Technique antérieurePrior art

Dans le domaine de ce type d'abri, on connaît déjà un abri de type à mât central tel que celui décrit dans la demande de brevet européen EP 1 932 983 déposée au nom de la demanderesse. Cet abri 1, selon l'état de la technique, est représenté sur la figure 1 et comporte un ensemble support 2, un élément de toiture comportant un cadre 3 en forme de quadrilatère et une toile 4 fixée par sa partie périphérique externe sur le cadre 3 et destinée à être tendue entre ledit cadre 3 et l'ensemble support 2.In the field of this type of shelter, we already know a central pole type shelter such as that described in the European patent application EP 1 932 983 filed in the name of the plaintiff. This shelter 1, according to the state of the art, is represented on the figure 1 and comprises a support assembly 2, a roof element comprising a frame 3 in the form of a quadrilateral and a cloth 4 fixed by its outer peripheral part on the frame 3 and intended to be stretched between said frame 3 and the support assembly 2.

Ledit ensemble support 2 comprend un mât central 5, une cerce 6 montée coulissante, apte à être verrouillée sur ledit mât central 5 et agencée pour recevoir la partie centrale de ladite toile 4, une bride 7 fixée sur la partie supérieure dudit mât central 5, ladite bride 7 comportant un ensemble de poulies 8 radiales aptes à recevoir chacune un câble 9, et une bague de tension 10 montée coulissante et apte à être verrouillée sur ledit mât central 5.Said support assembly 2 comprises a central mast 5, a hoop 6 mounted sliding, able to be locked on said central mast 5 and arranged to receive the central part of said fabric 4, a flange 7 fixed on the upper part of said central mast 5, said flange 7 comprising a set of radial pulleys 8 each capable of receiving a cable 9, and a tensioning ring 10 mounted to slide and able to be locked on said central mast 5.

Chaque câble 9 passe sur une des poulies 8 et a une première extrémité fixée à la bague de tension 10 et une deuxième extrémité fixée au cadre 3, ladite bague de tension 10 de l'ensemble support 2 étant verrouillée sur le mât central 5 dans une position telle que les câbles 9 sont tendus.Each cable 9 passes over one of the pulleys 8 and has a first end attached to the tension ring 10 and a second end attached to the frame 3, said tension ring 10 of the support assembly 2 being locked on the central mast 5 in a position such that the cables 9 are stretched.

Le montage de cet abri se déroule de la manière suivante. L'ensemble support 2, comprenant le mât central 5, la cerce 6, la bride 7, la bague de tension 10 et les câbles 9, est érigé. Le cadre 3 est ensuite disposé ou assemblé autour dudit ensemble support 2. La deuxième extrémité de chaque câble 9 de l'ensemble support 2 est alors fixée à des points de fixation 11 prévus sur le cadre 3. La toile 4 est fixée sur le cadre 3 par sa périphérie externe et sur la cerce 6 par sa périphérie interne définie par sa partie centrale. La bague de tension 10 est tirée vers le bas pour, d'une part, lever le cadre 3 et, d'autre part, tendre la toile 4 en poussant la cerce 6 vers le bas. Enfin, une fois la tension de toile souhaitée obtenue, la bague de tension 10 est verrouillée sur le mât central 5 dans la position finale désirée.The assembly of this shelter takes place in the following way. The support assembly 2, comprising the central mast 5, the hoop 6, the flange 7, the tension ring 10 and the cables 9, is erected. The frame 3 is then arranged or assembled around said support assembly 2. The second end of each cable 9 of the support assembly 2 is then fixed to fixing points 11 provided on the frame 3. The fabric 4 is fixed on the frame 3 by its outer periphery and on the cerce 6 by its inner periphery defined by its central part. The tensioning ring 10 is pulled down to, on the one hand, lift the frame 3 and, on the other hand, stretch the fabric 4 by pushing the hoop 6 downwards. Finally, once the desired fabric tension obtained, the tension ring 10 is locked on the central mast 5 in the desired final position.

L'ensemble support 2 selon l'état de la technique présente un certain nombre d'inconvénients. En effet, du fait de son grand nombre d'éléments constitutifs et de leur complexité, cet ensemble support 2 est particulièrement difficile et onéreux à réaliser et à mettre en ouvre.The support assembly 2 according to the state of the art has a number of disadvantages. Indeed, because of its large number of components and their complexity, this support assembly 2 is particularly difficult and expensive to achieve and implement.

Par ailleurs, lors de la fixation de la deuxième extrémité de chaque câble 9 de l'ensemble support 2 sur le cadre 3 à des points de fixation 11, si on échappe ledit câble 9 et que ce dernier se dégage de sa poulie 8 et tombe à terre, il faut alors prendre une échelle ou un échafaudage pour engager à nouveau le câble 9 dans sa poulie 8 et le fixer sur le cadre 3, car les poulies 8 sont solidaires de la bride 7 fixée sur la partie supérieure dudit mât central 5. Cette manipulation doit être réalisée avec beaucoup d'attention afin d'éviter une augmentation du coût de montage due à l'augmentation des heures de montage et l'emploi de matériels supplémentaires.Furthermore, when fixing the second end of each cable 9 of the support assembly 2 on the frame 3 at attachment points 11, if said cable 9 is escaped and the cable 9 disengages from its pulley 8 and falls on the ground, it is then necessary to take a ladder or a scaffold to engage the cable 9 again in its pulley 8 and fix it on the frame 3, because the pulleys 8 are integral with the flange 7 fixed on the upper part of said central mast 5 This manipulation must be carried out with great care in order to avoid an increase in the cost of assembly due to the increase in the hours of assembly and the use of additional materials.

Par ailleurs, pour les cadres 3 de grandes dimensions, les câbles 9 doivent être reliés à plusieurs points de fixation 11 répartis le long de chacun de côtés des cadres 3 mais également aux sommets desdits cadres 3 sous peine de voir le cadre se déformer. Les câbles 9 reliés aux sommets génèrent, compte tenu du porte-à-faux, des efforts mécaniques tels qu'il est nécessaire d'augmenter de façon significative la section desdits cadres 3 et de mettre en place des renforts 12 pour s'opposer aux sollicitations mécaniques. Enfin, cette configuration nécessite d'avoir des câbles 9 de longueur différente. Par conséquent, le coût de revient de ce type d'abri 1 est élevé car les sections du cadre 3 sont importantes et une telle configuration ne permet pas une uniformisation des éléments constitutifs dudit ensemble support 2.Furthermore, for frames 3 of large dimensions, the cables 9 must be connected to several attachment points 11 distributed along each side of the frames 3 but also to the tops of said frames 3 otherwise the frame will deform. The cables 9 connected to the vertices generate, in view of the overhang, mechanical forces such that it is necessary to significantly increase the section of said frames 3 and to set up reinforcements 12 to oppose the mechanical stresses. Finally, this configuration requires cables 9 of different length. Consequently, the cost price of this type of shelter 1 is high because the sections of the frame 3 are important and such a configuration does not allow a uniformization of the constituent elements of said support assembly 2.

