前方の競技場側から後方に向けて上る方向に傾斜して観客席が上面に設けられた床部を備えた建築物は、通常、一体的に構築された一の構造物に床部全体が設けられている（例えば、特許文献１を参照。）。また、特許文献１に記載の建築物では、床部全体を設けた一の構造物が杭基礎により支持されている。 A building with a floor that slopes upwards from the stadium side in front and has spectator seats on the upper surface is usually a single integrally constructed structure that has the entire floor. provided (see, for example, Patent Literature 1). Further, in the building described in Patent Literature 1, one structure provided with the entire floor is supported by a pile foundation.

特開２０１５－２２９８８１号公報JP 2015-229881 A

上記特許文献１に記載の建築物では、比較的広い地盤上に床部全体を設けた構造物が構築されることになる。よって、その構造物を支持するための杭基礎を比較的広範囲に設ける必要があり、高コスト化や工期の長期化等の問題が生じる。また、床部全体を設けた構造物は、床部の前方に向かう下り傾斜が略地盤高さに至るまで続くような不整形なものとなる。このことで、構造物の構造設計が煩雑なものとなる上に、それを構築するのに必要な工期の長期化が懸念される。
この実情に鑑み、本発明の主たる課題は、前方の競技場側から後方に向けて上る方向に傾斜して観客席が上面に設けられた床部を備えた建築物において、構造設計の簡素化及び工期短縮を実現可能な技術を提供する点にある。 In the building described in Patent Literature 1, a structure is constructed in which the entire floor is provided on a relatively wide ground. Therefore, it is necessary to provide a relatively wide range of pile foundations to support the structure, which causes problems such as high cost and long construction period. In addition, the structure having the entire floor becomes irregular in shape, such that the downward slope of the floor toward the front continues up to approximately the ground level. As a result, the structural design of the structure becomes complicated, and there is concern that the construction period required for constructing the structure will be prolonged.
In view of this situation, the main object of the present invention is to simplify the structural design of a building that has a floor that slopes upward from the stadium side in front and has spectator seats on the upper surface. And it is to provide a technology that can shorten the construction period.

本発明の第１特徴構成は、前方の競技場側から後方に向けて上る方向に傾斜して観客席が上面に設けられた床部を備えた建築物であって、
前記床部として、最前部分に位置する最前床部と、当該最前床部以外の主床部と、を備え、
前記最前床部を有する最前構造物が、前記主床部を有する主構造物から分離されて構築され、
前記最前床部と前記主床部とを連設させる連設部を備え、
前記最前構造物を支持する基礎が、直接基礎であり、
前記主構造物を支持する基礎が、杭基礎であり、
前記最前構造物が、前記直接基礎上に左右方向に沿って並列状態で構築されて上端に階段状の支持部を有する複数の支持壁と、当該複数の支持壁の支持部に亘って架設され、前記最前床部を構成するプレキャストコンクリート製の床板とを備えて構成されている点にある。 A first characteristic configuration of the present invention is a building provided with a floor on which spectator seats are provided on the upper surface and is inclined in a direction rising from the stadium side in front to the rear,
As the floor portion, a foremost floor portion located at the forefront portion and a main floor portion other than the foremost floor portion,
a foremost structure having the foremost floor is constructed separately from a main structure having the main floor;
a connecting portion connecting the foremost floor portion and the main floor portion;
The foundation supporting the frontmost structure is a spread foundation,
The foundation supporting the main structure is a pile foundation,
The forefront structure includes a plurality of support walls constructed in parallel along the left-right direction on the direct foundation and having stepped support portions at upper ends thereof, and a support portion extending over the support portions of the plurality of support walls. , and a precast concrete floor plate forming the foremost floor.

