<P>PROBLEM TO BE SOLVED: To easily lay a resin pipe by smoothly moving an end jig on a slab and surely moving it to a destination position while easily riding over the other structure when abutting thereon. <P>SOLUTION: The end jig 1 for the resin pipe is mounted at the front end of the resin pipe when laid in an underfloor space between the slab and a floor in a multiple dwelling house. The end jig includes a number of needle protrusions 3 formed on the outer peripheral face of a streamline-shaped body 2 having an outer diameter larger than the outer diameter of the resin pipe P. Thus, when the end jig 1 is mounted at the front end of the resin pipe P and delivered into the underfloor space through an opening of the floor, the end jig 1 whose number of needle protrusions 3 are elastically deformed to support the body 2 in a floating state is moved on the slab to rub thereon in this state, and thereby the end jig 1 can be smoothly moved while minimizing friction resistance. When abutting on the other structure, the end jig whose needle protrusions 3 are further elastically deformed can easily ride over the other structure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
