Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention selon la revendication 1 est relative à une structure de bâtiment légère. Elle trouve au moins une application particulièrement avantageuse dans le domaine des vérandas.The present invention according to claim 1 relates to a lightweight building structure. It finds at least one particularly advantageous application in the field of verandas.

ARRIERE-PLAN TECHNOLOGIQUETECHNOLOGICAL BACKGROUND

Dans le domaine des vérandas, l'utilisation de profilés en aluminium permet de concevoir des structures légères et solides.In the field of verandas, the use of aluminum profiles makes it possible to design light and solid structures.

En particulier, la faible épaisseur de ces profilés en aluminium permet d'augmenter significativement les possibilités d'intégration de différents éléments tels que des gouttières ou des coffres de volets roulants.In particular, the low thickness of these aluminum profiles makes it possible to significantly increase the possibilities for integrating different elements such as gutters or rolling shutter boxes.

Un objectif associé à la conception de vérandas comprenant des profilés en aluminium peut être la recherche d'une architecture d'aspect minimaliste, privilégiant un rendu visuel sans lourdeurs ou éléments massifs.An objective associated with the design of verandas including aluminum profiles can be the search for an architecture with a minimalist appearance, favoring a visual rendering without heaviness or massive elements.

Usuellement une véranda comprend des parois dont la partie supérieure est généralement pourvue d'une panne sablière sur laquelle repose une toiture. Cette partie supérieure peut également recevoir une gouttière ou chéneau et éventuellement un coffre de volet roulant.Usually a veranda includes walls, the upper part of which is generally provided with a top plate on which a roof rests. This upper part can also accommodate a gutter or gutter and possibly a roller shutter box.

La partie visible en haut de la paroi depuis l'extérieur de la véranda est appelée bandeau. Le bandeau peut notamment comprendre la gouttière et le coffre de volet roulant. Il peut être mouluré à des fins décoratives ou au contraire épuré. Le bandeau participe donc à l'esthétique globale de la véranda et constitue en général une jonction visuelle entre la paroi et la toiture.The part visible at the top of the wall from outside the veranda is called the bandeau. The strip may in particular include the gutter and the roller shutter box. It can be molded for decorative purposes or, on the contrary, refined. The strip therefore contributes to the overall aesthetic of the veranda and generally constitutes a visual junction between the wall and the roof.

Plusieurs solutions ont été développées afin d'optimiser l'intégration des coffres de volets roulants et/ou des gouttières au niveau du bandeau.Several solutions have been developed to optimize the integration of rolling shutter boxes and/or gutters at the level of the strip.

Par exemple, le document FR 2796666 B1 divulgue une solution où le coffre de volet roulant est intégralement compris dans l'épaisseur de la paroi et fait office de panne sablière sur laquelle vient s'appuyer la toiture. Une gouttière peut également être montée sur une face externe de ce coffre.For example, the document FR 2796666 B1 discloses a solution where the roller shutter box is entirely included in the thickness of the wall and acts as a top plate on which the roof rests. A gutter can also be mounted on an external face of this box.

Un inconvénient d'une telle solution est d'imposer des contraintes structurales importantes au niveau de la paroi. Par ailleurs, l'ensemble conserve un aspect massif aux yeux d'un observateur extérieur à la véranda.A disadvantage of such a solution is to impose significant structural constraints on the wall. Furthermore, the whole retains a massive appearance in the eyes of an observer outside the veranda.

Les documents référencés « DE 10 2006 055803 A1 », « AT 11536 U1 » et « EP 0 155 243 A2 » décrivent également d'autres structures de véranda.The documents referenced “ DE 10 2006 055803 A1 ", " AT 11536 U1 " And " EP 0 155 243 A2 » also describe other veranda structures.

Un objet de la présente invention est de pallier les inconvénients mentionnés ci-dessus. Plus particulièrement, l'invention vise à proposer une structure de véranda présentant une intégration améliorée, notamment au niveau du bandeau.An object of the present invention is to overcome the disadvantages mentioned above. More particularly, the invention aims to propose a veranda structure having improved integration, particularly at the level of the strip.

RESUME DE L'INVENTIONSUMMARY OF THE INVENTION

L'invention concerne une structure de véranda selon la revendication 1 comprenant au moins : une paroi verticale, une panne sablière présentant une face interne, une toiture comprenant une face supérieure, une face inférieure et au moins un flanc latéral présentant une épaisseur h selon un axe vertical z.The invention relates to a veranda structure according to claim 1 comprising at least: a vertical wall, a top plate having an internal face, a roof comprising an upper face, a lower face and at least one lateral side having a thickness h according to a vertical z axis.

Selon l'invention ladite structure comprend en outre au moins un support de toiture solidaire de la face interne de la panne sablière, et sur lequel prend appui la face inférieure de la toiture, ledit support étant positionné selon l'axe vertical z à une distance d d'encastrement vertical de la toiture relativement à une extrémité supérieure de la panne sablière de sorte à obtenir un recouvrement vertical au moins partiel entre le flanc latéral de la toiture et la face interne de la panne sablière, en regard dudit flanc latéral.According to the invention, said structure further comprises at least one roof support secured to the internal face of the sand pan, and on which the lower face of the roof rests, said support being positioned along the vertical axis z at a distance d vertical embedding of the roof relative to an upper end of the top plate so as to obtain at least partial vertical overlap between the lateral side of the roof and the internal face of the top plate, facing said lateral side.

Cette disposition permet notamment d'encastrer au moins une partie de la toiture sous l'extrémité supérieure de la panne sablière. La toiture se trouve ainsi abaissée verticalement dans un espace intérieur de la véranda délimité par la ou les faces internes de la ou des pannes sablières. Une partie de l'épaisseur de la toiture est dès lors masquée par la ou les pannes sablières pour un observateur situé à l'extérieur de la véranda.This arrangement makes it possible in particular to embed at least part of the roof under the upper end of the top plate. The roof is thus lowered vertically in an interior space of the veranda delimited by the internal face(s) of the top plate(s). Part of the thickness of the roof is therefore masked by the sanding purlin(s) for an observer located outside the veranda.

