Description

La présente invention concerne le domaine de l'industrie des revêtements routiers et analogue, en particulier des pavés en béton et a pour objet un pavé en béton autobloquant.The present invention relates to the field of the road surfacing industry and the like, in particular concrete pavers and relates to a block of self-locking concrete.

Actuellement, il existe différents types de pavés en béton pour la réalisation de surfaces destinées à la circulation de véhicules ou encore de simples surfaces destinées à des passages seulement périodiques de véhicules ou à des fins de stationnement. De tels pavés sont généralement munis de moyens d'emboîtement permettant leur blocage suivant deux directions dans le plan horizontal, ces moyens étant souvent des formes géométriques prévues sur les bords desdits pavés et présentant une symétrie inverse entre les bords parallèles des pavés.Currently, there are different types of concrete pavers for producing surfaces for vehicular traffic or simple surfaces for only periodic vehicle passes or for parking purposes. Such pavers are generally provided with interlocking means allowing their locking in two directions in the horizontal plane, these means being often geometric shapes provided on the edges of said pavers and having an inverse symmetry between the parallel edges of the pavers.

En outre, les pavés connus sont équipés d'éléments distanceurs également prévus sur leurs bords et permettant d'assurer la formation d'un joint de séparation destiné à être comblé par un remplissage de sable.In addition, the known pavers are equipped with spacers elements also provided on their edges and to ensure the formation of a separation seal to be filled by a sand filling.

Les pavés connus permettent de répondre de manière relativement correcte aux exigences de blocage et d'anti-déboîtement hors d'une surface posée dans les cas où des critères de circulation très stricts peuvent être remplis, à savoir des vitesses de déplacement relativement faibles engendrant de très faibles vibrations.The known pavers make it possible to respond relatively correctly to the requirements for blocking and anti-dislodging out of a laid surface in cases where very strict circulation criteria can be fulfilled, namely relatively low speeds of movement generating very weak vibrations.

En effet, les pavés existants actuellement, de type autobloquant ou non présentent des bords parfaitement verticaux, de même que les distanceurs dont ils sont équipés, de sorte que le sable de jointoiement permet uniquement de réaliser, par vibration, un blocage efficace, suivant les deux directions dans le plan horizontal.In fact, the existing pavers, of the self-locking or non-locking type, have perfectly vertical edges, as well as the spacers with which they are equipped, so that the grouting sand only makes it possible to achieve, by vibration, an effective blocking, according to the two directions in the horizontal plane.

On connaît également, par DE-U-202 01 877 un bloc muni de distanceurs ayant une section décroissante de la base vers la face apparente et qui ne présentent pas de contact ponctuel de leur base avec celle des blocs adjacents. En outre, il subsiste un jeu longitudinal et transversal qui ne permet pas d'obtenir un blocage efficace des blocs. De plus, l'épaulement prévu dans ce document ne permet pas une fermeture du joint au niveau du lit de pose, de sorte que le sable de joint peut se déverser dans ce lit de pose lors de vibrations. Enfin, les distanceurs ne sont nullement en contact sur toute leur hauteur.We also know, by DE-U-202 01 877 a block provided with spacers having a decreasing section from the base to the apparent face and which do not have a point contact of their base with that of the adjacent blocks. In addition, there is a longitudinal and transverse clearance that does not allow to obtain an effective block blocking. In addition, the shoulder provided in this document does not allow closure of the seal at the laying bed, so that the seal sand can pour into the laying bed during vibration. Finally, the spacers are not in contact at all their height.

Par ailleurs, EP-A-1 036 882 décrit un pavé de type analogue à celui décrit dans le document précédent et appelle les mêmes remarques. Ce pavé ne permet pas non plus d'obtenir une résistance "anti-arrachage", les distanceurs étant uniquement destinés à assurer le positionnement lors de la pose et se détruisant lors de la vibration de la surface posée.Otherwise, EP-A-1,036,882 describes a type of block similar to that described in the previous document and calls the same remarks. This block also does not allow to obtain a resistance "anti-pulling", the spacers being only intended to ensure positioning during installation and destroying during the vibration of the laid surface.

