A composite floor heating plate

The utility model relates to terrestrial heat technology, in particular to a composite terrestrial heat board for laying terrestrial heat pipes, composed of three spliced layers of massive structures. The upper layer is a pulverized ash cement foam plate, the middle layer is a fiberglass enhancement cloth layer and the lower layer is a polystyrene plate. The pulverized ash cement foam plate is in a cellular structure provided with holes and is provided with a walk tube flute at the surface; the fiberglass enhancement cloth plate in the middle is in a reticulate structure; the upper surface of the polystyrene plate is provided with a dovetail slot. The fiberglass enhancement cloth plate and the polystyrene plate are fixed together through the dovetail slot. With simple structure, the utility model is easy to be laid, saving time and labor and improving construction efficiency. Strong in intensity, light in weight, and good in heat preservation and insulation performance, the utility model can eradiate heat to places which are in need of heat, and is environment friendly and can save energy. The utility model has good functions of shock absorption and sound insulation, and the property of corrosion resistance and aging resistance, with on radiological hazard and environment pollution. The terrestrial heat pipes are convenient to maintain and to change.
