  • the invention relates to an insulating support for receiving a sub-tile plate and may also have a decorative face.
  • Under-tile plates are building elements generally placed between the roof and the roof structure. They can be rigid or flexible. When rigid, they can be used directly as a roof element. However, in the majority of cases, the sub-tile plates support a roof covering such as tiles, especially channel tiles.
  • the role of the underlay tiles is to collect and remove the water present under the roof covering due to infiltration due to weather or other or due to condensation to protect the insulation.
  • the sub-tile plates may be flat or consist of a plurality of depressions (cx) and ridges (C) so as to describe a regular and repetitive sinusoid pattern.
  • the under-tile plates are arranged on the roof overlapping to ensure watertightness.
  • the lateral overlap corresponds to a half-sinusoid and the longitudinal overlap takes place about twenty centimeters.
  • the corrugated under-tile plates can be used in particular to support hollow tiles called channel tiles. These tiles can be arranged on the plates so as to form a succession of alternating rows of current tiles placed on the hollows (cx) of the plate and roof tiles placed on the crests (C) of the plate (cover 2 tiles ).
  • the sub-tile plates allow an alternative in the tile layout by saving the number of tiles per m 2 . Indeed, it is possible to remove the current tiles placed in the hollows (cx) of the plate, the waterproofness of the roof being ensured then only by the sub-tile plates and not by the tiles themselves (cover 1 tile ).
  • the sub-tile plates can be placed on battens themselves arranged on the frame.

However, in the majority of cases, the sub-tile plates support a roof covering such as tiles, especially channel tiles.

Le rôle des plaques sous-tuiles est de récolter et d'évacuer l'eau présente sous la couverture du toit en raison d'infiltrations dues aux intempéries ou autres ou bien en raison de la condensation afin de protéger l'isolation.The role of the underlay tiles is to collect and remove the water present under the roof covering due to infiltration due to weather or other or due to condensation to protect the insulation.

Les plaques sous-tuiles peuvent être planes ou être constituées d'une pluralité de creux (cx) et de crêtes (C) de façon à décrire un motif en forme de sinusoïde régulier et répétitif.The sub-tile plates may be flat or consist of a plurality of depressions (cx) and ridges (C) so as to describe a regular and repetitive sinusoid pattern.

Pour leur mise en place, les plaques sous-tuiles sont disposées sur le toit en se chevauchant pour assurer l'étanchéité. De façon usuelle, le chevauchement latéral correspond à une demi-sinusoïde et le chevauchement longitudinal s'effectue sur une vingtaine de centimètres.For their placement, the under-tile plates are arranged on the roof overlapping to ensure watertightness. Usually, the lateral overlap corresponds to a half-sinusoid and the longitudinal overlap takes place about twenty centimeters.

Les plaques sous-tuiles de type ondulé peuvent servir en particulier à supporter des tuiles creuses appelées tuiles canal. Ces tuiles peuvent être disposées sur les plaques de façon à former une succession de rangées alternées de tuiles de courant posées sur les creux (cx) de la plaque et de tuiles de couvert posées sur les crêtes (C) de la plaque (couverture 2 tuiles).The corrugated under-tile plates can be used in particular to support hollow tiles called channel tiles. These tiles can be arranged on the plates so as to form a succession of alternating rows of current tiles placed on the hollows (cx) of the plate and roof tiles placed on the crests (C) of the plate (cover 2 tiles ).

Cependant, les plaques sous-tuiles permettent une alternative dans la disposition de tuiles en économisant le nombre de tuiles au m2. En effet, il est possible de supprimer les tuiles de courant posées dans les creux (cx) de la plaque, l'étanchéité du toit étant assurée alors uniquement par les plaques sous-tuiles et non par les tuiles elles-mêmes (couverture 1 tuile).However, the sub-tile plates allow an alternative in the tile layout by saving the number of tiles per m 2 . Indeed, it is possible to remove the current tiles placed in the hollows (cx) of the plate, the waterproofness of the roof being ensured then only by the sub-tile plates and not by the tiles themselves (cover 1 tile ).

De ce fait il existe des plaques sous-tuiles dont le profil sinusoïdal est différent selon le sens d'orientation de ladite plaque cela pour permettre la pose en couverture 1 tuile ou en couverture 2 tuiles.As a result, there are sub-tile plates whose sinusoidal profile is different depending on the direction of orientation of said plate to allow the laying of cover 1 tile or cover 2 tiles.

Les plaques sous-tuiles peuvent être posées sur des liteaux eux-mêmes disposés sur la charpente. Cependant les normes actuelles imposent une isolation entre la couverture et l'intérieur de l'édifice porteur de la toiture. A cet égard de nombreux moyens d'isolation sont connus mais en général ils nécessitent des modalités de poses délicates et consommatrices de temps. De plus il faut envisager d'ajouter à l'isolation un moyen décoratif assurant une finition correcte en sous toiture.The sub-tile plates can be placed on battens themselves arranged on the frame. However, current standards impose insulation between the roof and the interior of the building carrying the roof. In this respect, many insulation means are known but in general they require delicate and time consuming poses. In addition it is necessary to consider adding to the insulation a decorative means ensuring a correct finish under the roof.

L'invention vise à simplifier la pose de toiture en tuile canal comportant une plaque sous-tuiles en fournissant un support isolant pour la réalisation de couverture de bâtiment, destiné à recevoir sur sa face supérieure une plaque sous-tuiles, ledit support comprenant de l'extérieur vers l'intérieur une couche d'isolant et éventuellement sur la face inférieure de ladite couche d'isolant un panneau décoratif.The invention aims at simplifying the laying of roof tile channel comprising a sub-tile plate by providing an insulating support for the realization of building cover, intended to receive on its upper face a plate under-tiles, said support comprising an outer layer of insulation and optionally on the underside of said insulation layer a decorative panel.

Ainsi l'invention a pour objet un support isolant de plaque sous-tuiles pour la réalisation de couverture de bâtiment, destiné à recevoir sur sa face supérieure une plaque sous-tuiles, ledit support étant de forme globalement parallélépipédique rectangle comprenant 1 face supérieure, 1 face inférieure, 2 faces latérales, une face aval, une face amont, caractérisé en ce que ladite face supérieure peut présenter une pluralité de crêtes (C) parallèles et orientées selon le grand axe dudit support, et des zones inter-crêtes ou creux (cx), lesdites zones inter-crêtes ou creux (cx) étant délimités latéralement par lesdites crêtes (C) et en ce que

  • les plans de ladite face supérieure (21, 31, 41, 51, 71) et de ladite face inférieure (22, 32, 42, 52) ne sont pas parallèles longitudinalement, induisant ainsi entre la face amont (25, 45, 65, 75) et la face aval (24, 34, 44, 54, 64, 74) une différence de hauteur dans le sens longitudinal créant ainsi une pente de ladite face supérieure dans le sens longitudinal ; ou
  • les plans formés par le fond des creux (cx) et le plan de ladite face inférieure (22, 32, 42, 52) ne sont pas parallèles longitudinalement induisant ainsi entre la face amont (25, 45, 65, 75) et la face aval (24, 34, 44, 54, 64, 74) une différence de hauteur sur les faces aval et amont, entre le fond d'un creux et la face inférieure créant ainsi une pente dudit fond du creux (cx) dans le sens longitudinal.
Thus, the subject of the invention is an insulating plate support under tiles for producing a building roof, intended to receive on its upper face a sub-tile plate, said support being of generally rectangular parallelepipedal shape comprising 1 upper face, 1 lower face, two lateral faces, a downstream face, an upstream face, characterized in that said upper face may have a plurality of ridges (C) parallel and oriented along the major axis of said support, and intercrest or hollow zones ( cx), said intercrest or hollow zones (cx) being delimited laterally by said ridges (C) and in that
  • the planes of said upper face (21, 31, 41, 51, 71) and said lower face (22, 32, 42, 52) are not parallel longitudinally, thus inducing between the upstream face (25, 45, 65, 75) and the downstream face (24, 34, 44, 54, 64, 74) a height difference in the longitudinal direction thereby creating a slope of said upper face in the longitudinal direction; or
  • the planes formed by the bottom of the recesses (cx) and the plane of the said lower face (22, 32, 42, 52) are not parallel longitudinally thus inducing between the upstream face (25, 45, 65, 75) and the face downstream (24, 34, 44, 54, 64, 74) a difference in height on the downstream and upstream faces, between the bottom of a hollow and the lower face thus creating a slope of said bottom of the hollow (cx) in the longitudinal direction.

Par "faces latérales" on entend ici les 2 faces présentes de chaque côté du grand axe longitudinal dudit support selon l'invention, et par "face amont" et "face aval" les faces présentes de chaque côté de l'axe transversal dudit support."Side faces" here means the two faces present on each side of the major longitudinal axis of said support according to the invention, and "upstream face" and "downstream face" the faces present on each side of the transverse axis of said support .

