Description

L'invention concerne un panneau, et son procédé de réalisation, selon le préambule des revendications 13 et 1.The invention relates to a panel, and its production method, according to the preamble of claims 13 and 1.

On connaît des panneaux pleins utilisables notamment comme ridelles, constitués par une pluralité d'éléments de remplissage coplanaires juxtaposés, auto-portants et directement fixés au châssis qui les supporte. De tels panneaux ne nécessitent pas de charpente ou de montants intermédiaires. Chaque élément de remplissage a, en section droite transversale horizontale, une forme de U aplati ayant une âme pleine et lisse extérieurement et deux ailes tournées vers la face interne de la ridelle. Deux éléments de remplissage adjacents sont rigidement solidarisés entre eux, à l'endroit de leurs ailes, au moyen de perforations réalisées dans les ailes avec lesquelles coopèrent des rivets.Solid panels are known which can be used in particular as drop sides, constituted by a plurality of juxtaposed coplanar filling elements, self-supporting and directly fixed to the frame which supports them. Such panels do not require a frame or intermediate uprights. Each filling element has, in horizontal cross section, a flattened U shape having a solid and smooth core on the outside and two wings facing the internal face of the drop side. Two adjacent filling elements are rigidly joined together, at the location of their wings, by means of perforations made in the wings with which the rivets cooperate.

Entre les ailes contiguês, on place un joint d'étanchéité. Ce joint se présente sous la forme d'une bande ayant sensiblement la forme et les dimensions des ailes et notamment en élastomère. Ce joint peut comporter des perforations correspondant aux perforations des ailes et permettant l'introduction des organes de solidarisation des éléments de remplissage. Par ailleurs, les ailes peuvent comporter des retours d'ailes. Ainsi les éléments de remplissage ont une forme d'U aplati.Between the adjoining wings, a seal is placed. This seal is in the form of a strip having substantially the shape and dimensions of the wings and in particular of elastomer. This seal may include perforations corresponding to the perforations of the wings and allowing the introduction of the fastening members of the filling elements. Furthermore, the wings may include wing returns. Thus the filling elements have a flattened U shape.

De tels panneaux présentent des avantages certains ; les rivets de liaison des éléments ne sont pas apparents et ne saillent pas, les éléments de remplissage ont une âme plane ce qui fait que la surface de la ridelle montée, dirigée vers l'extérieur, est plane et permet l'éventuelle décoration extérieure de la ridelle et le nettoyage en est facilité.Such panels have certain advantages; the connecting rivets of the elements are not visible and do not protrude, the filling elements have a flat core, which means that the surface of the mounted drop side, directed towards the outside, is flat and allows the possible external decoration of the drop side and cleaning is facilitated.

Cependant, ces panneaux, comportent des inconvénients. En effet, les éléments de remplissage sont fabriqués à partir de plaques métalliques planes, et les bords des ailes ou des retours d'ailes sont coupants. Ainsi, lors du montage de la ridelle, les ouvriers doivent se protéger les mains. Par ailleurs, si la surface extérieure de la ridelle est plane, la surface intérieure comprend des arêtes vives formées par les bords des ailes ou des retours d'ailes. Par conséquent, on ne peut envisager d'utiliser les ridelles ainsi fabriquées pour des camions transportant des objets fragiles, par exemple des meubles, qui sont alors inévitablement rayés par les bords vifs des ailes. De plus, l'aspect esthétique de l'intérieur de la ridelle n'est pas satisfaisant. En outre, le joint disposé entre les ailes de deux éléments de remplissage est visible à l'extérieur. Là encore, l'aspect général de la ridelle laisse à désirer car la couleur du joint tranche inévitablement avec la couleur du panneau.These panels, however, have drawbacks. Indeed, the filling elements are made from flat metal plates, and the edges of the wings or wing returns are sharp. Thus, when mounting the drop side, the workers must protect their hands. Furthermore, if the outer surface of the drop side is planar, the inner surface includes sharp edges formed by the edges of the wings or wing returns. Consequently, it is not possible to envisage using the sideboards thus manufactured for trucks transporting fragile objects, for example furniture, which are then inevitably scratched by the sharp edges of the wings. In addition, the aesthetic appearance of the interior of the side wall is not satisfactory. In addition, the seal disposed between the wings of two filling elements is visible on the outside. Again, the overall appearance of the drop side leaves something to be desired because the color of the joint inevitably contrasts with the color of the panel.

