Description

La présente invention est relative à un couvre-joint pour toiture, notamment pour couvrir la jonction entre une cheminée et au moins un versant d'un toit au-dessus duquel s'élève la cheminée, tel que défini dans le préambule de la revendication 1.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.

Actuellement, pour assurer l'étanchéité aux jonctions d'un mur et d'un versant de toit ou autour des souches de cheminées, on applique à ces endroits un joint de mortier ou des noquets formés d'une succession de portions séparées de zinc ou de plomb pliées en équerre et se chevauchant partiellement.Currently, to seal junctions of a wall and a roof slope or around chimney stumps, a joint is applied to these places mortar or noquets formed of a succession of separate portions of zinc or lead bent at right angles and partially overlapping.

Ces techniques connues présentent divers inconvénients non négligeables étant donné que la forme et les dimensions de ces portions doivent généralement être adaptées à chaque cas particulier. Ainsi, dans la plupart des cas, il s'agit d'un travail relativement spécialisé nécessitant souvent un temps non négligeable.These known techniques have various significant disadvantages since the shape and the dimensions of these portions should generally be adapted to each particular case. So in most of cases it is relatively specialized work often requiring significant time.

De plus, le risque existe, surtout lorsque l'on fait usage de mortier, qu'après un certain temps des problèmes d'infiltration d'eau se posent à l'endroit de la jonction.In addition, the risk exists, especially when we makes use of mortar, only after some time water infiltration problems arise at the location of the junction.

Un des buts essentiels de la présente invention est de remédier aux inconvénients précités et de proposer un couvre-joint dont la pose est très facile et efficace et convient pour pratiquement tout type de jonction au niveau de la toiture. 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.

A cet effet, le couvre-joint, suivant l'invention, est constitué d'une bande en une matière malléable pliée autour d'un axe parallèle à sa direction longitudinale suivant un angle (α), de manière à former deux ailes s'étendant côte à côte, au moins une de ces ailes présentant une succession de plis, de préférence arrondis, s'étendant suivant sa direction longitudinale sur au moins une certaine partie de sa longueur, au moins une partie de ces plis étant déformables suivant cette direction longitudinale.To this end, 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 (α), 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.

L'invention concerne également un procédé pour la mise en oeuvre de ce couvre-joint, notamment pour couvrir la jonction entre une cheminée et au moins un versant d'un toit au-dessus duquel s'élève la cheminée.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.

Ce procédé est caractérisé par le fait que l'on place le couvre-joint dans l'angle formé par la cheminée et le versant du toit en appliquant une des ailes contre la cheminée et l'autre aile contre le versant en déployant les plis de cette dernière à l'endroit des coins de la cheminée de manière à entourer ces coins.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.

Avantageusement, les deux ailes de la bande en une matière malléable présentent une succession de plis sensiblement identiques suivant leur direction longitudinale, un pli déterminé d'une des ailes s'étendant dans le prolongement d'un pli de l'autre aile.Advantageously, 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.

Avantageusement, avant l'usage, les plis successifs s'appuient sensiblement l'un contre l'autre.Advantageously, before use, the folds successive lean substantially against each other.

Suivant une forme de réalisation préférentielle de l'invention, la matière malléable précitée est à base de plomb.According to a preferred embodiment of the invention, the above malleable material is based on lead.

    L'invention concerne, d'une façon générale, un couvre-joint pour toiture, notamment pour couvrir la jonction entre une cheminée et au moins un des versants d'un toit au-dessus duquel se lève la cheminée. Un tel couvre-joint peut encore être appelé "solin".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".

    Ce couvre-joint ou solin est constitué d'une bande en une matière malléable, tel que du plomb, un produit à base de bétume ou une matière plastique appropriée, comprenant deux ailes s'étendant côte à côte en formant entr'elles un angle inférieur à 180°, de préférence de l'ordre de 90°, au moins une de ces ailes présentant une succession de plis suivant sa direction longitudinale sur au moins une partie de sa longueur, de manière à permettre une déformation de cette aile par un étirement de celle-ci en déployant partiellement ou entièrement au moins une partie de certains plis. 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.

    La figure 1 est une vue schématique en perspective d'une forme de réalisation particulière du couvre-joint 5 suivant l'invention.Figure 1 is a schematic view in perspective of a particular embodiment of the joint cover 5 according to the invention.

    Ce couvre-joint 5 est formé d'une bande continue en une matière malléable pliée en forme de L suivant son sens longitudinal de manière à obtenir ainsi deux ailes 1 et 2 s'étendant côte à côte dans la direction longitudinale 12 de cette bande et formant entr'elles un angle α de l'ordre de 90°.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 α of the order of 90 °.

    Chacune de ces ailes 1 et 2 présente, suivant leur direction longitudinale, une succession de plis identiques.Each of these wings 1 and 2 has, according to their longitudinal direction, a succession of folds identical.

