Description

本発明は、構造物の基礎構造に関する。   The present invention relates to a basic structure of a structure.

従来より、病院のような水廻り機能を多数備える構造物や大容量の雨水貯留装置を必要とする構造物、また屋内に駐車場を有する構造物等には、例えば、特許文献1に示すように、上部構造体の直下に位置する領域に二重ピットを構築し、該二重ピット内に各々構造物毎で水廻り機能や通気機能、雨水貯水槽等の必要な設備を設置する場合が多い。
該二重ピットは、一般に、上部構造体の床スラブと基礎床版との間に形成され、前記上部構造体の柱脚部どうしを架け渡すように配置された地中梁の梁成を調整することにより、二重ピットとして必要な有効高さを確保している。
特開平8−320142号公報(図1参照)
Conventionally, as shown in Patent Document 1, for example, a structure having a lot of watering functions such as a hospital, a structure that requires a large-capacity rainwater storage device, a structure having a parking lot indoors, etc. In addition, there is a case where a double pit is constructed in an area located directly under the upper structure, and necessary facilities such as a water function, a ventilation function, and a rainwater storage tank are installed for each structure in the double pit. Many.
The double pit is generally formed between the floor slab of the superstructure and the foundation floor slab, and adjusts the beam formation of the underground beam arranged so as to bridge the column bases of the superstructure. By doing so, the effective height required as a double pit is secured.
JP-A-8-320142 (see FIG. 1)

このような二重ピットは、スパン毎で前記地中梁によって空間が分割される構成となるから、二重ピット内のメンテナンスを考慮すると、分割された全ての空間に作業員の出入りを可能とするための人通孔を構築する必要がある。このため、人通孔として地中梁に作業員が通過できる程度の貫通孔を設ける方法や、地中梁の下にトンネルを築造する方法等が採用されている。   Since such double pits are configured such that the space is divided by the underground beam for each span, it is possible to allow workers to enter and leave all the divided spaces in consideration of maintenance in the double pits. It is necessary to build a human passage to do this. For this reason, a method of providing a through hole that allows a worker to pass through the underground beam as a through hole, a method of constructing a tunnel under the underground beam, and the like are adopted.

しかし、上述するような地中梁に貫通孔を設ける構成は、地中梁の貫通孔を形成する位置に梁貫通補強筋を配置する必要があり、地中梁の構築が煩雑になるとともに工費が増大する。また、構造条件上は地中梁の梁成を小さくできるにもかかわらず、二重ピットとしての有効高さや貫通孔に人通孔としての有効高さを確保するために梁成を大きく取る等の無駄が生じていた。
一方、地中梁の下にトンネルを設ける構成では、トンネルの築造が煩雑で工費の増大及び工期の長期化を招くだけでなく、トンネル内に水がたまりやすいことからトンネル自身のメンテナンスも必要となる等、様々な課題を生じている。
However, in the configuration in which the through-hole is provided in the underground beam as described above, it is necessary to arrange a beam penetration reinforcing bar at a position where the through-hole of the underground beam is to be formed. Will increase. In addition, despite the fact that the beam formation of the underground beam can be reduced due to the structural conditions, the beam formation is increased to ensure the effective height as a double pit and the effective height as a through hole in the through hole, etc. Wasted.
On the other hand, in the configuration in which the tunnel is provided under the underground beam, the construction of the tunnel is complicated and not only increases the construction cost and lengthens the construction period, but also requires maintenance of the tunnel itself because water tends to accumulate in the tunnel. Various issues have arisen, such as.

上記事情に鑑み、本発明は、簡略な構成で作業性がよく、またメンテナンス時における作業員の出入りを可能とする人通孔を備えた二重ピットを有する構造物の基礎構造を提供することを目的としている。   In view of the above circumstances, the present invention provides a basic structure of a structure having a double pit provided with a through hole that allows a worker to enter and exit during maintenance with a simple configuration and good workability. It is an object.

