Description

La présente invention a pour objet une barrière métallique, notamment pour l'équipement de voies de circulation routière. Les ponts et autres passages aériens doivent être équipés de barrières formant garde-corps dans la mesure où ils permettent non seulement la circulation de véhicules mais également le passage de piétons. Dans la mesure où une telle barrière doit servir à la retenue éventuelle d'un véhicule, elle doit répondre à des critères très strictes de résistance aux chocs. Des barrières sont également très souvent utilisées dans des lieux publics ou privés, par exemple au bord de terrasses pour assurer la protection des personnes.The present invention relates to a metal barrier, in particular for equipping road traffic lanes. Bridges and other overhead passages must be fitted with barriers forming a railing insofar as they allow not only the movement of vehicles but also the passage of pedestrians. Insofar as such a barrier must serve for the possible restraint of a vehicle, it must meet very strict criteria of impact resistance. Barriers are also very often used in public or private places, for example at the edge of terraces to ensure the protection of people.

Une barrière traditionnelle comprend des poteaux fixés au sol à intervalles réguliers, portant des lisses parallèles entre elles dont le nombre est fonction de la hauteur du garde-corps. Chaque poteau comprend une platine de fixation au sol et un corps de poteau sur la face avant duquel sont fixées les lisses. Le plus souvent le poteau est réalisé en plusieurs parties soudées les unes aux autres, et la platine inférieure est indépendante du corps du poteau et fixée sur celui-ci par soudage. Outre le fait que ce type de fabrication nécessite un nombre important d'opérations successives et est par conséquent très onéreux de mise en oeuvre, une telle barrière ne présente pas de parfaites garanties de sécurité, du fait qu'en cas de choc le couple de basculement exercé sur un poteau se traduit parfois par la désolidarisation de celui-ci de la platine qui demeure pour sa part fixée au sol.A traditional barrier includes posts fixed to the ground at regular intervals, carrying beams parallel to each other, the number of which depends on the height of the railing. Each post includes a ground fixing plate and a post body on the front face of which the beams are fixed. Most often the post is made of several parts welded to each other, and the lower plate is independent of the body of the post and fixed thereon by welding. In addition to the fact that this type of manufacturing requires a large number of successive operations and is therefore very expensive to implement, such a barrier does not offer perfect guarantees of safety, because in the event of an impact the torque of tilting exerted on a pole sometimes results in the separation of the latter from the plate which for its part remains fixed to the ground.

En outre, les poteaux de garde-corps présentent le plus souvent une forme spécifique à leur hauteur, de telle sorte qu'il n'est pas possible de fixer une même lisse sur des poteaux de tailles différentes, si l'utilisation de poteaux de tailles différentes est rendue nécessaire par exemple en raison d'une dénivellation du terrain.In addition, the railing posts most often have a specific shape at their height, so that it is not possible to fix the same beam on posts of different sizes, if the use of posts different sizes is made necessary for example due to a slope of the ground.

La présente invention vise à remédier à ces inconvénients.The present invention aims to remedy these drawbacks.

A cet effet, dans la barrière qu'elle concerne, chaque poteau comprend en combinaison une plaque métallique pliée de façon à former une face avant plane destinée au support des lisses, et un retour inférieur constituant la semelle de fixation au sol, et un profilé de section en U, de hauteur correspondant à celle du poteau et dont l'écartement des ailes du U est inférieur à la largeur de la plaque formant la face avant et la semelle, ce profilé métallique étant fixé sur la plaque par soudage sur sa face avant et sa semelle.To this end, in the barrier which it concerns, each post comprises in combination a metal plate folded so as to form a flat front face intended for the support of the beams, and a lower return constituting the sole for fixing to the ground, and a profile. U-shaped section, height corresponding to that of the post and the spacing of the wings of the U is less than the width of the plate forming the front face and the sole, this metal profile being fixed on the plate by welding on its front and sole.