As previously stated
  • according to a first particular embodiment of the invention the plane of said upper face, therefore the plane encompassing the peaks of the peaks, and the plane of said lower face of said support may be parallel longitudinally, thereby ensuring that it there is no slope (p) of the upper face with respect to the lower face and that there is no difference in height (h) between the upstream face and the downstream face of said support, and the plane encompassing the bottom of the recesses may be parallel to the plane of the lower face. It is thus understood that according to this particular embodiment of the invention the support according to the invention may have no slope in the longitudinal direction relative to the lower face of either its upper face and the plane encompassing the bottom of the hollows . This embodiment also has the advantage of facilitating the storage of said supports which can be stacked without worry of catching slope.
  • according to a second particular embodiment of the invention the plane of said upper face, therefore the plane encompassing the peaks of the peaks, and the plane of said lower face of said support, may not be parallel longitudinally, thus inducing a slope (p ) of the upper face with respect to the lower face and a difference in height (h) between the upstream face and the downstream face and the plane including the bottom of the recesses may be parallel to the plane of the lower face.

This embodiment also has the advantage of facilitating the storage of said supports which can be stacked without worry of catching slope.

Quelle que soit la forme de réalisation retenue, la présence d'une pente (p) en face supérieure a pour conséquence que les faces amont et aval sont de hauteurs différentes soit sur toute leur surface soit seulement au niveau du fond des creux (h).Whatever the embodiment chosen, the presence of a slope (p) in the upper face has the consequence that the upstream and downstream faces are of different heights either over their entire surface or only at the bottom of the hollows (h) .

Selon une forme de réalisation de l'invention la hauteur (h) de la face amont ou la hauteur (h) entre la face inférieure et le fond des creux (h, Figure 3) en face amont pourra être inférieure à la hauteur de la face aval ou entre la face inférieure et le fond des creux (h, Figure 3) en face aval. Amont et aval étant définis par référence au sens de pose dudit support par rapport à la pente de la toiture à recouvrir, on comprend alors que ladite pente (p) soit de la surface supérieure dudit support, soit à tout le moins du fond desdits creux portés par ladite face supérieure est à contrepente de la pente de la toiture à réaliser. Il s'agit là d'une forme préférée de l'invention.According to one embodiment of the invention the height (h) of the upstream face or the height (h) between the lower face and the bottom of the hollows (h, Figure 3 ) on the upstream face may be less than the height of the downstream face or between the lower face and the bottom of the depressions (h, Figure 3 ) on the downstream face. Upstream and downstream being defined by reference to the laying direction of said support relative to the slope of the roof to be covered, it is understood that said slope (p) is the upper surface of said support, or at least the bottom of said hollow carried by said upper face is against the slope of the roof to achieve. This is a preferred form of the invention.

Selon cette forme de réalisation de l'invention, la présence d'une pente (p) en face supérieure, à tout le moins au fond desdits creux portés par ladite face supérieure, a pour conséquence que ledit support présente un sens défini par ladite pente (p) et que lors de sa pose ledit support devra être positionné d'une manière particulière qui voudra que la pente (p) de la face supérieure ou la pente (p) du fond des creux soit à contre-pente de la pente de la couverture en cours de réalisation.According to this embodiment of the invention, the presence of a slope (p) in the upper face, at least at the bottom of said recesses borne by said upper face, has the consequence that said support has a direction defined by said slope. (p) and that during its installation said support will have to be positioned in a particular way which will want that the slope (p) of the upper face or the slope (p) of the bottom of the hollows is at the opposite slope of the slope of the coverage in progress.

Cela impose donc que la face de plus petite hauteur, c'est-à-dire correspondant au bas de la pente (p) de la face supérieure ou de la pente (p) du fond des creux, soit positionnée vers le haut de la couverture en cours de réalisation ; elle correspondra alors à la face dite amont. De même cela impose donc que la face de plus grande hauteur, c'est-à-dire correspondant au haut de la pente (p) de la face supérieure ou de la pente (p) du fond des creux, soit positionnée vers le bas de la couverture en cours de réalisation ; elle correspondra alors à la face dite aval.This therefore requires that the face of smaller height, that is to say corresponding to the bottom of the slope (p) of the upper face or the slope (p) of the bottom of the hollows, is positioned towards the top of the coverage in progress; it will then correspond to the so-called upstream face. Similarly, it therefore requires that the face of greater height, that is to say corresponding to the top of the slope (p) of the upper face or the slope (p) of the bottom of the hollows, is positioned downwards. coverage in progress; it will then correspond to the so-called downstream face.

Selon une autre forme de réalisation de l'invention la hauteur (h) de la face amont ou la hauteur (h) entre la face inférieure et le fond des creux (h, Figure 3) en face amont pourra être supérieure à la hauteur de la face aval ou entre la face inférieure et le fond des creux (h, Figure 3) en face aval. Amont et aval étant définis par référence au sens de pose dudit support par rapport à la pente de la toiture à recouvrir, on comprend alors que ladite pente (p) soit de la surface supérieure dudit support, soit à tout le moins du fond desdits creux portés par ladite face supérieure est dans le sens de la pente de la toiture à réaliser.According to another embodiment of the invention the height (h) of the upstream face or the height (h) between the lower face and the bottom of the hollows (h, Figure 3 ) on the upstream face may be greater than the height of the downstream face or between the face lower and the bottom of the hollows (h, Figure 3 ) on the downstream face. Upstream and downstream being defined by reference to the laying direction of said support relative to the slope of the roof to be covered, it is understood that said slope (p) is the upper surface of said support, or at least the bottom of said hollow carried by said upper face is in the direction of the slope of the roof to achieve.

L'invention présente entre autres les avantages suivants : pose et fixation de la plaque sous-tuiles et du support isolant selon l'invention en une seule opération, ledit support isolant selon l'invention est léger et facile à manipuler, il est unique que l'on réalise une couverture à 1 tuile ou à 2 tuiles, les caractéristiques géométriques dudit support selon l'invention impose un sens de pose qui facilite celle-ci, ledit support permet en outre de n'utiliser qu'une fixation pour l'ensemble plaque sous-tuiles/support isolant.The invention has among others the following advantages: laying and fixing the sub-tile plate and the insulating support according to the invention in a single operation, said insulating support according to the invention is light and easy to handle, it is unique that a cover is made to 1 tile or 2 tiles, the geometric characteristics of said support according to the invention imposes a direction of installation which facilitates it, said support also allows to use only a fixation for the Under-tile plate / insulating support.

Selon l'invention, ledit support isolant peut être en toute matière connue pour permettre une isolation thermique et/ou phonique pour peu qu'elle soit compatible avec la fonction de l'invention. Ainsi selon l'invention ladite matière isolante peut être choisie parmi le chanvre, particulièrement sous forme de brique, la fibre de bois sous forme rigide, comme par exemple le fibragglo, le liège expansé, ou encore à base de polymères, de mousses de polymère comme par exemple la mousse d'urée-formaldéhyde, la mousse phénolique, la mousse de polychlorure de vinyle, la mousse de polyuréthane, le polystyrène extrudé, le polystyrène expansé qu'il soit graphité ou non, le polyisocyanurate. Avantageusement selon l'invention l'isolant est du polystyrène extrudé ou du polystyrène expansé, préférentiellement du polystyrène graphité.According to the invention, said insulating support may be of any known material to allow thermal insulation and / or sound if it is compatible with the function of the invention. Thus according to the invention, said insulating material may be chosen from hemp, particularly in the form of brick, wood fiber in rigid form, such as, for example, fibragglo, expanded cork, or based on polymers or polymer foams. such as, for example, urea-formaldehyde foam, phenolic foam, polyvinyl chloride foam, polyurethane foam, extruded polystyrene, expanded polystyrene, whether or not graphitized, polyisocyanurate. Advantageously according to the invention the insulator is extruded polystyrene or expanded polystyrene, preferably polystyrene graphite.

Selon l'invention, les faces inférieure et supérieure dudit support, de forme globalement rectangulaire, peuvent avoir une longueur comprise entre 0,50 m et 4,00 m, préférentiellement entre 0,80 m et 3,50 m, très préférentiellement entre 0,90 m et 2,00 m.According to the invention, the lower and upper faces of said support, of generally rectangular shape, may have a length of between 0.50 m and 4.00 m, preferably between 0.80 m and 3.50 m, very preferably between 0 , 90 m and 2.00 m.

Selon l'invention, les faces inférieure et supérieure dudit support, de forme rectangulaire, peuvent avoir une largeur comprise entre 0,50 m et 2,50 m, préférentiellement entre 0,80 m et 2,00 m, très préférentiellement entre 0,90 m et 1,20 m.According to the invention, the lower and upper faces of said support, of rectangular shape, may have a width of between 0.50 m and 2.50 m, preferably between 0.80 m and 2.00 m, very preferably between 0, 90 m and 1.20 m.

Selon l'invention quelle que soit la forme de réalisation de l'invention, les faces amont et aval dudit support pourront avoir une hauteur globale comprise entre 0,10 m et 0,30 m, préférentiellement entre 0,15 m et 0,27m.According to the invention, whatever the embodiment of the invention, the upstream and downstream faces of said support may have an overall height of between 0.10 m and 0.30 m, preferably between 0.15 m and 0.27 m. .

