Definitions

  • the invention relates to a floor element that has a walk-in chipboard on its top and a plate made of foamed plastic on its underside as an insulation and ventilation layer, the top and bottom from side wall to side wall continuous and similar and parallel grooves between them Has support surfaces forming webs.
  • Such floor elements have the purpose of isolating the room above from the cold rising from the rooms below and to serve as sound insulation between the rooms below and above.
  • the moisture rising from the concrete screed should be dried out via the groove system of the foam plate before it can penetrate the wood fibers of the step plate.
  • DE PS 25 08 628 describes a floor element which has grooves on the top of its foam sheet, which are offset from parallel grooves of the same type on the underside of this foam sheet.
  • the moisture penetrating from the concrete screed over the contact surface of the webs remaining between the grooves on the underside is said to be diffused and pumped by treading in the air contained in the grooves according to the sidewalls of the foam sheet and flush grooves of the similar foot elements laid in the dressing after gaps between the grooves floor covering composed of these floor elements and the room walls are dissipated to the atmosphere. If there is a large amount of liquid, however, the surface of the groove walls thus offered is not sufficient for drying out and a moisture transfer into the chipboard and its warping can then no longer be avoided.
  • DE OS 34 43 705 describes a floor element in which the grooves are cut at right angles to one another, so that only blocks with a square contact surface remain between them instead of strips. As a result, the areas giving off the moisture become larger.
  • this arrangement has the disadvantage that when cutting this plate, in contrast to the one described in the aforementioned PS, there is a considerable amount of waste and the top and bottom sides have to be cut twice each.
  • a further disadvantage is that the moisture loading of the lower layer of the foam sheet will always be greater than that of the upper one, since the moisture content of the air in the lower groove system is always greater than that in the upper groove system. Since there is no connection between these two systems, their moisture content cannot be compensated. This leads to an uneven increase in volume of the foam, that is, to an expansion of the lower layer of the foam sheet compared to the upper. A warping of the floor element cannot therefore be avoided with the arrangements described, this effect occurring all the more, the thicker the foam sheet or the more compact the foam forming it. Low density foams, in which this effect could possibly be neglected, do not meet the requirements of such floor elements.
  • the invention is therefore based on the following objects:
  • the moisture-giving walls of the groove system are to be enlarged without any waste material being produced when the foam sheet is cut in series production.
  • the contact surfaces of the foam sheet should be kept as small as possible in order to reduce the possibility of moisture transfer.
  • a warping of the foam sheet due to the uneven moisture content of its top and bottom layers is to be prevented.
  • Air circulation is to be made possible, which covers the entire groove system together.
  • the floor element shown in Figure 1 has a chipboard 1 and on the underside of an insulating part made of foamed plastic, which is divided into a horizontal plane. Its lower part is formed as a ventilation layer 3 by cutting the grooves 4 into their underside and grooves 5 crossing them on their upper side.
  • the upper part, the actual insulating layer 2 with plane-parallel bearing surfaces, can be of different thicknesses depending on the requirements placed on thermal or acoustic insulation.
  • the underside of the ventilation layer 3 the floor element lies directly on the concrete screed, not shown.
  • the grooves 4 and 5 have the same trapezoidal cross section and allow the lower webs 6 and the upper webs 7 to stand between them.
  • These webs 6 and 7 have a cross section which is congruent with the grooves 4 and 5, but in each case in the opposite position.
  • the grooves 4 and 5 have a greater depth than half the thickness of the ventilation layer 3, so that they penetrate each other in a narrow area at a height of about 2 mm downwards and upwards relative to the horizontal central plane 8 of the ventilation layer. This results in windows between the crossings of the lower webs 6 and the upper webs 7.
  • These windows 9 have a square cross section at the bottom of the grooves 4 and 5 and they intersect the mutually inclined side walls 10 and 11 of the lower grooves 4 and the obliquely ascending side walls 12 and 13 of the upper grooves 5 each trapezoidal at a height of 2 to 4 mm.
  • recesses 16 are provided in alignment with one another in the direction of the support surfaces 15 of the upper webs 7 and in a vertical projection of these upper support surfaces.
  • recesses 17 are provided in the support surfaces 15 of the upper webs 7, which are aligned in the direction of the support surfaces 14 of the lower webs 6 and in their vertical projection.
