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.

Disclosed herein is a floor system for efficiently absorbing an impact applied to a floor. The floor system includes a first impact-absorbing material, and a second impact-absorbing material installed at an upper side of the first impact-absorbing material and having a higher density than that of the first impact-absorbing material.

Floor system

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.

Heating floor system

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.
