Description

La présente invention est relative à un procédé de pose sur des éléments parallèles de la charpente d'un bâtiment, d'une couverture comprenant des tôles d'acier nervuré, une couche isolante, notamment formée de plaques adjacentes, disposée sur ces tôles, et un revêtement d'étanchéité recouvrant la couche isolante.The present invention relates to a method of laying on parallel elements of the frame of a building, a cover comprising ribbed steel sheets, an insulating layer, in particular formed by adjacent plates, placed on these sheets, and a sealing coating covering the insulating layer.

La technique classique de pose des couvertures de ce type décrite dans le D.T.U. 43.3 (normes françaises) est la suivante :

  • on fixe les tôles d'acier nervuré sur les éléments (généralement les pannes) de la charpente, au droit des creux d'onde;
  • on fixe les plaques isolantes sur les tôles d'acier nervuré par des vis ou analogues, c'est-à-dire des vis, des rivets ou des goujons, dont la tête s'appuie sur une rondelle rigide. Ces vis se vissent dans les tôles d'acier nervuré;
  • enfin, le revêtement d'étanchéité est rendu solidaire des plaques d'isolation par collage ou par soudage à l'aide d'une source chaude, le plus souvent par un chalumeau à flamme ou à air, sur toute la surface des panneaux isolants et éventuellement au droit des rondelles des vis. En variante, le revêtement peut être fixé par des vis de la même manière que les plaques isolantes.
The classic technique for installing covers of this type described in DTU 43.3 (French standards) is as follows:
  • the ribbed steel sheets are fixed on the elements (generally the purlins) of the frame, in line with the troughs;
  • the insulating plates are fixed to the ribbed steel sheets by screws or the like, that is to say screws, rivets or studs, the head of which rests on a rigid washer. These screws are screwed into ribbed steel sheets;
  • finally, the waterproofing coating is made integral with the insulation plates by bonding or by welding using a hot source, most often by a flame or air torch, over the entire surface of the insulating panels and possibly in line with the screw washers. Alternatively, the covering can be fixed by screws in the same way as the insulating plates.

Le vent crée d'importants efforts de compression et de dépression, par emplacements, sur la couverture (tourbillons, effet de masque derrière une paroi ou une émergence de la toiture). Les efforts sont exercés sur la surface extérieure, donc sur le revêtement d'étanchéité, qui sollicite in fine l'élément porteur et la structure du bâtiment.The wind creates significant compression and depression forces, in places, on the cover (swirls, mask effect behind a wall or an emergence of the roof). The forces are exerted on the exterior surface, therefore on the waterproofing coating, which ultimately stresses the load-bearing element and the structure of the building.

Dans le but de résister aux forces de dépression créées par le vent, les normes françaises définies dans le cadre du D.T.U. 43.3 et les usages prévoient un minimum de cinq fixations par m2 de toiture, partant du fait qu'une vis de fixation résiste à environ 900N à l'arrachement.In order to resist the forces of depression created by the wind, the French standards defined within the framework of DTU 43.3 and uses provide for a minimum of five fastenings per m 2 of roof, starting from the fact that a fastening screw resists about 900N at breakout.

La rupture se situe au niveau du plan de collage du revêtement d'étanchéité sur la rondelle, ou par déboutonnage de la tête de fixation au travers de la rondelle, ou par arrachement de la fixation au travers de la tôle d'acier nervuré. Les valeurs de rupture sont relativement homogènes, de l'ordre de 900 à 1300 N.The rupture is located at the level of the bonding plane of the sealing coating on the washer, or by unbuttoning the fixing head through the washer, or by tearing off the fixing through the ribbed steel sheet. The breaking values are relatively homogeneous, of the order of 900 to 1300 N.

Dans cette technique classique, le grand nombre de fixations qui est nécessaire rend la mise en oeuvre longue et coûteuse. De plus, toutes les fixations apparaissent en sous-face des tôles d'acier nervuré, ce qui est gênant du point de vue esthétique.In this classic technique, the large number of fasteners which is necessary makes the implementation long and expensive. In addition, all the fasteners appear on the underside of the ribbed steel sheets, which is awkward from an aesthetic point of view.

L'invention a pour but de fournir une couverture du même type qui soit beaucoup plus rapide et économique à mettre en oeuvre et qui ne laisse pratiquement pas apparaître de vis ou analogues en sous-face.The object of the invention is to provide a cover of the same type which is much faster and economical to implement and which practically does not allow the appearance of screws or the like on the underside.