Meilleure manière de réaliser l'invention techniqueBest way to realize the technical invention

On a représenté sur la figure 2 un abri léger 50 comprenant un ensemble support 51, un élément de toiture 52 comportant un cadre 53 en forme de polygone et une toile 54 fixée par son bord périphérique extérieur sur le cadre 53 et destinée à être tendue entre ledit cadre 53 et l'ensemble support 51, ladite toile 54 est pourvue dans sa partie centrale d'un orifice dont le bord définit le bord périphérique intérieur de la toile 54. Cet abri léger 50 comporte en outre un collecteur d'eau pluviale 55.We have shown on the figure 2 a light shelter 50 comprising a support assembly 51, a roof element 52 having a frame 53 in the form of a polygon and a fabric 54 fixed by its outer peripheral edge on the frame 53 and intended to be stretched between said frame 53 and the assembly 51, said fabric 54 is provided in its central part with an orifice whose edge defines the inner peripheral edge of the fabric 54. This lightweight shelter 50 further comprises a rainwater collector 55.

Conformément à l'invention, ledit élément support 51 comporte un mât central 56, des moyens de liaison 57 (voir la figure 9) montés coulissants sur ledit mât central 56 et agencés pour être verrouillés sur ledit mât central 56, , et une pluralité de câbles 58 dont l'une des extrémités est fixée sur l'extrémité supérieure dudit mât central 56, l'autre étant destinée à être fixée sur le cadre 53. Ainsi, on comprend bien que cet élément support 51 comporte peu de pièces et est par conséquent facile et rapide à mettre en oeuvre.According to the invention, said support member 51 comprises a central mast 56, connecting means 57 (see FIG. figure 9 ) slidably mounted on said central mast 56 and arranged to be locked on said central mast 56, and a plurality of cables 58 whose one end is fixed to the upper end of said central mast 56, the other being intended to be fixed on the frame 53. Thus, it is clear that this support member 51 has few parts and is therefore easy and quick to implement.

Pour des raisons de facilité de montage (décrit plus loin), l'élément support 51 comporte avantageusement une bride 59 montée coulissante sur ledit mât central 56 et agencée pour être fixée à l'extrémité supérieure dudit mât central 56 et pour recevoir l'extrémité des câbles 58.Le mât central 56 est destiné à être fixé sur un massif (non représenté) par des moyens de fixation (non représentés) tels que des crosses de scellement ou tout autre moyen analogue procurant les mêmes effets tel que des chevilles chimiques ou auto-expansives par exemple.For reasons of ease of assembly (described below), the support element 51 advantageously comprises a flange 59 slidably mounted on said central mast 56 and arranged to be fixed to the upper end of said central mast 56 and to receive the end 58. The central mast 56 is intended to be fixed on a solid mass (not shown) by fastening means (not shown) such as sealing butts or any other similar means providing the same effects such as chemical pegs or self-expanding for example.

Par ailleurs, le mât central 56 est de préférence un tube creux raccordé en partie inférieure à un dispositif d'évacuation des eaux de pluie (non représenté). De plus, ce mât central 56 comporte un orifice (non représenté) apte à coopérer avec le collecteur d'eau pluviale 55 pour évacuer vers ledit dispositif d'évacuation des eaux de pluie reçues sur la toile 54 de l'élément de toiture 52.Furthermore, the central mast 56 is preferably a hollow tube connected in the lower part to a rainwater drainage device (not shown). In addition, this central mast 56 includes an orifice (not shown) adapted to cooperate with the rainwater collector 55 to discharge to said rainwater evacuation device received on the fabric 54 of the roof element 52.

Les moyens de liaison 57 sont en outre agencés pour recevoir le bord périphérique intérieur de la toile 54. Pour cela, ces moyens de liaison 57 sont analogues aux moyens de liaison décrits dans la demande de brevet européen EP 1 905 926 déposée au de la demanderesse.The connecting means 57 are furthermore arranged to receive the inner peripheral edge of the fabric 54. For this purpose, these connecting means 57 are analogous to the connection means described in the European patent application. EP 1,905,926 filed at the plaintiff's.

Ainsi, en référence avec la figure 9, la toile 54 comporte le long de son bord périphérique intérieur un jonc 541, c'est-à-dire un bourrelet. Ce jonc 541 est formé par un anneau pris dans un pli de ladite toile 54, ledit anneau étant par exemple réalisé en corde naturelle ou synthétique.So, with reference to the figure 9 , the fabric 54 comprises along its inner peripheral edge a ring 541, that is to say a bead. This ring 541 is formed by a ring taken in a fold of said cloth 54, said ring being for example made of natural or synthetic rope.

Les moyens de liaison 57 comportent une cerce 571, c'est-à-dire une partie annulaire, destinée à recevoir sur sa face extérieure le jonc 541 de la toile 54. Cette cerce 571 est pourvue à sa extrémité supérieure d'une butée 572 s'étendant radialement vers l'extérieur, fixée à la cerce 571 par exemple par soudage, et un anneau de blocage 573 qui, dans la position où la toile 54 est montée, est interposé entre le jonc 541 et la butée 573 assurant ainsi le blocage du jonc 541.The connection means 57 comprise a ring 571, that is to say an annular part, intended to receive on its outer face the ring 541 of the fabric 54. This ring 571 is provided at its upper end with a stop 572 extending radially outwards, fixed to the ring 571 for example by welding, and a locking ring 573 which, in the position where the fabric 54 is mounted, is interposed between the rod 541 and the stop 573 thus ensuring the locking of the rod 541.

Par ailleurs, les moyens de liaison 57 comportent également une virole 574 de préférence cylindrique permettant le coulissement desdits moyens de liaisons 57 le long du mât central 56 et des moyens de jonction 575 reliant la virole 574 à la cerce 571, ces moyens de jonction 575 étant, par exemple, sous forme d'une pluralité d'ailes radiales.Furthermore, the connecting means 57 also comprise a preferably cylindrical sleeve 574 for sliding said connecting means 57 along the central mast 56 and connecting means 575 connecting the shell 574 to the core 571, these connecting means 575 being, for example, in the form of a plurality of radial wings.

