Abstract

The spacer (300) has an open profile whose cross-section consists of a base (310). A U-shaped branch (320) is perpendicular to the base. Another U-shaped branch (330) is spaced away from the base, and forms a non-right angle with respect to the base. A fixation unit is placed on the base to fix a rail (380). A mounting unit is placed at an end of the branch (320). A supporting unit i.e. base plate (340), is provided at an end of the branch (330) for permitting the end of the branch (330) to build a support against a bracket (370) and to slide against the bracket during shock on the rail.

Description

L'invention concerne un écarteur pour glissière de sécurité muni de moyens de montage pour le monter sur un support et de moyens de fixation pour le fixer à une lisse, et constitué d'une platine métallique formant un profilé. L'invention concerne également des moyens de montage d'un tel écarteur.The invention relates to a retractor for a guardrail provided with mounting means for mounting it on a support and fastening means for fixing it to a rail, and consisting of a metal plate forming a profile. The invention also relates to means for mounting such a spacer.

Les glissières de sécurité sont constituées d'une série de lisses aboutées les unes aux autres et fixées à distances plus ou moins régulières à des supports destinés à les maintenir à la hauteur souhaitée le long de la route. Ces supports peuvent être des poteaux enfoncés dans le sol ou bien des parapets ou des parois en béton.The guardrails consist of a series of hinges abutted to each other and fixed at more or less regular distances to the supports intended to maintain them at the desired height along the road. These supports may be posts sunk in the ground or parapets or concrete walls.

Il est courant d'intercaler des écarteurs entre les lisses et les supports pour les maintenir à distance. Ces écarteurs sont couramment constitués d'un profilé de section carrée ou rectangulaire. Ces écarteurs peuvent également servir à absorber une partie du choc.It is common to insert spacers between the rails and the supports to keep them at a distance. These spacers are usually made of a section of square or rectangular section. These spacers can also be used to absorb some of the shock.

Les écarteurs ont cependant tendance lorsqu'ils se déforment à déverser vers le haut, c'est-à-dire à se déformer en entraînant la lisse vers le haut. C'est d'ailleurs l'effet recherché avec l'écarteur du document EP 0 810 325 A2 . Cet écarteur a une forme en V dont les extrémités sont rabattues d'un même côté perpendiculairement à l'axe médian passant par la pointe du V de sorte que ces deux rabats se situent dans un même plan. À l'état monté, les deux rabats, dirigés vers le bas, sont fixés au poteau. Une lisse, dont la face dirigée vers le poteau est en W, est fixée sur l'écarteur dont la pointe du V épouse la forme du creux central du W. Comme l'indique le document, la forme de l'écarteur est choisie pour qu'en cas de choc, l'écarteur se déforme en assurant un soulèvement de la lisse.The spacers, however, tend when they deform to dump upward, that is to say, to deform by driving the rail up. This is the desired effect with the document retractor EP 0 810 325 A2 . This spacer has a V shape whose ends are folded on the same side perpendicular to the central axis passing through the tip of the V so that these two flaps are located in the same plane. In the assembled state, the two flaps, directed downwards, are fixed to the post. A smooth, whose face facing the post is W, is fixed on the spacer whose tip of the V follows the shape of the central hollow of the W. As indicated in the document, the shape of the spacer is selected for that in case of shock, the spacer is deformed by ensuring an uprising of the arm.

Cependant, dans un tel cas, la lisse n'étant plus à la bonne hauteur, il est possible alors qu'un véhicule léger passe sous la lisse et ne soit plus alors guidé convenablement par celle-ci après le choc.However, in such a case, the arm is no longer at the right height, it is possible while a light vehicle passes under the rail and is then no longer properly guided by it after the shock.

L'objectif de l'invention est donc de proposer un écarteur qui soit conçu pour qu'en cas de choc, il se déforme en provoquant un déversement vers le bas de la lisse.The object of the invention is therefore to provide a spacer which is designed so that in case of shock, it deforms causing a spill down the smooth.