Le brevet américain n° 3 055 460 décrit, par ailleurs, un panneau rigide constitué d'éléments de remplissage dont les retours d'ailes sont sertis par des éléments de renforcement coopérant avec des éléments de liaison. Mais, ces panneaux sont tels que les éléments de liaison ont pour fonction de conférer l'étanchéité entre deux éléments de remplissage contigus et cette étanchéité laisse souvent à désirer car les éléments de liaison étant fixés par écrous-boulons, ils peuvent se désolidariser. De plus, une surface externe n'est pas plane, les éléments de liaison faisant saillie.American patent n ° 3 055 460 describes, moreover, a rigid panel made up of filling elements, the wing returns of which are crimped by reinforcing elements cooperating with connecting elements. However, these panels are such that the connecting elements have the function of imparting tightness between two contiguous filling elements and this tightness often leaves something to be desired since the connecting elements being fixed by bolt nuts, they can become detached. In addition, an external surface is not planar, the connecting elements projecting.

L'invention a donc pour objet de remédier à ces inconvénients. A cet effet, elle propose un procédé de réalisation d'un panneau rigide plein, par juxtaposition et fixation d'une pluralité d'éléments de remplissage coplanaires, ayant en section droite transversale une forme générale de U aplati, comportant chacun une âme plane et deux ailes tournées vers la face interne, deux retours d'ailes tournées vers l'intrados de l'âme de l'élément de remplissage, un logement étant prévu sur au moins une des faces externes des ailes de l'élément, les âmes de deux éléments de remplissage adjacents étant coplanaires et leurs ailes tournées d'un même côté, procédé selon lequel on dispose entre deux ailes contiguës de deux éléments de remplissage adjacents un matériau d'étanchéité déformable que l'on comprime entre les deux ailes des éléments de remplissage contigus en rapprochant les ailes pour qu'il vienne remplir au moins partiellement le logement sans diffuser vers la surface extérieure du panneau.The object of the invention is therefore to remedy these drawbacks. To this end, it proposes a method of producing a solid rigid panel, by juxtaposition and fixing of a plurality of coplanar filling elements, having in cross-section a general shape of a flattened U, each comprising a flat core and two wings facing the internal face, two wing returns facing the underside of the core of the filling element, a housing being provided on at least one of the external faces of the wings of the element, the cores of two adjacent filling elements being coplanar and their wings turned towards the same side, method according to which there is between two adjacent wings of two adjacent filling elements a deformable sealing material which is compressed between the two wings of the contiguous filling by bringing the wings together so that it comes to fill at least partially the housing without diffusing towards the external surface of the panel.

Le matériau d'étanchéité se dilate selon une direction perpendiculaire à cette ligne. Cependant, il ne diffuse pas jusqu'à l'extérieur du panneau ainsi réalisé. Le joint formé est donc invisible de l'extérieur.The sealing material expands in a direction perpendicular to this line. However, it does not diffuse to the outside of the panel thus produced. The formed joint is therefore invisible from the outside.

