Description
【発明の詳細な説明】 本発明は、複合コンクリート製品に関する。[Detailed description of the invention] The present invention relates to composite concrete products.
従来、強化プラスチック環体（以下Ｆ’Ｂ、Ｐ環体とい
う）をコンクリート管又はパイル（以下コンクリート管
という）の外層および／″または内層に配設したものは
、複合コンクリート管として提案されている。本発明は
、上記複合コンクリート管の強度特性を一層向上させよ
うとするもので、その要旨は、軸方向または周方向に補
強リブを設けてなる強化プラスチック環体を外層の一部
又は全部に構成した複合コンクリート製品にある。Conventionally, a reinforced plastic ring (hereinafter referred to as F'B, P ring) arranged on the outer layer and/or inner layer of a concrete pipe or pile (hereinafter referred to as concrete pipe) has been proposed as a composite concrete pipe. The present invention aims to further improve the strength characteristics of the above-mentioned composite concrete pipe, and its gist is that a reinforced plastic ring body provided with reinforcing ribs in the axial or circumferential direction is provided in part or all of the outer layer. It consists of composite concrete products.
図面に示すものは実施例であって、これは、局長に対し

クリート管であり、図において、３はコンクリート層で
ある。What is shown in the drawing is an example, in which the entire outer layer is constructed with an FRPJJ body 2, which is provided with reinforcing ribs 1 in the axial direction and arranged equally at 25% intervals. It is a concrete pipe, and in the figure, 3 is a concrete layer.
上記補強リプ１は、局長に対して、５％間隔で、等分に
配列して設けてもよく、Ｆ几Ｐ環体２の厚さは管径に応
じて適宜選ぶが、例えば１〜１０ｍであシ、補強リプ１
の厚さは例えば３〜２０絽、その巾は５〜３０ｉｏａで
おる。The reinforcing ribs 1 may be equally arranged at 5% intervals with respect to the length of the pipe, and the thickness of the F ring P ring body 2 may be appropriately selected depending on the pipe diameter, but for example, 1 to 10 m. Ashi, reinforcement reply 1
The thickness is, for example, 3 to 20 ka, and the width is 5 to 30 ioa.
また、補強リプ１はＦＢ、Ｐ＠体２０周方向に設けるこ
ともでき、この場合、管長に対して１０〜３０％の間隔
を保つ。Further, the reinforcing lip 1 can also be provided in the circumferential direction of the FB, P body 20, and in this case, a spacing of 10 to 30% with respect to the pipe length is maintained.
上記ＦＲＰ壌体２は、コンク、リート管の一部、例えば
、両端部のみ、または全長にわたって設けることができ
る。The above-mentioned FRP platform 2 can be provided in a part of the conch or riet pipe, for example, only at both ends, or over the entire length.
上記コンクリート管を成形するには、予め工場において
、ＦＲＰ３１１体を成形しておき、これを遠心力成形用
型枠内の所定位置に配置したのち、通常の方法で、所定

Ｊ体を形成し、硬化又はある程度硬化したのち、常法に
よってコンクリートを供給して、管体を成形する。In order to form the above-mentioned concrete pipe, a 311-piece FRP body is formed in advance at a factory, placed in a predetermined position within a formwork for centrifugal force forming, and then concrete is poured to a predetermined pipe thickness using the usual method. FRPE is supplied and centrifugally formed, or FRPE is formed in a centrifugally formed form using a waste mold.
After the J-body is formed and hardened or hardened to some extent, concrete is supplied using a conventional method to form a pipe.
さらにまた、ＦＲＰＪＪ１体２は、これをコンクリート
管の外層のみでなく、内層に形成することもできる。内
層に形成する場合、補強リプ１は、Ｆ’Ｂ、Ｐ環体の外
面に設けられる。Furthermore, the FRPJJ body 2 can be formed not only in the outer layer of the concrete pipe but also in the inner layer. When formed on the inner layer, the reinforcing lip 1 is provided on the outer surface of the F'B, P ring body.
図示のものは、コンクリート管に関する具体例であるが
、同様の構造によってコンクリートパイル、コンクリー
トウェル等を形成するととができる。Although the illustrated example relates to a concrete pipe, concrete piles, concrete wells, etc. can be formed using a similar structure.
本発明によれば、ＦＲＰ複合管の構造強度を高めること
ができる。According to the present invention, the structural strength of the FRP composite pipe can be increased.
