Description

【0001】
【発明の属する技術分野】
この発明は、例えば、並列した複数のトンネル(中空部)を一体に形成してなる構造物などの、並列した状態の複数の中空部を有する中空構造物に関するものである。
【0002】
【従来の技術】
複数の中空部を有する中空構造物として、従来では、図2に示すように、各中空部20を構成している各上壁部材21と各底壁部材22とが同一レベルに位置しており、同一規模の空間で構成した各中空部20を同一面上に複数並列するような形態のものが一般に知られている。
【0003】
【発明が解決しようとする課題】
前述した従来の中空構造物は、上面が傾斜している盛土部分に設置するのには不向きなものであった。
【0004】
詳述すると、例えば、図2に示すように、河川に橋23を架ける場合その橋23の桁高Lを一定以上確保するためには、橋23に向かって上面が傾斜した盛土部分24を形成して、橋23への導入路25を作る必要がある。
【0005】
そして、この盛土部分はその周辺地域を分断してしまうこととなるので、従来から、盛土部分にトンネル(中空部)を形成して、盛土部分の中を通行できるようにすることが行われている。
【0006】
このトンネル(中空部)の形成は、盛土後に掘削するよりも、中空構造物の設置後その上に盛土した方が、簡単に短時間で行える。
【0007】
ところが、前述した従来の中空構造物を設置した後に盛土しようとすると、図に示すように、従来の中空構造物26の各上壁部材21は同一レベルに位置しているので、上壁部材21と盛土部分24の傾斜した上面24aとが干渉してしまい、傾斜した上面24aを形成することができなくなってしまう。
【0008】
なお、中空部が一つの中空構造物を盛土の最も高い部分一か所のみに設置すれば、傾斜した上面に関係なく、トンネル(中空部)を形成することはできる。しかし、例えば、二車線にすることや、車と人とを別けて通行させることができない等、盛土部分の有効利用ができなくなる。
【0009】
このように、前述した従来の中空構造物では、トンネル(中空部)の形成は簡単に短時間で行えるものの、その複数の中空部を有効に利用することが、即ち、盛土部分を有効利用できるようにすることができなかった。
【0010】
この発明は前述した事情に鑑みて創案されたもので、その目的は上面が傾斜している盛土部分に容易に対応することができて、その盛土部分を有効利用できるようにする複数の中空部を有する中空構造物を提供することにある。
【0011】
【課題を解決するための手段】
この発明での中空構造物は、幅方向に対向立設している両側壁部材と、この両側壁部材に幅方向に跨がるように接合している上壁部材と、両側壁部材の下端部間に設けている底壁部材とを長手方向に連結して、内部に長手方向へ指向する複数の中空部を形成していると共に、この中空部を並列した状態で複数形成してなるものとする。
【0012】
そして、この発明の中空構造物の各中空部を形成している各底壁部材は、同一面上の位置に設置している。また、中空構造物の各中空部を形成している各上壁部材は、各中空部毎にその並列方向へ徐々に底壁部材の方向へ移動する位置に設置されており、各中空部の仕切り壁となっている側壁部材は、その先端部分が断面略Y字状に枝分かれしており、一方が高い位置に延びていると共に、他方が低い位置に延びている
【0013】
このようなこの発明の複数の中空部を有する中空構造物によれば、設置位置が、各中空部毎にその並列方向へ徐々に、底壁部材の方向へ移動している各上壁部材に沿って、盛土部分の傾斜した上面を形成できるようにしている。
【0014】
このことから、この発明の中空構造物を用いれば、盛土部分の傾斜した上面に対応して中空部を複数形成できるようになり、盛土部分を有効利用することができるようになる。
【0015】
【発明の実施の形態】
以下、この発明の複数の中空部を有する中空構造物を、図示する一実施形態によって説明する。
【0016】
中空構造物1(図1参照)は、幅方向に対向立設している両側壁部材2と、この両側壁部材2に幅方向に跨がるように接合している上壁部材3と、両側壁部材2の下端部間に設けている底壁部材4とを長手方向に連結して、内部に長手方向へ指向する複数の中空部5を形成していると共に、この中空部5を並列した状態で複数形成してなっている。
【0017】
そして、この中空構造物1の各中空部5を形成している各底壁部材4は、同一面上の位置に設置している。また、中空構造物1の各中空部5を形成している各上壁部材3は、各中空部5毎にその並列方向へ徐々に底壁部材4の方向へ移動する位置に設置している。
【0018】
なお、この実施形態での中空構造物1は、図1に示すように、河川6に橋7を架ける場合で、その橋7に向かって上面8aが傾斜するように形成した盛土部分8に設けている。
【0019】
また、この実施形態での中空構造物1は、その中空部5を四個形成しており、河川6側の中空部5が最も大きな規模になると共に、河川6から離れるにつれて小さな規模となるように構成している。
【0020】
即ち、中空構造物1は、その各中空部5を構成している各上壁部材3の設置位置が、各中空部5毎にその並列方向へ徐々に底壁部材4の方向へ移動して、各上壁部材3が、河川6から離れる方向へ下がる傾斜である盛土部分8の上面8aに沿って設置される状態となっている。
【0021】
さらに、この実施形態での中空構造物1は、両側壁部材2と上壁部材3とを別部材にして予め製作しておき、その各部材を施工現場にて組立てることで構成している。また、底壁部材4は、施工現場にてコンクリートを打設することで形成している。
【0022】
この中空構造物1は、その両側壁部材2と上壁部材3と底壁部材4とを一体に成形したものでもよい。
【0023】
この実施形態での各中空部5の仕切り壁となっている側壁部材2は、その先端部分が断面略Y字状に枝分かれしており、各中空部5毎にその並列方向へ徐々に底壁部材4の方向へ移動している各上壁部材3に対応して、一方が高い位置に延びていると共に、他方が低い位置に延びている。
【0024】
このような構成からなる複数の中空部5を有する中空構造物1を用いれば、その各上壁部材3の設置位置が、各中空部5毎にその並列方向へ徐々に、底壁部材4の方向へ移動していることにより、中空構造物1の上に盛土した場合、各上壁部材3に沿って、盛土部分8の傾斜した上面8aを形成することがてきる。
【0025】
このことから、この発明の中空構造物1を用いれば、盛土部分8上面8aの傾斜に対応して中空部5を複数形成できるようになって、盛土部分8を有効利用することができるようになる。
【0026】
【発明の効果】
この発明の複数の中空部を有する中空構造物では、中空構造物構成用である各上壁部材の設置位置が、各中空部毎にその並列方向へ徐々に、中空構造物構成用である底壁部材の方向へ移動している。
【0027】
そのため、この中空構造物の上に盛土した場合に、各上壁部材に沿って、盛土部分の傾斜した上面を形成することができる。
【0028】
このことから、この発明の中空構造物を用いれば、盛土部分上面の傾斜に対応して中空部を複数形成できるようになって、盛土部分を有効利用することができるようになる。