A cet effet, l'invention a pour objet, suivant un premier mode de mise en oeuvre, un procédé tel que décrit dans la revendication 1.To this end, the subject of the invention is, according to a first embodiment, a method as described in claim 1.

Suivant un deuxième mode de mise en oeuvre, l'invention a pour objet le procédé décrit dans la revendication 2.According to a second mode of implementation, the subject of the invention is the method described in claim 2.

L'invention a encore pour objet une couverture étanche de bâtiment, notamment pour bâtiment industriel, qui, suivant un premier mode de réalisation, est conforme à la revendication 3, et dont des caractéristiques optionnelles sont décrites dans les revendications 4 et 5.The subject of the invention is also a waterproof building cover, in particular for an industrial building, which, according to a first embodiment, is in accordance with claim 3, and whose optional characteristics are described in claims 4 and 5.

La couverture étanche de bâtiment de l'invention, suivant un deuxième mode de réalisation, est conforme à la revendication 6 et peut comporter la caractéristique de la revendication 7.The waterproof building cover of the invention, according to a second embodiment, is in accordance with claim 6 and may include the characteristic of claim 7.

D'autres caractéristiques de la couverture étanche de bâtiment de l'invention sont décrites dans les revendications 8 à 11.Other characteristics of the waterproof building cover of the invention are described in claims 8 to 11.

Le US-A-4 382 353 décrit une couverture étanche de bâtiment conforme au préambule de la revendication 3 et à celui de la revendication 6. Cependant, dans ce document, les bandes souples sont nécessairement disposées à l'aplomb des joints entre les plaques isolantes et dirigées suivant des lignes de pente de la couverture, c'est-à-dire perpendiculairement aux éléments de charpente.US-A-4 382 353 describes a waterproof building cover in accordance with the preamble of claim 3 and that of claim 6. However, in this document, the flexible strips are necessarily arranged directly above the joints between the plates insulating and directed along the slope lines of the roof, that is to say perpendicular to the structural members.

De plus, dans le même document, pour la même raison, la progression du chantier s'effectue parallèlement aux éléments de charpente, en fixant chaque bande souple sur toute sa longueur avant de passer à la bande souple suivante.In addition, in the same document, for the same reason, the progress of the site is carried out parallel to the structural elements, by fixing each flexible strip over its entire length before moving on to the next flexible strip.

Le EP-A-0 442 805 décrit une couverture étanche de bâtiment dans laquelle chaque organe de fixation est en deux moitiés. Pour la pose de cette couverture, dans un premier temps, on fixe les tôles d'acier nervuré sur les pannes de la charpente au moyen de premiers demi-organes de fixation. Puis les plaques isolantes sont empalées sur l'ensemble de ces premiers demi-organes. Puis les seconds demi-organes de fixation 8 sont mis en place sur les premiers demi-organes, avec interposition des organes de liaison du revêtement et des organes d'appui rigides. Enfin, le revêtement d'étanchéité est déroulé et fixé par soudage ou collage sur les organes de liaison et éventuellement sur les organes d'appui.EP-A-0 442 805 describes a cover watertight building in which each fixing member is in two halves. For the installation of this cover, firstly, the ribbed steel sheets are fixed to the purlins of the frame by means of first half-fixing members. Then the insulating plates are impaled on all of these first half-organs. Then the second fixing half-members 8 are put in place on the first half-members, with interposition of the covering connection members and rigid support members. Finally, the sealing coating is unwound and fixed by welding or gluing on the connecting members and possibly on the support members.

Dans le DE-A-31 26 107, les organes de fixation des plaques isolantes sont mis en place le long des joints de recouvrement du revêtement d'étanchéité, et donc suivant des rangées perpendiculaires aux pannes de la charpente, comme dans le US-A-4 382 353 précité.In DE-A-31 26 107, the fastening members of the insulating plates are placed along the overlapping joints of the waterproofing coating, and therefore in rows perpendicular to the purlins of the frame, as in the US- A-4 382 353 cited above.

Examples of embodiments of the invention will now be described with reference to the appended drawings, in which:
  • Figure 1 is a perspective view of a waterproof cover, during installation, according to two alternative embodiments;
  • Figures 2 and 3 are sectional views taken along a breakdown of the frame, respectively along lines II-II and III-III of Figure 1, of the complete cover;

  • Figure 9 is a longitudinal sectional view of an accessory usable in the mode of realization of Figure 8.