DE-U-297 21 360 décrit un pavé muni de moyens de blocage, mais sans interpénétration, dans lequel les éléments distanceurs sont uniquement prévus sur une partie de la hauteur à partir de la base, garantissant ainsi un joint apparent uniforme ne laissant pas paraître lesdits distanceurs. DE-U-297 21 360 discloses a block provided with locking means, but without interpenetration, wherein the spacing elements are only provided on a part of the height from the base, thus ensuring a uniform apparent seal does not appear said distancers.

Cependant, dans le cas d'une circulation importante et à vitesse relativement élevée sur de tels pavés, les vibrations induites ont tendance à provoquer successivement des failles de très faible largeur sur les bords parallèles, de sorte qu'à chaque passage lesdits pavés réalisent un micro déplacement correspondant. Il en résulte qu'après une durée plus ou moins longue de service, le sable de jointoiement entre les pavés a tendance à se déplacer partiellement sous ces derniers permettant l'obtention d'un jeu avec les pavés voisins. En outre, ce jeu peut être augmenté du fait d'une érosion vers le haut des pavés due aux sollicitations d'ordres mécanique et météorologique, ce qui a pour conséquence, lors d'un passage de véhicule, un soulèvement desdits pavés par un effet ventouse des pneumatiques desdits véhicules sur la surface extérieure desdits pavés. Il s'ensuit une détérioration rapide de la surface carrée et la formation de bruits parasites dues à l'entrechoquement dû aux vibrations et à l'entrechoquement, voire au déchaussement desdits pavés, ce qui est particulièrement pénible pour les riverains.However, in the case of a large circulation and at a relatively high speed on such paving stones, the induced vibrations tend to successively cause faults of very small width on the parallel edges, so that each passage said blocks realize a corresponding micro displacement. It follows that after a shorter or longer period of service, the grouting sand between the pavers tends to move partially under the latter to obtain a clearance with neighboring blocks. In addition, this game can be increased due to an erosion up the cobblestones due to mechanical and meteorological demands, which has the consequence, during a passage of a vehicle, lifting said pavers by an effect pneumatic suction cup said vehicles on the outer surface of said pavers. It follows a rapid deterioration of the square surface and the formation of spurious noise due to the interception due to vibration and the interception, or even loosening of said pavers, which is particularly painful for residents.

Enfin, on connaît, par WO-A-0009808 un pavé présentant sur deux côtés consécutifs des distanceurs pouvant s'imbriquer mutuellement pour garantir un "anti-arrachage". Toutefois, de tels pavés sont de réalisation par moulage extrêmement difficile et nécessitent une pose spécifique par emboîtement par les côtés, pratiquement irréalisable avec des machines de pose et entraînant un problème de glissement sur le lit de sable, sans entraînement de ce dernier, lors d'une pose manuelle. Enfin, la fabrication et la pose de tels pavés sont d'un prix de revient incompatibles avec une mise en oeuvre industrielle.Finally, we know, by WO-A-0009808 a block having on two consecutive sides spacers that can interlock each other to ensure "anti-pulling". However, such blocks are made by extremely difficult molding and require a specific fitting by interlocking sides, practically unrealizable with laying machines and causing a sliding problem on the sand bed, without driving the latter, when manual installation. Finally, the manufacture and installation of such pavers are cost price incompatible with industrial implementation.

Par ailleurs, il a été proposé, par EP-A-1 705 289 , un pavé en béton autobloquant, pourvu sur ses bords longitudinaux et transversaux de moyens distanceurs en forme de tronc de pyramide ou de tronc de cône, dans lequel lesdits moyens distanceurs sont disposés de part et d'autre d'écarteurs semi cylindriques et rejoignent par paires, par leur base, la génératrice de l'écarteur correspondant la plus éloignée du pavé, chaque moyen distanceur étant, lors de l'interpénétration des pavés en position de pose, en contact par un point avec le bord longitudinal ou transversal du pavé voisin et par un point avec un distanceur correspondant du pavé voisin, les écarteurs étant en contact sur toute leur hauteur avec le bord correspondant du pavé voisin par une ligne.In addition, it was proposed by EP-A-1,705,289 , a block of self-locking concrete, provided on its longitudinal and transverse edges means in the form of a truncated pyramid or truncated cone, wherein said spacing means are arranged on either side of semi-cylindrical spacers and join in pairs, by their base, the generatrix of the corresponding spacer most away from the block, each distance means being, in the interpenetration of the pavers in the laying position, in contact by a point with the longitudinal or transverse edge of the neighboring block and by a point with a corresponding spacing of the neighboring block, the spacers being in contact all their height with the corresponding edge of the neighboring block by a line.