本構成によれば、前方の競技場側から後方に向けて上る方向に傾斜して観客席が上面に設けられた床部を備えた建築物が、互いに分離された最前構造物と主構造物とから構成されることになる。よって、最前構造物と主構造物との夫々の建設工事を工種を分けて並行して行うなどして、工期の短縮を図ることができる。
更に、低い側の最前床部を有する最前構造物が分離された主構造物は、従来のように低い側から高い側に亘る床部全体を設けた構造物と比較して、主床部の前方に向かう下り傾斜が地盤よりも充分に高い高さまでで終わるような整形なものとなる。よって、この主構造物の構造設計を簡素化することができる上に、それを構築するために必要な工期の短縮が可能となる。
従って、本発明により、前方の競技場側から後方に向けて上る方向に傾斜して観客席が上面に設けられた床部を備えた建築物において、構造設計の簡素化及び工期短縮を実現可能な技術を提供することができる。
更に、本構成によれば、主構造物から分離された最前構造物は、比較的低重量であることから、それを支持する基礎を比較的低コスト且つ短工期で構築可能な直接基礎とすることができる。
更に、本構成によれば、直接基礎上に並列状態で複数の支持壁を構築し、それら複数の支持壁の上端に形成された階段状の支持部に亘って、予め作成されたプレキャストコンクリート製の床板を架設させることができる。よって、当該床板を最前床部とする最前構造物を一層簡単且つ短工期で構築することができる。
また、このような最前構造物では、左右方向に延びる梁を省略することができる。よって、一層の低コスト化を図ることができる上に、内部空間を充分広くとって、当該内部空間の利用性を向上することができる。
更に、本構成によれば、主構造物は、比較的高重量であることから、それを支持する基礎を比較的高コスト且つ長工期で構築される杭基礎とすることができる。そして、主構造物の杭基礎の設置範囲を、従来のように床部全体を設けた一の構造物全体を杭基礎で支持する場合と比較して狭い範囲に制限して、杭基礎の設置工事による高コスト化及び長工期化を抑制することができる。 According to this configuration, the front structure and the main structure are separated from each other in the building provided with the floor section on which the spectator seats are provided on the upper surface and which is inclined in a direction rising backward from the stadium side in front. It will consist of Therefore, it is possible to shorten the construction period by dividing the construction work of the front structure and the main structure and performing them in parallel.
Furthermore, the main structure, in which the foremost structure having the foremost floor on the lower side is separated, has a lower main floor than the conventional structure in which the entire floor extending from the lower side to the higher side is provided. It should be shaped so that the downward slope towards the front ends at a height well above the ground. Therefore, the structural design of this main structure can be simplified, and the construction period required for constructing it can be shortened.
Therefore, according to the present invention, it is possible to simplify the structural design and shorten the construction period in a building with a floor that is inclined in a direction upward from the stadium side in front and has spectator seats on the upper surface. technology can be provided.
Furthermore, according to this configuration, since the forefront structure separated from the main structure is relatively light in weight, the foundation supporting it is a direct foundation that can be constructed at relatively low cost and in a short construction period. be able to.
Furthermore, according to this configuration, a plurality of supporting walls are constructed in parallel on the direct foundation, and the stepped support portions formed at the upper ends of the plurality of supporting walls are made of precast concrete made in advance. floorboards can be erected. Therefore, the forefront structure having the floor plate as the foremost floor can be constructed more easily and in a shorter construction period.
Moreover, in such a front structure, the beam extending in the left-right direction can be omitted. Therefore, further cost reduction can be achieved, and the internal space can be sufficiently widened to improve the usability of the internal space.
Furthermore, according to this configuration, since the main structure is relatively heavy, the foundation that supports it can be a pile foundation that can be constructed at a relatively high cost and in a long construction period. Then, the installation range of the pile foundation of the main structure is limited to a narrow range compared to the conventional case where the entire structure with the entire floor is supported by the pile foundation, and the pile foundation is installed. Higher construction costs and longer construction periods can be suppressed.

本発明の第２特徴構成は、前記最前構造物が、２階床高さ未満の構造物として構成されていると共に、
前記主構造物が、２階床高さ以上の構造物として構成されている点にある。 A second characteristic configuration of the present invention is that the frontmost structure is configured as a structure having a height of less than the second floor,
The main structure is constructed as a structure having a height of two floors or more.

本構成によれば、２階床高さ未満の最前構造物と２階床高さ以上の主構造物とを前後に配置して、当該最前構造物が有する最前床部と主構造物が有する主床部とを連設させることができる。このことで、主構造物は、１階床高さに満たない部分を有さない一層整形なものとなるので、この主構造物の構造設計を一層簡素化して工期短縮を図ることができる。
一方、最前構造物では、１階層分の内部空間を確保可能なものとなるので、当該空間を例えば倉庫等として有効利用することができる。また、最前構造物の最前床部と主構造物の主床部との連設部が２階床高さ部分となることから、当該２階床高さ部分に設けられた梁を用いて、主床部の前端部を支持することができる。 According to this configuration, a foremost structure having a height of less than two floors and a main structure having a height of two or more floors are arranged one behind the other, and the foremost floor portion of the foremost structure and the main structure have The main floor can be connected. As a result, the main structure has a more regular shape with no portion less than the height of the first floor, so that the structural design of the main structure can be further simplified and the construction period can be shortened.
On the other hand, since the frontmost structure can secure an internal space for one story, the space can be effectively used as a warehouse or the like. In addition, since the connecting part between the foremost floor part of the forefront structure and the main floor part of the main structure is the height of the second floor, using the beams provided at the height of the second floor, The front end of the main floor can be supported.

