Description

La présente invention a pour objet des éléments de barrières permettant la réalisation de barrières provisoires qui servent notamment à séparer une voie de circulation d'une autre voie de circulation ou d'un chantier ou d'un terrain.The present invention relates to barrier elements allowing the creation of temporary barriers which are used in particular to separate a taxiway from another taxiway or construction site or land.

Le domaine technique de l'invention est celui de la fabrication d'éléments (ou tronçons ou modules) séparateurs, particulièrement d'éléments séparateurs essentiellement réalisés en tôle d'acier pliée, destinés à l'édification et la pose temporaire de barrières (ou glissières) de sécurité mobiles ou déplaçables sur le sol.The technical field of the invention is that of manufacturing separating elements (or sections or modules), particularly separating elements essentially made of folded sheet steel, intended for the construction and temporary installation of barriers (or barriers) of mobile or movable safety on the ground.

Ces barrières ont pour fonction principale d'empêcher la sortie de route d'un véhicule. Le choc d'un véhicule contre une barrière entraíne des efforts importants, notamment de flexion et de traction, que doivent supporter les tronçons séparateurs et leurs jonctions (ou liaisons).The main function of these barriers is to prevent the exit of route of a vehicle. The impact of a vehicle against a barrier causes significant efforts, in particular bending and traction, which must be support the separating sections and their junctions (or connections).

Le brevet EP 485 746 (S.P.S.) décrit un élément de barrière de protection pour la voirie, dont la mobilité en cas de choc est limitée ; à cet effet, l'élément est muni d'un écarteur transversal en forme de plaque trapézoïdale, qui est muni sur toute sa longueur d'une face inférieure dentée de forme ondulée ou en zigzag, favorisant le frottement sur le sol ; cette structure comporte des inconvénients : la forme ondulée de la partie dentée l'empêche de contribuer à la raideur du corps de l'élément de barrière ; par ailleurs, la liaison entre deux éléments par une broche s'engageant dans des plaques, outre les inconvénients liés à cet organe détachable de liaison, empêche également l'ensemble de la structure du séparateur de contribuer de façon homogène à la résistance au choc d'un véhicule contre une barrière constituée de plusieurs éléments assemblés bout à bout.Patent EP 485,746 (S.P.S.) describes a barrier element road protection, whose mobility in the event of impact is limited; In this effect, the element is provided with a transverse plate-shaped spacer trapezoidal, which is provided along its entire length with a lower face wavy or zigzag toothed, favoring friction on the ground; this structure has drawbacks: the wavy shape of the part toothed prevents it from contributing to the stiffness of the body of the element fence ; moreover, the connection between two elements by a pin engaging in plates, in addition to the drawbacks linked to this organ detachable bonding, also prevents the entire structure of the separator to contribute homogeneously to the impact resistance of a vehicle against a barrier made up of several assembled elements end to end.

Le document EP-A-666376 décrit des éléments séparateurs dont chacune des parties latérales inférieures (ou semelles longitudinales) est inclinée par rapport à l'horizontale.The document EP-A-666376 describes separating elements including each of the lower lateral parts (or longitudinal soles) is inclined to the horizontal.

La présente demande a pour objet de proposer des éléments séparateurs de barrière déplaçables, aptes à être posés ou fixés au sol, dont une partie au moins de la structure est métallique, dont la résistance à la déformation sous l'effet d'un choc d'un véhicule soit améliorée.The purpose of this request is to propose elements movable barrier dividers, able to be placed or fixed to the ground, of which at least part of the structure is metallic, whose resistance to deformation due to the impact of a vehicle is improved.

Un objectif de l'invention est de proposer des séparateurs de coût réduit, qui sont améliorés en permettant d'obtenir une barrière plus résistante aux chocs.An objective of the invention is to propose cost separators which are improved by providing a higher barrier impact resistant.

A cet effet, le séparateur selon l'invention est muni, le long de chacune de ses deux parties latérales inférieures , d'une semelle (de forme allongée) longitudinale intégrée au séparateur, qui est renforcée et de préférence inclinée (par rapport à un plan horizontal) d'un angle A au moins égal à 10 degrés et inférieur à 30 degrés.To this end, the separator according to the invention is provided, along each of its two lower lateral parts, of a sole (of form longitudinal) integrated into the separator, which is reinforced and preferably inclined (relative to a horizontal plane) by an angle A to less than 10 degrees and less than 30 degrees.

