Definitions

  • the present invention relates to a prefabricated insulating panel for cladding buildings, an insulating cladding obtained therefrom and a corresponding manufacturing method.
  • thermal insulation technique known as external insulation has been known for some time, that consists in externally cladding the building structures.
  • the cladding is, generally, obtained directly from the construction site covering the supporting surfaces to be insulated, appropriately prepared, with slabs made of insulating material, by way of gluing and fixing with nails or plugs. The exposed surfaces of such slabs are then smoothed and a net is applied that acts as reinforcement for the adhesion of one or more finishing layers.
  • a system for cladding building structures that uses a plurality of prefabricated insulating panels, arranged so that they are mutually adjacent and in reciprocal contact and fixed to the structure by way of plugs to obtain a modular cladding.
  • Such panels are, substantially, constituted by a structural slab made of thermally insulating material, by a net laid flat and glued to such slab and by a layer of plaster spread on the net and firmly attached to the structural slab.
  • the structural slab has a rectangular shape and is provided with a protruding rib that runs along two consecutive sides and a receiving groove, having a profile that is complementary to such rib, that runs along the other two sides. When laying panels, each panel is positioned with the corresponding protruding rib accommodated in the receiving groove of the adjacent panel.
  • the flat net is provided with a flap which protrudes from the shape of the slab at two consecutive sides and the slab has an exposed band, free from the net and plaster, at the other two sides. While the panels are being laid, each panel is positioned with the corresponding protruding flap leaning against the exposed band of the adjacent panel; the free bands on which the protruding flaps of the net are superimposed are finally covered with a layer of plaster to obtain a continuous cladding.
  • interlocking reference system of adjacent panels implicates knowing the correct orientation and subsequent positioning, which slows down the operation of laying the panels.
  • the prefabricated panels must be cut to reduce the size while they are being laid, it is necessary to cut a portion of the panel at the sides provided with the protruding net flap, in order to allow the correct positioning and fixing to the adjacent panels.
  • such panels provide for the insertion of plugs for fixing to the building structure at certain positions, which are not always available when the panels are cut to size, which can make fixing the panels to the building structure difficult.
  • the aim of the present invention is to eliminate the above mentioned drawbacks of the known art, by providing a prefabricated insulating panel for cladding buildings that allows to obtain a cladding whose exposed surface is perfectly flat and without discontinuity, in order to facilitate the subsequent application of the desired finish.
  • an object of the present invention is to provide a prefabricated insulating panel that can be laid in any orientation, regardless of the positioning of the adjacent panels.
  • Another object of the present invention is to provide a prefabricated insulating panel that is easy to lay even when cut to size, without needing any particular solutions.
  • Another object of the present invention is to provide a prefabricated insulating panel that can be used for the cladding of any building surface and, in particular, to provide cladding for external insulation.
  • Another object of the present invention is to obtain a cladding that guarantees a correct thermal insulation for the buildings on which it is used and that makes it easy to apply the subsequent layers of finish and with high quality results.
  • Another object of the present invention is to provide a prefabricated insulating panel that is easy and fast to manufacture in a factory, with a limited number of production steps, and that can be easily stored and transported.
  • Another object of the present invention is to provide an insulating panel that is simple, relatively easy to provide in practice, safe and efficient in use, as well as of low costs.
  • the present prefabricated insulating panel for cladding buildings comprising a structural slab made of thermally insulating material and provided with a first and second face, which are mutually opposite, and at least one reinforcement element, which is associated and superimposed so as to cover said first face, the laying and exposed surfaces of said panel being formed respectively by the second face of the structural slab and by the reinforcement element, characterized in that said exposed surface is shaped so as to form at least one recessed band, which is arranged at at least one perimetric region and has a substantially lower thickness than the remaining portion of said panel.
  • the present insulating cladding for building structures characterized in that it comprises a plurality of panels according to the invention that are mutually juxtaposed so that their respective recessed bands are adjacent so as to cover at least a portion of the building, the means for fixing said panels to the building and the means for joining mutually adjacent panels, which fill said recessed bands so as to obtain an exposed surface without discontinuity.
  • the reference numeral 1 designates a prefabricated insulating panel for cladding building.
  • the panel 1 comprises a structural slab 2 made of thermally insulating material and provided with a first face and a second face, respectively 2a and 2b, which are mutually opposite and at least one reinforcement element 3 which is associated and superimposed so as to cover the first face 2a.
  • the exposed surface 1a and the laying surface 1b of the panel 1 are formed by, respectively, the reinforcement element 3 and the second face 2b.
  • the exposed surface 1a is shaped to form at least one recessed band 4, arranged at at least one perimetric region where the panel 1 has a substantially lower thickness than the remaining portion of the panel.
  • the band 4 runs along the whole perimeter of the panel 1.