L'invention concerne aussi un panneau rigide plein. Il est constitué d'éléments de remplissage coplanaires, ayant en section droite transversale une forme d'U aplati comportant chacun une âme plane, deux ailes tournées vers la face interne de l'âme et deux retours d'ailes tournés vers l'intrados de l'élément de remplissage, un logement étant prévu sur au moins une des faces externes des ailes de l'élément, les retours d'ailes étant sertis d'éléments de renforcement coopérant avec des éléments de liaison, les éléments de remplissage ayant en section droite la forme d'un U aplati. Un joint est disposé entre les ailes des éléments de remplissage, ce joint étant constitué d'un matériau d'étanchéité déformé remplissant au moins partiellement le logement. Ce joint ne diffuse pas vers la surface externe du panneau. Ce sont des éléments de remplissage en forme d'U aplati, dont les ailes comportent une série de perforations disposées longitudinalement et comportant chacune au moins un logement demi-cylindrique d'axe parallèle à l'axe longitudinal des ailes. Les éléments de remplissage ont une fonction multiple. Outre le renforcement, ils permettent de marquer les ailes et servent de support à des éléments de liaison, de forme sensiblement en T, en section transversale droite, qui viennent s'emboîter dans des rainures des éléments de renforcement. On obtient une surface de panneau interne plane, les différentes faces dirigées vers l'intérieur des éléments de remplissage, de renforcement et de liaison étant coplanaires.The invention also relates to a solid rigid panel. It consists of coplanar filling elements, having a flat cross-section in the form of a flattened U each comprising a flat core, two wings facing the inner face of the core and two wing returns facing the underside of the filling element, a housing being provided on at least one of the external faces of the wings of the element, the wing returns being crimped with reinforcing elements cooperating with connecting elements, the filling elements having in section right the shape of a flattened U. A seal is arranged between the wings of the filling elements, this seal consisting of a deformed sealing material at least partially filling the housing. This joint does not diffuse towards the external surface of the panel. These are flattened U-shaped filling elements, the wings of which comprise a series of perforations arranged longitudinally and each comprising at least one semi-cylindrical housing with an axis parallel to the longitudinal axis of the wings. The filling elements have a multiple function. In addition to the reinforcement, they make it possible to mark the wings and serve as support for connecting elements, of form substantially T-shaped, in cross section, which fit into grooves of the reinforcing elements. A flat internal panel surface is obtained, the different faces facing inwards of the filling, reinforcing and connecting elements being coplanar.

Les autres caractéristiques de l'invention seront bien comprises grâce à la description qui suit, en référence aux dessins annexés dans lesquels :

  • La Figure 1 est une vue schématique, en coupe, par un plan horizontal transversal d'un élément de remplissage selon l'invention.
  • La Figure 2 est une vue schématique, en coupe, par un plan horizontal transversal d'un élément de renforcement.
  • La Figure 3 est une vue schématique en coupe par un plan horizontal, transversal d'un panneau réalisé au moyen des éléments de remplissage et de renforcement ; la figure 4 est une vue schématique analogue à la figure 3, des éléments de liaison étant emboités ; la figure 5 et la figure 6 sont des vues de face respectivement externe et interne du panneau de la figure 4.
The other characteristics of the invention will be understood from the following description, with reference to the accompanying drawings in which:
  • Figure 1 is a schematic view, in section, through a horizontal transverse plane of a filling element according to the invention.
  • Figure 2 is a schematic view, in section, through a transverse horizontal plane of a reinforcing element.
  • Figure 3 is a schematic sectional view through a horizontal, transverse plane of a panel made by means of the filling and reinforcing elements; Figure 4 is a schematic view similar to Figure 3, the connecting elements being fitted; FIG. 5 and FIG. 6 are respectively external and internal front views of the panel of FIG. 4.

Un élément de remplissage 1, selon l'invention, est rigide et auto-portant. Il peut être réalisé en métal et revêtu d'une laque de couleur. Il permet de réaliser un panneau rigide plein par juxtaposition et solidarisation avec des éléments de remplissage semblables. D'une façon connue en soi, chaque élément de remplissage comporte une âme plane, de forme sensiblement rectangulaire (voir figure 5), dont la face externe est lisse et, deux ailes 3 tournées vers la face interne de l'âme 2, plus particulièrement perpendiculaires à l'âme 2. De préférence, l'élément de remplissage est muni de retours d'ailes 4 tournées vers l'intrados de l'élément de remplissage, parallèles à l'âme 2. Ainsi l'élément de remplissage a une forme générale d'U aplati, en section droite transversale. Des perforations 5 sont disposées sur un axe longitudinal de chacune des ailes, à savoir un axe perpendiculaire au plan de coupe de l'élément de remplissage 1, de préférence sur la ligne médiane de chaque aile 3. Les perforations d'une même aile sont équidistantes les unes des autres et les perforations d'une aile sont situées en regard des perforations de l'autre aile.A filling element 1, according to the invention, is rigid and self-supporting. It can be made of metal and coated with a colored lacquer. It allows a rigid rigid panel to be produced by juxtaposition and joining with similar filling elements. In a manner known per se, each filling element comprises a flat core, of substantially rectangular shape (see FIG. 5), the external face of which is smooth and, two wings 3 facing the internal face of the core 2, more particularly perpendicular to the core 2. Preferably, the filling element is provided with wing returns 4 facing towards the underside of the filling element, parallel to the core 2. Thus the filling element has a general shape of a flattened U, in cross section. Perforations 5 are arranged on a longitudinal axis of each of the wings, namely an axis perpendicular to the cutting plane of the filling element 1, preferably on the center line of each wing 3. The perforations of the same wing are equidistant from each other and the perforations of one wing are located opposite the perforations of the other wing.

