Definitions

  • the invention relates to a composite sheet comprising a lower insulating supporting layer, particularly made of foam plastic material, and a top layer disposed thereon and joined thereto, particularly made of rubber and/or concrete.
  • Such a composite sheet comprising a lower insulating bearing layer and a top layer made of rubber and/or concrete disposed thereon, is known.
  • the object of the invention is now to provide a composite sheet of the above-mentioned type which does not or substantially does not present these disadvantages.
  • the supporting layer has on at least one upright face a part projecting beyond the periphery of the top layer and on an opposite upright face has a recess extending within the periphery of the top layer and matching the projecting part.
  • a lower layer part of the supporting layer is staggered relative to the face determined by the periphery of the top layer. This gives the great advantage that the projecting part of a composite sheet which is used for a roof covering extends completely over the surface of the roof on which the composite sheet has been places. In this way, optimum insulation of the roof is obtained with the use of a composite sheet of the type mentioned above.
  • the composite sheet comprises particularly preformed rigid foam plastic layer on which the top layer is disposed. If the top layer is made of concrete, a foam plastic supporting layer is placed in a mould and a mixture of a setting binder and fillers, such as granules, is then placed on the plastic layer, following which the desired top layer .suitable for walking on is obtained once the binder has set.
  • the binder can be a hydraulic binder such as cement, but can also be a thermosetting synthetic resin binder.
  • the top layer for walking upon of rubber more particularly granulated rubber which has a low coefficient of expansion and exhibits very good sound absorption when it is walked upon.
  • it provides a composite sheet of the above mentioned type, in which optimum joining of the lower insulating supporting layer and the top layer for walking upon disposed thereon is obtained, and even when there is damage to the insulating supporting layer at the transition to the top layer, a very good join between top layer and insulating supporting layer is ensured.
  • a composite sheet comprising a lower insulating supporting layer, particularly made of foam plastic material, and a top layer for walking upon disposed thereon and joined thereto, particularly made of rubber and/or concrete, is therefore characterized in that the top layer is provided with edge parts extending under the top face of the insulating supporting layer and being anchored in matching edge recesses of the supporting layer.
  • such a composite sheet provided the great advantage that differences in expansion which occur between the insulating supporting layer and the top layer which can be affected by direct sunlight do not lead to cracks in the top layer or in the insulating supporting layer.
  • Providing the top layer with edge parts which are anchored in matching edge recesses of the insulating supporting layer being located under the top face of the insulating supporting layer means that a good attachment is ensured, while the edge parts also ensure that good cohesion of the insulating supporting layer is retained.
  • edge parts it is particularly advantageous for the edge parts to extend along the entire periphery of the top layer, which ensures optimum protection of the join between top layer and insulating supporting layer and also holds the insulating supporting layer clamped between the continuous edge parts.
  • the matching edge recess in the insulating supporting layer is very advantageously designed as an undercut groove which ensures very good anchoring between top layer and insulating supporting layer and, on the other hand the production of such a composite sheet is simple, since the mortar used for forming a top layer can penetrate well into said undercut groove.
  • top face of the supporting layer and the opposite bottom side of the top layer are free from any adhesive binding these surfaces, so that when there are differences in expansion the top face of the insulating sheet and the opposite bottom side of the top layer can move freely relative to each other.
  • Fig.1 shows a tile, for example with the dimensions 30 by 30 cm, comprising a top layer 2 and disposed thereunder an insulating supporting layer 3.
  • the top layer is made of concrete and is applied by placing the insulating supporting layer 3 in a mould and then placing a fluid mortar made of a hydraulic binder 19 and gravel particles 17 on top of the insulating supporting layer 3.
  • the insulating supporting layer 3 comprises a top layer part 3b which is directly joined to the top layer 2.
  • the upright wall parts 27 of this layer part 3b form the extension of the upright faces 9, 10, 11 and 12 of the top layer.