Cette barrière présente l'avantage que les poteaux sont très simples à réaliser puisque constitués par deux éléments métalliques fixés l'un sur l'autre par soudage, l'élément profilé assurant le raidissement de la plaque formant la face avant et la semelle. En pratique ce poteau est extrêmement sûr puisque, compte tenu de sa structure, la platine de fixation au sol ne peut en aucun cas être désolidarisée de sa face avant. En outre, sa face avant n'est absolument pas dangereuse ni agressive pour un corps projeté ou pour les pneumatiques des véhicules, puisqu'elle ne comporte pas de parties de cigidification en saillie vers l'avant comme tel est le cas dans certains poteaux traditionnels. Enfin, le montage des lisses est effectué de façon très simple puisque la fixation de celles-ci intervient au niveau de perçages ménagés dans la face avant de la plaque métallique principale de part et d'autre du profilé en U ce qui rend l'accès aux moyens de fixation extrêmement aisé.This barrier has the advantage that the posts are very simple to produce since they consist of two metal elements fixed to one another by welding, the profiled element ensuring the stiffening of the plate forming the front face and the sole. In practice, this post is extremely safe since, given its structure, the ground fixing plate cannot in any case be detached from its front face. In addition, its front face is absolutely not dangerous or aggressive for a projected body or for the tires of vehicles, since it does not include parts of cigidification projecting forward as is the case in some traditional posts . Finally, the assembly of the beams is carried out in a very simple way since the fixing of these intervenes at the level of bores made in the front face of the main metal plate on either side of the U-profile which makes access with extremely easy fixing means.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de cette barrière :

  • Figure 1 est une vue en perspective d'une barrière ;
  • Figure 2 à 4 sont trois vues de côté de trois types de poteaux mis en oeuvre pour la réalisation de la barrière de figure 1 ;
  • Figure 5 est une vue de la face arrière du poteau représenté à la figure 4 ;
  • Figure 6 est une vue de dessus du poteau de figure 2 ;
  • Figure 7 est une vue en coupe transversale représentant la liaison entre deux tronçons de lisses successifs ;
  • Figure 8 est une vue en coupe transversale représentant le mode de fixation d'une lisse sur un poteau.
In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing representing, by way of nonlimiting example, an embodiment of this barrier:
  • Figure 1 is a perspective view of a barrier;
  • Figure 2 to 4 are three side views of three types of posts used for the realization of the barrier of Figure 1;
  • Figure 5 is a view of the rear face of the post shown in Figure 4;
  • Figure 6 is a top view of the post of Figure 2;
  • Figure 7 is a cross-sectional view showing the connection between two successive heald sections;
  • Figure 8 is a cross-sectional view showing the method of fixing a heald on a post.

La barrière selon l'invention dont un tronçon (2) est représenté à la figure 1 comprend un certain nombre de poteaux (3a,3b,3c) supportant des lisses horizontales (4), dont le nombre est fonction de la hauteur des poteaux les supportant. Comme cela ressort de la figure 1, la barrière étant montée sur un mur (5) comportant plusieurs décrochements en hauteur, plusieurs types de poteaux de hauteurs différentes sont mis-en oeuvre, les poteaux (3a) étant de hauteur supérieure à celles des poteaux (3b) qui sont eux-mêmes de hauteur supérieure à celle des poteaux (3c). Toutefois la structure des différents types de poteaux est la même.The barrier according to the invention, a section (2) of which is shown in FIG. 1, comprises a number of posts (3a, 3b, 3c) supporting horizontal beams (4), the number of which depends on the height of the posts. supporting. As can be seen in FIG. 1, the barrier being mounted on a wall (5) comprising several recesses in height, several types of posts of different heights are used, the posts (3a) being of height greater than those of the posts (3b) which are themselves higher than that of the posts (3c). Any times the structure of the different types of posts is the same.

Chaque poteau est réalisé à partir de deux elements principaux, à savoir une plaque métallique (6) pliée de façon à former une face avant (7) plane et verticale, comportant deux retours (8) et (9) respectivement à son extrémité inférieure et à son extrémité supérieure.Each post is made from two main elements, namely a metal plate (6) folded so as to form a flat and vertical front face (7), comprising two returns (8) and (9) respectively at its lower end and at its upper end.