La couverture de bâtiment représentée sans son revêtement d'étanchéité à la Figure 1 est posée sur une série de pannes de charpentes parallèles 1 constituées de fers en I à âme verticale. Elle est constituée de tôles d'acier nervuré 2 dont les ondes sont perpendiculaires aux pannes, de plaques thermiquement isolantes 3 rectangulaires, plus ou moins compressibles, disposés de façon jointive, d'organes 4 de liaison de revêtement, d'organes d'appui 5, et de vis de fixation 6.The building cover shown without its waterproof coating in Figure 1 is placed on a series of purlins of parallel frames 1 made of I-irons with vertical core. It is made up of ribbed steel sheets 2 whose waves are perpendicular to the purlins, thermally insulating plates 3 rectangular, more or less compressible, arranged contiguously, members 4 for covering the covering, support members 5, and fixing screws 6.

Les tôles d'acier nervuré 2 définissent des plages surélevées 7 de relativement grande largeur et des creux d'onde 8 beaucoup plus étroits à flancs 9 fortement inclinés et à fond 10 parallèle aux plages 7.The ribbed steel sheets 2 define raised areas 7 of relatively large width and much narrower wave hollows 8 with flanks 9 which are strongly inclined and at the bottom 10 parallel to the areas 7.

Les organes de liaison 4 sont relativement souples et présentent, au moins sur leur surface supérieure, une matière compatible avec celle du revêtement d'étanchéité en vue du collage ou du soudage de celui-ci. Il peut s'agir d'une bande, continue ou constituée de tronçons successifs, ou de plaquettes, comme illustré respectivement dans la partie droite et dans la partie gauche de la Figure 1, en métal de faible épaisseur revêtu d'une matière appropriée ou constituées du même matériau que le revêtement d'étanchéité et pourvues d'une armature résistant à la déchirure et à la traction. La largeur de cette bande, ou la dimension des plaquettes, peut être de l'ordre de 0,15 à 0,20 m.The connecting members 4 are relatively flexible and have, at least on their upper surface, a material compatible with that of the sealing coating with a view to bonding or welding it. It may be a strip, continuous or consisting of successive sections, or plates, as illustrated respectively in the right part and in the left part of FIG. 1, of thin metal coated with an appropriate material or made of the same material as the waterproofing coating and provided with a tear and tensile resistant frame. The width of this strip, or the size of the plates, can be of the order of 0.15 to 0.20 m.

Les organes d'appui 5 sont des organes rigides, notamment en tôle d'acier d'au moins 1 mm d'épaisseur protégée contre la corrosion, par exemple par galvanisation. Il peut s'agir d'une succession de feuillards de forme allongée ou de rondelles, comme illustré respectivement dans la partie droite et dans la partie gauche de la Figure 1. Le diamètre des rondelles peut être de l'ordre de 60 mm et la largeur des feuillards de l'ordre de 40 mm. Ces dimensions sont de toute manière nettement inférieures à la largeur de la bande souple 4 ou à la dimension des plaquettes souples 4. - Comme on le voit sur les Figures 2, 3 et 5, chaque rondelle peut présenter une cuvette emboutie 11 ayant à peu près la même hauteur que les têtes 12 des vis 6, et chaque feuillard peut présenter deux nervures longitudinales 11 ayant une hauteur du même ordre.The support members 5 are rigid members, in particular made of sheet steel at least 1 mm thick, protected against corrosion, for example by galvanization. It may be a succession of strips of elongated shape or washers, as illustrated respectively in the right part and in the left part of Figure 1. The diameter of the washers can be of the order of 60 mm and the strip width of the order of 40 mm. These dimensions are in any case significantly smaller than the width of the flexible strip 4 or the dimension of the flexible plates 4. - As can be seen in Figures 2, 3 and 5, each washer can have a deep-drawn bowl 11 having little near the same height as the heads 12 of the screws 6, and each strip can have two longitudinal ribs 11 having a height of the same order.

