用する管の接続方法に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of connecting pipes, particularly synthetic resin pipes, which are used for connecting a synthetic resin pipe through a rubber ring by a receiving / inserting method.

緩和してゴム輪の離脱防止,損傷防止を図っている。In this pipe connecting portion, in order to give flexibility, the insertion opening can be tilted to a certain extent with the rubber ring as a fulcrum in the receiving opening. In the above-mentioned pipe connection, when the pipe insertion port is inserted into the pipe receiving port, the tip of the insertion port hits the rubber ring, and a pressing force in the pipe axis direction acts on the rubber ring. Therefore, in order to impart the above flexibility, the gap between the pipe receiving port and the pipe inserting port is considerably widened, and accordingly, the protruding height of the rubber ring from the inner surface of the pipe receiving port is also increased. Since there is a concern that the rubber ring may be detached or damaged by the pipe axial pressing force, conventionally, the tip outer peripheral portion of the pipe insertion opening is chamfered to ease the pipe axial pressing force and release the rubber ring. Preventing and preventing damage.

かれて、ゴム輪の離脱,損傷が惹起され易い。However, the chamfering work of the pipe insertion port must be carried out after the continuous cutting of the continuously extruded pipe while maintaining the cooperation with the forming process of the pipe receiving port. It is not easy because it needs to be done at high speed.
Further, the chamfering of the pipe insertion port is usually performed by cutting, and the cutting surface is likely to be roughened due to the above high-speed processing, or the chamfered portion is likely to be damaged due to its thin wall during transportation of the pipe. The rubber ring is scratched due to a rough surface or a defective edge, and the rubber ring is likely to be detached or damaged.

らつき、信頼性に問題がある。In addition, a fixed length pipe is often cut and used as appropriate in order to adjust the length of the pipe line during construction. In this case, the cut pipe end must be chamfered at the construction site. However, the chamfering work at the construction site is not only a complicated work, but the chamfering amount also varies depending on the operator, etc., and there is a problem in reliability.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a pipe connecting method capable of reliably preventing damage and easily inserting the pipe insertion port into the pipe receiving port.

ができる。The pipe connecting method of the present invention has the construction as described above, and the insert having the tapered taper portion is pushed into the pipe receiving port by the pipe insertion port, and the taper of the insert is tapered. -Because the rubber insert in the pipe receiving part is expanded in the pipe part while inserting the pipe insertion port, the pressing force in the pipe axial direction acting on the rubber ring is due to the gentle inclination of the taper taper part. It can be made small enough to prevent the rubber ring from coming off. Further, since the tip of the tube insertion port does not come into contact with the rubber ring and the shape of the tip of the tube insertion port can be arbitrarily set, chamfering of the outer peripheral portion of the tip of the tube insertion port can be omitted, and the extruded tubular body It is possible to simplify the manufacturing process of the pipe by forming the pipe body after the standard length cut only by forming the receiving port, or during transportation of the pipe, connect the pipe even if a defect occurs in the pipe insertion port. It can be performed without any trouble, and the work of chamfering the cut pipe end can be omitted at the construction site.
