    • E04D11/02—Build-up roofs, i.e. consisting of two or more layers bonded together in situ, at least one of the layers being of watertight composition

Definitions

  • the invention relates to a drivable cover layer for a flat roof or the like, comprising an insulating layer and/or a water-tight layer and a drivable top layer positioned there above, said top layer comprising a sheet-like upper layer and a lower layer which is supported by the insulating layer and/or the water-tight layer.
  • a cover layer of this type is known from US-A-4.530.193 and is used for insulating and protecting relatively flat roofs.
  • the insulating layer comprises insulation panels made, for example, of expanded foamed polystyrene whereas the water-tight layer comprises a water impermeable membrane.
  • the lower layer and the upper layer of the top layer consist of extruded, foamed polystyrene panel members and a cementatious coating, respectively. These polystyrene panel members are bonded to the coating.
  • This known cover layer however is not meant to be driven on.
  • Another known cover layer is used in a parking roof.
  • the top layer of this cover layer has to withstand the loads of vehicles on top of said parking roof without the insulating layer and/or the water-tight layer being damaged.
  • the top layer of this known cover layer comprises for example a lower layer of concrete plates positioned on supports and extending at some distance above the insulating layer and/or water-tight layer, and an upper layer of melted asphalt positioned on said concrete plates. Loads occurring are led into the roof construction through the supports and thus do not lead to unacceptable stresses in the insulating layer and/ or water-tight layer.
  • a disadvantage of this known cover layer is the high weight, amounting about 150 to 200 kg/m 2 .
  • the average load induced by vehicles on top of the cover layer amounts about 50 to 150 kg/m 2 .
  • the high cover layer weight sets high demands to the roof construction and often obstructs the application of this cover layer when adapting existing roofs to parking roofs.
  • the cover layer according to the invention is characterized in that the upper layer comprises a metal sheet, such as an aluminum sheet, whereas the lower layer is elastic and comprises a rubber material adhered to the upper layer by vulcanisation or glueing along the entire surface thereof and wherein the top layer is connected to the insulating layer and/or water-tight layer by means of an adhesive.
  • the upper layer comprises a metal sheet, such as an aluminum sheet
  • the lower layer is elastic and comprises a rubber material adhered to the upper layer by vulcanisation or glueing along the entire surface thereof and wherein the top layer is connected to the insulating layer and/or water-tight layer by means of an adhesive.
  • the sheet-like upper layer is extremely suitable for carrying concentrated loads, for example the wheel pressure of vehicles.
  • these concentrated loads are regularly divided over the entire surface of the insulating and/or water-tight layer that as a result nowhere experiences an unacceptable high pressure.
  • the load dividing action of the elastic lower layer is influenced positively through the fact that this lower layer is connected to said upper layer along its entire surface.
  • top layer is connected to the insulating layer and/or water-tight layer by means of an adhesive, there is provided a further improvement of the behaviour of the elastic lower layer.
  • the drawing illustrates a flat roof construction 1 known per se, that either is specially constructed to be provided with a drivable top layer or will be adapted for this reason.
  • the flat roof construction 1 can be constructed more lightweighted than when using a conventional top layer, whereas in the second case the already more lightweighted construction will be of no problem when applying the drivable top layer.
  • an insulating layer 2 On the roof construction 1 are provided an insulating layer 2 and a water-tight layer 3 of a known type. It is possible to interchange these two layers 2, so that the insulating layer 2 will be on top of the water-tight layer 3.
  • the top layer comprises a sheet-like upper layer 4 and an elastic lower layer 5.
  • the upper layer 4, that comprises a metal sheet, is connected to said upper layer 5 along its entire surface.
  • the lower layer 5 comprises a rubber material, such as a granular rubber bound with polyurethan
  • the connection between the lower layer 5 and the upper layer 4 will be obtained by vulcanisation.
  • an adhesive layer 6 is provided between the lower layer 5 and the water-tight layer 3 .
  • Said adhesive layer 6 comprises for example a cold adhesive.
  • the metal sheet 4 is provided with a profile 7 and defines a so-called tears-sheet.
  • the profile 7, that can have every suitable shape, enlarges the roughness or the coefficient of friction of the outer surface of the metal sheet 4, offering a suitable drivable surface.