Cet objectif est atteint conformément à l'invention du fait que le profilé est un profilé ouvert dont la section transversale à la forme essentiellement d'un U constitué d'une base sensiblement plane qui se poursuit du côté dit supérieur par une première branche sensiblement perpendiculaire à la base et du côté dit inférieur par une seconde branche s'écartant de la base en formant un angle non droit avec celle-ci, les moyens de fixation étant placés sur la base pour permettre de fixer dessus la lisse, les moyens de montage étant placés à l'extrémité de la première branche du U et des moyens étant prévus à l'extrémité de la seconde branche du U pour permettre à cette extrémité de prendre appui contre le support et de glisser contre celle-ci en cas de choc. En cas de choc, la branche inférieure oblique offre une moindre résistance que la branche supérieure qui est horizontale. Elle va donc se déformer en premier, entraînant la lisse dans un mouvement de déversement vers le bas.This object is achieved according to the invention because the profile is an open section whose cross section substantially in the form of a U consisting of a substantially planar base which continues on the said upper side by a first substantially perpendicular branch at the base and the so-called lower side by a second branch away from the base forming a non-right angle with it, the fastening means being placed on the base to allow the smooth to be fixed on it, the mounting means being placed at the end of the first leg of the U and means being provided at the end of the second leg of the U to allow this end to bear against the support and slide against it in case of impact. In case of shock, the oblique lower branch offers less resistance than the upper branch which is horizontal. It will therefore deform first, causing the smooth in a downward spill motion.

Conformément à l'invention, des moyens sont prévus à l'extrémité de la seconde branche du U pour permettre à cette extrémité de prendre appui contre le support et de glisser contre celui-ci en cas de choc. Ces moyens d'appui sont constitués de préférence par une plaque d'appui prolongeant la seconde branche du U et disposée perpendiculairement à la première branche en s'en éloignant, la longueur de la seconde branche étant choisie de telle sorte que lorsque l'écarteur est monté sur le support, la plaque d'appui vient en contact contre le support.According to the invention, means are provided at the end of the second leg of the U to allow this end to bear against the support and slide against it in case of shock. These support means are preferably constituted by a support plate extending the second branch of the U and disposed perpendicular to the first branch away from it, the length of the second branch being chosen so that when the retractor is mounted on the support, the support plate comes into contact against the support.

Pour forcer l'extrémité de la seconde branche à glisser verticalement contre le support en cas de choc, il est prévu de munir les moyens d'appui de moyens pour guider l'extrémité de la seconde branche du U le long du support.To force the end of the second branch to slide vertically against the support in the event of impact, it is intended to provide the support means with means for guiding the end of the second leg of the U along the support.

Dans un premier mode de réalisation, les moyens de guidage sont constitués d'un trou oblong dans lequel peut pénétrer et coulisser un pion, le pion étant situé sur la plaque d'appui et le trou oblong sur le côté du support faisant face à la lisse, ou inversement.In a first embodiment, the guiding means consist of an oblong hole in which a pin can penetrate and slide, the pin being located on the support plate and the oblong hole on the side of the support facing the smooth, or vice versa.

Dans un deuxième mode de réalisation, les moyens de guidage sont constitués de deux ailes de guidage parallèles disposées à l'extrémité de la seconde branche du U ou sur la plaque d'appui, perpendiculairement au plan défini par la première branche du U de telle sorte que lorsque l'écarteur est monté sur le support, les ailes de guidage viennent en contact, ou pratiquement en contact, contre des surfaces du support perpendiculaires à la lisse.In a second embodiment, the guide means consist of two parallel guide wings arranged at the end of the second leg of the U or on the support plate, perpendicular to the plane defined by the first leg of the U of such so that when the spacer is mounted on the support, the guide wings come into contact, or substantially in contact, against surfaces of the support perpendicular to the smooth.

Il est préférable de munir la première branche d'un renfort, de préférence une cornière en U dont les extrémités des branches sont fixées sur la face supérieure de la première branche de l'écarteur, par exemple par soudure.It is preferable to provide the first branch with a reinforcement, preferably a U-shaped bracket whose ends of the branches are fixed on the upper face of the first branch of the spacer, for example by welding.

