特開２０１１－１４０７５８号公報JP 2011-140758 A

特許文献１に記載の建築物の基礎構造では、例えば、高層側基礎や低層側基礎がその下方の杭にて荷重を支持する杭基礎等である場合には、その杭の仕様を、水平荷重を負担できる費用や手間のかかる仕様とする必要があり、コストダウンや省人化を図り難いという不都合がある。
この実情に鑑み、本発明の主たる課題は、高層側基礎と低層側基礎を有する建築物の基礎構造において、効率良くコストダウンや省人化を図れる合理的な基礎構造を提供する点にある。 In the foundation structure of the building described in Patent Document 1, for example, when the high-rise side foundation and the low-rise side foundation are pile foundations that support the load with the piles below them, the specifications of the piles are adjusted to the horizontal load. Therefore, it is difficult to reduce costs and save manpower.
In view of this situation, the main object of the present invention is to provide a rational foundation structure that can efficiently reduce costs and save labor in the foundation structure of a building having a high-rise foundation and a low-rise foundation.

本発明の第１特徴構成は、低層側建物よりも重量の大きい高層側建物を支持する高層側基礎と、前記高層側建物に隣接する前記低層側建物を支持する低層側基礎とを有する建築物の基礎構造であって、
前記高層側基礎と前記低層側基礎とが水平荷重を伝達可能なように一体化され、
前記低層側基礎とその下方の低層側基礎支持部との間に、水平力の伝達を回避するための水平力伝達回避手段が介在され、
前記低層側建物に作用する水平荷重を、前記低層側基礎を介して前記低層側基礎支持部に伝達するのを前記水平伝達回避手段により回避して前記低層側基礎を介して前記高層側基礎に伝達して前記低層側基礎の側で負担せずに前記高層側基礎の側で負担するように構成されている点にある。 A first characteristic configuration of the present invention is a building having a high -rise side foundation that supports a high-rise side building that is heavier than a low-rise side building, and a low-rise side foundation that supports the low-rise side building adjacent to the high-rise side building. the underlying structure of
The high-rise side foundation and the low-rise side foundation are integrated so as to be able to transmit a horizontal load,
Horizontal force transmission avoiding means for avoiding transmission of horizontal force is interposed between the low-rise side foundation and the lower-rise side foundation support portion below it,
The horizontal load acting on the low-rise side building is transferred to the high-rise side foundation via the low-rise side foundation by avoiding the transmission of the horizontal load acting on the low-rise side building to the low-rise side foundation support portion via the low-rise side foundation by the horizontal transmission avoidance means. It is characterized in that it is constructed so that the side of the foundation on the high-rise side bears the burden without transmitting it to the side of the foundation on the low-story side.

本構成によれば、低層側建物に作用する水平荷重を低層側基礎の側で負担しないので、その分、低層側基礎やその下方の低層側基礎支持部の構造を簡略化することができる。また、高層側基礎は、低層側建物よりも荷重の大きい高層側建物を支持するように設計されるので、高層側基礎の側にて低層側建物分の水平荷重を追加的に負担することによる構造上の影響も限定的である。よって、効率良くコストダウンや省人化を図ることができる。更に、高層側基礎と低層側基礎とを一体化することで、高層側建物と低層側建物とを近接配置することも可能となり、設計の自由度を向上させることができる。 According to this configuration, since the horizontal load acting on the low-rise side building is not borne by the low-rise side foundation side, the structure of the low-rise side foundation and the low-rise side foundation support section below it can be simplified accordingly. In addition, since the high-rise side foundation is designed to support the high-rise side building, which has a larger load than the low-rise side building, the horizontal load of the low-rise side building is additionally borne by the high-rise side foundation. Structural impact is also limited. Therefore, it is possible to efficiently reduce costs and save manpower. Furthermore, by integrating the high-rise side foundation and the low-rise side foundation, it becomes possible to arrange the high-rise side building and the low-rise side building close to each other, and the degree of freedom in design can be improved.