A cet effet, la semelle comporte de préférence une bande de tôle ou élément longitudinal de paroi (1c, figure 1), sensiblement plan, dont un premier bord longitudinal (dit externe) 17 (figures 1 à 7) repose sur le sol et dont un deuxième bord longitudinal (dit interne) 16 (figures 4 à 7) s'étend au-dessus du sol, à une cote C qui est liée à la largeur L de cet élément de paroi par la relation C = L x tangente (A) ; ainsi, pour un angle A de 20 degrés et une largeur L de 160 millimètres, la cote C sera voisine de 58 millimètres (figure 1).To this end, the sole preferably comprises a sheet metal strip or longitudinal wall element (1c, FIG. 1), substantially planar, of which a first longitudinal edge (called external) 17 (FIGS. 1 to 7) rests on the ground and a second longitudinal edge (called internal) 16 (FIGS. 4 to 7) extends above the ground, at a level C which is linked to the width L of this wall element by the relation C = L x tangent (A) ; thus, for an angle A of 20 degrees and a width L of 160 millimeters, the dimension C will be close to 58 millimeters (Figure 1).

De préférence, la valeur de l'angle A est choisie dans une plage allant de 13 à 26 degrés, en particulier allant de 15 à 24 degrés, et la valeur de la largeur L est choisie dans une plage allant de 80 à 280 millimètres, en particulier allant de 120 à 220 millimètres.Preferably, the value of the angle A is chosen within a range ranging from 13 to 26 degrees, especially ranging from 15 to 24 degrees, and the value of the width L is chosen in a range from 80 to 280 millimeters, in particular from 120 to 220 millimeters.

Les moyens de renfort de cette semelle comportent de préférence une partie (1m, figure 1) sensiblement plane (ou paroi) apte à être posée à plat sur le sol, qui est rigidement fixée (intégrée ou soudée) aux extrémités inférieures des éléments (1c) de parois latérales du séparateur, c'est-à-dire audit premier bord longitudinal ; cette paroi plane horizontale de renfort est prolongée par une partie (1n, figure 1) plane (ou paroi) sensiblement verticale pour former avec la paroi (1m) horizontale un profil coudé en forme de 〈〈 L 〉〉, c'est-à-dire un genre d'équerre allongée s'étendant sous l'extrémité inférieure (1c) des parois latérales du séparateur ; la fixation des bords longitudinaux de la semelle peut être obtenue par soudure ; l'équerre peut également être obtenue par pliage longitudinal de l'extrémité inférieure (1c) du flan latéral.The reinforcing means of this sole preferably include a substantially flat part (1m, FIG. 1) (or wall) capable of being placed at flat on the ground, which is rigidly fixed (integrated or welded) at the ends lower elements (1c) of side walls of the separator, i.e. to said first longitudinal edge; this horizontal flat reinforcement wall is extended by a substantially flat part (1n, FIG. 1) (or wall) vertical to form with the horizontal wall (1m) a bent profile in form of 〈〈 L 〉〉, i.e. a kind of elongated square extending under the lower end (1c) of the side walls of the separator; fixation longitudinal edges of the sole can be obtained by welding; the square can also be obtained by longitudinal folding of the lower end (1c) of the side blank.

La semelle renforcée inclinée s'étend au moins sur une partie substantielle de la longueur du tronçon (ou élément) de barrière, de préférence au moins sur 90 % de la longueur (18, figure 2) du tronçon, en particulier sur toute la longueur du tronçon.The reinforced inclined sole extends at least over part the length of the barrier section (or element), preferably at least over 90% of the length (18, FIG. 2) of the section, in particular over the entire length of the section.

La présence des parois planes (horizontale (1m) et verticale (1n)) de renfort de la semelle permet d'augmenter la résistance du séparateur, en particulier celle des bords inférieurs des parois latérales du séparateur, en particulier dans le cas préféré où la semelle (ou structure inférieure latérale) forme un profil triangulaire (1c, 1m, 1n) fermé.The presence of the flat walls (horizontal (1m) and vertical (1n)) of reinforcement of the sole increases the resistance of the separator, particularly that of the lower edges of the side walls of the separator, in particularly in the preferred case where the sole (or lower structure lateral) forms a triangular profile (1c, 1m, 1n) closed.

La structure du corps du séparateur est d'autant plus renforcée que ses deux parties latérales inférieures (semelles) sont reliées par l'intermédiaire d'une (ou plusieurs) pièce(s) rigide(s) de liaison transversale qui sont notamment solidarisées (de préférence soudées) à chacune des semelles Gauche (G) et Droite (D) dans une zone interne de la semelle et de préférence sensiblement le long dudit bord interne (repéré 16) dudit élément longitudinal (1c) de paroi de la semelle.The structure of the separator body is reinforced all the more its two lower lateral parts (soles) are connected by through one (or more) rigid connecting piece (s) which are in particular joined (preferably welded) to each of the Left (G) and Right (D) soles in an internal zone of the sole and preferably substantially along said internal edge (marked 16) of said longitudinal element (1c) of the sole wall.

