Description

本発明は、上下振動する構造体を制振する制振装置に係わり、特に、高架式の高速道路や鉄道軌道、あるいは、橋梁を構成する床版といった水平構造体を有する構造物に適用されて、水平構造体の上下の振動を抑制するようにした上下振動制振装置に関するものである。   The present invention relates to a vibration damping device that dampens a structure that vibrates up and down, and is particularly applied to a structure having a horizontal structure such as an elevated highway, a railway track, or a floor slab constituting a bridge. The present invention relates to a vertical vibration damping device that suppresses vertical vibration of a horizontal structure.

近年、高架式の高速道路や鉄道軌道、あるいは、橋梁を構成する床版といった水平構造体を備えた構造物にあっては、交通振動や地振時等における床版の落下や破損等の被害を抑えるために種々の対策が施されている。   In recent years, for structures with horizontal structures such as elevated expressways, railway tracks, or floor slabs that form bridges, damage such as falling or breakage of floor slabs during traffic vibration or ground shaking, etc. Various measures have been taken to suppress this.

その対策の一つとして、本件出願人が先に提案した構造物の制振装置がある。
この制振装置は、平構造体の下部に所定間隔をおいて設けられた支持部間に、これらの支持部間の間隔よりも長い全長を有する張力部材を配設し、この張力部材の途中に、第1のリンク片を回動自在に連結するとともに、水平構造体に第2のリンク片を回動自在に連結し、これらの第1のリンク片の他端部と第2のリンク片の他端部とを回動自在に連結し、構造物を構成する構造体と、前記第1のリンク片と第2のリンク片との連結部との間に、これらの第1のリンク片と第2のリンク片を付勢することにより、前記張力部材に張力を与える付勢部材と、前記第1のリンク片と第2のリンク片の回動によって作動させられる緩衝部材とを設けて構成されている。
この制振装置は、既設の高速道路や鉄道軌道、橋梁に対しても施工が可能で、水平構造体の上下振動によって生じた変位を拡大させ、その拡大させた変位を緩衝部材で吸収・減衰させるもので、水平構造体の上下振動を効率よく、かつ効果的に抑制することができるものである(例えばPCT/JP02/13630号公報(第14頁、図1)参照)。
PCT/JP02/13630号公報(第14頁、図1)
As one of the countermeasures, there is a structure damping device previously proposed by the applicant.
In this vibration damping device, a tension member having an overall length longer than the interval between the support portions is disposed between the support portions provided at a predetermined interval below the flat structure, In addition, the first link piece is rotatably connected, and the second link piece is rotatably connected to the horizontal structure, and the other end portion of the first link piece and the second link piece are connected. These first link pieces are connected between a structure constituting the structure and a connecting portion between the first link piece and the second link piece. And a biasing member that applies tension to the tension member by biasing the second link piece, and a buffer member that is actuated by rotation of the first link piece and the second link piece. It is configured.
This vibration control device can also be applied to existing highways, railway tracks, and bridges. The displacement caused by the vertical vibration of the horizontal structure is expanded, and the expanded displacement is absorbed and attenuated by a buffer member. Therefore, vertical vibrations of the horizontal structure can be efficiently and effectively suppressed (see, for example, PCT / JP02 / 13630 (page 14, FIG. 1)).
PCT / JP02 / 13630 (page 14, FIG. 1)

上記した制振装置は、水平構造体に生じた上下振動をその直交方向である水平方向へ変位を拡大させ、その拡大させた水平方向の変位を緩衝部材で吸収・減衰させる構成を採用しているが、本件発明者は、リンクの改良によって、さらなる制振効果が得られることを見出した。   The vibration damping device described above employs a configuration in which the vertical vibration generated in the horizontal structure is expanded in the horizontal direction, which is the orthogonal direction, and the expanded horizontal displacement is absorbed and attenuated by the buffer member. However, the present inventor has found that further vibration suppression effects can be obtained by improving the link.

本発明は、本件出願人が先に提案した構造物の制振装置より、さらなる制振効果が期待でき、施工性(現場施工による)、保守・管理性、経済性をも向上することができる上下振動制振装置を提供することを目的とする。   The present invention can be expected to have further vibration control effects than the structural vibration control device previously proposed by the applicant, and can also improve workability (by on-site construction), maintenance / controllability, and economic efficiency. An object is to provide a vertical vibration damping device.