また、本構成によれば、低層側基礎とその下方の低層側基礎支持部との間に介在された水平力伝達回避手段により、低層側基礎から低層側基礎支持部への水平力の伝達が回避されるので、低層側建物に作用する水平荷重を、低層側基礎を介して高層側基礎に確実に伝達して高層側基礎の側で確実に負担することができる。 Further, according to this configuration, horizontal force transmission avoidance means interposed between the low-layer foundation and the lower-layer-side foundation support section below the low-layer-side foundation prevents transmission of horizontal force from the low-layer side foundation to the low-layer side foundation support section. Since this is avoided, the horizontal load acting on the low-rise side building can be reliably transmitted to the high-rise side foundation via the low-rise side foundation, so that the high-rise side foundation can bear the load.

本発明の第２特徴構成は、前記低層側基礎支持部が、前記低層側基礎の下方の地盤に分散状態で埋設される多数本の杭にて構成され、
前記低層側基礎の下方の地盤において、前記高層側建物とは反対側の端部には前記杭が配置され、且つ、前記高層側建物の側の端部には前記杭が配置されておらず、その杭が配置されていない前記高層側建物の側の端部において前記低層側建物の一部の鉛直荷重を前記低層側基礎と一体化された前記高層側基礎の側にて負担するように構成されている点にある。 In a second characteristic configuration of the present invention, the low-layer side foundation support portion is composed of a large number of piles buried in the ground below the low-layer side foundation in a dispersed state,
In the ground below the low-rise side foundation, the pile is arranged at the end opposite to the high-rise side building, and the pile is not arranged at the end on the side of the high-rise side building. , so that the high-rise side foundation integrated with the low-rise side foundation bears the vertical load of a part of the low-rise side building at the end of the high-rise side building where the pile is not arranged. It is in the point that it is configured.

本構成によれば、前記低層側建物の一部の鉛直荷重を前記高層側基礎の側に負担させる形態で、高層側建物の近傍の杭を省略することができ、更なるコストダウンや省人化を図ることができる。 According to this configuration, the piles in the vicinity of the high-rise side building can be omitted in a form in which the vertical load of a part of the low-rise side building is borne by the high-rise side foundation side, and further cost reduction and labor saving can be achieved. can be improved.

本発明の第３特徴構成は、前記高層側基礎の設置深さが前記低層側基礎の設置深さよりも深く、
設置深さが深い側の前記高層側基礎における前記低層側基礎の側の端部を、設置深さが浅い側の前記低層側基礎における前記高層側基礎の側の端部の直下まで水平方向に延長し、その延長した前記高層側基礎における前記低層側基礎の側の端部と前記低層側基礎における前記高層側基礎の側の端部とを鉛直姿勢の鉄筋コンクリート構造の基礎接続部位にて接続している点にある。
本発明の第４特徴構成は、前記高層側基礎が直接基礎として構成され、前記低層側基礎が、それの下方の地盤に埋設される杭にて前記低層側基礎支持部が構成された杭基礎として構成されている点にある。 A third characteristic configuration of the present invention is that the installation depth of the high-rise side foundation is deeper than the installation depth of the low-rise side foundation,
The end of the high-rise side foundation on the side with a deeper installation depth on the low-side foundation side extends horizontally to directly below the end on the high-rise side foundation side of the low-layer side foundation on the side with a shallow installation depth. and connecting the end of the extended high-rise side foundation on the low-rise side foundation side and the end of the low-rise side foundation on the high-rise side foundation side at a foundation connection portion of the reinforced concrete structure in a vertical posture. at the point.
A fourth characteristic configuration of the present invention is a pile foundation in which the high-rise side foundation is configured as a direct foundation, and the low-layer side foundation is composed of piles buried in the ground below the low-layer side foundation support portion. The point is that it is configured as

本構成によれば、杭基礎として構成された低層側基礎に伝達される水平荷重を、杭基礎で負担せず、直接基礎として構成された高層側基礎の側で負担するので、水平荷重を考慮せずに杭基礎における杭の仕様を設定することができ、更なるコストダウンや省人化を図ることができる。 According to this configuration, the horizontal load transmitted to the low-rise side foundation constructed as a pile foundation is not borne by the pile foundation, but is borne by the high-rise side foundation constructed as a direct foundation, so the horizontal load is taken into account. It is possible to set the specifications of the piles in the pile foundation without having to do so, and it is possible to achieve further cost reduction and labor saving.

