Definitions

  • the present invention relates to a set of honeycomb panels for producing covers and walls.
  • these sets of honeycomb panels can also be positioned vertically, to create perimetric buffers or dividers of a building structure or part of it, such as the walls.
  • the grooves and protuberances are adjacent and substantially extend for the whole surface of the panel, creating a corrugated conformation.
  • honeycomb panels Although they should be produced at a low cost, when these sets of honeycomb panels form covers, they must provide a high insulation with respect to both water and air infiltrations, in order to keep the area delimited by them as insulated as possible from the outside.
  • FR-A-2401288 very simply discloses a joining system between panels created by means of an outer metal shell containing an expanded product.
  • facing ends of two coupled panels composed of the material of the outer shell, are curved and/or wound over each other to form the junction.
  • An insulating tape or sealing tape is inserted between the parts of the shell to improve the coupling and seal. This technique can certainly not be used in the case of honeycomb panels.
  • the panels are in fact produced with an outer sheet containing an insulating core, such as polyurethane foam.
  • an insulating core such as polyurethane foam.
  • US-A-4759165 discloses a set produced by coupling corrugated metal panels with shaped ends. One end of these metallic panels comprises a sealing washer in one of its curved portions, assembled at the moment of production of each panel, before forming the curved end. In any case, the curved portion is shaped so as to hold the washer and it occupies the whole curved portion. Again, this application cannot be used in the case of honeycomb panels.
  • US-A-3841094 illustrates a panel structure in which an insulating or sealing material in inserted in spaces created between the panels only at the moment of assembly.
  • the panels are panels made of an extruded plastic material in a single piece, without any outer metallic shell and without insulating material immersed in the interior, where they are produced directly in the extrusion phase of the honeycombs.
  • the production of panels is normally effected by the extrusion of plastic material creating so-called honeycomb panels completely made of plastic material without the need for a filling material.
  • This production process which considerably simplifies the construction of panels, does not guarantee a perfect complementarity between the grooves and protuberances, with the result that both rainwater and the outside air can filter through by falling into the empty spaces created in the joining areas of two adjacent panels. Furthermore, even when the grooves and protuberances are complementary, water is still able to filter through between two adjacent panels, due to the capillarity.
  • GB 2 453 864 discloses a set of honeycomb panels according to the preamble of claim 1.
  • a general objective of the present invention is therefore to provide a set of panels of the honeycomb type comprising at least a first and a second adjacent panel which is capable of overcoming all the drawbacks of the known art.
  • a further objective of the present invention is to define a set of panels of the honeycomb type which provides a safe and stable seal between the panels directly in the joining phase of two consecutive panels forming a cover or wall.
  • Another objective of the present invention is to provide a set of honeycomb panels which guarantees a sealed fixing between consecutive panels also in the presence of blockage means between subsequent panels.
  • the sealing element consists of a flap arranged in a protruding and tilted position in the production phase with respect to the internal profile of the single honeycomb panel which is automatically positioned in a sealing arrangement between the two end portions of honeycomb panels when coupled.
  • the sealing element could (in certain applications) be applied during the extrusion phase of the honeycomb panel or in an immediately subsequent phase, before the extruded honeycomb panel is cooled.
  • the sealing element is situated in correspondence with an intermediate portion of the groove to protect it during the movement and transportation of the single honeycomb panels, therefore also in phases prior to their assembly and joining.
  • the sealing element in fact has such considerable dimensions and juts from the surface of the panel to such a great extent that there is the risk of its being damaged during the movement of the honeycomb panels by contact with the ground, a transport pallet or the like.
  • Positioning the sealing element in correspondence with the intermediate portion of a groove guarantees its protection during the movement of the honeycomb panel, as, when resting on the ground, for example, the sealing element remains protected by the shoulders of the groove.
  • sealing elements having a significant thickness can be adopted, to improve the seal between one honeycomb panel and another when the cover or wall has been assembled.
  • this shows a portion of cover 10 composed of two honeycomb panels 11 and 12.
  • honeycomb panels 11 and 12 are positioned adjacent to each other and are destined for being joined to each other in correspondence with end-sections.
  • the honeycomb panels 11 and 12 are shown in a non-assembled condition (i.e. not in contact) for a clearer reading of the drawing: in an operative condition of the cover 10, on the other hand, the honeycomb panels are close to each other.
  • the end-section of the first honeycomb panel 11 comprises a groove 14 and the end-section of the second honeycomb panel 12 comprises a protuberance 15 having a form which is substantially complementary to the groove 14 and destined for being housed in the latter when the honeycomb panels are in an operative or assembled condition.
  • the cover 10 also comprises a sealing element 13 applied in correspondence with an intermediate portion of the groove 14, thus providing the advantages discussed above and to which no further reference will be made.
  • the sealing element 13 has a substantially rectangular and curved transversal section and a thickness preferably ranging from 1 mm to 4 mm.
  • the sealing element 13 can be continuous and applied to the whole transversal length of the honeycomb panel 11, or non-continuous, even if, in order to obtain a better seal, the first solution is preferable.
