Description

L'invention concerne un bloc séparateur de voies en matière plastique destiné tout particulièrement à délimiter des voies de circulation, notamment lors de travaux pouvant être effectués sur la chaussée.The invention relates to a plastic lane separator block intended in particular to delimit traffic lanes, in particular during work that can be carried out on the roadway.

Un tel séparateur devant, pouvoir être réalisé en matière plastique et être de ce fait creux intérieurement au moins partiellement, le déposant a été confronté à des problèmes liés à la tenue en flexion des parois longitudinales extérieures du bloc, notamment en cas de choc où d'efforts ponctuels, que ce soit en cours de fabrication ou en exploitation.Such a separator in front, being able to be made of plastic material and therefore being internally at least partially hollow, the depositor was confronted with problems linked to the flexural strength of the external longitudinal walls of the block, in particular in the event of an impact where '' ad hoc efforts, whether during production or in operation.

L'invention a pour objet de résoudre ces problèmes et propose à cet effet que le bloc séparateur qui est donc creux intérieurement et est pourvu à sa base d'un fond, soit renforcé par au moins un pilier intérieur creux se dressant à l'écart des parois extérieures longitudinales et latérales du bloc, en étant toutefois raccordé localement à ces dites parois longitudinales, en partie supérieure.The invention aims to solve these problems and proposes for this purpose that the separator block which is therefore hollow internally and is provided at its base with a bottom, be reinforced by at least one hollow internal pillar standing apart longitudinal and lateral outer walls of the block, while being locally connected to these said longitudinal walls, in the upper part.

De préférence, ce pilier se terminera, du côté opposé au fond à partir duquel il se dresse, par une paroi transversale "de sommet" raccordée latéralement auxdites parois longitudinales extérieures du bloc, via de courtes cloisons de liaison, isolées de l'extérieur, prolongeant ainsi latéralement la paroi transversale en question.Preferably, this pillar will end, on the side opposite the bottom from which it rises, by a transverse "top" wall connected laterally to said external longitudinal walls of the block, via short connecting partitions, isolated from the outside, thus extending laterally the transverse wall in question.

Ainsi on va pouvoir absorber une partie importante des efforts de flexion pouvant être exercés sur l'extérieur du bloc, évitant dans la pratique que ses parois longitudinales se déforment.Thus we will be able to absorb a large part of the bending forces that can be exerted on the outside of the block, preventing in practice that its longitudinal walls are deformed.

En outre, en écartant de ces parois extérieures du bloc les cloisons constitutives du pilier, pourra-t-on favoriser la fabrication par rotomoulage de la pièce, laissant entre les parois en question un espace suffisant pour l'écoulement de la matière lors de la coulée pendant la fabrication de la pièce.In addition, by removing from these outer walls of the block the partitions constituting the pillar, can we promote the manufacture by rotational molding of the part, leaving between the walls in question sufficient space for the flow of material during the casting during the production of the part.

D'autres caractéristiques et avantages de l'invention apparaîtront encore de la description qui va suivre faite en référence aux dessins annexés donnés uniquement à titre d'exemple et dans lesquels :

  • la figure 1 illustre une vue de face d'un bloc séparateur conforme à l'invention,
  • la figure 2 montre une vue de desous du bloc de la figure 1, dans le sens de la flèche II,
  • la figure 3 est une vue transversale en coupe le long de la ligne III-III de la figure 4,
  • et la figure 4 est une vue comparable à celle de la figure 1 avec arrachement.
Other characteristics and advantages of the invention will appear from the description which follows made with reference to the appended drawings given solely by way of example and in which:
  • FIG. 1 illustrates a front view of a separator block according to the invention,
  • FIG. 2 shows a view from below of the block of FIG. 1, in the direction of arrow II,
  • FIG. 3 is a cross-sectional view along the line III-III of FIG. 4,
  • and Figure 4 is a view comparable to that of Figure 1 with cutaway.

Sur les figures, on voit donc illustrer un bloc ou plot séparateur de voies, en matière plastique susceptible d'être en particulier fabriqué par rotomoulage et destiné à être utilisé par des services de voirie ou notamment par des sociétés de travaux publics.The figures therefore show a block or block separating tracks, made of plastic material which can in particular be manufactured by rotational molding and intended for use by road services or in particular by public works companies.

Le bloc séparateur 1 se présente en l'espèce sous la forme d'un élément de muret d'environ 70 cm de hauteur et 100 à 110 cm de longueur.The separator block 1 is in the present case in the form of a wall element of approximately 70 cm in height and 100 to 110 cm in length.

