Abstract

<P>PROBLEM TO BE SOLVED: To provide a header made of resin provided with a plurality of branched pipes in which a manufacture is simple, inner and outer diameters are uniform in a longitudinal direction and a length is abundant; and a header construction method using it. <P>SOLUTION: It the header made of resin, one end part of the branched pipe 12 comprising cross-linked polyethylene is inserted to a rotation fusion receiving ports 112 of a header body 1 comprising cross-linked polyethylene and having the rotation fusion receiving ports 112 through a cylindrical body 13 comprising cross-linked polyethylene. An outer surface of the cylindrical body 13 and an inner surface of the rotation fusion receiving ports 112; and an inner surface of the cylindrical body 13 and an outer surface of the branched pipes 12 are fused by a rotation friction fusion utilizing a heat generation caused by a circumferential rotation of the cylindrical body 13. <P>COPYRIGHT: (C)2003,JPO

Water was used by connecting the connection fittings by screwing in to stop water.

ものが考えられる。In such a conventional metal header, it is very troublesome to form a screw hole in the header body, which is costly and heavy. In addition, the connection work of screwing the connection fitting into each screw hole was complicated.
In addition, the reliability of the threaded portion is becoming a problem, and a connection method that does not rely on the resin header and the screw method is required. As such a resin header, a header body in which a plurality of branch pipes are integrally provided is considered.

なす必要がある。When an injection molding method which is usually used for resin molding is adopted as a method of manufacturing this resin header, there is a restriction of demolding from the mold, and as shown in FIG.
When the length L1 of the branch pipe a is shortened to a resin header A or the length L2 of the branch pipe b is increased as shown in FIG. 8, it is easy to remove from the mold. Therefore, it is necessary to form the outer surface of the branch pipe b into a resin header B having a draft.

つなぎなおしを行う必要が生ずるという問題点がある。When the resin header A shown in FIG. 7 is used to connect the resin pipes, the length L1 of each branch pipe a is fully used to secure the strength of the connection portion. Although it is necessary to connect the resin pipe with a pipe joint such as a resin socket of the type, in many cases, once it is connected, the connection structure will not be detachable, so some resin pipes may have troubles such as pipe rupture. When it occurs, since the full length L1 has been used for the branch pipe a, repair is performed by disconnecting only the root portion of the branch pipe a to which the resin pipe is connected and reconnecting with a new pipe joint. However, there is a problem in that it is necessary to perform reconnection such that the entire resin header A is replaced.
