本発明は、高層建築物の排水管システム等に用いられる
排水用継手管に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a drainage joint pipe used in a drainage pipe system of a high-rise building, etc.
（従来の技術）
排水が排水管を流下する際、管断面全域に亘って流下す
ると、流下に伴ない下流側の管内圧が上昇し、排水管に
接続されるトイレ等排水器具の封水トラップが破られる
ことになる。そのため、排水管内周面に旋回付与羽根を
設け、排水を旋回流とすることで管内周に沿って流下さ
せ、管軸に沿って上下貫通状の空気コアを形成すること
で管内圧の上昇防止を図ったものが従来よりある。(Prior art) When wastewater flows down a drain pipe, if it flows down over the entire cross section of the pipe, the pressure inside the pipe on the downstream side increases as it flows down, causing a water sealing trap for drainage equipment such as toilets connected to the drain pipe. will be broken. Therefore, swirling blades are installed on the inner circumferential surface of the drain pipe to create a swirling flow in the waste water, causing it to flow down the inner circumference of the pipe, and by forming an air core that penetrates vertically along the pipe axis, the pressure inside the pipe is prevented from increasing. There are conventional methods that aim to achieve this.
しかし、旋回付与羽根は流路を狭くするため、未だ旋回
流となっていないために管断面積全域に亘って流下する
排水が、旋回付与羽根の部分で詰まってしまって管を閉
塞し、上下貫通状の空気コアの形成を阻害する虞れがあ
る。However, since the swirling blades narrow the flow path, the drainage water flowing down over the entire cross-sectional area of the pipe, which has not yet formed a swirling flow, becomes clogged at the swirling blades and blocks the pipe, causing the flow to flow upward and downward. There is a possibility that formation of a penetrating air core may be inhibited.
そこで、特願昭５８−１２００１８号に示すように、立
排水管よりも径大の膨大部を有する排水用継手管におい
て、その膨大部に旋回付与羽根を設け、排水管の詰まり
を防止したものがある。Therefore, as shown in Japanese Patent Application No. 58-120018, a joint pipe for drainage having an enlarged part with a diameter larger than that of a vertical drainage pipe is provided with swirling blades in the enlarged part to prevent clogging of the drain pipe. There is.
（発明が解決しようとする問題点）
膨大部に旋回付与羽根を設けた継手管では、排水の詰ま
りは防止できるが、膨大部では排水が径方向に分散され

なくなる。そこで、偏流ガイドを設けて排水を一側方に
偏流させて羽根に案内することがなされているが、排水
量や流下速度の如何によっては羽根位置に正確に案内で
きず、旋回の付与ができないという問題がある。(Problem to be Solved by the Invention) A joint pipe in which turning blades are provided in the ampullae can prevent drainage clogging, but since the drainage is dispersed in the radial direction in the ampulla, It will not be possible to provide sufficient amounts. Therefore, a drifting guide is installed to divert the wastewater to one side and guide it to the blades, but depending on the amount of drainage and the flow rate, it may not be possible to guide the wastewater accurately to the blade position, and it may not be possible to create a swirl. There's a problem.