Par hauteur globale on comprend qu'il s'agit de la distance entre le sommet des crêtes (C) portée par la face supérieure dudit support et la face inférieure dudit support.By overall height it is understood that it is the distance between the summit of the ridges (C) carried by the upper face of said support and the underside of said support.

Bien entendu les faces amont et aval dudit support auront une largeur identique entre elles et identique à la largeur desdites faces inférieure et supérieure.Of course the upstream and downstream faces of said support will have an identical width between them and identical to the width of said lower and upper faces.

Selon la forme de réalisation dans laquelle ledit support peut présenter une face supérieure en pente dans le sens longitudinal par rapport à la face inférieure lesdites faces amont et aval pourront avoir des hauteurs globales différentes.According to the embodiment in which said support may have an upper face slope in the longitudinal direction relative to the lower face said upstream and downstream faces may have different overall heights.

Selon la forme de réalisation dans laquelle seul le fond des creux dudit support peut présenter une pente dans le sens longitudinal par rapport à la face inférieure on comprend que globalement les faces amont et aval pourront avoir des hauteurs identiques, et que seules la hauteur (h), sur les faces aval et amont, entre le fond d'un creux et la face inférieure pourront être différentes.According to the embodiment in which only the bottom of the recesses of said support may have a slope in the longitudinal direction relative to the lower face it is understood that overall the upstream and downstream faces may have identical heights, and that only the height (h ), on the downstream and upstream faces, between the bottom of a hollow and the lower face may be different.

Quelle que soit la forme de réalisation de l'invention, ladite pente (p) peut être comprise entre 0,1% et 1,0%, préférentiellement entre 0,2% et 0,80% très préférentiellement entre 0,3 et 0,5%.Whatever the embodiment of the invention, said slope (p) may be between 0.1% and 1.0%, preferably between 0.2% and 0.80%, very preferably between 0.3 and 0%. , 5%.

L'homme du métier saura sans difficulté sur la base de la longueur (L) du support selon l'invention, de la hauteur (h) de la face amont et de la pente (p) qu'il décidera de donner audit support, déterminer sans difficulté la différence de hauteur (y) entre la face aval et la face amont (deuxième et quatrième forme de réalisation ci-dessus) ou entre la hauteur (h) définie entre la face inférieure et le fond des creux en face amont et la hauteur (h) définie entre la face inférieure et le fond des creux en face aval (troisième et quatrième forme de réalisation ci-dessus) selon la formule (y) = L x p/100 (p étant exprimé en %).The person skilled in the art will know without difficulty on the basis of the length (L) of the support according to the invention, the height (h) of the upstream face and the slope (p) that he decides to give to said support, to determine without difficulty the difference in height (y) between the downstream face and the upstream face (second and fourth embodiment above) or between the height (h) defined between the lower face and the bottom of the upstream faces and the height (h) defined between the lower face and the bottom of the downstream face recesses (third and fourth embodiment above) according to the formula (y) = L xp / 100 (p being expressed in%).

Selon une forme particulière de réalisation, le support selon l'invention peut comprendre en outre sur sa face supérieure, à la jonction avec la face aval, sur toute sa largeur ou seulement au droit des creux (cx), un ou plusieurs évidement(s) (E) de forme rectangulaire et de profondeur constante, ladite profondeur pouvant correspondre à la différence de hauteur (y) de la face aval et de la face amont ou à la différence de hauteur des seules zones (Z) des faces amont et aval au droit des creux (cx).According to a particular embodiment, the support according to the invention may further comprise on its upper face, at the junction with the downstream face, over its entire width or just to the right of the recesses (cx), one or more recess (s). ) (E) of rectangular shape and constant depth, said depth being able to correspond to the height difference (y) of the downstream face and the upstream face or the difference in height of the only zones (Z) of the upstream and downstream faces to the right of the hollows (cx).

Ainsi selon l'invention ledit évidement peut avoir une profondeur constante comprise entre 1 et 15 mm, préférentiellement entre 5 et 10 mm.Thus according to the invention said recess may have a constant depth of between 1 and 15 mm, preferably between 5 and 10 mm.

Lors du montage lorsque l'on accole deux supports selon l'invention par juxtaposition de leurs faces amont et aval et que l'on pose une plaque sous-tuiles sur chaque support, ladite pente vise à permettre un recouvrement "automatique" de 2 plaques sous-tuiles, posées sur 2 supports contigus. Par principe pour assurer l'étanchéité par recouvrement de 2 plaques sous-tuiles contiguës lesdites plaques sous-tuiles pourront déborder dudit support tant du côté amont que du côté aval. Ainsi, la plaque sous-tuiles posée sur le support aval, viendra reposer par sa partie amont qui dépasse du support aval sur l'évidement ménagé dans le support amont, la plaque sous-tuiles posée sur le support amont venant reposer par sa partie aval qui dépasse du support amont sur la plaque sous-tuile aval, ménageant ainsi un recouvrement automatique des 2 plaques sous-tuiles assurant l'étanchéité de la toiture.During assembly when two supports according to the invention are joined by juxtaposition of their upstream and downstream faces and that a sub-tile plate is placed on each support, said slope is intended to allow an "automatic" overlap of 2 plates under-tiles, laid on 2 contiguous supports. In principle, to ensure the overlapping sealing of two contiguous sub-tile plates, said sub-tile plates may protrude from said support both on the upstream side and on the downstream side. Thus, the sub-tile plate placed on the downstream support, will come to rest by its upstream portion which protrudes from the downstream support on the recess formed in the upstream support, the sub-tile plate placed on the upstream support coming to rest by its downstream part. which protrudes from the upstream support on the downstream sub-tile plate, thus providing an automatic overlap of the two sub-tile plates ensuring the tightness of the roof.

Préférentiellement selon l'invention, ladite face supérieure pourra comprendre autant de crêtes (C) que la face inférieure des plaques sous-tuiles qu'elle est destinée à recevoir comportera elle-même de crêtes (C).Preferably, according to the invention, said upper face may comprise as many ridges (C) as the lower face of the sub-tile plates that it is intended to receive itself will comprise ridges (C).

Selon ce mode de réalisation particulier ladite face supérieure dudit support selon l'invention pourra comporter 4 ou 5 crêtes (C).According to this particular embodiment, said upper face of said support according to the invention may comprise 4 or 5 peaks (C).

Lesdites crêtes (C) peuvent être de longueurs variées allant de quelques centimètres de longueur à une taille identique à la longueur dudit support. Préférentiellement selon l'invention lesdites crêtes (C) pourront avoir une longueur identique à la longueur dudit support.Said ridges (C) may be of various lengths ranging from a few centimeters in length to a size identical to the length of said support. Preferably, according to the invention, said peaks (C) may have a length identical to the length of said support.

Selon un mode de réalisation de l'invention lesdites crêtes (C) pourront être à égales distance les unes des autres délimitant ainsi des creux (cx) de même largeur. Dans cette forme de réalisation, la distance entre le sommet de 2 crêtes (C) contiguës pourra être identique à la distance entre 2 points médians de 2 creux (cx) contigus.According to one embodiment of the invention, said peaks (C) may be at equal distances from each other and thus delimit recesses (cx) of the same width. In this embodiment, the distance between the vertex of 2 contiguous peaks (C) may be identical to the distance between 2 midpoints of 2 adjacent hollows (cx).

Selon leur disposition sur la surface on comprend que les crêtes (C) peuvent délimiter entre elles n-1, n ou n+1 creux.According to their arrangement on the surface it is understood that the ridges (C) may delimit between them n-1, n or n + 1 hollow.

Selon une forme de réalisation particulière une crête pourra être disposée le long de l'un des bords dudit support de l'invention, l'autre bord dudit support pouvant recevoir un creux, l'ensemble des crêtes (C) délimitant ainsi un nombre n de creux (cx) égal au nombre de crêtes (C).According to a particular embodiment a ridge may be arranged along one of the edges of said support of the invention, the other edge of said support being able to receive a recess, the set of peaks (C) thus delimiting a number n of hollow (cx) equal to the number of peaks (C).

Selon une autre forme de réalisation particulière, une demi-crête pourra être positionnée le long de chacun des 2 bords latéraux dudit support de l'invention. Selon cette forme particulière de l'invention, par ailleurs forme préférée, ledit support pourra compter n creux (cx), n-1 crêtes (C) complètes et 2 demi-crêtes.According to another particular embodiment, a half-crest may be positioned along each of the two lateral edges of said support of the invention. According to this particular form of the invention, moreover preferred form, said support can count n recesses (cx), n-1 peaks (C) complete and 2 half-peaks.

Selon encore une autre forme de réalisation particulière, un demi-creux (cx) pourra être positionné le long de chacun des 2 bords latéraux dudit support de l'invention. Selon cette forme particulière de l'invention ledit support pourra compter n crêtes (C), n-1 creux (cx) et 2 demi-demi-creux.According to yet another particular embodiment, a half-hollow (cx) may be positioned along each of the two lateral edges of said support of the invention. According to this particular form of the invention said support can count n peaks (C), n-1 hollow (cx) and 2 half-half-hollow.