請求項1記載の構造物の基礎構造は、柱と床スラブを備える上部構造体を支持する杭基礎と、該杭基礎を構成する複数の杭体各々に接合している前記柱の隣り合う脚部どうしに架け渡す地中梁を備え、前記地中梁の直上に位置する前記床スラブと前記地中梁とにより囲われる領域に、二重ピットを有する構造物の基礎構造であって、前記柱が、上部構造体の外周縁に沿うよう配置される複数の外周柱と、上部構造体の内方に位置する複数の内部柱を備えるとともに、前記地中梁が、隣り合う外周柱の脚部どうしに架け渡される外周梁と、隣り合う内部柱の脚部どうし及び隣り合う内部柱と外周柱の脚部どうしに架け渡される内部梁とにより構成され、前記内部梁は、前記外周梁と比較して梁成が小さく、上端面が前記外周梁と同一水平レベルに位置し、前記内部梁の下端面と、前記杭体頭部近傍と同様の水平レベルに位置する基礎底面に打設された捨てコンクリートとの間に梁下空間が形成され、前記内部梁により分割された前記二重ピットの複数の領域が連通していることを特徴としている。 The foundation structure of the structure according to claim 1 is a pile foundation that supports an upper structure including a column and a floor slab, and adjacent legs of the columns that are joined to each of a plurality of pile bodies that constitute the pile foundation. A foundation structure of a structure having a double pit in a region surrounded by the floor slab and the underground beam located directly above the underground beam. The column includes a plurality of outer peripheral columns arranged along the outer peripheral edge of the upper structure and a plurality of inner columns positioned inward of the upper structure, and the underground beam is a leg of an adjacent outer column. An outer peripheral beam spanned between the parts, and the legs of adjacent internal columns, and an inner beam spanned between the adjacent internal columns and the legs of the outer peripheral column, and the inner beam is connected to the outer peripheral beam Compared with small beam formation, upper end surface is at the same horizontal level as the outer peripheral beam Position, and the lower end surface of the inner beams, beams under the space between the Da設been abandoned concrete foundation bottom located horizontal level as in the vicinity of the pile body head is formed, divided by the inner beams A plurality of areas of the double pits communicated with each other.

請求項2記載の構造物の基礎構造は、前記内部梁の外周柱との当接端部に、垂直ハンチが設けられることを特徴としている。   The basic structure of the structure according to claim 2 is characterized in that a vertical haunch is provided at a contact end portion of the inner beam with the outer peripheral column.

請求項1記載の構造物の基礎構造によれば、前記外周梁の梁成は前記二重ピットに必要な有効高さに応じて決定されるものの、二重ピット内に位置する内部梁の梁成は、構造条件に応じた梁成に設定できるため、二重ピットを有する構造物の基礎構造を合理的な構成とすることが可能となる。   According to the basic structure of the structure according to claim 1, although the beam formation of the outer peripheral beam is determined according to the effective height necessary for the double pit, the beam of the internal beam located in the double pit Since the composition can be set to a beam composition according to the structural conditions, it becomes possible to make the foundation structure of the structure having double pits rational.

また、外周梁と比較して内部梁の梁成が小さく、両者の上端面は同一水平レベルに配置されることから、内部梁の下端面と基礎底面との間に梁下空間が形成されるため、内部梁により分割された二重ピットの複数の領域は連通される。したがって、外周梁と内部梁の梁成に、メンテナンス時における作業員の出入りを可能とする高さと同程度の差異を設けておくことにより、これを人通孔として利活用することが可能となる。
これに伴い、人通孔を備えるための新たな構成の付加を不要とできるため、従来より地中梁に設けていた貫通孔を形成するための梁貫通補強筋の配設も不要となり、工費削減、工期短縮に大きく寄与することが可能となる。
また、人通孔によることなく、二重ピットに必要な有効高さに応じた地盤掘削を実施すればよいため、生産効率が良く、工費削減及び工期短縮に大きく寄与することが可能となる。
In addition, the beam formation of the internal beam is small compared to the outer peripheral beam, and the upper end surfaces of both are arranged at the same horizontal level, so a space under the beam is formed between the lower end surface of the internal beam and the bottom surface of the foundation. Therefore, a plurality of areas of the double pit divided by the internal beam are communicated. Therefore, if the difference between the height of the outer beam and the inner beam is the same as the height that allows workers to enter and exit during maintenance, this can be used as a through hole. .
As a result, it is not necessary to add a new configuration for providing a through hole, so that it is no longer necessary to provide a beam penetration reinforcing bar for forming a through hole that has been provided in the underground beam. It is possible to greatly contribute to the reduction and shortening of the construction period.
In addition, ground excavation according to the effective height required for the double pits can be performed without using a through hole, so that the production efficiency is good and it is possible to greatly contribute to the reduction of construction cost and construction period.

さらに、前記梁下空間は、人通孔として利用できるだけでなく、設備配管ルートに利用できるものであり、梁下空間に設備配管を通した場合、梁貫通補強が不要で設備配管のピッチ・位置に制限がないため、コストダウン・生産性の向上を図ることが可能となる。   Furthermore, the space under the beam can be used not only as a through hole, but also as a facility piping route. When the facility piping is passed through the space below the beam, beam penetration reinforcement is not required and the pitch / position of the facility piping is not required. Therefore, it is possible to reduce costs and improve productivity.

