Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
164 words
Arrangement in floors of the kind which, under a load-carrying floor layer (1) of boards or panels, is provided with heating means in the form of pipes (2) adapted for having a heating medium in the vapour or liquid phase flowing through them, characterized in that a sub-floor (3) of heat-insulating slabs is formed with upwardly open channels (4) for the pipes; that along two opposing walls adjacent which the pipes are removably connected to distribution and collection heads (6), the sub-floor has recesses (5) running along these walls at an angle to the channels (4) for the distribution and oollec- tion heads, the load-carrying floor layer (1) in the area of the recesses (5) being formed with removable or openable boards or hatches (8); and in that the pipes (2) are of the soft kind, so that they are sufficiently flexible to be pulled out from, and thrust into the channels (4) via openings exposed by means of said boards or hatchets (8).
Claim 2
Dependent Claim
164 words
Arrangement in floors of the kind which, under a load-carrying floor layer (1) of boards or panels, is provided with heating means in the form of pipes (2) adapted for having a heating medium in the vapour or liquid phase flowing through them, characterized in that a sub-floor (3) of heat-insulating slabs is formed with upwardly open channels (4) for the pipes; that along two opposing walls adjacent which the pipes are removably connected to distribution and collection heads (6), the sub-floor has recesses (5) running along these walls at an angle to the channels (4) for the distribution and oollec- tion heads, the load-carrying floor layer (1) in the area of the recesses (5) being formed with removable or openable boards or hatches (8); and in that the pipes (2) are of the soft kind, so that they are sufficiently flexible to be pulled out from, and thrust into the channels (4) via openings exposed by means of said boards or hatchets (8).
Claim 3
Dependent Claim
78 words
Arrangement as claimed in claim 1, characterized in that the heat-insulating slabs (3) comprise cellular plastic slabs with let-in nailing battons (9) on their upper sides for attaching said floor layer (1), the channels (4) for the pipes (2) being substantially parallel to the nailing battons (9), and in that the recesses (5) for the distribution and collection heads (6) are substantially at right angles to the channels (4), and are consiged to separat cellular plastics slabs (10).
Claim 4
Dependent Claim
41 words
Arrangement as claimed in claim 1 or 2, characterized in that the heat-insulating slabs (3) have separate, outwardly open grooves (11) crossing the channels (4) for the pipes (2) in the portions of said slabs (3) passed through by the pipes.
Claim 5
Dependent Claim
35 words
Arrangement as claimed in claim 3, characterized in that the grooves (11) are filled with a material with better heat conductivity than the material in the heat-insulating slabs, e.g. a granular material and a binder.
Claim 6
Dependent Claim
62 words
Arrangement as claimed in any of claims 1 -4, characterized in that the channels (4) are clad with a foil (12) having good heat conductivity and preferably good radiation absorbing capacity also, following the bottom and side walls of the ohannel and preferably extending out over the upper side of the heat-insulating slabs (3) on either side of the respective channel (4).
Claim 7
Dependent Claim
46 words
Arrangement as claimed in any of claims 1 - 5, characterized in that the channels (4) are covered by foils (13) with good heat conductivity, whioh are laid out on the upper side of the heat-insulating slabs (3) said foils preferably having good radiation absorbing capacity.
Claim 8
Dependent Claim
115 words
Arrangement as claimed in any of claims 1 - 6, for the case where the load-carrying floor layer (1) comprises boards and is covered by a wall-to-wall carpet (18), characterized in that a strip (19) let into the boards runs under the carpet (18), over the respective joint between the boards made as an openable hatch (8) in the area of the recesses (5) for the distribution and collection heads (6) on the one hand, and the remaining boards in the load-carrying floor layer (1) on the other hand, this strip (19) being screwed into the heat-insulating slabs (3) by means of screws (21), the heads of which are preferably situated under the carpet (18).
