Description

本発明は、基礎に支持され構造物を支持する基礎構造に係る。   The present invention relates to a foundation structure that is supported by a foundation and supports a structure.

地震が発生すると、建物、構造物等の構造体が水平、垂直に揺すられる。
地震等による加速度レベルが大きいと、構造体が損傷をうけたり、構造体の中にあるものが予想を越えて加速度を受けたり、予想を超える変位をうけたりする。
そこで、基礎から構造体へ伝達する振動エネルギーを減少させて振動を免震する免震機能をもつ基礎構造、または構造体が振動した際に振動エネルギーを吸収し振動レベルを小さくして振動を制振する制振機能を持つ基礎構造が提案される。 When an earthquake occurs, structures such as buildings and structures are shaken horizontally and vertically.
When the acceleration level due to an earthquake or the like is large, the structure is damaged, or an object in the structure receives an acceleration exceeding an expectation or a displacement exceeding the expectation.
Therefore, by reducing the vibration energy transmitted from the foundation to the structure, the foundation structure has a seismic isolation function to isolate the vibration, or when the structure vibrates, it absorbs the vibration energy and reduces the vibration level to control the vibration. A basic structure with vibration damping function is proposed.

例えば、基礎構造は複数の免震機構で構成される。
免震機構は、基礎と構造物との水平方向の相対移動に応じて水平反力を発生させる。
免震機構には、各種の形式のものがある。
例えば、免震機構は多段に重ねられた複数のゴム板と複数の鉄板とで構成される。
基礎と構造物との水平方向の相対移動が生じると、複数のゴム板と複数の鉄板との間に摩擦が発生する。
例えば、免震機構は水平方向に沿って直動可能なリニアガイドで構成される。
基礎と構造物との水平方向の相対移動が生じると、リニアガイドに摩擦が発生する。リニアガイドに発生する摩擦力は小さいので、比較的長周期の応答に優れる。 For example, the foundation structure is composed of a plurality of seismic isolation mechanisms.
The seismic isolation mechanism generates a horizontal reaction force according to the horizontal relative movement between the foundation and the structure.
There are various types of seismic isolation mechanisms.
For example, the seismic isolation mechanism is composed of a plurality of rubber plates and a plurality of iron plates stacked in multiple stages.
When the horizontal relative movement between the foundation and the structure occurs, friction occurs between the plurality of rubber plates and the plurality of iron plates.
For example, the seismic isolation mechanism is composed of a linear guide that can move linearly along the horizontal direction.
When the horizontal relative movement between the foundation and the structure occurs, friction is generated in the linear guide. Since the frictional force generated in the linear guide is small, the response with a relatively long period is excellent.

基礎構造は、異なる形式の免震機構の組合せで構成されることがある。
免震機構は、その形式に固有の周波数特性をもつ。
また、免震機構は、その形式に固有の垂直剛性を持つ。
異なる形式の免震機構の組合せで構成されるた基礎構造は、幅広い周波数特性をもつことができるという特徴をもつ。
その反面、異なる形式の免震機構は異なる垂直剛性をもつことが多いので、異なる形式の免震機構の間で、構造体に加速度が生じていないときにも、不陸が生ずるおそれがある。特に、構造体に加速度が生じるときに、不陸が生ずるおそれが大きくなる。 The foundation structure may consist of a combination of different types of seismic isolation mechanisms.
The seismic isolation mechanism has frequency characteristics inherent to its type.
In addition, the seismic isolation mechanism has a vertical rigidity inherent to its type.
The foundation structure composed of a combination of different types of seismic isolation mechanisms has the feature that it can have a wide range of frequency characteristics.
On the other hand, since different types of seismic isolation mechanisms often have different vertical stiffnesses, unevenness may occur between the different types of seismic isolation mechanisms even when the structure is not accelerated. In particular, when acceleration occurs in the structure, the risk of unevenness increases.