Les vis 6 ont une longueur supérieure à la somme de l'épaisseur des ailes 13 des pannes, de la hauteur des tôles d'acier nervuré 2 et de l'épaisseur des plaques 3. Elles présentent, à partir de leur tête 12, une partie lisse 14 dont la longueur est supérieure à la somme des épaisseurs des plaques 3 et de la tôle 2, puis une partie filetée 15 et une pointe 16 autotaraudeuse ou autoforeuse-taraudeuse. En variante, les vis 6 pourraient être filetées sur toute leur hauteur.The screws 6 have a length greater than the sum of the thickness of the wings 13 of the purlins, the height of the ribbed steel sheets 2 and the thickness of the plates 3. They have, from their head 12, a smooth part 14, the length of which is greater than the sum of the thicknesses of the plates 3 and of the sheet metal 2, then a threaded part 15 and a self-tapping or self-tapping-tapping point 16. Alternatively, the screws 6 could be threaded over their entire height.

La pose de cette couverture s'effectue de la manière suivante.

  • (a) On met en place sur les pannes les tôles d'acier nervuré 2 et, si nécessaire, on assure leur fixation provisoire sur ces pannes au moyen d'organes de fixation 17 (Figures 2 et 3) disposés dans certains creux d'onde 8.
  • (b) On pose un certain nombre de plaques isolantes 3.
  • (c) Au droit d'une panne 1 chevauchée par ces plaques, on dispose une rangée de plaquettes 4 ou une bande souple 4. Si on utilise des plaquettes, on les pose à l'aplomb de plages 7 des tôles 2, par exemple à raison d'une toutes les quatre plages ou toutes les deux plages.
  • (d) Sur chaque plaquette on pose une rondelle 5, ou bien sur chaque bande 4 on pose des feuillards ou une rangée de rondelles 5 situées comme indiqué ci-dessus pour les plaquettes 4.
  • (e) On visse une vis 6 dans chaque rondelle 5 ou bien à des emplacements correspondants des feuillards 5. Ces vis traversent les plaquettes ou la bande 4, la plaque 3 et les plages 7 concernées, puis se vissent dans la branche supérieure de la panne, avec leur tête 12 en appui sur une rondelle ou un feuillard 5. Dans le cas d'utilisation de feuillards 5, ceux-ci peuvent être prépercés pour faciliter l'introduction des vis 6.
  • (f) On répète les opérations (b) à (e) pour toutes les pannes chevauchées par les plaques 3 déjà en place, puis pour les autres parties de la couverture.
  • (g) Enfin, on déroule le revêtement d'étanchéité 18, constitué d'une matière synthétique souple tel que le PVC ou d'un produit bitumineux, tout en le fixant par collage ou soudage sur les plaquettes ou la bande 4 et éventuellement sur les rondelles ou les feuillards 5. Bien entendu, les lés du revêtement d'étanchéité sont collés ou soudés entre eux dans leurs zones de recouvrement.
The installation of this cover is carried out as follows.
  • (a) The ribbed steel sheets 2 are placed on the purlins and, if necessary, their temporary fixing is ensured on these purlins by means of fastening members 17 (Figures 2 and 3) arranged in certain recesses wave 8.
  • (b) A number of insulating plates 3 are placed.
  • (c) In line with a breakdown 1 overlapped by these plates, there is a row of plates 4 or a flexible strip 4. If plates are used, they are placed directly above the areas 7 of the sheets 2, for example at the rate of one every four tracks or every two tracks.
  • (d) On each wafer we place a washer 5, or on each strip 4 we put strips or a row of washers 5 located as indicated above for the wafers 4.
  • (e) A screw 6 is screwed into each washer 5 or else to corresponding locations of the strips 5. These screws pass through the plates or the strip 4, the plate 3 and the pads 7 concerned, then are screwed into the upper branch of the purlin, with their head 12 resting on a washer or a strip 5. In the case of the use of strips 5, these can be pre-drilled to facilitate the introduction of the screws 6.
  • (f) Repeat operations (b) to (e) for all the failures overlapped by the plates 3 already in place, then for the other parts of the cover.
  • (g) Finally, the sealing coating 18, consisting of a flexible synthetic material such as PVC or a bituminous product, is unwound, while fixing it by gluing or welding on the wafers or the strip 4 and optionally on the washers or the strips 5. Of course, the strips of the sealing coating are glued or welded together in their overlap zones.

On obtient ainsi une couverture étanche facile à poser dans laquelle les vis de fixation sont pratiquement invisibles. De plus, les efforts d'arrachement dus au vent qui s'exercent sur le revêtement d'étanchéité sont directement transmis aux pannes 1 par l'intermédiaire des vis de fixation 6, le revêtement n'étant pas fixé aux plaques isolantes 3 ni aux tôles d'acier nervuré 2.An easy-to-install waterproof cover is thus obtained in which the fixing screws are practically invisible. In addition, the wind-off forces exerted on the waterproofing coating are directly transmitted to the purlins 1 via the fixing screws 6, the coating not being fixed to the insulating plates 3 or to the ribbed steel sheets 2.

