Abstract

Abstract A plate on which pipes of a floor heating system can be installed includes an abrasion-proof molded cover foil of relatively tough synthetic material and an insulation sheet of synthetic foam material, arranged below the cover foil, whereby the cover foil contains holding devices, molded in one piece as clamping fingers projecting from the foil material, for securing the pipes of the heating system. The insulation sheet is provided with protruding plugs which can be inserted into the hollow clamping devices of the cover foil, whereby the cover foil and insulation sheet are held together at least temporarily. There is also provided ribs for stiffening backs of the clamping fingers.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 142 words
A plate for the assembly of a floor covering on which pipes of a floor heating system can be installed, comprising: an abrasion-proof molded cover foil of relatively tough synthetic material, said cover foil having a plurality of equispaced one-piece molded hollow holding devices, each formed with four upwardly projecting and opposing clamping fingers, for securing the pipes therebetween, said clamping fingers having ribs formed on outer sides thereof for stiffening backs of said clamping fingers, and an insulation sheet of synthetic foam material installed directly under the cover foil, said insulation sheet having protruding insertion parts which can be inserted into the hollow holding devices of the cover foil, whereby the cover foil and the insulation sheet are at least held together provisionally by inserting the insertion parts of the insulation sheet into the hollow holding devices of the cover foil.
Claim 2
Dependent Claim 142 words
A plate for the assembly of a floor covering on which pipes of a floor heating system can be installed, comprising: an abrasion-proof molded cover foil of relatively tough synthetic material, said cover foil having a plurality of equispaced one-piece molded hollow holding devices, each formed with four upwardly projecting and opposing clamping fingers, for securing the pipes therebetween, said clamping fingers having ribs formed on outer sides thereof for stiffening backs of said clamping fingers, and an insulation sheet of synthetic foam material installed directly under the cover foil, said insulation sheet having protruding insertion parts which can be inserted into the hollow holding devices of the cover foil, whereby the cover foil and the insulation sheet are at least held together provisionally by inserting the insertion parts of the insulation sheet into the hollow holding devices of the cover foil.
Claim 3
Dependent Claim 36 words
A plate according to claim 1, wherein said clamping fingers are symmetrically distributed around a center point and each permits a clamping between itself and an opposing clamping finger or between itself and a center rest.
Claim 4
Dependent Claim 36 words
A plate according to claim 1, wherein said holding devices on the cover foil are arranged in a square grid with a given side length and with sides running parallel to sides of the cover foil.
Claim 5
Dependent Claim 36 words
A plate according to claim 2, wherein said holding devices on the cover foil are arranged in a square grid with a given side length and with sides running parallel to sides of the cover foil.
Claim 6
Dependent Claim 37 words
A plate according to claim 2, wherein protruding surfaces of the holding devices, in the clamping direction, contain, as seen in a plan view, only up to 20% of a total projection surface of the holding devices.
Claim 7
Dependent Claim 18 words
A plate according to claim 1, wherein sides of the plate are provided with a flexible sealing strip.
Claim 8
Dependent Claim 21 words
A plate according to claim 6, wherein the sealing strip contains a perforation arrangement matching a configuration of the holding devices.
Claim 9
Dependent Claim 28 words
A plate according to claim 3, wherein the cover foil is formed to have an arrangement of equidistant grooves, intersecting at right angles, which form a square grid.
Claim 10
Dependent Claim 28 words
A plate according to claim 4, wherein the cover foil is formed to have an arrangement of equidistant grooves, intersecting at right angles, which form a square grid.
Claim 11
Dependent Claim 20 words
A plate according to claim 3, wherein the holding devices are distributed on the square grid in a chessboard manner.