Lesdits creux (cx) et crêtes (C) ont pour objet de permettre, au cours de la réalisation de la toiture, un positionnement aisé et immédiat de la plaque sous-tuiles devant reposer sur ledit support selon l'invention.Said hollows (cx) and crests (C) are intended to allow, during the realization of the roof, an easy and immediate positioning of the sub-tile plate to rest on said support according to the invention.

Selon une forme de réalisation de l'invention, la hauteur entre le sommet d'une crête (C) et le fond d'un creux (cx) présents sur ledit support selon l'invention pourra être inférieure à la hauteur entre le sommet d'une crête (α ou γ) et le fond d'un creux (δ ou β) présents sur ladite plaque sous-tuile. Avec cette forme de réalisation de l'invention, lors de la pose les plaques sous-tuile viendront prendre appui sur le support selon l'invention par mise en contact du sommet des crêtes présentes à la face inférieure de ladite plaque sous-tuile (α ou γ) et le fond des creux (cx) dudit support selon l'invention. Ainsi il subsistera un espace libre favorisant la circulation de l'air entre le sommet des crêtes (C) présentes à la surface du support selon l'invention et la plaque sous-tuile. Cette forme de réalisation dudit support selon l'invention est la forme préférée de l'invention.According to one embodiment of the invention, the height between the vertex of a peak (C) and the bottom of a hollow (cx) present on said support according to the invention may be less than the height between the peak of a peak (α or γ) and the bottom of a hollow (δ or β) present on said sub-tile plate. With this embodiment of the invention, during laying the sub-tile plates will be supported on the support according to the invention by contacting the top of the ridges present at the underside of said sub-tile plate (α or γ) and the bottom of the recesses (cx) of said support according to the invention. Thus there will remain a free space promoting the flow of air between the top of the ridges (C) present on the surface of the support according to the invention and the sub-tile plate. This embodiment of said support according to the invention is the preferred form of the invention.

Selon une autre forme de réalisation de l'invention, la hauteur entre le sommet d'une crête (C) et le fond d'un creux (cx) présents sur ledit support selon l'invention pourra être supérieure à la hauteur entre le sommet d'une crête (α ou γ) et le fond d'un creux (δ ou β) présents sur ladite plaque sous-tuile. Avec cette forme de réalisation de l'invention, lors de la pose les plaques sous-tuile viendront prendre appui sur le support selon l'invention par mise en contact du sommet des crêtes (C) présentes à la face supérieure dudit support selon l'invention et le fond des creux présent à la face inférieure de la plaque sous-tuile (δ ou β).According to another embodiment of the invention, the height between the apex of a peak (C) and the bottom of a hollow (cx) present on said support according to the invention may be greater than the height between the vertex a peak (α or γ) and the bottom of a hollow (δ or β) present on said sub-tile plate. With this embodiment of the invention, during the laying the sub-tile plates will come to bear on the support according to the invention by contacting the top of the crests (C) present at the upper face of said support according to the invention and the bottom of the recesses present at the lower face of the sub-tile plate (δ or β).

Selon encore une autre forme de réalisation de l'invention, la hauteur entre le sommet d'une crête (C) et le fond d'un creux (cx) présents sur ledit support selon l'invention pourra être égale à la hauteur entre le sommet d'une crête (α ou γ) et le fond d'un creux (δ ou β) présents sur ladite plaque sous-tuile. Avec cette forme de réalisation de l'invention, lors de la pose les plaques sous-tuile viendront prendre appui sur le support selon l'invention par mise en contact du sommet des crêtes présentes à la face inférieure de ladite plaque sous-tuile (γ ou α) et le fond des creux (cx) dudit support selon l'invention et par mise en contact du sommet des crêtes (C) présentes à la face supérieure dudit support selon l'invention et le fond des creux présent à la face inférieure de la plaque sous-tuile (δ ou β).According to yet another embodiment of the invention, the height between the apex of a peak (C) and the bottom of a hollow (cx) present on said support according to the invention may be equal to the height between the peak of a ridge (α or γ) and the bottom of a hollow (δ or β) present on said sub-tile plate. With this embodiment of the invention, during the laying the sub-tile plates will come to bear on the support according to the invention by contacting the top of the ridges present at the underside of said sub-tile plate (γ or α) and the bottom of the recesses (cx) of said support according to the invention and by contacting the top of the crests (C) present at the upper face of said support according to the invention and the bottom of the depressions present at the lower face. of the sub-tile plate (δ or β).

Selon une forme particulière de réalisation de l'invention ladite hauteur entre le sommet d'une crête (C) et le fond d'un creux (cx) pourra être égale à 0, ladite surface supérieure dudit support selon l'invention étant alors plane. Ladite surface supérieure représentant ainsi à elle seule au choix une crête ou un creux.According to a particular embodiment of the invention said height between the top of a peak (C) and the bottom of a hollow (cx) may be equal to 0, said upper surface of said support according to the invention then being plane . Said upper surface thus representing alone a choice ridge or a hollow.

Selon une autre forme particulière de réalisation de l'invention, préférée, ladite hauteur entre le sommet d'une crête (C) et le fond d'un creux (cx) présents sur ledit support selon l'invention pourra être comprise entre 5 et 80 mm, préférentiellement entre 10 et 60 mm, très préférentiellement entre 15 et 35 mm.According to another preferred embodiment of the invention, said height between the apex of a peak (C) and the bottom of a hollow (cx) present on said support according to the invention may be between 5 and 80 mm, preferably between 10 and 60 mm, very preferably between 15 and 35 mm.

On a vu précédemment que la plaque sous-tuiles peut présenter sur l'une de ses faces des crêtes (C) de forme arrondie de rayon de grande taille (grandes crêtes (γ) sur la figure 1) et sur son autre face des crêtes (C) de forme arrondie de rayon de petite taille (petites crêtes (α) sur la figure 1). Cette différence de rayons des crêtes peut permettre pour une même plaque sous-tuiles et selon l'orientation dans laquelle on la positionne, de réaliser des couvertures en tuile canal à 1 ou 2 tuiles.We saw previously that the plate under-tiles can present on one of its faces ridges (C) of rounded shape of large radius (large ridges (γ) on the figure 1 ) and on its other side ridges (C) of rounded shape of small radius (small ridges (α) on the figure 1 ). This difference in ridge radius can allow for the same plate under tiles and according to the orientation in which it is positioned, to achieve roof tiles channel 1 or 2 tiles.

Pour la réalisation d'une couverture à 1 tuile, la plaque sous-tuiles pourra être positionnée sur le support selon l'invention avec ses grandes crêtes (γ) orientées vers le haut ce qui pourra permettre de juxtaposer côte à côte 2 rangs de tuiles (tuiles de couvert) orientées faces ouvertes vers le bas (dos vers le haut) en appui sur 2 grandes crêtes (γ, Figure 1) de ladite plaque sous-tuile, orientées vers le haut, parallèles et contiguës, sans positionner entre eux un rang de tuiles orientées face ouverte vers le haut (tuiles de courant), l'étanchéité de la toiture étant alors assurée par la plaque sous-tuiles elle-même.For the realization of a cover with 1 tile, the plate under-tiles can be positioned on the support according to the invention with its large peaks (γ) oriented upward which can allow to juxtapose side by side 2 rows of tiles (roof tiles) oriented open faces down (back up) resting on 2 large ridges (γ, Figure 1 ) of said sub-tile plate, facing upwards, parallel and contiguous, without positioning between them a row of tiles facing upwards (current tiles), the waterproofing of the roof then being ensured by the sub-tile itself.

Pour la réalisation d'une couverture à 2 tuiles, la plaque sous-tuiles pourra être positionnée sur le support selon l'invention avec les petites crêtes (α) orientées vers le haut ce qui pourra permettre, pour renforcer l'étanchéité de la toiture, de positionner un rang de tuile (tuiles de courant) orientées face ouverte vers le haut et donc dos vers le bas en appui dans le fond du creux (β sur la figure 1) de ladite plaque sous-tuile et de juxtaposer côte à côte 2 rangs de tuiles (tuiles de couvert) orientées faces ouvertes vers le bas (dos vers le haut) en appui sur les 2 petites crêtes (α) orientées vers le haut, parallèles et contiguës, et encadrant ledit creux (β) portant lesdites tuiles de couvert.For the realization of a cover with 2 tiles, the plate under-tiles can be positioned on the support according to the invention with the small peaks (α) directed upwards which will allow, to reinforce the waterproofness of the roof , to position a row of tiles (current tiles) oriented face upwards and therefore back down in support in the bottom of the hollow (β on the figure 1 ) of said sub-tile plate and juxtapose side by side 2 rows of tiles (roof tiles) oriented open faces downward (upward back) bearing on the 2 small peaks (α) facing upwards, parallel and contiguous, and flanking said hollow (β) carrying said roof tiles.

