Definitions

  • This present invention refers to a pavement slab the obvious aim of which it to be constituted as insulation and drainage element.
  • This invention has its application within the industry devoted to construction, being specially fit to be used as an element aside from paving, constituted as insulation and drainage.
  • This problems may cause, as well, losses in its staunch performance since the mortar adhered to the waterproof membrane becomes cracked and it carries along with it, and at the same time breaks due to the fact of soliciting enlargement, in only one point or line, which is impossible due to the waterproofing film which may support it.
  • the slab considered as idoneous, as well, must be capable of performing when it is placed on fully plain covers in which drainage is performed by gravity and level increase, with the water remaining inside the slabs, these having been perfectly designed in order that in the event water should freeze in their inside this may be freely expand inside the slab through its macropores thus not giving rise, in view of the special constitution thereof to crackings.
  • the slab pretended to be idoneous should constitute by itself an insulating and draining pavement with a weight lower than the traditional one which, as a consequence thereof, implies a significant reduction in its dead weight which the forgings and structures should bear.
  • the paving slab which the invention proposes is fitted with the draining property in all senses, thus allowing to build benches, walls or ramparts directly upon it, with which the designer may place the sumps wherever he may deem fit, not bearing in mind the situation of the new constructions.
  • the paving slab is constituted with the specification of being insulating and draining, being place on site with no anchoring material whatsoever, directly setting it upon the waterproofing itself on which stands its insulating coat, soft and cushioning by nature, with which it is obtained that not only the waterproofing or impermebealizing coating is not spoiled but at, the same time, that it may have an additional protection.
  • the paving slab being claimed is constituted as a filtering pavement, constituting a piece provided with three coatings.
  • the first coating is a concrete or cement mortar with the adition of resins and pigments, which allows, besides obtaining a large variety of patterns by merely modifying the mould surface, making it in various colours and to increase its mechanical stress and confer stability against ultraviolet radiations.
  • the second coating is made in concrete, constituted by selected shape, mass and volume aggregates, with no fines in order to have micropores in its mass and, in this way, make it possible that water may pass throughout it in all directions.
  • the third coating is constituted of an insulating material, resisting freezing-defrosting, with a density lower than 35 kg/m 3 , with a thermal conductivity lower than 0.04 w/m.C, with a compression resistance higher than 3 kg/m 2 , with a low water absorption lesser than 0.2% in volume, lacking or nill capillarity, good shape stability and hard to burn.
  • the insulating and draining pavement performed with this slab is very light since in its context it only weighs one fourth of a conventional pavement, which implies a significative reduction in the dead weight it must be supported by forgings and structures.
  • the thermal resistance may be modified by simply altering the thickness of the insulating coating although on its lesser thick thickness it provides the cover with a thermal protection similar to that provided by a 5 centimeter thick cork coating.
  • the resulting pavement is very resilient, since the anchoring material is being placed in every slab perimeter and, as such, an expansion joint is formed and, therefore, each slab freely moves with independence from all others thus accomodating itself to the support thermophysical motions.
  • the insulating coating supporting this paving slab has a perfect dimnmensional stability which avoids thermal bridges, since although the lineal dilatation coefficient in the insulating basis is of 0.07 mm/mC, this thermal movement is reduced by the intimate linking between the concrete coatings, and therefore the pavement thus obtained is practically stable.
  • the constructive solution obtained with this slab is very economical in regard with any other traditional solution due to the saving obtained in the materials motion and raising up to the cover, as well as due to the saving in the structure since the load upon the forging may be reduced due to the elimination of some critical points in the waterproofing and due to the fastness and easiness in the installating thereof since it is only required to manipulate one single piece.
  • the side step formed by offsetting the concrete coatings in regard with the insulating coating allows that the paving slab be overlapped onto the contiguous one; thus improving the pavement stability facing the suction of the eventual hurricane winds, since all slabs are assembled among them.
  • the concrete coatings are somewhat smaller than the insulating coating, when placing it they are separated by some millimeters, with which it is obtained that the insulating coatings be at all times in close contact, thus avoiding that thermal bridges may build up, and as such favouring, with its grooves, the rainfall water to pass to the pavement inside.
  • This pavement slab is also provided to be installed in slanted flaps, loose by itself, that is with no anchoring materials, providing that the first slab row rests on a support.
  • the paving slab complies in this case several functions:
  • the paving slabs being the subject matter claimed in this present invention may also be rectangular, and in which the square formed by the concrete coatings is slightly offset in regard with the lower coating axis in order that every paving slab may show, once configurated, a "half-wood cut" edge in order that a slab may overlap the adjoining one thus obtaining an additional resistance against the wind.
  • the paving slab (1) is provided with a coating which gives shape to its surface (2) which has been made based in compact mortars having various textures.
  • the slab has been provided with an intermediate coating (3) which has been made based on concrete absolutely free of fines.
  • the paving slab (1) has finally been provided with a third coating which constitutes the insulating coating and which has been referenced under (4).
  • the upper coatings (2) and (3) which have been configurated based on concrete having different idiosyncracies are slightly offset in their context in regard with the simmetry axis existing in the lower coating (3) which, as it has been said above, constitutes the insulating coating itself.
  • the paving slab itself may be overlapped on two of its sides, while, in turn, the same paving slab (1) is overlapped by the other two of its sides on which the upper surface has been withdrawn to form a step (5) useful to perform the overlapping upon it.
