Definitions

  • the present invention relates to a roofing joint covering, in particular for covering the junction between a chimney and at least one slope of a roof above which the chimney rises, as defined in the preamble of claim 1 .
  • One of the essential aims of the present invention is to remedy the aforementioned drawbacks and to propose a joint cover, the installation of which is very easy and effective and suitable for practically any type of joint at the level of the roof.
  • the joint cover consists of a strip of malleable material folded around an axis parallel to its longitudinal direction at an angle ( ⁇ ), so as to form two wings s' extending side by side, at least one of these wings having a succession of folds, preferably rounded, extending in its longitudinal direction over at least a certain part of its length, at least part of these folds being deformable in this direction longitudinal.
  • the invention also relates to a method for implementing this joint cover, in particular for covering the junction between a chimney and at least one slope of a roof above which the chimney rises.
  • This process is characterized by the fact that the joint cover is placed in the angle formed by the chimney and the slope of the roof by applying one of the wings against the chimney and the other wing against the slope by deploying the folds of the latter at the corner of the chimney so as to surround these corners.
  • the two wings of the strip made of a malleable material have a succession of substantially identical folds in their longitudinal direction, a determined fold of one of the wings extending in the extension of a fold of the other wing.
  • the successive folds are supported substantially one against the other.
  • the above malleable material is based on lead.
  • Figure 1 is a schematic perspective view of part of a first embodiment of a joint cover according to the invention.
  • Figure 2 is a longitudinal section of this embodiment.
  • Figure 3 is a longitudinal section similar to that of Figure 2, in which however the folds are applied firmly against each other.
  • Figure 4 is a perspective view of this first embodiment in a straight deployed state.
  • FIG. 5 is a perspective view of part of this same embodiment in a deployed state in the form of a curve.
  • Figure 6 is a partial schematic perspective view of the application of this embodiment of joint cover at the junction of a chimney with a roof slope.
  • Figure 7 is a schematic view of a device for manufacturing the joint cover according to the invention.
  • the invention relates, in general, to a roofing joint covering, in particular for covering the junction between a chimney and at least one of the slopes of a roof above which the chimney rises.
  • a joint cover can also be called "flashing".
  • This joint cover or flashing consists of a strip of a malleable material, such as lead, a product based on concrete or a suitable plastic material, comprising two wings extending side by side forming an angle between them. less than 180 °, preferably of the order of 90 °, at least one of these wings having a succession of folds in its longitudinal direction over at least part of its length, so as to allow deformation of this wing by a stretching it by partially or fully deploying at least part of certain folds.
  • a malleable material such as lead
  • a product based on concrete or a suitable plastic material comprising two wings extending side by side forming an angle between them. less than 180 °, preferably of the order of 90 °, at least one of these wings having a succession of folds in its longitudinal direction over at least part of its length, so as to allow deformation of this wing by a stretching it by partially or fully deploying at least part of certain folds.
  • Figure 1 is a schematic perspective view of a particular embodiment of the joint cover 5 according to the invention.
  • This joint cover 5 is formed of a continuous strip of a malleable material folded in an L shape in its longitudinal direction so as to thus obtain two wings 1 and 2 extending side by side in the longitudinal direction 12 of this strip and forming between them an angle ⁇ of the order of 90 °.
  • Each of these wings 1 and 2 has, in their longitudinal direction, a succession of identical folds.
  • a determined fold 3a of one of these wings 1 and 2 extends in the extension of a fold 3a 'of the other wing so as to thus obtain a substantially continuous transition zone 15 between the two wings 1 and 2 according to a rounded corner.
  • a slight spacing 3 ' may persist between two successive folds 3a and 3b, as shown in FIG. 2.
  • the width of this spacing is a function of the 'thickness and rigidity of the strip of malleable material as well as the technique applied for the manufacture of the joint cover.
  • the successive folds 3a, 3b, 3c can be applied one against the other, before the use of the joint cover. This can have a certain advantage as regards the storage and transport of joint covers thus occupying a minimum volume.
  • the thickness of the malleable strip "e p " and the height or amplitude "e” of the folds 3 can be very varied, in particular depending on the material used and the intended use of the joint cover.
  • the height "e" of the folds is advantageously between 3 and 10 times this thickness.
  • the width of at least one of the wings of the strip of malleable material is between 3 and 15 cm.
  • the width of one of the wings can be between 1.5 times and 4 times the width of the other strip.
  • advantageously is used joint covers with wings 1 and 2 of identical widths (l 1 l 2 ).
  • FIG. 4 is an illustration of a rectilinear deployment of the joint cover according to the invention
  • FIG. 5 schematically shows a deployment in a curve, for example at the location of a chimney corner.
  • Figure 6 shows an assembly of the joint cover 5, as shown in Figure 1, around a chimney 6 rising above the slope 7 of a roof.
  • This joint cover 5 consists of a single continuous piece, unlike what is the case for known conventional joint covers which are formed from a succession of separate pieces of zinc or lead bent at right angles and arranged one after the other with partial overlap.
  • the joint cover is placed in the angle formed by the chimney and the roof slope by applying one of the wings 1 against the chimney and the other wing 2 against the slope by deploying the folds. 3 of the latter at the corner of the chimney so as to surround these corners.
  • joint covers according to the invention can thus be cut to the desired length.
  • the joint covers have at each of their ends a non-pleated zone 16 thus allowing the overlapping of two successive joint covers in the case of covering relatively long junctions.
  • the length of a joint cover can be very variable, the maximum length being mainly defined by the weight allowed for its handling.
  • the joint cover can also be applied around chimneys which rise above the ridge and the two sides of a roof.
  • FIG. 7 schematically shows a device which may possibly be suitable for the manufacture of a joint cover, according to the invention.
  • This device comprises two rolling drums 8 and 9 with corrugated cylindrical surfaces 10 which drive in the same way as two toothed wheels and between which moves, in a substantially continuous manner, a flat strip 11 of a malleable material. The latter then undergoes between these corrugated surfaces 10 pleating or undulating.
  • the strip thus folded or corrugated is then guided between two parallel plates 13 and 14 to undergo compression therein in the longitudinal direction of the strip which is obtained by means of a controlled resistance to movement between these plates 13 and 14 by adjusting the pressure. exerted transversely by the latter, on the corrugated or pleated strip leaving the drums 8 and 9.
  • the following operation consists in cutting the pleated strips to the desired length and in subjecting them to a folding around their longitudinal axis, so as to obtain the two wings 1 and 2 forming an angle between them. ⁇ of approximately 90 °.
  • one of the wings 1 or 2 it could be sufficient for only one of the wings 1 or 2 to be pleated and, in still other cases, one or both wings may have pleated zones alternated by flat zones.
