Description

La présente invention concerne le domaine de l'industrie du bâtiment et des travaux publics, en particulier le domaine de la fabrication de matériels de chantiers et à pour objet un dispositif de coffrage en matériau composite.The present invention relates to the field of the building and public works, especially manufacturing of building site materials and for the purpose of a formwork device in composite material.

Actuellement le coffrage de murs et de planchers est généralement effectué au moyen, respectivement, de banches et de tables de coffrage.Currently the formwork for walls and floors is generally carried out by means of formwork and tables respectively formwork.

Ainsi, il existe divers types de banches permettant la réalisation de murs et qui sont généralement constituées par une surface de coffrage proprement dite, par des moyens d'appui au sol et de réglage de la verticalité et par des moyens d'assemblage de banches voisines entre elles.Thus, there are various types of formwork allowing the realization of walls and which generally consist of a formwork surface proper, by means of support on the ground and adjustment of the verticality and by means of assembling neighboring forms between them.

Ces banches connues sont pourvues, en outre, de dispositifs annexes de sécurité, tels que des passerelles de circulation ou analogues et leurs divers éléments constitutifs sont assemblés par l'intermédiaire de boulons ou de broches.These known forms are further provided with devices safety annexes, such as traffic gangways or the like and their various components are assembled through bolts or pins.

Les tables de coffrage présentent une certaine analogie, dans leur constitution, avec les banches, seuls les moyens de support et de réglage de leur horizontalité étant différents.Formwork tables have a certain analogy, in their constitution, with the formwork, only the means of support and adjusting their horizontality being different.

Les faces coffrantes des banches et tables connues sont réalisées, soit en une tôle soudée sur l'infrastructure de support et d'étaiement, soit en panneaux contreplaqués vissés sur ladite infrastructure.The shuttering faces of known forms and tables are made, either in sheet metal welded to the support infrastructure and shoring, either in plywood panels screwed to said infrastructure.

Ces banches et tables de coffrage connues permettent, généralement, l'obtention d'un fini de surface correct lorsque leurs faces coffrantes sont encore relativement nouvelles. Toutefois, ces dernières sont soumises à une usure relativement rapide entraínant une dégradation de leur surface ayant pour conséquence un collage du béton au décoffrage, et donc des difficultés pour réaliser ce dernier. En outre, les imperfections de surface des faces coffrantes entraínent également la nécessité d'un ragréage de la surface correspondante du mur ou du plancher coulé. Enfin, pour éviter un recours fréquent à de tels ragréages de surface, un changement relativement fréquent de la face coffrante est nécessaire, entraínant une immobilisation en conséquence de la banche ou de la table de coffrage et une dépense importante de main-d'oeuvre, qui se répercute sur les frais d'exploitation. These known forms and formwork tables allow, generally, obtaining a correct surface finish when their faces formwork are still relatively new. However, these are subject to relatively rapid wear causing degradation of their surface resulting in bonding of concrete to formwork, and therefore difficulties in achieving the latter. In addition, the imperfections of surface of the formwork faces also entails the need for a leveling of the corresponding surface of the wall or of the poured floor. Finally, for avoid frequent use of such surface resurfacing, a change relatively frequent the formwork side is necessary, resulting in immobilization as a result of the formwork or the formwork table and a significant labor expenditure, which affects the costs operating.

De plus, ces banches et tables de coffrage sont d'un poids unitaire très élevé et la constitution de leur face coffrante ne permet pas une isolation thermique du béton coulé par rapport à l'atmosphère ambiante, ce qui peut être préjudiciable à un durcissement homogène du béton, aussi bien en période de froid qu'en période de grande chaleur.In addition, these forms and formwork tables are heavy very high unit and the constitution of their formwork face does not allow a thermal insulation of the poured concrete from the ambient atmosphere, which can be detrimental to a uniform hardening of the concrete, too both in cold weather and in hot weather.

En outre, le montage de réservations entre les banches connues, en particulier des éléments de moulage d'ouvertures dans les murs, est particulièrement difficile à réaliser et nécessite un outillage spécifique.In addition, the setting up of reservations between the known forms, in particular elements for molding openings in the walls, is particularly difficult to achieve and requires specific tools.