Furthermore, as shown in FIG. 2 (3), the pivot part of the front part of the first component rod 21, the base portion of the second component rod 22, and the tip portion of the fourth component rod 24 is, for example, a fourth The concave portion 24b formed at the front portion of the configuration rod 24 is formed and configured so that the two convex portions 21c and 22a can be swung.
In addition, it may replace with this recessed part 24b, may be formed in convex shape like convex parts 21c and 22a, and may be arrange | positioned between the convex part 21c and the convex part 22a.

さらに、凸部を二分割させ、ボルトなどの締結手段とシムなどで係合ピン25の締め込み力を可変させて、摩擦減衰力を調整可能に構成しても良い。
Further, the pivoting portion of the tip portion of the first component rod 21, the base portion of the second component rod 22, and the tip portion of the fourth component rod 24 is configured as shown in FIGS. 2 (4) and 2 (5). The mode may be arbitrary. That is, as shown in FIG. 2 (4), the tip portion of the first component rod 21 is a convex portion 21c, the base portion of the second component rod 22 is a concave portion 22b so as to straddle the convex portion 21c, and the concave portion 22b. As shown in FIG. 2 (5), the tip portion of the fourth component rod 24 is recessed as the recess portion 24c. 24d, and in the meantime, the base portion of the second component rod 22 may be a convex portion 22c, and the convex portion 22c and the convex portion 21c of the tip portion of the first component rod 21 may be pivotally attached.
Further, the convex portion may be divided into two parts, and the fastening force of the engagement pin 25 may be varied by a fastening means such as a bolt and a shim so that the friction damping force can be adjusted.

次に、以上のように構成された実施の形態1にかかる上下振動制振装置の動作説明をする。
実施の形態1にかかる上下振動制振装置は、交通荷重等によって床版Wに上下振動、例えば、床版Wが下方へ変位すると、第2構成杆22の先部が張架部材1によって回動可能に拘束されているために、第1構成杆21と第2構成杆22とで形成された略くの字状が、より撓んだ「く」の字状に変化する。
Next, the operation of the vertical vibration damping device according to the first embodiment configured as described above will be described.
In the vertical vibration damping device according to the first exemplary embodiment, when the floor slab W is displaced downward by the traffic load or the like, for example, when the floor slab W is displaced downward, the tip portion of the second component rod 22 is rotated by the stretching member 1. Since it is constrained so as to be movable, the substantially square shape formed by the first configuration rod 21 and the second configuration rod 22 changes to a more bent “<” shape.

これと同時に、基部が突出部W2の先部に支持された第3構成杆23と第4構成杆24とが上方へ回動するように移動する。このとき、図1において、二点鎖線で図示したように、床版Wの下方への変位量よりも、各部の枢着部の回転変位量の方が、大きくなると共に、第3構成杆23と第4構成杆24との交点である枢着部の変位量が、床版Wの下方への変位量よりも大きくなる。   At the same time, the third component rod 23 and the fourth component rod 24, whose base portions are supported by the tip portion of the protrusion W2, move so as to rotate upward. At this time, as illustrated by a two-dot chain line in FIG. 1, the rotational displacement amount of the pivotally attached portion of each part becomes larger than the downward displacement amount of the floor slab W, and the third component 23 The amount of displacement of the pivoting portion that is the intersection of the fourth component rod 24 is greater than the amount of downward displacement of the floor slab W.

このとき、夫々の枢着部は、摩擦減衰可能な所要の嵌め合い関係でもって枢着されていることから、回転抵抗を積極的に持たせた各枢着部が、振動を早く収束するように作用する。   At this time, each pivoting portion is pivotally attached with a required fitting relationship capable of friction damping, so that each pivoting portion having positive rotation resistance converges vibrations quickly. Act on.

また、これと同時に、第3構成杆23と第4構成杆24との交点である枢着部に設けられたウェイト26が床版Wの振動の動きと逆方向の動作をするために、床版Wの振動を相殺する作用が生じて、急速に振動が減衰する。
なお、このウェイトは、常時、第2構成杆22を介して張架部材1にプレテンションを付与しており、応力弛緩を補償している。
At the same time, the weight 26 provided at the pivoting portion that is the intersection of the third component cage 23 and the fourth component rod 24 operates in the direction opposite to the vibration of the floor slab W. The action of canceling the vibration of the plate W occurs, and the vibration is rapidly attenuated.
Note that this weight always applies pretension to the tension member 1 via the second component rod 22 to compensate for stress relaxation.