    Un pli déterminé 3a d'une de ces ailes 1 et 2 s'étend dans le prolongement d'un pli 3a' de l'autre aile de manière à obtenir ainsi une zone de transition 15 sensiblement continue entre les deux ailes 1 et 2 suivant un coin arrondi.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.

    Suivant la nature de la matière malléable, dont est constitué le couvre-joint, avant usage, un léger espacement 3' peut persister entre deux plis successifs 3a et 3b, comme montré à la figure 2. La largeur de cet espacement est fonction de l'épaisseur et de la rigidité de la bande en matière malléable ainsi que de la technique appliquée pour la fabrication du couvre-joint.Depending on the nature of the malleable material, of which is made the joint cover, before use, 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.

    Dans d'autres cas, comme montré à la figure 3, les plis successifs 3a, 3b, 3c peuvent être appliqués l'un contre l'autre, avant l'usage du couvre-joint. Ceci peut présenter un certain avantage pour ce qui concerne le stockage et le transport de couvre-joints occupant ainsi un volume minimum.In other cases, as shown in Figure 3, 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.

    L'épaisseur de la bande malléable "ep" et la hauteur ou amplitude "e" des plis 3 peut être très variée, notamment en fonction de la matière utilisée et de l'emploi envisagé du couvre-joint.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.

    Ainsi, avantageusement, pour une bande en plomb, présentant une épaisseur "ep" comprise entre 0,4 et 3 mm, la hauteur "e" des plis est avantageusement comprise entre 3 et 10 fois cette épaisseur.Thus, advantageously, for a lead strip, having a thickness "e p " of between 0.4 and 3 mm, the height "e" of the folds is advantageously between 3 and 10 times this thickness.

    Il en est de même pour la largeur l1 et l2 des deux ailes 1 et 2. Pour la plupart des applications envisagées, la largeur d'au moins une des ailes de la bande en matière malléable est comprise entre 3 et 15 cm.It is the same for the width l 1 and l 2 of the two wings 1 and 2. For most of the envisaged applications, the width of at least one of the wings of the strip of malleable material is between 3 and 15 cm.

    Par ailleurs, la largeur d'une des ailes peut être comprise entre 1,5 fois et 4 fois la largeur de l'autre bande. Toutefois, pour la facilité de l'emploi, on utilise avantageusement des couvre-joints avec des ailes 1 et 2 de largeurs identiques (l1 = l2).Furthermore, the width of one of the wings can be between 1.5 times and 4 times the width of the other strip. However, for ease of use, advantageously is used joint covers with wings 1 and 2 of identical widths (l 1 = l 2 ).

    La figure 4 est une illustration d'un déployement rectiligne du couvre-joint suivant l'invention, tandis que la figure 5 montre schématiquement un déployement en courbe, par exemple à l'endroit d'un coin de cheminée.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.

    La figure 6 montre un montage du couvre-joint 5, tel que montré à la figure 1, autour d'une cheminée 6 s'élevant au-dessus du versant 7 d'un toit. Ce couvre-joint 5 est constitué d'une seule pièce continue, contrairement à ce qui est le cas pour les couvres-joints classiques connus qui sont formés d'une succession de morceaux séparés de zinc ou de plomb pliées en équerre et disposés l'un à la suite de l'autre avec un chevauchement partiel.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.

    Ainsi, suivant l'invention, l'on place le couvre-joint dans l'angle formé par la cheminée et le versant du toit en appliquant une des ailes 1 contre la cheminée et l'autre aile 2 contre le versant en déployant les plis 3 de cette dernière à l'endroit des coins de la cheminée de manière à entourer ces coins.Thus, according to the invention, 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.

    De cette façon, non seulement une meilleure étanchéité est obtenue, mais le temps de travail est considérablement réduit et ne nécessite en fait aucune qualification particulière comparé à ces couvre-joints classiques. Les couvre-joints, suivant l'invention, peuvent ainsi être coupés à la longueur voulue. In this way, not only better tightness is obtained, but the working time is significantly reduced and in fact requires no special qualification compared to these joint covers classics. The joint covers according to the invention, can thus be cut to the desired length.

    Avantageusement, les couvre-joints présentent à chacune de leurs extrémités une zone non-plissée 16 permettant ainsi le chevauchement de deux couvre-joints successifs dans le cas du recouvrement de jonctions relativement longues.Advantageously, 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.

    En principe, la longueur d'un couvre-joint peut être très variable, la longueur maximale étant surtout définie par le poids admis pour sa manipulation.In principle, the length of a joint cover can be very variable, the maximum length being above all defined by the weight allowed for its handling.