Vers ses extrémités longitudinales opposées il comporte, dans l'alignement de ses parois, des excroissances formant crénelages 5a, 5b et 7,décalés et complémentaires d'un côté à l'autre du bloc, de manière à permettre la réalisation d'une chaine d'éléments, des barres de liaison (non représentées) prévues pour pénétrer dans les orifices verticaux 9 ou 11 des excroissances, assurant l'assemblage de deux éléments consécutifs (voir figure 4).Towards its opposite longitudinal ends it has, in alignment with its walls, protrusions forming notches 5a, 5b and 7, offset and complementary from one side to the other of the block, so as to allow the production of a chain of elements, connecting bars (not shown) intended to penetrate into the vertical orifices 9 or 11 of the protuberances, ensuring the assembly of two consecutive elements (see FIG. 4).

Pour faciliter la manutention, l'élément 1 peut-être équipé en partie supérieure de passages 12 qui le traversent de part en part pour déboucher sur ses parois longitudinales extérieures 3, 5. Ces passages pourront être dimensionnés pour recevoir les fourches d'un chariot de manutention.To facilitate handling, the element 1 can be equipped in the upper part with passages 12 which pass right through it to lead to its external longitudinal walls 3, 5. These passages can be dimensioned to receive the forks of a carriage Handling.

On notera que de tels passages à parois pleines rigidifient le bloc en ce qu'ils raccordent entre-elles les parois 3 et 5 (voir figure 3).It will be noted that such passages with solid walls stiffen the block in that they connect the walls 3 and 5 to one another (see FIG. 3).

Egalement dans le but de faciliter le déplacement des blocs, un canal demi-cylindrique 14 pourra être formé dans la paroi transversale supérieure 12' de chaque passage, permettant ainsi la mise en place d'une barre ou toute autre tige de levage.Also in order to facilitate movement blocks, a semi-cylindrical channel 14 could be formed in the upper transverse wall 12 'of each passage, thus allowing the installation of a bar or any other lifting rod.

Dans la pratique, le bloc 1 sera préférentiellement réalisé en matière plastique, telle que du polyéthylène moyenne densité.In practice, the block 1 will preferably be made of plastic, such as medium density polyethylene.

Pour favoriser la stabilité de chaque bloc, les parois longitudinales 3, 5 seront avantageusement, et comme illustré plus clairement aux figures 1 et 3, inclinées pour donner au bloc en coupe verticale transversale (figure 3) une forme allant en s'évasant du sommet vers la base à l'endroit de laquelle le bloc est pourvu d'un panneau de fond 13 sensiblement horizontal, tel qu'illustré figure 2.To promote the stability of each block, the longitudinal walls 3, 5 will advantageously, and as illustrated more clearly in Figures 1 and 3, be inclined to give the block in vertical cross section (Figure 3) a shape flaring from the top towards the base where the block is provided with a substantially horizontal bottom panel 13, as illustrated in FIG. 2.

Ainsi, en coupe verticale transversale, le bloc pourra présenter sensiblement la forme d'un tronc de pyramide.Thus, in vertical transverse section, the block may have substantially the shape of a trunk of a pyramid.

Toutefois, et dans la pratique, ces parois longitudinales 3, 5 pourront présenter une double pente avec un évasement plus prononcé en partie inférieure 1a qu'en partie supérieure 1b du bloc, une ligne de jonction sensiblement horizontale 15 figurant extérieurement le raccordement des pentes de chaque côté du bloc, par exemple environ à mi-hauteur.However, and in practice, these longitudinal walls 3, 5 may have a double slope with a more pronounced flare in the lower part 1a than in the upper part 1b of the block, a substantially horizontal junction line 15 externally showing the connection of the slopes of each side of the block, for example about halfway up.

Intéressons-nous maintenant plus précisément aux figures 2 à 4 pour remarquer que dans le fond 13, est ménagée une sorte de puits ou pilier creux 17 central dont le rôle est de renforcer intérieurement le bloc et plus particulièrement de raidir ses parois longitudinales extérieures 3 et 5.Let us now focus more specifically on FIGS. 2 to 4 to note that in the bottom 13, a sort of central hollow well or pillar 17 is arranged, the role of which is to internally reinforce the block and more particularly to stiffen its external longitudinal walls 3 and 5.

A cet effet, le pilier creux qui remonte donc vers l'intérieur du bloc à partir du fond 13 avec lequel il vient de matière, se raccorde localement auxdites parois 3 et 5, de manière que les efforts subis par ces parois puissent être transmis et absorbés par les parois du pilier, lequel comprend en l'espèce quatre parois latérales 19 formant un tronc de pyramide et fermées à leur sommet par une paroi transversale continue 21.To this end, the hollow pillar which therefore rises towards the inside of the block from the bottom 13 with which it comes, is locally connected to said walls 3 and 5, so that the forces undergone by these walls can be transmitted and absorbed by the walls of the pillar, which in this case comprises four side walls 19 forming a trunk of a pyramid and closed at their top by a continuous transverse wall 21.

