Description

この発明は、大きな地震による振動から上部構造物等を保護する免震構造物及び制振構造物に設置されるダンパーの設置方法の技術分野に属し、更に云うと、限られた狭いスペースでも大型ダンパーを設置できる設置方法に関する。   The present invention belongs to the technical field of a seismic isolation structure that protects an upper structure and the like from vibration caused by a large earthquake and a method of installing a damper that is installed in a vibration control structure. The present invention relates to an installation method capable of installing a damper.

従来から風や地震の震動から建物を保護する免震構造物及び制振構造物に設置されるダンパーは、図５に示すように、先ず建物基礎４０と上部構造物４１との間に免震層４２が形成され、前記免震層４２に転がり支承とする支承材４３が設置されている。即ち建物基礎４０と上部構造物４１とに上位の台座４４ａと下位の台座４４ｂとで成る台座４４が設けられ、同上下の台座４４ａ、４４ｂとの間に水平方向に移動するボールベアリング４３ａが設置されている。更に隣接する台座４４、４４の略中間位置にはオイルダンパー４５が設置され、同オイルダンパー４５に、一方は前記上部構造物４１の床梁に接合され、他方は建物基礎４０に接合された支持構造体４６、４６を設けてそれぞれ連結して設置される構成である（下記の特許文献１を参照）。   Conventionally, a damper installed in a seismic isolation structure and a vibration control structure that protects a building from wind and earthquake vibrations is first isolated between a building foundation 40 and an upper structure 41 as shown in FIG. A layer 42 is formed, and a bearing material 43 is installed on the seismic isolation layer 42 as a rolling bearing. That is, the building base 40 and the upper structure 41 are provided with a pedestal 44 composed of an upper pedestal 44a and a lower pedestal 44b, and a ball bearing 43a that moves horizontally is installed between the upper and lower pedestals 44a and 44b. Has been. Further, an oil damper 45 is installed at a substantially intermediate position between the adjacent pedestals 44, 44, one of which is joined to the floor beam of the upper structure 41 and the other is joined to the building foundation 40. Structures 46 and 46 are provided and connected to each other (see Patent Document 1 below).

特開２００５−３６４９０号公報JP-A-2005-36490

上述した特許文献１の技術は、応力伝達の面で望ましい配置であることは認められる。しかし、台座４４とオイルダンパー４５とは、別々に間隔を空けて配置される構成である。それは、オイルダンパー４５の両端には、前記支持構造体４６、４６がそれぞれ連結されているからである。したがって、前記支持構造体４６、４６が台座４４、４４間のスパンを狭くさせてしまい、使用できるオイルダンパー４５の大きさを制限してしまう。   It is recognized that the technique of Patent Document 1 described above is a desirable arrangement in terms of stress transmission. However, the base 44 and the oil damper 45 are configured to be separately spaced. This is because the support structures 46 and 46 are connected to both ends of the oil damper 45, respectively. Therefore, the support structures 46 and 46 narrow the span between the pedestals 44 and 44, and limit the size of the oil damper 45 that can be used.

上記免震層４２において大きな変形を許容する場合、支承材４３とオイルダンパー４６のサイズを大きくする必要がある。しかし、支承材４３を大きくすることは、その上下の台座４４ａ、４４ｂの幅寸も大きくすることであり、必然的に隣接する台座４４、４４のスパンが狭くなる。その上、上述したようにオイルダンパー４５の両端に連結された前記支持構造体４６、４６が狭いスパンを更に狭くさせてしまう。そのため、大ストロークを期待できる大型のダンパーは使用できず、支承材４３のサイズを上げるのみとなり、効果的且つ合理的な免震性能を期待できないという問題点がある。   In the case where a large deformation is allowed in the seismic isolation layer 42, it is necessary to increase the sizes of the bearing material 43 and the oil damper 46. However, increasing the size of the support member 43 also increases the width of the upper and lower pedestals 44a and 44b, which inevitably reduces the span of the adjacent pedestals 44 and 44. In addition, as described above, the support structures 46 and 46 connected to both ends of the oil damper 45 further narrow the narrow span. Therefore, a large damper that can expect a large stroke cannot be used, and only the size of the bearing material 43 is increased, and there is a problem that an effective and rational seismic isolation performance cannot be expected.

