Description

Junction pipe for synthetic resins pipe

The present invention relates to a branch joint pipe for a synthetic resin pipe, and in particular, a branch joint for a synthetic resin pipe which can be easily coupled to a branch pipe connection part of a synthetic resin pipe by attaching a heating wire to a part or the whole of the joint integrally with the thermal connection of the branch pipe. It's about the coffin.

In general, synthetic resin pipes commonly used in sewage pipes have to be produced in a certain unit length due to the constraints of manufacturing and transportation. Actually, sewage pipes buried underground have a very long length, so many synthetic resin pipes are connected and installed in the field. It is already well known.

And, it is necessary to additionally connect a separate branch pipe to the pre-installed synthetic resin bar, conventionally tee type joint pipe having the same branch diameter between the two synthetic resin pipes in order to connect the branch pipe to the pre-installed synthetic resin pipe in the field It was constructed by connecting two synthetic resin pipes and branch pipes at the same time by using Lee Kyung-Tee joint pipe.

However, the method as described above has a disadvantage in that the construction cost is not only high, but the synthetic resin tube is cut or a short length synthetic resin tube must be used.

Therefore, in order to use the method of simply joining the joints of the branch pipes in the state of drilling holes for joining the branch pipes to the synthetic resin pipe, a polyethylene sheet is produced while inserting a hot wire, which has a high resistance, to supply power to the sheet. While the method by electrofusion to melt the polyethylene sheet by the heat generated from the heating wire to join the pipe was proposed and used in part, the connection part of the branch pipe was manufactured by joining by fusion welding.

However, according to the conventional method of joining the branch pipe by the electrofusion as described above, since the heating wire must be embedded in the polyethylene sheet, the manufacturing is complicated and its own weight increases, making it difficult to transport and install.

Therefore, the applicant of the present invention has submitted a patent application 2001-46450 (name: branch joint pipe for synthetic resin pipe) to solve the problems as described above.

The conventional branched joint pipe for synthetic resin pipes as described above, in the branched pipe for synthetic resin pipe connecting the branch pipe to the synthetic resin pipe, the junction portion of a larger area than the portion to be connected to the synthetic resin pipe integrally formed in the branch pipe, It is a structure characterized in that the terminal line is exposed to the outside while the planar heating element made of carbon material is attached to a part of the inner surface of the joint surface of the engine.

However, the conventional joint pipe for the synthetic resin pipe as described above is provided with a planar heating element at the junction of one side of the tube when connecting the synthetic resin tube, the planar heating element is the end of the both ends of the synthetic resin tube when the electric current is supplied to the planar heating element using a terminal line At this time, the planar heating element has a problem that the heat generation is not uniformly generated, the heat generated unevenly.

That is, when the branch pipe is connected by using the conventional planar heating element as described above, the end of the branch tube fitted to the end of the synthetic resin tube also differs depending on the degree of heat generation of the planar heating element due to uneven heat generation of the planar heating element. As a result, when the branch pipe is connected to the synthetic resin pipe, deformation occurs at the connection part, causing a problem that the connection part is lifted up between the synthetic resin pipe.

Accordingly, the present invention has been devised to solve the problems described above, by attaching a hot wire to a part or the whole of the joint integrally formed in the connection portion of the branch pipe, the branch pipe connecting portion of the synthetic resin pipe simply It is an object of the present invention to provide a branch joint pipe for a synthetic resin pipe which can be combined.

Branched joint pipe for a synthetic resin pipe according to the present invention for achieving the above object is a branch pipe for a synthetic resin pipe connecting the branch pipe to the synthetic resin pipe, the branch pipe formed integrally with the junction of a larger area than the connection portion to the synthetic resin pipe and; A hot wire attached to an inner surface of the junction surface of the branch pipe and formed of one meandering line and disposed on the same plane at equal intervals; The terminal wire is connected to the hot wire and is configured to be exposed to the outside.