Ce bord inférieur renforcé incliné permet, lorsqu'un véhicule appuie dessus par ses roues, non seulement de résister à la déformation résultant de ce poids, mais en outre de transmettre le poids du véhicule au séparateur pour diminuer la capacité de glissement sur le sol du séparateur, et par conséquent diminuer la déformation de la barrière dont il fait partie ; ce bord latéral renforcé permet également lorsqu'un véhicule appuie dessus par ses roues, d'utiliser la totalité du poids du véhicule transmis par les roues et d'empêcher le renversement latéral du séparateur sous le choc.This inclined reinforced lower edge allows, when a vehicle presses above by its wheels, not only to resist the resulting deformation of this weight, but also to transmit the weight of the vehicle to separator to reduce the sliding capacity on the floor of the separator, and therefore reduce the deformation of the barrier of which it is a part ; this reinforced side edge also allows when a vehicle presses above by its wheels, to use the entire weight of the vehicle transmitted by the wheels and prevent the lateral overturning of the separator under impact.

La présence du renfort permet d'éviter d'endommager la semelle lors de manipulations du séparateur ; les séparateurs pouvant être posés par barres de 12 mètres, la première semelle touchant le sol serait rapidement endommagée après quelques manipulations si elle n'était pas renforcée ; ce bord inférieur renforcé permet en outre le ripage (déplacement) facilité du séparateur par soulèvement inférieur avec un nombre réduit de galets passant sous le séparateur : la semelle (1m particulièrement) forme une surface d'appui et de roulement sensiblement plane et résistante.The presence of the reinforcement prevents damage to the sole when handling the separator; separators can be installed in 12-meter bars, the first sole touching the ground would be quickly damaged after a few manipulations if it was not reinforced; this reinforced lower edge also allows the shifting (displacement) ease of the separator by lower lifting with a reduced number of rollers passing under the separator: the sole (1m particularly) forms a substantially bearing and rolling surface flat and resistant.

Les éléments (1m) formant partie de la semelle, et le cas échéant les pièces (1w, figure 1) de liaison transversales, peuvent être munis sur leur face inférieure d'organes rugueux tels que des pointes ou déformations saillantes (métal déployé) ou un patin de caoutchouc pour augmenter leur 〈〈 accrochage 〉〉 par frottement sur le sol.The elements (1m) forming part of the sole, and if necessary the cross linking pieces (1w, figure 1), can be fitted on their underside of rough organs such as spikes or deformities protruding (expanded metal) or a rubber pad to increase their 〈〈 hanging 〉〉 by friction on the ground.

Le fait que les extrémités inférieures des parois latérales du séparateur sont reliées entre elles par des moyens (1w) rigides de liaison transversale, contribue à obtenir un séparateur dont le profil transversal est semi-fermé ou fermé à sa base ; la résistance du séparateur s'apparente alors à celle d'un tube (ou d'une poutre creuse à profil fermé) et sa résistance aux chocs est augmentée ; selon une caractéristique de l'invention, les parois externes principales (1c, 1d, 1e, figure 1) du corps du séparateur sont obtenues par pliage d'un flanc de tôle dans lequel le rayon de courbure du pli est faible, c'est-à-dire généralement inférieur ou égal à 10 millimètres, en particulier de l'ordre de 3 à 7 millimètres ; cette caractéristique est particulièrement avantageuse pour ce qui concerne le pli effectué selon ledit bord (repéré 16) interne (ou deuxième bord longitudinal) dudit élément de paroi de la semelle, qui sépare la semelle de la paroi latérale principale (1d, figure 1) qui est, elle, inclinée par rapport à l'horizontale d'un angle B compris entre 80 degrés et 90 degrés, de préférence de l'ordre de 85 degrés à 90 degrés : ceci favorise en effet une bonne transmission des efforts de la semelle aux moyens rigides de liaison transversale qui reposent au sol, et cela améliore donc la transmission des efforts résultant d'un choc jusqu'au sol ; ce rayon faible permet d'éviter le flambement des parois latérales sous l'effet d'un choc.The fact that the lower ends of the side walls of the separator are connected to each other by rigid connecting means (1w) transverse, contributes to obtain a separator whose transverse profile is semi-closed or closed at the base; the resistance of the separator is similar then that of a tube (or a hollow beam with closed profile) and its impact resistance is increased; according to a characteristic of the invention, the main external walls (1c, 1d, 1e, figure 1) of the body of the separator are obtained by folding a sheet metal side in which the radius of curvature of the fold is small, that is to say generally less or equal to 10 millimeters, in particular of the order of 3 to 7 millimeters; this characteristic is particularly advantageous with regard to the fold performed according to said internal edge (marked 16) (or second edge longitudinal) of said sole wall element, which separates the sole from the main side wall (1d, Figure 1) which is inclined relative to the horizontal of an angle B between 80 degrees and 90 degrees, from preferably of the order of 85 degrees to 90 degrees: this indeed promotes good transmission of forces from the sole to the rigid connecting means which lie on the ground, and this therefore improves the transmission of forces resulting from a shock to the ground; this small radius avoids the buckling of the side walls under the effect of a shock.

