SOUND- AND HEAT-INSULATED HEATED FLOOR Russian patent published in 2003 - IPC

FIELD: heating systems for dwelling spaces. SUBSTANCE: proposed heated floor is assembled from plastic profiled panels each of which is provided with hollow bearing projections and fasteners on panel of heating tubes. Cavity of bearing projections is filled with cement mortar forming heated floor after hardening. Each profiled panel is square in shape. Each bearing projection is provided with 1 to 3 bearing tenons. Sites formed between open ends of adjacent projections have areas with weakened section for mounting heating tube locking devices made in form of clamps with piercing legs. Panel is provided with connecting flanges; flanges on both adjacent sides of panel are made below two other adjacent opposite flanges by thickness of flanges located higher; flanges located below have holes and flanges located higher are provided with connecting pegs directed downward; said pegs are received by holes of flanges located below. Side walls of panel under flanges are inclined inside panel at angle relative to vertical of 5 to 15 deg. Located under profiled panel is heat-insulating panel made form foam plastic, foam polystyrene, for example. Thickness of heat-insulating panel is lesser than height of bearing projections of profiled panel; heat-insulating panel is fitted on these projections forming air gap between heat-insulating panel and sections of profiled panel between bearing projections. Panel assembly is mounted on base of floor on bearing tenons for taking weight of section of floor formed from cement mortar and heating tubes. EFFECT: improved sound- and heat-insulation; enhanced smoothness of heating due to rational laying of tubes. 3 dwg