L'esthétique de la partie haute de la véranda se trouve dès lors nettement améliorée. En particulier, pour une véranda comprenant un bandeau, l'encastrement de la toiture dans l'épaisseur du bandeau réduit significativement l'aspect massif d'une telle véranda. Pour une telle véranda en aluminium, la masse d'aluminium visible est ainsi considérablement minimisée.The aesthetics of the upper part of the veranda are therefore significantly improved. In particular, for a veranda comprising a strip, the embedding of the roof in the thickness of the strip significantly reduces the massive appearance of such a veranda. For such an aluminum veranda, the visible mass of aluminum is thus considerably minimized.

Selon l'invention pour une telle véranda, le bandeau présente un bord supérieur et la face supérieure de la toiture est située sous un plan horizontal passant par ledit bord supérieur, au moins au niveau d'un égout ou d'une partie basse de la toiture. De cette manière, la toiture est totalement occultée au moins au niveau de l'égout par le bandeau pour un observateur extérieur au niveau du sol notamment.According to the invention for such a veranda, the band has an upper edge and the upper face of the roof is located under a horizontal plane passing through said upper edge, at least at the level of a sewer or a lower part of the roofing. In this way, the roof is completely obscured at least at the level of the sewer by the strip for an external observer at ground level in particular.

Selon une possibilité, le bandeau comprend un chéneau, ledit chéneau comprenant un fond, un premier bord intérieur et un deuxième bord extérieur tel que le premier bord intérieur est solidaire de la face externe de la panne sablière ; la face supérieure de la toiture comprend un débord s'étendant au moins en partie dans un plan en prolongement de ladite face supérieure, ledit débord se prolongeant au-dessus et au-delà de la face externe de la panne sablière au moins jusqu'au droit du fond du chéneau, de sorte qu'un écoulement d'eau de pluie depuis la toiture se déverse directement dans le chéneau.According to one possibility, the strip comprises a gutter, said gutter comprising a bottom, a first interior edge and a second exterior edge such that the first interior edge is integral with the exterior face of the top plate; the upper face of the roof comprises an overhang extending at least partly in a plane in extension of said upper face, said overhang extending above and beyond the external face of the top plate at least up to the straight from the bottom of the gutter, so that a flow of rainwater from the roof flows directly into the gutter.

L'évacuation des eaux de pluie est ainsi très efficace, tout en bénéficiant d'une esthétique particulièrement harmonieuse.Rainwater drainage is thus very efficient, while benefiting from a particularly harmonious aesthetic.

En outre, la toiture peut avantageusement comprendre une membrane d'étanchéité s'étendant sur sa face supérieure. De préférence, la membrane s'étend sur toute la face supérieure d'une pluralité de panneaux. De préférence, la membrane s'étend sur toute la face supérieure de tous les panneaux. Outre une fonction d'étanchéité optimisée de la membrane, cela contribue à un aspect esthétique épuré et une amélioration des performances acoustiques.In addition, the roof can advantageously comprise a waterproofing membrane extending over its upper face. Preferably, the membrane extends over the entire upper face of a plurality of panels. Preferably, the membrane extends over the entire upper face of all the panels. In addition to an optimized sealing function of the membrane, this contributes to a clean aesthetic appearance and improved acoustic performance.

Cette membrane d'étanchéité peut être monobloc, réalisée sur mesure en usine par exemple, et peut être assemblée sur chantier par collage sur la face supérieure de la toiture par exemple, afin d'éviter tout perçage pouvant compromettre l'étanchéité.This waterproofing membrane can be in one piece, made to measure in the factory for example, and can be assembled on site by gluing on the upper face of the roof for example, in order to avoid any drilling which could compromise the waterproofing.

La membrane peut se prolonger sur le débord et épouser une forme tridimensionnelle du débord guidant l'eau dans le chéneau. Cette conception permet de poser des toitures dites plates, dont l'inclinaison ne dépasse pas 5°. De préférence une telle toiture plate peut présenter une pente de 2%.The membrane can extend over the overhang and take a three-dimensional shape of the overhang guiding the water into the gutter. This design allows to install so-called flat roofs, the inclination of which does not exceed 5°. Preferably such a flat roof can have a slope of 2%.

Le débord et la membrane peuvent alors avantageusement coopérer pour évacuer les eaux de pluie par débordement.The overhang and the membrane can then advantageously cooperate to evacuate rainwater by overflow.

Optionnellement, le bandeau peut comprendre un coffre pour volet roulant. Ce coffre est situé sous le chéneau, le fond du chéneau formant de préférence un capot supérieur dudit coffre. Plus particulièrement, le coffre est avantageusement agencé contre la face externe de la panne sablière de sorte que l'épaisseur de la paroi selon un axe y horizontal et s'étendant de préférence perpendiculairement à un mur contre lequel est accolé la véranda, ne soit nullement contrainte par la présence éventuelle du coffre.Optionally, the strip can include a roller shutter box. This trunk is located under the gutter, the bottom of the gutter preferably forming an upper cover of said trunk. More particularly, the box is advantageously arranged against the external face of the top plate so that the thickness of the wall along a horizontal y axis and preferably extending perpendicularly to a wall against which the veranda is attached, is in no way constrained by the possible presence of the trunk.

La structure de véranda présente donc une modularité élevée sans contraintes structurales importantes.The veranda structure therefore has high modularity without significant structural constraints.

La structure de véranda selon l'invention présente ainsi un avantage esthétique particulièrement notable, en occultant totalement la toiture dans l'épaisseur du bandeau, et des avantages en termes d'intégration pour une toiture plate notamment et en termes de modularité.The veranda structure according to the invention thus presents a particularly notable aesthetic advantage, by completely obscuring the roof in the thickness of the band, and advantages in terms of integration for a flat roof in particular and in terms of modularity.