En outre, l'utilisation de petits rayons de courbure peut être réalisée avec un outillage peu coûteux.In addition, the use of small radii of curvature can be achieved with inexpensive tools.

Les moyens rigides de liaison transversale peuvent être chacun constitués par une pièce en forme d'un barreau métallique plein de section rectangulaire (figures 4 à 6), ou bien en forme de profilé (creux ou ouvert, figure 7) de section en 〈〈 L 〉〉 en 〈〈 T 〉〉 en 〈〈 U 〉〉 ou en carré;chacun de ces barreaux ou profilés comporte une nervure (ou une arête) orientée suivant l'axe du séparateur, les reliant (par soudure continue ou semi-continue) au bas de la paroi latérale principale du séparateur : ces barreaux ou profilés s'étendent parallèlement entre eux (figures 2, 3) et perpendiculairement à l'axe longitudinal (1b, figures 1, 2) du séparateur, et sont fixés rigidement, en particulier soudés, par chacune de leurs extrémités, à l'une et l'autre des deux semelles (et/ou des renforts de semelle).The rigid transverse connection means can each be consisting of a piece in the shape of a metal bar full of section rectangular (Figures 4 to 6), or in the form of a profile (hollow or open, figure 7) of section in 〈〈 L 〉〉 in 〈〈 T 〉〉 in 〈〈 U 〉〉 or in square; each of these bars or profiles has a rib (or an edge) oriented along the axis of the separator, connecting them (by continuous or semi-continuous welding) to bottom of the main side wall of the separator: these bars or profiles extend parallel to each other (Figures 2, 3) and perpendicular to the longitudinal axis (1b, FIGS. 1, 2) of the separator, and are rigidly fixed, in particular welded, by each of their ends, to one and the other of the two soles (and / or sole reinforcements).

La liaison de la nervure (ou arête) du barreau transversal (1w) avec le bas de la paroi latérale (1d) du séparateur s'effectue de préférence sur une longueur de l'ordre de 10 centimètres (allant de 5 à 20 centimètres), ce qui permet d'avoir une section d'acier de transfert de l'effort entre la paroi latérale du séparateur et les semelles renforcées, qui est de l'ordre de 5 cm2 ; cette liaison est de préférence disposée le long du pli (repéré 16) à rayon de courbure faible séparant la paroi latérale principale (1d) sensiblement verticale de la semelle (1c, 1m, 1n).The connection of the rib (or edge) of the transverse bar (1w) with the bottom of the side wall (1d) of the separator is preferably carried out over a length of the order of 10 centimeters (ranging from 5 to 20 centimeters) , which makes it possible to have a steel section for transferring the force between the side wall of the separator and the reinforced flanges, which is of the order of 5 cm 2 ; this connection is preferably arranged along the fold (marked 16) with a small radius of curvature separating the main lateral wall (1d) substantially vertical from the sole (1c, 1m, 1n).

Selon un mode de réalisation préféré, les parois latérales du séparateur sont reliées entre elles , sur au moins une partie substantielle de leur hauteur, par au moins une structure rigide s'étendant dans un plan transversal sensiblement vertical, par exemple essentiellement constituée par une plaque plane ; chaque séparateur peut comporter plusieurs plaques (repérées 20, figures 2, 3, 14, 15) verticales régulièrement espacées d'une distance voisine de 1 à 3 mètres ; en variante, on peut prévoir des renforts transversaux sous forme de plaques transversales verticales disposées en alternance avec des plaques transversales horizontales (repérées 21 à 23) s'étendant sensiblement à mi-hauteur du corps du séparateur, ces renforts étant espacés de 1 à 2 mètres.According to a preferred embodiment, the side walls of the separator are interconnected, on at least a substantial part of their height, by at least one rigid structure extending in a plane substantially vertical transverse, for example essentially constituted by a flat plate; each separator can have several plates (marked 20, Figures 2, 3, 14, 15) vertical regularly spaced by distance close to 1 to 3 meters; alternatively, reinforcements can be provided transverse in the form of vertical transverse plates arranged in alternating with horizontal transverse plates (marked 21 to 23) extending substantially halfway up the body of the separator, these reinforcements being spaced 1 to 2 meters apart.