On the upper surface of the foremost structure 10, a stepped foremost floor portion 11 is provided, which is inclined in a direction upward from the vicinity of the stadium G as the floor portion toward the rear. On the other hand, the upper surface of the main structure 30 is provided with stepped main floors 31A and 31B that are inclined upward from the vicinity of the rear end of the foremost floor 11 toward the rear. The main floors 31A and 31B are composed of a front main floor 31A in the front half and a rear main floor 31B in the rear half. It is provided so as to incline in a direction upward from the upper position of the end portion toward the rear.
In the present embodiment, the floors 11, 31A, and 31B are configured as stepped floors, but the configuration can be appropriately changed, for example, by configuring the floors 11, 31A, and 31B in a flat plate shape with an inclined upper surface.

上記床部１１，３１Ａ，３１Ｂを構成する床板１２，３２は、プレキャストコンクリートで構成されており、例えば２段分の床板１２，３２を予めプレキャストコンクリートで構築し、その構築したプレキャストコンクリート製の床板１２，３２を複数並べて床部１１，３１Ａ，３１Ｂを構築することができる。 The floorboards 12 and 32 constituting the floor sections 11, 31A and 31B are made of precast concrete. A plurality of floors 11, 31A, 31B can be constructed by arranging a plurality of 12, 32.

主構造物３０において、床部３１Ａ，３１Ｂは、前方の競技場Ｇ側から後方に向けて上がる方向に延びる左右一対の傾斜大梁３３と、当該一対の傾斜大梁３３間に架設された前後一対の構造梁３４とによって支持されている。尚、本実施形態において、傾斜大梁３３の上面は後方に向けて上昇する階段状に形成されており、その上面に階段状の床部３１Ａ，３１Ｂ（床板３２）が設置されている。 In the main structure 30, the floors 31A and 31B are composed of a pair of left and right slanted girders 33 extending rearward from the stadium G side in an upward direction, and a pair of front and rear slanted girders 33 constructed between the pair of slanted girders 33. supported by structural beams 34; In this embodiment, the upper surface of the slanted girders 33 is formed in a stepped shape rising rearward, and stepped floors 31A and 31B (floor plates 32) are installed on the upper surface.

主構造物３０は、屋根構造物５０を支持する躯体として構成されている。即ち、主構造物３０には、床部３１Ｂから上方に突出する支柱部４０が設けられている。そして、屋根構造物５０は、前端部と後端部との間に位置する被支持部５１において主構造物３０の支柱部４０に支持され、後端部がバックステイ５５を介して主構造物３０の背面側に繋がれた片持ち式天秤トラス構造が採用されている。即ち、バックステイ５５は鋼管で構成されており、その上端部が上端接続部５６を介して屋根構造物５０の後端側に接続されており、その下端部が下端接続部５７を介して主構造物３０の背面側に接続されている。
以下、本実施形態の建築物１００が備える特徴構成について、説明を加える。 The main structure 30 is configured as a skeleton supporting the roof structure 50 . In other words, the main structure 30 is provided with a pillar portion 40 that protrudes upward from the floor portion 31B. The roof structure 50 is supported by the pillars 40 of the main structure 30 at the supported portion 51 located between the front end and the rear end, and the rear end is attached to the main structure via the back stay 55 . A cantilevered balance truss structure connected to the back side of 30 is adopted. That is, the backstay 55 is made of a steel pipe, and its upper end is connected to the rear end side of the roof structure 50 through an upper end connection portion 56, and its lower end is connected to the main body through a lower end connection portion 57. It is connected to the back side of the structure 30 .
The characteristic configuration of the building 100 of this embodiment will be described below.