また、基礎構造が複数の免震機構で構成される場合に、構造体に大きな加速度が生ずると、上からみて周辺に配された免震機構の取り付け部に大きな引き抜き力が生ずる。
この引き抜き力による構造体の床の不陸を押さえるために、周辺に垂直剛性のおおきな免震機構を配すると、引き抜き力が大きくなる現象が生ずる。 Further, when the foundation structure is composed of a plurality of seismic isolation mechanisms, if a large acceleration is generated in the structure, a large pulling force is generated at the mounting portion of the seismic isolation mechanisms arranged in the vicinity as viewed from above.
In order to suppress the unevenness of the floor of the structure due to this pulling force, if a large seismic isolation mechanism with a large vertical rigidity is arranged in the vicinity, a phenomenon that the pulling force becomes large occurs.

また、構造体の免震機構に支持される箇所が免震機構から一時的に離間することを許容する様にすると、引き抜き力が大きくなことを抑制できる。
しかし、構造体の免震機構に支持される箇所が免震機構から一時的に離間した後で、加速度が作用しないとき姿勢に復帰する際に大きな衝撃力が発生することがある。 Further, if the portion of the structure supported by the seismic isolation mechanism is allowed to be temporarily separated from the seismic isolation mechanism, it is possible to suppress an increase in the pulling force.
However, after the part of the structure supported by the seismic isolation mechanism is temporarily separated from the seismic isolation mechanism, a large impact force may be generated when returning to the posture when no acceleration is applied.

本発明は以上に述べた問題点に鑑み案出されたもので、簡易な構成で基礎に支持され構造物を支持するのに適した基礎構造を提供しようとする。   The present invention has been devised in view of the above-described problems, and an object of the present invention is to provide a foundation structure that is supported by a foundation with a simple configuration and that is suitable for supporting a structure.

従って、簡易な構成で基礎に支持され構造物を支持するのに適した基礎構造を提供できる。 As described above, the basic structure according to the present invention has the following effects due to its configuration.
The shock absorber and the seismic isolation mechanism connected in series in the vertical direction support the structure, and the shock absorber includes the first member, the first elastic body, the second member, and the second elastic body. When the overlapping members are fastened together with the tension member, and the first member and the second member sandwich the first elastic body elastically, different forces act on a plurality of seismic isolation mechanisms. In addition, the first elastic body and the second elastic body are respectively compressed to change the separation distance between the first mounting surface and the second mounting surface, and the support points supported by the plurality of seismic isolation mechanisms You can adjust the unevenness that occurs during.
Further, since the first elastic body and the second elastic body are pre-compressed when the acceleration does not act on the foundation structure, the acceleration acts on the foundation structure and different forces are applied to the plurality of seismic isolation mechanisms. When acting, it is difficult for rattling to occur in the separation distance between the first member and the second member, and unevenness generated between support points supported by a plurality of seismic isolation mechanisms can be adjusted.
The shock absorber has one of the first mounting surface and the second mounting surface fixed to the lower part of the structure, and the other of the first mounting surface or the second mounting surface fixed to the upper part of the seismic isolation mechanism. As a result, when different forces act on multiple seismic isolation mechanisms, the separation distance between the lower part of the structure and the upper part of the seismic isolation device changes, and the support supported by the multiple seismic isolation mechanisms You can adjust the unevenness that occurs between points.
In addition, since the vertical stiffness of the first seismic isolation mechanism is different from the vertical stiffness of the second seismic isolation mechanism, the first seismic isolation mechanism and the second seismic isolation mechanism having different frequency characteristics are employed. Thus, it is possible to give good seismic isolation characteristics to a wide frequency as a whole while adjusting the unevenness generated between the support points supported by a plurality of seismic isolation mechanisms.
In addition, a plurality of the first seismic isolation devices having a plurality of rubber plates and a plurality of iron plates stacked in multiple stages, and a plurality of the second seismic isolation devices having a linear guide that can move linearly along the horizontal direction. Each structure is supported, and the shock absorber is placed between at least one of the first seismic isolation mechanism or the second seismic isolation mechanism and the structure, so it is good for relatively high frequencies. Combining the first seismic isolation device with excellent seismic isolation characteristics with the second seismic isolation device with good seismic isolation characteristics at a relatively low frequency provides good seismic isolation characteristics over a wide frequency range. I can give it.
Further, a plurality of the second seismic isolation mechanisms are arranged around the first seismic isolation mechanisms as viewed from above, and the shock absorber and the second seismic isolation mechanism are connected in series in the vertical direction. Therefore, when a large acceleration is applied, the pulling force generated in the second seismic isolation mechanism arranged on the outer periphery can be alleviated, and good seismic isolation characteristics can be provided.
In addition, when assuming that the assumed acceleration acts, N seismic isolation mechanisms and a plurality of shock absorbers on which an upward vertical load acts are connected in series in the vertical direction to support the structure. When an acceleration equivalent to the assumed acceleration is applied, the pulling-out force generated in the seismic isolation mechanism in which the vertical load is applied upward can be relaxed, and a good seismic isolation control characteristic can be provided.
In addition, since the N seismic isolation mechanisms supporting a vertical load smaller than the assumed vertical load and a plurality of shock absorbers are connected in series in the vertical direction when acceleration is not applied, the structure is supported. When acceleration that generates a vertical load larger than the assumed vertical load is applied, the pull-out force generated in the base isolation mechanism, which may be affected by the vertical load upward, is alleviated to provide good seismic isolation characteristics. I can give it.
In addition, since the first member and the second member do not contact in the vertical direction when the acceleration does not act on the foundation structure, the first member and the second member are The first elastic body can be further compressed to change the separation distance, thereby providing good seismic isolation characteristics.
Moreover, since at least one part of said 1st member or said 2nd member was embedded in the concrete frame of a structure, the clearance gap height between a structure and a foundation can be made low.
Therefore, the foundation structure suitable for supporting the structure supported by the foundation with a simple configuration can be provided.

