<P>PROBLEM TO BE SOLVED: To provide a caulking auxiliary member which is compatible to piping members of different diameters, easily constructed, and surely suppresses filling of caulking agents more than necessary into a sleeve. <P>SOLUTION: A sleeve 3 is buried through a concrete layer constituting the foundation of a building so as to be opened inside/outside the building, a piping member 2 constituting at least a part of a piping path inside/outside the building is used for a piping structure inserted into the sleeve 3. At the end of the sleeve 3 outside the building, a caulking auxiliary member 1a is disposed so as to bury a space between the sleeve 3 and the piping member 2, and is filled into the space between the sleeve 3 and the piping member 2 from the end of the sleeve 3 outside the building. The caulking auxiliary member 1a is made of an elastic resin foam, usable for a plurality of piping members of different outer diameters, and formed into a cylindrical shape in which an inner peripheral diameter is increased from one end to the other in a tapered fashion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
