PIPING JOINT
To provide a piping joint which is easy in installation work.SOLUTION: A piping joint 1 comprises: a cylindrical joint main body 10; a flange part 14 arranged at an external peripheral face of the joint main body 10, and having a flange-part side insertion hole 14a into which a screw fixed to a construction face is inserted; and a packing 50 for sealing a clearance between the flange part 14 and the construction face, having a center hole 50a into which the joint main body 10 is inserted, and also having a seal member-side insertion hole 50c into which the screw is inserted. A whirl-stop protrusion 15a is formed at an external peripheral face of the joint main body 10, and a whirl-stop recess 50b is formed at a peripheral edge of the center hole 50a of the packing 50. In a state that the whirl-stop protrusion 15a of the joint main body 10 and the whirl-stop recess 50b of the packing 50 are engaged with each other in a peripheral direction, the relative movement of the joint main body 10 and the packing 50 is prohibited.SELECTED DRAWING: Figure 2
【課題】 設置作業が容易な配管用継手を提供すること。【解決手段】 配管用継手１は、円筒状の継手本体１０と、継手本体１０の外周面に設けられ、施工面に対して固定するためのビスが挿通されるフランジ部側挿通孔１４ａを有するフランジ部１４と、フランジ部１４と施工面との間をシールするものであって、継手本体１０が挿通された中心孔５０ａを有するとともにビスが挿通されるシール部材側挿通孔５０ｃを有するパッキン５０とを備えている。継手本体１０の外周面には回り止め凸部１５ａが、パッキン５０の中心孔５０ａの周縁には回り止め凹部５０ｂがそれぞれ設けられている。継手本体１０の回り止め凸部１５ａとパッキン５０の回り止め凹部５０ｂとが周方向に係合した状態では、継手本体１０とパッキン５０との相対回動が阻止される。【選択図】 図２