  • the sealing element 13 is applied after the production phase (for example by extrusion) of the honeycomb panel 11 on which it is applied, or by gluing, but in any case before it leaves the factory.
  • the sealing element 13 is advantageously composed of a thermoreactive material (also called hot-melt) which is deposited in the molten state onto the surface of the honeycomb panel 11 in the form of the sealing element 13, in order to avoid a preliminary gluing operation which would prolong the production times.
  • a thermoreactive material also called hot-melt
  • the sealing element 13 is composed of a simple curb (having a predetermined form and dimensions) which is applied in the molten state onto the surface of the honeycomb panel 11, where it reacts, solidifying and creating the sealing element 13 itself.
  • thermo-adhesive polyurethane for example of an aliphatic or aromatic nature such as HDI or IPDI and polyols of a polyester, polyether, caprolactone or polycarbonate nature
  • a material of an acrylic nature based on mixtures of polymers, copolymers or thermopolymers with an acrylic functionality that can comprise the use of hydrogenated hydrocarbon resins, terpene phenolic resins and polyterpene resins or structuring polymers such as PMMA, MBS, SIS/SBS, EVA or TPE, depending on the requirements.
  • the sealing element 13 can also be applied in an expanded version, for example by introducing into the formulation, one or more suitable additives of the type generally known to experts in the field.
  • a further alternative consists of forming the sealing element as a tubular element or hollow element which allows a crushing effect and therefore a better seal between the honeycomb panels where it is applied right from the production, as can be seen hereunder.
  • the application may also be effected during the extrusion phase of the honeycomb panel 11, using the heat supplied in this last phase to cause expansion of the sealing element 13 following the production (under the action of heat) of gas which creates microbubbles, giving the sealing element 13 the desired expanded conformation.
  • the sealing element 13 due to the thickness of the sealing element 13 and its positioning, it also exerts an important soundproofing and prevention function of assessment noises of the cover or wall: it guarantees, in fact, that two adjacent honeycomb panels 11, 12 are mainly, or solely, in contact by the interpositioning of the sealing element 13.
  • the damping action of the latter also provides benefits in the case of atmospheric precipitations (rain, hail) on the cover: it prevents the honeycomb panels 11, 12, in fact, from causing an unpleasant percussive noise or, more generally, this noise is reduced.
  • honeycomb panels 11, 12 are concerned, these can generally have various conformations.
  • the panels 11, 12 are honeycomb and undulating.
  • a series of variants are available, illustrated in the enclosed figures.
  • FIG. 2 has a covering unit 20 comprising two honeycomb panels 21, 22 having a corrugated form with straight sections.
  • a sealing element 23 analogous to that described above is situated in correspondence with a groove 24 of a honeycomb panel 21, destined for entering into contact with a protuberance 25 of the other honeycomb panel 22 and creating a seal with it.
  • honeycomb panels 21 and 22 are of the corrugated type.
  • sealing element 23 has the form of an actual curb with a semicircular section, rather than flattened, which can also be used in the first example shown in Figure 1 and viceversa.
  • the material and type of application of the sealing element 23 are analogous to what is specified above.
  • honeycomb panels 31 and 32 are respectively provided, one with a groove 34, and the other with a protuberance 35, analogously to the honeycomb panels 21 and 22 described above, with the addition of a clamping screw 38.
  • a sealing element 33 is positioned in correspondence with fixing means, for example a screw 38, which engages the end-sections of the honeycomb panels 31 and 32, fixes them to each other and possibly also fixes them to an optional supporting wall P.
  • the material and type of application of the sealing element 33 are analogous to what is specified above and therefore no further reference will be made to them, except that it should be noted that its positioning in correspondence with the fixing means 38 allows its preliminary compression providing a better airtight and waterproof seal.
  • FIG. 4 shows a honeycomb panel 41 of a covering unit 40. Also in this case, the important features are the same as those described above for the covers 10, 20, 30 and therefore no further reference will be made to these. It should also be noted that, in this case, a throat 47 is situated in correspondence with a groove 44 of the honeycomb panel in the extrusion or formation phase, in which a sealing element 43 is partly housed in order to prevent its undesired displacement during movement, stacking or installation and a stable positioning.
  • the throat 47 has a substantially "V"-shaped transversal section, but it may equivalently be rounded, rectangular or have other forms.
  • the "V"-shape of the throat 47 is particularly suitable for use in combination with a sealing element 43 having a substantially semi-circular section.
  • the sealing element can have any section: in the case of a covering unit 50 ( Figure 5 ) produced with honeycomb panels or corrugated sheets 51, of which only one is illustrated, a groove 54 could have a bottom with a flat section (see Figure 5 ).
  • the sealing element 53 advantageously has a rectangular section which extends to substantially occupy the whole extension of the flat bottom part of the groove 54, thus exploiting the maximum surface available and improving the seal.
  • sealing elements can also be envisaged, alternatively or in combination, as shown in the example in Figure 6 .
  • part of a covering unit 60 can be observed, comprising a honeycomb panel 61 in a groove 64 in which two sealing elements 63 and 63A are positioned.
