Description

Water and sewage pipe connectivity french}

The present invention relates to a water supply and sewage pipe that can be connected to the French, and more specifically, to supply a predetermined width by impregnating the resin by supplying the yarn and resin continuously, after processing the high-strength French to connect the water and sewage pipe stably and firmly. It relates to a French connectable water and sewage pipe, characterized in that to enable the French connection.

In general, the sewer pipe has a double wall sewer pipe or a double wall sewer pipe which is formed by extruding a profile in which a reinforcing bar having a rectangular or cross shape is formed in a spiral shape and spirally wound. There was a double-walled tube 10 in which the inner diameter tube 13 was extruded into the inner diameter while continuously forming).

The double-walled tube is formed by continuously forming a groove part and a protrusion part by a mold that is bisected into a strip in a process of melting and supplying the raw material supplied from the extruder, and extruding the inner tube by the inner diameter of the groove part and the protrusion part. The groove is connected to the outer diameter of the double wall to be molded.

Such a conventional technique is to cut a double wall pipe into a predetermined length and supply it to the expansion pipe coalescence and powder mold as invented in Korean Patent No. 0438324 (registered on November 15, 2004) to expand the tip portion to form a socket part. In this case, the packing is coupled to the groove of the expansion part so as to be connected to the socket.

However, this conventional technology produces a double-walled tube, cuts it to a predetermined length, and supplies it to a separate expansion coaling and powder mold to separately expand the process by heating the tip portion, thereby minimizing and completing facility costs and expansion time. As the double walled pipe was separately expanded, the expansion was not performed normally, and the defects increased, and the work was very difficult, and the defects occurred due to the forced expansion of the molded material by heating again.

And Utility Model Registration No. 0296549 (Registered on Nov. 18, 2002) installs a ring-shaped packing at the tip of double wall pipe and separates the outer wall of the inclined ring by pressing the outer surface of the ring-shaped protrusion. Since the fastening using the structure of, because of the need to provide a tightening structure to maintain the watertight by connecting a separate double wall pipe was difficult in the separate production and connection work of the fastener.

In addition, Invention Patent No. 0716063 (2007. 05. 02. registration) is formed by the operation of connecting a separate connector to the end of the sewage pipe to form a single pipe after connecting the sewer pipe on the other side, so the separate connector It is produced through the process of molding and fusion of the produced connector to the end of the sewer pipe through a separate process, so that labor costs by separate manufacturing process and space and work difficulty through independent work are generated. There was a flaw.

After injection molding of various structures using synthetic resin, the French is connected to the tip of water and sewage pipe, and then fused by using molten synthetic resin and then connected by using bolts and nuts in French. The connection part of the water supply and sewage pipe is very fragile, and there is a drawback that the sewage pipe or the French are easily separated even if the load is applied.

Document 1. Invention Patent No. 0438324 (registered Nov. 15, 2004) Document 2. Utility Model Registration No. 0296549 (registered Nov. 18, 2002) Document 3. Invention Patent No. 0716063 (registered May 05, 2007) Document 4. Utility Model Registration No. 3003018 (registered on Jan. 17, 2003)

Therefore, the present invention has been made to solve the above-mentioned drawbacks, and to supply a fiber glass fabric impregnated in the resin and then wound in a rotating mold to form a trench to have a predetermined shape with the water supply and drainage pipe connecting groove. It is done.

The object of the present invention is to connect the water and sewage pipes in the connection groove of the molded French to connect the French and water and sewage pipes in the connection groove using an epoxy adhesive.

The present invention provides a Hurenji molding apparatus for manufacturing the French so that the strength is greatly improved to provide a connection groove that can be connected to the water supply and sewage pipes by supplying the fiberglass fabric impregnated into the resin and then powering the rotating mold. For the purpose.

The present invention connects the trench formed with a plurality of through-holes on both ends of the water and sewage pipes, the packing is installed between the trenches and through the through-holes through the bolts in the water and sewage pipes coupled to the nut,

A flange formed by connecting both ends of the water and sewage pipes, respectively, and supplying fiberglass yarns with a predetermined width to impregnate the resin, and then winding the rotating mold;

It is characterized in that made by fixing the epoxy adhesive by coupling the water and sewage pipe to the connection groove formed on one side of the hole of the French.

The present invention is to provide a glass to provide a fiber glass fabric impregnated in the resin and then wound in a rotating mold to form a trench to have a predetermined shape with the water supply and drainage pipe connecting groove.

The present invention is to connect the water and sewage pipes in the connection groove of the molded French to enable the connection between the French and the water and sewage pipe in the connection groove using the epoxy adhesive.