Quelle que soit la forme de montage choisie (1 ou 2 tuiles) il est possible que la plaque sous-tuiles repose sur un support selon l'invention dont la face supérieure pourrait être lisse. Cependant on conçoit que si l'on veut rendre le positionnement de ladite plaque sous-tuiles aisé et rapide, il pourrait être un grand avantage que la face supérieure dudit support selon l'invention, destinée à recevoir ladite plaque sous-tuiles comprenne des creux (cx) en forme de gouttières (G) courant sur toute la longueur du grand axe dudit support, parallèles et séparées de fait par des crêtes (C) et destinées à recevoir en appui sur leur fond (G1, G2), le sommet des crêtes (α, γ) de la face inférieure d'une plaque sous-tuiles (PsT).Whatever the form of mounting chosen (1 or 2 tiles) it is possible that the sub-tiles plate rests on a support according to the invention, the upper face could be smooth. However, it will be appreciated that, if it is desired to make the positioning of said sub-tile plate quick and easy, it could be a great advantage for the upper face of said support according to the invention, intended to receive said sub-tile plate, to comprise hollow spaces. (cx) in the form of gutters (G) running along the entire length of the major axis of said support, parallel and separated in fact by crests (C) and intended to receive in abutment on their bottom (G1, G2), the top of the peaks (α, γ) of the underside of a sub-tile plate (PsT).

Ainsi dans une forme de réalisation particulière ledit support selon l'invention pourra comprendre sur sa face supérieure des creux (cx) en forme de gouttières (G), parallèles et courant sur toute la longueur du grand axe dudit support. Ces creux (cx) pourront avoir pour objet de recevoir une plaque sous-tuiles en appui sur les crêtes (α, γ) de sa face inférieure.Thus, in a particular embodiment, said support according to the invention may comprise on its upper face recesses (cx) in the form of gutters (G), parallel and running along the entire length of the major axis of said support. These recesses (cx) may have the purpose of receiving a sub-tile plate resting on the peaks (α, γ) of its lower face.

Selon l'invention lesdits creux pourront avoir un profil en coupe en arc de cercle de rayon au moins égal au rayon des grandes crêtes (γ) de ladite plaque sous-tuiles, préférentiellement égal au rayon des grandes crêtes (γ) de ladite plaque sous-tuiles (PsT).According to the invention, said recesses may have a cross-sectional profile in the form of an arc of radius at least equal to the radius of the large peaks (γ) of said sub-tile plate, preferably equal to the radius of the large peaks (γ) of said plate under -tuiles (PsT).

Selon une autre forme de réalisation du support selon l'invention, les creux (cx) pourront avoir un profil en coupe en arc de cercle de rayon au moins égal au rayon des petites crêtes (α) de ladite plaque sous-tuiles, préférentiellement égal au rayon des petites crêtes (α) de ladite plaque sous-tuiles (PsT).According to another embodiment of the support according to the invention, the hollows (cx) may have a sectional profile in an arc of a radius of radius at least equal to radius of the small peaks (α) of said sub-tile plate, preferably equal to the radius of the small peaks (α) of said sub-tile plate (PsT).

On comprend que dans ces formes de réalisation particulières les plaques sous-tuiles (PsT) pourront venir se positionner aisément dans les creux (cx) dudit support selon l'invention facilitant ainsi pour le poseur leur positionnement et ce que la face de ladite plaque sous-tuiles en contact avec ladite face supérieure dudit support selon l'invention présente des grandes crêtes (γ) ou des petites crêtes (α). Mais ces formes de réalisation particulières nécessitent que ledit support selon l'invention existe sous deux formes distinctes une forme avec des creux (cx) d'un diamètre au moins égal au diamètre des petites crêtes (α) de la plaque sous-tuiles et une forme avec des creux (cx) d'un diamètre au moins égal au diamètre des grandes crêtes (γ) de la plaque sous-tuiles.It is understood that in these particular embodiments, the sub-tile plates (PsT) can easily be positioned in the recesses (cx) of said support according to the invention thus facilitating for the installer their positioning and that the face of said plate under -tuiles in contact with said upper face of said support according to the invention has large ridges (γ) or small ridges (α). But these particular embodiments require that said support according to the invention exists in two distinct forms a shape with recesses (cx) of a diameter at least equal to the diameter of the small peaks (α) of the sub-tile plate and a forms with hollows (cx) of a diameter at least equal to the diameter of the large peaks (γ) of the sub-tile plate.

On conçoit alors qu'il pourrait être un autre avantage que dans une autre forme de réalisation dudit support selon l'invention ladite zone de contact entre la plaque sous-tuiles et ledit support, sur ledit support, soit d'une forme apte à recevoir indifféremment en appui soit des petites crêtes (α) soit des grandes crêtes (γ) d'une plaque sous-tuiles. Ainsi une seule forme de support selon l'invention serait à prévoir.It is then conceivable that there could be another advantage than in another embodiment of said support according to the invention, said zone of contact between the sub-tile plate and said support, on said support, is of a form able to receive indifferently in support of either small ridges (α) or large ridges (γ) of a sub-tile plate. Thus only one form of support according to the invention would be expected.

Ainsi on comprend que dans cette forme de réalisation ladite face supérieure dudit support selon l'invention peut comprendre des creux (cx) en forme de gouttières (G), ladite gouttière pouvant présenter un profil en plusieurs arcs de cercles imbriqués les uns dans les autres.Thus it is understood that in this embodiment said upper face of said support according to the invention may comprise troughs (cx) in the form of gutters (G), said trough may have a profile in several arcs of circles nested within each other .

Ainsi selon une forme de réalisation de l'invention, ladite face supérieure dudit support selon l'invention peut comprendre des creux (cx) en forme de gouttières (G), orientées selon le grand axe longitudinal dudit support, pouvant présenter un profil en arc de cercle et pouvant comprendre en outre une seconde gouttière (G2) orientée selon le même grand axe longitudinal dudit support et positionnées dans le fond de ladite première gouttière (G1). On comprend que dans cette forme de réalisation ladite gouttière (G) pourra présenter un profil formé de 2 arcs de cercle de rayons différents (G1, G2) imbriqués l'un dans l'autre, leurs 2 centres (O et o) pouvant être positionnés sur l'axe de symétrie des gouttières G1 et G2. Il s'agit là de la forme la plus simple envisageable pour les gouttières d'un support selon l'invention apte à recevoir indifféremment une plaque sous-tuiles en appui sur ces petites crêtes (α) ou sur ces grandes crêtes (γ).Thus according to one embodiment of the invention, said upper face of said support according to the invention may comprise troughs (cx) in the form of gutters (G), oriented along the major longitudinal axis of said support, which may have an arcuate profile. circle and may further comprise a second channel (G2) oriented along the same major longitudinal axis of said support and positioned in the bottom of said first gutter (G1). It is understood that in this embodiment said gutter (G) may have a profile formed of 2 arcs of different radii (G1, G2) nested one inside the other, their 2 centers (O and o) can be positioned on the axis of symmetry of gutters G1 and G2. This is the simplest form possible for the gutters of a support according to the invention adapted to receive indifferently a sub-tile plate resting on these small peaks (α) or on these large peaks (γ).

Mais cette forme peut rendre délicate la pose des plaques sous-tuiles dans la mesure où elle n'a qu'une tolérance faible vis-à-vis de la précision des formes de la plaque sous-tuiles.But this shape can make it difficult to lay tiles under tiles as it has only a low tolerance for the accuracy of the shapes of the tile underlay.

Ainsi selon encore une autre forme de réalisation particulière de l'invention il est possible de jouer sur la forme des gouttières G1 et G2 pour admettre une tolérance vis-à-vis de la précision des formes de la plaque sous-tuiles plus grandes.Thus according to yet another particular embodiment of the invention it is possible to play on the shape of the gutters G1 and G2 to accept a tolerance vis-à-vis the accuracy of the shapes of the plate under-tiles larger.

Ainsi on peut imaginer que la gouttière G1 (gouttière recevant les grandes crêtes (γ)) puisse être formée de deux arcs de cercles de rayons (R) identiques et de centre (O) unique lesdits 2 arcs de cercles pouvant être séparés par une seconde gouttière G2 (gouttière recevant les petites crêtes (α)) elle-même pouvant être formée par un arc de cercle de rayon (r) unique et de centre (o) unique, G2 pouvant être positionnée symétriquement selon le grand axe de G1.Thus one can imagine that the gutter G1 (gutter receiving large ridges (γ)) can be formed of two arcs of circles of radii (R) identical and center (O) unique said two arcs of circles can be separated by a second gutter G2 (gutter receiving the small peaks (α)) itself being able to be formed by an arc of a circle of radius (r) and single center (o) single, G2 can be positioned symmetrically along the major axis of G1.

