Definitions

  • the present invention relates to a method of producing a so-called "inverted roof” covering for a building, comprising a structural support, at least one layer of waterproof material disposed on the structural support, at least one layer of insulating material disposed on the material. waterproof and at least one protective charge placed on the insulating material.
  • the waterproofing layer was formed over the insulating layer, which exposed it to significant thermal shock and caused its relatively rapid degradation.
  • the layer for sealing against pressurized water and runoff inevitably has a higher resistance to the passage of steam than the other layers.
  • its temperature is below the dew point. For these two reasons the risks of condensation are certain.
  • classic waterproofing is undoubtedly the most vulnerable of the elements making up a traditional roof. Its lifespan is twenty years while that of other layers is at least sixty years. Aging is all the more rapid as the seal is outside, therefore subjected to ultraviolet radiation, thermal and mechanical shock and that it rests on a thermal insulating support, which subjects it to a thermal cycle.
  • inverted roofing which has been developed in particular thanks to the particular properties of certain synthetic materials, in particular extruded polystyrene foams, has made it possible to remedy most of the drawbacks of traditional flat roofs. Indeed to remedy the risks of condensation, the inverted roof makes it possible to place the waterproofing in an area where the temperature is above the dew point. This solution called “hot sealing” saves the costs of a vapor barrier.
  • the inverted roof also provides a solution to the fragility of the waterproofing layer, the service life of which can be considerably increased, since it is the waterproofing and not the thermal insulation which is protected against external agents. Finally, in inverted roofs, the waterproofing rests on an insulated support, where the movements are small, which eliminates the deterioration of the waterproofing caused by the expansion of the structural layers.
  • ballast of around 80 kg.m2 is made up of a gravel weighting layer whose thickness is at least equal to that of the insulation plates.
  • the present invention proposes to overcome all of the aforementioned drawbacks concerning both traditional roofs and inverted roofs.
  • the method according to the invention is characterized in that one forms the layer of insulating material deposited on the waterproof layer and the protective filler by means of prefabricated elements comprising a rigid slab made of a material composed of aggregates linked by a binder and a plate of a thermally insulating material, integral with the surface bottom of the rigid slab, in which the thermally insulating material is made of a non-hygroscopic synthetic material.
  • the prefabricated element for the implementation of this process is characterized in that the thermally insulating material is a non-hyroscopic synthetic material. Thanks to the prefabricated slabs made integral with the insulation plates, the drawbacks due to the bimetallic strip effect are eliminated.
  • the absence of gravel as a ballast layer considerably reduces the penetration of sand between the joints of the insulating plates and almost completely eliminates the risk of lifting of these plates by sands or gravels entrained by runoff water.
  • the extruded polystyrene foams which degrade under the effect of ultraviolet rays, are effectively protected by the compact ballast tiles effectively covering the entire surface of the insulating layer.
  • the traditional roof generally consists of a structural support 10 consisting of a concrete slab, on which are successively arranged a vapor barrier 11, a layer of insulating material 12, the sealing layer 13 and a filler protective 14. It can be seen that the sealing layer 13 is on the one hand in direct contact with the external ambient medium and with the insulated lower layers, which subjects it to significant thermal shocks which are at the origin of its degradation. relatively fast.
  • inverted roofs which are composed, as shown in fig. 2, a structural support 20 consisting of a concrete slab, on which are successively deposited the sealing layer 21, the insulating layer 22 and the protective filler 23 preferably consisting of gravel.
  • the waterproof layer 21 is well protected by the insulating layer 22 which is itself protected, in particular against ultraviolet radiation which degrades the extruded polystyrene, by a relatively large layer of gravel 23.
  • the opening of the seals 24 between neighboring plates can be large enough to allow the passage of sands or grains of gravel entrained by the runoff of rainwater, which ultimately become encrusted between the tight layer 21 and the insulating layer 22.
  • the relative movements of the plates constituting the insulating layer 22 are further amplified by the bimetallic strip effect due to the temperature difference appearing between the two faces of this insulating layer.
  • the inverted roof of fig. 3 again consists of a structural support 30 consisting of a concrete slab on which a waterproof layer 31 is deposited. This layer is then covered with prefabricated elements 32 each comprising a rigid slab 33 made of a material comprising bound aggregates by a hydraulic binder of the cement type, and a plate 34 of an insulating material bonded to the lower surface of the slab 34.
  • the plates 34 are preferably made of extruded polystyrene.
  • the plates 34 have the same shape and the same dimensions as the slabs 33. They are however offset laterally in one or two directions perpendicular to the slabs 33, to allow a partial superposition of the elements 32 placed adjacent.
  • Fig. 4 shows a particular embodiment, in which an inverted roof according to the invention has been put in place over an existing traditional roof.
  • This roof consists of a structural support 40, a vapor barrier 41, an insulating layer 42 and a waterproof layer 43.
