Definitions

  • the invention relates to a composite sheet comprising a lower insulating supporting layer of foam plastic material, and a top layer for walking upon disposed thereon and joined thereto made of rubber and/or concrete, said supporting layer having on at least one upright face a part projecting beyond the periphery of the top layer and on an opposite upright face having a recess extending within the periphery of the top layer and matching the projecting part, said supporting foam plastic layer comprising free upstanding sides capable of engaging a supporting foam plastic layer of another composite sheet over a substantial height of the supporting layer.
  • Such a composite sheet in the form of a tile is known from EP-A-0 088 198.
  • This sheet comprises a lower insulating support layer of polystyrene foam and a top layer made of concrete disposed thereon and adhered thereto by means of an adhesive.
  • This known composite sheet which is used for forming a roof covering suitable for walking on presents the disadvantage that due to the different expansion properties of the supporting layer of foam plastic material and of the top layer and the fact that the foam plastic material is integral with the top layer, the foam plastic material is rather rapidly damaged due to the formation of cracks in the foam plastic.
  • the object of the invention is now to provide a composite sheet of the abovementioned type which does not or substantially does not present this disadvantage.
  • the top layer is provided with edge parts extending under the top face of insulating supporting layer and being anchored in matching edge recesses of the supporting layer and the top face and the supporting layer of the opposite underside of the top layer are free from an adhesive binding these surfaces.
  • such a composite sheet provides the great advantage that differences in expansion which occur between the insulating supporting layer and the top layer which can be effected by direct sunlight do not lead to cracks in the insulating supporting layer.
  • DE-A-24 05 949 discloses a steel reinforced concrete element having a top layer provided with edge parts extending under the top face of an insulating foam plastic layer, said edge parts being anchored in matching edge recesses of the insulating foam plastic layer.
  • the free upstanding sides of the insulating foam plastic layer are substantially over their complete height enclosed by downwardly extending concrete walls, except a bottom layer of a very small thickness extending outside the downwardly extending walls at two subsequent sides and on the other hand ending before the downwardly extending walls at the two other sides.
  • the foam plastic layer is in in this case not a supporting layer as the concrete element is supported by concrete parts of the building.
  • FR-A-2.538.430 discloses an element of polystyrene connected with a top layer of plaster, the top layer being provided with edge parts extending under the top face of an insulating foam plastic layer, said edge parts being anchored in matching edge recesses of the foam plastic layer.
  • these elements are not suitable as walking on elements in outside roof coverings.
  • a lower layer part of the supporting layer is staggered relative to the face determined by the periphery of the top layer.
  • 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 composite sheet of the invention in particularly suitable to suppress the phenomenon of concrete resonance when walking over a roof of composite sheets of the invention.
  • 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.
  • the invention also relates to a roof covering formed from composite sheets according to the invention.
  • FIG. 1 shows a composite sheet according to the invention in the form of a tile
  • 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 3 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'
  • 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 from 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.
  • 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, bounded by longitudinal groove bottom part and from this bottom part converging to upward-running walls which end in edges on the top face 23 of the insulating foam plastic sheet.
  • the insulating foam plastic sheet 3 can be provided with at least one other longitudinal groove which extends perpendicular to the first longitudinal groove This longitudinal groove will end on the top face of the insulating foam plastic sheet in the edges.
  • the longitudinal groove is bounded by longitudinal groove bottom and longitudinal groove walls 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 and the opposite outside of the top layer 2 is expediently smaller than 625 cm2 and preferably smaller than 400 cm2.
  • the longitudinal grooves running perpendicularly to each other are therefore provided in the centre 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.
