【産業上の利用分野】
本発明は鞘管の接続構造に関する。
【０００２】
【従来の技術】

【０００３】
この鞘管ヘッダー式配管システムでは、鞘管同士を接続するとき、相接続される鞘管の相突き合わされる端部のそれぞれを筒状カップリングの内径部に差し込み、上記カップリングの一端回りの両側面に２個の半円リング状のクランプ部材を当てがってそれら２個のクランプ部材をねじ止めにて締結するとともに、上記カップリングの他端回りにも同様に２個のクランプ部材をねじ止めして締結することとしている。
【０００４】
【発明が解決しようとする課題】
然しながら、従来技術には、下記(a) 〜(c) の問題点がある。
(a) カップリングの内径部に鞘管同士を差し込んで相突き合わすものであるから、鞘管同士の接続部端面間の間隙が内管の通管領域に対して段差をもって臨むものとなる。このため、内管の通管時に、内管の先端部が上記段差に突っ掛かり、通管作業性を損なう。
【０００５】
(b) カップリングの両側から２つの鞘管のそれぞれを差し込んで相突き合わすに際し、接続品質を維持するためには、両鞘管の端部をカップリングの中央に位置させる必要があるが、その位置決めに困難がある。
【０００６】
(c) カップリングの両端のそれぞれにおいて、２個の半円リング状クランプ部材をねじ止めするものであるから、ねじ止め箇所が多い上に広い作業スペースが必要であり、接続作業にも困難がある。
【０００７】

The clamp 31 is fastened around the connecting portions of the sheath tubes 11, 11 to be connected in phase, where the connecting core 13 is inserted. At this time, the clamp 31 has a receiving tool 32 and a fixing saddle 33. The receiving member 32 is formed of resin or metal, and is fixed to a building structural material such as a floor member 35 by a set screw 34 so as to receive a lower half portion of the sheath tube 11 around the connection portion. The fixing saddle 33 is formed of resin or metal, is attached to the upper half of the sheath tube 11 around the connection portion, and is set with a set screw so that the sheath tube 11 is held between the sheath tube 11 and the receiving member 32. By 36, it is fixed to a building structural material such as a floor material 35.
[ 0036 ]
Therefore, according to the third embodiment, the clamp 31 is composed of the receiving member 32 and the fixing saddle 33, and the receiving member 32 and the fixing saddle 33 are respectively fixed to the building structural material. The connection portion of the sheath tube 11 can be easily fixed to the floor material 35 at the same time as fastening.
[ 0037 ]
As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration of the present invention is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention. Included in the present invention. For example, when inserting the connection core into the inner diameter portion of the sheath tube to be connected in phase, a seal member such as an O-ring is interposed between the inner diameter portion of the sheath tube and the outer peripheral portion of the connection core, and the inside and outside of the sheath tube connection portion are inserted. May be used for water sealing.