複数の免震機構１００が、互いに異なる垂直剛性をもつことがある。
例えば、第一免震機構１１０の垂直剛性と第二免震機構１２０の垂直剛性は、互いに異なる。
構造物５０の重量が変化した場合に、複数の免震機構１００の沈み込み量に垂直剛性の差によるばらつきが生ずる。
このような現象が発生したときに、複数の免震機構１００に各々に直列に繋がった緩衝器２００の第一取付面Ｓ１と第二取付面Ｓ２との離間距離が各々に変化するので、基礎構造が支持する構造体の各々の支持点での不陸が緩和される。

The plurality of seismic isolation mechanisms 100 may have different vertical stiffnesses.
For example, the vertical stiffness of the first seismic isolation mechanism 110 and the vertical stiffness of the second seismic isolation mechanism 120 are different from each other.
When the weight of the structure 50 changes, the amount of subsidence of the plurality of seismic isolation mechanisms 100 varies due to the difference in vertical rigidity.
When such a phenomenon occurs, the separation distance between the first mounting surface S1 and the second mounting surface S2 of the shock absorber 200 connected in series to each of the plurality of seismic isolation mechanisms 100 changes. The unevenness at each supporting point of the structure supported by the structure is alleviated.

Generally, when the foundation structure is viewed from above, there is a tendency that a large pulling force acts on the seismic isolation mechanisms 100 arranged around the center rather than the center.
In such a case, the second elastic body 220 of the shock absorber 200 connected in series to the seismic isolation mechanism 100 on which a large pulling force is applied is greatly compressed.
As a result, the drawing force is alleviated from being concentrated on the specific seismic isolation mechanism 100.

引き抜き力が小さくなると、構造体の支持点が下降して緩衝器２００の第一部材２３０と第二部材２４０が第二弾性体２２０を上下方向に圧縮する。
その結果、仮に第二弾性体２２０がない場合に比べて、支持点に生ずる力が緩和される。 Next, operation 3 of the basic structure according to the first embodiment of the present invention will be described with reference to the drawings.
The left figure of FIG. 11 shows the 3rd effect | action of the buffer concerning 1st embodiment of this invention.
When a large pulling force acts on a specific seismic isolation mechanism, the second elastic body 220 of the shock absorber 200 is compressed by the second action, and the support point of the structure is displaced upward.
When the pulling force is reduced, the support point of the structure is lowered, and the first member 230 and the second member 240 of the shock absorber 200 compress the second elastic body 220 in the vertical direction.
As a result, compared with the case where there is no second elastic body 220, the force generated at the support point is reduced.