On peut également imaginer que la gouttière G1 (gouttière recevant les grandes crêtes (γ)) puisse être formée de deux arcs de cercles de rayons (R) identiques mais de centres (O1 et O2) différents, lesdits 2 arcs de cercle pouvant être séparés par la seconde gouttière G2 (gouttière recevant les petites crêtes (α)) elle-même pouvant être formée par un arc de cercle de rayon (r) unique et de centre (o) unique, G2 pouvant être positionnée symétriquement selon le grand axe de G1.One can also imagine that the gutter G1 (gutter receiving the large ridges (γ)) can be formed of two arcs of circles of identical radii (R) but different centers (O1 and O2), said 2 arcs of a circle being separable by the second gutter G2 (gutter receiving the small peaks (α)) itself which can be formed by an arc of a circle of radius (r) and single center (o) single, G2 can be positioned symmetrically along the major axis of G1.

On peut encore imaginer que la gouttière G1 (gouttière recevant les grandes crêtes (γ)) puisse être formée de deux arcs de cercles de rayons (R) identiques mais de centres (O1 et O2) différents, lesdits 2 arcs de cercle pouvant être séparés par la seconde gouttière G2 (gouttière recevant les petites crêtes (α)) elle-même pouvant être formée par deux arcs de cercles de rayons (r) identiques mais de centres (o1 et o2) différents, G2 pouvant être positionnée symétriquement selon le grand axe de G1.One can still imagine that the gutter G1 (gutter receiving the large ridges (γ)) can be formed of two arcs of circles of identical radii (R) but different centers (O1 and O2), said two arcs of circle being separable by the second gutter G2 (gutter receiving small ridges (α)) itself which can be formed by two arcs of circles of rays (r) identical but different centers (o1 and o2), G2 can be positioned symmetrically according to the large axis of G1.

Enfin on peut aussi imaginer que la gouttière G1 (gouttière recevant les grandes crêtes (γ)) puisse être formée de deux arcs de cercles de rayons (R) identiques et de centre (O) unique lesdits 2 arcs de cercles pouvant être séparés par une seconde gouttière G2 (gouttière recevant les petites crêtes (α)) elle-même pouvant être formée par deux arcs de cercles de rayons (r) identiques mais de centres (o1 et o2) différents, G2 pouvant être positionnée symétriquement selon le grand axe de G1.Finally we can also imagine that the gutter G1 (gutter receiving the large ridges (γ)) can be formed of two arcs of circles of radii (R) identical and center (O) unique said 2 arcs of circles can be separated by a second gutter G2 (gutter receiving small ridges (α)) itself which can be formed by two arcs of circles of identical radii (r) but of different centers (o1 and o2), G2 being positionable symmetrically along the major axis of G1.

On notera que si les rayons desdits arcs de cercles peuvent être de toutes longueurs, selon une forme préférée de l'invention lesdits rayons des gouttières G1 et G2 peuvent être sensiblement égaux, voire égaux, respectivement aux rayons des crêtes grandes (γ) ou petites (α) de la plaque sous-tuiles qui va venir prendre appui sur lesdites gouttières.Note that if the radii of said arcs of circles can be of any length, according to a preferred form of the invention said gutter rays G1 and G2 may be substantially equal to or even equal to the rays of large (γ) or small crests respectively (α) of the sub-tile plate which will come to bear on said gutters.

Selon l'invention et quelle que soit la forme de réalisation de l'invention, le rayon de ladite première gouttière (G1), qu'elle soit en un arc de cercle de centre unique ou en 2 arcs de cercle de centres différents, pourra être compris entre 30 et 80 mm préférentiellement entre.60 et 70 mm.According to the invention and whatever the embodiment of the invention, the radius of said first gutter (G1), whether in a single center arc or in two arcs of different centers, may be between 30 and 80 mm, preferably between 60 and 70 mm.

De même selon encore l'invention et quelle que soit la forme de réalisation de l'invention, le rayon de ladite seconde gouttière (G2) qu'elle soit en un arc de cercle de centre unique ou en 2 arcs de cercle de centres différents, pourra être compris entre 20 et 60 mm préférentiellement entre 40 et 50 mm.Similarly according to the invention and regardless of the embodiment of the invention, the radius of said second gutter (G2) that it is a single center arc or two arcs of different centers may be between 20 and 60 mm, preferably between 40 and 50 mm.

Selon encore un autre mode de réalisation de l'invention, ledit support peut en outre comprendre sur ses faces latérales et/ou sur ses face amont et aval, des moyens aptes à coopérer entre eux afin d'assurer un bon positionnement et un bon ajustement d'un support par rapport au support directement positionné à côté (moyens de jonction). Selon l'invention lesdits moyens de jonction peuvent être tout moyen connu de l'homme du métier comme par exemple une protubérance faisant saillie sur l'une des faces latérales dudit support et apte à se positionner dans une échancrure présente sur la face latérale contigüe du support lui-même contigu, ladite échancrure étant globalement de même forme, mais en creux, que ledit bourrelet. A titre d'exemple on peut citer, sans limitation, comme couple bourrelet/échancrure un bourrelet en forme de demi cylindre pouvant s'accoupler avec un demi cylindre de même diamètre ou de diamètre légèrement supérieur réalisé en creux sur l'autre face, un bourrelet en forme de parallélépipède pouvant s'accoupler avec un parallélépipède de même dimension ou de dimensions légèrement supérieures réalisé en creux sur l'autre face, un bourrelet de profil triangulaire pouvant s'accoupler avec une empreinte de forme triangulaire de même dimension ou de dimensions légèrement supérieures réalisée en creux sur l'autre face.According to yet another embodiment of the invention, said support may further comprise on its lateral faces and / or on its upstream and downstream faces, means capable of cooperating with each other in order to ensure a good positioning and a good fit. a support relative to the support directly positioned next (junction means). According to the invention, said joining means can be any means known to those skilled in the art, for example a protuberance protruding from one of the lateral faces of said support and able to be positioned in an indentation present on the contiguous lateral face of the device. support itself contiguous, said notch being generally of the same shape, but hollow, that said bead. By way of example, one can cite, without limitation, as a bead / notch couple a bead in the form of a half-cylinder which can couple with a half-cylinder of the same diameter or of a slightly greater diameter made in recess on the other face, a parallelepiped-shaped bead that can mate with a parallelepiped of the same dimension or slightly larger dimensions hollowed on the other side, a triangular profile bead that can mate with a triangular-shaped imprint of same dimension or slightly larger dimensions made hollow on the other side.

L'homme du métier comprend sans difficulté que lesdits moyens de jonction peuvent être un ou plusieurs, identiques ou différents, sur une même face, tant sur la longueur que sur la hauteur de ladite face, et peuvent être de longueur égale à la longueur de ladite face ou plus courts. On comprend également que la même face peut comprendre en même temps des parties mâles et femelles desdits moyens de jonction en forme de protubérance et en creux.The person skilled in the art easily understands that said connecting means can be one or more, identical or different, on the same face, both along the length and the height of said face, and can be of length equal to the length of said face or shorter. It is also understood that the same face may comprise at the same time male and female parts of said junction means in the form of protrusion and recessed.

Ainsi selon l'invention, ledit support peut comprendre en outre sur au moins une de ses faces latérales et/ou aval et/ou amont, avantageusement sur toutes ses faces latérales et aval et amont des éléments mâles ou femelles d'un moyen de jonction apte à faire coopérer ensemble 2 supports selon l'invention contigus.Thus according to the invention, said support may further comprise on at least one of its lateral faces and / or downstream and / or upstream, advantageously on all its lateral faces and downstream and upstream of the male or female elements of a junction means able to cooperate together 2 supports according to the invention contiguous.

Selon encore une autre forme de réalisation de l'invention ledit support peut outre comprendre au moins un renfort pour assurer sa rigidité. Ledit renfort peut être de toute forme et en toute matière compatible avec sa fonction. Il peut être disposé tant latéralement que longitudinalement par rapport audit support. Il peut être unique ou multiple. Préférentiellement selon l'invention ledit support comprendra au moins 2 renforts positionnés longitudinalement parallèlement l'un par rapport à l'autre au niveau de la face inférieur dudit support, ledit renfort pouvant être par exemple un rail de profil en U et en acier inoxydable.According to yet another embodiment of the invention, said support may further comprise at least one reinforcement to ensure its rigidity. Said reinforcement can be of any shape and in any material compatible with its function. It can be arranged both laterally and longitudinally with respect to said support. It can be single or multiple. Preferably, according to the invention, said support will comprise at least two reinforcements positioned longitudinally parallel to one another at the level of the underside of said support, said reinforcement possibly being, for example, a U-shaped profile rail and stainless steel.

Selon l'invention ledit renfort peut être positionné sur au moins une des faces dudit support, ou encore noyé dans sa masse. Préférentiellement selon l'invention ledit renfort pourra être noyé dans la masse dudit support.According to the invention said reinforcement can be positioned on at least one of the faces of said support, or embedded in its mass. Preferably, according to the invention, said reinforcement may be embedded in the mass of said support.