Nous allons à présent décrire la présente invention au travers d'un mode de réalisation préféré mais non limitatif.We will now describe the present invention through a preferred but non-limiting embodiment.

En référence à la figure 1, un premier mode de réalisation est une structure de véranda 1 destinée à être adossée à au moins un mur ou une façade de bâtiment 80, la structure 1 comprenant au moins une paroi 2, de préférence trois parois, une toiture 4 et un bandeau 5.In reference to the figure 1 , a first embodiment is a veranda structure 1 intended to be attached to at least one wall or building facade 80, the structure 1 comprising at least one wall 2, preferably three walls, a roof 4 and a strip 5 .

La paroi 2 peut comprendre une structure rigide telle qu'un muret 21, un châssis 22 et/ou des poteaux 23, des vitrages fixes 24 ou coulissants 25, ainsi que des ouvertures battantes, coulissantes ou repliables.The wall 2 may comprise a rigid structure such as a low wall 21, a frame 22 and/or posts 23, fixed glazing 24 or sliding 25, as well as hinged, sliding or folding openings.

Le muret 21 peut éventuellement s'étendre verticalement sur toute la hauteur de la paroi 2, et soutenir directement la toiture 4 (non illustré).The low wall 21 can possibly extend vertically over the entire height of the wall 2, and directly support the roof 4 (not illustrated).

La toiture 4 est de préférence une toiture plate dont l'inclinaison par rapport à un plan horizontal n'excède pas 5 degrés. La pente de la toiture 4 est de préférence comprise entre 0 et 9%, de préférence sensiblement égale à 2%.The roof 4 is preferably a flat roof whose inclination relative to a horizontal plane does not exceed 5 degrees. The slope of the roof 4 is preferably between 0 and 9%, preferably substantially equal to 2%.

La structure de véranda 1 peut également être adossée à deux façades 80 de bâtiment par exemple (non illustrée). Dans ce cas, une première façade 80 se trouve de préférence au niveau du faîtage de la toiture 4, et une deuxième façade 80 perpendiculaire à la première façade 80 par exemple flanque latéralement la véranda pour former une rive murale.The veranda structure 1 can also be attached to two building facades 80 for example (not shown). In this case, a first facade 80 is preferably located at the level of the ridge of the roof 4, and a second facade 80 perpendicular to the first facade 80 for example flanks the veranda laterally to form a wall edge.

En référence aux figures 2a et 2b présentant deux coupes sur pignon A-A et B-B telles que schématisées sur la figure 1, la toiture 4 est solidaire de la paroi 2 par l'intermédiaire d'une panne sablière 3 et d'un support de toiture 6.With reference to figures 2a And 2b presenting two gable sections AA and BB as shown schematically on the figure 1 , the roof 4 is secured to the wall 2 via a sand pan 3 and a roof support 6.

Selon une possibilité, trois pannes sablières 3 surmontent trois parois 2 de manière à former un encadrement continu sur un périmètre de la véranda.According to one possibility, three sand pans 3 surmount three walls 2 so as to form a continuous frame on a perimeter of the veranda.

Avantageusement, au moins une, de préférence deux pannes sablières 3 prennent appui contre le mur 80 de manière à fermer l'encadrement.Advantageously, at least one, preferably two sand pans 3 are supported against the wall 80 so as to close the frame.

La panne sablière 3 peut être soutenue par un poteau 23 à chacune de ses extrémités.The top plate 3 can be supported by a post 23 at each of its ends.

La panne sablière peut de préférence former un prolongement de la paroi 2 au niveau de la partie supérieure de ladite paroi 2 selon l'axe vertical y.The top plate can preferably form an extension of the wall 2 at the level of the upper part of said wall 2 along the vertical axis y.

La panne sablière peut être formée d'au moins et de préférence d'exactement deux profilés s'étendant dans des plans verticaux parallèles entre eux.The top plate can be formed of at least and preferably of exactly two profiles extending in vertical planes parallel to each other.

Le coefficient de conduction thermique des profilés, de préférence en aluminium, peut être supérieur à 160 W/m.K.The thermal conductivity coefficient of the profiles, preferably aluminum, can be greater than 160 W/m.K.

Les profilés peuvent être reliés entre eux par au moins une barrette, de préférence en polyamide, dont le coefficient de conduction thermique est inférieur à 0.35 W/m.K.The profiles can be connected together by at least one strip, preferably made of polyamide, whose thermal conduction coefficient is less than 0.35 W/m.K.

De préférence, l'au moins une barrette fait office de rupture de pont thermique entre les deux profilés.Preferably, the at least one bar acts as a thermal break between the two profiles.

La toiture 4 peut être de forme sensiblement parallélépipédique. Elle peut présenter une face supérieure 41 et une face inférieure 42, et au moins un flanc latéral 43.The roof 4 can be of substantially parallelepiped shape. It may have an upper face 41 and a lower face 42, and at least one lateral side 43.

Le flanc latéral 43 peut être de préférence sensiblement orthogonal aux faces inférieure et supérieure 42, 41.The lateral side 43 can preferably be substantially orthogonal to the lower and upper faces 42, 41.

La toiture peut présenter de préférence quatre flancs latéraux 43.The roof can preferably have four side walls 43.

Alternativement, pour d'autres formes de toiture 4, la toiture peut présenter un nombre différents de flancs latéraux (un flanc latéral pour une forme ronde par exemple, deux flancs latéraux pour une forme demi-ronde par exemple, ou plus de quatre flancs latéraux pour des formes polyédriques par exemple).Alternatively, for other roof shapes 4, the roof may have a different number of side walls (one side wall for a round shape for example, two side walls for a half-round shape for example, or more than four side walls for polyhedral shapes for example).

Dans la suite, « le » flanc latéral 43 s'entend par « ledit au moins un » flanc latéral 43.In the following, “the” lateral flank 43 is understood as “said at least one” lateral flank 43.