また、特定の免震機構に大きな引き抜き力が作用すると、引き抜き力の作用により緩衝器２００の第二弾性体２２０が圧縮して、構造体の支持点が上方に変位し、引き抜き力が小さくなると、構造体の支持点が下降して緩衝器２００の第一部材２３０と第二部材２４０が第二弾性体２２０を上下方向に圧縮するので、仮に第二弾性体２２０がない場合に比べて、支持点に生ずる力が緩和される。
また、免震機構１００による支持力が構造物の支持面の一点に集中する場合に、免震機構とっ構造物の間に複数の緩衝器２００を介在させることで、免震機構１００の周囲の不陸を緩和できる。

また、第二免震機構と緩衝器を直列にしたもので構造物を支持すると、アンカーボルト６０を簡略化でき、鉛直剛性を調製でき、浮上り後の衝撃を緩和できる。
また、第一免震機構と緩衝器を直列にしたものと第二免震機構と緩衝器を直列にしたものとを並列にしたもので構造物を支持してもよい。 The foundation structure which concerns on embodiment of this invention has the following effects by the structure.
The shock absorber 200 and the seismic isolation mechanism 100 connected in series support the structure 50, and the shock absorber 200 overlaps the first member 230, the first elastic body 210, the second member 240, and the second elastic body 220. Since the first member 230 and the second member 240 can be compressed with the first elastic body 210 sandwiched between the tension members 250, when different forces act on the plurality of seismic isolation mechanisms, The first elastic body 210 and the second elastic body 220 are compressed to each other, and the separation distance between the first member 230 and the second member 240 is changed to be generated between support points supported by a plurality of seismic isolation mechanisms. Can adjust the unevenness.
In addition, since the first elastic body 210 and the second elastic body 220 are precompressed when the acceleration does not act on the foundation structure, the acceleration acts on the foundation structure and different forces are applied to the plurality of seismic isolation mechanisms. When acting, the distance between the first member 230 and the second member 240 is less likely to be loose, and the unevenness that occurs between the support points supported by the plurality of seismic isolation mechanisms can be adjusted.
In addition, since the shock absorber 200 has the first mounting surface S1 fixed to the lower part of the structure and the second mounting surface S2 fixed to the upper part of the seismic isolation mechanism 100, different force is applied to the plurality of seismic isolation mechanisms 100. , The separation distance between the lower part of the structure and the upper part of the seismic isolation device 100 changes, and the unevenness generated between the support points supported by the plurality of seismic isolation mechanisms 100 can be adjusted.
Also, since the vertical stiffness of the first seismic isolation mechanism 110 and the vertical stiffness of the second seismic isolation mechanism 120 are different, the first seismic isolation mechanism 110 and the second seismic isolation mechanism 120 having different frequency characteristics are used in combination. Thus, it is possible to give good seismic isolation characteristics to a wide frequency as a whole while adjusting the unevenness generated between the support points supported by the plurality of seismic isolation mechanisms 100.
In addition, a plurality of first seismic isolation devices 110 having a plurality of rubber plates and a plurality of iron plates stacked in multiple stages, and a plurality of second seismic isolation devices 120 having linear guides that can move linearly along the horizontal direction. Since the structure 50 is supported and the shock absorber 200 is placed between one of the first seismic isolation mechanism 110 and the second seismic isolation mechanism 120 and the structure, it is possible to obtain a good isolation at a relatively high frequency. Combining the first seismic isolation device 110 having seismic control characteristics with the second seismic isolation device 120 having good seismic isolation characteristics at a relatively low frequency to provide good seismic isolation characteristics at a wide frequency range. Can do.
In addition, a plurality of first seismic isolation devices 110 having a plurality of rubber plates and a plurality of iron plates stacked in multiple stages, and a plurality of second seismic isolation devices 120 having linear guides that can move linearly along the horizontal direction. Since the structure 50 is supported and the shock absorber 200 is placed between both the first seismic isolation mechanism 110 or the second seismic isolation mechanism 120 and the structure, the seismic isolation system is excellent at a relatively high frequency. By combining the first seismic isolation device 110 having vibration characteristics and the second seismic isolation device 120 having good seismic isolation characteristics at a relatively low frequency, it is possible to provide good seismic isolation characteristics over a wide frequency range. .