仮に、図６に簡略化して示したように前記支持構造体４６を除去してスペースを確保し、大型オイルダンパー４５’を斜めに配置する方法が考えられるが、水平配置に比べてダンパー効率を著しく低下させてしまうし、免震層の階高を大きくする必要があることから実施することは至難である。
要するに、上記技術の問題点は、オイルダンパー４５を設置する高さ位置Ｍと同じ高さ位置に免震支承４３がくるよう上下の台座４４ａ、４４ｂの高さが設定されていることにある。 As shown in a simplified manner in FIG. 6, a method of removing the support structure 46 to secure a space and arranging a large oil damper 45 ′ obliquely can be considered. This is extremely difficult to implement because it significantly lowers the height of the seismic isolation layer.
In short, the problem of the above technique is that the heights of the upper and lower pedestals 44a and 44b are set so that the seismic isolation bearing 43 comes to the same height position as the height position M where the oil damper 45 is installed.

本発明の目的は、隣接する上下の台座の高さを段違いに形成して、大型のダンパーを限られた狭いスペースにおいても設置可能とし、免震性能を高める免震構造物及び制振構造物のダンパーの設置方法を提供することにある。   An object of the present invention is to provide a seismic isolation structure and a damping structure that improve the seismic isolation performance by forming the upper and lower pedestals adjacent to each other with different heights so that a large damper can be installed in a limited narrow space. It is to provide a method for installing a damper.

The bases installed above and below the seismic isolation bearings are formed in a so-called step difference where one side is higher due to the upper base and the other side is higher due to the lower base, and the damper is installed. Since the seismic isolation bearing does not come up at the height position, there is no need to interpose a damper mounting member such as a support structure between the pedestals, and a large damper that can expect a large stroke using the pedestal span to the maximum Can be actively deployed. In addition, the number of members can be reduced and work efficiency can be improved.

本発明は、下部構造物２と上部構造物３との間に免震層４を形成し、同免震層４の上部構造物３を支持する免震支承５、５間にダンパー７を設置する方法である。
前記免震支承５の上下に設ける台座６、（以下、反対側の台座６’を含む。）は、隣接する免震支承５の関係において、一方は上位の台座６ａのせいが高く、他方は下位の台座６ｂ’のせいが高い段違いに形成され、隣接する前記せいの高い台座６ａ、６ｂ’間にダンパー７をほぼ水平姿勢に設置している。 In the present invention, a seismic isolation layer 4 is formed between the lower structure 2 and the upper structure 3, and a damper 7 is installed between the seismic isolation supports 5 and 5 that support the upper structure 3 of the seismic isolation layer 4. It is a method to do.
The pedestals 6 provided on the upper and lower sides of the seismic isolation bearing 5 (hereinafter including the opposite pedestal 6 ') are highly related to the upper pedestal 6a in relation to the adjacent seismic isolation bearing 5, and the other is The lower pedestal 6b 'is formed in a high step, and the damper 7 is installed in a substantially horizontal position between the adjacent high pedestals 6a and 6b'.

請求項１に記載した本発明に係る免震構造物１のダンパー設置方法を図１に基づいて説明する。
本発明のダンパー設置方法は、免震構造物１において、基礎免震の免震層４や中間免震の免震層に好適に実施される。
実施例１においては基礎免震の免震層４に実施した場合を説明する。その態様は、図示の通り、下部構造物２（以下、建物基礎２とも云う。）と上部構造物３（又は鉄骨床梁）との間に免震層４が設けられた免震構造物１において、上部構造物３と、建物基礎２とに上位の台座６ａと下位の台座６ｂとで成る台座６が設けられ、前記上下の台座６ａ、６ｂとの間に免震支承５が設置される。前記隣接する台座６、６’間には、ほぼ水平姿勢に設置されたダンパー７が設置される構成とされている。図示例では前記免震支承５は積層ゴム、滑り支承とし、ダンパー７はオイルダンパー等の粘性ダンパー、低降伏点鋼等の履歴型ダンパー、粘弾性体ダンパーを使用する。 The damper installation method of the seismic isolation structure 1 which concerns on this invention described in Claim 1 is demonstrated based on FIG.
The damper installation method of the present invention is suitably implemented in the base isolation base isolation layer 4 and the intermediate isolation base isolation layer in the base isolation structure 1.
In Example 1, the case where it implements to the seismic isolation layer 4 of a basic seismic isolation is demonstrated. As shown in the figure, the seismic isolation structure 1 in which a seismic isolation layer 4 is provided between the lower structure 2 (hereinafter also referred to as building foundation 2) and the upper structure 3 (or steel floor beam). , A base 6 composed of an upper pedestal 6a and a lower pedestal 6b is provided on the upper structure 3 and the building foundation 2, and a seismic isolation bearing 5 is installed between the upper and lower pedestals 6a and 6b. . Between the adjacent pedestals 6 and 6 ', a damper 7 installed in a substantially horizontal posture is installed. In the illustrated example, the seismic isolation bearing 5 is a laminated rubber and a sliding bearing, and the damper 7 uses a viscous damper such as an oil damper, a hysteretic damper such as a low yield point steel, and a viscoelastic damper.