La toiture 4 présente notamment une épaisseur h selon un axe vertical z.The roof 4 has in particular a thickness h along a vertical axis z.

En outre, la toiture 4 peut comprendre au moins un panneau 40 autoportant. Un tel panneau 40 peut comprendre une enveloppe au moins partiellement rigide, en aluminium par exemple, de préférence au niveau des faces supérieures 41 et inférieures 42, et une âme en matériau isolant tel qu'une mousse polyuréthane (PU) par exemple.In addition, the roof 4 may include at least one self-supporting panel 40. Such a panel 40 may comprise an at least partially rigid envelope, made of aluminum for example, preferably at the level of the upper faces 41 and lower faces 42, and a core made of insulating material such as polyurethane foam (PU) for example.

Le panneau 40 peut également être de forme sensiblement parallélépipédique et présente une épaisseur h' selon l'axe vertical z comprise entre 50 mm et 250 mm, de préférence entre 55 mm et 167 mm.The panel 40 can also be of substantially parallelepiped shape and has a thickness h' along the vertical axis z of between 50 mm and 250 mm, preferably between 55 mm and 167 mm.

Ce panneau 40 peut avantageusement comprendre des préformes sur deux tranches ou flancs latéraux opposés de manière à pouvoir assembler plusieurs panneaux 40 entre eux.This panel 40 can advantageously comprise preforms on two opposite edges or side walls so as to be able to assemble several panels 40 together.

Deux panneaux 40 peuvent ainsi être assemblés bord à bord par l'intermédiaire d'au moins une clé de jonction. Un premier flanc latéral d'un premier panneau peut comprendre une ou plusieurs rainures ou mortaises, de préférence deux, aptes à coopérer avec une ou plusieurs clés de jonction, de préférence deux, sous forme de profilés aluminium par exemple. Un deuxième flanc latéral d'un deuxième panneau en regard dudit premier flanc latéral peut également comprendre une ou plusieurs rainures, de préférence deux, aptes à coopérer avec lesdites clés de jonction.Two panels 40 can thus be assembled edge to edge using at least one junction key. A first lateral side of a first panel may comprise one or more grooves or mortises, preferably two, capable of cooperating with one or more junction keys, preferably two, in the form of aluminum profiles for example. A second sidewall of a second panel facing said first sidewall may also comprise one or more grooves, preferably two, capable of cooperating with said junction keys.

Un tel système d'assemblage par clé de jonction permet avantageusement de rigidifier l'ensemble de la toiture 4.Such an assembly system using a junction key advantageously makes it possible to stiffen the entire roof 4.

Alternativement, différents types de jonction peuvent être envisagés entre les panneaux autoportants. Le deuxième flanc latéral peut présenter une forme comprenant un ou plusieurs tenons complémentaire du premier flanc latéral par exemple. Des traverses orthogonales traversant de part en part les flancs latéraux des panneaux 40 peuvent également être envisagées.Alternatively, different types of junction can be considered between the self-supporting panels. The second sidewall may have a shape comprising one or more tenons complementary to the first sidewall by example. Orthogonal crosspieces crossing right through the side walls of the panels 40 can also be considered.

Les flancs latéraux des panneaux 40 peuvent se confondre avec les flancs latéraux 43 de la toiture 4.The side walls of the panels 40 can merge with the side walls 43 of the roof 4.

La toiture 4 peut comprendre au moins un puits de lumière. Le puits de lumière peut comprendre au moins un matériau transparent de sorte à laisser passer la lumière depuis l'extérieur de la véranda jusqu'à l'intérieur de la véranda. Le puits de lumière peut être agencé au travers de l'épaisseur d'au moins un panneau autoportant 40.The roof 4 may include at least one skylight. The skylight may include at least one transparent material so as to allow light to pass from outside the veranda to the interior of the veranda. The skylight can be arranged through the thickness of at least one self-supporting panel 40.

La toiture 4 comprend en outre une membrane 9 étanche au niveau de la face supérieure 41. Cette membrane 9 peut être avantageusement et de préférence monobloc, de sorte à assurer une étanchéité parfaite au niveau de la face supérieure 41 de la toiture 4.The roof 4 further comprises a waterproof membrane 9 at the level of the upper face 41. This membrane 9 can advantageously and preferably be in one piece, so as to ensure perfect sealing at the level of the upper face 41 of the roof 4.

En particulier, une telle membrane 9 peut être réalisée sur mesure en usine aux dimensions voulues avant une pose par collage sur site.In particular, such a membrane 9 can be made to measure in the factory to the desired dimensions before installation by gluing on site.

Alternativement, la membrane 9 peut comprendre plusieurs lais soudés ou raccordés entre eux.Alternatively, the membrane 9 may comprise several strips welded or connected together.

La membrane 9 peut être en élastomère, de préférence en caoutchouc EPDM (éthylène-propylène-diène monomère) et présenter une épaisseur h" comprise entre 1 mm et 5 mm, de préférence entre 1,5mm et 3 mm.The membrane 9 may be made of elastomer, preferably of EPDM rubber (ethylene-propylene-diene monomer) and have a thickness h" of between 1 mm and 5 mm, preferably between 1.5 mm and 3 mm.

L'épaisseur h de la toiture 4 peut dès lors être définie par : h = h' + h"The thickness h of the roof 4 can therefore be defined by: h = h' + h"

La toiture 4, et de préférence la face inférieure 42 de la toiture 4, est avantageusement en appui sur au moins un support 6 de toiture.The roof 4, and preferably the lower face 42 of the roof 4, advantageously rests on at least one roof support 6.

La toiture 4 est de préférence uniquement en appui sur le support 6.The roof 4 is preferably only supported on the support 6.

La figure 4 illustre en vue de dessus la coopération entre la toiture 4 et les supports 6.There Figure 4 illustrates in top view the cooperation between the roof 4 and the supports 6.

