Description

【考案の詳細な説明】 本考案は排水管として使用される卵形管の接続部に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting part of an oval tube used as a drain pipe.

従来、卵形管を接続して使用する場合、巾及び厚さが各
部分で均一な環状バッキングを用いて、管受口内に管挿
口を挿着することがある。Conventionally, when oval tubes are connected and used, an annular backing having a uniform width and thickness at each portion is used to insert a tube socket into a tube socket.

しかし、卵形管は長軸をたてて小湾曲部側を下にして土
中に埋設されるため、配管路上の上圧及び輪圧は地盤不
等沈下時に接続部の底部の小湾曲部に集中し、接続部の
底部の小湾曲部を破損したり、接続部から水洩れが発光
したりしやすい。However, since egg-shaped pipes are buried in the soil with their long axes erected and the small curved part side down, the upper pressure and ring pressure on the pipeline will be reduced at the small curved part at the bottom of the connection when the ground settles unevenly. Water leaks from the connection and tends to damage the small curved part at the bottom of the connection, or cause water to leak from the connection.

本考案は叙上の如き従来の欠点を解消することを目的と
してなされたもので゛あって、その要旨は、管受口内に
環状バッキングを介して管挿口が挿入接続された卵形管

ングが装着されてなる卵形管の接続部に存する。The present invention was developed with the aim of solving the above-mentioned conventional drawbacks, and its gist is that of an oval tube in which a tube inlet is inserted and connected to the tube socket through an annular backing. At the connection part, an annular backing is installed in the gap between the tube socket and the tube inlet, and the backing is wide on the small curved side of the oval tube and narrow on the large curved side. Exists.

以下、本考案を図面の実施例により説明する。Hereinafter, the present invention will be explained with reference to embodiments of the drawings.

図は第１図のＩＩ −ＩＩ線に沿う断面図である。Fig. 1 is a partially cutaway front view showing an embodiment of the present invention;
The figure is a sectional view taken along line II-II in FIG. 1.

１は第１の卵形管であり、一端に管受口１１が設けられ

１４の方を上にして載置されている。Reference numeral 1 designates a first oval tube, which has a tube socket 11 at one end, a groove 12 along the circumferential direction on the inner peripheral surface of the tube socket 11, and a small curved tube with its long axis erected. It is placed with the portion 13 facing down and the large curved portion 14 facing up.

広巾部２１と相対抗する部分が狭巾部２２とされ、広巾
部２１から狭巾部２２まで連続的に巾が変えられている
ものである。2 is an annular backing, one of which is a wide part 21;
A portion opposing the wide width portion 21 is a narrow width portion 22, and the width is continuously changed from the wide width portion 21 to the narrow width portion 22.

第１の卵形管１の凹溝１２に、環状バッキング２が広巾
部２１を小湾曲部１３の方へ向け、狭巾部２２を大湾曲
部１２の方へ向けて装着されている。An annular backing 2 is attached to the groove 12 of the first oval tube 1 with the wide part 21 facing the small curved part 13 and the narrow part 22 facing the large curved part 12.

３は第２の卵形管であり、一端が管挿口３１とされてい
る。3 is a second oval tube, one end of which is a tube insertion port 31.

第１の卵形管１の管受口１１内に、第２の卵形管３の管
挿口３１が小湾曲３２の方を下に、大湾曲部３３の方を

される。The tube insertion port 31 of the second oval tube 3 is inserted into the tube socket 11 of the first oval tube 1 with the small curve 32 facing downward and the large curve 33 facing upward, The gap between the tube socket 11 and the tube insertion port 31 is wide on the side of the small curve of the oval tube and narrow on the side of the large curve. A connection of an oval tube fitted with an annular backing 2 is formed.

叙上の如く、本考案卵形管の接続部は、管受口と管挿口

とがない。As mentioned above, in the connecting part of the oval tube of the present invention, an annular backing is installed in the gap between the tube socket and the tube insertion port, and the backing is wide on the small curve side of the oval tube and narrow on the large curve side. Therefore, when it is buried underground and used, the wide part of the annular packing absorbs the load applied to the small curved part at the bottom of the oval tube due to the eccentric load caused by the ground subsidence of the tonosho and ring pressure. However, it does not damage the small curved part at the bottom of the connection part or cause water leakage from the connection part.