Les moyens de montage sont de préférence constitués de deux ailes de montage placées sur une plaque support, de préférence constituée par la première branche du profilé en U de l'écarteur, les deux ailes de montage étant parallèles entre elles et séparées l'une de l'autre de telle sorte que la distance séparant les faces extérieures opposées des ailes de montage corresponde sensiblement à la distance séparant deux faces intérieures d'un support parallèles à la lisse. Pour éviter une déformation des ailes de montage, il est préférable de placer un renfort entre les deux ailes de montage.The mounting means are preferably constituted by two mounting flanges placed on a support plate, preferably constituted by the first branch of the U-shaped section of the spacer, the two mounting flanges being parallel to one another and separated from one another. the other such that the distance separating the opposite outer faces of the mounting flanges corresponds substantially to the distance separating two inner faces of a support parallel to the rail. To avoid deformation of the mounting flanges, it is best to place a reinforcement between the two mounting flanges.

Lorsque le support est muni d'une âme centrale perpendiculaire à la lisse, il est préférable que les moyens de montage comprennent un deuxième jeu d'ailes de montage de préférence munies d'un second renfort.When the support is provided with a central core perpendicular to the rail, it is preferable that the mounting means comprise a second set of mounting flanges preferably provided with a second reinforcement.

Afin de permettre la fixation de l'écarteur sur le support, il peut être avantageux de munir le ou les renforts d'un trou ou d'une fente oblongue dans lequel peut passer par exemple un boulon. Ce boulon pourra être dimensionné de telle sorte qu'il serve de fusible placé entre l'extrémité de la première branche du U et le support.In order to make it possible to fix the spacer to the support, it may be advantageous to provide the reinforcement (s) with an oblong hole or slot into which a bolt may pass, for example. This bolt may be sized so that it serves as a fuse placed between the end of the first leg of the U and the support.

Un écarteur (100, 200, 300, 400, 500) conforme à l'invention est constitué essentiellement d'une plaque métallique formant un profilé en U. La base du U (110, 210, 310, 510) se poursuit du côté dit supérieur par une première branche (120, 220, 320, 520) et du côté dit inférieur par une seconde branche (130, 230, 330, 530). Les références « côté supérieur » et « côté inférieur » se rapportent à la position de ces branches lorsque l'écarteur est monté sur le support.A spacer (100, 200, 300, 400, 500) according to the invention consists essentially of a metal plate forming a U-shaped profile. The base of the U (110, 210, 310, 510) continues on the said side. upper by a first leg (120, 220, 320, 520) and said lower side by a second leg (130, 230, 330, 530). The references "upper side" and "lower side" refer to the position of these branches when the spacer is mounted on the support.

La base du U (110, 210, 310, 510) est sensiblement plane. Comme le montre la figure 4, il est prévu d'y fixer la lisse (380) par tout moyen approprié. En ce qui concerne la lisse, il peut s'agir d'une lisse métallique ou d'une lisse en bois, comme dans la figure 4. Dans cette figure, la lisse (380) est fixée par un étrier en U (390). Cependant, tout autre moyen de fixation peut être envisagé. Dans l'exemple présenté, la base du U (110, 210, 310, 510) est munie d'un trou (111, 211, 311, 511) pour laisser passer la tige de l'étrier en U (390), ce trou formant une partie des moyens de fixation de la lisse.The base of the U (110, 210, 310, 510) is substantially planar. As shown in figure 4 it is intended to fix the arm (380) by any appropriate means. Regarding the smooth, it can be a metal smooth or a smooth wooden, as in the figure 4 . In this figure, the beam (380) is fixed by a U-shaped stirrup (390). However, any other means of attachment can be envisaged. In the example shown, the base of the U (110, 210, 310, 510) is provided with a hole (111, 211, 311, 511) for passing the stem of the U-shaped stirrup (390). hole forming part of the attachment means of the smooth.