  • the insulating supporting layer 3 of rigid expanded plastic material has a lower layer part 3a which is staggered relative to the top layer 2.
  • the bottom side of the composite sheet therefore exhibits projecting parts 4 and 4' and on the opposite side matching recesses 5, 5'.
  • the lower layer part 3a of the supporting layer 2 is bounded by two successive upright walls 6, 7 which extend outwards and at a distance from the extension of the wall faces 10, 11 of the top layer which are situated above, thereby forming projecting parts 4, 4', and the opposite upright walls 8, 9 of the lower layer part extend inwards and at a distance from the extension of the wall faces 12, 13 of the top layer which are situated above, thereby forming recesses 5, 5' which match the projecting parts 4, 4'
  • Fig.3 that at the transition between two successive tiles there is a slit 20 which in the absence of projecting parts 4, 4' would extend from the outside to the roof surface on which such composite sheets in the form of tiles are placed.
  • This "cold bridge effect" which adversely affects the insulation of the roof, is eliminated by the top face 21 of a projecting part 4 of a first tile being covered by the bottom face 22 of the recess 5 of another tile.
  • the top layer 2 is provided with edge parts 16 which extend along the entire periphery of the top layer and which are anchored in edge recesses 15 of the insulating supporting layer which are designed as undercut grooves.
  • the undercut groove or edge recess 15 comprises a groove bottom part 15a and a slanting groove part 15b which intersect each other in edge 15'. If at the point of transition form the insulating supporting layer 3 in the form of a foam plastic sheet to groove bottom part 15a damage occurs to the foam plastic sheet 3, this does not lead to the ultimate breaking of the join between top layer 2 and insulating foam plastic sheet 3, since the actual join is ensured by the edge parts 16 and matching recesses 15 in the form of an undercut groove.
  • the edge parts 16 and recesses 15 also ensure good retention of cohesion of the foam plastic sheet 3.
  • the edge parts 16 extend under the top face 14 of the insulating sheet 3.
  • Figs. 4 and 5 show a tile according to a different aspect of the invention, in which case an optimum join between top layer and insulating supporting layer is ensured, said composite sheet is particularly suitable when using a top layer 2 of concrete and a foam plastic sheet as insulating supporting layer 3.
  • top layer and insulating supporting layer 3 The join between top layer and insulating supporting layer 3 is achieved as described above.
  • top layer 2 and insulating supporting layer 3 it may be advisable to form in the foam plastic sheet 3 at least one swallow- tailed longitudinal groove 24, bounded by longitudinal groove bottom part 24b and from this bottom part 24b converging to upward-running walls 24a which end in the edges 24', 24" on the top face 14 of the insulating foam plastic sheet.
  • the insulating foam plastic sheet 3 can be provided with at least one other longitudinal groove 25 which extends perpendicular to the first longitudinal groove 24.
  • This longitudinal groove 25 will end on the top face of the insulating foam plastic sheet 3 in the edges 25' and 25".
  • the longitudinal groove 25 is bounded by longitudinal groove bottom 25a and longitudinal groove walls 25b converging upwards.
  • the top layer 2 as used is preferably a vapour-permeable layer.
  • the layer can consist of concrete, but can also be made from fillers and a thermosetting resin, and it must, of course, be ensured that the material of the insulating sheet is not attacked by the synthetic resin.
  • the top layer can also be formed from rubber granules.
  • the surface bounded by the middle of a longitudinal groove 24 and 25 and the opposite outside of the top layer 2 is expediently smaller than 625 cm 2 and pre-2 ferably smaller than 400 cm .
  • the longitudinal grooves 24 and 25 running perpendicularly to each other are therefore provided in the centre as shown in Fig.4, and this means that there can certainly be no damage due to expansion.
  • top face 14 of supporting layer 3 and bottom side 18 of top layer 2 can move freely relative to each other, so that expansion does not lead to cracks in one of the two layers.
