A spacer plate for use in making a hollow floor has a plurality of truncated cone-shaped spacer elements extending from one side of the plate, and distributed in a row wise and column wise arrangement, for supporting the spacer plate from an underfloor, and also formed in the spacer plate are grooves formed in the same side of the plate as the spacer elements for holding a pipe conducting a heating or cooling medium, with the grooves surrounding at least a half of the circumference of the pipe to securely hold the pipe in place on the plate, so that the heating or cooling medium conducted through the pipe can come into heat exchange relationship not only with an upper floor laid on top of the spacer plate but also with air conducted through space existing between the spacer plate and the underfloor.

1. A spacer plate for a hollow floor, said spacer plate having a surface and a plurality of spacer elements distributed over the surface for engagement with an underfloor (24) and a holding element (16, 18, 20) for holding a pipe (22) for a heating or cooling medium, wherein: the spacer elements are formed by truncated cone-shaped protrusions (14) extending away from one side of the spacer plate, and the holding elements are formed by grooves (16, 18, 20) which are formed in the spacer plate (20) on the same side of the plate as the protrusions (14), which grooves surround the pipe to be placed in the grooves by at least a half of the circumference of the pipes, wherein the protrusions (14) are arranged equidistantly in rows and columns and wherein the grooves (16) extend column wise and row wise transversely over the protrusions. 2. A spacer plate according to claim 1 wherein further grooves (18) are provided, which further grooves extend diagonally to the column wise and row wise oriented grooves (16). 3. A spacer plate according to claim 1 wherein between each four protrusions (14) a circular shaped groove (20) is formed which circular shaped groove coincides at least partially between each two protrusions (14) with the column and row wise oriented grooves (16).