Lesdits supports 6 peuvent être assemblés de manière à former de préférence un périmètre fermé dans l'espace intérieur de la véranda.Said supports 6 can be assembled so as to preferably form a closed perimeter in the interior space of the veranda.

Les flancs latéraux 43 de la toiture 4 sont avantageusement libres de tout contact avec les pannes sablières 3 et/ou les façades 80.The side walls 43 of the roof 4 are advantageously free from any contact with the sand pans 3 and/or the facades 80.

Avantageusement, la toiture 4 ne prend pas appui sur une extrémité supérieure 33 de la sablière 3.Advantageously, the roof 4 does not rest on an upper end 33 of the sand pit 3.

Le support 6 peut être fixé sur une face interne 32 de la panne sablière 3, de sorte qu'une surface d'appui offerte à la toiture 4 par le support 6 soit située à une distance d de l'extrémité supérieure 33 de ladite panne sablière 3.The support 6 can be fixed on an internal face 32 of the sand pan 3, so that a support surface offered to the roof 4 by the support 6 is located at a distance d from the upper end 33 of said purlin. sand pit 3.

La distance d peut être telle que : 20 mm < d < h.The distance d can be such that: 20 mm < d < h.

Au niveau de l'égout de toiture en particulier, la distance d peut être comprise entre : h - 10 mm < d < h.At the roof drain in particular, the distance d can be between: h - 10 mm < d < h.

De manière avantageuse, la toiture 4 est donc au moins partiellement encastrée selon l'axe z, dans un espace délimité par les faces internes 32 des pannes sablières 3.Advantageously, the roof 4 is therefore at least partially embedded along the z axis, in a space delimited by the internal faces 32 of the sand pans 3.

La toiture 4 présente dès lors un recouvrement vertical entre son flanc latéral 43 et la face interne 32 de la panne sablière 3 en regard dudit flanc latéral 43.The roof 4 therefore has a vertical overlap between its lateral side 43 and the internal face 32 of the top plate 3 facing said lateral side 43.

De préférence, le flanc latéral 43 n'est pas en contact avec la face interne 32. Une distance de calage de l'ordre de 10 à 20 mm entre le flanc 43 et la face interne 32 peut avantageusement permettre une dilatation des panneaux 40 selon les axes x et/ou y.Preferably, the lateral sidewall 43 is not in contact with the internal face 32. A wedging distance of the order of 10 to 20 mm between the sidewall 43 and the internal face 32 can advantageously allow expansion of the panels 40 according to the x and/or y axes.

Un joint tubulaire, également dénommé fond de joint, de diamètre sensiblement égal à 20 mm peut avantageusement être logé dans cet espace de calage de manière à limiter les effets de condensation.A tubular joint, also called joint base, with a diameter substantially equal to 20 mm can advantageously be housed in this wedging space so as to limit the effects of condensation.

Le support de toiture 6 peut avoir une forme générale de cornière. Une première aile 61 dudit support 6 sur laquelle s'appuie la toiture 4 peut s'étendre depuis, et sensiblement perpendiculairement à, la face interne 32 de la panne sablière 3, sur une distance comprise entre 40 mm et 100 mm. Une deuxième aile 62 du support 6 solidaire de la face interne 32 peut présenter une hauteur selon un axe vertical z comprise entre 40 mm et 100 mm.The roof support 6 may have the general shape of an angle. A first wing 61 of said support 6 on which the roof 4 rests can extend from, and substantially perpendicular to, the internal face 32 of the top plate 3, over a distance of between 40 mm and 100 mm. A second wing 62 of the support 6 secured to the internal face 32 may have a height along a vertical axis z of between 40 mm and 100 mm.

Le support de toiture 6 peut être de préférence continu sous forme de profilé sur toute une longueur de la panne sablière 3. Alternativement, il peut être discontinu et/ou ne présenter qu'un nombre fini de points d'appui pour la toiture 4.The roof support 6 may preferably be continuous in the form of a profile over an entire length of the top plate 3. Alternatively, it may be discontinuous and/or present only a finite number of support points for the roof 4.

Les supports de toiture 6 latéraux, au niveau des pignons, s'étendant principalement selon un axe y, sont fixés sur les faces internes 32 des pannes sablières 3 latérales correspondantes de manière à présenter l'inclinaison souhaitée de la toiture vis-à-vis d'un plan horizontal. La distance d varie dans ce cas entre une valeur minimale pour une extrémité du support de toiture 6 latéral au niveau de la façade 80 du bâtiment et une valeur maximale pour une extrémité opposée dudit support 6, au niveau de l'égout.The 6 lateral roof supports, at the level of the gables, extending mainly along an axis y, are fixed on the internal faces 32 of the corresponding 3 lateral sanding purlins so as to present the desired inclination of the roof vis-à-vis of a horizontal plane. The distance d varies in this case between a minimum value for one end of the lateral roof support 6 at the level of the facade 80 of the building and a maximum value for an opposite end of said support 6, at the level of the sewer.

Les supports de toiture 6 peuvent également comprendre avantageusement des profilés d'étanchéité 63, également dénommés profils d'étanchéité, en EPDM par exemple, de sorte à assurer une liaison étanche entre la toiture 4 et les supports de toiture 6.The roof supports 6 can also advantageously comprise sealing profiles 63, also called sealing profiles, in EPDM for example, so as to ensure a watertight connection between the roof 4 and the roof supports 6.

Au moins un support de toiture 6 est solidaire d'au moins un mur de façade 80 sur lequel est adossée la véranda.At least one roof support 6 is integral with at least one facade wall 80 against which the veranda is backed.

La structure de véranda 1 comprend en outre le bandeau 5 combinant des fonctions techniques et esthétiques.The veranda structure 1 further comprises the strip 5 combining technical and aesthetic functions.