Pour obvier à ces inconvénients, il a été proposé, par FR-A-2 648 171, des banches ou tables de coffrage présentant une infrastructure métallique et pourvu d'une face coffrante réalisée en matériau composite. Dans un tel cas, les faces coffrantes sont réalisées sous forme de panneaux sandwichs de relativement faible épaisseur, ces panneaux présentant une face coffrante parfaitement plane et lisse et des couches d'inserts en des matériaux de remplissage relativement rigide, éventuellement alvéolées et permettant l'obtention d'une certaine isolation thermique.To overcome these drawbacks, it has been proposed by FR-A-2 648 171, formwork formwork tables or tables metallic and provided with a formwork face made of composite material. In such a case, the shuttering faces are made in the form of panels relatively thin sandwiches, these panels having a perfectly flat and smooth formwork face and layers of inserts in relatively rigid filling materials, possibly honeycombed and allowing to obtain a certain thermal insulation.

Des banches notamment obtenues conformément au mode de réalisation proposé par ce document permettent, certes, d'améliorer le fini de surface sur une longue durée, mais, cependant, l'incidence, sur le poids total d'une banche, de l'utilisation d'une face coffrante en matériau composite est pratiquement négligeable.Formwork in particular obtained in accordance with the method of realization proposed by this document allow, certainly, to improve the finish of surface over a long period of time, but, however, the impact, on the weight total of a form, using a formwork face in material composite is practically negligible.

Il a également été proposé d'utiliser directement des panneaux en matière synthétique réalisés par estampage avec une face arrière cloisonnée. Toutefois, de tels panneaux ne sont pas suffisamment rigides pour être utilisés sans moyen d'étaiement métallique habituel et, en outre, ils ne permettent qu'une faible pression de travail.It has also been proposed to use panels directly synthetic material made by stamping with a rear face stovepipe. However, such panels are not rigid enough to be used without the usual metal shoring means and, moreover, they only allow a low working pressure.

On connaít également des panneaux de coffrage modulaire comportant deux faces en matière composite qui sont reliées entre elles par une mousse extensible assurant la cohésion de l'ensemble, un certain degré d'isolation ainsi qu'une certaine résistance à la flexion et donc une certaine rigidité.We also know modular formwork panels comprising two faces of composite material which are interconnected by an extensible foam ensuring the cohesion of the whole, a certain degree of insulation as well as a certain resistance to bending and therefore a certain rigidity.

Toutefois, ces panneaux connus présentent des inconvénients comparables aux panneaux de type sandwich intégrant une ou plusieurs couches de matériaux alvéolaires ou autres. De plus, ces panneaux ne sont, non plus, utilisables seuls pour supporter une poussée horizontale ou une poussée verticale, c'est-à-dire sans moyen d'étaiement sous forme d'une structure ou d'une infrastructure métallique ou analogue. However, these known panels have drawbacks comparable to sandwich type panels incorporating one or more layers of cellular or other materials. In addition, these panels are not, also, usable alone to support a horizontal thrust or a vertical thrust, i.e. without shoring in the form of a metallic structure or infrastructure or the like.

La présente invention a pour but de pallier ces inconvénients en proposant un dispositif de coffrage en matériau composite permettant d'éviter la mise en oeuvre de moyens supplémentaires de raidissage.The object of the present invention is to overcome these drawbacks by proposing a formwork device in composite material allowing to avoid the use of additional stiffening means.

A cet effet, le dispositif de coffrage conforme à l'invention est caractérisé en ce qu'il est essentiellement constitué par un panneau pultrudé formant face coffrante et intégrant les moyens de raidissage, par un ensemble plate-forme et garde-corps réalisé par un assemblage de tubes pultrudés et comportant un plateau de plate-forme pultrudé et par une échelle d'accès, dont les montants sont réalisés en tubes pultrudés et dont les barreaux sont clavetés entre les montants.To this end, the formwork device according to the invention is characterized in that it is essentially constituted by a pultruded panel forming a shuttering face and integrating the stiffening means, by a platform and railing assembly produced by an assembly of tubes pultruded and comprising a pultruded platform tray and by a access ladder, the uprights of which are made of pultruded tubes and of which the bars are keyed between the uprights.

