【発明の属する技術分野】
本発明は、埋設配管を支持する枕台の配置間隔を調節するため、枕台と枕台の間に設置されて適宜な間隔に枕台を支持する保持具に関する。
【０００２】
【従来の技術及び発明が解決しようとする課題】
ケーブル保護管を地中に埋設する際、地中で管体を支持する枕台が使用されている。
この枕台５は、図５に示されるように、管体の周面が接合する半円弧状の管受部５１を上面に有するとともに管受部５１の両側の相対する位置に互いに嵌合し得る窪み５２ａと突起５２ｂを設けてブロック状に形成されており、枕台同士を互いに向きを反転させて上下に向かい合わせ、且つ窪み５２ａと突起５２ｂを嵌合させて一体化することにより上下枕台間に形成される円形開口部内に管体を挿通して支持し、埋設位置に固定するように構成されている。
また、枕台５の左右側面には、相互に嵌合する連結部としての凹部５３ａと凸部５３ｂがそれぞれ設けられ、隣接配置される枕台同士を連結できるようになっているとともに、枕台５の下面両側の相対する位置にも相互に嵌合する連結部としての窪み５４ａと突起５４ｂ、又は凹部５５ａと凸部５５ｂがそれぞれ設けられ、上下に配置される枕台同士も連結できるようになっている。
【０００３】
このような枕台５を使用した従来の配管支持構造において、縦横複数列に支持された管体の配置間隔を広げる場合は、例えば特許第２７１０２２４号公報に記載されたような適宜な幅のスペーサを枕台間に介装させ、枕台の配置間隔を広げるようにしていた。
この場合、一般に枕台５は、配管の作業性と安定性を考慮し、その左右側面と下面の連結部の構造を異ならせて形成されることが多く、そのため、枕台５の左右側面に連結する接続構造を備えたスペーサと、枕台５の下面に連結する接続構造を備えたスペーサの二種類を準備し、左右に並んだ枕台間を広げるときは前者を用い、上下に重ねた枕台間を広げるときは後者を用いるようにしていた。
【０００４】
本発明は従来技術の有するこのような問題点に鑑み、一つの保持具のみで、枕台の左右側面と下面とに接合して上下左右両方向に枕台の配置間隔を広げることができるようにすることを課題とする。
【０００５】
【課題を解決するための手段】
前記課題を解決するため本発明の配管枕台用保持具は、上面に管受部が設けられているとともに左右側面及び下面にそれぞれ連結部が設けられてなる配管枕台同士を支持する保持具であって、適宜な高さのリブを介して連結された上下両面が前記配管枕台の左右側面と下面とに接合可能に形成され、且つその面内に前記配管枕台左右側面の連結部に連結する連結凹部と、下面の連結部に連結する連結凹部とが設けられてなることを特徴とする。
前記構成の保持具において、前後縁部に配管枕台の前後縁部に係合する突片が設けられていることが好ましい。
【０００６】
これによれば、枕台の側面と下面に接合する面内に両面の連結部に連結する連結凹部を設けて保持具を構成してあるので、上下枕台間に保持具を配置して枕台の上下方向の配置間隔を広げ、また、左右枕台間に保持具を配置して枕台の左右方向の配置間隔を広げて連結した枕台を支持することができる。
また、保持具の前後縁部に突片が設けてあれば、枕台の縁部に突片を係合させて保持具両側の枕台の位置を規制でき、枕台を適正な連結位置で支持することができる。
なお、保持具に設ける連結凹部は、枕台に設けられた連結部が突起の場合は窪み、凸部の場合は凹部というように、枕台に設けられた連結部の形状に対応した形状に設けることができる。
【０００７】

【００１２】
このように形成された本形態の保持具２によれば、上下に重なる一体化した枕台３、３と一体化した枕台３、３との間に二つの保持具２、２を互いに向きを反転させて並べ、それぞれ枕台３、３の突起３４ｂ、３４ｂを窪み２２ａ、２２ａに嵌合させて、それぞれ上面２２及び下面２３を上下の枕台３、３に接合させることにより、枕台３の上下方向の配置間隔を広げることができる。また、左右に隣接する一体化した枕台３、３と一体化した枕台３、３との間に二つの保持具２、２を互いに向きを反転させて並べ、それぞれ両側の枕台３、３の凸部３３ｂ、３３ｂを凹部２２ｂ、２２ｂに嵌合させて、それぞれ上面２２及び下面２３を左右の枕台３、３に接合させることにより、枕台３の左右方向の配置間隔を広げることができる。これらの場合に、保持具２の上面２２側が一側の枕台３に嵌合し、他側の枕台３には連結されないが、下面２３の前後縁部に設けられた突片２４、２４が他側の枕台３の前後縁部にそれぞれ係合するので、保持具両側の枕台３、３の位置が規制され、位置をずらすことなく、枕台３、３を適正な連結位置に支持することができる。

The recesses 52a and the protrusions 52b are provided to form a block, and the pillows are turned upside down so that they face each other up and down, and the recesses 52a and the protrusions 52b are fitted and integrated to form a pillow. The pipe is inserted and supported in a circular opening formed between the tables, and is fixed at the buried position.
In addition, a concave portion 53a and a convex portion 53b are provided on the left and right side surfaces of the pillow base 5 as connecting portions to be fitted to each other, so that the pillow bases arranged adjacent to each other can be connected. A recess 54a and a projection 54b, or a concave portion 55a and a convex portion 55b, are provided at opposite positions on both sides of the lower surface of the lower surface 5 so as to be connected to each other. Has become.
[0003]
In the conventional piping support structure using such a pillow bed 5, when the arrangement interval of the pipes supported in a plurality of rows and columns is increased, for example, a spacer having an appropriate width as described in Japanese Patent No. 27210224 is used. Was interposed between the pillow beds to increase the spacing between the pillow beds.
In this case, in general, the pillow bed 5 is often formed with different structures of the connecting portion between the left and right side surfaces and the lower surface in consideration of workability and stability of the piping. Two types of spacers, a spacer having a connection structure to be connected and a spacer having a connection structure to be connected to the lower surface of the pillow table 5, were prepared. The latter was used when extending the space between pillow beds.