本発明の建築物の基礎構造の実施形態を図面に基づいて説明する。
この基礎構造は、図１に示すように、高層側建物１を支持する高層側基礎１０と、高層側建物１に隣接する低層側建物２を支持する低層側基礎２０とを有する。高層側基礎１０及び低層側基礎２０は、鉄筋コンクリート造の基礎として構成されている。 An embodiment of the foundation structure of a building according to the present invention will be described with reference to the drawings.
This foundation structure has, as shown in FIG. The high-rise side foundation 10 and the low-rise side foundation 20 are configured as reinforced concrete foundations.

図１に示す例では、高層側建物１は、柱１Ａや梁１Ｂ等の躯体が鉄筋コンクリートにて構成された鉄筋コンクリート造の高層建物として構成され、免震装置１Ｃ（図２参照）を介して高層側基礎１０に支持されている。低層側建物２は、柱２Ａや梁２Ｂ等の躯体が鉄骨にて構成された鉄骨造の低層建物として構成され、免震装置１Ｃを介さずに直接的に低層側基礎２０に支持されている。高層側建物１の重量は、低層側建物２の重量よりも遥かに大きく、高層側建物１の単位面積当たりの重量（例えばｔ／ｍ２）も、低層側建物２の単位面積当たりの重量よりも遥かに大きくなっている。 In the example shown in FIG. 1, the high-rise side building 1 is configured as a reinforced concrete high-rise building in which the framework such as columns 1A and beams 1B is made of reinforced concrete. It is supported by the side foundation 10. The low-rise side building 2 is configured as a steel-framed low-rise building in which the framework such as the columns 2A and the beams 2B is made of steel, and is directly supported by the low-rise side foundation 20 without the seismic isolation device 1C. . The weight of the high-rise side building 1 is much larger than the weight of the low-rise side building 2, and the weight per unit area of the high-rise side building 1 (for example, t/m2) is also greater than the weight per unit area of the low-rise side building 2. It's getting much bigger.

なお、高層側建物１及び低層側建物２は、鉄骨造や鉄筋コンクリート造、鉄骨鉄筋コンクリート造、それらの二種以上を複合させた複合構造等の各種の構造を適宜に採用することができ、また、免震構造や耐震構造、制振構造等も適宜に採用することができる。 For the high-rise side building 1 and the low-rise side building 2, various structures such as a steel-framed structure, a reinforced concrete structure, a steel-framed reinforced concrete structure, and a composite structure combining two or more of these structures can be appropriately adopted. A seismic isolation structure, an earthquake-resistant structure, a damping structure, etc. can also be appropriately adopted.

図２に示すように、高層側基礎１０は、地盤３中において比較的支持層に近い深さ位置に耐圧版等が設置され、高層側建物１の荷重を直接的に支持層に伝達する直接基礎として構成されている。高層側基礎１０が設置される設置面には、その表層のみを改良した浅層地盤改良４が施されている。本実施形態では、高層側基礎１０は、直接基礎の一例として、直接基礎としての支持能力を生かしながら必要最小限の摩擦杭５が併用されたパイルド・ラフト基礎と呼ばれる基礎形式を採用しており、高層側基礎１０の下方の設置面に必要最小限の摩擦杭５が建て込まれている。なお、高層側基礎１０の端部（図中左側の端部）には、免震ピットの側壁を構成する擁壁８が一体化されている。 As shown in FIG. 2, the high-rise side foundation 10 has a pressure plate or the like installed at a depth position relatively close to the support layer in the ground 3, and directly transmits the load of the high-rise side building 1 to the support layer. constructed as a basis. The installation surface on which the high-rise side foundation 10 is installed is provided with a shallow layer ground improvement 4 for improving only the surface layer. In this embodiment, the high-rise side foundation 10 employs a foundation form called piled raft foundation, as an example of a direct foundation, in which the minimum necessary friction piles 5 are used while taking advantage of the support capacity of a direct foundation. , a necessary minimum number of friction piles 5 are built in the installation surface below the high-rise side foundation 10. - 特許庁A retaining wall 8 forming a side wall of the seismic isolation pit is integrated with the edge of the high-rise side foundation 10 (the edge on the left side in the drawing).