  • the formation of the window 9 creates a connection between the lower and upper grooves 4 and 5, which creates an air circulation between them and thus a compensation of the moisture content of the air between all the lower grooves 4 and all the upper grooves 5 with each other and the passages that the recesses Form 16 and 17 allows. It is therefore possible to distribute greater moisture accumulated in individual areas uniformly to all groove spaces and to dissipate it by diffusion over all wall-side ends of the grooves 4 and 5, that is to say over a large cross-sectional area.
  • the recesses 16 and 17 interrupt the contact surfaces 14 and 15 of the webs 6 and 7. In particular in the lower webs, this reduces the contact surfaces between the contact surfaces 14 of the webs 6 and the moisture-emitting concrete screed. Likewise, the contact surface 15 of the upper webs 7 to the overlying insulating layer 2 or the chipboard 1, if the insulating layer 2 is dispensed with, and thus a direct rise in moisture in connection with the drying effect almost impossible.
  • the shape and configuration of the ventilation layer 3 described here has the advantage that it can be cut out in series from a block of foamed plastic with the cross section of the vertical top view surface of the floor element and with any length without being cut.
  • the cutting tool for example a heated wire 18 in the case of polystyrene foam, is bent in a trapezoidal curve following the course of the vertical section through the surface of the grooves 4 and the webs 6.
  • the block 19 is first cut several times from one side parallel to its cross-sectional area in the distance between the bottom of the grooves 4 and the contact surfaces 15.
  • the block 19 is then rotated through 90 ° and cut again several times with the same cutting tool at the same distance between the individual cuts as in the first series of cuts, the distance between the cuts of the first series of cuts and those of the second series of cuts due to the desired depth of the windows 9 is determined.
  • the windows 9 are formed on the one hand by the protrusions of the webs 6 and 7 above the central plane 8 the recesses 16 and 17 on the other hand.
  • the block 19 disintegrates without any waste with the exception of the cut into the individual ventilation layers 3, which can then be glued to the insulating layer 2 according to the desired thickness and the wood chipboard 1.
  • the trapezoidal cross sections of the grooves have the further advantage that they are favorable for noise reduction, which applies to the grid-shaped arrangement of the webs 6 and 7 anyway.
  • the insulating layer 2 can be arranged on the underside of the ventilation layer 3 and the chipboard 1 on the top thereof.
  • the insulating layer 2 can have different thicknesses, for example thicknesses of 2, 4, 6 or 8 cm.
  • a design of the insulating layer is proposed below, according to which this can be placed in different thicknesses on the underside of the ventilation layer and clamped by toothing.
  • FIG. 6 Such an insulating layer is shown in FIG. 6. Its top 20 has parallel grooves 21 of the same geometry as that of the grooves 4, 5 of the underside of the ventilation layer, with the restriction that they do not reach the depth of these grooves 4, 5 of the ventilation layer 3. The height of the webs 22 remaining between the grooves 21 of these Insulating layer 23 should not be higher than the distance between the central plane 8 of the ventilation layer 3 and its lower contact surface 14.
  • This insulating layer 23 designed in this way can be inserted or pressed with its webs 22 into the grooves 4 in the underside of the ventilation layer 3 and adheres there due to the roughness of the surfaces pressed against one another by a wedge effect, so that the floor element can be transported and laid with an insulating layer, like a glue.
  • the cavity 24 resulting from the low height of the webs 22 is retained as a ventilation duct.
  • transverse ventilation channels resulting from the recesses 16 of the webs 6 of the underside of the ventilation layer 3 are cut off by the webs 22 of the insulating layer 23 and to create larger cavities for the ventilation channels in the grooves 5 of the insulating layer 2
  • transverse grooves 25 which can have the same geometry as the grooves 21, but in any case the same depth as this, so that the groove bottom of the grooves 21 and the transverse grooves 25 lie in the same plane. This is shown in top view in FIG.
  • the insulation layer 23 can be produced in an analogous manner to that shown in FIG. 4 by rotating the blank block through 90 °, but with the same setting of the cutting device.
  • the insulating layers designed in this way 23 in different thicknesses, for example 2, 4, 6 or 8 cm, and cut grooves 26 on their underside with the same geometry as the grooves 21 on the top.
  • a further insulating layer of the same type can then be inserted into this underside designed in this way, and another one and so on, as shown in FIG. 6, these insulating layers having different thicknesses, so that floor elements of the desired height are obtained.
  • the transverse grooves 25 are only required in the case of the insulating layer which lies directly against the ventilation layer.
