Abstract

Abstract A construction member made of a material of good thermal conductivity has the shape of a board. Along one longitudinal edge a rib projects from the lower surface of the board at substantially right angles which rib serves to support the board on the ground. In the junction area between the board and the rib a channel is provided extending in longitudinal direction for receiving a heating pipe. On the upper surface of the construction member along the edge above the rib a recess is formed for receiving the rib-free edge of the adjacent member. By assembling a plurality of construction members side by side a floor above the ground is formed at a distance equal to the width of the supporting ribs, and the ribs subdivide the space between the floor and the ground into channels wherein the air is warmed up. Holes are provided in the board-shaped portion of the construction member through which the warm air escapes into the space above the floor.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 177 words
A construction member for assembling a heated floor at a certain distance above a base, said member comprising: a. a board-shaped elongated portion defining a thermally conductive upper surface and lower surface (1), and b. a supporting rib (3a) projecting substantially at right angles from said lower surface and extending along one longitudinal edge thereof, said rib supporting said elongated portion on said base, both said elongated portion and said supporting rib being one integral piece and made of a material of good thermal conductivity, and a hole being provided therein, extending in longitudinal direction in the junction area of said elongated portion and said supporting rib for receiving a heat-conducting medium, c. connecting means (7;27;29) extending along the longitudinal narrow sides of said elongated portion, said means being adapted to connect each construction member to the adjacent construction members when a floor is assembled therefrom, and d. a plurality of holes (5) in said board-shaped elongated portion for permitting warm air to rise from underneath said portion through said holes into a room above said portion.
Claim 2
Dependent Claim 177 words
A construction member for assembling a heated floor at a certain distance above a base, said member comprising: a. a board-shaped elongated portion defining a thermally conductive upper surface and lower surface (1), and b. a supporting rib (3a) projecting substantially at right angles from said lower surface and extending along one longitudinal edge thereof, said rib supporting said elongated portion on said base, both said elongated portion and said supporting rib being one integral piece and made of a material of good thermal conductivity, and a hole being provided therein, extending in longitudinal direction in the junction area of said elongated portion and said supporting rib for receiving a heat-conducting medium, c. connecting means (7;27;29) extending along the longitudinal narrow sides of said elongated portion, said means being adapted to connect each construction member to the adjacent construction members when a floor is assembled therefrom, and d. a plurality of holes (5) in said board-shaped elongated portion for permitting warm air to rise from underneath said portion through said holes into a room above said portion.
Claim 3
Dependent Claim 36 words
A construction member as claimed in claim 1, and further comprising additional ribs (2) extending in longitudinal direction in parallel to said supporting rib, said additional ribs being of a smaller width than said supporting rib.
Claim 4
Dependent Claim 22 words
A construction member as claimed in claim 2, and further comprising transverse ribs (4) of a smaller width than said supporting rib.
Claim 5
Dependent Claim 51 words
A construction member as claimed in claim 1, wherein said connecting means comprise a tongue (29) projecting from one narrow side of said elongated portion and a groove (27) cut into the opposite narrow side of said elongated portion and being adapted to receive the tongue of the adjacent construction member.
Claim 6
Dependent Claim 49 words
A construction member as claimed in claim 1, wherein said connecting means comprise an L-shaped recess (7) cut into the upper surface of said elongated portion along the upper longitudinal edge above said supporting rib, said recess being adapted to receive the rib-free edge of the adjacent construction member.
Claim 7
Dependent Claim 18 words
A construction member as claimed in claim 1, wherein said upper surface of said elongated portion is cast-raw.
Claim 8
Dependent Claim 35 words
A heated floor assembled from the construction members claimed in claim 1, wherein the supporting ribs define channels (11) underneath the floor to which air supply channels (18) are connected adjacent the room walls (17).
Claim 9
Dependent Claim 17 words
A heated floor as claimed in claim 7, and further comprising fans in the air supply channels.
Claim 10
Dependent Claim 19 words
A heated floor as claimed in claim 7, and further comprising an air-permeable carpet (9) spread on the floor.
Claim 11
Dependent Claim 28 words
A heated floor as claimed in claim 9, wherein the carpet is attached to the floor by adhesive means distributed puntually between the holes in the construction members.
Claim 12
Dependent Claim 17 words
A heated floor as claimed in claim 7, wherein said base has a heat reflecting layer thereon.
