Description

The present invention relates to a vibration control device for buildings and a vibration control structure for buildings using the same, and in particular to a vibration control device that is easy to install and can control the vibration of buildings, and a vibration control structure for buildings using the same.

In recent years, it has become common for cargo transport containers to be used as buildings such as warehouses, stores, and residences.
When using containers as buildings, all that is required is to place them in the desired location and make improvements to suit the purpose. Not only is this less costly than building a new building, but all that is needed is a place to store the containers, making it possible to make effective use of vacant space such as under railway tracks.

Utility Model Registration No. 3193710

However, if a container house is installed under an elevated railway track, it may be subject to traffic vibrations.
A vibration damper such as that described in Patent Document 1 is known for use in wooden houses.
However, the vibration damper in Patent Document 1 is intended to be installed in the framework of an ordinary house and cannot be applied to a container house.

The present invention aims to provide a vibration control device that can control vibrations in buildings such as container houses, and a vibration control structure for buildings that uses the device.

The vibration control device of the present invention, which has been made to achieve the above-mentioned object, includes a fixing member fixed to a concrete foundation under a building, and a building fixing member fixed to the structure of the building, wherein the fixing member has a foundation fixing plate fixed to the upper surface of the concrete foundation, and a front plate erected from the foundation fixing plate approximately parallel to the surface of the structure, and the building fixing member has a back plate arranged approximately parallel to the surface of the structure, two erect portions erected from both ends in the width direction of the back plate toward the surface direction of the structure, and a building fixing portion bent and erected from the end edges of the erect portions toward the outside in the width direction of the structure and abutting against the surface of the structure, and an intermediate plate abuts against the back side of the front plate of the fixing member, and the intermediate plate and the back plate of the building fixing member are bonded via a viscoelastic material.
The fixing member may have an opening for a rear bolt, the intermediate plate may have a rear intermediate bolt hole which is a long hole, and the building fixing member may have a rear bolt hole, and a rear nut may be screwed onto a rear bolt inserted into the rear bolt opening, the rear intermediate bolt hole, and the rear bolt hole to determine the distance between the intermediate plate and the building fixing member.
In addition, the vibration control device of the present invention includes a fixing member that is fixed to a concrete foundation under a building, and a building fixing member that is fixed to the main body of the building, the fixing member having a foundation fixing plate that is fixed to the upper surface of the concrete foundation, and a front plate that stands upright relative to the foundation fixing plate and approximately parallel to the surface of the main body, the building fixing member being flat, and an intermediate plate is abutted against the back surface of the front plate of the fixing member, and the intermediate plate and the building fixing member are bonded via a viscoelastic material.
The fixing member may have a front bolt hole which is a long hole, and the intermediate plate may have an intermediate bolt hole which is a long hole, and one of the front bolt hole and the intermediate bolt hole may be a horizontal long hole and the other may be a vertical long hole.
The fixing member and the intermediate plate may be integrated by screwing nuts onto bolts inserted through the front bolt holes and the intermediate bolt holes .
The fixing member may be formed by dividing the foundation fixing plate and the front plate, the front plate having side walls extending substantially perpendicularly from both sides toward the foundation fixing plate, the foundation fixing plate having side plates extending from both sides, the front plate being capable of fitting between both side walls of the foundation fixing plate, the side walls having side wall bolt holes, the side plates having side plate bolt holes, and a bottom nut being screwed onto a bottom bolt inserted into the side wall bolt hole and the side plate bolt hole, to form the foundation fixing plate and the front plate into one piece.

In addition, the vibration-damping structure of a building of the present invention, which has been made to achieve the above-mentioned objective, has a lower vibration-damping member arranged between the upper surface of the concrete foundation and the bottom plate of the structure, and an upper vibration-damping member arranged between the upper part of the bottom plate of the structure and an anchor plate inserted into an anchor bolt erected from the concrete foundation .
The lower vibration damping member may be surrounded by a protective material.

The present invention provides at least one of the following effects by solving the above-mentioned problems.
(1) The viscoelastic body deforms and, together with the vibration-damping member, can dampen the vibrations of the building.
(2) The front bolt hole and the intermediate bolt hole are a combination of a vertical long hole and a horizontal long hole. Therefore, by adjusting the position of the bolt within the front bolt hole and the intermediate bolt hole, the fixing member can be fixed to the top surface of the concrete foundation in an inclined state.
(3) Since the building fixing member has an upright portion, the intermediate plate and the fixing member can be positioned in a position where they do not interfere with the diaphragm of a container house, for example.