Cette structure transversale de renfort permet lors d'un choc de transmettre les efforts d'une première paroi latérale (gauche ou droite) (1d) à une deuxième paroi latérale (respectivement droite ou gauche) et par conséquent à la structure de base comportant les semelles et leurs pièces de liaison transversales, ce qui permet de mieux répartir les efforts dans la structure du séparateur, et par conséquent de mieux transmettre les efforts jusqu'au sol, et de résister à l'écrasement latéral lors du choc. This transverse reinforcement structure allows during a shock of transmit the forces of a first side wall (left or right) (1d) to a second side wall (respectively right or left) and by consistent with the basic structure comprising the soles and their parts transverse connection, which allows better distribution of the forces in the structure of the separator, and therefore to better transmit the forces to the ground, and resist lateral crushing upon impact.

Selon un mode de réalisation, ces renforts transversaux s 'étendent au moins dans la moitié inférieure du séparateur, sont disposés en regard (c'est-à-dire au-dessus) desdits moyens de liaison (1w) rigide qui relient les semelles, et sont rigidement liés (en particulier soudés) à ces liaisons rigides de semelle ; ainsi, les efforts auxquels est soumise une paroi latérale sont transmis efficacement, non seulement à la paroi latérale opposée, mais également au sol, par l'intermédiaire desdits moyens de liaison rigide ainsi que par les semelles coudées équipant les extrémités inférieures latérales du séparateur.According to one embodiment, these transverse reinforcements extend at least in the lower half of the separator, are arranged opposite (that is to say above) of said rigid connection means (1w) which connect the soles, and are rigidly linked (in particular welded) to these connections rigid sole; thus, the forces to which a wall is subjected lateral are transmitted effectively, not only to the lateral wall opposite, but also to the ground, by means of said means of rigid connection as well as by the bent soles equipping the ends lower side of the separator.

Selon un mode particulier de réalisation des structures transversales de renfort, celles-ci s'étendent notamment aux deux extrémités longitudinales du séparateur, et sont rigidement liées aux moyens de liaison de deux tronçons (ou éléments) séparateurs ; par exemple, ces structures transversales (d'extrémité) comportent une platine épaisse d'ancrage de tiges de liaison (mâle) et une platine épaisse associée aux organes femelles de liaison, et/ou comportent des barreaux (repérés 25, figure 15) s'étendant le long de la face interne des parois latérales et supérieures du séparateur.According to a particular embodiment of the transverse structures reinforcement, these extend in particular at the two ends of the separator, and are rigidly linked to the means of connection of two separating sections (or elements); for example, these transverse (end) structures have a thick plate anchor for connecting rods (male) and a thick plate associated with female connecting members, and / or include bars (marked 25, Figure 15) extending along the internal face of the side walls and of the separator.

Les pièces de liaison transversale fixées aux semelles, qui sont affleurantes à la face inférieure des semelles et qui s'appuient donc sur le sol, peuvent être munies d'un ou plusieurs orifice(s) permettant la manutention du séparateur (retourné) par un engin de levage, et/ou permettant le passage au travers de la pièce de liaison d'une broche pour l'ancrage dans le sol d'un séparateur.The transverse connecting pieces attached to the soles, which are flush with the underside of the soles and which therefore rest on the ground, can be provided with one or more orifice (s) allowing the handling of the separator (returned) by a lifting device, and / or allowing the passage through the connecting piece of a pin for anchoring a separator in the ground.

L'amélioration de la rigidité du corps du séparateur permet, à performances égales, d'utiliser une tôle plus fine que celle habituellement prévue, en particulier une tôle dont l'épaisseur est située dans une plage allant de 2 à 4 millimètres, notamment une tôle d'épaisseur voisine de 2,5 à 3,5 millimètres.The improvement in the rigidity of the separator body allows, equal performance, use a thinner sheet than usual provided, in particular a sheet whose thickness is within a range ranging from 2 to 4 millimeters, in particular a sheet of thickness close to 2.5 to 3.5 millimeters.