本実施形態の建築物１００は、構造設計の簡素化及び工期短縮を実現可能とするための躯体分割構造を有する。
即ち、躯体分割構造は、図１及び図２に示すように、最前床部１１を有する最前構造物１０が、主床部３１Ａ，３１Ｂを有する主構造物３０から分離して構築され、最前床部１１と主床部３１Ａ，３１Ｂとを連設させる連設部２５を備えて構成されている。 The building 100 of the present embodiment has a split frame structure for realizing simplification of structural design and shortening of the construction period.
1 and 2, the front structure 10 having the front floor 11 is separated from the main structure 30 having the main floors 31A and 31B. It is configured with a connecting portion 25 connecting the portion 11 and the main floor portions 31A and 31B.

このような躯体分割構造を採用することにより、最前構造物１０と主構造物３０との夫々の建設工事を工種別に並行して行うことで、工期の短縮が図られている。更に、前方側に位置して低い最前床部１１を有する最前構造物１０が後方側に位置する主構造物３０に対して分離されることによって、当該主構造物３０の断面形状は、主床部３１Ａ，３１Ｂの前方に向かう下り傾斜が地盤よりも充分に高い高さまでで終わるような整形なものとなる。このことで、主構造物３０の構造設計が簡素化されると共に、その主構造物３０を構築するために必要な工期が短縮される。 By adopting such a divided frame structure, the construction work of the front structure 10 and the main structure 30 is performed in parallel according to the type of work, thereby shortening the construction period. Furthermore, by separating the foremost structure 10 located on the front side and having the lowest foremost floor 11 from the main structure 30 located on the rear side, the cross-sectional shape of the main structure 30 is the same as that of the main floor. The shape is such that the downward slope toward the front of the portions 31A and 31B ends up to a height sufficiently higher than the ground. This simplifies the structural design of the main structure 30 and shortens the construction period required to construct the main structure 30 .

最前構造物１０の高さについては適宜設定することができるが、本実施形態では、図１に示すように、最前構造物１０は、２階床高さ未満の構造物として構成されている。
一方、主構造物３０の高さについても適宜設定することができるが、本実施形態では、主構造物３０は、２階床高さ以上の構造物として構成されている。
即ち、２階床高さ未満の最前構造物１０と２階床高さ以上の主構造物３０とが前後に配置され、当該最前構造物１０が有する最前床部１１と主構造物３０が有する主床部３１Ａが、連設部２５において連設されている。 The height of the front structure 10 can be set as appropriate, but in this embodiment, as shown in FIG.
On the other hand, the height of the main structure 30 can also be set as appropriate, but in this embodiment, the main structure 30 is constructed as a structure with a height of two floors or more.
That is, a foremost structure 10 having a height of less than two floors and a main structure 30 having a height of two floors or more are arranged one behind the other, and the foremost floor 11 of the foremost structure 10 and the main structure 30 have The main floor portion 31A is connected at the connecting portion 25 .

この構成により、主構造物３０は、１階床高さに満たない部分を有さない一層整形なものとなる。そして、主構造物３０の構造設計が一層簡素化されて工期短縮が図られる。一方、最前構造物１０は、１階層分の内部空間１８を内部に確保可能なものとなる。そして、当該空間１８に面する後方側の壁面１６に適宜出入口１８ａを設けて、当該空間１８が倉庫等として有効利用されている。 This configuration makes the main structure 30 more regular with no portions less than one story high. Further, the structural design of the main structure 30 is further simplified, and the construction period is shortened. On the other hand, the forefront structure 10 can secure an internal space 18 for one story inside. A doorway 18a is appropriately provided on the wall surface 16 on the rear side facing the space 18, so that the space 18 is effectively used as a warehouse or the like.

最前床部１１と主床部３１Ａとを連設する連設部２５は、図２にも示すように、略２階床高さ部分において、最前構造物１０の最前床部１１の後端部の上面に対して主構造物３０の主床部３１Ａの前端部の下面を沿わせて載置されたものとして構成されている。この構成により、主床部３１Ａと最前床部１１とは、荷重の伝達については縁切りされた状態で前後方向に沿って相対移動可能に連設されることになる。
具体的には、主構造物３０の傾斜大梁３３は、前方の上記連設部２５に向けて片持ち状態で延出する片持ち梁部３３ａを有しており、その片持ち梁部３３ａの上面に設置された床部３１Ａの前端部が、最前構造物１０の最前床部１１の後端部の上面まで延出されている。そして、当該主床部３１Ａの前端部により、最前構造物１０と主構造物３０との間に形成された隙間の上方側の開口部が覆われている。 As shown in FIG. 2, the connecting portion 25 that connects the foremost floor portion 11 and the main floor portion 31A is the rear end portion of the foremost floor portion 11 of the foremost structure 10 at approximately the height of two floors. The lower surface of the front end portion of the main floor portion 31A of the main structure 30 is placed along the upper surface of the main structure 30. As shown in FIG. With this configuration, the main floor portion 31A and the foremost floor portion 11 are connected to each other so as to be relatively movable in the front-rear direction while the load transmission is cut off.
Specifically, the inclined girder 33 of the main structure 30 has a cantilevered beam portion 33a extending in a cantilevered state toward the connecting portion 25 in front, and the cantilevered beam portion 33a The front end portion of the floor portion 31A installed on the upper surface extends to the upper surface of the rear end portion of the foremost floor portion 11 of the foremost structure 10 . The front end of the main floor 31A covers the upper opening of the gap formed between the front structure 10 and the main structure 30 .