In this description, expressions relating to directions such as front-back, length-width, top-bottom, etc. are defined with respect to the pillars of the building as the reference point, with the front meaning the direction perpendicular to the surface of the pillar, the length-width meaning the height direction of the pillar, and the width-width meaning the direction perpendicular to the front and length-width directions.

[Example 1]
<1> Overview of the Vibration Control Device The vibration control device 1 of the present invention is a component that is arranged and connected to the upper surface of a concrete foundation 2 and the surface of a pillar material 3 of a container house (FIG. 1).
The vibration control device 1 consists of a fixing member 4 fixed to a concrete foundation 2, an intermediate plate 5 provided on the back surface of the fixing member 4, a building fixing member 6 fixed to the surface of the pillar material 3, and a viscoelastic body 7 adhered to both sides of the intermediate plate 5 and the building fixing member 6 (Figure 2).
In this embodiment, the vibration control device 1 is provided on one surface of the rectangular pillar 3 of the container house, but it may be provided on a plurality of surfaces.

<2> Fixing member The fixing member 4 is a steel member that is approximately L-shaped in side view and consists of a foundation fixing plate 41 that is fixed to the upper surface of the concrete foundation 2, and a front plate 42 that stands upright from the rear end of the foundation fixing plate 41 and approximately parallel to the surface of the pillar material 3.
The front plate 42 may have a front opening 422 at a position corresponding to the opening 31 of the pillar material 3 .
The front plate 42 has side walls 43 extending substantially perpendicularly from both sides toward the foundation fixing plate 41. The lower ends of the side walls 43 are fixed to the upper surface of the foundation fixing plate 41 by welding.
The fixing member 4 is fixed to the concrete foundation 2 by post-installed anchors 44 that penetrate the foundation fixing plate 41.

<3> Intermediate Plate The intermediate plate 5 is a steel plate provided on the rear surface of the front plate 42 of the fixed member 4 .
A viscoelastic body 7 is bonded to the rear surface of the intermediate plate 5 .

<4> Arrangement of intermediate plate The intermediate plate 5 is adhered to the building fixing member 6 by a viscoelastic body 7, and is movable in a direction parallel to the back plate 61 of the building fixing member 6 within the elastic range of the viscoelastic body 7.
The intermediate plate 5 has intermediate bolt holes 51 near the upper and lower ends. The intermediate bolt holes 51 are elongated holes in the vertical direction.
Furthermore, the front plate 42 of the fixing member 4 has a front bolt hole 421 at a position corresponding to the intermediate bolt hole 51. The front bolt hole 421 is a horizontally elongated hole.
The intermediate plate 5 is disposed on the rear surface of the front plate 42 of the fixing member 41 by screwing nuts 53 onto bolts 52 inserted through the front bolt holes 421 and the intermediate bolt holes 51 .
The intermediate plate 5 is fixed to the pillar material 3 via the building fixing member 6 and the viscoelastic body 7. On the other hand, the fixing member 4 is fixed to the concrete foundation 2, but if the top surface of the concrete foundation 2 is uneven, it may be tilted at an angle relative to the pillar material 3. In this case, since the front bolt hole 421 and the intermediate bolt hole 51 are a combination of a vertical long hole and a horizontal long hole, the fixing member 4 can be fixed to the top surface of the concrete foundation 2 in an inclined state by loosening the nut 53 and adjusting the position of the bolt 52 within the front bolt hole 421 and the intermediate bolt hole 51.
In this embodiment, the front bolt hole 421 is a vertically long hole and the intermediate bolt hole 51 is a horizontally long hole, but the front bolt hole 421 and the intermediate bolt hole 51 may be horizontally long holes and the intermediate bolt hole 51 may be vertically long holes.

<5> Building fixing member The building fixing member 6 is a steel member consisting of a back plate 61 that is approximately parallel to the surface of the pillar material 3, two upright portions 62 that stand upright from both ends of the width direction of the back plate 61 toward the pillar material 3, and a building fixing portion 63 that is bent from the end edge of the upright portions 62 outward in the width direction of the pillar material 3 and stands upright.
The building fixing member 6 abuts the back surface of the building fixing portion 63 against the surface of the pillar material 3 and is fixed with screws or the like (not shown).
The back plate 61 of the building fixing member 6 is spaced from the building fixing part 63 by the erection height of the erection part 62. By making this erection height higher than the height of the diaphragm 32 of the container house, the intermediate plate 5 and the fixing member 4 can be disposed in a position that does not interfere with the diaphragm 32. The erection part 62 and the fixing part 63 may be provided separately above and below the diaphragm 32.
A viscoelastic body 7 is adhered to the front surface of the back plate 61 of the building fixing member 6.