Par référence à la figure 1 notamment, un corps de séparateur 1 d'axe longitudinal 1b comporte :

  • une paroi supérieure 1e horizontale ;
  • deux patois latérales principales 1d, formant avec la paroi 1e un profil en 〈〈 U 〉〉 évasé vers le bas, symétrique par rapport à un plan longitudinal médian 1a ;
  • deux plis (ou parois) latéraux inférieurs 1c prolongeant la paroi 1d et inclinés par rapport à celle-ci, et qui sont inclinés par rapport au sol d'un angle A ;
  • deux plaques renforts longitudinales horizontales superposées 1s et 1f,
  • deux semelles latérales (gauche et droite) coudées, comportant chacune, outre la paroi 1c, une paroi horizontale 1m et une paroi verticale 1n qui sont fixées rigidement entre elles ainsi qu'aux plis 1c sous lesquels elles s'étendent ;
  • un barreau raidisseur horizontal 1w qui est soudé en 1r aux équerres 1m, 1n, relie les bords renforcés 1m, 1n, 1c et renforce l'ensemble de la structure ; le barreau peut comporter une face inférieure plane munie, sur une partie au moins de sa surface, d'aspérités ;
  • un renfort transversal plan 1t s'étend verticalement ;
  • un petit barreau longitudinal 1u est soudé sur le barreau transversal 1w, et est soudé en 1z à la zone (pli 16, figures 4 à 7) de raccordement des parois 1c et 1d : ce barreau contribue à renforcer la semelle et la structure du séparateur dans son ensemble ;
With reference to FIG. 1 in particular, a separator body 1 with a longitudinal axis 1b comprises:
  • a horizontal upper wall 1e;
  • two main lateral patois 1d, forming with the wall 1e a profile in 〈〈 U 〉〉 flared downwards, symmetrical with respect to a median longitudinal plane 1a;
  • two lower lateral folds (or walls) 1c extending the wall 1d and inclined relative to the latter, and which are inclined relative to the ground by an angle A;
  • two horizontal longitudinal reinforcing plates 1s and 1f,
  • two side soles (left and right) bent, each comprising, in addition to the wall 1c, a horizontal wall 1m and a vertical wall 1n which are rigidly fixed together and to the folds 1c under which they extend;
  • a horizontal stiffening bar 1w which is welded in 1r to the brackets 1m, 1n, connects the reinforced edges 1m, 1n, 1c and reinforces the whole of the structure; the bar may have a flat lower face provided, on at least part of its surface, with roughness;
  • a plane transverse reinforcement 1t extends vertically;
  • a small longitudinal bar 1u is welded to the transverse bar 1w, and is welded in 1z to the zone (fold 16, figures 4 to 7) connecting the walls 1c and 1d: this bar contributes to strengthening the sole and the structure of the separator in general ;

Les éléments de paroi 1c, 1d, 1e sont de préférence obtenus par pliage d'une tôle d'acier de 3 ou 4 millimètres d'épaisseur, selon des rayons de pliage 16, 30 de valeur voisine de 5 millimètres.The wall elements 1c, 1d, 1e are preferably obtained by folding of a sheet of steel 3 or 4 millimeters thick, according to folding radii 16, 30 of a value close to 5 millimeters.

Par référence aux figures 1 à 3 en particulier, le séparateur 1 comporte un corps en tôle de 3 millimètres (2,5 à 4 millimètres) continu sur son pourtour (pour augmenter sa résistance à la torsion), fermé sur toute sa hauteur comportant un corps sensiblement vertical à emprise au sol 10 réduite (inférieure ou égale à 600 millimètres), d'une largeur 11 de tête égale à 20 à 25 % de sa hauteur 12 ; les parois 1d forment un angle (90-B) de 5 degrés avec la verticale et les débords (semelles) 1c latéraux sont pliés avec un rayon de 5 millimètres faisant un angle A de 19,5 degrés avec l'horizontale. Les débords latéraux (semelles) présentent à leur extrémité latérale une forme en tube triangulaire creux de plusieurs centimètres d'épaisseur et sont raidis et reliés par un barreau 1w massif reliant les débords situés sur chaque face.With reference to Figures 1 to 3 in particular, the separator 1 has a continuous 3 mm (2.5 to 4 mm) sheet metal body on its periphery (to increase its resistance to torsion), closed on its entire height comprising a substantially vertical body with a grip at ground 10 reduced (less than or equal to 600 millimeters), with a width 11 of head equal to 20 to 25% of its height 12; the walls 1d form an angle (90-B) 5 degrees with vertical and 1c side overhangs (soles) are folded with a radius of 5 millimeters making an angle A of 19.5 degrees with the horizontal. The lateral overhangs (soles) have at their lateral end a hollow triangular tube shape of several centimeters thick and are stiffened and connected by a massive 1w bar connecting the overhangs located on each side.