このように実施の形態1にかかる上下振動制振装置によれば、緩衝部材や付勢部材がなくても、制振効果を発揮することができ、しかも、第3構成杆23と第4構成杆24との接続部分である枢着部が、床版Wに生じた上下振動と動きと反対の動作をして、床版Wに生じた上下振動を相殺するように作用(枢着部の往復質量によって)するから、制振効果を発揮することができる。   As described above, according to the vertical vibration damping device according to the first embodiment, the damping effect can be exhibited without the buffer member and the biasing member, and the third configuration rod 23 and the fourth configuration are provided. The pivoting part, which is the connecting part with the heel 24, operates in the opposite direction to the vertical vibration generated in the floor slab W and acts to cancel the vertical vibration generated in the floor slab W (the pivoting part Therefore, the damping effect can be exhibited.

また、構成部材を削減したから低コスト化につながり、さらに、施工現場において容易に、かつ、スピーディに施工することができる。
また、床版の振動の動きと逆方向の動作をする第3構成杆の先部と第4構成杆との枢着部に所要重量のウェイトを設けたから、床版の振動を相殺する作用をより効果的にして、急速に上下振動を減衰することができる。
Further, since the number of constituent members is reduced, the cost can be reduced, and furthermore, construction can be easily and speedily performed at the construction site.
In addition, since the weight of the required weight is provided at the pivotal portion between the tip portion of the third component rod and the fourth component rod, which operates in the direction opposite to the movement of the vibration of the floor slab, the action of canceling the vibration of the floor slab More effectively, the vertical vibration can be attenuated rapidly.

(実施の形態2)
図3に示すように、実施の形態2にかかる上下振動制振装置は、実施の形態1で例示した上下振動制振装置において、第3構成杆23の先部と、第4構成杆24の基部とを、揺動可能に係合ピン25で枢着させて構成された枢着部と、突出部W2基部近傍の床版Wの底面と、を連絡するように架設され、床版Wの上下振動に伴って生じる上記の枢着部と床版Wとの距離変位を吸収・減衰させる緩衝部3を設け、さらに、各枢着部における摩擦抵抗を積極的に持たせて摩擦減衰と共に、あるいは摩擦抵抗を低減させて、緩衝部3で上下振動を吸収・減衰させた例である。また、実施の形態2にかかる上下振動制振装置は、ウェイト26を設けていないものを例示しているが、実施の形態1と同様、第3構成杆23の先部と第4構成杆24の基部との枢着部等にウェイト26を設けて良いものである。
なお、実施の形態1と同一構成の要素は、実施の形態1と同一符号を付して説明を省略し、実施の形態2において要部となる緩衝部3を説明する。
(Embodiment 2)
As illustrated in FIG. 3, the vertical vibration damping device according to the second exemplary embodiment is the same as the vertical vibration damping device illustrated in the first exemplary embodiment. The base portion is installed to be pivotally attached to the base plate W by the engaging pin 25 so as to be swingable, and the bottom surface of the floor slab W near the base of the protruding portion W2. Provided with a buffer part 3 for absorbing and attenuating the distance displacement between the pivot part and the floor slab W caused by the vertical vibration, and further having a frictional resistance in each pivot part with friction damping, Alternatively, the frictional resistance is reduced, and the vertical vibration is absorbed and damped by the buffer portion 3. Further, the vertical vibration damping device according to the second embodiment is exemplified by the one not provided with the weight 26. However, as in the first embodiment, the front portion of the third configuration rod 23 and the fourth configuration rod 24 are provided. A weight 26 may be provided at a pivot portion with respect to the base portion.
In addition, the element of the same structure as Embodiment 1 attaches | subjects the same code | symbol as Embodiment 1, description is abbreviate | omitted, and demonstrates the buffer part 3 used as the principal part in Embodiment 2. FIG.