Pour faciliter sa mise en place sur le mât central 56, en référence aux figures 6 à 8, la bride 59, qui est de préférence un élément tubulaire de type virole monté coulissant sur le mât central 56, comporte des moyens de verrouillage rapide 60. Ces derniers sont avantageusement de type à encliquetage et comprennent au moins un orifice 601 radial situé sur l'élément tubulaire de la bride 59, au moins un logement 602 tubulaire avantageusement cylindrique solidaire de la bride 59 et s'étendant radialement vers l'extérieur de la bride 59 au droit de l'orifice 601, une butée 603 située à l'extrémité libre dudit logement 602, un organe de poussée 604 de préférence de type ressort hélicoïdal contenu dans le logement 602 et prenant appui sur la butée 603, et un élément mobile 605 traversant en partie l'orifice 601 et agencé pour se déplacer dans le logement 602 sous l'action de l'organe de poussée 604 depuis une "position coulissement" (voir les figures 6 et 7) où son extrémité 606 est en appui sur la face extérieure du mât central 56 jusqu'à une "position verrouillage" (voir la figure 8) où son extrémité 606 se trouve à l'intérieur de la face extérieure du mât central 56.To facilitate its implementation on the central mast 56, with reference to Figures 6 to 8 , the flange 59, which is preferably a ferrule-type tubular element slidably mounted on the central mast 56, comprises quick-locking means 60. These are advantageously snap-type and comprise at least one radial orifice 601 located on the tubular element of the flange 59, at least one preferably cylindrical housing 602 integral with the flange 59 and extending radially outwardly of the flange 59 to the right of the orifice 601, a stop 603 located at the end free of said housing 602, a thrust member 604 preferably helical spring contained in the housing 602 and bearing on the stop 603, and a movable member 605 partially through the orifice 601 and arranged to move in the housing 602 under the action of the push member 604 from a "sliding position" (see Figures 6 and 7 ) where its end 606 bears on the outer face of the central mast 56 to a "locking position" (see FIG. figure 8 where its end 606 lies inside the outer face of the central mast 56.

On désigne ici par "l'intérieur de la face extérieure du mât central 56" la position dans laquelle l'extrémité 606 de l'élément mobile 605 a traversé réellement ou en projection la face extérieure du mât central 56 en direction de l'intérieur dudit mât central 56.Here, the term "inside the outer face of the central mast 56" designates the position in which the end 606 of the movable member 605 has actually passed through or in projection the outer face of the central mast 56 towards the inside. of said central mast 56.

Pour limiter sa course à l'intérieur du logement 602, l'élément mobile 605, qui est de préférence un cylindre, est muni d'une butée 607 étant avantageusement du type d'un épaulement venant en appui sur la face extérieure de la bride 59.To limit its stroke inside the housing 602, the movable member 605, which is preferably a cylinder, is provided with a stop 607 being advantageously of the type of a shoulder bearing on the outer face of the flange. 59.

Avec cette configuration des moyens de verrouillage rapide 60, dans la "position coulissement", la bride 59 peut coulisser le long du mât central 56 et, dans la "position verrouillage", la bride est bloquée à l'extrémité supérieure dudit mât central 56.With this configuration of the rapid locking means 60, in the "sliding position", the flange 59 can slide along the central mast 56 and, in the "locked position", the flange is locked at the upper end of said central mast 56 .

Avantageusement, dans la "position verrouillage" l'élément mobile 605 vient en appui sur la face annulaire de l'extrémité supérieure du mât central 56 (voir la figure 8). Cette "position verrouillage" est parfaitement sécurisée car, d'une part, la bride 59 a une longueur suffisante pour éviter son désengagement de l'extrémité du mât central 56 et, d'autre part, les câbles 58 de l'ensemble support 51 vont exercer sur ladite bride 59 un effort de traction vers le bas de sorte à maintenir l'élément mobile 605 en appui sur la face annulaire de l'extrémité supérieure du mât central 56 et donc maintenir la bride 59 verrouillée sur ledit mât central 56.Advantageously, in the "locking position" the movable member 605 bears on the annular face of the upper end of the central mast 56 (see FIG. figure 8 ). This "locking position" is perfectly secure because, on the one hand, the flange 59 has a length sufficient to prevent its disengagement from the end of the central mast 56 and, on the other hand, the cables 58 of the support assembly 51 will exert on said flange 59 a pulling force downwards so as to keep the movable member 605 bearing on the annular face of the upper end of the central mast 56 and thus maintain the flange 59 locked on said central mast 56.

Dans un mode préférentiel de réalisation, les moyens de verrouillage rapide 60 comportent trois orifices 601 disposés dans un même plan radial sur la bride 59 et dont les axes font un angle de 120° entre eux, et trois ensembles "logement 602-butée 603-organe de poussée 604-élément mobile 605".In a preferred embodiment, the rapid locking means 60 comprise three orifices 601 disposed in the same radial plane on the flange 59 and whose axes make an angle of 120 ° between them, and three assemblies "housing 602-stop 603-pushing member 604-moving member 605".

Conformément à l'invention, l'abri léger 50 comporte également un élément de toiture 52 comportant un cadre 53 disposé autour du mât central 56 de l'ensemble support 51, constitué de longeron 531 assemblés les uns aux autres, ayant une forme globale de polygone régulier et étant suspendu par les câbles 58 de l'ensemble support 51 reliés uniquement à chacun des sommets dudit cadre 53 afin de limiter les porte-à-faux. Pour des raisons d'équilibre mécanique, le cadre 53 aura avantageusement un nombre pair de sommets au minimum égal à six.According to the invention, the light shelter 50 also comprises a roof element 52 comprising a frame 53 disposed around the central mast 56 of the support assembly 51, consisting of a beam 531 assembled to each other, having a global shape of regular polygon and being suspended by the cables 58 of the support assembly 51 connected only to each of the vertices of said frame 53 to limit the overhangs. For reasons of mechanical balance, the frame 53 will advantageously have an even number of vertices at least equal to six.

Dans un mode préférentiel de réalisation, le cadre 53 a une forme d'hexagone régulier.In a preferred embodiment, the frame 53 has a regular hexagon shape.