Un tel pavé permet d'obvier largement à la majorité des inconvénients des pavés existant à ce jour, mais ne peut garantir sur une longue durée un verrouillage absolu contre un arrachement, du fait d'une usure possible des distanceurs à leurs points de contact entraînant une migration du sable de jointoiement vers le lit de pose et ainsi un jeu entre pavés voisins.Such a block makes it possible to largely obviate the majority of the disadvantages of the pavers existing to date, but can not guarantee for a long time an absolute locking against tearing, due to possible wear of the spacers at their contact points causing a migration of grouting sand to the laying bed and thus a game between neighboring blocks.

La présente invention a pour but de pallier ces inconvénients en proposant un pavé en béton autobloquant permettant d'assurer simultanément un auto blocage dans les deux directions du plan horizontal de pose, ainsi qu'un verrouillage en position contre un arrachement, par suppression de tout jeu entre pavés, tout en étant d'une mise en oeuvre et de fabrication simples.The present invention aims to overcome these disadvantages by providing a block of self-locking concrete to simultaneously ensure self-locking in both directions of the horizontal laying plane, and locking in position against tearing, by removing all play between pavers, while being a simple implementation and manufacturing.

A cet effet, le pavé en béton autobloquant, pourvu sur ses bords longitudinaux et transversaux de moyens distanceurs, disposés de part et d'autre d'écarteurs, est caractérisé en ce que les moyens distanceurs sont en forme de tronc de pyramide à base polygonale et coopèrent, par forme, avec la base des moyens distanceurs des pavés voisins, lors de l'interpénétration des pavés en position de pose, et en ce que les écarteurs sont disposés dans l'axe vertical médian des moyens distanceurs, présentent une forme de demi tronc de cône ou de demi tronc de pyramide, dont la grande base s'étend au niveau de la base polygonale du moyen distanceur correspondant, partiellement en saillie par rapport à cette dernière, chaque écarteur coopérant avec un évidement vertical correspondant, prévu dans le bord du pavé voisin et dont la section est égale à celle de la grande base de l'écarteur et constante sur toute la hauteur du pavé.For this purpose, the self-blocking concrete paver, provided on its longitudinal and transverse edges with means spacers, arranged on both sides of spacers, is characterized in that the spacer means are in the form of truncated pyramid polygonal base and cooperate, by shape, with the base of the means spacers of the neighboring blocks, during the interpenetration of the pavers in the laying position, and in that the spacers are arranged in the median vertical axis of the spacer means, have a shape of half truncated cone or half truncated pyramid, whose large base extends at the polygonal base of the corresponding distance means, partially projecting relative thereto, each spacer cooperating with a corresponding vertical recess, provided in the edge of the neighboring block and whose section is equal to that of the large base of the spacer and constant over the entire height of the pavement.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en perspective d'un pavé conforme à l'invention ;
  • la figure 2 est une vue en plan, à plus grande échelle, du pavé ;

  • Les figures 1 et 2 des dessins annexés représentent un pavé autobloquant 1 en béton destiné à être posé sur des voies de circulation, des aires de stationnement ou autres. Ce pavé 1 est pourvu sur ses bords longitudinaux 2 et transversaux 3 de moyens distanceurs 4, disposés de part et d'autre d'écarteurs 5.
The invention will be better understood, thanks to the following description, which relates to a preferred embodiment, given as a non-limiting example, and explained with reference to the attached schematic drawings, in which:
  • the figure 1 is a perspective view of a pavement according to the invention;
  • the figure 2 is a plan view, on a larger scale, of the pavement;
  • the figure 3 is a partial view in elevation, on a larger scale, of an average assembly spacer and spacer, and
  • the figure 4 is a plan view of a set of laid pavers.
  • The Figures 1 and 2 attached drawings are a self-blocking paver 1 made of concrete to be placed on traffic lanes, parking areas or other. This block 1 is provided on its longitudinal edges 2 and transverse 3 distance means 4, arranged on both sides of spacers 5.