Il est également à noter :

  • d'une part, que la longueur des vis 6 n'est pas critique, de sorte que les mêmes vis peuvent être utilisées avec une grande variété de tôles d'acier nervuré et d'épaisseurs de plaques isolantes;
  • d'autre part, que les efforts de compression (dus au vent et aux charges d'exploitation telles que eau, neige, circulation d'entretien...) sont exercés sur le revêtement d'étanchéité puis sont transmis aux plaques d'isolation thermique 3, puis sont transmis aux tôles d'acier nervuré 2, sans nécessiter de fixation de celles-ci, puis aux pannes 1. Les tôles d'acier nervuré sont donc calculées en fonction de ces seuls efforts de compression et de l'écartement entre les pannes 1, et non en fonction des charges de dépression dus au vent.
It should also be noted:
  • on the one hand, that the length of the screws 6 is not critical, so that the same screws can be used with a wide variety of ribbed steel sheets and thicknesses of insulating plates;
  • on the other hand, that the compression forces (due to wind and operating loads such as water, snow, maintenance traffic, etc.) are exerted on the waterproofing coating, then they are transmitted to the thermal insulation plates 3, then are transmitted to the ribbed steel sheets 2, without requiring fixing of these, then to the purlins 1. The ribbed steel sheets are therefore calculated as a function of these compression forces alone and of the spacing between the purlins 1, and not as a function of the vacuum loads due to the wind.

La résistance à la traction des vis 6 dépend de l'écartement des pannes, des forces de dépression dues au vent (et donc de la région géographique) et de l'écartement entre vis au-dessus d'une même panne. Par exemple, en France, pour des distances entre pannes de 3 m et entre fixations sur une même panne d'environ 0,50 m (toutes les deux ondes des tôles 2), la résistance à la traction des vis 6 ne sera pas inférieure à 3000 N et sera de préférence de 5000 N avec un coefficient de sécurité de l'ordre de 1,5.The tensile strength of the screws 6 depends on the spacing of the purlins, the vacuum forces due to the wind (and therefore on the geographic region) and on the spacing between the screws above the same purlin. For example, in France, for distances between purlins of 3 m and between fixings on the same purlin of about 0.50 m (every two waves of the sheets 2), the tensile strength of the screws 6 will not be less at 3000 N and will preferably be 5000 N with a safety factor of the order of 1.5.

De façon générale, on dimensionne les constituants 4 à 6 de la couverture de manière à obtenir partout une homogénéité approximative des performances à la traction et /ou à la déchirure vis-à-vis des efforts d'arrachement perpendiculaires à la toiture ou parallèles à celle-ci : résistance à la traction entre les vis 6 et les pannes, résistance à la traction entre les têtes 12 des vis 6 et les rondelles ou les feuillards 5, résistance à la traction, perpendiculairement à la toiture, entre les plaquettes ou la bande 4 et les rondelles ou les feuillards 5, résistance à la déchirure entre les plaquettes ou les bandes 4 et la tige des vis 6, vis-à-vis des efforts parallèles à la toiture, résistance du collage ou du soudage entre le revêtement d'étanchéité et les plaquettes ou les bandes 4 et/ou les rondelles ou les feuillards 5.In general, the components 4 to 6 of the cover are dimensioned so as to obtain everywhere an approximate homogeneity of the tensile and / or tear performances with respect to the tearing forces perpendicular to the roof or parallel to this: tensile strength between the screws 6 and the purlins, tensile strength between the heads 12 of the screws 6 and the washers or strips 5, tensile strength, perpendicular to the roof, between the plates or the strip 4 and the washers or the strips 5, tear resistance between the plates or strips 4 and the rod of the screws 6, with respect to forces parallel to the roof, resistance of bonding or welding between the coating '' sealing and plates or bands 4 and / or washers or strips 5.

La cuvette ou les nervures 11 des organes d'appui 5 réduisent le risque de perforation du revêtement d'étanchéité par les têtes des vis 6.The bowl or ribs 11 of the supporting members 5 reduce the risk of perforation of the coating sealing by the heads of the screws 6.