De ce fait, tous les câbles 58 sont de longueur identique limitant ainsi le nombre de pièces différentes à approvisionner pour réaliser ledit abri léger 50.As a result, all the cables 58 are of identical length thus limiting the number of different parts to be supplied to make said light shelter 50.

Par ailleurs, afin de diminuer les dimensions de la section des éléments profilés et donc leur poids et leur coût, les longerons 531, notamment ceux de grande longueur, comportent chacun un moyen de précontrainte 61 (voir le détail de la figure 4) permettant de mettre chaque longeron 531 en état de tension, ladite tension est opposée à celle qui sera exercée par la toile 54 lorsque cette dernière sera tendue.Furthermore, in order to reduce the dimensions of the section of the profiled elements and therefore their weight and cost, the longitudinal members 531, in particular those of great length, each comprise a prestressing means 61 (see the detail of the figure 4 ) to put each beam 531 in tension, said tension is opposite to that which will be exerted by the web 54 when the latter will be tensioned.

Ainsi, ce moyen de précontrainte 61 est positionné au voisinage du milieu de chaque longeron 531 et comporte, de préférence, un câble 611 dont la longueur est sensiblement plus longue que celle dudit longeron 31 et dont les extrémités sont fixées respectivement à proximité des extrémités dudit longeron 531. Le moyen de précontrainte 61 comporte également un organe de contrainte 612 extensible s'étendant globalement perpendiculairement au longeron 531, apte à recevoir le câble 611 et de le mettre sous tension, à la manière de la corde d'un arc sur laquelle on tire radialement par rapport au manche de l'arc. Cette opération va tendre à repousser le milieu du longeron 531 vers l'extérieur du cadre 53 et permettre de résister à la tension de la toile 54 qui, au contraire, a pour effet de ramener ledit milieu du longeron 531 vers l'intérieur du cadre 53.Thus, this pre-stressing means 61 is positioned in the vicinity of the middle of each spar 531 and preferably comprises a cable 611 whose length is substantially longer than that of said spar 31 and whose ends are respectively fixed close to the ends of said spar. The prestressing means 61 also comprises an extensible stretcher member 612 extending generally perpendicularly to the spar 531, able to receive the cable 611 and to turn it on, in the manner of the string of an arc on which one draws radially with respect to the handle of the arc. This operation will tend to push the middle of the spar 531 towards the outside of the frame 53 and to withstand the tension of the fabric 54 which, on the contrary, has the effect of returning said middle of the spar 531 towards the inside of the frame 53.

Pour cela, l'organe de contrainte 612 est incliné de sorte à être sensiblement parallèle à la toile 54 tendue, et comprend un tube 613 solidaire du longeron 531 et comportant à son extrémité libre un taraudage (non représenté), une tige filetée 614 apte à se déplacer dans le tube 613 en coopérant avec ledit taraudage, un organe de réception 615 en forme générale de U, fixé à l'extrémité libre de ladite tige filetée 614 et apte à recevoir le câble 611, et un organe de blocage 616, avantageusement un écrou, permettant d'immobiliser la tige filetée 614 par rapport au tube 613.For this, the constraining member 612 is inclined so as to be substantially parallel to the stretched fabric 54, and comprises a tube 613 secured to the spar 531 and having at its free end a tapping (not shown), a threaded rod 614 fit to move in the tube 613 cooperating with said tapping, a U-shaped receiving member 615, fixed to the free end of said threaded rod 614 and adapted to receive the cable 611, and a locking member 616, advantageously a nut, for immobilizing the threaded rod 614 with respect to the tube 613.

Par ailleurs, le cadre 53 comporte un dispositif de fixation (non représenté) apte à assurer la solidarisation du bord périphérique extérieur de la toile 54 sur ledit cadre 53. Pour ce faire, le dispositif de fixation est avantageusement semblable à celui décrit dans le brevet européen EP 0 277 073 délivré au nom de la demanderesse.Furthermore, the frame 53 comprises a fastening device (not shown) capable of securing the external peripheral edge of the cloth 54 to said frame 53. To do this, the fastening device is advantageously similar to that described in the patent. European EP 0 277 073 issued in the name of the plaintiff.

Ainsi, le dispositif de fixation est tel que chacun des longerons 531 du cadre 53 présente une gorge débouchant par une fente d'entrée de largeur inférieure à celle du fond de la gorge et qu'un jonc de verrouillage peut être engagé transversalement dans la gorge, à travers sa fente d'entrée, et y être immobilisé pour y retenir le bord périphérique extérieur de la toile 54 présentant un bourrelet. Le dispositif de fixation est remarquable en ce qu'en position de verrouillage le jonc de verrouillage est en position verticale, à angle droit par rapport à sa position d'introduction par une fente d'entrée, et il est coincé à l'intérieur de la gorge, de sorte qu'un effort de traction exercé vers l'extérieur, sur la toile 54, ne permette pas au bourrelet de ladite toile 54 de s'échapper de la gorge.Thus, the fixing device is such that each of the longitudinal members 531 of the frame 53 has a groove opening through an inlet slot of width less than that of the bottom of the groove and that a locking ring can be engaged transversely in the throat , through its entrance slot, and be immobilized there to retain the outer peripheral edge of the web 54 having a bead. The fixing device is remarkable in that in the locking position the locking ring is in the vertical position, at right angles to its insertion position by an entrance slot, and it is stuck inside the groove, so that a tensile force exerted outwardly on the fabric 54, does not allow the bead of said fabric 54 to escape from the groove.

Pour plus de détails concernant ledit dispositif de fixation, on se référera audit brevet européen EP 0 277 073 .For more details concerning said fixing device, reference will be made to said European patent EP 0 277 073 .

