している。(Prior Art) For example, as a pipe joint for a drain pipe, the one shown in FIG. 5 is known. This pipe joint 10 is made of an elastic material such as rubber, has a bellows part 11 formed in the middle part, and has flat outer peripheral surfaces at both ends 10a and 10b. And during construction,
The tips of the two tubes 12 and 13 are connected to both ends 10a and 1
0b, and tighten the tightening band 1 around the circumference.

た。(Problems to be Solved by the Invention) Although the conventional pipe joint 10 described above has the advantage that the bellows portion 11 absorbs displacement caused by earthquake motion or dimensional errors during construction,
Since the outer circumferential surfaces of both ends 10a and 10b into which 3 is inserted are flat circumferential surfaces, there is a limit to the tightening force by the tightening band 14.
There was a problem that the liquid tightness between a, 10b and the pipes 12, 13 was insufficient, and there was a risk of water leakage.
この考案は上記のような従来の問題点を解決
し、漏水を確実に抑えることができる管継手を提
供することを目的とする。 The purpose of this invention is to solve the above-mentioned conventional problems and provide a pipe joint that can reliably suppress water leakage.

である。(Means for Solving the Problems) The elastic pipe joint of this invention for achieving the above object is characterized in that a large number of protrusions extending in the axial direction are provided radially on the outer circumferential surface of at least both ends. It is something.
（作 用）

て締付けると、各突条の頂部に締付荷重が集中
し、該突条が半径方向に大きく弾性変形するの
で、液密性が高められる。(Function) During construction, when the pipes to be joined are inserted into both ends of the pipe joint, and a tightening band is wrapped around them and tightened, the tightening load is concentrated on the top of each protrusion, causing the protrusion to tighten. is largely elastically deformed in the radial direction, improving liquid tightness.
（実施例）
第１〜３図に示すように管継手１は従来と同様

いる。(Example) As shown in Figs. 1 to 3, the pipe joint 1 is made of an elastic material such as rubber as in the past, but in this invention, a large number of radially extending protrusions 2 extending in the axial direction are provided on the outer peripheral surface. ing. The protrusion 2 is provided over the entire length between both end faces of the pipe joint 1, and its cross-sectional profile is parabolic, and the space between adjacent protrusions 2 is a curved surface.
この管継手１は施工時において、従来と同様に
両端部に管１２，１３が嵌入され、締付バンド１

１３の外周面に密着し、液密性が高められる。 At the time of construction, this pipe joint 1 has pipes 12 and 13 fitted at both ends as in the conventional case, and a tightening band 1.
4 and bolts and nuts 15. At that time, the tightening load will be concentrated on the top of each protrusion 2, and each protrusion 2 will be largely elastically deformed in the radial direction, causing the inner circumferential surface of the pipe fitting 1 to
13 and improves liquid tightness.

に切断して装着できるという利点がある。 In order to improve the liquid tightness at the joint and reliably prevent water leakage, it is sufficient to provide the protrusions 2 on both ends of the pipe joint 1. It is preferable to provide it over the entire interval. That is, by doing as described above, there is an advantage that the strength against bending can be increased compared to the conventional one shown in FIG. 5, and that it can be cut to the required length and installed at the construction site.

In addition, the cross-sectional outline of the protrusion 4 is arcuate,
The adjacent protrusions 2 are continuous without being curved. In this case, cloth or the like may be embedded inside.
