Definitions

  • the invention relates to insulating panels used to construct walls, roofs and the like in civil, industrial or other kinds of building structures.
  • these panels have a composite or "sandwich” structure comprising an insulating core arranged between two walls which define the outer faces of the panel; the insulating material is generally a polyurethane foam or the like (but may also be mineral wool or some other insulating material), while the outer faces are in most cases made of sheet metal.
  • the insulating material is generally a polyurethane foam or the like (but may also be mineral wool or some other insulating material), while the outer faces are in most cases made of sheet metal.
  • the outer faces are profiled with ribs; these ribs may have numerous designs and for a more detailed description of one of them, reference can be made to the disclosure of European patent applications Nos. 682159 or 995594.
  • the present invention relates to insulating panels with ventilation channels.
  • this latter document describes a panel wherein a hollow space is defined between the trapezoidal ribs of the outer sides and the material of the insulating core: a circulation of hot air rising upward can be established inside this hollow space, thereby producing a ventilation system capable of removing moisture and/or heat.
  • Reference can be made, for example, to roofs built by assembling panels of this type in an inclined position, so that the heat due to the sun irradiation can be removed by means of convection, by air which rises up along the hollow spaces.
  • the abovementioned British prior document does not explain how the panel refe ⁇ ed to can be produced on an industrial scale; however, since the material used for the insulating core is a rigid or semi-rigid foam of polyurethane, polyisocyanate or polystyrene, it may be infe ⁇ ed that manufacturing of the panel is performed by assembling the rigid or semi-rigid layer of foam with the two outer faces.
  • the technical problem underlying the present invention is that of improving this state of the art: namely, the invention aims at providing a ventilated panel with an insulating core which includes a layer of polymer foam, which may be manufactured continuously, in a manner similar to that which occurs for normal insulating panels.
  • the invention further comprises a process for manufacturing this panel, whose features are also stated in the claims.
  • FIG. 1 shows respective panels according to the invention
  • Fig. 3 is a diagram of the plant for the continuous manufacturing of the panel according to Fig. 1 ;
  • Fig. 4 is a detail of the plant in Fig. 3.
  • numeral 1 denotes overall an insulating panel for roofs of buildings, manufactured in accordance with this mvention.
  • Such panel comprises an upper face 2 and a bottom face 3 opposite each other and between which an insulating core 4 formed by polyurethane foam or other expanded resin is arranged; the upper face 2 forms the surface of the panel which is exposed externally when the roof is laid in place, while the bottom face 3 forms the surface directed towards the inside of the under-roofing.
  • Both faces of the panel are made of profiled sheet metal, the upper face being profiled in a more marked manner while the bottom face is only "micro- ribbed", namely is lightly ribbed to allow it to be bent as will be described more fully below.
  • a sheet 5 of aluminium or other equivalent material is applied onto the upper face 2 and adheres to its flat portions, sealing underneath the high ribs 6 with a trapezoidal shape projecting from the said face: these ribs are internally hollow and therefore form ventilation channels for the panel as explained farther above.
  • secondary ribs 7, lower than the high ones and serving as air flow channels, are also present on the upper face 2 of the panel.
  • the bottom face 3 is "micro-ribbed", i.e. it is provided with shallow grooves 8 which ensure that it remains plane during processing.
  • the panel 1 is manufactured in a continuous manner using the plant shown in Figure 3, which comprises two reels 10 and 11 from which respective metal strips 12 and 13 are unwound, the first strip being fed at a lower level than the second strip.
  • the strips 12 and 13 have the function of respectively forming the upper face 2 and the bottom face 3 of the panel 1, likewise it occurs in the production of conventional panels; the different numbering is intended to indicate the difference between the semi-finished product formed along the plant and the finished product with its components shown in Fig. 1.
  • the higher ribs namely the ribs 6 and 7 of panel 1, are formed on the strip 12 which advances horizontally at a lower level.
  • the strips 12, 13 therefore pass into respective profiling machines 14, 15 where the ribs 6, 7 are formed on the first strip, while the lightly ribbed grooves 8 are formed on the second strip.
  • a gluing station 16 Downstream of the profiling machine 14 there is a gluing station 16 inside which a foil 18 of aluminium is fixed onto the profiled strip 12; the sheet 5 of the finished panel shown in Fig. 1 is obtained from the foil 18, which for this purpose is unwound from a reel 19 and fixed to the strip 12 using a suitable adhesive.
  • the foil could consist of a material other than aluminium and also be of non-metallic nature, such as a plastic film or the like; it must also be mentioned that the foil or thin sheet may be fixed in a way other than gluing, for example in the case of a metal sheet it would be possible to use spot welding or continuous-seam welding.
  • the expansion step is performed in a continuous press 25 which is known per se and wherein the continuous semi-finished product formed by the strip 12 (together with the foil 18) and strip 13, with the resin applied therein, passes between two continuous surfaces 26, 27, arranged one below and the other above; these surfaces are formed by transverse elements 28 connected together in an articulated manner and having superficial reliefs 29 (in Fig. 4 only those of the upper surface are visible), which engage inside the grooves 8 (or the ribs 6, 7 of the strip 12).
  • the continuous semi-finished product is cut by a shearing device 33, thereby obtaining panels 1 of the desired length.
  • the sheet 5 applied onto the upper face 2 performs a dual function: the first one is that of sealing the ribs 6 and 7, thereby defining the air flow channels inside the panel, whereas the second one is that of forming a partition which prevents the resin from expanding inside the ribs.
  • the present invention allows therefore to manufacture insulating panels carrying out the steps of applying the resin and subsequent expansion thereof directly between its profiled faces 2 and 3, instead of having to assemble the latter with a rigid or semi-rigid core of expanded resin formed separately beforehand, as it occurs in the prior art considered.
  • the manufacturing time may be reduced, in particular if the panel so configured is manufactured continuously as explained above.
  • the panel 1 is suitable for being produced also with pre-existing plants, since the operating cycle described above does not require particular modifications to the production lines used for conventional panels: basically it is only a matter of adding the station 16 for applying of the foil 18.
  • the sheet 5 applied onto the upper face 2 of the panel may be made of various materials; it must be stressed, however, that this sheet could also be advantageously formed by a layer of mineral wool, as shown in Figure 2.
  • the panel thus obtained has the same ventilation properties and the same advantages as the preceding panel, with an improved fire resistance in view of the presence of the mineral wool.
  • This panel may also be manufactured in a similar manner to that already explained, using mineral wool wound on reels or fed continuously.
  • the fire-prevention properties of such a panel could also be improved by applying onto the upper face 2 a sheet of aluminium, as referred to above; in this way a panel having characteristics formed by a combination of those of the individual panels shown in Figs. 1 and 2, would be obtained.
  • a panel so constructed would be equivalent to those of the examples previously seen and would only require a minor modification to the gluing station 16 of the plant illustrated in Fig. 3, in order to be manufactured continuously.