Selon encore une autre forme particulière de réalisation de l'invention, ledit support isolant peut en outre comprendre lié à sa face inférieure un élément de décoration. Tout mode de liaison connu de l'homme du métier peut être utilisé selon l'invention, pour lier ledit élément de décoration audit support isolant selon l'invention. A titre d'exemple on pourra citer le vissage, le clipsage ou encore le collage. Avantageusement selon l'invention, l'élément de décoration sera collé à ladite face inférieure dudit support isolant.According to yet another particular embodiment of the invention, said insulating support may further comprise attached to its underside a decorative element. Any binding method known to those skilled in the art can be used according to the invention for bonding said decorative element to said insulating support according to the invention. By way of example, mention may be made of screwing, clipping or gluing. Advantageously according to the invention, the decorative element will be bonded to said lower face of said insulating support.

Par élément de décoration on entend tout moyen permettant de donner à la face inférieure dudit support selon l'invention, un aspect plaisant au regard. Selon l'invention et sans limitation, ledit élément de décoration peut être une ou plusieurs feuille(s) de papier, de plastique, une ou plusieurs plaque(s) de bois, de fer, de plâtre, de plastique, de résine, etc. Une forme de réalisation particulièrement préférée de l'invention est un support isolant selon l'invention comprenant à sa face inférieure une plaque de plâtre avantageusement collée.By decoration element means any means for giving the underside of said support according to the invention, a pleasant aspect to look. According to the invention and without limitation, said decorative element may be one or more sheet (s) of paper, plastic, one or more plate (s) of wood, iron, plaster, plastic, resin, etc. A particularly preferred embodiment of the invention is an insulating support according to the invention comprising on its underside a gypsum board advantageously bonded.

La description qui précède décrit un support de plaque sous-tuiles destiné à rendre plus facile le positionnement de l'isolant et de la plaque sous-tuiles au cours de la réalisation d'une toiture. Cette description montre que l'invention concerne un support dissymétrique dans sa forme puisque bien que de forme globalement parallélépipédique rectangle il n'en présente pas moins une pente, à tout le moins une pente dans le fond des gouttières présentes sur sa face supérieure. Cette pente implique lors de la pose un sens particulier de mise en place dudit support qui comme on l'a vu précédemment, veut que dans le sens longitudinal deux supports contigus soit accolés l'un à l'autre par leurs faces aval et amont, le support aval présentant au support amont sa face amont, étant entendu que ladite face amont est celle dont au moins la profondeur des gouttières est supérieure à ladite profondeur des gouttières de la face aval dudit support amont.The above description describes a sub-tile plate support intended to make it easier to position the insulation and the sub-tile plate during the production of a roof. This description shows that the invention relates to an asymmetrical support in its form since although of generally rectangular parallelepiped shape, it nonetheless has a slope, at least a slope in the bottom of the gutters present on its upper face. This slope implies during the laying a particular direction of installation of said support which as we have seen previously, wants that in the longitudinal direction two contiguous supports are contiguous to each other by their downstream and upstream faces, the downstream support presenting to the upstream support its upstream face, it being understood that said upstream face is that of which at least the depth of the gutters is greater than said depth of the gutters of the downstream face of said upstream support.

Ainsi l'invention a aussi pour objet un procédé de réalisation de toiture comprenant l'utilisation d'un support de plaque sous-tuiles selon l'invention.Thus the invention also relates to a roofing method comprising the use of a sub-tile plate support according to the invention.

L'invention a encore pour objet une toiture comprenant au moins un support selon l'invention.The invention also relates to a roof comprising at least one support according to the invention.

Il est possible lors de la fabrication dudit support selon l'invention de prévoir à la surface supérieure dudit support différents marquages particulièrement des marquages destinés à faciliter le travail du poseur. Lesdits marquages peuvent être des guides de coupe ou encore des indications du sens de pose dudit support.It is possible during the manufacture of said support according to the invention to provide on the upper surface of said support different markings particularly markings intended to facilitate the work of the installer. Said markings may be cutting guides or indications of the direction of installation of said support.

On notera donc la dissymétrie de ladite plaque avec en 11 le sommet d'une petite crête (α) qui peut également être référencé comme le fond (sur l'autre face) du petit creux (δ) correspondant et en 12 le sommet d'une grande crête (γ) qui peut également être référencé comme le fond (sur l'autre face) du grand creux (β) correspondant.By reference to the figure 1 which represents the profile of a sub-tile plate having 5 small ridges (α) and 5 large ridges (γ) and in fact 5 large depressions (P) and 5 small recesses (δ) delimited with respect to said peaks. Note therefore the dissymmetry of said plate with 11 the top of a small peak (α) which can also be referenced as the bottom (on the other side) of the corresponding small hollow (δ) and 12 the top of a large peak (γ) which can also be referenced as the bottom (on the other side) of the corresponding large hollow (β).

Par référence à la figure 2 qui représente une vue en perspective du support selon l'invention (20) on note en (21) la face supérieure, en (22) la face inférieure, en (23) une des 2 faces latérales, en (24) la face aval et en (25) la face amont dudit support (20). On note également la présence sur la face supérieure de grandes crêtes (C) et de creux (cx).By reference to the figure 2 which represents a perspective view of the support according to the invention (20) is noted in (21) the upper face, in (22) the lower face, in (23) one of the two lateral faces, in (24) the downstream face and in (25) the upstream face of said support (20). We also note the presence on the upper face of large ridges (C) and hollow (cx).

On note encore en (26) 2 renforts longitudinaux et en (27) sur une des faces latérales (23), deux échancrures parallèles de forme semi-cylindrique constituant la partie femelle d'un moyen destiné à assurer un bon positionnement et un bon ajustement d'un support (20) par rapport au support contigu, la partie mâle dudit moyen étant représentée sur l'autre face latérale en (28) et se présentant sous la forme de 2 bourrelets de forme semi-cylindrique parallèles et courant sur toute la longueur de ladite face latérale.We still note (26) 2 longitudinal reinforcements and (27) on one of the side faces (23), two parallel notches of semi-cylindrical shape constituting the female part of a means for ensuring a good positioning and a good fit a support (20) relative to the contiguous support, the male part of said means being shown on the other side face (28) and in the form of 2 beads of parallel semi-cylindrical shape and running over the entire length of said side face.

On note enfin en (29) la présence d'un élément de décoration sous la forme d'une plaque recouvrant la totalité de la surface inférieure dudit support selon l'invention. On note surtout la présence du côté aval dudit support la présence d'évidements E positionnés au droit des creux (cx). On comprend donc que dans la forme de réalisation représentée à cette figure la surface de la face supérieure est plane et constituée par le sommet des crêtes (C) et que les fonds des creux forment une pente orientée dans le sens de la descente de la face aval (24) vers la face amont (25). Les évidements (E) ont pour objet de rattraper la pente et de permettre le positionnement d'une plaque sous-tuiles positionnée en aval dont la partie amont viendra se loger dans lesdits évidements. On comprend alors que le fond de l'évidement peut se trouver à la même distance de surface inférieure que le fond du creux (cx) au niveau de la face amont (25).Finally, note (29) the presence of a decorative element in the form of a plate covering the entire lower surface of said support according to the invention. It is especially noted the presence of the downstream side of said support the presence of recesses E positioned to the right of the recesses (cx). It is therefore understood that in the embodiment shown in this figure the surface of the upper face is flat and formed by the top of the ridges (C) and that the bottom of the hollows form a slope oriented in the direction of descent from the downstream face (24) to the upstream face (25). The recesses (E) are intended to make up the slope and to allow the positioning of a sub-tile plate positioned downstream, the upstream portion will be housed in said recesses. It is then understood that the bottom of the recess may be at the same distance from the lower surface as the bottom of the recess (cx) at the upstream face (25).

Par référence à la figure 3 qui représente une vue en coupe du support selon l'invention (30) on note la face supérieure (31), la face inférieure (32), la face aval (34), la face latérale (33) portant la partie mâle d'un moyen de jonction (38) se présentant sous la forme de 2 bourrelets de forme semi-cylindrique parallèles et sur l'autre face latérale, 2 échancrures parallèles (37) de forme semi-cylindrique constituant la partie femelle d'un moyen de jonction, destiné à assurer un bon positionnement et un bon ajustement d'un support (30) par rapport au support (30) contigu. On note également la présence sur la face supérieure de grandes crêtes (C) et de creux (cx). On note encore en (36), 2 renforts longitudinaux et en (39) un élément de décoration sous la forme d'une plaque recouvrant la totalité de la surface inférieure dudit support selon l'invention (30).

We also note the presence on the upper face of large ridges (C) and hollow (cx). There are still (36), 2 longitudinal reinforcements and (39) a decorative element in the form of a plate covering the entire lower surface of said support according to the invention (30). The figures also show the representation of the height (h) between the bottom of a hollow and the lower face and the indication of the axis of symmetry passing through the bottom of the recesses.

On note surtout en A la forme particulière du creux (cx) en forme de gouttière, montrant que ledit creux est globalement composé d'un premier profil formant ainsi la première gouttière (G1) et d'un second profil formant ainsi une seconde gouttière (G2) positionnée dans le fond de ladite première gouttière (G1). Les figures 3A1 à 3A4 représentent les différentes formes possibles de réalisation des gouttières présentes sur ledit support.We note especially in A the particular shape of the trough (cx) shaped gutter, showing that said hollow is generally composed of a first profile thus forming the first gutter (G1) and a second profile thus forming a second gutter ( G2) positioned in the bottom of said first gutter (G1). The Figures 3A1 to 3A4 represent the different possible embodiments of the gutters present on said support.