図２及び図３に示すように、主構造物３０から分離された最前構造物１０については、比較的低重量であることから、それを支持するための基礎は、地盤を改良してなる地盤改良層２２とその上に構築された布基礎２１とからなる直接基礎２０で構成されている。
一方、主構造物３０を支持する基礎については、比較的高重量であることから、それを支持するための基礎は、地盤に設けられた基礎杭４７とその基礎杭４７により支持されたフーチング４６とからなる杭基礎４５で構成されている。
このような基礎構造により、高コスト化及び長工期化の要因となる杭基礎４５の構築範囲が、建築物１００の構築範囲全体ではなく主構造物３０の構築範囲に制限されている。
尚、本実施形態では、最前構造物１０側を直接基礎２０とし、主構造物３０側を杭基礎４５としたが、例えば、最前構造物１０側及び主構造物３０側の双方を直接基礎とする、又は最前構造物１０側及び主構造物３０側の双方を杭基礎とするなどのように、最前構造物１０及び主構造物３０の基礎構造については適宜変更しても構わない。 As shown in FIGS. 2 and 3, the forefront structure 10 separated from the main structure 30 is relatively light in weight, so the foundation for supporting it is the ground made by improving the ground. It consists of a spread foundation 20 consisting of an improved layer 22 and a continuous foundation 21 built thereon.
On the other hand, since the foundation supporting the main structure 30 is relatively heavy, the foundation for supporting it consists of foundation piles 47 provided in the ground and footings 46 supported by the foundation piles 47. It is composed of a pile foundation 45 consisting of.
Due to such a foundation structure, the construction range of the pile foundation 45, which causes high cost and long construction period, is limited to the construction range of the main structure 30 rather than the entire construction range of the building 100.
In this embodiment, the front structure 10 side is the spread foundation 20, and the main structure 30 side is the pile foundation 45. For example, both the front structure 10 side and the main structure 30 side are spread foundations. Alternatively, the foundation structures of the front structure 10 and the main structure 30 may be changed as appropriate, such as using pile foundations on both the front structure 10 side and the main structure 30 side.

最前構造物１０では、図３に示すように、直接基礎２０上において前後に延びる複数の支持壁１５が左右方向に沿って並列状態で構築されている。そして、図２にも示すように、この複数の支持壁１５の上面が後方に向けて上昇する階段状の支持部１５ａとして形成されており、最前床部１１を構成するプレキャストコンクリート製の床板１２が、複数の支持壁１５の支持部１５ａに亘って架設される状態で設けられている。この構成により、床板１２を最前床部１１とする最前構造物１０が一層簡単且つ短工期で構築されることになる。
また、最前構造物１０では、左右方向に延びる梁が省略されている、このことで、一層の低コスト化が図られており、更には内部空間１８が充分広く確保されて当該内部空間１８の利用性が向上されている。
尚、この最前構造物１０の構成については、適宜変更することができる。 In the forefront structure 10, as shown in FIG. 3, a plurality of support walls 15 extending forward and backward on the direct foundation 20 are constructed in parallel along the left-right direction. As also shown in FIG. 2, the upper surfaces of the plurality of support walls 15 are formed as stepped support portions 15a rising rearward, and the floor plate 12 made of precast concrete that constitutes the foremost floor portion 11. is provided so as to extend over the support portions 15 a of the plurality of support walls 15 . With this configuration, the foremost structure 10 having the floorboard 12 as the foremost floor portion 11 can be constructed more easily and in a shorter construction period.
In addition, in the forefront structure 10, the beams extending in the left-right direction are omitted. Usability is improved.
Incidentally, the configuration of the forefront structure 10 can be changed as appropriate.