    • Les figures 1 à 3 des dessins annexés représentent un dispositif de coffrage conforme à l'invention, qui est essentiellement constitué par un panneau pultrudé 1 formant face coffrante et intégrant les moyens de raidissage, par un ensemble 2 plate-forme et garde-corps réalisé par un assemblage de tubes pultrudés et comportant un plateau de plate-forme pultrudé 3 et par une échelle d'accès 4, dont les montants sont réalisés en tubes pultrudés et dont les barreaux sont clavetés entre les montants.Figures 1 to 3 of the accompanying drawings show a device formwork according to the invention, which essentially consists of a pultruded panel 1 forming a shuttering face and integrating the means of stiffening, by a set of 2 platforms and railings made by a assembly of pultruded tubes and comprising a platform tray pultruded 3 and by an access ladder 4, the amounts of which are made in pultruded tubes and whose bars are keyed between the uprights.

    Le panneau pultrudé 1 formant face coffrante, représenté plus particulièrement à la figure 4 des dessins annexés, est avantageusement réalisé par pultrusion en une seule opération et comporte deux faces planes parallèles 1' reliées et raidies par des entretoises 1" solidaires desdites faces 1'.The pultruded panel 1 forming a formwork face, shown more particularly in Figure 4 of the accompanying drawings, is advantageously produced by pultrusion in a single operation and has two flat faces 1 'parallel connected and stiffened by spacers 1 "integral with said faces 1 '.

    Selon une caractéristique de l'invention, ce panneau pultrudé 1 formant face coffrante est pourvu, comme le montrent les figures 1 à 3 et 6 des dessins annexés, de moyens 5 d'articulation pour des éléments repliables tels que le support de l'ensemble plate-forme ou pour l'articulation d'étais 6 de stabilisation de la banche et de bras de support de plate-forme 7, ainsi que de dispositifs 8 de réglage de l'affleurement de deux banches voisines ou superposées, de dispositifs 9 d'assemblage en parallèle de deux banches par coopération avec des broches de serrage 10 et des entretoises 11 (figure 6) et de vérins 21 de réglage de niveau du panneau 1, ces différents moyens 5, dispositifs 8 et 9 et vérins 21 étant avantageusement réalisés sous forme de pièces insérées dans des logements de forme correspondante découpés dans les parois du panneau 1 et fixées dans cesdits logements.According to a characteristic of the invention, this pultruded panel 1 forming the form face is provided, as shown in Figures 1 to 3 and 6 attached drawings of articulation means 5 for elements foldable such as the platform assembly support or for the articulation of props for stabilizing the form and of the support arm of platform 7, as well as devices 8 for adjusting the outcrop of two adjoining or superimposed forms, of devices 9 for assembling in parallel of two forms by cooperation with clamping pins 10 and spacers 11 (FIG. 6) and cylinders 21 for adjusting the level of the panel 1, these different means 5, devices 8 and 9 and jacks 21 being advantageously produced in the form of parts inserted into housings of corresponding shape cut from the walls of panel 1 and fixed in these dwellings.

    L'ensemble 2 plate-forme et garde-corps est avantageusement constitué par un plateau de plate-forme pultrudé 3 disposé sur un cadre 12 formé par un assemblage de tubes pultrudés, par un garde-corps proprement dit 13 monté à articulation, par l'intermédiaire de charnières 14, sur le cadre 12 et également réalisé par un assemblage de tubes pultrudés, cet ensemble 2 étant articulé sur le panneau 1 par l'intermédiaire des moyens d'articulation 5 coopérant avec le cadre 12 et étant maintenu en position de service par l'intermédiaire des bras supports 7 sous forme de tubes pultrudés s'appuyant à une extrémité sur d'autres moyens d'articulation 5 et coopérant à l'extrémité opposée avec une charnière 14 de montage du garde-corps 13.The set 2 platform and railing is advantageously constituted by a pultruded platform plate 3 disposed on a frame 12 formed by an assembly of pultruded tubes, by a railing properly dit 13 articulated, by means of hinges 14, on the frame 12 and also produced by an assembly of pultruded tubes, this assembly 2 being articulated on the panel 1 by means hinge 5 cooperating with frame 12 and being held in position service via the support arms 7 in the form of pultruded tubes leaning at one end on other articulation means 5 and cooperating at the opposite end with a hinge 14 for mounting the railing 13.

    L'assemblage de tubes pultrudés constituant le cadre 12 et le garde-corps 13 est réalisé, de préférence, par emboítement d'extrémités manchonnées de manière correspondante et par rivetage et collage desdites extrémités manchonnées, après assemblage. Un tel mode de réalisation des cadre 12 et garde-corps 13 permet un montage particulièrement rapide et peu onéreux de ces éléments et ainsi, un coût de revient relativement faible.The assembly of pultruded tubes constituting the frame 12 and the railing 13 is preferably made by interlocking ends sleeved correspondingly and by riveting and gluing said sleeved ends, after assembly. Such an embodiment of frame 12 and railing 13 allows particularly rapid assembly and inexpensive of these elements and thus, a relatively low cost price.

