DOWN-PIPE JOINT
To provide a down-pipe joint which has high versatility and can reduce production costs.SOLUTION: A drainage pipe cover 60 includes: a large-diameter cylindrical part 65 to which a lower side of a down pipe is internally fitted; and an upper end part 77 having an outer peripheral face part 76 which is connected to a lower end part of the large-diameter cylindrical part 65 and whose diameter becomes larger as it goes downward. The outer peripheral face part 76 includes: a cover part 75 having a conical outer peripheral face part 78; a small-diameter cylindrical part 70 extending downward from the lower end part via a connection annular part 80 whose diameter becomes smaller as it goes downward, and arranged on a radially inner side of the cover part 75; and an annular rib 85 including a part located above a joint part 86 of the lower end part and the upper end part 77, arranged in the same axial position, and projecting to the radially inner side from an inner peripheral face. A cylindrical member is formed which has more than one engaging parts on an inner peripheral side of the lower end part, projecting to the radially inner side and composed of at least a part of the rib 85, by cutting a proper place of the drainage pipe cover 60 in the radial direction.SELECTED DRAWING: Figure 6
【課題】汎用性が高くて、製造コストを低減できる竪樋用継手を提供すること。【解決手段】排水管カバー６０が、竪樋の下側が内嵌される大径円筒部６５、大径円筒部６５の下側端部に繋がると共に下側に行くにしたがって大径になる外周面部７６を有する上側端部７７を含み、外周面部７６が、円錐外周面部７８を有するカバー部７５、上記下側端部から下側に行くにしたがって小径になる連結環状部８０を介して下側に延在し、カバー部７５よりも径方向内側に配置される小径円筒部７０、及び上記下側端部と上側端部７７の接続箇所８６よりも上側に位置する部分を含んで軸方向の同じ箇所に設けられると共に、内周面から径方向の内側に突出する環状のリブ８５を備える。排水管カバー６０の適切な箇所を径方向に切断することで、径方向内側に突出すると共にリブ８５の少なくとも一部で構成される１以上の係止部を下側端部の内周側に有する筒状部材を形成する。【選択図】図６