La première branche (120, 220, 320, 520) est sensiblement perpendiculaire à la base (110, 210, 310, 510). Elle porte à son extrémité opposée à la base (110, 210, 310, 510) des moyens (121, 221, 321, 521) pour le montage de l'écarteur (100, 200, 300, 400, 500) sur le support (370, 470).The first leg (120, 220, 320, 520) is substantially perpendicular to the base (110, 210, 310, 510). It carries at its end opposite the base (110, 210, 310, 510) means (121, 221, 321, 521) for mounting the spacer (100, 200, 300, 400, 500) on the support (370, 470).

La seconde branche du U (130, 230, 330, 530) est inclinée par rapport à la première branche (120, 220, 320, 520) de sorte qu'elle n'est pas perpendiculaire à la base (110, 210, 310, 510). Il est préférable que cette deuxième branche (130, 230, 330, 530) s'écarte de la première (120, 220, 320, 520) en s'éloignant de la base (110, 210, 310, 510).The second leg of the U (130, 230, 330, 530) is inclined relative to the first leg (120, 220, 320, 520) so that it is not perpendicular to the base (110, 210, 310). , 510). It is preferable that this second leg (130, 230, 330, 530) deviates from the first leg (120, 220, 320, 520) away from the base (110, 210, 310, 510).

Ainsi, lorsque l'écarteur (100, 200, 300, 400, 500) est monté sur le support (370, 470), l'extrémité de la première branche (120, 220, 320, 520) est montée sur le support (370, 470) à l'aide des moyens de montage (121, 221, 321, 521) de telle sorte que cette première branche (120, 220, 320, 520) soit dans le plan horizontal et la base (110, 210, 310, 510) dans le plan vertical parallèle à la lisse (380) et donc à la route. La deuxième branche (130, 230, 330, 530) fait par conséquent un angle non droit par rapport au support (370, 470). La longueur de la deuxième branche (130, 230, 330, 530) par rapport à celle de la première (120, 220, 320, 520) est choisie de telle sorte que l'extrémité opposée à la base (110, 210, 310, 510) de la deuxième branche (130, 230, 330, 530) soit en contact avec le support (370, 470) et puisse glisser contre ce dernier en cas de choc.Thus, when the spacer (100, 200, 300, 400, 500) is mounted on the support (370, 470), the end of the first branch (120, 220, 320, 520) is mounted on the support ( 370, 470) by means of the mounting means (121, 221, 321, 521) so that said first leg (120, 220, 320, 520) is in the horizontal plane and the base (110, 210, 310, 510) in the vertical plane parallel to the rail (380) and therefore to the road. The second branch (130, 230, 330, 530) is therefore a non-right angle relative to the support (370, 470). The length of the second leg (130, 230, 330, 530) relative to that of the first (120, 220, 320, 520) is chosen such that the end opposite the base (110, 210, 310, 510) of the second leg (130, 230, 330, 530) is in contact with the support (370, 470) and can slide against the latter in the event of impact.

Il est préférable que la seconde branche du U (130, 230, 330, 530) se prolonge, à son extrémité opposée à la base (110, 210, 310, 510), par une plaque d'appui (140, 240, 340, 440, 540). La plaque d'appui (140, 240, 340, 440, 540) est sensiblement parallèle à la base du U (110, 210, 310, 410, 510). Lorsque l'écarteur (100, 200, 300, 400, 500) est monté sur le support (370, 470), cette plaque prend donc appui contre ce dernier.It is preferable that the second leg of the U (130, 230, 330, 530) is extended at its end opposite the base (110, 210, 310, 510) by a support plate (140, 240, 340). , 440, 540). The backing plate (140, 240, 340, 440, 540) is substantially parallel to the base of the U (110, 210, 310, 410, 510). When the spacer (100, 200, 300, 400, 500) is mounted on the support (370, 470), this plate bears against it.

Conformément à l'invention, cette plaque d'appui (140, 240, 340, 440, 540) ou, lorsque l'écarteur n'en est pas muni, l'extrémité de la seconde branche (130, 230, 330, 530) opposée à la base (110, 210, 310, 510) n'est pas fixe par rapport au support, mais au contraire peut glisser sur celui-ci.According to the invention, this support plate (140, 240, 340, 440, 540) or, when the spacer is not provided, the end of the second branch (130, 230, 330, 530 ) opposite to the base (110, 210, 310, 510) is not fixed relative to the support, but on the contrary can slide on it.