Avant ménagement du retour (8) la face avant comporte à proximité de son extrémité inférieure un décrochement vers l'extérieur formant un nez (10). Le second élément constitutif de ce poteau est un profilé métallique (12) en U dont la section augmente de haut en bas. Il est à noter que l'écartement entre les ailes du profilé en U est de largeur inférieur à la largeur de la plaque métallique, de telle sorte qu'elle ménage dans cette dernière deux zones latérales dans lesquelles se trouvent les trous (13) de fixation des lisses (4). Le profilé (12) est fixé par soudage en (14) le long de la face avant (7), ainsi que le long des retours (8 et 9) de la plaque métallique principale (6). Sur le profilé (12) sont fixés par soudage deux pattes (15) destinées à venir obturer les ouvertures latérales situées au niveau des deux décrochements (10). Afin d'augmenter la rigidité du poteau, le profilé en U présente sur chacune de ses branches deux plis nervurés (16) tournés vers l'extérieur. Le fait que le profilé (12) soit encastré entre les retours (8) et (9) de la plaque (6) évite tout risque de glissement du profilé par rapport à la plaque en cas de défaillance accidentelle des soudures.Before the return (8) is formed, the front face comprises, near its lower end, an outward recess forming a nose (10). The second component of this post is a U-shaped metal profile (12) whose section increases from top to bottom. It should be noted that the spacing between the wings of the U-shaped section is of width less than the width of the metal plate, so that it provides in the latter two lateral zones in which the holes (13) are located. heald fixing (4). The profile (12) is fixed by welding at (14) along the front face (7), as well as along the returns (8 and 9) of the main metal plate (6). On the profile (12) are fixed by welding two tabs (15) intended to close off the lateral openings located at the level of the two recesses (10). In order to increase the rigidity of the post, the U-shaped profile has on each of its branches two ribbed folds (16) facing outwards. The fact that the profile (12) is embedded between the returns (8) and (9) of the plate (6) avoids any risk of sliding of the profile relative to the plate in the event of accidental failure of the welds.

Il est à noter que la structure générale des trois poteaux (3a,3b,3c) est exactement la même, aux différences de dimensions près, le poteau ' (3a) permettant la fixation de trois lisses, celui (3b) de deux lisses, et celui (3c) d'une seule lisse. La structure de ces poteaux est intéressante, en ce sens qu'elle permet, comme montré à a figure 1 d'aligner plusieurs poteaux de hauteurs différentes, pour fixer sur eux une lisse continue.It should be noted that the general structure of the three posts (3a, 3b, 3c) is exactly the same, apart from the dimensional differences, the post '(3a) allowing the attachment of three rails, that (3b) of two rails, and that (3c) of a single stringer. The structure of these posts is interesting, in that it allows, as shown in Figure 1 to align several posts of different heights, to fix on them a continuous rail.

Les trois types de poteaux comportent chacun, dans le retour inférieur (8) formant platine, plusieurs trous (17) (quatre dans l'exemple du dessin) permettant la fixation du poteau au sol. Compte tenu de la présence du décrochement (10) ménagé à l'extrémité inférieure de chaque poteau, les trous (17) situés du côté de l'avant du poteau peuvent être sensiblement déportés vers l'avant par rapport au cas où la partie inférieure du poteau serait droite, ce qui favorise la résistance du poteau à l'arrachement lorsqu'un choc est exercé sur lui du côté de la voie de circulation:The three types of posts each have, in the lower return (8) forming a plate, several holes (17) (four in the example of the drawing) allowing the post to be fixed to the ground. Given the presence of the recess (10) formed at the lower end of each post, the holes (17) located on the side of the front of the post can be offset substantially forward relative to the case where the lower part of the post would be straight, which favors the resistance of the post to tearing off when a shock is exerted on it on the side of the traffic lane:

Selon une autre caractéristique avantageuse de l'invention, cette barrière comporte des moyens simples et esthétiques de fixation des lisses sur les poteaux et de liaison des lisses entre elles.According to another advantageous characteristic of the invention, this barrier comprises simple and aesthetic means of fixing the beams on the posts and connecting the beams together.

