Definitions

  • the present invention relates to a joint cover for roofing, in particular for covering the joint between a chimney and at least one slope of a roof above from which rises the chimney, 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 whose installation is very easy and effective and suitable for almost any type of connection at the level of the roof.
  • the following joint cover the invention consists of a strip of material malleable folded around an axis parallel to its direction longitudinal at an angle ( ⁇ ), so as to form two wings extending side by side, at least one of these wings with a succession of folds, preferably rounded, extending in its longitudinal direction over at least a certain part of its length, at least one part of these folds being deformable according to this longitudinal direction.
  • the invention also relates to a method for the implementation of this joint cover, in particular for cover 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 place the joint cover 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 in a malleable material have a succession of folds substantially identical in their direction longitudinal, a determined fold of one of the wings extending in the extension of a fold of the other wing.
  • the above malleable material is based on lead.
  • the invention relates generally to a roofing joint covering, in particular for covering the junction between a chimney and at least one of the slopes a roof above which the chimney rises.
  • Such joint cover can also be called "flashing".
  • This joint cover or flashing consists of a strip of malleable material such as lead, product based on betume or a plastic material suitable, comprising two wings extending side by side in forming between them an angle of less than 180 °, preferably of the order of 90 °, at least one of these wings having a succession of folds in its longitudinal direction on at least part of its length, so as to allow a deformation of this wing by a stretching thereof by partially or fully deploying at least one part of some folds.
  • a strip of malleable material such as lead, product based on betume or a plastic material suitable
  • Figure 1 is a schematic view in perspective of a particular embodiment of the joint cover 5 according to the invention.
  • This joint cover 5 is formed by a strip continuous in a malleable material folded in an L shape in its longitudinal direction so as to obtain two wings 1 and 2 extending side by side in the direction longitudinal 12 of this strip and forming between them a angle ⁇ of the order of 90 °.
  • Each of these wings 1 and 2 has, according to their longitudinal direction, a succession of folds identical.
  • 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 transition zone 15 substantially continuous between the two wings 1 and 2 following a rounded corner.
  • a slight spacing 3 'can persist between two successive folds 3a and 3b, as shown in Figure 2.
  • the width of this spacing is a function of the thickness and stiffness of the strip of malleable material as well as of the technique applied for the manufacture of the joint cover.
  • successive folds 3a, 3b, 3c can be applied one against each other, before using the joint cover. This can have some advantage with regard to 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 ).
  • Figure 4 is an illustration of a rectilinear deployment of the joint cover according to the invention, while Figure 5 schematically shows a roll-out, for example at the corner of a fireplace.
  • 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 the case for joint covers known classics that are formed of a succession of separate pieces of zinc or lead bent at right angles and arranged one after the other with an overlap part.
  • the joint cover in the angle formed by the chimney and the slope of the roof by applying one of the wings 1 against the chimney and the other wing 2 against the slope by deploying folds 3 of the latter at the corners 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 each of their ends a non-pleated zone 16 thus allowing the overlap of two joint covers successive in the case of overlapping junctions relatively long.
  • the length of a joint cover can be very variable, the maximum length being above all defined by the weight allowed for its handling.
  • each of the two wings 1 and 2 can be deployed in a curve, independently of one of the other, the joint cover, according to the invention, can be also applied around chimneys that rise above the ridge and the two sides of a roof.
  • Figure 7 schematically shows a device which may be suitable for manufacture of a joint cover according to the invention.
  • This device includes two drums rolling 8 and 9 with corrugated cylindrical surfaces 10 which behave in the same way as two cogwheels and between which moves, in a substantially continuous, a flat strip 11 of a malleable material. The latter then undergoes between these corrugated surfaces 10 pleating or waving.
  • the pleated or corrugated strip is then guided between two parallel plates 13 and 14 to undergo a compression in the longitudinal direction of the band which is obtained thanks to a controlled resistance to displacement between these plates 13 and 14 by adjusting the pressure exerted transversely by the latter, on the strip wavy or pleated coming out of drums 8 and 9.
  • the following operation consists of cutting the pleated strips to length and fold them around their axis longitudinal, so as to obtain the two wings 1 and 2 forming between them an angle ⁇ of approximately 90 °.
  • wings 1 or 2 may present pleated areas alternated by flat areas.