Selon l'invention au moins une aile 3 comporte un logement 6 longitudinal. Celui-ci est continu, c'est-à-dire qu'il s'étend sur toute la longueur de l'aile 3.According to the invention at least one wing 3 has a longitudinal housing 6. This is continuous, that is to say that it extends over the entire length of the wing 3.

De préférence, au moins une aile 3 comporte au moins deux logements 6, 6', longitudinaux situés de part et d'autre de la ligne de perforations donc d'un axe longitudinal de l'aile. Par axe longitudinal, on entend un axe parallèle aux côtés longitudinaux de l'aile. Celle-ci étant de préférence rectangulaire, la médiane longitudinale est la médiane du rectangle délimitant l'aile. Ces logements 6, 6' ont une forme sensiblement demi-circulaire, en section droite transversale. On peut prévoir ces deux logements sur une seule des ailes ou aussi deux logements sur chacune des ailes. Ils peuvent être réalisés par profilage de la feuille métallique utilisée pour fabriquer l'élément de remplissage 1. Préférentiellement, les retours d'ailes 4 sont munis chacun à leurs extrémités libres d'un bosselage 7. Celui-ci est réalisé par exemple en repliant l'extrémité libre du retour d'aile vers l'aile, et dans une direction dirigée vers la face interne 8 de l'âme 2.Preferably, at least one wing 3 comprises at least two longitudinal housings 6, 6 ′ situated on either side of the line of perforations, therefore of a longitudinal axis of the wing. By longitudinal axis is meant an axis parallel to the longitudinal sides of the wing. The latter being preferably rectangular, the longitudinal median is the median of the rectangle delimiting the wing. These housings 6, 6 'have a substantially semicircular shape, in cross section. These two housings can be provided on only one of the wings or also two housings on each of the wings. They can be produced by profiling the metal sheet used to manufacture the filling element 1. Preferably, the wing returns 4 are each provided at their free ends with a boss 7. This is produced for example by folding the free end of the wing return towards the wing, and in a direction directed towards the internal face 8 of the core 2.

Le panneau rigide est réalisé de la façon suivante (voir figures 3 et 4) ; on dispose côte à côte plusieurs éléments de remplissage 1a, 1b, et 1c, les âmes 2a, 2b, 2c étant coplanaires et les ailes 3a, 3b et 3c étant toutes situées du même côté par rapport au plan défini par les âmes. Les perforations sont placées en regard les unes des autres, ainsi que les logements. Ceux-ci forment soit des sillons demi-cylindriques quand seule une aile comporte des logements et qu'on la place à côté d'une aile ne possédant pas de logement, soit des sillons cylindriques d'axes parallèles entre eux et parallèles à l'axe longitudinal des ailes, de section droite transversale circulaire quand chaque aile possède des logements 6 et 6'.The rigid panel is produced as follows (see Figures 3 and 4); several filling elements 1a, 1b, and 1c are placed side by side, the cores 2a, 2b, 2c being coplanar and the wings 3a, 3b and 3c being all situated on the same side relative to the plane defined by the cores. The perforations are placed facing each other, as well as the housings. These form either semi-cylindrical grooves when only one wing has housings and that it is placed next to a wing without any housing, or cylindrical grooves with axes parallel to each other and parallel to the longitudinal axis of the wings, of circular cross section when each wing has housings 6 and 6 '.