A cet effet, chaque lisse (4) comporte dans sa face tournée du côté des poteaux une fente longitudinale (18) débouchant dans une fente longitudinale (19) de section élargie, dans le fond de laquelle est ménagé, en regard de la fente (18), un évidement (20), comme montré à la figure 7. 4 To this end, each stringer (4) has, in its face turned towards the side of the posts, a longitudinal slot (18) opening into a longitudinal slot (19) of enlarged section, in the bottom of which is arranged, facing the slot ( 18), a recess (20), as shown in FIG. 7. 4

La face de la lisse (4) opposée à la face de fixation sur les poteaux comprend pour sa part un évidement longitudinal (21). La liaison entre deux lisses (4) disposées bout à bout est réalisée par manchonnage intérieur. A cet effet, un profilé (22) est engagé dans les deux tronçons de lisse (4) à réunir, où il est bloqué par vissage. Une vis (23) est engagée dans la lisse (4) et dans le profilé de manchonnage (22), du côté extérieur de la lisse, cette vis étant bloquée par un écrou venant se loger dans t'évidement (20) de la lisse. Placé en continu ou ponctuellement au niveau des têtes de vis, un ruban longitudinal (24) à effet décoratif ou de signalisation, fixé par encliquetage par déformation élastique peut être engagé dans le logement longitudinal en forme de gorge (21).The face of the heddle (4) opposite the fixing face on the posts for its part comprises a longitudinal recess (21). The connection between two heddles (4) arranged end to end is carried out by internal sleeving. To this end, a profile (22) is engaged in the two sections of heddle (4) to be joined, where it is blocked by screwing. A screw (23) is engaged in the heald (4) and in the sleeving profile (22), on the outside of the heald, this screw being blocked by a nut which is received in the recess (20) of the heald . Placed continuously or punctually at the level of the screw heads, a longitudinal strip (24) with decorative or signaling effect, fixed by snap-fastening by elastic deformation can be engaged in the longitudinal groove-shaped housing (21).

Comme montré à la figure 8, la fixation d'une lisse au niveau d'un trou (13) ménagé dans un poteau est réalisée par une vis (25) dont la tête (26), logée dans l'évidement (20) de la lisse prend appui sur une plaquette (27) logée dans la fente (19) de la lisse, cette vis étant bloquée sur le poteau par un écrou (28).As shown in Figure 8, the fixing of a rail at a hole (13) formed in a post is made by a screw (25) whose head (26), housed in the recess (20) of the heald is supported on a plate (27) housed in the slot (19) of the heald, this screw being locked on the post by a nut (28).

Cette structure est très intéressante d'une part, au plan pratique . car limitant la complexité des pièces et le nombre de pièces utilisées, et d'autre part au plan esthétique puisque chaque lisse ne comporte du côté des poteaux, qu'une seule fente longitudinale continue alors que les lisses traditionnelles comportent le plus souvent deux ou trois fentes.This structure is very interesting on the one hand, in practical terms. because limiting the complexity of the parts and the number of parts used, and on the other hand from an aesthetic point of view since each stringer only comprises on the side of the posts, a single continuous longitudinal slot whereas the traditional struts most often comprise two or three slots.

Dans la mesure où cela est nécessaire, cette barrière peut être équipée très facilement, comme cela est montré à la figure 2, d'un grillage (29) situé par exemple en avant des lisses (4). Il suffit pour cela de prévoir des pattes (30) et (32) fixées respectivement sur un point de fixation de la lisse haute, et sur un point de fixation de la lisse basse ou du support, ces pattes étant équipées à leurs extrémités libres de dispositifs connus d'accrochage et de mise en tension du grillage.Insofar as this is necessary, this barrier can be very easily fitted, as shown in FIG. 2, with a grid (29) situated for example in front of the heddles (4). For this, it suffices to provide lugs (30) and (32) fixed respectively on a point of attachment of the top arm, and on a point of attachment of the bottom arm or of the support, these lugs being equipped at their free ends with known devices for attaching and tensioning the mesh.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant une barrière possibilités d'adaptations en fonction du site à équiper, possédant d'excellentes qualités de résistance mécanique ainsi qu'une esthétique très agréable.As is apparent from the above, the invention provides a great improvement to the existing technique by providing a barrier possibilities of adaptations depending on the site to be equipped, with excellent mechanical resistance qualities as well as a very pleasant aesthetic.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de cette barrière, ni à ses seules composants décrits ci-dessus à titre d'exemple, elle en embrasse, au contraire, toutes les variantes de réalisation.It goes without saying that the invention is not limited to the sole embodiment of this barrier, nor to its only components described above by way of example, on the contrary, it embraces all variants of it. production.
