Definitions

  • Cladding processes are more and more used and appreciated to assume the external thermal insulation of facades. They in fact use standard elements associating an insulating panel and an often metallic facing, which can be mounted directly on the supporting structure without requiring a framework, which considerably simplifies construction.
  • the facing must provide mechanical strength at the same time as the protection of surfaces. Consequently, on the one hand the contact surfaces between the insulating panel and the metal of the facing are large, which does not allow the grooves to be given sufficient dimensions, and on the other hand the facing of each element is firmly fixed to that of the adjacent element, which makes it difficult to form openings allowing ventilation. The water vapor coming from the housing therefore tends to condense on the internal face of the facing without being able to escape.
  • the object of the present invention is to remedy drawbacks by producing a covering element with a ventilated air knife, of simple and robust construction.
  • the subject of this invention is in fact a covering element comprising a thermally insulating panel made of a rigid material, one of the faces of which carries regularly spaced bosses and a facing plate made of a rigid and mechanically resistant material, such as asbestos cement or polyester concrete, which is glued to the bosses and defines with the panel an air space, characterized in that the panel only has a few bosses spaced apart from each other in both directions of the insulating panel, and occupying only about 20% of the surface of this panel, and in that the facing plate is shorter than the insulating panel, so that it cannot come into contact with the facing plate an element juxtaposed and that the vertical joint between these elements remains open, which allows ventilation and equalization of the air pressures on each side of the facing plate.
  • a thermally insulating panel made of a rigid material, one of the faces of which carries regularly spaced bosses and a facing plate made of a rigid and mechanically resistant material, such as asbestos cement or polyester concrete, which is glued to the bosses
  • the facing plate extends beyond the lower edge of the panel while the thickness of the latter gradually increases in the direction of this lower edge, so that there automatically remains a space between the upper part of an element and the extension of the facing of an element which is superposed on it.
  • the rigidity of the components of the covering element associated with their particular shape makes it possible not only to establish, without the use of framework or the like, a large air circulation space behind the facing, but to form and maintain open joints constantly putting this space in communication with the atmosphere, at its lower part as at its upper part, and even on its lateral faces, and thus ensuring ventilation.
  • the covering element comprises, in the usual manner, a thermally insulating panel, preassembled to a facing plate 2 and is intended to ensure the thermal insulation of a front wall in combination with other similar elements, juxtaposed and superimposed.
  • the insulating panel 1 has a rectangular shape and is made of a rigid waterproof material. It has, on one of its faces, a certain number of elongated bosses 4.40, which are directed transversely to this face and spaced from one another, and on which the facing plate is fixed 2.
  • the thickness of all the bosses 4, 40 is sufficient to allow ventilation and the flow of condensation water between the panel 1 and the facing plate 2. It is, for example, of the order of 15 mm.
  • bosses 4 are arranged in two rows adjacent respectively to the upper edge and the lower edge of the panel 1.
  • the bosses of these two rows are similar but inverted and have, in look of the facing plate 2, a trapezoidal surface.
  • bosses of the two rows may however be advantageous to join to form, as shown in fig. 6, a single row of long bosses 40.
  • the bosses 40 start from the upper edge to pass through substantially the entire face of the panel and have a substantially trapezoidal surface widening downwards.
  • bosses or other arrangements can be used.
  • intermediate bosses spaced at their two ends of the edges of the panel can be provided.
  • These intermediate bosses 6, 46 also have an elongated shape. They can simply have a trapezoidal surface like the bosses 46 in FIG. 6, or have another shape and present for example a diamond-shaped surface, like the bosses 6 of FIG. 1.
  • the total surface of the bosses is only a small portion of that of the corresponding face of the panel 1.
  • the bosses occupy approximately 20% of the face of the panel.
  • the facing plate 2 which also has a rectangular shape, is fixed to the bosses 4 and 40, for example by gluing.
  • This plate is made of a rigid material having good mechanical resistance, for example asbestos cement or polyester concrete.
  • the width of the plate 2 is slightly less than that of the panel 1, as shown in FIG. 2, so that when several similar elements are placed side by side, the facing plates 2 cannot come into contact on their vertical edges 8.
  • the panel 1 comprises, on its two vertical edges a groove in the form of a rebate, respectively 10 and 11, the two rebates being offset relative to each other.
  • the rebates fit together and the insulating panels come into close contact.
  • the space 12 left free between the face of the panel 1, the bosses 4 and the facing 2, on the other hand is in communication with the outside via the open joint 14, between the lateral edges 8 of the two facing plates.
  • the space 12 extends over the entire surface of the panel, so that the element comprises a relatively thick air gap, delimited by the panel 1 and the bosses 4 on the one hand, and the internal face of the plate facing 2 on the other hand.
  • This blade is vented at its two ends by the open joints 14.
  • the insulating panel 1 has a thickness which is progressively increasing, from its upper part to its lower part, as shown more particularly in FIG. 3, while the facing plate 2 extends beyond the lower edge 16 of the panel 1, that is to say of the widest edge of this panel. Consequently, when two elements A e D are placed one above the other, the extension 21 of the upper facing covers the upper part of the element A placed below. However, given the shape of the insulating panel 1, the two superposed elements A and D can penetrate one inside the other without the two facing plates coming into contact. On the contrary, an open joint 23 is formed between the facing plates of the elements A and D, as shown in FIG. 4.
  • the upper and lower edges of the panel 1 have a form of rebate in the opposite direction, so that they can fit into each other in the same way as the vertical edges.
  • the rebate 18 of the upper edge is open in the direction of the front wall, that is to say in the direction opposite to the facing plate 2, so that the flange 20 which delimits it in the vicinity of this facing plate may constitute a stop for retaining the rib 24 of the lower edge of the superimposed element D.
  • the lower and upper sections have, in the vicinity of the bosses 4, an inclined face 26 directed downwards, these two faces being parallel to each other.
  • the elements can thus be superimposed and in close contact along their respective horizontal edges.
  • Their smooth waterproof face 25 is applied against the wall by means of screws passing through holes in the facing plate and bosses 4 in the upper row, to penetrate the front wall.
  • the screws 27 thus hold both an element A and the lower part of the element directly superimposed D.
  • the holes 29 for the passage of the screws are provided at the upper part of the bosses 4, 40 and of the facing plate. 2, which allows the head 28 of the screws to be hidden by the extension 21 of the facing of the upper element.
  • a facade wall cladding is thus obtained which is securely fixed and does not risk being damaged or torn off as a result of bad weather.
  • the air gap 12 formed between the insulating panels 1 and the facing plate 2 is always in communication with the outside, both at its upper part, at its lower part and on its two lateral edges. The air space is thus largely ventilated.
  • the panel 1 also includes a decompression groove 30 in each of its vertical sections, as well as a horizontal groove 32 in its lower section.
  • the vertical grooves 30 are in communication with the ventilated air knife 12 at their lower part by the groove 32 and by transverse grooves 36 formed at regular intervals along the length of the panel, between the groove 32 and the air knife 12 .
  • the calories transmitted from the outside to the facing that is to say the calories due to solar radiation and captured by the facing, are evacuated by the ventilated air space circulating behind this facing, which avoids their transmission to panel 1 and, consequently, to the facade.
  • a hook 38 in S is fitted on the lower edge of the extension 21 of a facing plate and on the upper edge of the facing plate 2 of the element directly below, which keeps the two elements close to each other without closing the seal 23.