De cette façon, la rigidité du pilier sera assurée et ses parois latérales pourront s'étendre à l'écart des parois longitudinales en regard du bloc avec lesquelles il y aura raccordement à l'endroit des zones 23 situées au niveau de la paroi transversale de sommet 21, celle-ci formant ainsi voile de retenue en poussée et de liaison transversale "directe" entre les deux parois opposées 3 et 5 du bloc (voir figure 3).In this way, the rigidity of the pillar will be ensured and its side walls may extend away from the longitudinal walls opposite the block with which there will be connection at the location of the zones 23 located at the transverse wall of vertex 21, the latter thus forming a retaining veil in thrust and a "direct" transverse connection between the two opposite walls 3 and 5 of the block (see FIG. 3).

De préférence, pour des questions de facilité de fabrication, les zones 23 de raccordement pourront être constituées non pas par de simples lignes mais par de courtes cloisons légèrement inclinées par rapport à l'horizontale et prolongeant la paroi 21, de manière que les lignes de jonction 25 entre cette paroi de sommet 21 et les parois latérales 19 du pilier soient situées légèrement à l'écart des parois longitudinales extérieures 3 et 5 du bloc.Preferably, for reasons of ease of manufacture, the connection zones 23 may be formed not by simple lines but by short partitions slightly inclined relative to the horizontal and extending the wall 21, so that the lines of junction 25 between this top wall 21 and the side walls 19 of the pillar are located slightly away from the outer longitudinal walls 3 and 5 of the block.

Au-dessus de la paroi 21, les parois latérales opposées du pilier sensiblement parallèles aux parois 3, 5 du bloc se prolongeront alors par les tronçons de parois 27 pratiquement verticaux venant réunir entre-elles les parois en question du bloc et du pilier entre la zone de raccordement de pente 15 et chaque cloison 23.Above the wall 21, the opposite lateral walls of the pillar substantially parallel to the walls 3, 5 of the block will then be extended by the sections of practically vertical walls 27 coming to join together the walls in question of the block and the pillar between the slope connection zone 15 and each partition 23.

Dans la pratique, il sera conseillé de conformer le pilier creux de renforcement 17 de manière que sa paroi de sommet 21 soit située à une hauteur h (par rapport au fond 13) inférieure à la distance d séparant ce même fond de la ligne de raccordement 15, favorisant ainsi une concentration des éléments de renforcement dans la partie inférieure la plus exposée et la plus fragile du bloc, compte-tenu de sa forme allant en s'élargissant vers sa base d'assise au sol, le renforcement de la partie supérieure (au-dessus du niveau de raccordement 15) étant malgré tout favorisé par la présence des passages de renforcement 12.In practice, it will be advisable to conform the hollow reinforcement pillar 17 so that its top wall 21 is located at a height h (relative to the bottom 13) less than the distance d separating this same bottom from the connection line. 15, thus favoring a concentration of the reinforcing elements in the most exposed and most fragile lower part of the block, given its shape which widens towards its seat base on the ground, the reinforcement of the upper part (above the connection level 15) being nevertheless favored by the presence of the reinforcement passages 12.

On notera également qu'avec une telle structure cloisonnée en matière plastique assez rigide, les efforts subis par le bloc pourront être correctement absorbés, chaque paroi transmettant à celle(s) à laquelle(auxquelles) elle est raccordée, une partie au moins des efforts qu'elle subit, cette transmission d'effort s'opérant d'autant mieux que l'ensemble de l'élément est monobloc et formé en une seule pièce avec continuité de matière.It will also be noted that with such a partitioned structure made of fairly rigid plastic, the forces undergone by the block can be correctly absorbed, each wall transmitting to the one (s) to which (which) it is connected, at least part of the stresses it undergoes, this force transmission taking place all the better as the whole of the element is in one piece and formed in one piece with continuity of material.

Accessoirement, il pourrait être envisagé d'accroître encore la stabilité des blocs en les lestant.Incidentally, it could be envisaged to further increase the stability of the blocks by ballasting them.

A cet effet, on pourrait par exemple envisager de les remplir partiellement d'eau.For this purpose, one could for example consider partially filling them with water.

Bien entendu, différentes variantes de réalisation de la présente invention pourraient être envisagées.Of course, various alternative embodiments of the present invention could be envisaged.

A ce titre, il pourrait par exemple être prévu de réaliser des blocs renfermant plusieurs piliers creux de raidissement répartis d'endroits en endroits le long de leurs parois longitudinales et ayant une hauteur appropriée fonction de la position des zones à renforcer. Egalement, il pourrait être prévu de rajouter des cloisonnements au(x) pilier(s), en particulier par adjonction de parois transversales telles que 19, 21 jouant le rôle d'éléments d'arc-boutement.As such, it could for example be provided to make blocks containing several hollow stiffening pillars distributed from place to place along their longitudinal walls and having an appropriate height depending on the position of the areas to be reinforced. Also, provision could be made to add partitions to the pillar (s), in particular by adding transverse walls such as 19, 21 acting as bracing elements.