On dispose entre deux ailes contiguës un matériau d'étanchéité 9 que l'on comprime entre les deux ailes, notamment en rapprochant celles-ci grâce aux organes de solidarisation 10, par exemple des rivets. Le matériau d'étanchéité 9 est de préférence une matière déformable, par exemple un élastomère ou une matière pâteuse, à savoir un silicone. Il peut être éventuellement percé de trous correspondant aux perforations 5. On le place le long de l'axe longitudinal des ailes, plus particulièrement de la ligne médiane. Lorsqu'on comprime ce matériau selon la direction des flèches F1, F2, il se déforme et diffuse vers les extrémités des ailes, selon une direction sensiblement perpendiculaire à l'axe longitudinal des ailes. Il vient alors remplir les logements 6. Si le matériau 9 est placé en quantité importante, il remplit totalement les logements 6 et si il est placé en faible quantité, il remplit partiellement ces logements. En tout cas, il ne parvient pas jusqu'aux faces internes (8a, 8b, 8c) des éléments de remplissage. Lorsqu'on regarde le panneau ainsi réalisé, depuis l'extérieur, c'est-à-dire en direction de la flèche F3, on n'aperçoit pas le joint formé par le matériau d'étanchéité 9.There is between two contiguous wings a sealing material 9 which is compressed between the two wings, in particular by bringing them together by means of the fastening members 10, for example rivets. The sealing material 9 is preferably a deformable material, for example an elastomer or a pasty material, namely a silicone. It may possibly be pierced with holes corresponding to the perforations 5. It is placed along the longitudinal axis of the wings, more particularly of the midline. When this material is compressed in the direction of the arrows F1, F2, it deforms and diffuses towards the ends of the wings, in a direction substantially perpendicular to the longitudinal axis of the wings. It then fills the housings 6. If the material 9 is placed in a large quantity, it completely fills the housings 6 and if it is placed in small quantity, it partially fills these housings. In any case, it does not reach the internal faces (8a, 8b, 8c) of the filling elements. When we look at the panel thus produced, from the outside, that is to say in the direction of arrow F3, we do not see the joint formed by the sealing material 9.