請求項2に記載の構造物の基礎構造によれば、前記内部梁は、外周柱と当接する端部に垂直ハンチを備えることから、内部梁と外周柱との取り合い部に大きな応力が生じた場合にも破損することは無く、安全な基礎構造を提供することが可能となる。   According to the basic structure of the structure according to claim 2, the internal beam includes a vertical hunch at an end portion that abuts the outer peripheral column, and thus a large stress is generated in a joint portion between the inner beam and the outer peripheral column. In some cases, it is not damaged, and a safe foundation structure can be provided.

本発明の構造物の基礎構造を図1から図3に示す。本発明は、杭基礎と地中梁を備える構造物の基礎構造であって、杭基礎に支持される上部構造体の柱の隣り合う脚部どうしに架け渡される地中梁と、該地中梁の直上に位置する上部構造体の床スラブにより囲われる領域に二重ピットを構成するとともに、前記地中梁のうち構造物の外周縁に沿って配置される外周梁と比較して、構造物の内領域に配置される内部梁の梁成を小さく取ることにより、内部梁の下端面と基礎底面との間に空間を形成し、これを人通孔として利用するものである。   The basic structure of the structure of the present invention is shown in FIGS. The present invention provides a foundation structure of a structure including a pile foundation and an underground beam, the underground beam spanning between adjacent legs of a column of an upper structure supported by the pile foundation, and the underground A double pit is formed in the region surrounded by the floor slab of the upper structure located immediately above the beam, and the structure is compared with the outer peripheral beam arranged along the outer peripheral edge of the structure among the underground beams. A space is formed between the lower end surface of the inner beam and the bottom surface of the foundation by using a small beam of the inner beam arranged in the inner region of the object, and this is used as a through hole.

図1に示すように、構造物1は、複数の柱3と床スラブ2aを備える上部構造体2と、これを支持する基礎構造6により構成されており、該基礎構造6は、杭基礎7と地中梁9とを備えている。
該杭基礎7は、図示しない地盤中の支持層に杭先端を支持された状態で鉛直状に立設された複数の杭体8により構成されており、該杭体8は、上部構造体2の外周縁に沿うように所定の離間間隔をもって複数配置されているとともに、上部構造体2の内領域にも同じ離間間隔をもって複数が配置されている。
本実施の形態において、杭体8には場所打ちコンクリート杭を用いているが、必ずしもこれにこだわるものではなく、上部構造体2を支持できる構成であれば鋼管杭やPC杭等何れの種類の杭を用いても良い。
As shown in FIG. 1, the structure 1 is comprised by the upper structure 2 provided with the some pillar 3 and the floor slab 2a, and the foundation structure 6 which supports this, The foundation structure 6 is the pile foundation 7 And an underground beam 9.
The pile foundation 7 is composed of a plurality of pile bodies 8 erected vertically with the pile tip supported by a support layer in the ground (not shown). The pile body 8 is composed of the upper structure 2. A plurality are arranged with a predetermined spacing interval along the outer peripheral edge of the upper structure 2 and a plurality are also arranged with the same spacing interval in the inner region of the upper structure 2.
In the present embodiment, a cast-in-place concrete pile is used as the pile body 8, but this is not necessarily limited to this, and any type of steel pipe pile, PC pile, or the like can be used as long as the upper structure 2 can be supported. Pile may be used.

該杭基礎7を構成する複数の杭体8各々の頭部には、前記上部構造体2を構成する柱3が杭体8と鉛直方向で同軸状に配置されており、柱脚部と杭頭部とをコンクリート14で根巻きされることにより両者は剛に接合されている。なお、該柱3のうち上部構造体2の外周縁に沿うように配置されている前記外周柱4は、前記杭体8と鉛直方向に同軸ではなく偏心させた状態でコンクリート14に根巻きされ剛に接合されている。   At the head of each of the plurality of pile bodies 8 constituting the pile foundation 7, the pillar 3 constituting the upper structure 2 is arranged coaxially with the pile body 8 in the vertical direction. The head is rooted with concrete 14 so that both are rigidly joined. In addition, the said outer periphery pillar 4 arrange | positioned so that the outer periphery of the upper structure 2 among the pillars 3 may be rooted around the concrete 14 in the state eccentrically not coaxially with the said pile body 8 in the perpendicular direction. It is rigidly joined.