低層側基礎２０は、地盤３中において高層側基礎１０よりも浅い深さ位置に耐圧版等が設置され、その下方の設置面に支持層まで延びる状態で建て込まれた低層側基礎支持部としての多数の支持杭６（杭の一例）を介して低層側基礎２０の荷重を支持層に伝達する杭基礎として構成されている。本実施形態では、多数の支持杭６は、柱状に地盤３を改良して構成された柱状地盤改良杭として、低層側基礎２０の下方の地盤３に分散状態で埋設されている。 The low-layer side foundation 20 is a low-layer side foundation support portion built in a state where a pressure plate or the like is installed in the ground 3 at a depth position shallower than the high-rise side foundation 10 and extends to the support layer on the installation surface below it. It is configured as a pile foundation that transmits the load of the lower layer side foundation 20 to the support layer via a large number of support piles 6 (an example of piles). In this embodiment, a large number of supporting piles 6 are embedded in the ground 3 below the low-rise side foundation 20 in a dispersed state as columnar ground improvement piles configured by improving the ground 3 in a columnar shape.

そして、この基礎構造では、高層側基礎１０と低層側基礎２０とが水平荷重を伝達可能なように一体化され、低層側建物２に作用する水平荷重を、低層側基礎２０を介して高層側基礎１０に伝達して低層側基礎２０の側で負担せずに高層側基礎１０の側で負担するように構成されている。 In this foundation structure, the high-rise side foundation 10 and the low-rise side foundation 20 are integrated so as to be able to transmit the horizontal load, and the horizontal load acting on the low-rise side building 2 is transferred to the high-rise side via the low-rise side foundation 20. The load is transmitted to the foundation 10 so that the high-rise side foundation 10 side bears the load instead of the low-rise side foundation 20 side.

具体的には、設置深さが深い側の高層側基礎１０の端部（図中右側の端部）を、設置深さが浅い側の低層側基礎２０の端部（図中左側の端部）の直下まで延長し、その延長した高層側基礎１０の端部と低層側基礎２０の端部とを鉛直姿勢の鉄筋コンクリート造の基礎接続部位３０にて接続している。この基礎接続部位３０は、免震ピットの側壁を構成しており、免震ピット内へ地下水の浸入を防止する役割も果たしている。基礎接続部位３０は、例えば、高層側基礎１０や低層側基礎２０と同等又はそれ以上の剛性を有するように、その厚みやコンクリート量、鉄筋量等を設定することができる。 Specifically, the end of the high-rise side foundation 10 on the side with the deeper installation depth (the right end in the drawing) is replaced with the end of the low-layer side foundation 20 on the side with the shallower installation depth (the left end in the drawing). ), and the extended end of the high-rise side foundation 10 and the end of the low-rise side foundation 20 are connected at a foundation connection portion 30 made of reinforced concrete in a vertical posture. The foundation connecting portion 30 constitutes the side wall of the seismic isolation pit, and also serves to prevent groundwater from entering the seismic isolation pit. The thickness, the amount of concrete, the amount of reinforcing bars, etc., of the foundation connecting portion 30 can be set so as to have rigidity equal to or greater than that of the high-rise side foundation 10 or the low-rise side foundation 20, for example.

この基礎接続部位３０により、高層側基礎１０と低層側基礎２０とが一体的に接続されて、低層側建物２に作用する水平荷重を低層側基礎２０から高層側基礎１０に伝達して高層側基礎１０の側にて負担するように構成されている。 The high-rise side foundation 10 and the low-rise side foundation 20 are integrally connected by the foundation connection portion 30, and the horizontal load acting on the low-rise side building 2 is transmitted from the low-rise side foundation 20 to the high-rise side foundation 10, thereby It is configured to bear on the side of the foundation 10 .