<6> Viscoelastic Body The viscoelastic body 7 is made of high-damping rubber, acrylic rubber, or the like.
One side of the viscoelastic body 7 is adhered to the back surface of the intermediate plate 5 and the other side is adhered to the front surface of the back plate 61 of the building fixing member 6, so that the fixing member 4, intermediate plate 5, and building fixing member 6 are integrated to form the vibration control device 1.
By bonding the intermediate plate 5 and the building fixing member 6 to both sides of the viscoelastic body 7, the viscoelastic body 7 deforms in accordance with the relative displacement of the intermediate plate 5 and the building fixing member 6, thereby providing vibration control.

<7> Vibration-damping structure of a container house using a vibration-damping device Next, a vibration-damping structure of a container house using the above-mentioned vibration-damping device 1 will be described.

<7.1> Configuration of the Lower Part of the Pillar An anchor bolt 91 to be embedded in the concrete foundation 2 is provided at the lower part of the pillar 3.
A lower vibration-damping member 8a of a predetermined thickness made of urethane, resin, or the like is placed on the upper surface of the concrete foundation 2 (FIG. 3).
A base plate 33 serving as the bottom plate of the pillar 3 is located on the upper surface of the lower vibration damping member 8a.
On the upper surface of the base plate 33, an upper vibration damping member 8b of a predetermined thickness made of urethane, resin or the like similar to the lower vibration damping member 8a is arranged, sandwiched between a steel lower anchor plate 92a and an upper anchor plate 92b.
The anchor bolt 91 erected from the concrete foundation 2 penetrates the lower vibration-damping member 8a, the opening 331 of the base plate 33, the lower anchor plate 92a, the upper vibration-damping member 8b, and the upper anchor plate 92b, and fixes the lower vibration-damping member 8a and the pillar material 3 onto the concrete foundation 2 by screwing an anchor nut 93 from above (Figure 4).
The lower vibration-damping member 8a is made of urethane, resin, etc., and is compressed by the weight of the container house. Therefore, the thickness of the lower vibration-damping member 8a is determined by calculating the amount of compression by the weight of the container house.
Since the lower vibration-damping member 8a is made of urethane, resin, or the like, it may be protected as a fireproof and waterproof measure by surrounding it with a steel protective material 81. The protective material 81 is sized so that the base plate 33 of the pillar material 3 can be placed inside.
In this embodiment, the lower vibration-damping member 8a is provided directly below the pillar material 3, and the upper vibration-damping member 8b is provided inside the pillar material 3, but if the bottom plate protrudes to the outside from the pillar material 3, the lower vibration-damping member 8a and the upper vibration-damping member 8b may be provided above and below the protruding bottom plate.

<7.2> Action of vibration control structure (i) Downward displacement (Figure 5)
When vibrations act on the container house, the lower vibration-damping member 8a is compressed, the pillar material 3 sinks, and the building fixing member 6 fixed to the pillar material 3 is displaced downward.
On the other hand, the fixed member 4 fixed to the concrete foundation 2 and the intermediate plate 5 on its back surface are not displaced.
Therefore, when the pillar 3 sinks due to vibration, a relative displacement occurs between the intermediate plate 5 and the building fixing member 6, causing the viscoelastic body 7 to deform and damping the vibration together with the lower vibration damping member 8a. In particular, the fixing member 4 is made of steel and is strong because the lower end of the side wall 43 is welded to the upper surface of the foundation fixing plate 41, so even if the amount of sinking of the pillar 3 is small, the relative displacement is reflected in the deformation of the viscoelastic body 7.

In addition, due to changes over time, the lower vibration-damping member 8a may become compressed, causing the pillar material 3 to sink, and the viscoelastic body 7 may remain in a deformed state.
At this time, by loosening the nut 53, the bolt 52 moves within the intermediate bolt hole 51, which is a vertically long hole, and the position of the intermediate plate 5 relative to the building fixing member 6 can be returned to its original position.