  • the exposed surface 1a can be shaped to form at least one recessed sector 5, at which the panel has a thickness substantially equal to the thickness at the recessed band 4.
  • Such sector 5 is positioned in the central area of the panel 1.
  • the structural slab 2 is provided with at least one material chosen from the group comprising polystyrene, polystyrene with graphite, polyurethane, rock wool, extruded polystyrene, wood fiber, cork, coconut fiber, hemp, and can be made by way of cutting to size or by pressing, according to the material used.
  • the reinforcement element 3 is shaped so that it mates with the first face 2a and covers it completely, so as to obtain a uniform exposed surface 1a.
  • the reinforcement element 3 is, preferably, constituted by an aggregated system of filaments and/or fibers to obtain a paper-like material, a fabric or a nonwoven fabric.
  • the reinforcement element 3 has the mutually opposite surfaces provided with geometric irregularities, not shown in the figures, that facilitate the adhesion to the structural slab 2 and to the layer of finish applied after the panels have been laid.
  • Such geometric irregularities can be of the type of through holes provided on the reinforcement element, or can be obtained by way of embossing.
  • the structural slab 2 can have at least one and more preferably a plurality of elongated notches 6 that affect a portion of the slab thickness so as to avoid deformation over time after it has been laid.
  • the structural slab 2 is rectangular in shape and is provided with a plurality of notches 6 arranged parallel to the short ends of the shape of the slab and distributed along its length.
  • the continuous layer 7, at the band 4 and at the sector 5 if provided, has a reduced thickness compared to the remaining portion of the layer, as the structural slab 2 has a substantially constant thickness.
  • the desired profile of the exposed surface 1a is provided by way of the shape of the continuous layer 7.
  • the structural slab 2 has the first face 2a shaped in such a way as to form the band 4 and the possible sector 5 and in this case the continuous layer 7 has a uniform thickness.
  • the panel 1 takes up minimal space within the shape of the structural slab 2 and can be easily stored and transported until it is laid.
  • a plurality of panels 1 should be arranged so that they are mutually juxtaposed with the respective bands 4 adjacent so as to cover at least one portion of a building to be thermally insulated.
  • the cladding 8 requires the use of means 9 for fixing the panels 1 to the building and means 10 for joining mutually adjacent panels 1, which fill the bands 4 so as to obtain an exposed surface 1a without discontinuity.
  • the joining means 10 must guarantee the insulation and the flatness of the exposed surface of the cladding 8.
  • the joining means 10 ( Figure 7 ) provides for the use of pieces of adhesive tape made of glass fibers or strips of reinforcement net 11 cut to size to cover the bands 4 so that two by two are adjacent.
  • the joining means 10 further comprise at least one layer 12 of filler material, such as mortar or plaster, for covering the adhesive tape or the reinforcement net 11 to obtain a cladding 8 whose exposed surface is continuous and flat.
  • the fixing means 9 are constituted by plugs or nails for the thermal insulation of a conventional type that can, conveniently, be positioned along the bands 4 and at possible sectors 5.
  • the fixing means 10 can affect one single panel, or can be positioned at the contiguous sides of two adjacent panels 1 or where three or four mutually juxtaposed panels 1 come into contact.
  • the plugs or nails 9 positioned along the bands 4 are superimposed by the joining means 10, the layer 12 being conveniently smoothed at the heads of the plugs or nails to obtain a continuous and flat exposed surface of the cladding 8.
  • Means 13 for covering the relative plugs or nails 9 are provided at the sectors 5 ( Figure 8 ) to obtain a cladding 8 with a uniform thickness, and consist of a layer of mortar or plaster that fills such sectors.
  • Figures 7 and 8 show claddings 8 using different arrangements of the panels 1.
  • the panels 1 can be manufactured in factories or other dedicated areas and transported to the construction site ready to be laid.
  • the manufacturing method of a panel 1 comprises the steps of:
  • the above mentioned step of shaping comprises a preliminary pressing step ( Figure 11 ) of the structural slab 2 to shape the first face 2a according to the profile that mates with the profile of the exposed surface 1a and a final pressing step ( Figure 13 ) to compact the structural slab 2, the continuous layer 7 and the reinforcement element 3 which are mutually superimposed.
  • the continuous layer 7 has a substantially constant thickness.
  • the step of shaping ( Figure 10 ) consists of pressing the structural slab 2, the continuous layer 7 and the reinforcement element 3 which are mutually superimposed to shape the continuous layer 7 according to the profile that mates with the profile that one wants to confer to the exposed surface 1a.
  • the structural slab 2 maintains a substantially uniform thickness.
  • the invention thus described achieves the intended aims and in particular the fact is underlined that the panel according to the invention allows to obtain cladding whose exposed surfaces are uniform and flat, ready for the application of further layers of finish.
