法に関する。Detailed Description of the Invention [Field of Industrial Application] The present invention is directed to a hose having a corrugated outer peripheral wall in the axial direction. and fitting a metal cylindrical member externally and internally fitting a metal cylindrical pipe joint member to the end of the hose around which the spiral steel material is wound,
The present invention relates to a method for connecting a hose and a pipe joint member, in which the diameter of the pipe joint member is expanded and the end portion of the hose is clamped between the cylinder member and the pipe joint member via the spiral steel member.
従来、上記接続方法では、ホース端部と筒部材
とは、ホース端部の外周壁に巻付けた螺旋状鋼材
を介して、摩擦力によつてのみ相互に抜け止め保
持してあつた。
Conventionally, in the above-mentioned connection method, the hose end and the cylindrical member were held together against each other only by frictional force via a spiral steel material wrapped around the outer circumferential wall of the hose end.
しかし、螺旋状鋼材と筒部材とは、いずれも金

た。
However, since the spiral steel material and the cylindrical member are both made of metal, the frictional force between them is weak, causing slippage and the cylindrical member coming off the hose end, causing the pipe joint member and the hose end to slip. There was a risk that the pressure force would weaken and the hose would separate from the pipe joint member.
本発明の目的は、ホース端部から筒部材が抜け
にくくなるようにする点にある。 An object of the present invention is to make it difficult for the cylindrical member to come off from the end of the hose.

The characteristic means of the method for connecting a hose and a pipe joint member in the present invention is that before the pipe joint member is deformed to expand its diameter, an adhesive is filled between the cylindrical member and the outer peripheral wall, and the pipe joint member is expanded in diameter. The purpose is to harden the adhesive after deforming, and its effects are as follows.
つまり、筒部材と外周壁との間に接着剤を充填
することによつて、螺旋状鋼材に対して外周壁及
び筒部材が接着し、ホース端部と筒部材とは摩擦

固に抜け止め保持される。
In other words, by filling the gap between the cylindrical member and the outer circumferential wall with adhesive, the outer circumferential wall and the cylindrical member adhere to the spiral steel material, and the hose end and the cylindrical member are not only bonded by friction but also bonded. The adhesive force of the agent also ensures that it does not come off and is held firmly.
従つて、ホース端部から筒部材がより抜けにく
くなり、管継手部材とホース端部との圧接力を強
く保ちながら、ホースと管継手部材との接続状態
を良好に維持できるようになつた。
Therefore, it becomes more difficult for the cylindrical member to come off from the end of the hose, and it becomes possible to maintain a good connection between the hose and the pipe joint while maintaining a strong pressure contact between the pipe joint and the end of the hose.
その上、前記接着剤は、管継手部材を拡径変形

筒部材と外周壁との接着作用を、より効果的で強

至つた。 Furthermore, since the adhesive is filled before the pipe fitting member is expanded in diameter and cured after the pipe fitting member is expanded in diameter, the adhesive is applied in a spiral shape when the pipe fitting member is expanded in diameter. It can sufficiently penetrate into small gaps between the steel material, the cylindrical member, and the outer peripheral wall, and the adhesive action between the cylindrical member and the outer peripheral wall via the spiral steel material can be made more effective and strong, and the hose and pipe joint member as a whole can be improved. It has now become possible to reliably maintain a connection with the network over a long period of time.
