The invention discloses a dry-method heating cable mounted structure comprising a heating cable and a dry-method mounted floor. The dry-method mounted floor comprises an EPS insulation board, a heat conductive aluminum film, an aluminum foil tape and a heating floor. A mounting groove used for mounting the heating cable is formed on the surface of the EPS insulation board, the heat conductive aluminum film is paved on the upper surface of the EPS insulation board, the heating cable is located above the heat conductive aluminum film and in the mounting groove, the aluminum foil tape is sticked above the heating cable and the heat conductive aluminum film and is used for fixing the heating cable, and the heating floor is located above the aluminum foil tape. By the aid of the dry-method heating cable mounted structure, the problems of irregularity and unexpected effect in the existing heating cable floor heating dry-method mounting process are overcome, the mounting method is regular, accordingly the heating cable floor heating is safer, more effective and convenient and rapid to mount.