Enfin, en référence avec les figures 10 et 11, pour faciliter la mise en place de la toile 54 sur le cadre 53, notamment lorsque l'ensemble support 51 est érigé, la toile 54 présente une coupe 542 joignant son bord périphérique intérieur fixé sur les moyens de liaison 57 à son bord périphérique extérieur fixé sur ledit cadre 53 et un organe de jonction 62 apte à coopérer avec les bords de ladite coupe 542 pour les relier ensemble et former une surface continue autour de l'ensemble support 51 en fermant les bords périphériques intérieur et extérieur de la toile 54. Cet organe de jonction 62 est un profilé dont la longueur est sensiblement égale à celle de la coupe 542 et ayant une section en forme générale de H dont les extrémités libres 621 se replient légèrement sur elles-mêmes de manière à former deux logements 622 aptes à recevoir lesdits bords de la coupe 542 présentant chacun un bourrelet 543 (voir la figure 11). Pour mettre en place l'organe de jonction 62, il faut engager simultanément, de préférence, l'une des extrémités des deux bourrelets 543 dans les logements 622 dudit organe de jonction 62 et faire glisser ledit organe de jonction 62 jusqu'aux autres extrémités desdits bourrelets 543 de le toile 54 afin d'obtenir une toile 54 montée présentant l'aspect illustré sur la figure 10.Finally, with reference to Figures 10 and 11 , to facilitate the placement of the fabric 54 on the frame 53, especially when the support assembly 51 is erected, the fabric 54 has a section 542 joining its inner peripheral edge fixed on the connecting means 57 at its outer peripheral edge fixed on said frame 53 and a connecting member 62 adapted to cooperate with the edges of said cut 542 to connect them together and form a continuous surface around the support assembly 51 by closing the inner and outer peripheral edges of the fabric 54. This joining member 62 is a profile whose length is substantially equal to that of the section 542 and having a generally H-shaped section whose free ends 621 fold slightly on themselves so as to form two housings 622 capable of receiving said edges of the cup 542 each having a bead 543 (see FIG. figure 11 ). To set up the junction member 62, it is necessary to engage simultaneously, preferably, one of the ends of the two beads 543 in the housings 622 of said connecting member 62 and to slide said connecting member 62 to the other ends said beads 543 of the fabric 54 to obtain a web 54 mounted having the appearance illustrated on the figure 10 .

On comprend bien que cet organe de jonction 62 est intéressant car il permet de mettre la toile 54 en place autour de l'ensemble support 51 après avoir érigé ledit ensemble support 51, afin d'éviter que la toile 54 reste au sol durant le montage dudit ensemble support 51 et ne soit salie ou pire détériorée.It is understood that this connecting member 62 is interesting because it allows to put the fabric 54 in place around the support assembly 51 after having erected said support assembly 51, to prevent the fabric 54 remains at during installation of said support assembly 51 and is dirty or worse deteriorated.

La présente invention a également pour objet le procédé de montage dudit abri léger 50. Ce montage se déroule de la manière suivante.The present invention also relates to the method of mounting said light shelter 50. This assembly proceeds in the following manner.

La toile 54 est posée sur le sol de sorte que le massif devant recevoir le mât central 56 de l'ensemble support 51 apparaisse dans l'orifice de la toile 54.The fabric 54 is placed on the ground so that the mass to receive the central mast 56 of the support assembly 51 appears in the orifice of the fabric 54.

Cette étape peut avantageusement être réalisée après l'assemblage du cadre 53, comme représenté sur les figures 3 et 4, afin d'éviter que la toile ne soit salie ou pire détériorée. Pour cela, il faudra prévoir une étape de mise en place de l'organe de jonction 62, précédemment décrit, sur la toile 54.This step can advantageously be carried out after the assembly of the frame 53, as shown in FIGS. Figures 3 and 4 , to avoid that the canvas is dirty or worse deteriorated. For this, it will be necessary to provide a step of placing the connecting member 62, previously described, on the fabric 54.

L'ensemble support 51 est érigé en mettant en place le mât central 56 sur le massif, au préalable les moyens de liaison 57 et la bride 59 sont montés coulissants sur ledit mât central 56, les câbles 58 étant fixés à l'une de leurs extrémités à la bride 59.The support assembly 51 is erected by placing the central mast 56 on the solid mass, before the connecting means 57 and the flange 59 are slidably mounted on said central mast 56, the cables 58 being attached to one of their ends at the flange 59.

On notera que pour cette étape d'érection de l'ensemble support 51, il n'est pas nécessaire de recourir à une grue. L'utilisation d'un mât de levage est également intéressante en ce que sa hauteur peut être égale, voire inférieure, à celle de l'ensemble support 51, de sorte que l'abri léger peut être monté même dans des endroits où la hauteur libre au-dessus de l'abri léger est faible.Note that for this erection stage of the support assembly 51, it is not necessary to resort to a crane. The use of a lifting mast is also advantageous in that its height may be equal to or even less than that of the support assembly 51, so that the lightweight shelter can be mounted even in places where the height free over the light shelter is weak.

L'étape suivante consiste à assembler et à mettre en place le cadre 53 autour dudit ensemble support 51, comme représenté sur la figure 3. Pour cette opération, on apporte les éléments du cadre 53 formés de longerons 531. Ces derniers sont posés sur des tréteaux 63 et le cadre 53 est monté sur place par fixation (par exemple par boulonnage) des extrémités de longerons 531 entre elles. Par ailleurs, au fur et à mesure de l'assemblage du cadre 53, un moyen de précontrainte 61 pourra être mis en place sur chaque longeron 531 dudit cadre 53, notamment pour les cadres 53 de grandes dimensions.The next step is to assemble and set up the frame 53 around said support assembly 51, as shown in FIG. figure 3 . For this operation, the elements of the frame 53 are provided formed of longitudinal members 531. These are placed on trestles 63 and the frame 53 is mounted on site by fixing (for example by bolting) the ends of longitudinal members 531 therebetween. Moreover, as and when assembly of the frame 53, prestressing means 61 may be placed on each spar 531 of said frame 53, in particular for frames 53 of large dimensions.

Comme représenté sur la figure 3, l'extrémité libre des câbles 58 est ensuite fixée aux points de fixation 532 du cadre 53 qui sont disposés au droit de chaque sommet du cadre 53.As shown on the figure 3 , the free end of the cables 58 is then fixed to the attachment points 532 of the frame 53 which are arranged at the right of each top of the frame 53.

L'ensemble "cadre 53-câbles 58-bride 59" est ensuite légèrement soulevé à l'aide d'un moyen de levage approprié tel qu'une grue dont le crochet est relié à ladite bride 59, de telle sorte qu'il soit maintenu à une hauteur suffisante pour permettre une mise en place aisée de la toile 54. Toutefois, cette dernière étape de levage intermédiaire est facultative car l'étape suivante peut être réalisée sans avoir à lever l'ensemble "cadre 53-câbles 58-bride 59".The assembly "frame 53-cables 58-flange 59" is then slightly raised using a suitable lifting means such as a crane whose hook is connected to said flange 59, so that it is maintained at a height sufficient to allow easy installation of the fabric 54. However, this last step of intermediate lifting is optional because the next step can be performed without having to lift the assembly "frame 53-cables 58-flange 59 ".