La structure du corps du séparateur est d'autant plus renforcée que, d'une part la paroi 1d voisine de la verticale est raidie par la paroi 1c sensiblement perpendiculaire, voisine de l'horizontale, que d'autre part la paroi 1c voisine de l'horizontale est elle-même raidie par le renfort 1n, 1m en tube creux de bord, et qu'enfin les parois inférieures sont encastrées l'une à l'autre par l'intermédiaire d'une pièce 1w de liaison transversale massive.The structure of the separator body is all the more reinforced since, on the one hand the wall 1d close to the vertical is stiffened by the wall 1c substantially perpendicular, close to the horizontal, that on the other hand the wall 1c adjacent to the horizontal is itself stiffened by the reinforcement 1n, 1m in hollow edge tube, and finally the lower walls are embedded to each other via a 1w cross-link piece massive.

Les parois participent donc toutes à la résistance à la flexion, augmentant considérablement l'inertie du séparateur.The walls therefore all participate in the resistance to bending, considerably increasing the inertia of the separator.

Si la liaison rigide est constituée de barreaux 1w pleins (figure 4) comportant une section d'acier de 5 cm2 en contact avec le bas des parois 1d du séparateur, ils sont soudés directement sans ajout de nervure ; dans le cas contraire, une nervure (14, figures 5, 6) orientée suivant l'axe du séparateur est prévue ; dans le cas d'utilisation de tubes creux (figure 7), des goussets (14, figures 5, 6) assurant une liaison de 5 cm2 de section sont prévus entre le bas des parois (1d) du séparateur et le tube creux 1w.If the rigid connection consists of solid bars 1w (FIG. 4) comprising a steel section of 5 cm 2 in contact with the bottom of the walls 1d of the separator, they are welded directly without adding a rib; otherwise, a rib (14, Figures 5, 6) oriented along the axis of the separator is provided; in the case of using hollow tubes (Figure 7), gussets (14, Figures 5, 6) providing a connection of 5 cm 2 in section are provided between the bottom of the walls (1d) of the separator and the hollow tube 1w .

Les semelles renforcées inclinées et leurs moyens de liaison transversale, du fait de la rigidité de la liaison entre l'angle des tôles et le bord renforcé, confèrent au séparateur une grande inertie. Cette disposition permet à la partie du séparateur en contact avec le véhicule, du fait de sa grande inertie (et avec des liaisons transmettant les moments) de mobiliser une grande longueur de séparateur pour retenir le véhicule. Sans ces dispositifs, les bords seraient plus endommagés et le séparateur pivoterait et/ou glisserait davantage lors du choc, du fait de l'affaissement des bords et des parois latérales.Reinforced inclined soles and their connecting means transverse, due to the rigidity of the connection between the angle of the sheets and the reinforced edge, give the separator great inertia. This arrangement allows the part of the separator in contact with the vehicle, the made of its great inertia (and with connections transmitting the moments) of mobilize a large length of separator to retain the vehicle. Without these devices, the edges would be more damaged and the separator pivot and / or slide further during impact due to sagging edges and side walls.

Des renforts transversaux (20, figures 14, 15 notamment) s'étendent sensiblement sur toute la hauteur des parois latérales principales et sont fixés en partie basse (par une section d'acier de 5 cm2 de manière à pouvoir transmettre un effort de compression de plusieurs tonnes, de préférence 10 tonnes) à des patins (ou barreaux transversaux rigides 1w) reportant sur le sol. Les patins sont de préférence munis sur leur face inférieure d'un produit (ou revêtement 26, figure 6) à coefficient de frottement sur le sol très élevé.Cross reinforcements (20, Figures 14, 15 in particular) extend substantially over the entire height of the main side walls and are fixed in the lower part (by a steel section of 5 cm 2 so as to be able to transmit a compressive force of several tonnes, preferably 10 tonnes) to skids (or rigid transverse bars 1w) carrying on the ground. The pads are preferably provided on their underside with a product (or coating 26, Figure 6) with a very high coefficient of friction on the ground.

Ainsi, les efforts auxquels est soumise une paroi latérale sont transmis efficacement, non seulement à la paroi latérale opposée, mais également au sol, par l'intermédiaire desdits patins.Thus, the forces to which a side wall is subjected are transmitted effectively, not only to the opposite side wall, but also on the ground, by means of said pads.

La structure du séparateur comporte ainsi une chaíne ininterrompue d'éléments fonctionnant en compression entre la face où frappe le véhicule et l'appui au sol. Les éléments (profil transversal, paroi, barreau, patin) sont liaisonnés les uns aux autres pour transmettre la force par 5 cm2 de section d'acier (environ).The structure of the separator thus comprises an uninterrupted chain of elements operating in compression between the face where the vehicle strikes and the ground support. The elements (transverse profile, wall, bar, shoe) are linked to each other to transmit force by 5 cm 2 of steel section (approximately).