On conçoit que la largeur des ailes du U aplati formant la section transversale droite de l'élément de remplissage 1 est très faible par rapport à la largeur L de l'âme 2. La largeur L est augmentée quand on désire augmenter la longueur de la ridelle ou du panneau réalisé. On évite ainsi d'effectuer de nombreuses fixations. Par conséquent, il est nécessaire de renforcer les fixations entre deux éléments 1 adjacents. A cet effet, on place un élément de renforcement 11 qui vient sertir les retours d'ailes contigus 4a, 4b de deux éléments de remplissage 1a, 1b adjacents. Chaque élément de renforcement 11 est placé par coulissement selon une direction parallèle à l'axe longitudinal des ailes. Il a en section droite transversale une forme générale d'U aplati ayant un fond plat 12, des côtés 13 formant un angle avec le fond plat 12, de préférence perpendiculaires, et deux bords 14 parallèles au fond 12, tourné vers l'intrados de l'élément de renforcement. La largeur des côtés 13 est sensiblement égale à la largeur des ailes de l'élément 3 de remplissage, la largeur D du fond 12 étant sensiblement supérieure au double de la largeur d des ailes de l'élément de remplissage 1, de façon à pouvoir sertir ces ailes. Dans ce cas, il n'est pas obligatoire de prévoir des bosselages 7, car les éléments de renforcement jouent un rôle protecteur puisqu'ils masquent les bords tranchants des retours d'ailes. Par ailleurs, l'élément de renforcement 11 comporte sur chaque côté 13 des rainures 15. Celles-ci sont longitudinales, s'étendent selon une direction parallèle à l'axe longitudinal des côtés 13 et leur section droite transversale a la forme d'un U dont les branches 16 et 17 sont parallèles aux bords 14. Le fond 18 de rainure est parallèle aux côtés 13. Cette structure permet d'emboîter à force un élément de liaison 19 selon une direction parallèle à l'axe longitudinal des ailes 3. L'élément de liaison 19 a une section droite transversale en forme de T. Les pattes 20 et 20' du T viennent coopérer avec les rainures 15a et 15b des deux éléments de renforcement 11a, 11 b disposés sur les deux paires d'ailes contiguës 4a, 4b et 4'b 4c des éléments de remplissage 1a, 1 b, 1 c placés côte à côte. Ainsi, tous les éléments de renforcement sont parallèles, leurs branches 14 sont toutes tournées vers les âmes 2a, 2b, 2c et leurs fonds 12a, 12b sont tous dans un même plan parallèle au plan des âmes 2a, 2b, 2c.It can be seen that the width of the wings of the flattened U forming the cross section of the filling element 1 is very small compared to the width L of the core 2. The width L is increased when it is desired to increase the length of the drop side or panel made. This avoids making many attachments. Therefore, it is necessary to strengthen the fasteners between two adjacent elements 1. To this end, a reinforcing element 11 is placed which crimps the contiguous wing returns 4a, 4b of two adjacent filling elements 1a, 1b. Each reinforcing element 11 is placed by sliding in a direction parallel to the longitudinal axis of the wings. It has in general cross section a flattened U shape having a flat bottom 12, sides 13 forming an angle with the flat bottom 12, preferably perpendicular to res, and two edges 14 parallel to the bottom 12, facing the underside of the reinforcing element. The width of the sides 13 is substantially equal to the width of the wings of the filling element 3, the width D of the bottom 12 being substantially greater than twice the width d of the wings of the filling element 1, so as to be able to crimp these wings. In this case, it is not compulsory to provide bosses 7, because the reinforcing elements play a protective role since they mask the sharp edges of the wing returns. Furthermore, the reinforcing element 11 has on each side 13 grooves 15. These are longitudinal, extend in a direction parallel to the longitudinal axis of the sides 13 and their cross section is in the form of a U whose branches 16 and 17 are parallel to the edges 14. The bottom 18 of groove is parallel to the sides 13. This structure makes it possible to force-fit a connecting element 19 in a direction parallel to the longitudinal axis of the wings 3. The connecting element 19 has a T-shaped cross section. The legs 20 and 20 ′ of the T come to cooperate with the grooves 15a and 15b of the two reinforcing elements 11a, 11b arranged on the two pairs of contiguous wings. 4a, 4b and 4'b 4c of the filling elements 1a, 1b, 1c placed side by side. Thus, all the reinforcing elements are parallel, their branches 14 are all turned towards the cores 2a, 2b, 2c and their bottoms 12a, 12b are all in the same plane parallel to the plane of the cores 2a, 2b, 2c.

Les éléments de remplissage 19 venant coulisser dans les rainures 15a, 15b de deux éléments de renforcement successifs sont disposés de façon que la surface de la barre du T vienne affleurer les surfaces des fonds 12a, 12b. Ainsi, les surfaces des fonds 12a, 12b, des éléments de renforcement et les surfaces 21 des éléments de remplissage sont coplanaires. Lorsqu'on regarde le panneau ainsi réalisé, depuis l'intérieur, c'est-à-dire en direction de la flèche F4, on ne voit que les surfaces des fonds 12a, 12b, 12c et les autres surfaces 21, 21', 21" des éléments de remplissage, les surfaces de fond 12a, 12b alternant avec les surfaces 21, 21', 21" des éléments de remplissage (cf. figure 6) et étant coplanaires.The filling elements 19 sliding in the grooves 15a, 15b of two successive reinforcing elements are arranged so that the surface of the bar of the T comes flush with the surfaces of the bottoms 12a, 12b. Thus, the surfaces of the bottoms 12a, 12b, of the reinforcing elements and the surfaces 21 of the filling elements are coplanar. When we look at the panel thus produced, from the inside, that is to say in the direction of arrow F4, we only see the surfaces of the bottoms 12a, 12b, 12c and the other surfaces 21, 21 ', 21 "of the filling elements, the bottom surfaces 12a, 12b alternating with the surfaces 21, 21 ', 21" of the filling elements (cf. FIG. 6) and being coplanar.

Le panneau réalisé plein et rigide a donc une face externe continue et une face interne elle aussi continue.The panel made full and rigid therefore has a continuous external face and an internal face which is also continuous.

Naturellement, il va de soi que l'invention peut faire l'objet de nombreuses autres variantes, formes et applications.Naturally, it goes without saying that the invention can be the subject of numerous other variants, forms and applications.