緩衝部3は、圧縮バネ31と、オイルダンパーやエアダンパーなどのダンパー32とが一対のフラットバー状のフレーム33内に並設されると共にそのフレーム33から構成杆34を延出してなり、上記したように、第3構成杆23の先部と、第4構成杆24の基部とを、揺動可能に係合ピン25で枢着させて構成された枢着部と、突出部W2基部近傍の床版Wの底面と、を連絡するように架設されている。なお、図4に示すように、突出部W2基部に上記した構成杆34を枢着させても良い。   The shock absorber 3 is composed of a compression spring 31 and a damper 32 such as an oil damper or an air damper arranged in parallel in a pair of flat bar-shaped frames 33, and a construction rod 34 extending from the frame 33. As described above, the pivot portion formed by pivotally coupling the tip portion of the third component rod 23 and the base portion of the fourth component rod 24 with the engaging pin 25 so as to be swingable, and the vicinity of the base portion of the protrusion W2 It is constructed so as to communicate with the bottom surface of the floor slab W. In addition, as shown in FIG. 4, you may pivotally mount the above-mentioned structural rod 34 on the protrusion W2 base.

以上のように構成された実施の形態2にかかる上下振動制振装置は、実施の形態1と同様に、交通荷重等によって床版Wに上下振動、例えば、床版Wが下方へ変位すると、第2構成杆22の先部が張架部材1によって回動可能に拘束されているために、第1構成杆21と第2構成杆22とで形成された略くの字状が、より撓んだ「く」の字状に変化する。   Similarly to the first embodiment, the vertical vibration damping device according to the second embodiment configured as described above causes vertical vibrations on the floor slab W due to traffic load, for example, when the floor slab W is displaced downward, Since the tip portion of the second component rod 22 is rotatably constrained by the stretching member 1, the substantially square shape formed by the first component rod 21 and the second component rod 22 is more flexible. It changes to a letter “ku”.

これと同時に、基部が突出部W2の先部に支持された第3構成杆23と第4構成杆24とが上方へ回動するように移動する。
したがって、上記した枢着部と床版Wとの距離が、単に床版Wが下方へ移動した変位量よりも大きく伸縮し、その間に架設された緩衝部3が、床版Wに生じた上下振動を急速に減衰する。
At the same time, the third component rod 23 and the fourth component rod 24, whose base portions are supported by the tip portion of the protrusion W2, move so as to rotate upward.
Therefore, the distance between the pivoting portion and the floor slab W expands and contracts larger than the amount of displacement that the floor slab W has moved downward, and the buffer portion 3 installed between the upper and lower portions of the floor slab W Damping vibrations rapidly.

この実施の形態2にかかる上下振動制振装置によれば、支持部材で支持された床版Wに生じた上下振動を、リンク部2に効率よく拡大するように伝搬させ、さらに、第3構成杆23の先部と第4構成杆24とが枢着(回動可能に連結)される枢着部と、床版W底面とを連絡するように、その枢着部と床版W底面との間に緩衝部3を架設して、床版Wに生じた上下振動による上下の変位量より拡大された変位を吸収・減衰するから、制振効果を発揮することができる。   According to the vertical vibration damping device according to the second embodiment, the vertical vibration generated in the floor slab W supported by the support member is propagated to the link portion 2 so as to be efficiently expanded, and further the third configuration The pivot part and the bottom of the floor slab W are connected so that the pivot part where the front part of the collar 23 and the fourth component collar 24 are pivotally connected (movably connected) and the bottom of the floor slab W are connected. Since the shock absorber 3 is installed between the two and the displacement larger than the vertical displacement caused by the vertical vibration generated in the floor slab W is absorbed and attenuated, the damping effect can be exhibited.

(実施の形態3)
実施の形態3にかかる上下振動制振装置は、図5に示すように、実施の形態2で例示した緩衝部3の一構成部材である床版W側の構成杆34を、床版Wの両端の基部から床版W全長に対して略4分の1の距離離間した位置に枢着させた例(支持部材W1で両持支持された床版W間を、構成杆34と、床版Wの中間に垂設された突出部W2とで、4等配する)であり、その他の構成は実施の形態1及び2と同一であり、この実施の形態3も、実施の形態1と同様、第3構成杆23の先部と第4構成杆24の基部との枢着部等にウェイト26を設けて良いものである。なお、実施の形態1及び2と同一構成の要素は、実施の形態1及び2と同一符号を付して説明を省略する。
(Embodiment 3)
As shown in FIG. 5, the vertical vibration damping device according to the third exemplary embodiment is configured such that the structural plate 34 on the floor slab W side, which is one constituent member of the buffer unit 3 illustrated in the second exemplary embodiment, An example in which the base plate at both ends is pivotally attached to a position separated by a distance of about a quarter of the entire length of the floor slab W (the space between the floor slabs W supported on both ends by the support member W1 and the floor slab 34) The other parts are the same as those in the first and second embodiments, and the third embodiment is the same as the first embodiment. The weight 26 may be provided at a pivotal connection portion between the tip portion of the third configuration rod 23 and the base portion of the fourth configuration rod 24. Elements having the same configurations as those in the first and second embodiments are denoted by the same reference numerals as those in the first and second embodiments, and description thereof is omitted.