    Le plateau de plate-forme pultrudé 3, représenté plus particulièrement à la figure 5 des dessins annexés, est réalisé en une seule opération de pultrusion et comporte deux faces planes parallèles 3' reliées et raidies par des entretoises 3" solidaires desdites faces 3'. L'une des faces 3' de ce plateau 3, à savoir celle correspondant à la surface de marche de la plate-forme est avantageusement pourvue de moyens anti-dérapants, tels qu'un nervurage 3"' ou encore tels qu'une masse à caractéristiques anti-dérapantes. Ainsi, il peut être assuré une sécurité accrue contre les risques de glissades et de chutes pouvant en résulter.The pultruded platform platform 3, shown more particularly in Figure 5 of the accompanying drawings, is made in a single pultrusion operation and has two parallel plane faces 3 'connected and stiffened by spacers 3 "integral with said faces 3 '. One of the faces 3' of this platform 3, namely that corresponding to the walking surface of the the platform is advantageously provided with non-slip means, such as than a 3 "rib or even such as a mass with non-slip characteristics. Thus, it can be ensured increased security against risks slips and falls that may result.

    L'échelle d'accès 4, dont les montants sont réalisés en tubes pultrudés et dont les barreaux sont clavetés entre les montants est préférentiellement fixée, par l'intermédiaire d'un axe traversant son barreau supérieur, à des charnières 15 intégrées dans le plateau pultrudé 3 de plate-forme et est solidarisée, en position de service de la banche, avec l'extrémité d'un marche-pied 16, dont l'autre extrémité est articulée sur la face correspondante du panneau 1 par l'intermédiaire d'une charnière 17 intégrée dans la paroi arrière du panneau 1.Access ladder 4, the uprights of which are made of tubes pultruded and whose bars are keyed between the uprights is preferably fixed, by means of an axis passing through its bar upper, with hinges 15 integrated in the pultruded plate 3 of the platform and is secured, in the service position of the form, with the end a step 16, the other end of which is articulated on the face panel 1 corresponding via an integrated hinge 17 in the rear wall of panel 1.

    De manière connue, l'extrémité de chaque étai 6, opposée à celle coopérant avec le moyen d'articulation 5, est articulée sur l'extrémité arrière d'un bracon 18, dont l'autre extrémité coopère avec un autre moyen d'articulation 5 prévu près de la partie inférieure du plateau 1. Ainsi, la banche conforme à l'invention est parfaitement stabilisée dans une position proche de sa position de service, en attente de son réglage de position définitif, un réglage de la position du panneau 1 par rapport à la verticale pouvant simplement être obtenu par actionnement des étais 6.In known manner, the end of each stay 6, opposite to that cooperating with the articulation means 5, is articulated on the end back of a container 18, the other end of which cooperates with another means articulation 5 provided near the lower part of the plate 1. Thus, the sheet according to the invention is perfectly stabilized in a position close to its service position, waiting for its position adjustment final, an adjustment of the position of the panel 1 relative to the vertical which can simply be obtained by actuating the struts 6.

    Les dispositifs 8 de réglage de l'affleurement de deux banches voisines ou superposées sont connus dans leur principe de réalisation et de fonctionnement et ne sont pas décrits plus en détail.The devices 8 for adjusting the outcrop of two forms neighboring or superimposed are known in their principle of realization and operation and are not described in more detail.