Le bandeau 5 notamment est configuré de sorte que la toiture 4 soit avantageusement masquée à la vue d'un observateur extérieur à la véranda situé au niveau du sol.The strip 5 in particular is configured so that the roof 4 is advantageously hidden from view of an observer outside the veranda located at ground level.

Le bandeau 5 présente notamment un bord supérieur 50 tel que la face supérieure 41 de la toiture 4 est située sous un plan horizontal passant par ledit bord supérieur 50. De manière avantageuse, la toiture 4 peut ainsi être totalement occultée par le bandeau 5.The strip 5 has in particular an upper edge 50 such that the upper face 41 of the roof 4 is located under a horizontal plane passing through said upper edge 50. Advantageously, the roof 4 can thus be completely obscured by the strip 5.

Le bandeau 5 comprend notamment un chéneau 51.The strip 5 notably includes a gutter 51.

Ce chéneau 51 comprend au moins un fond 510, un bord intérieur 511 et un bord extérieur 512. Une largeur L du chéneau 51, définie par la distance entre les deux bords intérieurs et extérieur 511, 512 peut être comprise entre 10 cm et 30 cm, de préférence entre 13 cm et 25 cm.This gutter 51 comprises at least one bottom 510, an interior edge 511 and an exterior edge 512. A width L of the gutter 51, defined by the distance between the two interior and exterior edges 511, 512 can be between 10 cm and 30 cm , preferably between 13 cm and 25 cm.

Le chéneau 51 est fixé de préférence par son bord intérieur 511 à la face externe 31 de la panne sablière 3.The gutter 51 is preferably fixed by its interior edge 511 to the exterior face 31 of the top plate 3.

Le chéneau 51 peut coopérer avec au moins une colonne de descente de manière à évacuer les eaux de pluie.The gutter 51 can cooperate with at least one downspout column so as to evacuate rainwater.

Par ailleurs, les panneaux 40 de toiture 4 étant au moins partiellement circonscrits à l'espace intérieur de la véranda délimité par les faces internes 32 des sablières 3, un débord 7 est avantageusement fixé dans le prolongement de la face supérieure 41 de la toiture 4 de manière à guider un écoulement d'eaux de pluie dans le chéneau 51.Furthermore, the roof panels 40 4 being at least partially circumscribed to the interior space of the veranda delimited by the internal faces 32 of the sand pits 3, an overhang 7 is advantageously fixed in the extension of the upper face 41 of the roof 4 so as to guide a flow of rainwater into the gutter 51.

Le débord 7 peut donc se prolonger depuis les panneaux 40 par-dessus l'extrémité supérieure 33 et au-delà de la face externe 31 de la panne sablière 3, au moins jusqu'au droit du premier bord intérieur 511 du chéneau 51, de préférence au droit du fond 510 du chéneau 51.The overhang 7 can therefore extend from the panels 40 over the upper end 33 and beyond the external face 31 of the top plate 3, at least to the right of the first interior edge 511 of the gutter 51, from preferably to the right of the bottom 510 of the gutter 51.

Le débord 7 peut être un profilé aluminium avantageusement de faible épaisseur présentant un profilé de retombée, également dénommé profil de retombée, sensiblement vertical au-dessus du chéneau 51. Un tel profilé de retombée peut être obtenu simplement par pliage par exemple.The overhang 7 can be an advantageously thin aluminum profile having a drop-out profile, also called a drop-out profile, substantially vertical above the gutter 51. Such a drop-out profile can be obtained simply by folding for example.

La largeur totale du débord 7 peut être comprise entre 120 mm et 280 mm.The total width of the overhang 7 can be between 120 mm and 280 mm.

En particulier, le débord 7 peut s'étendre depuis un plan vertical en prolongement de la face interne 32 de la sablière 3 jusqu'au profilé de retombé à l'aplomb du chéneau sur une largeur comprise entre 80 et 200 mm.In particular, the overhang 7 can extend from a vertical plane as an extension of the internal face 32 of the top plate 3 to the falling profile directly above the gutter over a width of between 80 and 200 mm.

Le débord 7 peut recouvrir solidairement le panneau 40 au niveau de la face supérieure 42 de la toiture sur une largeur comprise entre 30 et 60 mm.The overhang 7 can integrally cover the panel 40 at the level of the upper face 42 of the roof over a width of between 30 and 60 mm.

Le débord 7 peut également comprendre au moins une ailette de calage sur une face inférieure du débord, ladite ailette pouvant venir s'appuyer contre le flanc latéral 43 par exemple afin de positionner précisément le débord 7 au niveau d'un pourtour de la toiture 4.The overhang 7 can also include at least one wedging fin on a lower face of the overhang, said fin being able to rest against the lateral side 43 for example in order to precisely position the overhang 7 at the level of a periphery of the roof 4 .

Un joint souple 751 peut avantageusement relier le débord 7, de préférence au niveau du profil de retombée, au bord intérieur 511 du chéneau 51 ou à la face externe 31 de la panne sablière 3.A flexible joint 751 can advantageously connect the overhang 7, preferably at the level of the fallout profile, to the interior edge 511 of the gutter 51 or to the external face 31 of the top plate 3.

Le joint 751 peut être configuré pour accommoder une différence de niveau entre le débord 7 de la toiture 4 et le chéneau 51, selon l'inclinaison de la toiture 4. Il peut par exemple présenter une forme en soufflet.The joint 751 can be configured to accommodate a difference in level between the overhang 7 of the roof 4 and the gutter 51, depending on the inclination of the roof 4. It can for example have a bellows shape.

Avantageusement, ce joint 751 peut être emboîté dans des rainures respectives du profilé de retombée et du bord intérieur de chéneau.Advantageously, this joint 751 can be fitted into respective grooves of the dropout profile and the interior edge of the gutter.

Ce joint 751 peut être en EPDM par exemple.This seal 751 can be made of EPDM for example.