Lorsqu'un choc se produit, la force qui en découle est en général dans le plan horizontal plus ou moins incliné par rapport à la lisse. En cas de choc sur la lisse, la force est transmise d'une part à la branche horizontale qui la transmet au support sur lequel elle est montée et d'autre part à la branche inclinée qui s'appuie contre le support tout en pouvant glisser contre lui. Dans ces conditions, la force du choc va provoquer la déformation de l'écarteur. La plaque d'appui va glisser vers le bas contre le support, la base va suivre le mouvement en se translatant vers le support et vers le bas tandis que l'extrémité de la première branche (120, 220, 320, 520) portant les moyens de montage formera le point dur. En utilisant pour fixer la première branche (120, 220, 320, 520) sur le support une vis fusible, celle-ci cédera sous l'effet de l'effort et l'extrémité portant les moyens de montage sera éjectée du support. La lisse se retrouvera à une hauteur inférieure à sa hauteur initiale.When an impact occurs, the resulting force is generally in the horizontal plane more or less inclined relative to the smooth. In the event of impact on the rail, the force is transmitted on the one hand to the horizontal branch which transmits it to the support on which it is mounted and on the other hand to the inclined branch which bears against the support while being able to slide against him. Under these conditions, the force of the shock will cause the deformation of the spacer. The support plate will slide down against the support, the base will follow the movement by moving towards the support and down while the end of the first branch (120, 220, 320, 520) carrying the mounting means will form the hard point. Using to fix the first branch (120, 220, 320, 520) on the support a fuse screw, it will yield under the effect of the force and the end bearing the mounting means will be ejected from the support. The smooth will be found at a height lower than its initial height.

Pour augmenter la résistance de la première branche (520), il est possible de la munir d'un renfort. Dans l'exemple présenté à la figure 7, ce renfort est constitué par une cornière (529) en U retournée dont les extrémités des branches sont soudées à la face supérieure de la première branche. Il serait bien sûr possible de prévoir d'autre forme de renfort, tel que par exemple un renfort en T ou en double T. Ce renfort s'étend de préférence sur toute la longueur de la première branche. Il va de soi que ce renfort n'est pas limité à cette variante du deuxième mode de réalisation et peut être prévu sur tous les autres modes de réalisation de l'invention.To increase the resistance of the first branch (520), it is possible to provide a reinforcement. In the example presented at figure 7 , this reinforcement is constituted by a U-shaped bracket (529) whose ends of the branches are welded to the upper face of the first branch. It would of course be possible to provide another form of reinforcement, such as for example a T or double T reinforcement. This reinforcement preferably extends over the entire length of the first branch. It goes without saying that this reinforcement is not limited to this variant of the second embodiment and can be provided on all the other embodiments of the invention.

Pour permettre le guidage de l'extrémité de la seconde branche (130, 230, 330, 530) ou de la plaque d'appui (140, 240, 340, 440, 540) sur le support (370, 470) lors du choc, il est préférable de prévoir des moyens de guidage.For guiding the end of the second limb (130, 230, 330, 530) or the backing plate (140, 240, 340, 440, 540) to the support (370, 470) upon impact it is preferable to provide guide means.

Dans le premier exemple de réalisation présenté aux figures 1 et 2, ces moyens de guidage sont constitués d'une part d'un pion et d'autre part d'une fente oblongue dans laquelle le pion pénètre et peut coulisser. Dans les figures 1a-c, le pion est constitué par un boulon qui passe dans un trou (141) pratiqué dans la plaque d'appui (140) et dans une fente oblongue réalisée dans le support (370). Il va de soi qu'il est également possible de placer le pion sur le support (370) et la fente oblongue sur la plaque d'appui (140).In the first example of realization presented to Figures 1 and 2 these guide means consist on the one hand of a pin and on the other hand an oblong slot in which the pin penetrates and can slide. In the Figures 1a-c , the pin is constituted by a bolt which passes through a hole (141) formed in the support plate (140) and in an oblong slot made in the support (370). It goes without saying that it is also possible to place the pin on the support (370) and the oblong slot on the support plate (140).