Après avoir retiré les tréteaux 63, comme représenté sur la figure 4, la toile 54 est fixée de façon sensiblement étanche, d'une part, sur les moyens de liaison 57 par son bord périphérique intérieur conformément à ce qui a été décrit précédemment et, d'autre part, sur le cadre 53 par son bord périphérique extérieur. La toile 54 peut être fixée sur le cadre 53 par tout moyen connu et notamment collage, soudage, clipsage ou par un dispositif de fixation semblable à celui décrit dans le brevet européen EP 0 277 073 , comme précédemment décrit. A ce stade, la toile 54 n'est pas encore tendue.After removing the trestles 63, as shown in FIG. figure 4 , the fabric 54 is fixed substantially sealingly, on the one hand, on the connecting means 57 by its inner peripheral edge in accordance with what has been previously described and, on the other hand, on the frame 53 by its peripheral edge outside. The fabric 54 may be fixed to the frame 53 by any known means and in particular gluing, welding, clipping or by a fixing device similar to that described in the European patent EP 0 277 073 as previously described. At this point, the fabric 54 is not yet stretched.

Ensuite, on continue à lever l'ensemble "cadre 53-câbles 58-bride 59" en tirant la bride 59 vers le haut jusqu'à sa "position verrouillage" où, comme décrit précédemment, les éléments mobiles 605 des moyens de verrouillage rapide 60 viennent en appui sur la face annulaire de l'extrémité supérieure du mât central 56 (voir les figures 4, 5 et 8).Then, we continue to lift the assembly "frame 53-cables 58-flange 59" by pulling the flange 59 up to its "locking position" where, as described above, the movable elements 605 of the rapid locking means 60 bear on the annular face of the upper end of the central mast 56 (see Figures 4, 5 and 8 ).

Ensuite, il faut mettre la toile 54 sous tension. Pour cela, il suffit de tirer les moyens de liaison 57 vers le bas jusqu'à obtenir la tension souhaitée de la toile 54. Ceci peut être réalisé simplement, comme représenté sur la figure 5, en solidarisant un tire-câble 64 à main par exemple de type TIRFOR (Marque déposée) sur l'extrémité inférieure du mât central 56 et en reliant les moyens de liaison 57 au tire-câble 64 par un câble 65 (voir figure 5).Then, it is necessary to put the fabric 54 under tension. For this, it is sufficient to pull the connecting means 57 down to obtain the desired tension of the fabric 54. This can be done simply, as shown in FIG. figure 5 , by joining a hand-held cable puller 64 of the TIRFOR type (registered trademark) on the lower end of the central mast 56 and connecting the connection means 57 to the cable puller 64 by a cable 65 (see FIG. figure 5 ).

Une fois la toile 54 tendue correctement, les moyens de liaison 57 sont verrouillés en position sur le mât central 56 à l'aide, par exemple d'un axe 66 traversant simultanément les moyens de liaison 57 et le mât central 56.Once the fabric 54 has stretched correctly, the connecting means 57 are locked in position on the central mast 56 by means of, for example, an axis 66 traversing simultaneously the connecting means 57 and the central mast 56.

Le montage de l'abri léger 50 est maintenant quasiment terminé. On peut alors retirer le tire-câble 64 de l'ensemble support 51 et mettre en place le collecteur d'eau pluviale 55 sur le mât central 56 autour des moyens de liaison 57. L'abri léger 50 monté présente alors l'aspect illustré sur la figure 2.The assembly of the light shelter 50 is now almost finished. The cable puller 64 can then be removed from the support assembly 51 and the rainwater collector 55 is put in place on the central mast 56 around the connecting means 57. The light shelter 50 mounted then has the appearance illustrated. on the figure 2 .

On comprend bien que les étapes précédemment décrites peuvent ne pas être exécutées dans l'ordre indiqué. Par exemple, la fixation de la toile 54 peut être réalisée avant de fixer l'extrémité libre des câbles 58 aux points de fixation 532 du cadre 53.It is understood that the previously described steps may not be executed in the order indicated. For example, the fixing of the fabric 54 can be performed before fixing the free end of the cables 58 to the attachment points 532 of the frame 53.

De même, on comprend bien que ce montage pourra comporter une étape de réalisation d'un massif en béton avant d'ériger l'ensemble support 51.Similarly, it is clear that this assembly may include a step of producing a concrete block before erecting the support assembly 51.

On notera encore que ce montage comporte peu d'étapes et qu'il est particulièrement simple et rapide à mettre en oeuvre.It should be noted that this assembly has few steps and that it is particularly simple and quick to implement.

En référence aux figures 14 et 15, l'invention concerne également un auvent modulaire 100 constitué d'une pluralité d'abris légers 50, de dimensions différentes ou non, disposés les uns à côté des autres.With reference to Figures 14 and 15 the invention also relates to a modular awning 100 consisting of a plurality of light shelters 50, of different dimensions or not, arranged next to each other.

On a représenté sur la figure 14 plusieurs exemples d'agencement d'auvent modulaire 100 non limitatifs de l'invention.We have shown on the figure 14 several examples of non-limiting modular awning arrangement 100 of the invention.

Pour obtenir ledit auvent modulaire 100, il faut assembler, comme décrit précédemment, chacun des abris légers 50 constituant l'auvent modulaire 100 et les disposer les uns à côté des autres de sorte qu'un abri léger 50 comporte au moins un longeron 531 en vis-à-vis avec un longeron 531 d'au moins un abri léger 50 adjacent, les longerons 531 en vis-à-vis étant proches ou en contact.To obtain said modular awning 100, it is necessary to assemble, as previously described, each of the light shelters 50 constituting the modular awning 100 and arrange them next to each other so that a light shelter 50 comprises at least one spar 531. vis-à-vis with a spar 531 of at least one light shelter 50 adjacent, the rails 531 vis-à-vis being close or in contact.

On comprend bien que pour obtenir un auvent modulaire 100 sensiblement étanche, il est nécessaire d'assurer l'étanchéité entre les différents abris légers 50 constituant ledit auvent modulaire 100.It is understood that to obtain a modular awning 100 substantially sealed, it is necessary to seal between the various light shelters 50 constituting said modular awning 100.

Pour cela, en référence à la figure 15, l'auvent modulaire 100 comporte un dispositif d'étanchéité 101 entre les longerons 531 en vis-à-vis des cadres 53 de deux abris légers 50 adjacents.For this, with reference to the figure 15 , the modular awning 100 comprises a sealing device 101 between the longitudinal members 531 vis-à-vis the frames 53 of two adjacent lightweight shelters 50.