また、前記地中梁9は、隣り合う前記柱3の脚部どうしを架け渡すように水平に配置されている。該地中梁9は、図2に示すように、隣り合う外周柱4の脚部どうしを連結する外周梁10、前記柱3のうち上部構造体2の内領域に配置されている隣り合う内部柱5どうしまたは隣り合う内部柱5と外周柱4の脚部どうしを連結する内部梁11により構成されている。つまり、前記外周梁10は、図2に示すように、平面視で前記構造物1の構築領域を囲うように配置されており、前記内部梁11は、平面視で前記外周梁10に囲われた構造物1の内領域を複数に分割するように配置されることとなる。   The underground beam 9 is horizontally disposed so as to bridge the legs of the adjacent pillars 3. As shown in FIG. 2, the underground beam 9 includes an outer peripheral beam 10 that connects the legs of adjacent outer peripheral columns 4, and an adjacent inner portion disposed in an inner region of the upper structure 2 among the columns 3. It is comprised by the internal beam 11 which connects the pillars 5 or the leg part of the adjacent internal pillar 5 and the outer periphery pillar 4 mutually. That is, as shown in FIG. 2, the outer peripheral beam 10 is arranged so as to surround the construction region of the structure 1 in a plan view, and the inner beam 11 is surrounded by the outer peripheral beam 10 in a plan view. The inner region of the structure 1 is arranged so as to be divided into a plurality of parts.

ところで、前記内部梁11は、図1に示すように、梁成が外周梁10と比較して小さく形成されており、また、上端面が前記外周梁10と同一水平レベルとなる高さ位置に配置されている。なお、該内部梁11の梁成は、前記外周梁10と比較して小さく、かつ少なくとも構造条件を満たす高さを確保していれば、何れの大きさに成形しても良い。
また、該内部梁11の前記外周柱4と当接する端部には、垂直ハンチ11aが設けられている。これは、前記外周柱4と内部梁11との取り合い部に大きな応力が生じやすいことを考慮したものであり、その高さは構造条件を満たすよう形成されている。
Incidentally, as shown in FIG. 1, the inner beam 11 has a beam formed smaller than the outer beam 10, and the upper end surface is at a height position where it is at the same horizontal level as the outer beam 10. Has been placed. The inner beam 11 may be formed in any size as long as the beam is smaller than the outer beam 10 and at least a height that satisfies the structural conditions is secured.
A vertical hunch 11 a is provided at the end of the inner beam 11 that contacts the outer peripheral column 4. This is because it is considered that a large stress is likely to be generated in the joint portion between the outer peripheral column 4 and the internal beam 11, and the height thereof is formed so as to satisfy the structural condition.

このような構成よりなる構造物1は、前記上部構造体2に床スラブ2aが備えられているとともに、基礎構造6を構成する地中梁9の梁下で、前記杭体の頭部近傍と同様の水平レベルに位置する基礎底面には捨てコンクリート13が打設されている。これにより、構造物1の基礎構造6には、前記外周梁10、地中梁9の直上に位置する床スラブ2a、及び梁下に位置する捨てコンクリート13により囲まれた空間に、図3に示すように、二重ピット12が形成されることとなる。   The structure 1 having such a structure is provided with a floor slab 2a in the upper structure 2 and under the beam of the underground beam 9 constituting the foundation structure 6, and near the head of the pile body. Abandoned concrete 13 is placed on the bottom surface of the foundation located at the same horizontal level. As a result, in the foundation structure 6 of the structure 1, the space surrounded by the outer peripheral beam 10, the floor slab 2a located directly above the underground beam 9, and the discarded concrete 13 located below the beam is shown in FIG. As shown, double pits 12 will be formed.

該二重ピット12は、図3に示すように、前記内部梁11によりスパン毎でその領域を複数に分割されるものの、前述したように、内部梁11がその梁成を外周梁10と比較して小さく形成され、また上端面を前記外周梁10と同一水平レベルとなるように配置されている。つまり、該内部梁11の下端面と捨てコンクリート13との間に梁下空間11bが形成されており、これらは連通している。
したがって、該梁下空間11bに作業員が通過できる程度の有効高さを確保することにより、これを人通孔として利用することができるものである。
As shown in FIG. 3, the double pit 12 is divided into a plurality of areas for each span by the internal beam 11, but as described above, the internal beam 11 compares the beam formation with the outer beam 10. The upper end surface is arranged to be at the same horizontal level as the outer peripheral beam 10. That is, the under-beam space 11b is formed between the lower end surface of the internal beam 11 and the discarded concrete 13, and these spaces communicate with each other.
Therefore, by ensuring an effective height that allows an operator to pass through the under-beam space 11b, this can be used as a through hole.