    Les dispositifs 9 d'assemblage en parallèle de deux banches par coopération avec des broches de serrage 10 et des entretoises 11, représentés plus particulièrement à la figure 6 des dessins annexés consistent avantageusement en des inserts de guidage des broches de serrage 10 et d'absorption des forces axiales de serrage exercées sur les extrémités desdites broches 10 et des entretoises 11 disposées sur les broches 10, entre deux panneaux 1 formant la face coffrante d'une banche. Dans le mode de représentation selon la figure 6, seuls deux panneaux 1 sont représentés dans une position de réalisation d'un coffrage dont les extrémités sont délimitées par des faces coffrantes calibrées 19, dont le positionnement vertical peut être assuré par l'intermédiaire d'un dispositif de retenue serré sur les extrémités correspondantes de deux panneaux 1, par l'intermédiaire des dispositifs 8 de réglage de l'affleurement.The devices 9 for assembling two forms in parallel by cooperation with clamping pins 10 and spacers 11, shown more particularly in Figure 6 of the accompanying drawings advantageously consist of guide inserts of the pins tightening 10 and absorbing the axial tightening forces exerted on the ends of said pins 10 and spacers 11 disposed on the pins 10, between two panels 1 forming the formwork face of a form. In the representation mode according to FIG. 6, only two panels 1 are shown in a position for producing a formwork whose ends are delimited by formwork faces calibrated 19, the vertical positioning can be ensured by means of a device retainer tightened on the corresponding ends of two panels 1, by through the devices 8 for adjusting the outcrop.

    Conformément à une autre caractéristique de l'invention, le panneau 1 formant la face coffrante est avantageusement pourvu, dans sa partie supérieure, de têtes de levage 20 constituées chacune par une partie apparente en saillie sur le bord supérieur du panneau 1 et par une partie insérée dans le panneau 1 et formant contre-pièce de serrage de la partie apparente, réalisant ainsi un pinçage de la paroi formant le bord supérieur.In accordance with another characteristic of the invention, the panel 1 forming the form face is advantageously provided, in its upper part, of lifting heads 20 each consisting of a part visible protruding from the upper edge of panel 1 and through a part inserted in panel 1 and forming a counter-clamping part visible, thus pinching the wall forming the upper edge.

    Le panneau 1 et le plateau 3 sont avantageusement réalisés à base de fibres de renfort d'origine minérale et/ou organique et/ou chimique et de résine thermodurcissable et/ou thermoplastique.The panel 1 and the plate 3 are advantageously made at base of reinforcing fibers of mineral and / or organic and / or chemical origin and thermosetting and / or thermoplastic resin.

    De préférence, la réalisation de ce panneau 1 et de ce plateau 3 s'effectuent par pultrusion avec guidage des fibres de renfort d'origine minérale et/ou organique et/ou chimique assemblées en forme de fils, de torons, de mats ou de tissus, à travers une filière, les fils, les torons, les mats et/ou les tissus étant préalablement enduits de résine. On obtient ainsi un panneau ou un plateau continus de largeur et d'épaisseur prédéterminées, ce panneau ou ce plateau pouvant être débités en tronçons de longueur prédéterminée en fonction des besoins. Un tel débitage à la longueur de produits réalisés en continu est effectué d'une manière connue, à savoir, par exemple, par l'intermédiaire d'un dispositif de tronçonnage transversal accompagnant le déplacement longitudinal du produit en défilement et revenant à une position de départ après une passe de tronçonnage transversal.Preferably, the production of this panel 1 and of this plate 3 are carried out by pultrusion with guidance of the original reinforcing fibers mineral and / or organic and / or chemical assembled in the form of wires, strands, mats or fabrics, through a die, the wires, the strands, the mats and / or the fabrics being previously coated with resin. We thus obtain a continuous panel or tray of predetermined width and thickness, this panel or tray that can be cut into lengthwise sections predetermined according to needs. Such debitage over the length of continuously produced is carried out in a known manner, namely, by example, via a cross-cutting device accompanying the longitudinal displacement of the product while scrolling and returning to a starting position after a cutting pass transverse.

    Le guidage des fibres de renfort à l'entrée de la filière s'effectue par l'intermédiaire d'une forme de canevas présentant des alignements horizontaux et verticaux et/ou obliques de perçages destinés chacun au guidage d'un ou de plusieurs fils, torons, torons et/ou tissus enduits, avant leur entrée dans la filière. Il en résulte que le panneau ou le plateau composites obtenus présentera des renforcements de structure parfaitement positionnés et dimensionnés dans ses parties constitutives, à savoir, d'une part, dans les faces planes parallèles et, d'autre part, dans les entretoises de liaison et de raidissage solidaires desdites faces.The reinforcement fibers are guided at the entrance to the die via a canvas form with alignments horizontal and vertical and / or oblique of holes each intended for guiding one or more wires, strands, strands and / or coated fabrics, before their entry into the sector. As a result, the panel or the tray composites obtained will present structural reinforcements perfectly positioned and dimensioned in its constituent parts, namely, of a on the one hand, in the parallel flat faces and, on the other hand, in the spacers of connection and stiffening integral with said faces.

