Hard foam support plate for holding the heating pipes of a floor heating system and tool for incorporating the laying channel and method for laying heating pipes in the rigid foam support plate

摘要

Hard foam support plate with one or more incorporated or molded, the plate top open towards channels (1) for receiving the heating tubes (3) of a floor heating. The channels (1) have a width greater than the diameter of the heating pipes (3) to be laid therein and the channels (1) meander around a laying center line, so that heating pipes laid in the channels alternately come to rest on opposite side walls of the channels. The remaining spaces between channels (1) and heating pipes (3) are filled with a good heat-conductive filler or dergleich. For cutting the channels (1) in the hard foam support plate (4) a tool is provided with a hollow knife (9) in the form of the cross-sectional contour of the cut-in channel (1), which hollow knife (9) on the underside of a sliding plate (6). is arranged for sliding on the top plate when cutting the channel. The slide plate (6) has a receptacle (5) for connecting the tool to an oscillating hand-held device.