Par construction et tel que décrit précédemment, la distance d est maximale en bas de pente au niveau de l'égout de toiture tel qu'illustré à la figure 3b. Pour éviter que le débord 7 soit en contact direct avec l'extrémité supérieure 33 de la panne sablière 3 dans le cas où d est sensiblement égale à la valeur maximale, un joint compensateur 330 en EPDM par exemple peut être ajouté au niveau de ladite extrémité supérieure 33.By construction and as described previously, the distance d is maximum at the bottom of the slope at the level of the roof drain as illustrated in figure 3b . To prevent the overhang 7 from being in direct contact with the upper end 33 of the top plate 3 in the case where d is substantially equal to the maximum value, a compensating seal 330 in EPDM for example can be added at said end upper 33.

Avantageusement, la membrane 9 peut se prolonger de manière à recouvrir le débord 7 de la face supérieure 41, et le profilé de retombée. La structure de véranda 1 peut ainsi présenter une étanchéité continue entre la face supérieure 41 prolongée par le débord 7 et le profilé de retombée, et le joint 751 fixé au chéneau 51 ou à la face externe 31 de la panne sablière 3.Advantageously, the membrane 9 can extend so as to cover the overhang 7 of the upper face 41, and the fallout profile. The veranda structure 1 can thus present a continuous seal between the upper face 41 extended by the overhang 7 and the fallout profile, and the seal 751 fixed to the gutter 51 or to the external face 31 of the sand pan 3.

Le bandeau 5 peut également comprendre un profilé de réhausse 52 solidaire du bord extérieur 512 du chéneau 51. Ce profilé de réhausse 52 peut prolonger en partie verticalement le bord extérieur 512.The strip 5 can also include an extension profile 52 secured to the outer edge 512 of the gutter 51. This extension profile 52 can partially extend the outer edge 512 vertically.

Côté extérieur, il peut être stylisé afin de contribuer à l'esthétique de la structure de véranda 1.On the exterior side, it can be stylized to contribute to the aesthetics of the veranda structure 1.

Optionnellement le bandeau 5 peut également comprendre un coffre 53 pour volet roulant. Ce coffre 53 peut avantageusement être fixé sous le chéneau 51, dans un prolongement du bord extérieur 512 et/ou du profilé de réhausse 52. Le fond 510 du chéneau 51 peut notamment constituer un capot supérieur pour ledit coffre 53. La largeur du coffre 53 peut être sensiblement égale à la largeur L du chéneau 51.Optionally, the strip 5 can also include a box 53 for rolling shutter. This box 53 can advantageously be fixed under the gutter 51, in an extension of the outer edge 512 and/or of the raising profile 52. The bottom 510 of the gutter 51 can in particular constitute an upper cover for said trunk 53. The width of the trunk 53 can be substantially equal to the width L of the gutter 51.

En référence à la figure 3a, une cornière de maintien 8 au niveau du faîtage de toiture 4 peut avantageusement faire jonction entre la face supérieure 41 de la toiture 4 et la façade 80 du bâtiment. La cornière de maintien 8 peut présenter des dimensions transverses comprises entre 40 mm et 100 mm.In reference to the figure 3a , a retaining angle 8 at the level of the roof ridge 4 can advantageously make a connection between the upper face 41 of the roof 4 and the facade 80 of the building. The retaining angle 8 can have transverse dimensions of between 40 mm and 100 mm.

De préférence, le flanc latéral 43 de la toiture 4 n'est pas en contact de la façade 80. Une distance de calage de l'ordre de 10 à 20 mm entre le flanc 43 et la façade 80 peut avantageusement permettre une dilatation des panneaux 40 selon l'axe y, et une adaptation aux irrégularités du mur 80 par exemple.Preferably, the lateral side 43 of the roof 4 is not in contact with the facade 80. A wedging distance of around 10 to 20 mm between the side 43 and the facade 80 can advantageously allow expansion of the panels 40 along the y axis, and adaptation to the irregularities of the wall 80 for example.

Un joint tubulaire ou fond de joint d'un diamètre de l'ordre de 30 mm peut également être logé dans cet espace de calage.A tubular joint or joint base with a diameter of around 30 mm can also be accommodated in this wedging space.

Avantageusement, la membrane 9 peut se prolonger de manière à recouvrir la cornière 8. La membrane 9 peut ainsi être relevée contre la façade 80, sur une hauteur comprise entre 40 mm et 150 mm afin d'assurer une bonne étanchéité au niveau du faîtage.Advantageously, the membrane 9 can extend so as to cover the angle iron 8. The membrane 9 can thus be raised against the facade 80, to a height of between 40 mm and 150 mm in order to ensure good sealing at the level of the ridge.

L'ensemble de la cornière 8 et d'une partie de la membrane 9 recouvrant la cornière 8 et relevée contre la façade 80 peut former un raccord d'étanchéité entre la toiture 4 et la façade de bâtiment 80.The whole of the angle 8 and part of the membrane 9 covering the angle 8 and raised against the facade 80 can form a sealing connection between the roof 4 and the building facade 80.

Une lame 81 et une casquette 82 peuvent également compléter la structure de véranda 1 au niveau du faîtage.A blade 81 and a cap 82 can also complete the veranda structure 1 at the ridge level.

La lame 81 peut notamment permettre un maintien mécanique de la membrane 9 contre la cornière 8 et/ou contre la façade 80.The blade 81 can in particular allow mechanical retention of the membrane 9 against the angle 8 and/or against the facade 80.

La casquette 82 peut avantageusement protéger le raccord d'étanchéité contre les intempéries et déporter un ruissellement d'eaux de pluie de manière à améliorer l'étanchéité au niveau du faîtage.The cap 82 can advantageously protect the sealing connection against bad weather and deport a runoff of rainwater so as to improve the seal at the level of the ridge.

Un autre aspect concerne un procédé de montage d'une structure de véranda 1 telle que décrite ci-dessus.Another aspect relates to a method of mounting a veranda structure 1 as described above.