    Le mode de réalisation des différents éléments de la banche conforme à l'invention avec possibilité d'articulation entre eux et de démontage éventuel de leur point d'ancrage aux extrémités permet un repliage total de ces éléments les uns sur les autres avec disposition des éléments entièrement démontés tels que l'échelle 4 dans des espaces vides entre des parties en saillie. Ainsi, il est possible, après désolidarisation d'une extrémité des bras supports de l'ensemble 2 de plate-forme et de garde-corps, de rabattre ladite plate-forme avec son cadre contre la face arrière du panneau 1, de loger le bras de support dans les espaces vides et de rabattre le garde-corps proprement dit 13 par dessus le plateau 3. L'échelle 4 pourra être disposée dans un espace vide délimité entre des parties en saillie des moyens et dispositifs 5, 8 et 9. Les étais 6 et les bracons peuvent également être repliés dans ces espaces.The embodiment of the different elements of the form in accordance with the invention with the possibility of articulation between them and of possible dismantling of their anchor point at the ends allows a total folding of these elements one on the other with arrangement of fully dismantled elements such as ladder 4 in empty spaces between protruding parts. Thus, it is possible, after separation of a end of the support arms of the platform 2 and railing assembly 2, to fold the said platform with its frame against the rear face of the panel 1, to place the support arm in the empty spaces and to fold down the actual railing 13 over the tray 3. The ladder 4 may be arranged in an empty space delimited between protruding parts of the means and devices 5, 8 and 9. The props 6 and the bracons can also be folded into these spaces.

    Il en résulte que la banche conforme à l'invention est entièrement repliable et colisable en un encombrement restreint. En outre, la constitution du panneau 1 et du plateau 3 sous forme d'éléments creux en matière composite réalisée par pultrusion ainsi que la réalisation par pultrusion des éléments de garde-corps, permettent une réduction significative du poids de la banche, de sorte que la capacité de levage des grues de manutention peut être réduite ou que lesdites grues peuvent manoeuvrer, à chaque opération, une surface de coffrage plus importante.It follows that the formwork according to the invention is fully collapsible and packable in a small footprint. In addition, the constitution of the panel 1 and of the plate 3 in the form of hollow elements in composite material produced by pultrusion as well as production by pultrusion of the railing elements, allow a reduction the weight of the form, so that the lifting capacity of handling cranes can be reduced or that said cranes can operate a larger formwork area at each operation.

    De plus, la réalisation de la face coffrante en un matériau composite permet de supprimer totalement l'utilisation des huiles de décoffrage ainsi que des huiles de stockage de sorte que la pollution de l'environnement peut être considérablement réduite.In addition, the realization of the form face in a material composite completely eliminates the use of formwork as well as storage oils so that pollution from the environment can be greatly reduced.

    Enfin, la constitution des panneaux 1 permet l'obtention d'un effet thermique bénéfique sur le béton, dont la prise peut être accélérée. Cet effet thermique est particulièrement bénéfique dans les périodes froides et/ou dans le cas d'utilisation de bétons spéciaux.Finally, the constitution of the panels 1 makes it possible to obtain a beneficial thermal effect on concrete, which setting can be accelerated. This thermal effect is particularly beneficial in cold periods and / or in the case of the use of special concretes.

    Grâce à l'invention, il est possible de réaliser une banche présentant une majorité de pièces structurelles en matière composite pultrudée et dont le poids est considérablement réduit par rapport à celui de banche de même dimension.Thanks to the invention, it is possible to make a sheet with a majority of structural parts in composite material pultruded and whose weight is considerably reduced compared to that of form of the same size.

    En outre, du fait de la réalisation du panneau 1 sous forme de panneaux creux, l'inertie de ce panneau, par rapport à des panneaux de même poids par unité de surface est considérablement augmentée et sa rigidité est augmentée en conséquence, de sorte que, pour un poids par unité de surface donnée, le panneau lest nettement plus résistant.In addition, due to the realization of the panel 1 in the form of hollow panels, the inertia of this panel, compared to panels of same weight per unit area is considerably increased and its rigidity is increased accordingly, so that for a weight per unit of given surface, the panel is significantly more resistant.

    Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the mode of embodiment described and shown in the accompanying drawings. Modifications remain possible, especially from the point of view of the constitution of the various elements or by substitution of technical equivalents, without leaving for as much of the scope of protection of the invention.