  • Said sealing elements 63 and 63A in this case, have a substantially semi-circular section, but they can also have other sections.
  • sealing elements 53, 63, 63A are produced analogously to what is indicated above and no further reference will be made to this.
  • a first honeycomb panel 71 comprises two sealing elements 73, 73A positioned in a groove 74 and an additional sealing element 73B positioned on a protuberance 75 of a second consecutive honeycomb panel 72 and partially superimposed and facing in the terminal part.
  • the additional sealing element 73B is positioned on a honeycomb panel 72 so that with the covering unit 70 assembled, it is in an offset position with respect to the two facing sealing elements 73, 73A of the other honeycomb panel 71.
  • sealing element 73, 73A there can obviously be only one sealing element instead of two sealing elements 73, 73A, without substantially changing the arrangement.
  • additional sealing element 73B, as also the sealing elements 73, 73A, is also produced analogously to what is indicated above.
  • Figures 8 , 9 and 10 illustrate an embodiment of a section of a covering unit according to the present invention in a non-assembled condition of the honeycomb panels, in a partially assembled condition, and finally, in a completely assembled condition.
  • a set of honeycomb panels for a cover 120 comprises at least two honeycomb panels 121, 122 having a corrugated form with straight sections.
  • this covering unit there is a sealing element 123 in correspondence with a groove 124 of the honeycomb panel 121, destined for entering into contact with a protuberance 125 of the honeycomb panel 122 and creating a seal with this.
  • This sealing element 123 is produced in the form of a flap positioned in a part 123A integral with the groove 124 of the honeycomb panel 121, and in a detached part 123B, protruding and tilted, again with respect to the groove 124.
  • said flap-shaped sealing element 123 is, in the production phase, at least partially protruding and detached from the groove 124 of the single honeycomb panel 121.
  • the flap-shaped sealing element 123 is automatically positioned in a sealing arrangement between the two end-portions of honeycomb panels coupled with each other.
  • any possible deficiencies in the complementarity (visible in Figure 9 ) between the two adjacent honeycomb panels 121, 122, superimposed at least in their end section, can be recovered.
  • a perfect sealing arrangement of the two honeycomb panels 121 and 122 is therefore obtained, forming a covering unit, as shown in Figure 10 .
  • fixing means for example, in the form of a screw 138, which engages end-sections of the corrugated honeycomb panels 131 and 132, passing through them and into a flap-shaped sealing element 133, such as that described above.
  • the honeycomb panels 131 and 132 are respectively provided with a groove 134 and a protuberance 135 analogously to the honeycomb panels already described, with the addition of a clamping screw 138.
  • the flap-shaped sealing element 133 is situated in correspondence with the clamping screw 138 and therefore engages the end-sections of the honeycomb panels 131 and 132, connects them to each other and possibly connects them to an optional supporting wall P.
  • the clamping screw 138 passes into a part 133A of the flap-shaped sealing element 133, integral with the groove 134 of the honeycomb panel 131.
  • the flap-shaped sealing element 133 with its two integral 133A and protruding 133B parts from the groove 134, is automatically positioned in a sealing arrangement between the two end-portions of honeycomb panels 131, 132 coupled with each other.
  • Figures 12 and 13 which, with reference to 80, illustrate a part of an overall covering unit, also functioning as a vertical wall for particular applications.
  • This wedge-insertion consists of a groove 84 positioned in the honeycomb panel 81 and a protuberance 85 which extends or juts from the honeycomb panel 82.
  • a sealing element 83 is applied to the interior of the groove 84, in a substantially intermediate position to the latter.
  • the protuberance 85 is destined for cooperating with the groove 84 to form an actual wedge-insertion, as shown in the assembled condition shown in Figure 13 .
  • the groove 84 and protuberance 85 do not have a perfect complementary form, but an insulating chamber 90 is defined between the two, in a coupled condition (see Figure 13 ), forming a horizontal cover.
  • This insulation chamber 90 serves for separating the facing walls of the panels 81 and 82 to contribute to preventing a capillarity phenomenon, should water succeed in penetrating this area.
  • the sealing element is produced as a tubular or hollow element as shown for example in Figures 14 , 15 and 16 , which are similar in their general conformation to examples already illustrated, and show said tubular or hollow sealing element 93.
  • the tubular or hollow sealing element 93 is positioned in the groove 24 of the panel 21, whereas in Figures 15 and 16 it is positioned in the groove 84 of the panel 81 and is shown in both a non-assembled and assembled condition on both the bottom and on a side of the groove 84.
  • Figure 16 illustrates a crushing effect of the tubular and hollow sealing element 93 with an improved seal between the honeycomb panels where it is applied right from their production.
  • the sealing element 13,23,33,43,53,63,63A,73,73A,73B,83,93,123,123A,123B can be completely transparent or at least partly coloured to assist a user during assembly, especially when the panels 11,21,31,41,51,61,71,81,121 and/or 12,22,32,42,52,62,72, 82,122 are at least partly transparent or translucent.
