PROBLEM TO BE SOLVED: To solve the problem that construction work performance becomes worse because the condition of attachment of underfloor piping, rising on a floor surface, to a socket becomes bad depending on the dimensional accuracy of floor piping connected to the socket and having a piping opening positioned above a floor, or the construction accuracy of a rising position of the underfloor piping rising on a floor surface, in a water-distribution connecting structure technology. SOLUTION: In this piping connecting structure, the underfloor piping rising on the floor surface, and the floor piping having the piping opening positioned above the floor are connected together. The piping connecting structure comprises: a cylindrical adapter which is connected to the underfloor piping; the socket which is connected to the piping opening of the floor piping and connected to the adapter via an adapter connecting portion; and a sealant which is interposed between the adapter and the socket, so as to maintain water-tightness. A part of an outer peripheral surface of the adapter is equipped with a flange portion; and the adapter connecting portion of the socket is equipped with a floor abutting surface which is brought into contact with a floor surface, a sealant receiving surface which is formed inside the floor abutting surface, and a water distribution opening which is formed inside the sealant receiving surface. When the socket and the adapter are connected together, a gap is provided between the floor abutting surface of the socket and the flange portion of the adapter. COPYRIGHT: (C)2010,JPO&INPIT |
