The present invention relates to a prefabricated panel structure for a hot water heating to fixate pipes for the hot water heating using a connection coupler. A dry panel of the prefabricated panel structure comprises a panel upper plate, an insulator to contain the pipe, an insulation sheet, a damp-proof sheet and a panel lower plate on which an additional sound-proof material can be attached. The present invention has an advantage of reducing noises between floors using the sound-proof material provided on the dry panel, with an improved compatibility in connecting pipes by retaining existing hot water pipes. Furthermore, the connection coupler is provided to fixate the hot water pipe and the pipe by changing a shape of a first coupling ring, with an advantage of ensuring the fixating force without damaging the hot water pipe and the pipe, to improve the durability and the sealing property. |
