Abstract

The flashing material consists of a strip of a malleable material, either lead or bitumen-based, folded into a series of transverse pleats (3) and then folded lengthwise to make two sides (1,2) at an angle to one another, linked by a continuous transitional zone (15). The thickness of the strip is between 0.4 and 3 mm, and the height of the pleats is between three and 10 times the thickness. One of the two sides of the folded strip is between 1.5 and 4 times the width of the other.

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 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 .

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 the junctions of a wall and a slope of the roof or around the stumps of chimneys, we apply to these places a mortar joint or noquets formed of a succession of separate portions of zinc or of 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 dimensions of these portions must generally be adapted to each particular case. In most cases, this 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, there is a risk, especially when using mortar, that after some time problems of water infiltration 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, the installation of which is very easy and effective and suitable for practically any type of joint 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.For this purpose, the joint cover, according to the invention, consists of a strip of malleable material folded around an axis parallel to its longitudinal direction at an angle (α), 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.

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 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.

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 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.

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 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.

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

D'autres détails et particularités de l'invntion ressortiront de la description donnée ci-après, à titre d'exemple non limitatif de quelques formes de réalisation particulières de l'invention.Other details and particularities of the invention will emerge from the description given below, by way of nonlimiting example of some particular embodiments of the invention.

La figure 7 est une vue schématique d'un dispositif permettant la fabrication du couvre-joint suivant l'invention.Figure 7 is a schematic view of a device for manufacturing the joint cover according to the invention.

Dans les différentes figures, les mêmes chiffres de référence concernent des éléments identiques ou analogues.In the different figures, the same reference numbers relate to identical or analogous elements.

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, 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. Such a 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 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.

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 perspective view 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 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 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, in their longitudinal direction, a succession of identical folds.

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 substantially continuous transition zone 15 between the two wings 1 and 2 according to 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 the joint cover is made, before use, 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.

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 FIG. 3, 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.

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.FIG. 4 is an illustration of a rectilinear deployment of the joint cover according to the invention, while FIG. 5 schematically shows a deployment in a curve, for example at the location of a chimney corner.

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 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.

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 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.

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 is a better seal obtained, but the working time is considerably reduced and does not in fact require any particular qualification compared to these conventional joint covers. 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 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.

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 mainly 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 faitière 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 another, the joint cover, according to the invention, can also be applied around chimneys which 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.FIG. 7 schematically shows a device which may possibly be suitable for the 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 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.

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 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.

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 FIG. 7, 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. 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 the two wings 1 and 2 to be applied more firmly against the respective surfaces extending on either 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 certain parameters of the joint cover according to the invention.

  • "l o " designates the length of the joint cover, before use, with the folds pressing against each other, as in Figure 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 and of the device for the manufacture thereof.

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.Thus, in certain cases, 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.