以上のように構成された実施の形態3にかかる上下振動制振装置は、図5において2点鎖線で図示したように、両持支持された床版Wに、単純な上下振動のみならず、上下にうねる振動が発生しても、突出部W2を境にして夫々の緩衝部が拡大された変位(上下振動)を吸収・減衰して、極めて効率的な制振効果を発揮することができる。   The vertical vibration damping device according to the third embodiment configured as described above is not only a simple vertical vibration on the both-supported floor slab W as illustrated by a two-dot chain line in FIG. Even when vibrations that swell up and down occur, each buffer part absorbs and attenuates the expanded displacement (vertical vibrations) with the protrusion W2 as a boundary, and an extremely efficient damping effect can be exhibited. .

(実施の形態4)
実施の形態3にかかる上下振動制振装置は、図6に示すように、実施の形態2で例示した緩衝部3を、第3構成杆23の先部と第4構成杆24の基部とが枢着される枢着部同士を連絡するように架設して、床版Wの上下振動に伴って生じる枢着部同士間の距離変位を吸収・減衰させつつ、第3構成杆23と第4構成杆24との接続部分である枢着部が、床版Wに生じた上下振動と動きと反対の動作をして、床版Wに生じた上下振動を相殺するように作用(枢着部の往復質量によって)させた例であり、その他の構成は実施の形態1及び2と同一であり、この実施の形態4も、実施の形態1と同様、第3構成杆23の先部と第4構成杆24の基部との枢着部等にウェイト26を設けて良いものである。なお、実施の形態1及び2と同一構成の要素は、実施の形態1及び2と同一符号を付して説明を省略する。
(Embodiment 4)
As shown in FIG. 6, the vertical vibration damping device according to the third exemplary embodiment includes the buffer portion 3 illustrated in the second exemplary embodiment, in which a tip portion of the third configuration rod 23 and a base portion of the fourth configuration rod 24 are provided. The third component rod 23 and the fourth component are constructed so as to connect the pivoted portions to be pivoted so as to absorb and attenuate the distance displacement between the pivoted portions caused by the vertical vibration of the floor slab W. The pivoting portion, which is a connecting portion with the component rod 24, operates in the opposite direction to the vertical vibration generated in the floor slab W and acts so as to cancel the vertical vibration generated in the floor slab W (the pivoting portion). The other configurations are the same as those in the first and second embodiments, and this fourth embodiment is similar to the first embodiment in that the front portion of the third configuration rod 23 and the second configuration are the same. A weight 26 may be provided at a pivot joint with the base portion of the four-component cage 24.

以上のように構成された実施の形態4にかかる上下振動制振装置は、図6において2点鎖線で図示したように、床版Wの上下振動に伴って生じた変位量よりも、枢着部同士間の距離変位を拡大させて伸縮状態で吸収・減衰させると同時に、第3構成杆23と第4構成杆24との接続部分である枢着部が、床版Wに生じた上下振動と動きと反対の動作をして、床版Wに生じた上下振動を相殺するように作用(枢着部の往復質量によって)するから、より制振効果を発揮することができる。   The vertical vibration damping device according to the fourth embodiment configured as described above is pivotally attached rather than the amount of displacement caused by the vertical vibration of the floor slab W, as illustrated by a two-dot chain line in FIG. While the distance displacement between the parts is enlarged and absorbed and attenuated in an expanded and contracted state, the pivoting part, which is the connecting part of the third component cage 23 and the fourth component cage 24, causes the vertical vibration generated in the floor slab W. Therefore, the vibration control effect can be further exerted by acting to reverse the vertical vibration generated in the floor slab W (by the reciprocating mass of the pivoting portion).