特に、免震支承５の上下に設ける台座６ａ、６ｂは、隣接する免震支承５の関係において、一方（図示上では右側）の上位の台座６ａを、そのせい（高さレベル）が下方に向かって高く形成され、下方の台座６ｂは上方に向かって低く形成される。前記上位の台座６ａは少なくとも高さ位置Ｍよりも下方で、後述するダンパー７の設置に支障をきたさない高さに形成する。   In particular, the bases 6a and 6b provided on the upper and lower sides of the base isolation bearing 5 are arranged so that one of the upper bases 6a (the right side in the drawing) is positioned downward because of the adjacent base isolation bearing 5 (height level). The lower pedestal 6b is formed lower toward the upper side. The upper pedestal 6a is formed at a height at least below the height position M so as not to hinder the installation of the damper 7 described later.

他方（図示例では左側）の下方の台座６ｂ’を、そのせい（高さレベル）が上方に向かって高く形成され、上位の台座６ａ’は下方に向かって低く形成する。下方の台座６ｂ’の高さは上述したように、高さ位置Ｍよりも高く形成する。   On the other side (left side in the illustrated example), the lower pedestal 6b 'is formed so that its height (height level) is higher upward, and the upper pedestal 6a' is formed lower downward. The height of the lower base 6b 'is formed higher than the height position M as described above.

上記の構成は、要するに右側の上下の台座６ａ、６ｂと左側の上下の台座６ａ’、６ｂ’のせいの高さを段違い形成するものである。
この段違いを形成したことにより、ダンパー７が配置される免震層４内の高さ位置Ｍ（中間レベル）に免震支承５が存在しなくなる。従って、隣接する台座６、６’との間に支持構造物等のダンパー取り付け部材等を介在する必要が無くなり、せいの高い台座６ａ、６ｂ’との間に直接的にダンパー７をほぼ水平姿勢に設置できる構造となる。
斯くすると、前記台座間のスペースを最大限に活用するべく、前記隣接する台座６と６’との間に大ストロークを期待できる大型のオイルダンパー７を設置することができる（請求項３記載の発明）。 In short, the above-described configuration forms the heights of the upper and lower pedestals 6a and 6b on the right side and the upper and lower pedestals 6a 'and 6b' differently.
By forming this step difference, the base isolation bearing 5 does not exist at the height position M (intermediate level) in the base isolation layer 4 where the damper 7 is disposed. Therefore, it is not necessary to interpose a damper mounting member such as a support structure between the adjacent pedestals 6 and 6 ', and the damper 7 is placed almost horizontally between the high pedestals 6a and 6b'. It becomes a structure that can be installed in.
In this case, a large oil damper 7 that can expect a large stroke can be installed between the adjacent pedestals 6 and 6 ′ in order to make maximum use of the space between the pedestals. invention).

次に、せいの高い台座６ａ、６ｂ’とダンパー７との接合方法について説明する。免震支承５を介在させる台座６、６’は所謂キャピタル構造であり、予め前記せいの高い台座６ａ、６ｂ’のダンパー設置箇所に、先端に固定材を有するネジ穴８が設けられている。前記ダンパー７を台座６、６’の高さ位置Ｍへ位置合わせし、前記ネジ穴８へＰＣ鋼棒等の引張材９をねじ込んで同ダンパー７を接合する。   Next, a method for joining the high pedestals 6a and 6b 'to the damper 7 will be described. The pedestals 6 and 6 ′ with the seismic isolation bearing 5 interposed therebetween have a so-called capital structure, and a screw hole 8 having a fixing material at the tip is provided in advance in the damper installation location of the high pedestals 6 a and 6 b ′. The damper 7 is aligned with the height position M of the bases 6 and 6 ′, and a tensile material 9 such as a PC steel rod is screwed into the screw hole 8 to join the damper 7.