However, when embankment is attempted after the above-described conventional hollow structure is installed, the upper wall members 21 of the conventional hollow structure 26 are positioned at the same level as shown in the figure. And the inclined upper surface 24a of the embankment portion 24 interfere with each other, and the inclined upper surface 24a cannot be formed.
[0008]
In addition, if a hollow structure with one hollow part is installed only at the highest part of the embankment, a tunnel (hollow part) can be formed regardless of the inclined upper surface. However, effective use of the embankment part becomes impossible, for example, it is not possible to use two lanes or to separate cars and people.

The bottom wall member provided between the parts is connected in the longitudinal direction to form a plurality of hollow parts oriented in the longitudinal direction inside, and a plurality of these hollow parts are formed in parallel. And
[0012]
And each bottom wall member which forms each hollow part of the hollow structure of this invention is installed in the position on the same surface. Further, each upper wall member forming each hollow part of the hollow structure is installed at a position where each hollow part gradually moves in the direction of the bottom wall member in the parallel direction. As for the side wall member which is a partition wall, the front-end | tip part has branched in cross-sectional substantially Y shape, and while the other is extended to the high position, the other is extended to the low position .
[0013]
According to such a hollow structure having a plurality of hollow portions of the present invention, the installation position of each upper wall member that is gradually moving in the parallel direction for each hollow portion in the direction of the bottom wall member. Along the slope, an inclined upper surface of the embankment portion can be formed.
[0014]
From this, if the hollow structure of this invention is used, a plurality of hollow parts can be formed corresponding to the inclined upper surface of the embankment part, and the embankment part can be used effectively.