Ces patins massifs seront confondus avec les moyens de liaison rigide des semelles coudées par souci d'économie mais la géométrie peut imposer entre le bord inférieur de la paroi quasi verticale du séparateur et le moyen de liaison rigide, un barreau en acier permettant le transit de la compression, par 5 cm2 d'acier (environ).These solid pads will be combined with the rigid connection means of the bent soles for the sake of economy, but the geometry may impose between the lower edge of the almost vertical wall of the separator and the rigid connection means, a steel bar allowing the transit of compression, with 5 cm 2 of steel (approximately).

Les séparateurs illustrés figures 2 et 15 présentent la particularité d'avoir les bords des extrémités longitudinales (de contact avec le séparateur voisin) renforcés par des plats de 10 millimètres d'épaisseur environ, fixés par points de soudure.The separators illustrated in Figures 2 and 15 have the particularity to have the edges of the longitudinal ends (contact with the neighboring separator) reinforced by 10 mm thick plates approximately, fixed by welding points.

Cette disposition permet de mieux résister aux manutentions ; lors du choc d'un véhicule, les désaffleurements entre un séparateur et le suivant sont diminués.This arrangement makes it easier to resist handling; when vehicle impact, mismatches between a separator and the next are decreased.

Le séparateur présente la particularité d'avoir des organes constituant deux anneaux de levage en partie supérieure et inférieure permettant de saisir le séparateur, en position normale et en position retournée, avec des élingues se refermant sur l'anneau ; les organes de manutention disposés en partie inférieure sont obtenus par la présence d'un orifice 50 (figures 3, 6) percé dans le barreau 1w ; les organes disposés en partie supérieure sont obtenus par la présence d'un orifice 51 (figures 2, 13) jouxtant l'orifice 40 - orifices prévus dans la paroi 1e -, et par un barreau 52 renforçant la portion de la paroi 1e s'étendant entre ces orifices ; cette disposition permet une amélioration de la sécurité et une plus grande rapidité de montage et de démontage.The separator has the particularity of having organs constituting two lifting rings in the upper and lower part for gripping the separator, in normal position and in position turned over, with slings closing on the ring; the organs of handling arranged in the lower part are obtained by the presence an orifice 50 (Figures 3, 6) drilled in the bar 1w; organs arranged in the upper part are obtained by the presence of an orifice 51 (Figures 2, 13) adjoining the orifice 40 - orifices provided in the wall 1e -, and by a bar 52 reinforcing the portion of the wall 1e extending between these holes; this arrangement improves safety and faster assembly and disassembly.

Le séparateur présente la particularité d'avoir des trous 40, figure 13, en partie supérieure et médiane permettant de superposer un complément de barrière de sécurité tel qu'un écran opaque 41 (figure 15), qui est muni de deux barres verticales 42 s'engageant dans deux trous 40 superposés, respectivement prévus dans la paroi supérieure 1e et dans la pièce de renfort 23 ; cette disposition permet de mettre et d'enlever une barrière avec des dispositifs de fixation très simples. The separator has the particularity of having holes 40, figure 13, in the upper and middle part making it possible to superimpose a additional security barrier such as an opaque screen 41 (FIG. 15), which is provided with two vertical bars 42 engaging in two holes 40 superimposed, respectively provided in the upper wall 1e and in the reinforcement piece 23; this arrangement makes it possible to put and remove a barrier with very simple fixing devices.

Chaque semelle peut comporter sur sa face inférieure des dents ou picots, ou bien un film ou coussinet caoutchouté.According to another aspect, the invention relates to an improved device of attachment to the separator floor, which is illustrated in FIGS. 8, 9 and 13; the device comprises several pins 60 (or piles) comprising two separable parts: a first part 61 of cylindrical spindle provided with its lower end with a tip 63 and provided at its second end (upper) of a threaded portion 64 allowing the connection by screwing of a second part 62, the cylindrical body of the first part 61 being of diameter between 10 and 100 millimeters, in particular of around 30 to 70 millimeters, which part is intended to be planted at remains in the ground, substantially flush with its upper end ; a second part 62 which has a complementary threaded part of the threaded part 64, which has a head 65, for example hexagonal able to cooperate with a screwing tool such as a wrench, and which includes a transverse orifice 66 horizontal for the passage of a key or screw 67; the separating element comprises a rigid transverse bar 1w provided with a orifice 70 for passage of the spindle, a part 71 pierced with an orifice for spindle passage; the part 71 and / or the bar 1w includes (-nt) a orifice 72 for passage of a key 67 for securing the element separator with pin 60 for anchoring in the ground.