Conformément à l'invention, les moyens distanceurs 4 sont en forme de tronc de pyramide à base polygonale et coopèrent, par forme, avec la base des moyens distanceurs 4 des pavés 1 voisins, lors de l'interpénétration des pavés en position de pose (figure 4), et les écarteurs 5 sont disposés dans l'axe vertical médian des moyens distanceurs 4, présentent une forme de demi tronc de cône ou de demi tronc de pyramide, dont la grande base s'étend au niveau de la base polygonale du moyen distanceur 4 correspondant (figure 3), partiellement en saillie par rapport à cette dernière, chaque écarteur 5 coopérant avec un évidement vertical 6 correspondant, prévu dans le bord du pavé 1 voisin et dont la section est égale à celle de la grande base de l'écarteur 5 et constante sur toute la hauteur du pavé 1.According to the invention, the distance means 4 are in the form of a truncated pyramid with a polygonal base and cooperate, by shape, with the base of the spacing means 4 of the adjacent blocks 1, during the interpenetration of the blocks in the laying position ( figure 4 ), and the spacers 5 are arranged in the central vertical axis of the means 4 spacers, have a form of half truncated cone or half truncated pyramid, the large base extends at the polygonal base of the means distancer 4 corresponding ( figure 3 ), partially projecting from the latter, each spacer 5 cooperating with a corresponding vertical recess 6, provided in the edge of the adjacent block 1 and whose section is equal to that of the large base of the spacer 5 and constant on the entire height of pavement 1.

Les moyens distanceurs 4 et les écarteurs 5 sont disposés sur lesdits bords longitudinaux 2 et transversaux 3 suivant une symétrie inverse, respectivement par rapport à l'axe médian transversal et à l'axe médian longitudinal. Ainsi, il est possible d'obtenir un appareillage de pavés 1 par lequel les bords transversaux et les bords longitudinaux de pavés 1 adjacents par leurs bords longitudinaux et par leurs bords transversaux sont parfaitement alignés (figure 4). En outre, cette disposition permet également une pose en quinconce, avec décalage longitudinal des pavés 1, ainsi qu'une pose à angle droit, un pavé 1 étant disposé perpendiculairement à un autre pavé 1, avec alignement du bord longitudinal de l'un avec le bord transversal de l'autre (figure 4).The distance means 4 and the spacers 5 are arranged on said longitudinal and transverse edges 2 3 in inverse symmetry, respectively with respect to the transverse central axis and the longitudinal median axis. Thus, it is possible to obtain a paver apparatus 1 by which the transverse edges and the longitudinal edges of pavers 1 adjacent by their longitudinal edges and by their transverse edges are perfectly aligned ( figure 4 ). In addition, this arrangement also allows a staggered laying, with longitudinal offset of the blocks 1, and a laying at right angles, a block 1 being arranged perpendicularly to another block 1, with alignment of the longitudinal edge of the one with the transverse edge of the other ( figure 4 ).

Cette disposition des pavés 1 est assurée par l'interpénétration des bases des moyens distanceurs 4, ainsi que des écarteurs 5 et des évidements verticaux 6, comme représenté sur la figure 4 des dessins annexés. Il résulte de cette interpénétration que chaque moyen distanceur 4 est en contact, par sa base polygonale, avec un côté de la base polygonale de deux moyens distanceurs 4 successifs du bord longitudinal 2 ou transversal 3 d'un pavé 1 voisin, tandis que les écarteurs 5, prévus dans l'axe vertical desdits moyens distanceurs 4, coopèrent par forme avec les évidements correspondants 6 desdits bords longitudinal 2 ou transversal 3.This arrangement of the pavers 1 is ensured by the interpenetration of the bases of the distance means 4, as well as the spacers 5 and the vertical recesses 6, as shown in FIG. figure 4 attached drawings. It results from this interpenetration that each distance means 4 is in contact, by its polygonal base, with one side of the polygonal base of two successive spacing means 4 of the longitudinal edge 2 or transverse 3 of a neighboring block 1, while the spacers 5, provided in the vertical axis of said distance means 4, cooperate formally with the corresponding recesses 6 of said longitudinal or transverse edges 2 3.