なお、該梁下空間11bは、前記外周梁10と内部梁11との梁成の差異により形成されるものであるから、梁下空間11bを人通孔として利用する場合にはこの差異を作業員が通過できる程度の高さに調整すればよい。
また、前記二重ピット12自身の有効高さは、外周梁10の梁成を調整することにより必要高さを確保できるものである。
The under-beam space 11b is formed by the difference in beam formation between the outer beam 10 and the inner beam 11, and this difference is used when the under-beam space 11b is used as a through hole. The height may be adjusted so that a member can pass through.
Further, the effective height of the double pit 12 itself can be secured by adjusting the beam formation of the outer peripheral beam 10.

上述する構成によれば、前記構造物1の基礎構造6は、前記外周梁10の梁成が前記二重ピット12に必要な有効高さに応じて決定されるものの、二重ピット12内に位置する内部梁11の梁成は、構造条件に応じた梁成に設定できるため、二重ピット12を有する構造物1の基礎構造6を合理的な構成とすることが可能となる。   According to the above-described configuration, the foundation structure 6 of the structure 1 is formed in the double pit 12 although the beam formation of the outer peripheral beam 10 is determined according to the effective height required for the double pit 12. Since the beam formation of the positioned internal beam 11 can be set to a beam formation according to the structural condition, it becomes possible to make the foundation structure 6 of the structure 1 having the double pits 12 rational.

また、外周梁10と比較して内部梁11の梁成が小さく、両者の上端面は同一水平レベルに配置されることから、内部梁11の下端面と基礎底面に打設された捨てコンクリート13との間に梁下空間11bが形成されるため、内部梁11により分割された二重ピットの複数の領域は連通される。したがって、外周梁10と内部梁11の梁成に、メンテナンス時における作業員の出入りを可能とする高さと同程度の差異を設けておくことにより、これを人通孔として利活用することが可能となる。   Further, since the beam formation of the inner beam 11 is smaller than that of the outer beam 10 and the upper end surfaces of both are arranged at the same horizontal level, the discarded concrete 13 placed on the lower end surface and the foundation bottom surface of the inner beam 11 is disposed. Since a space 11b below the beam is formed between the two, a plurality of regions of the double pit divided by the internal beam 11 are communicated. Therefore, by providing a difference between the outer beam 10 and the inner beam 11 at the same level as the height at which workers can enter and exit during maintenance, this can be used as a through hole. It becomes.

これに伴い、人通孔を備えるための新たな構成の付加を不要とできるため、従来より地中梁9に設けていた貫通孔を形成するための梁貫通補強筋の配設も不要となり、工費削減、工期短縮に大きく寄与することが可能となる。
また、人通孔によることなく、二重ピット12に必要な有効高さに応じた地盤掘削を実施すればよいため、生産効率が良く、工費削減及び工期短縮に大きく寄与することが可能となる。
Along with this, it is not necessary to add a new configuration for providing a through hole, so it is also unnecessary to provide a beam penetration reinforcing bar for forming a through hole that has been provided in the underground beam 9 conventionally. It is possible to greatly contribute to the reduction of construction cost and construction period.
Moreover, since ground excavation according to the effective height required for the double pit 12 may be performed without using a through hole, the production efficiency is good, and it is possible to greatly contribute to the reduction of the construction cost and the construction period. .

さらに、前記梁下空間11bは、人通孔として利用できるだけでなく、設備配管ルートに利用できるものであり、該梁下空間11bに設備配管を通した場合、梁貫通補強が不要で設備配管のピッチ・位置に制限がないため、コストダウン・生産性の向上を図ることが可能となる。   Further, the space under the beam 11b can be used not only as a through hole but also as a facility piping route. When the facility piping is passed through the beam under space 11b, the beam penetration reinforcement is not required. Since there is no restriction on the pitch and position, it is possible to reduce costs and improve productivity.

さらに、前記内部梁11は、外周柱4と当接する端部に垂直ハンチ11aを備えることから、内部梁11と外周梁10との取り合い部に大きな応力が生じた場合にも破損することは無く、安全な基礎構造を提供することが可能となる。   Furthermore, since the internal beam 11 includes the vertical hunch 11a at the end that comes into contact with the outer peripheral column 4, the inner beam 11 is not damaged even when a large stress occurs in the joint portion between the inner beam 11 and the outer peripheral beam 10. It is possible to provide a safe foundation structure.
