  • Patent number: 8387893
    Abstract: A structure of a dry heating system, and a method for constructing the same are disclosed. An upper board stacked on a heat radiator has a double-layer structure comprising first upper board elements and second upper board elements in order to prevent steps from being formed at seaming portions formed on the upper portion of the dry heating system, thereby maintaining flatness of the upper board, and reducing any bending of the upper board, in which the first upper board elements constitute a lower portion of the double-layer structure, and serve to protect the heat radiator while supporting a weight load, and the second upper board elements constitute an upper portion of the double-layer structure, and serve to maintain the flatness of the upper board by removing the steps, thereby ensuring excellent quality in construction of the dry heating system.

  • Patent number: 7594365
    Abstract: Disclosed herein is a floor sound-insulating type heating system in which a floor sound-insulating structure for reducing the transmission of an impact sound from upstairs to downstairs in an apartment complex and a dry floor heating structure are integrally formed with each other. The floor sound-insulating type heating system can achieve improvements in construction efficiency as well as sound insulation and heat insulation effects.

  • Patent number: 7493692
    Abstract: Disclosed herein is a method for manufacturing a heating panel. The method comprises preparing upper and lower moulds corresponding to the upper and lower plates, injecting a plastic material into the moulds to produce semi-manufactured products of the upper and lower plates, and bonding the semi-manufactured products of the upper and lower plates to produce the heating panel. The heating panel comprises a uniform fluid pathway formed therein, and allows uniform flow of heating fluid. The heating panel is manufactured by injection molding, thereby preventing blockage of the heating panel to ensure uniform flow of heating fluid. In addition, since the upper and lower plates are formed to a uniform thickness by injection molding, the method of the present invention enables precise forming of the heating panel, thereby allowing a constant tolerance and high quality of the heating panel.

  • Patent number: 7404432
    Abstract: Disclosed is a plate-shaped heating panel having connecting members fastened to each other by means of resin. The heating panel comprises upper and lower plates integrally formed to face each other so as to form an inner fluid pathway in which heating water flows, a plurality of connecting members, each symmetrically extending from the upper and lower plates toward the lower and upper plates, respectively, and connecting the upper and lower plates to each other, the plurality of connecting members forming the inner fluid pathway at an inside surface of the plate, and two fluid communication portions for supplying and discharging the heating water, wherein one or more connecting members adjacent to the fluid communication portions are punctured to form holes. The holes are filled with a melted plastic resin, and the integrated plastic resin is integrated with the connecting members by pressing.

  • Patent number: 7027725
    Abstract: Disclosed herein is a heating system of floating floor structure including a heating panel with a circular or elliptical inner fluid pathway. The heating panel having the circular or elliptical inner fluid pathway overcomes limitation on pressure resistance, which is the problem of the convention heating panel having a hexagonal fluid pathway, thereby providing enhanced pressure resistance. Furthermore, a floating floor structure of the heating system enhances thermal efficiency, and effectively improves sound absorbing/dampening function in a floor of a building. Additionally, the floating floor structure is provided with inner spaces, which allow utility equipment, such as an electric wire or a pipe, to be easily established therein, thereby enabling an easy repair of the heating system and the utility equipment.