Les écarteurs 5, qui sont en forme de demi tronc de cône ou de demi tronc de pyramide, dont la grande base s'étend au niveau de la base polygonale du moyen distanceur 4 correspondant, sont en contact, par leur base, avec la partie inférieure des évidements verticaux 6 correspondants des bords des pavés 1 voisins.The spacers 5, which are in the form of a half-truncated cone or half-truncated pyramid, whose large base extends at the level of the polygonal base of the means 4 corresponding distance, are in contact, by their base, with the part lower corresponding vertical recesses 6 edges of the neighboring 1 blocks.

Conformément à une caractéristique de l'invention, chaque bord longitudinal 2 et transversal 3 du pavé 1 est avantageusement pourvu à une extrémité d'un écarteur 5 se prolongeant, en direction du bord correspondant, par un moyen distanceur 4 de section incomplète, à savoir préférentiellement d'un demi distanceur, alors qu'à leur extrémité opposée, lesdits bords 2 et 3 sont pourvus d'un évidement vertical 6, lesdits écarteurs et demi distanceurs étant disposés sur les bords opposés suivant une symétrie inverse. Une telle réalisation permet d'effectuer un assemblage de pavés à mi-longueur ou à mi-largeur, tout en assurant un blocage parfait suivant les deux directions dans le plan horizontal et en délimitant un interstice vertical 7 au niveau de chaque coin des pavés 1, lors de la pose. En effet, la conformation des extrémités des bords longitudinaux et transversaux entraîne une interruption du contact entre les bases des pavés voisins au niveau de leurs coins, mais sans pour autant empêcher un blocage parfait contre tout déplacement dans un plan horizontal, l'interstice vertical 7 étant rempli de sable de jointoiement garantissant le blocage des pavés 1.According to a feature of the invention, each longitudinal edge 2 and transverse 3 of the block 1 is advantageously provided at one end of a spacer 5 extending, towards the corresponding edge, by a spacer means 4 of incomplete section, namely preferably at a half distance, while at their opposite end, said edges 2 and 3 are provided with a vertical recess 6, said spacers and half distancers being arranged on the opposite edges in a reverse symmetry. Such an embodiment makes it possible to perform an assembly of blocks at mid-length or at mid-width, while ensuring a perfect locking in both directions in the horizontal plane and delimiting a vertical gap 7 at each corner of the paving stones 1 , during the pose. Indeed, the conformation of the ends of the longitudinal and transverse edges causes an interruption of the contact between the bases of neighboring blocks at their corners, but without preventing a perfect blockage against any displacement in a horizontal plane, the vertical gap 7 being filled with grouting sand ensuring blocking of pavers 1.

Du fait de la conformation des moyens distanceurs 4 et des écarteurs 5 les pavés 1 posés sont entièrement en contact mutuel par leur base reposant sur le lit de pose, les interstices verticaux 7, remplis de sable de jointoiement permettant de parfaire la tenue des pavés contre tout risque de rippage, qui pourrait entraîner une déstabilisation de l'ensemble de pavés posés.Due to the conformation of the spacers means 4 and the spacers 5 the pavers 1 laid are fully in mutual contact by their base resting on the laying bed, the vertical interstices 7, filled with grouting sand to perfect the holding of pavers against any risk of ripping, which could lead to destabilization of the set of pavers laid.