La véranda présente une dimension en profondeur p selon l'axe y, une hauteur de paroi 2 (au niveau du bas de la sablière 3) Hparoi, une hauteur de sablière 3 Hsablière, et une pente de toiture 4 dénommée pente. Le support 6 présente une épaisseur selon z Esupport. The veranda has a depth dimension p along the y axis, a wall height 2 (at the level of the bottom of the plate 3) H wall , a plate height 3 H plate , and a roof slope 4 called slope. The support 6 has a thickness according to z E support.

  • Fixer horizontalement le support 6 sur le mur de façade, chacune de ses extrémités étant en butée contre les sablières 3 des parois 2 latérales. Le support 6 est fixé à une hauteur Hfaîtage telle que : Hfaîtage = Hparoi + Hsablière - d - Esupport + (p X tan pente) exprimée en mm.
  • Fixer horizontalement le support 6 sur la face interne 32 de la sablière 3 située à l'avant de la véranda, chacune des extrémités du support étant en butée contre les sablières 3 latérales. Le support 6 est fixé à une hauteur Hfront telle que : Hfront = Hparoi + Hsablière - d - Esupport exprimée en mm.
  • Fixer les supports 6 latéralement sur les faces internes 32 des sablières 3 latérales, chacune de leurs extrémités étant en butée contre les supports déjà mis en place sur le mur et à l'avant de la véranda. Les supports 6 latéraux présentent de cette manière une pente égale à la pente de toiture.
  • Déposer l'une des sablières 3 latérales de manière à pouvoir glisser les panneaux 40 autoportants.
  • Mettre en place le premier panneau 40 en prévoyant environ 15 mm de calage vis-à-vis des faces internes 32 des pannes sablières 3.
  • Assembler les clés de jonction inférieure et supérieure dans les rainurages prévus dans la tranche du panneau 40.
  • Fixer au moins la clé de jonction inférieure au niveau de ses extrémités, coté mur et côté opposé sur la sablière 3 à l'avant de la véranda, par des équerres de fixation par exemple.
  • Mettre en place les autres panneaux 40 par glissement, jusqu'au dernier, en les assemblant respectivement entre eux par des clés de jonction.
  • Replacer la sablière 3 latérale et le bandeau 5 correspondant.

  • Mettre en place et fixer la cornière de maintien 8 au niveau du faîtage pour assurer la jonction entre le mur 80 et la face supérieure 41 de la toiture 4. La cornière déborde de 115 mm environ de part et d'autre de la toiture 4 de manière à pouvoir fixer ultérieurement le débord 7.
  • Clipper le joint compensateur 330 au niveau de l'extrémité supérieure de la sablière 3 à l'avant de la véranda, et sur 10 cm environ sur les extrémités supérieures des sablières 3 latérales à partir de la sablière 3 avant.
  • Clipper un bord du joint 751 sur le débord 7.
  • Clipper un bord opposé audit bord du joint sur le bord intérieur 511 du chéneau 51.
  • Positionner le débord 7 en prolongement de la face supérieure 41 de la toiture 4 en calant l'ailette de calage du débord 7 contre les flancs latéraux 43 de la toiture 4.
  • Fixer le débord 7 sur la cornière de maintien 8.
  • Fixer le débord 7 sur la face supérieure 41 de la toiture, par des rivets par exemple.
  • Positionner et coller la membrane d'étanchéité 9 de manière à couvrir la face supérieure 41 de la toiture 4, le débord 7 et la cornière de maintien 8.
The assembly process comprises at least the following steps:
  • Position opposite the facade wall 80 and fix all the walls 2, frames 22, posts 23, top plates 3 and gutters 51.
  • Fix the support 6 horizontally on the front wall, each of its ends abutting against the plates 3 of the side walls 2. The support 6 is fixed at a height H ridge such that: H ridge = H wall + H plate - d - E support + (p X tan slope ) expressed in mm.
  • Horizontally fix the support 6 on the internal face 32 of the top plate 3 located at the front of the veranda, each end of the support abutting against the side plates 3. The support 6 is fixed at a height H front such that: H front = H wall + H plate - d - E support expressed in mm.
  • Fix the supports 6 laterally on the internal faces 32 of the side plates 3, each of their ends abutting against the supports already placed on the wall and at the front of the veranda. The side supports 6 thus have a slope equal to the roof slope.
  • Remove one of the side plates 3 so that you can slide the self-supporting panels 40.
  • Place the first panel 40, allowing approximately 15 mm of wedging with respect to the internal faces 32 of the sanding purlins 3.
  • Assemble the lower and upper junction keys in the grooves provided in the edge of panel 40.
  • Fix at least the lower junction key at the level of its ends, on the wall side and the opposite side on the top plate 3 at the front of the veranda, using fixing brackets for example.

  • Replace the side plate 3 and the corresponding strip 5.
  • Place a joint filler in the space between the side walls 43 of the roof 4 and the internal faces 32 and the wall 80.
  • Place and fix the retaining angle 8 at the level of the ridge to ensure the junction between the wall 80 and the upper face 41 of the roof 4. The angle extends by approximately 115 mm on either side of the roof 4 of so that the overhang 7 can be fixed later.
  • Clip the compensating joint 330 at the upper end of the top plate 3 at the front of the veranda, and approximately 10 cm on the upper ends of the side plates 3 from the front plate 3.
  • Clip one edge of joint 751 onto overhang 7.
  • Clip an edge opposite said edge of the joint onto the interior edge 511 of the gutter 51.
  • Position the overhang 7 as an extension of the upper face 41 of the roof 4 by wedging the wedging fin of the overhang 7 against the side walls 43 of the roof 4.
  • Fix the overhang 7 on the retaining angle 8.
  • Fix the overhang 7 on the upper face 41 of the roof, using rivets for example.
  • Position and glue the waterproofing membrane 9 so as to cover the upper face 41 of the roof 4, the overhang 7 and the retaining angle 8.
