COLLECTIVE JOINT SYSTEM
To provide a collective joint system with improved drainage performance and sound insulation.SOLUTION: A collective joint system includes a collective joint 11 and a vertical pipe. The collective joint is equipped with a joint body 16 arranged so that an axis line O follows the vertical direction, and a swivel vane 34 provided on the inner circumference of the joint body. Where a line including a connection portion 32b between the swing vane and the joint body in a transverse view orthogonal to the axis line of the swing vane, extending downwardly toward a first side X1 in the circumferential direction and an end 34c opposite to the connection portion of the swivel vane is set as a reference line L2, area ratio of a region R6, which is an internal space of the joint body and is opposite to the tip of the swirl vane on the first side with respect to the reference line, relative to the internal space of the joint body is 30% or more when viewed downward in a cross-sectional view, regardless of the axial position of the cross-section, and area ratio of the swivel vane in the internal space of the vertical tube to the area of the internal space of the vertical tube is 5% or more and 30% or less in plane view.SELECTED DRAWING: Figure 4
【課題】排水性能及び遮音性を高めた集合継手システムを提供する。【解決手段】集合継手システムは、集合継手１１と、縦管と、を備え、集合継手は、軸線Ｏが上下方向に沿うように配置される継手本体１６と、継手本体の内周面に設けられた旋回羽根３４と、を備え、旋回羽根は、下方に向かうに従い周方向の第１側Ｘ１に向けて延び、旋回羽根の軸線に直交する横断面視における、旋回羽根と継手本体との接続部分３２ｂと、旋回羽根における接続部分とは反対側の端３４ｃと、を含む線を基準線Ｌ２としたときに、横断面視で下方に見たときに、継手本体の内部空間の面積に対する、継手本体の内部空間であって、基準線よりも旋回羽根の第１側の先端とは反対側の領域Ｒ６の面積の比率が、横断面の軸線方向の位置によらず３０％以上であり、平面視において、縦管の内部空間の面積に対する、縦管の内部空間内の旋回羽根の面積の比率が、５％以上３０％以下である。【選択図】図４