(ii) Upward displacement (Figure 6)
When vibrations act on the container house, the upper vibration member 8b is compressed, the pillar material 3 is lifted, and the building fixing member 6 fixed to the pillar material 3 is displaced upward.
On the other hand, the fixed member 4 fixed to the concrete foundation 2 and the intermediate plate 5 on its back surface are not displaced.
Therefore, when the column material 3 is lifted by vibration, a relative displacement occurs between the intermediate plate 5 and the building fixing member 6, causing the viscoelastic body 7 to deform and damping the vibration together with the upper vibration damping member 8b. In particular, the fixing member 4 is made of steel and is strong because the lower end of the side wall 43 is welded to the upper surface of the foundation fixing plate 41, so even if the amount of lift of the column material 3 is small, the relative displacement is reflected in the deformation of the viscoelastic body 7.

[Other Examples]
<1> Building configuration In the above Example 1, a vibration control structure for a container house in which a vibration control device is attached to the pillar material 3 of the container house is described. However, the vibration control device of the present invention can be applied as appropriate to any building that is fixed on a concrete foundation 2, not limited to container houses.
Furthermore, the building fixing member 6 is not limited to being attached to a pillar material 3, but may also be attached to a structural body such as a foundation.

<2> Shape of building fixing member (Example 2)
In the above-mentioned Example 1, the building fixing member 6 was composed of a back plate 61, erect portions 62 erected from both ends of the width of the back plate 61, and a building fixing portion 63 erected from an end edge of the erect portion 62, but it may also be composed of a flat plate having a predetermined thickness (Figures 7 and 8).
In addition, the size and number of the building fixing members 6 and the viscoelastic bodies 7 may be changed appropriately according to the vibration damping effect that is desired to be achieved.
By making the thickness of the flat plate thicker than the height of the head of the bolt 52, the bolt 52 will not interfere with the pillar material 3 (FIG. 9). If the thickness of the flat plate is made thicker than the height of the diaphragm 32, it can also be applied to the container house of the first embodiment.

<3> Regulation of the distance between the intermediate plate and the building fixing member by the rear bolt (Example 3, FIG. 10)
The intermediate plate 5 has intermediate bolt holes 54 for the rear surface, which are longitudinally long holes, near the upper and lower ends.
In addition, the back plate 61 of the building fixing member 6 has a back bolt hole 611 at a position corresponding to the back intermediate bolt hole 54 .
A rear nut 56 is screwed onto a rear bolt 55 inserted through the rear intermediate bolt hole 54 and the rear bolt hole 611 to determine the distance between the intermediate plate 5 and the building fixing member 6 and to prevent the intermediate plate 5 adhered to the building fixing member 6 by the viscoelastic body 7 from peeling off. Since the rear intermediate bolt hole 54 is a vertically long hole, the intermediate plate 5 can be displaced up and down relative to the rear plate 6.
Furthermore, the front plate 42 of the fixing member 4 has a rear bolt opening 423 at a position corresponding to the rear intermediate bolt hole 54. The rear bolt opening 423 is an opening large enough to allow the rear bolt 55 to move in the vertical direction ( FIG. 11 ) to the extent that the intermediate bolt hole 51 and the rear intermediate bolt hole 54 are combined, and in the horizontal direction, the same as the front bolt hole 421. As a result, even if the fixing member 4 is fixed to the upper surface of the concrete foundation 2 in an inclined state, vibration control can be performed without impeding the displacement of the intermediate plate 5 relative to the building fixing member 6.

<4> Displacement of the fixing member in the front-rear direction (Example 4)
The fixing member 4 may be configured by dividing it into a base fixing plate 41 and a front plate 42 (FIG. 12).
The foundation fixing plate 41 has side plates 411 standing on both sides.
The front plate 42 has side walls 43 extending substantially perpendicularly from both sides toward the foundation fixing plate 41 .
The lower portion of the side wall 43 of the front plate 42 can be fitted between the both side walls 43 of the base fixing plate 41 .
The side wall 43 has side wall bolt holes 431 .
The side plate 411 has side plate bolt holes 412 at positions corresponding to the side wall bolt holes 431 .
Then, by screwing a bottom nut 46 onto the bottom bolt 45 inserted into the side wall bolt hole 431 and the side plate bolt hole 412, the foundation fixing plate 41 and the front plate 42 are integrated together, and the front plate 42 can be displaced in the forward/backward direction relative to the foundation fixing plate 41, with the bottom bolt 45 as a fulcrum.