また、低層側基礎２０の下方の設置面に埋設される多数本の支持杭６のうち、図２中に仮想線（一点鎖線）で示される高層側建物１の近傍の支持杭６が省略されている。よって、その省略された支持杭６が負担すべき低層側建物２の一部の鉛直荷重を、低層側建物２の端部（図中左側の端部）の直下に配置された上述の基礎接続部位３０により、低層側基礎２０から高層側基礎１０に伝達し、高層側基礎１０の側にて負担するように構成されている。 Further, among the many supporting piles 6 embedded in the installation surface below the low-rise side foundation 20, the supporting piles 6 near the high-rise side building 1 indicated by the imaginary line (one-dot chain line) in FIG. 2 are omitted. ing. Therefore, the vertical load of the part of the low-rise building 2 that should be borne by the omitted support pile 6 is transferred to the above-mentioned foundation connection arranged directly below the end of the low-rise building 2 (the end on the left side in the figure). The part 30 is configured to transmit from the low-rise side foundation 20 to the high-rise side foundation 10 and to bear the load on the high-rise side foundation 10 side.

更に、低層側基礎２０とその下方の支持杭６との間には、水平力の伝達を回避するための水平力伝達回避手段としての敷砂利７が介在されている。この敷砂利７により、低層側基礎２０から支持杭６への水平力の伝達が回避される。よって、低層側建物２に作用する水平荷重を、低層側基礎２０を介して高層側基礎１０に確実に伝達して高層側基礎１０の側で確実に負担することができる。
なお、水平力伝達回避手段としては、敷砂利７に限らず、滑り材やエラストマ等の低層側基礎２０と低層側基礎支持部との間で水平力の伝達を回避可能な各種の構成を採用することができる。 Further, gravel 7 is interposed between the low-rise side foundation 20 and the supporting piles 6 therebelow as horizontal force transmission avoiding means for avoiding the transmission of horizontal force. This gravel 7 prevents transmission of horizontal force from the lower foundation 20 to the support piles 6 . Therefore, the horizontal load acting on the low-rise side building 2 can be reliably transmitted to the high-rise side foundation 10 via the low-rise side foundation 20, and the high-rise side foundation 10 side can surely bear the load.
The means for avoiding transmission of horizontal force is not limited to the gravel 7, but employs various configurations such as slip materials and elastomers that can avoid the transmission of horizontal force between the low-rise side foundation 20 and the low-rise side foundation support portion. can do.

このように構成された基礎構造を構築する際には、先ずは、高層側基礎１０と低層側基礎２０とを図２中に点線で示される後施工部位としての後打ち帯９を残して構築する。その後、高層側基礎１０の上に高層側建物１を構築するのに伴い高層側基礎１０が所定レベルまで沈下した時点で、後打ち帯９を構築して高層側基礎１０と低層側基礎２０とを一体化する。
このようにすれば、低層側基礎２０が、高層側基礎１０に引き連れられて沈下して下方の支持杭６に押し付けられることで、低層側基礎２０と支持杭６との間で水平力が伝達され易くなったり、低層側基礎２０と高層側基礎１０との間に応力が残留したりするのを抑制することができる。 When constructing the foundation structure configured in this way, first, the high-rise side foundation 10 and the low-rise side foundation 20 are constructed while leaving the post-strike band 9 as a post-construction portion indicated by a dotted line in FIG. do. After that, when the high-rise building 1 is constructed on the high-rise foundation 10 and the high-rise foundation 10 settles down to a predetermined level, the post-strike zone 9 is constructed to form the high-rise foundation 10 and the low-rise foundation 20. unify.
In this way, the low-layer side foundation 20 sinks along with the high-rise side foundation 10 and is pressed against the supporting piles 6 below, whereby horizontal force is transmitted between the low-layer side foundation 20 and the supporting piles 6. It is possible to prevent stress from remaining between the low-layer-side foundation 20 and the high-rise-side foundation 10 .