Selon une autre caractéristique de l'invention, les écarteurs 5 déterminent, avec les évidements verticaux 6 correspondants, des espaces de jointoiement par du sable, à section progressive à partir de la face inférieure des pavés 1 vers leur face supérieure, réalisant une auto compression sous un effort d'arrachement ou d'affaissement. Ainsi, le remplissage de sable de jointoiement réalise non seulement une stabilisation des pavés dans le plan horizontal, mais forme également un moyen d'auto blocage en coopération avec les distanceurs 4 et écarteurs 5. De plus, à proximité des coins, le remplissage des interstices verticaux 7 assure une répartition du sable en direction des ensembles distanceurs 4 et écarteurs 5 voisins et garantit leur remplissage et donc la qualité du jointoiement.According to another characteristic of the invention, the spacers 5 determine, with the corresponding vertical recesses 6, grouting spaces by sand, progressive section from the lower face of the blocks 1 to their upper face, achieving a self-compression under a pulling or sagging effort. Thus, the filling of grouting sand not only achieves a stabilization of the blocks in the horizontal plane, but also forms a self-locking means in cooperation with the spacers 4 and spacers 5. In addition, near the corners, the filling of vertical gaps 7 provides a distribution of sand towards the distance 4 and spacer 5 neighbors and guarantees their filling and thus the quality of grouting.

La formation de ce moyen d'auto blocage résulte du fait qu'une tentative d'arrachement d'un pavé a pour effet d'induire un déplacement du sable de jointoiement au niveau des ensembles écarteurs 5 et évidements verticaux 6, qui a pour effet une compression simultanée du sable de jointoiement, cette compression s'effectuant, en fait, en cascade et aboutissant à un blocage total empêchant tout arrachement ou affaissement.The formation of this self-locking means results from the fact that an attempt to tear off a block has the effect of inducing a displacement of the grouting sand at the level of the spacer assemblies 5 and vertical recesses 6, which has the effect of a simultaneous compression of the grouting sand, this compression being effected, in fact, in cascade and resulting in a total block preventing any tearing or sagging.

En outre, du fait du contact des bases des pavés 1 sur pratiquement toute leur longueur et toute leur largeur et de la pénétration des écarteurs 5 dans les évidements 6, un basculement initial des pavés, qui serait du à un jeu initial au niveau desdites bases est rendu impossible, de sorte qu'un arrachement ou un descellement d'un pavé, par un effet de serrage complémentaire sur un côté lors d'une tentative d'arrachage ou suite à un effet de succion provoqué par une bande de roulement déplacée à vitesse élevée sur une surface ainsi pavée, est totalement évité. En effet, non seulement les pavés 1 ne peuvent pas se déplacer dans un plan horizontal, du fait des distanceurs 4 s'interpénétrant et, en outre, des écarteurs 5 coopérant avec les évidements 6, qui empêchent un pivotement des pavés 1 l'un par rapport à l'autre et, de la sorte, tout arrachement ou affaissement, notamment de manière mécanique.In addition, because of the contact of the bases of the blocks 1 over virtually their entire length and width and the penetration of the spacers 5 in the recesses 6, an initial tilting of the blocks, which would be due to an initial game at said bases is made impossible, such as tearing or loosening of a pavement, by a complementary tightening effect on one side during a tearing attempt or following a suction effect caused by a tread displaced to high speed on a paved surface, is totally avoided. Indeed, not only the pavers 1 can not move in a horizontal plane, because of the spacers 4 interpenetrating and, in addition, spacers 5 cooperating with the recesses 6, which prevent pivoting of the pavers 1 one relative to the other and, in this way, any tearing or sagging, especially mechanically.

Grâce à l'invention, il est possible de réaliser un pavé en béton autobloquant permettant d'assurer un auto blocage en position, tant dans le plan de la surface de pose que perpendiculairement à ce plan, c'est-à-dire évitant tout arrachage dans des conditions de circulation, tout en permettant le drainage des eaux de ruissellement à l'assise.Thanks to the invention, it is possible to make a self-locking concrete block to ensure a self-locking position, both in the plane of the laying surface and perpendicular to this plane, that is to say avoiding all pulling in traffic conditions, while allowing the drainage of runoff water to the seat.

En outre, ce pavé peut être réalisé par mise en oeuvre des techniques de moulage habituelles, c'est-à-dire avec utilisation d'un moule simple, monobloc, et la pose est également réalisable de manière simple et rapide.In addition, this block can be made by implementing the usual molding techniques, that is to say using a mold simple, monobloc, and the pose is also achievable in a simple and fast way.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'inventionOf course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