本発明の実施形態はこの限りではなく、図２に示すように、一方の台座６（右側）は、その下位の台座６ｂを建物基礎２に埋め込み、その高さレベルを同建物基礎２の上面と一致して設けている。また、他方の台座６’（左側）は、その上位の台座６ａ’を上部構造物３に埋め込み、その高さレベルを同上部構造物３の上面と一致して設けることで段違いを形成して実施しても良い。この場合、実施例１のように上位の台座６ａ（６ａ’）と、下位の台座６ｂ（６ｂ’）のそれぞれ別々の型枠を設置する必要がなくなり、一回の型枠施工で実施できるので作業効率が向上する。前記埋め込まれる台座６ｂ及び６ａ’は免震支承５の取り付け部である。   The embodiment of the present invention is not limited to this, and as shown in FIG. 2, one pedestal 6 (right side) embeds a lower pedestal 6 b in the building foundation 2, and its height level is the upper surface of the building foundation 2. It is provided in line with. Further, the other pedestal 6 ′ (left side) forms a difference by embedding the upper pedestal 6a ′ in the upper structure 3 and providing the height level thereof to coincide with the upper surface of the upper structure 3. You may carry out. In this case, it is not necessary to install separate molds for the upper pedestal 6a (6a ′) and the lower pedestal 6b (6b ′) as in the first embodiment. Work efficiency is improved. The pedestals 6 b and 6 a ′ to be embedded are attachment portions of the seismic isolation bearing 5.

本発明の実施形態はこの限りではなく、図３に示すように、実施例１と実施例２を併合させて実施することもできる。つまり、一方（右側）は実施例２の如く上位の台座６ａ（図示省略）が上部構造物３へ埋め込まれる構成とされ、他方（左側）は実施例１の如く上位の台座６ａ’のせいを高く下位の台座６ｂ’のせいを低く構成してそれぞれ配置した構成である。   The embodiment of the present invention is not limited to this, and as shown in FIG. 3, the first embodiment and the second embodiment can be combined. That is, one (right side) is configured such that the upper pedestal 6a (not shown) is embedded in the upper structure 3 as in the second embodiment, and the other (left side) is caused by the upper pedestal 6a 'as in the first embodiment. This is a configuration in which the upper and lower pedestals 6b 'are configured to be low and arranged respectively.

次に、請求項２に記載した制振構造物１０のダンパー設置方法を差異点のみ説明する。本実施例４は上記実施例１〜３とほぼ同様の技術的思想を有している。その差異点は図４に示すように、本発明を上部構造物３０（以下、高層建物とも云う。）を制振マスとする制振構造物１０の柔剛性層４０（剛性を小さく、柔剛性として変位させている層）に実施する点にあり、一例として、制振構造物１０を、本体部分である住戸２０とスカイラウンジとヘリポートなどから成る高層建物３０とに縁切りし、その間に形成した柔剛性層４０に実施する。
その他、台座６、６’及びダンパー７の取り付け方法においては上述したとおりであるため説明及び図示する事は省略する。 Next, only the differences in the damper installation method for the vibration damping structure 10 described in claim 2 will be described. The fourth embodiment has the same technical idea as the first to third embodiments. As shown in FIG. 4, the difference is that the flexible structure layer 40 of the vibration control structure 10 having the upper structure 30 (hereinafter also referred to as a high-rise building) as the vibration control mass is used. As an example, the damping structure 10 is cut into a high-rise building 30 consisting of a main unit dwelling unit 20 and a sky lounge and a heliport, and formed between them. This is performed on the flexible layer 40.
In addition, since the mounting method of the bases 6 and 6 'and the damper 7 is as described above, the description and illustration thereof are omitted.

以上に本発明の実施例を説明したが、本発明はこうした実施例に何ら限定されるものではなく、本発明の要旨を逸脱しない範囲において、種々の形態で実施し得る。   Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments and can be implemented in various forms without departing from the gist of the present invention.
