ELECTRICAL MELTED TYPE CONNECTION CAPABLE OF ENDURING AGAINST THE DIFFERENTIAL SETTLEMENT OF SOFT GROUND OR THE EARTHQUAKE

摘要

PURPOSE: An electrical melted type connection is provided to effectively cope with the differential settlement of soft ground or the earthquake by compressing an elastomeric packing installed in a groove of the outer slope of an electrical melted packing to an inclined packing melted part of a cylindrical socket and electrically melting the inside in which an electric heating line is embedded with the outer circumference of a synthetic resin pipe.;CONSTITUTION: An electrical melted type connection is composed of a cylindrical socket(110), an electrical melted packing(210), and a pusher(220). A projection(111) is formed in the inner surface of the cylindrical socket. An inclined packing part(112) is formed at the inlet of the cylindrical socket. A hanging projection(113) is formed in the outer circumference of the cylindrical socket. An elastomeric packing(212) is installed in a groove(211) formed in the upper slope of the electrical melted packing. An electric heating line(214) having a terminal(213) is embedded in the lower part of the electrical melted packing. A fastening hole(222) is formed on an outer circumference cover(221) of the pusher. A pushing projection is formed within the inner surface of the pusher.;COPYRIGHT KIPO 2010
