via the mounting member 18. Has been.

  The flat plate portion 17 is made of a material having rigidity such as a metal material, a ceramic material, a plastic material, a wood material, a volcanic glassy multilayer material, and the like. For example, the upper bottom 30 to 400 mm, the lower bottom 500 to 2500 mm, and the upper The length from the bottom to the bottom is 150 to 450 mm.

  The mounting member 18 is composed of an L-shaped member having the same length as the length of the lower bottom portion, for example, by a material having rigidity such as a metal material, a ceramic material, a plastic material, a wood material, and a volcanic glassy multilayer material. Has been. The mounting member 18 is a column in which one surface material portion having an L-shaped cross section abuts along the lower bottom portion of the flat plate portion 17 and the other surface material portion extends in a direction perpendicular to the one surface material portion. 21 is provided so as to be in surface contact. Thereby, each of the first and second attachment portions 15 and 16 is formed such that the tip thereof is bent into an L-shaped cross section, and the bent portion is mounted and fixed in surface contact with the column 21. Yes. Note that the fixing of the first and second mounting portions 15 and 16 to the column 21 of the mounting member 18 is performed by, for example, bonding with an epoxy-based adhesive or a urethane-based adhesive, such as a nail, a screw, or a lag screw. It is performed by hitting with a fixing tool or a combination thereof.

  Each of the first and second attachment portions 15, 16 has a plurality of elongated holes 17 a extending in the horizontal direction at the bottom of the flat plate portion 17 at intervals in the vertical direction. Bolt holes are provided correspondingly to one of the face member portions of the mounting member 18 that abuts, and the bolt 19 is passed from one side to the long hole 17a and the bolt hole, and the head portion is The attachment member 18 is integrally provided on the flat plate portion 17 by being engaged and fastened together on the other side. Here, by adjusting the position through which the bolt 19 of the long hole 17a of the flat plate portion 17 is passed, the first mounting portion 15 is moved sideways, that is, in the arrangement direction of the first and second mounting portions 15, 16. It can be expanded and contracted. The second mounting portion 16 has the same configuration, and the second mounting portion 16 can be expanded and contracted laterally, that is, in the direction in which the first and second mounting portions 15 and 16 are disposed.

  Each of the damping material 14 and the second damping material 32 is, for example, a silicon-based viscoelastic body, a diene-based viscoelastic body, an isoprene rubber (IR) viscoelastic body, natural rubber (NR), or styrene-butadiene rubber ( SBR), butadiene rubber (BR), isoprene rubber (IR), nitrile rubber (NBR), chloroprene rubber (CR), etc. It is formed in a rectangular flat plate shape having a length of 30 to 400 mm, a width of 30 to 400 mm, and a thickness of 1 to 50 mm. The outer shape is not limited to a rectangular flat plate shape, and is appropriately selected according to the shapes of the first, second, and third displacement plates 11, 12, 13, and the like.

The viscoelastic material forming each of the damping material 14 and the second damping material 32 is preferably in a frequency range of 0.1 to 10 Hz as a dynamic viscoelastic property in a temperature range of 5 to 30 ° C. The loss tangent is 0.4 or more and the storage elastic modulus is 1 × 10 ⁵ Pa or more.

  Each of the damping material 14 and the second damping material 32 is sandwiched between the first and second displacement plates 11 and 12 or the mutually opposing portions of the second and third displacement plates 12 and 13. For example, the first and second displacement plates 11 and 12 or the second and third displacement plates 12 and 13 are, for example, an epoxy-based adhesive or a urethane-based adhesive. Or vulcanized.

  Other configurations are the same as those of the first embodiment.

  According to the above configuration, in addition to the first and second displacement plates 11 and 12 and the damping material 14, the third displacement plate 13 provided to face the second displacement plate 12 and the second and third displacement plates. And a second damping member 32 provided between the displacement plates 12 and 13, and the third displacement plate 13 is one of the pair of pillars 21 by the first attachment portion 15, similarly to the first displacement plate 11. In addition, since the oblique side portion, which is the open side edge of the flat plate portion 17 of each of the first and second mounting portions, is constituted by the flange 17b extending in the normal direction, the flat plate portion 17 is difficult to bend and distortion in the normal direction is reduced, whereby the reaction force when the damping material 14 and the second damping material 32 are deformed can be efficiently transmitted to the column 21. . Further, instead of the flange 17b formed by bending the oblique side portion, which is the open side edge of the flat plate portion 17, into an L-shaped cross section, a flange having an L-shaped angle welded to the open side edge of the flat plate portion 17 may be provided. Similar effects can be obtained.

  In addition, since the first and second mounting portions 15 and 16 are configured to be extendable and contractable in the direction in which they are arranged, even if the inter-column spacing of the plurality of columns 21 is various, they can be accommodated, and a single type The panel-like vibration damper 10 can be unified.

  Furthermore, the damping material 14 has a shorter length in the longitudinal direction than any of the first and second mounting portions 15, 16, and the damping material 14 is in any of the first and second mounting portions 15, 16. However, since it is arranged so as to correspond to the middle portion in the vertical direction, the reaction force when the damping material 14 is deformed can be efficiently transmitted to the column 21, and the first and second displacement plates 11, 12 is reduced, and it is possible to avoid breakage of the joint portion between the first and second attachment portions 15 and 16 and the column 21.

  Other functions and effects are the same as those of the first embodiment.