Le dispositif d'étanchéité 101 comprend un premier organe d'étanchéité 102 fixé sur le dessus d'un des deux longerons 531 en vis-à-vis et un deuxième organe d'étanchéité 103 fixé sur le dessus de l'autre longeron 531, les premier et deuxième organes d'étanchéité 102, 103 étant fixés de façon sensiblement étanche sur le dessus desdits longerons 531 et aptes à coopérer ensemble pour créer un chicane permettant d'éviter une entrée d'eau de pluie entre les deux longerons 531 en vis-à-vis.The sealing device 101 comprises a first sealing member 102 fixed on top of one of the two longitudinal members 531 facing each other and a second sealing member 103 fixed on top of the other longitudinal member 531, the first and second sealing members 102, 103 being substantially sealingly attached to the top of said longitudinal members 531 and capable of cooperating together to create a baffle preventing a rainwater inlet between the two longitudinal members 531 -a-vis.

Pour cela, le premier organe d'étanchéité 102 est une cornière comportant une première aile 104 en contact avec le dessus du longeron 531 sur lequel il est fixé et une deuxième aile 105 s'étendant sensiblement perpendiculairement depuis le dessus dudit longeron 531 vers le haut.For this, the first sealing member 102 is an angle having a first flange 104 in contact with the top of the spar 531 on which it is fixed and a second flange 105 extending substantially perpendicularly from above the spar 531 upwards. .

Par ailleurs, le deuxième organe d'étanchéité 103 est un profilé dont la section verticale a une forme générale de Z comportant une première aile 106 en contact avec le dessus du longeron 531 sur lequel il est fixé, une deuxième aile 107 s'étendant sensiblement perpendiculairement depuis le dessus dudit longeron 531 vers le haut et une troisième aile 108 s'étendant sensiblement parallèlement au dessus dudit longeron 531 et munie le long de son bord libre d'un retour 109 s'étendant sensiblement perpendiculairement depuis le dessous de ladite troisième aile 108 vers le bas.Furthermore, the second sealing member 103 is a profile whose vertical section has a general Z-shape with a first flange 106 in contact with the top of the spar 531 on which it is fixed, a second flange 107 extending substantially perpendicularly from the top of said spar 531 upwards and a third flange 108 extending substantially parallel to the top of said spar 531 and provided along its free edge with a return 109 extending substantially perpendicularly from below said third wing 108 down.

Lorsque le dispositif d'étanchéité 101 est en place le long de deux longerons 531 en vis-à-vis, les deuxième aile 107, troisième aile 108 et retour 109 du deuxième organe d'étanchéité 103 recouvrent en partie la deuxième aile 105 du premier organe d'étanchéité 102 de sorte à créer la chicane.When the sealing device 101 is in place along two longitudinal members 531 facing each other, the second flanges 107, third flange 108 and return 109 of the second sealing member 103 partly cover the second flange 105 of the first sealing member 102 so as to create the baffle.

Enfin, l'invention a aussi pour objet le procédé de montage de l'auvent modulaire 100 selon l'invention comportant une pluralité d'étapes à savoir :

  • montage des différents abris légers 50 constituant l'auvent modulaire 100,
  • mise en place du dispositif d'étanchéité 101 entre les longerons 531 en vis-à-vis des cadres 53 de deux abris légers 50 adjacents.
Finally, the invention also relates to the method of mounting the modular awning 100 according to the invention comprising a plurality of steps namely:
  • assembly of the various light shelters 50 constituting the modular awning 100,
  • installation of the sealing device 101 between the longitudinal members 531 opposite the frames 53 of two adjacent lightweight shelters 50.

De plus, on comprend bien que ce montage pourra comporter une étape de réalisation d'un massif en béton avant de montage des différents abris légers 50.In addition, it is clear that this assembly may include a step of producing a concrete block before mounting various light shelters 50.

Description d'autres modes de réalisationDescription of other embodiments

Dans une variante de réalisation représentée sur les figures 12 et 13, l'abri léger 50 comporte une second mode de réalisation du dispositif de fixation apte à assurer la solidarisation du bord périphérique extérieur de la toile 54 sur ledit cadre 53. Ainsi, ce dispositif de fixation comprend un lacet 67, avantageusement élastique, passant alternativement autour des longerons 531 du cadre 53 et dans des orifices 68 aménagés le long dudit bord périphérique extérieur de la toile 54. Ce dispositif de fixation permet de fixer la toile 54 sur le cadre 53 mais d'également d'assurer partiellement ou en totalité la mise sous tension de la toile 54.In an alternative embodiment shown on the Figures 12 and 13 , the light shelter 50 comprises a second embodiment of the fastening device adapted to ensure the fastening of the outer peripheral edge of the cloth 54 on said frame 53. Thus, this device for fixation comprises a lace 67, advantageously elastic, passing alternately around the longitudinal members 531 of the frame 53 and in orifices 68 arranged along said outer peripheral edge of the fabric 54. This fixing device makes it possible to fix the fabric 54 to the frame 53 but also to ensure partially or completely the power of the canvas 54.

Dans une autre variante de réalisation non représentée, dans la "position verrouillage" les éléments mobiles 605 des moyens de verrouillage rapide 60 ne viennent pas en appui sur la face annulaire de l'extrémité supérieure du mât central 56 mais coopèrent chacun avec un orifice réalisé dans l'extrémité supérieure dudit mât central 56. Toutefois, cette configuration est peu avantageuse car elle nécessite un positionnement angulaire de la bride 59 lors de son montage.In another variant embodiment, not shown, in the "locking position", the mobile elements 605 of the quick-locking means 60 do not bear against the annular face of the upper end of the central mast 56, but each cooperate with an orifice made of in the upper end of said central mast 56. However, this configuration is disadvantageous because it requires an angular positioning of the flange 59 during its assembly.

Lesdits éléments mobiles 605 pourront également coopérer avec une rainure périmétrique réalisée à l'extrémité supérieure dudit mât central 56 sans sortir du cadre de la présente invention.Said movable elements 605 may also cooperate with a perimeter groove made at the upper end of said central mast 56 without departing from the scope of the present invention.

Dans une autre variante de réalisation non représentée, le cadre 53 de l'élément de toiture 52 de l'abri léger 50 n'a pas une forme d'hexagone mais a une forme de polygone avantageusement régulier comportant 8, 10, 12 ou 14 sommets.In another variant embodiment, not shown, the frame 53 of the roof element 52 of the light shelter 50 does not have a hexagon shape but has a shape advantageously regular polygon having 8, 10, 12 or 14 highs.