Dans la variante des figures 2a-c, le pion (241) est fixé sur la plaque d'appui (140) et coulisse dans une fente oblongue réalisée dans le support (370).In the variant of Figures 2a-c , the pin (241) is fixed on the support plate (140) and slides in an oblong slot made in the support (370).

Dans le deuxième mode de réalisation représenté aux figures 3 et 7, ces moyens de guidage sont constitués par deux ailes de guidage (342, 542) qui viennent se placer de part et d'autre du support (370). Ces deux ailes de guidage (342, 542) prolongent les bords latéraux verticaux de la plaque d'appui (340, 540) perpendiculairement à cette dernière et parallèlement à l'axe longitudinal du support (370) en formant la base d'un L, la plaque d'appui (340, 540) formant l'autre branche du L. En coupe transversale, la plaque d'appui (340) et les ailes de guidage (342) ont un profil en U dont l'ouverture est dirigée à l'opposée de la lisse. C'est la solution retenue également aux figures 4 et 5 lorsque l'écarteur est placé sur un poteau de type C 100 (370). Si le support est un poteau de type IPE 100 (470), ces ailes de guidage (442) peuvent se prolonger par des rabats (443) perpendiculaires aux ailes de guidage (442) pour enserrer l'une des bases du profilé en double T. Dans ce cas, la plaque d'appui (440), les ailes de guidage (442) et les rabats (443) ont, en coupe transversale, un profil en C dont l'ouverture est dirigée à l'opposé de la lisse.In the second embodiment shown in figures 3 and 7 these guide means are constituted by two guide wings (342, 542) which are placed on either side of the support (370). These two guide wings (342, 542) extend the vertical lateral edges of the support plate (340, 540) perpendicular to the latter and parallel to the longitudinal axis of the support (370) forming the base of an the support plate (340, 540) forming the other leg of L. In cross section, the support plate (340) and the guide wings (342) have a U-shaped profile whose opening is directed at the opposite of the smooth. This is also the solution chosen Figures 4 and 5 when the spacer is placed on a pole of type C 100 (370). If the support is a pole type IPE 100 (470), these guide wings (442) can be extended by flaps (443) perpendicular to the guide flanges (442) for gripping one of the bases of the profile in double T In this case, the support plate (440), the guide flanges (442) and the flaps (443) have, in cross-section, a C-profile whose opening is directed away from the rail. .

Il va de soi que chacun des modes de réalisation des moyens de guidage (pion, ailes de guidage ou ailes de guidage avec rabats) peut être utilisé avec n'importe quel type de poteau (C100, IPE 100, etc).It goes without saying that each of the embodiments of the guiding means (pin, guide flanges or wings with flaps) can be used with any type of post (C100, IPE 100, etc.).