  • a protective filler constituted by a layer of gravel which has been removed.
  • prefabricated elements 44 have been put in place as previously constituted by a concrete slab 45 and an extruded polystyrene plate 46.
  • the slabs 45 have, on at least one of their sides, a staircase-shaped rim 47 which corresponds to a complementary groove 48 which cooperates to allow the prefabricated elements to be superimposed during their installation.
  • the insulating plates 46 are offset with respect to the tiles 45, so as to constitute an additional baffle in the junction zone of two juxtaposed elements.
  • the existence of these baffles limits the penetration of sand or gravel entrained by the runoff of rainwater, and their deposition between the insulating layer 46 and the sealing layer 45.
  • Fig. 5 illustrates a particular embodiment of the prefabricated elements 50, constituted by a slab 51 of rectangular or square shape made of a material comprising aggregates linked by a hydraulic binder of cement type, and a plate 52 of the same shape and the same dimensions, preferably made of extruded polystyrene, and glued to the base of the slab 51 using an appropriate adhesive.
  • the plate 52 is offset in two directions perpendicular to the slab 50 to allow superimposition of the adjacent elements.
  • the lower surface of the slab 51 preferably comprises a series of longitudinal grooves 53 parallel to each other and oriented along the line of the greatest slope when the elements are in place on the roof of a building. These grooves 53 channel the rainwater, facilitate its rapid evacuation and thereby prevent the floating phenomenon which is likely to occur in the event of rainwater accumulating between the sealing layer and the insulation provided. Above.
  • the plate 52 could of course be replaced by several plates of insulating material superimposed and connected together by gluing.
  • the tiles can be made of an impermeable material or a permeable material.
  • the prior carbonation makes it possible to remove the calcareous concretions.
  • pozzolan cement or a mixture of cement.
  • Portland and Trass cement as a binder for aggregates used in the composition of this slab.
  • the load formed by this slab provides effective protection against the effects of ultraviolet rays, against the effects of floating and aspiration due to the infiltration of rainwater between the joints.
  • the grooves 53 intended to channel the runoff water which has entered between the joints may have any shape designed so as to favor the flow of the variable quantity of rainwater which would have entered between the joints of the juxtaposed elements. This structuring could be determined case by case depending on the slopes of the roof. It should be planned in such a way that the water path is as short as possible, that is to say that the grooves follow approximately or form an acute angle with the line of greatest slope of the roof.
  • the insulating plates 52 are preferably fixed to the slabs 51 by a thin intermediate layer 54 ensuring good adhesion between the two extreme elements.
  • This layer may consist of a solvent-free layer capable of attacking and dissolving the insulating material, or an adhesive mortar of the Polyton® 2470 type, which will preferably have a breaking strength of at least 2 kg / cm 2 . This mortar will also have the property of validly diffusing water vapor.
  • the manufacture of the prefabricated elements 50 can be done in two ways.
  • the slabs 51 are subjected to an accelerated carbonation treatment, the actual slab is first molded and dried, the plate of insulating material being fixed thereafter.
  • the plate 52 can be fixed directly to the outlet of the slab manufacturing machine. In both cases, the slab 51 is placed in such a way that its lower surface faces upwards, the insulating plate 52 is placed appropriately and the assembly is turned over so that the weight of the slab 51 ensures the pressure necessary to obtain good adhesion of the two elements 51 and 52.
  • FIG. 6 illustrates another form of the element in FIG. 5.
  • the slab 61 comprises a first series of grooves 62 of square or rectangular profile and a second series of grooves 63 identical or 4 not, arranged perpendicular to the grooves 62.
  • the slab 61 is as previously fixed to the plate 64 using a layer of glue or adhesive mortar 65.
  • Figures 7, 8, 9 and 10 illustrate by way of example four tiles 71, 81, 91 and 101 respectively, the contact surface of which with a plate (not shown) identical to the plates 52 and 64 of the elements shown in Figures 5 and 6, are profiled so as to facilitate the flow of runoff water. Thanks to the symmetry of these profiles, the runoff water does not encounter any obstacle to flow in the direction of the greatest slope of the roof, whatever the direction in which the elements produced using these slabs are placed. .
  • FIG. 11 represents a perspective view of another embodiment of a slab 111.
  • the lower surface of the slab has a symmetrical profile which promotes the flow of runoff water whatever the directions of pose of the element.
  • FIG. 12 illustrates an embodiment according to which the tiles 121 have an octagonal shape, and the tiles 122 intended to close the areas not covered by the tiles 121 have a diamond or square shape.
  • the insulating plates 123 can be square in shape and are offset laterally with respect to the tiles. In this way, the slots between slabs and plates are not superimposed and the risks of sand being inserted under the plates are greatly reduced.
  • the slabs do not have a metallic reinforcement.
  • the insulating plates have sufficient crush resistance to support the weight of a vehicle.
