Definitions

  • the invention relates to an air underfloor heating system in which at least one cavity is provided for the passage of heated air between an insulation layer lying at the bottom and a heat-conducting base layer supporting the floor covering.
  • These air lines consist of sheet metal tubes with a rectangular cross-section.
  • These sheet metal pipes are connected on the one hand to air distributors, which are usually provided in the middle of the building, and on the other hand, the sheet metal pipes open into outlet bends that are embedded in the floor and are covered at the top by a grille. These exit arches are usually located near the outer walls.
  • the heat transfer takes place on the one hand from the sheet metal pipes directly to the base layer and from there via the floor covering to the room, and on the other hand the air flowing into the room from the outlet arches emits its heat.
  • this known air underfloor heating is relatively expensive to manufacture and laborious to assemble.
  • the sheet metal tubes themselves are composed of individual pieces.
  • this known underfloor underfloor heating also has the disadvantage that heat is only given off to the floor at individual points in the immediate area of the sheet metal pipes.
  • a warm water underfloor heating system is also known, in which individual shaped plates are laid next to one another. These form plates are provided with channels on the top into which the heating pipes are laid. Prefabricated, large-scale building panels are then placed on the form plates and a floor covering is glued to them.
  • the invention has for its object to provide an air underfloor heating of the type mentioned, which is simple in construction and assembly and in which the floor is heated uniformly over the entire surface.
  • the new air underfloor heating is characterized above all by its extremely simple construction and simple assembly.
  • the invention is based on the idea of creating a coherent cavity between the insulation layer and the base layer.
  • This cohesive cavity has the advantage that the heated air can be supplied to the cavity at any point and that air outlet openings can be provided at any point by making recesses in the building boards serving as a support layer at the desired points.
  • Such recesses can, if necessary, also be provided retrospectively after the building boards have been laid. Due to the contiguous cavity, the entire floor area is heated evenly at all points. This also ensures better heat transfer.
  • the installation of the new air underfloor heating is also significantly simplified by dispensing with any pipes between the insulation layer and the base layer. The cumbersome connection of these pipes is no longer necessary. The interconnected spacers are simply placed on the insulation layer and the building boards can be laid on them immediately.
  • wire mats which consist of several bent and interconnected wires, are particularly suitable as coherent spacers. It is only important that such wire mats have the necessary compressive strength and allow air to pass in any horizontal direction.
  • wire mats plastic or metal plates can also be used, on which the spacers are formed by deep drawing.
  • the new air underfloor heating has the further advantage that the overall height of the floor construction is kept smaller can than when using piping.
  • the entire cavity formed between the insulation layer and the building boards is used for the passage of air. Since this cavity extends over the entire width or length of a room, it can have a relatively small height and there is then still a sufficient cross section for the passage of air.
  • 1 denotes the ceiling of a building and 2 its outer wall.
  • An insulation layer 3 is arranged on the ceiling 1.
  • a channel 4 is provided for supplying heated air and can be arranged at any point.
  • a multiplicity of interconnected, spaced apart and permeable air passages in each horizontal direction are provided on the insulation layer 3
  • Spacers 7 are provided.
  • Prefabricated building boards 8 are arranged on the spacers 7 as a base layer. These building boards can be provided at any points with air outlet openings 9, in which grids 10 are inserted in a known manner.
  • the floor covering 11 is glued to the building boards 8.
  • wire mats that consist of several bent and interconnected wires are suitable as interconnected spacers. Such wire mats are also referred to as wire mesh. It is only important that the wire mats have a sufficient height h or h1 and allow air to pass through in any horizontal direction.
  • the wire mat consists of a plurality of wires 7 which are arranged in parallel and at a distance a from one another and are alternately bent in a U shape in the opposite direction. These wires 7 are connected to one another by welded-on transverse wires 12.
  • the wire mat consisting of wires 7 and 12 is a commercially available component.
  • FIGS. 5 and 6 show a wire mat 13, the helically curved wires 13a and 13b of which are interconnected and serve as spacers in the sense of the invention.
  • the wire mat 13 consists of a plurality of wires 13a bent helically in a first direction A. Each two adjacent wires 13a interlock with their screw turns.
  • In the wire mat 13 there are also a plurality of wires 13b, likewise bent helically, the screw axes of which extend perpendicular to the first direction A in direction B.
  • These wires 13b also engage with one another with their screw turns and at the same time they also engage in the screw turns of the wires 13a.
  • plastic ones can also be used.
  • a plurality of cup-like depressions 14a arranged at a distance a1 from one another are provided in a plastic or metal plate 14 which consists of thermoplastic plastic.
  • These cup-like depressions 14a can be produced in a known manner by deep-drawing the plastic plate using heat and vacuum.
  • stiffening ribs 14b are provided between the individual cup-like depressions 14a, which are also produced by deep drawing.
  • the cup-shaped depressions 14a are open towards the underside 14c of the plastic plate and an insulation plate 15 is glued to the underside 14c.