En règle générale, les écarteurs sont montés sur des poteaux constitués par des profilés métalliques. Selon les pays, ces profilés ont différentes formes. On connaît notamment le profilé C 100 (370) dont la section transversale est un C. On connaît le profilé IPE 100 (470) dont la section transversale est en double T. On trouve notamment en Allemagne des profilés en Σ. Dans tous les cas, ces poteaux profilés, une fois mis en place, présentent deux faces parallèles à la route (372, 373, 472, 473). Il est donc prévu conformément à l'invention d'emboîter les moyens de montage (121, 221, 321, 521) de l'écarteur (100, 200, 300, 500) à l'intérieur du profilé du support (370, 470) en appui contre la face interne de ces deux faces (372, 373, 472, 473) parallèles à la lisse (380). Pour cela, les moyens de montage sont constitués d'au moins deux ailes de montage (122, 123, 222, 223, 322, 323, 522, 53) placées sur la face inférieure de la première branche (120, 220, 320, 520) de l'écarteur (100, 200, 300, 500) servant de plaque support. Ces ailes de montage sont par exemple soudées à cette plaque support. Les deux ailes de montage (122, 123, 222, 223, 322, 323, 522, 523) sont parallèles entre elles et séparées l'une de l'autre de telle sorte que la distance séparant les faces extérieures opposées des ailes de montage (122, 123, 222, 223, 322, 323, 522, 523) corresponde sensiblement à la distance séparant deux faces intérieures parallèles à la route d'un support (370, 470). Lors du montage, les deux ailes de montage viennent donc coulisser contre les ailes (372, 373, 472, 473) du poteau parallèle à la route.As a rule, the spacers are mounted on poles made of metal profiles. Depending on the country, these profiles have different shapes. We know in particular the profile C 100 (370) whose cross section is a C. The profile IPE 100 (470) is known whose cross section is in double T. Particularly in Germany there are profil profiles. In all cases, these profiled posts, once in place, have two faces parallel to the road (372, 373, 472, 473). It is therefore provided according to the invention to fit the mounting means (121, 221, 321, 521) of the spacer (100, 200, 300, 500) inside the profile of the support (370, 470 ) against the inner face of these two faces (372, 373, 472, 473) parallel to the smooth (380). For this, the mounting means consist of at least two mounting flanges (122, 123, 222, 223, 322, 323, 522, 53) placed on the underside of the first leg (120, 220, 320, 520) of the spacer (100, 200, 300, 500) serving as a support plate. These mounting flanges are for example welded to this support plate. The two mounting flanges (122, 123, 222, 223, 322, 323, 522, 523) are parallel to each other and separate from one another so that the distance separating the opposite outer faces of the mounting flanges (122, 123, 222, 223, 322, 323, 522, 523) corresponds substantially to the distance separating two inner faces parallel to the road of a support (370, 470). During assembly, the two mounting wings therefore slide against the wings (372, 373, 472, 473) of the pole parallel to the road.

Pour assurer une bonne rigidité aux moyens de montage, il est préférable de relier les deux ailes de montage (122, 123, 222, 223, 322, 323, 522, 523) par un renfort (126, 226, 326, 526) ayant la forme d'une plaque d'entretoise.To ensure good rigidity to the mounting means, it is preferable to connect the two mounting wings (122, 123, 222, 223, 322, 323, 522, 523) by a reinforcement (126, 226, 326, 526) having the shape of a spacer plate.

Lorsque le poteau est muni d'une âme centrale (471), comme c'est le cas du poteau IPE 100 en double T de la figure 6, il peut être utile de placer un double jeu d'ailes de montage (122, 123 / 124, 125) de part et d'autre de l'âme (471) du double T. Ainsi, les ailes de montage (122, 124) situées du côté de l'écarteur (100) sont placées de part et d'autre de l'âme (471) du poteau, en appui contre la branche (472) du poteau située du côté de la route et de la lisse, tandis que les ailes de montage (123, 125) situées à l'opposé de l'écarteur (100) sont placées de part et d'autre de l'âme (471) du poteau, en appui contre la branche (473) du poteau située à l'opposée de la route. Chaque jeu d'ailes de montage (122, 123 / 124, 125) est renforcé par un renfort (126, 127). Ces renforts (126, 127), sont de préférence situés sur les bords latéraux des ailes de montage (122, 123 / 124, 125) situés du côté de l'espace laissé pour l'âme (471) du poteau. Un jeu formé par deux ailes de montage et un renfort (122, 123, 126 / 123, 125, 127) peut être obtenu en soudant trois plaques l'une à l'autre ou par formage d'une platine.When the post is provided with a central core (471), as is the case of the IPE 100 pole double T of the figure 6 it may be useful to place a double set of mounting flanges (122, 123/124, 125) on either side of the core (471) of the double T. Thus, the mounting flanges (122, 124) located on the side of the spacer (100) are placed on either side of the web (471) of the post, resting against the branch (472) of the post located on the side of the road and the rail , while the mounting flanges (123, 125) located opposite the spacer (100) are placed on either side of the web (471) of the column, resting against the branch (473) from the post on the opposite side of the road. Each set of mounting flanges (122, 123/124, 125) is reinforced by a reinforcement (126, 127). These reinforcements (126, 127) are preferably located on the lateral edges of the mounting flanges (122, 123/144, 125) located on the side of the space left for the core (471) of the post. A set formed by two mounting flanges and a reinforcement (122, 123, 126/123, 125, 127) can be obtained by welding three plates to one another or by forming a platen.

