Abstract
Abstract A double floor with framed floor plates of heat-conductive and/or heat storage materials, particularly a mineral material such as anhydrite in a metal vat-shaped outer armature. A system of pipes carrying a heating or cooling medium is held in heat-conductive contact with the bottom surfaces of the framed floor plates.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
122 words
In a double floor with framed floor plates of a heat conductive or heat storage material, the improvement comprising a system of pipes for carrying a heating or cooling medium, holding and fixation elements supporting said pipes, and upright bearings supporting the floor plates and also supporting said holding and fixation elements to maintain said system of pipes in heat-conductive contact with the bottom surfaces of the floor plates, said upright bearings having support plates movably mounted thereon for vertical adjustment, and said holding and fixation elements being mounted on said support plates, whereby the height of said holding and fixation elements can be adjusted to vary the force of contact of said pipes with the bottom surfaces of the floor plates.
Claim 2
Dependent Claim
122 words
In a double floor with framed floor plates of a heat conductive or heat storage material, the improvement comprising a system of pipes for carrying a heating or cooling medium, holding and fixation elements supporting said pipes, and upright bearings supporting the floor plates and also supporting said holding and fixation elements to maintain said system of pipes in heat-conductive contact with the bottom surfaces of the floor plates, said upright bearings having support plates movably mounted thereon for vertical adjustment, and said holding and fixation elements being mounted on said support plates, whereby the height of said holding and fixation elements can be adjusted to vary the force of contact of said pipes with the bottom surfaces of the floor plates.
Claim 3
Dependent Claim
21 words
A double floor as in claim 1, characterized in that pipes are held in a laminar contact with the floor plates.
Claim 4
Dependent Claim
45 words
A double floor as in claim 1, characterized in that said holding and fixation elements are provided with grooves for the pipes, are curved upwardly from their mounting positions against the bottom surfaces of the floor plates, and are formed of an elastically flexible material.
Claim 5
Dependent Claim
27 words
A double floor as in claim 3, characterized in that holding and fixation elements for the pipes are formed by plate-shaped structural elements of a heat-insulating material.
Claim 6
Dependent Claim
27 words
A double floor as in claim 1, characterized in that holding and fixation elements for the pipes are formed by plate-shaped structural elements of a heat-insulating material.
Claim 7
Dependent Claim
27 words
A double floor as in claim 4, characterized in that the tops of the plate-shaped holding and fixation elements are provided with a heat radiation reflecting sheet.
Claim 8
Dependent Claim
63 words
A double floor as in claim 3, characterized in that holding and fixation elements for the the pipes comprise bars, and the pipes between these bars are supported by an elastically flexible insulation material filling in the hollow space disposed beneath the double floor and against the floor plates, whereby the insulation material filler is packed by the weight of the floor plates.
Claim 9
Dependent Claim
62 words
A double floor as in claim 1, characterized in that holding and fixation elements for the pipes comprise bars, and the pipes between these bars are supported by an elastically flexible insulation material filling in the hollow space disposed beneath the double floor and against the floor plates, whereby the insulation material filler is packed by the weight of the floor plates.
Claim 10
Dependent Claim
24 words
A double floor as in claim 1, characterized in that the floor plates are sealed on their edges to hold back rising warm air.
Claim 11
Dependent Claim
25 words
A double floor as in claim 1, characterized in that the floor plates are formed of a mineral material in a metal vat-shaped outer armature.
Claim 12
Dependent Claim
24 words
A double floor as in claim 1, characterized in that said upright bearings further comprise vertically adjustable holding plates for supporting said floor plates.
Claim 13
Dependent Claim
18 words
A double floor as in claim 1, characterized in that said pipes are formed of a deformable material.