En A1 le creux (cx) est formé d'une première gouttière (G1) elle-même formée de deux arcs de cercles de rayons (R) identiques et de centre (O) unique lesdits 2 arcs de cercles étant séparés par une seconde gouttière (G2) elle-même formée par un arc de cercle de rayon (r) unique et de centre (o) unique, G2 étant positionnée symétriquement selon le grand axe de G1.In A1 the hollow (cx) is formed of a first gutter (G1) itself formed of two arcs of circles of rays (R) identical and center (O) unique said two arcs of circles being separated by a second gutter (G2) itself formed by an arc of a single radius (r) and center (o) single, G2 being positioned symmetrically along the major axis of G1.

Par référence à la figure 4 qui représente une vue en coupe latérale dudit support selon l'invention (40), ladite coupe passant par le fond d'une gouttière G2. On note la face supérieure (41), la face inférieure (42), la face aval (45) et la face amont (44) et en (49) un élément de décoration sous la forme d'une plaque recouvrant la totalité de la surface inférieure dudit support selon l'invention. On note également la présence d'un moyen de jonction de forme rectangulaire en coupe (491) sur la face aval. 492 et 493 matérialisent le fond de la gouttière (492) et la face supérieure du support selon l'invention (493) On note surtout la présence à la jonction entre la face supérieure (41) et la face aval (45) d'un évidement (E) de forme rectangulaire et de profondeur (y).By reference to the figure 4 which represents a side sectional view of said support according to the invention (40), said section passing through the bottom of a gutter G2. The upper face (41), the lower face (42), the downstream face (45) and the upstream face (44) are noted and in (49) a decorative element in the form of a plate covering the whole of the lower surface of said support according to the invention. Note also the presence of a junction means of rectangular sectional shape (491) on the downstream face. 492 and 493 materialize the bottom of the gutter (492) and the upper face of the support according to the invention (493). It is especially noted the presence at the junction between the upper face (41) and the downstream face (45) of a recess (E) of rectangular shape and depth (y).

Par référence à la figure 5 qui représente une vue en coupe frontale d'une toiture 1 tuile (A) ou 2 tuiles (B), on note la face supérieure (51) et la face inférieure (52) d'un support selon l'invention (50). On note également la présence d'une plaque sous-tuiles (PsT) orientée en (A) pour recevoir les tuiles (T) d'une couverture réalisée en mode 1 tuile, grandes crêtes (γ) orientées vers le haut, et en (B) pour recevoir les tuiles (T) d'une couverture réalisée en mode 2 tuiles, petites crêtes (α) orientées vers le haut.By reference to the figure 5 which represents a frontal sectional view of a roof 1 tile (A) or 2 tiles (B), we note the upper face (51) and the lower face (52) of a support according to the invention (50). We also note the presence of a subtile plate (PsT) oriented in (A) to receive the tiles (T) of a cover made in mode 1 tile, large peaks (γ) oriented upwards, and ( B) to receive the tiles (T) of a cover made in mode 2 tiles, small peaks (α) facing upwards.

On note qu'en (A) la plaque sous-tuiles (PsT) prend appui sur ledit support de l'invention (50) dans le fond d'une seconde gouttière (G2) positionnée dans le fond d'une première gouttière de la face supérieure (51) par l'intermédiaire du sommet de ses petites crêtes (α), ledit fond étant en arc de cercle d'un rayon identique au profil en arc de cercle de la petite crête (α) de la plaque sous-tuiles (PsT).It is noted that in (A) the sub-tile plate (PsT) is supported on said support of the invention (50) in the bottom of a second channel (G2) positioned in the bottom of a first gutter of the upper face (51) via the apex of its small ridges (α), said bottom being in an arc of a radius identical to the arcuate profile of the small ridge (α) of the sub-tile plate (PsT).

On note qu'en (B) la plaque sous-tuiles (PsT) prend appui sur ledit support de l'invention (50) sur les bords latéraux d'une première gouttière (G1) de la face supérieure (51) par l'intermédiaire des bords latéraux de ses grandes crêtes (γ), lesdits bords latéraux de ladite première gouttière (G1) étant formés de 2 arcs de cercle d'un rayon quasi-identique au profil semi-circulaire de la grande crête (γ) de la plaque sous-tuiles (PsT).It is noted that in (B) the sub-tile plate (PsT) bears on said support of the invention (50) on the lateral edges of a first gutter (G1) of the upper face (51) by the intermediate of the lateral edges of its large ridges (γ), said lateral edges of said first gutter (G1) being formed of 2 arcs of a radius almost identical to the semicircular profile of the large ridge (γ) of the Under-tile plate (PsT).

Par référence à la figure 6 qui représente une vue latérale de l'agencement de 2 supports (60) selon l'invention longitudinalement contigus et des plaques sous-tuiles (PsT) qui les recouvrent on note particulièrement la zone de recouvrement R2 des 2 plaques sous-tuiles où l'on remarque que la plaque sous-tuiles amont recouvre la plaque sous-tuiles aval et que la plaque sous-tuiles aval repose sur l'évidement E. On note que la présence de la pente de la surface supérieure de la plaque aval induit l'appui de la plaque sous-tuiles aval sur l'évidement E de la plaque sous-tuiles amont. Cela a pour conséquence que les lignes longitudinales (L1 et L2) de crêtes (C) de 2 plaques sous-tuiles contigües sont parallèles alors que si les supports n'étaient pas ceux de l'invention mais des supports standards de forme parallélépipédique rectangle dont la face supérieure et la face inférieure sont parallèles les lignes longitudinales de crêtes de 2 plaques sous-tuiles contigües ne seraient pas parallèles du fait du recouvrement nécessaires des 2 plaques contigües. On notera que les 2 lignes de crêtes L1 et L2, si elles sont parallèles entre elles, ne sont pas parallèles à la face inférieure desdits supports selon l'invention qui les supportent.By reference to the figure 6 which represents a side view of the arrangement of 2 supports (60) according to the invention longitudinally contiguous and subtile plates (PsT) which cover them is particularly noted the recovery zone R2 of the 2 sub-tiles plates where the it is noted that the upstream sub-tile plate covers the downstream sub-tile plate and that the downstream sub-tile plate rests on the recess E. It is noted that the presence of the slope of the upper surface of the downstream plate induces the support of the downstream sub-tile plate on the recess E of the upstream sub-tile plate. This has the consequence that the longitudinal lines (L1 and L2) of crests (C) of two contiguous sub-tile plates are parallel whereas if the supports were not those of the invention but standard rectangular parallelepiped-shaped supports of which the upper face and the lower face are parallel the longitudinal lines of crests of two contiguous sub-tile plates would not be parallel due to the necessary overlap of the two adjacent plates. Note that the two lines of ridges L1 and L2, if they are parallel to each other, are not parallel to the underside of said supports according to the invention which support them.

Par référence à la figure 7 qui représente une vue en perspective d'un assemblage de plusieurs supports selon l'invention et de plaques sous-tuiles, on note la juxtaposition tant longitudinale que latérale des supports selon l'invention (70) et le positionnement de quelques plaques sous-tuiles PsT.By reference to the figure 7 which represents a perspective view of an assembly of several supports according to the invention and of sub-tile plates, the longitudinal and lateral juxtaposition of the supports according to the invention (70) and the positioning of some sub-tile plates are noted. PST.

On remarque les faces supérieures (71), latérales (73) et aval (74) desdits supports (70). On note encore le recouvrement latéral (R1) et le recouvrement longitudinal (R2) d'une plaque sous-tuiles avec 2 plaques sous-tuiles qui lui sont contigües. On note en particulier en B l'évidement E présent sur la face supérieure d'un support selon l'invention au niveau du bord de ladite face supérieure avec la face aval dudit support. On note que la plaque sous-tuiles prenant appui sur un support amont en B1 vient recouvrir par débordement la plaque sous-tuiles aval en R2. Mais comme au point de recouvrement (B) la face aval dudit support amont et la face amont dudit support aval ont la même hauteur du fait de l'évidement ménagé dans ledit support amont, la partie débordante de ladite plaque sous-tuiles aval vient prendre appui sur ledit évidement (E) ménagé dans ledit support amont.Note the upper faces (71), side (73) and downstream (74) of said supports (70). We still note the lateral overlap (R1) and the longitudinal overlap (R2) of a sub-tile plate with 2 sub-tile plates which are contiguous to it. In particular, B denotes the recess E present on the upper face of a support according to the invention at the edge of said upper face with the downstream face of said support. It is noted that the sub-tile plate bearing on an upstream support B1 overflows over the plate sub-tiles downstream R2. But as at the point of overlap (B) the downstream face of said upstream support and the upstream face of said downstream support have the same height because of the recess in said upstream support, the projecting portion of said downstream sub-tile plate comes to take bearing on said recess (E) formed in said upstream support.