In addition, a plurality of second seismic isolation mechanisms 120 are arranged around the first seismic isolation mechanisms 110 as viewed from above, and the shock absorber 200 and the second seismic isolation mechanism 120 are connected in series in the vertical direction. Since the object is supported, when a large acceleration is applied, the pulling force generated in the second seismic isolation mechanism 120 arranged on the outer periphery can be relaxed, and a good seismic isolation characteristic can be provided. .
In addition, since the first elastic body 210 can be compressed by preventing the first member 230 and the second member 240 from contacting each other when the acceleration does not act on the foundation structure, The one member 230 and the second member 240 can compress the first elastic body 210 to change the separation distance, thereby providing good seismic isolation characteristics.
Moreover, since at least a part of the first member 230 is embedded in the concrete frame of the structure, the gap height between the structure and the foundation can be reduced.
In addition, when the foundation structure is viewed from above, there is a tendency for a large pulling force to act on the seismic isolation mechanism 100 arranged around the center, and in such a case, the seismic isolation mechanism to which a large pulling force is applied. Since the second elastic body 220 of the shock absorber 200 connected in series to 100 is greatly compressed, it is possible to reduce the concentration of the pulling force on the specific seismic isolation mechanism 100.
Further, when assuming that the assumed acceleration is applied, N seismic isolation mechanisms 100 and a plurality of shock absorbers 200 on which an upward vertical load is applied are connected in series in the vertical direction to support the structure. Therefore, when an acceleration equivalent to the assumed acceleration is applied, the pulling-out force generated in the seismic isolation mechanism 100 in which the vertical load is applied upward can be alleviated, and good seismic isolation characteristics can be provided.
In addition, when the acceleration does not act, N seismic isolation mechanisms 100 that support a vertical load smaller than a specific vertical load and a plurality of shock absorbers 200 are connected in series in the vertical direction to support the structure. Therefore, when an acceleration that generates a vertical load larger than the set vertical load is applied, the pull-out force generated in the seismic isolation mechanism 100 that may be applied with the vertical load upward is alleviated, and good seismic isolation control is achieved. It can have characteristics.
Further, when a large pulling force acts on a specific seismic isolation mechanism, the second elastic body 220 of the shock absorber 200 is compressed by the action of the pulling force, the support point of the structure is displaced upward, and the pulling force becomes small. Since the support member of the structure is lowered and the first member 230 and the second member 240 of the shock absorber 200 compress the second elastic body 220 in the vertical direction, compared to the case where the second elastic body 220 is not provided, The force generated at the support point is reduced.
Further, when the supporting force by the seismic isolation mechanism 100 is concentrated on one point of the support surface of the structure, a plurality of shock absorbers 200 are interposed between the seismic isolation mechanism and the structure, so that Can relieve unevenness.
In addition, if the structure is supported by the first seismic isolation mechanism and the shock absorber in series, the pulling force can be reduced and the impact after rising can be reduced.
Further, when the structure is supported by the second seismic isolation mechanism and the shock absorber in series, the anchor bolt 60 can be simplified, the vertical rigidity can be adjusted, and the impact after lifting can be reduced.
Moreover, you may support a structure by what paralleled the thing which connected the 1st seismic isolation mechanism and the shock absorber in series, and the thing which connected the 2nd seismic isolation mechanism and the shock absorber in series.