Le ou les renforts (126, 127, 226, 326, 526) peuvent être munis d'un trou ou d'une fente oblongue (128, 228, 328, 528) pour permettre le boulonnage des moyens de montage (121, 221, 321, 521) sur le poteau, notamment sur une face du poteau perpendiculaire à la route ou sur l'âme (471) du poteau. Dans l'exemple des figures 4 et 5, le poteau de type C 100 (370) est muni d'un trou (375) dans la section du C qui est perpendiculaire à la route. Ce peut être le fond du C si celui-ci est placé avec son ouverture perpendiculairement à la route (figure 5) ou être une des branches supérieure ou inférieure du C s'il est placé avec son ouverture parallèle à la route.The one or more reinforcements (126, 127, 226, 326, 526) may be provided with an oblong hole or slot (128, 228, 328, 528) to allow bolting of the mounting means (121, 221, 321, 521) on the post, in particular on one side of the post perpendicular to the road or on the web (471) of the post. In the example of Figures 4 and 5 , the C-type post (370) is provided with a hole (375) in the section of the C which is perpendicular to the road. It can be the bottom of the C if it is placed with its opening perpendicular to the road ( figure 5 ) or be one of the upper or lower branches of the C if it is placed with its opening parallel to the road.

Il est avantageux de dimensionner ce boulon de telle sorte qu'il serve de fusible en cas d'accident, permettant aux moyens de montage (121, 221, 321, 521) de sortir du poteau (370, 470) lors de l'écrasement de l'écarteur (100, 200, 300, 500) sous l'effet d'un choc.It is advantageous to dimension this bolt so that it serves as a fuse in the event of an accident, allowing the mounting means (121, 221, 321, 521) to exit the post (370, 470) during the crash. of the spacer (100, 200, 300, 500) under the effect of a shock.

Lorsque le poteau est en C ou en Σ, les moyens de montage ne comprennent qu'un jeu d'ailes de montage (222, 223, 322, 323, 523) éventuellement soutenu par un renfort (226, 326, 526). C'est le cas montré aux figures 2, 3, 4 et 5.When the post is C or Σ, the mounting means comprise only one set of mounting flanges (222, 223, 322, 323, 523) possibly supported by a reinforcement (226, 326, 526). This is the case shown figures 2 , 3 , 4 and 5 .

Il va de soi que les moyens de montage évoqués ici peuvent être utilisés avec tout type d'écarteur. Il suffit de munir ces derniers d'une plaque support qui, lorsque l'écarteur est monté, se trouve perpendiculaire à l'axe longitudinal du poteau.It goes without saying that the mounting means mentioned here can be used with any type of spacer. It is sufficient to provide the latter with a support plate which, when the spacer is mounted, is perpendicular to the longitudinal axis of the pole.

L'écarteur de l'invention est facile à monter et garantit qu'en cas de choc, la lisse se déplace vers le bas. On évite ainsi un déversement vers le haut particulièrement dangereux pour les véhicules légers. Cet écarteur est facile à réaliser dans une platine d'acier.The spacer of the invention is easy to assemble and ensures that in case of shock, the arm moves down. This avoids a spill up particularly dangerous for light vehicles. This spacer is easy to make in a steel plate.

Les moyens de montage conformes à l'invention permettent une mise en place très simple des écarteurs qui sont fixés qu'une fois mis en place. De plus, le boulonnage se fait de préférence depuis le côté du poteau perpendiculaire à la route, donc dans un endroit facile d'accès. En intégrant les moyens de montage à l'intérieur des contours du poteau, il est toujours possible d'habiller ce dernier, notamment par un habillage en bois.

In addition, the bolting is preferably from the side of the post perpendicular to the road, so in a place easily accessible. By integrating the mounting means inside the contours of the post, it is always possible to dress the latter, including a wooden cladding.