Ledit cadre 53 pourra également avoir une forme de polygone avec un nombre impair de sommets et au moins égal à 5, sans sortir du cadre de la présente invention. Toutefois, dans cette configuration, les câbles 58 ne seront pas disposés symétriquement deux à deux par rapport à l'axe du mât central 56 de l'ensemble support 51.Said frame 53 may also have a polygon shape with an odd number of vertices and at least equal to 5, without departing from the scope of the present invention. However, in this configuration, the cables 58 will not be arranged symmetrically two by two with respect to the axis of the central mast 56 of the support assembly 51.

Ledit cadre 53 pourra également avoir une forme de polygone avec un nombre important de sommets de sorte à tendre vers une forme circulaire sans sortir du cadre de la présente invention.Said frame 53 may also have a polygon shape with a large number of vertices so as to tend towards a circular shape without departing from the scope of the present invention.

Toutefois, ces différentes configurations accroissent le nombre de pièces (longerons et câbles) et par conséquent le temps de montage. En outre, les configurations de cadres 53 avec un nombre important de sommets ne permettent pas de juxtaposer des abris légers 50 pour former un auvent modulaire 100. La forme hexagonale reste le bon compromis entre résistance mécanique, temps de montage réduit et juxtaposabilité.However, these different configurations increase the number of parts (spars and cables) and therefore the assembly time. In addition, the configurations of frames 53 with a large number of vertices do not allow to juxtapose light shelters 50 to form a modular awning 100. The hexagonal shape remains the right compromise between mechanical strength, reduced assembly time and juxtaposition.

Enfin, le dispositif d'étanchéité 101 entre les longerons 531 en vis-à-vis des cadres 53 de deux abris légers 50 adjacents pourra être un simple profilé en forme de U (non représenté) sans sortir du cadre de la présente invention. Ce profilé en U aura une âme reposant sur le dessus des deux longerons 531 en vis-à-vis et dont la largeur sera supérieure à celle desdits longerons 531, et deux ailes légèrement évasées orientées vers le bas. Ce profilé en U chapeautera les deux longerons 531 et interdira une entrée d'eau de pluie entre les deux longerons 531 en vis-à-vis.Finally, the sealing device 101 between the longitudinal members 531 opposite the frames 53 of two adjacent lightweight shelters 50 may be a simple U-shaped section (not shown) without departing from the scope of the present invention. This U-shaped profile will have a core resting on the top of the two longitudinal members 531 vis-à-vis and whose width will be greater than that of said longitudinal members 531, and two slightly flared wings oriented downwards. This U-shaped section will cover the two longerons 531 and prohibit a rainwater inlet between the two longitudinal members 531 vis-à-vis.

Dans une autre variante de réalisation non représentée, l'ensemble support, semblable à l'ensemble support 51 précédemment décrit, comporte un mât central télescopique. En effet, pour des raisons de transport, notamment pour une exportation dudit élément support en container maritime, il est intéressant que ce mât central soit télescopique. Pour ce faire, ledit mât central est formé d'au moins deux éléments mobiles en translation longitudinale l'un par rapport à l'autre. Avantageusement, le mât central ne comporte que deux éléments, le premier élément dit "inférieur" étant un tube creux destiné à être fixé sur un massif par des moyens de fixation adéquats, le second élément dit "supérieur" étant un tube creux apte à coulisser à l'intérieur dudit élément inférieur.In another variant embodiment not shown, the support assembly, similar to the support assembly 51 previously described, comprises a telescopic central mast. Indeed, for reasons of transport, in particular for an export of said support element in maritime container, it is interesting that the central mast is telescopic. To do this, said central mast is formed of at least two movable elements in longitudinal translation relative to each other. Advantageously, the central mast has only two elements, the first element called "lower" being a hollow tube intended to be fixed on a solid mass by suitable fastening means, the second element called "upper" being a hollow tube capable of sliding inside said lower element.

Une fois entièrement étendu, le mât central est verrouillé en position à l'aide, par exemple, d'un axe traversant simultanément lesdits deux éléments. Une fois le mât central verrouillé, la bride peut être montée coulissante sur ledit mât central ainsi que l'ensemble des éléments constitutifs de l'ensemble support selon le procédé décrit précédemment.Once fully extended, the central mast is locked in position using, for example, an axis traversing simultaneously said two elements. Once the central mast is locked, the flange can be slidably mounted on said central mast and all the components of the support assembly according to the method described above.

Enfin, dans une dernière variante de réalisation non représentée, l'ensemble support, semblable à l'ensemble support 51 précédemment décrit, comporte également un mât central télescopique comprenant un élément inférieur et au moins un élément supérieur coulissant à l'intérieur dudit élément inférieur qui est fixé sur un massif. Cet ensemble support comporte en outre une bride fixée à l'extrémité supérieure de l'élément supérieur. Ainsi, le montage coulissant de la bride sur le mât central est réalisé par le coulissement de l'ensemble (bride-élément supérieur) à l'intérieur dudit élément inférieur.Finally, in a last variant embodiment not shown, the support assembly, similar to the support assembly 51 previously described, also comprises a telescopic central mast comprising a lower element and at least one upper element sliding inside said lower element which is fixed on a massif. This support assembly further comprises a flange attached to the upper end of the upper member. Thus, the sliding mounting of the flange on the central mast is achieved by sliding the assembly (flange-upper element) inside said lower member.

On comprend bien que si le mât central comprend plus de deux éléments mobiles, la bride sera fixée sur l'élément supérieur qui est celui qui est disposé le plus en haut du mât central lorsque ce dernier est entièrement étendu.It is well understood that if the central mast comprises more than two movable elements, the flange will be fixed on the upper element which is the one which is arranged at the top of the central mast when the latter is fully extended.

Possibilité d'application industriellePossibility of industrial application

L'élément support 51 d'un élément de toiture 52 selon l'invention et l'abri léger 50 comportant un tel élément support 51 peuvent avantageusement être installés sur tout type de site quelles que soient les conditions climatiques et d'accès. En outre, il ressort clairement de la description que la structure de l'abri léger 50 selon l'invention est de construction légère, simple et rapide, tout en garantissant une tenue mécanique remarquable.The support element 51 of a roof element 52 according to the invention and the light shelter 50 comprising such a support element 51 can advantageously be installed on any type of site whatever the climatic conditions and access.