Comme représenté en traits mixtes à la Figure 5, les vis 6 peuvent traverser une entretoise tubulaire métallique 19 interposée entre la face supérieure de la tôle d'acier nervuré 2 et l'ensemble 4-5. Ceci permet d'éviter, sous l'effet de la circulation d'entretien, la perforation du revêtement d'étanchéité par les têtes de fixation 12, surtout avec des plaques d'isolation thermique 3 souples et compressibles.As shown in phantom in Figure 5, the screws 6 can pass through a metal tubular spacer 19 interposed between the upper face of the ribbed steel sheet 2 and the assembly 4-5. This makes it possible to avoid, under the effect of the maintenance circulation, the perforation of the sealing coating by the fixing heads 12, especially with flexible and compressible thermal insulation plates 3.

Le mode de réalisation des Figures 6 et 7 diffère du précédent par le fait que les efforts d'arrachement sont transmis aux pannes 1 de façon indirecte, par l'intermédiaire des tôles d'acier nervuré. Pour cela, les tôles 2, qui sont réalisées de façon plus rigide que précédemment, sont fixées fermement aux pannes, au moyen de fixations 17 prévues dans chaque creux d'onde, et le nombre des vis 6 est augmenté, par exemple, comme représenté, à deux par plage 7. Une telle disposition peut être intéressante dans des régions peu ventées.The embodiment of Figures 6 and 7 differs from the previous one in that the tearing forces are transmitted to the purlins 1 indirectly, by means of ribbed steel sheets. For this, the sheets 2, which are made more rigidly than previously, are firmly fixed to the purlins, by means of fasteners 17 provided in each wave trough, and the number of screws 6 is increased, for example, as shown , two per track 7. Such an arrangement can be interesting in regions with little wind.

Le mode de réalisation de la Figure 8 diffère de celui des Figures 1 à 5 sous deux aspects : d'une part, les rondelles 5 sont planes et soudées à la tige des vis 6. D'autre part, ces vis comportent, au-dessus de la rondelle 5, un prolongement 20 qui traverse le revêtement d'étanchéité et qui dépasse légèrement au-dessus de celui-ci. Ce prolongement est fileté et reçoit par vissage la douille inférieure taraudée 21 d'un support 22. La partie supérieure 23 de ce support est filetée, et sur elle se visse, à une hauteur réglable, une platine 24. Une lisse 25 est fixée sur l'ensemble des platines 24 d'une même rangée, et une surtoiture 26 ayant essentiellement un but esthétique, non étanche, se fixe sur les lisses 25.The embodiment of FIG. 8 differs from that of FIGS. 1 to 5 in two aspects: on the one hand, the washers 5 are flat and welded to the rod of the screws 6. On the other hand, these screws comprise, au- above the washer 5, an extension 20 which passes through the sealing coating and which projects slightly above it. This extension is threaded and receives by screwing the lower threaded bush 21 of a support 22. The upper part 23 of this support is threaded, and on it is screwed, at an adjustable height, a plate 24. A rail 25 is fixed on all of the plates 24 of the same row, and an over-roof 26 having essentially an aesthetic, non-watertight purpose, is fixed on the rails 25.

Dans ce mode de réalisation, pour faciliter la pose du revêtement d'étanchéité, on peut commencer par visser sur les prolongements 20 un bouchon provisoire 26 à tête pointue tel que représenté sur la Figure 9. Ces bouchons perforent facilement le revêtement 18, et peuvent ensuite être retirés pour permettre le vissage des supports 22.In this embodiment, to facilitate the installation of the waterproofing covering, one can start by screw a temporary cap 26 with a pointed head as shown in FIG. 9 onto the extensions 20. These plugs easily perforate the coating 18, and can then be removed to allow the supports 22 to be screwed.

Dans le mode de réalisation de la Figure 8, l'étanchéité de la couverture est obtenue grâce au collage ou au soudage du revêtement 18 sur les éléments 4 et 5, tout autour du prolongement 20 de chaque vis 6.In the embodiment of FIG. 8, the sealing of the covering is obtained by gluing or welding the covering 18 on the elements 4 and 5, all around the extension 20 of each screw 6.

En variante, dans chacun des modes de réalisation décrit ci-dessus, les organes d'appui 5 peuvent être solidaires des organes de liaison 4 ou même venus de matière avec eux, notamment lorsque les organes 4 sont constitués de métal revêtu.As a variant, in each of the embodiments described above, the support members 5 can be integral with the connecting members 4 or even integral with them, in particular when the members 4 are made of coated metal.