    Par le fait que chacune des deux ailes 1 et 2 peut être déployée en courbe, indépendamment l'une de l'autre, le couvre-joint, suivant l'invention, peut être appliqué également autour de cheminées qui s'élèvent au-dessus de la faítière et des deux versants d'un toit.By the fact that 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.

    La figure 7 montre schématiquement un dispositif pouvant éventuellement convenir pour la fabrication d'un couvre-joint, suivant l'invention.Figure 7 schematically shows a device which may be suitable for manufacture of a joint cover according to the invention.

    Ce dispositif comprend deux tambours de laminage 8 et 9 à surfaces cylindriques ondulées 10 qui s'engrainent de la même façon que deux roues dentées et entre lesquelles se déplace, d'une manière sensiblement continue, une bande plane 11 en une matière malléable. Cette dernière subit alors entre ces surfaces ondulées 10 un plissage ou ondulation.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.

    La bande ainsi plissée ou ondulée est ensuite guidée entre deux plaques parallèles 13 et 14 pour y subir une compression dans le sens longitudinal de la bande qui est obtenue grâce à une résistance contrôlée au déplacement entre ces plaques 13 et 14 par un réglage de la pression exercée transversalement par ces dernières, sur la bande ondulée ou plissée sortant des tambours 8 et 9.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.

    L'opération suivante, non représentée à la figure 7, consiste à couper les bandes plissées à longueur voulue et à les soumettre à un pliage autour de leur axe longitudinal, de manière à obtenir les deux ailes 1 et 2 formant entr'elles un angle α d'environ 90°.The following operation, not shown in the figure 7, 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 α of approximately 90 °.

    Dans la pratique, il pourrait être utile de former un angle α légèrement supérieur à 90°, de manière à permettre d'appliquer plus fermement les deux ailes 1 et 2 contre les surfaces respectives s'étendant de part et d'autre de la jonction à recouvrir et formant entr'elles un angle sensiblement droit.In practice, it might be useful to form an angle α slightly greater than 90 °, so that allow to apply more firmly the two wings 1 and 2 against the respective surfaces extending on either side and other side of the junction to be covered and forming between them a substantially right angle.

    Ci-après sont donnés, à titre illustratif, deux exemples concrets de certains paramètres du couvre-joint suivant l'invention.Below are given, by way of illustration, two concrete examples of some parameters of the joint cover according to the invention.

    Exemple 1Example 1

    ep = 0,65 mme p = 0.65 mm e = 3 mme = 3 mm a = 18 mma = 18 mm n = 327n = 327 ld = 2 X 19 + 2 X 327 X 3 = 2000 mml d = 2 X 19 + 2 X 327 X 3 = 2000 mm lo = 463,1 mml o = 463.1 mm

    Exemple 2Example 2

    ep = 0,65 mme p = 0.65 mm e = 6 mme = 6 mm a = 22 mma = 22 mm n = 163n = 163 ld = 2 X 22 + 2 X 163 X 6 = 2000 mml d = 2 X 22 + 2 X 163 X 6 = 2000 mm lo = 255,9 mml o = 255.9 mm

    Dans ces deux exemples :

  • "lo" désigne la longueur du couvre-joint, avant usage, avec les plis s'appuyant l'un contre l'autre, comme dans la figure 3;
  • "ld" désigne la longueur du couvre-joint entièrement déployé, ou encore de la bande en matière malléable à l'état plan avant l'opération de plissage ;
  • "a" désigne la largeur des deux bords d'extrémité non plissés du couvre-joint;
  • "e" désigne l'amplitude ou la hauteur des plis;
  • "ep" désigne l'épaisseur de la bande en matière malléable;
  • "n" désigne le nombre total de plis d'un couvre-joint.
    • In these two examples:
  • "l o " designates the length of the joint cover, before use, with the folds pressing against each other, as in FIG. 3;
  • "l d " designates the length of the fully deployed joint cover, or of the strip of malleable material in the planar state before the pleating operation;
  • "a" designates the width of the two non-pleated end edges of the joint cover;
  • "e" designates the amplitude or the height of the folds;
  • "e p " denotes the thickness of the strip of malleable material;
  • "n" indicates the total number of folds of a joint cover.

    • Il est bien entendu que l'invention n'est pas limitée à la forme de réalisation décrite ci-dessus du couvre-joint suivant l'invention ainsi que du dispositif pour la fabrication de celui-ci. It is understood that the invention is not limited to the embodiment described above of the joint cover according to the invention as well as the device for making it.

    Ainsi, dans certains cas, il pourrait suffire que seulement une des ailes 1 ou 2 soit plissée et, dans d'autres cas encore, une ou les deux ailes peut présenter des zones plissées alternées par des zones planes.So in some cases it might be enough that only one of wings 1 or 2 is folded and, in in other cases, one or both wings may present pleated areas alternated by flat areas.
