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. 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 passes of vehicles. 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 faible engendrant de très faibles vibrations.The known pavers make it possible to respond relatively correctly to the requirements of blocking and anti-dislodging out of a laid surface in cases where very strict traffic 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, qui ne présentent, cependant, pas de contact ponctuel de leur base. 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, which do not have, however, no point contact of their base. 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". Enfin, on connaît, par DE-U-297 21 360 un pavé muni de moyens de blocage mais sans interpénétration.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 pavement does not allow to obtain a resistance "anti-pulling". Finally, we know, by DE-U-297 21 360 a block provided with locking means but without interpenetration.

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.

La présente invention a pour but de pallier ces inconvénients en proposant un pavé en béton autobloquant permettant d'assurer simultanément un autoblocage dans les deux directions du plan horizontal de pose, ainsi qu'un verrouillage en position contre un arrachement.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 a locking position against tearing.

A cet effet, le 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, est caractérisé en ce que 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.For this purpose, the self-locking concrete paver, provided on its longitudinal and transverse edges with means of spacers in the form of truncated pyramids or truncated cones, is characterized in that said distance means are arranged on either side of semi-cylindrical spacers and join in pairs, by their base, the generatrix of the spacer corresponding furthest from the block, each distance means being, during the interpenetration of the pavers in the laying position, in contact with a point with the longitudinal or transverse edge of the neighboring block and a point with a corresponding spacing of the neighboring block, the spacers being in contact over their entire height with the corresponding edge of the neighboring block by a line.

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 4 est une vue partielle schématique en plan représentant l'interaction entre les distanceurs, et
  • la figure 5 est une vue partielle en perspective représentant le volume de sable de jointoiement entre deux distanceurs.
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:
  • Figure 1 is a perspective view of a block according to the invention;
  • Figure 2 is a plan view of the block;
  • Figure 3 is a front elevational view of the block;
  • FIG. 4 is a schematic partial plan view showing the interaction between the spacers, and
  • Figure 5 is a partial perspective view showing the volume of grouting sand between two spacers.

Les figures 1 à 3 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 en forme de tronc de pyramide ou de tronc de cône.Figures 1 to 3 of the accompanying drawings show a self-blocking paver 1 concrete to be placed on traffic lanes, parking areas or other. This block 1 is provided on its longitudinal edges 2 and 3 transverse means of spacers 4 shaped truncated pyramid or truncated cone.

Conformément à l'invention, ce pavé est caractérisé en ce que lesdits moyens distanceurs 4, en forme de tronc de pyramide ou de tronc de cône, sont disposés de part et d'autre d'écarteurs semi-cylindriques 5 et rejoignent par paires, par leur base, la génératrice de l'écarteur correspondant 5 la plus éloignée du pavé, chaque moyen distanceur 4 étant, lors de l'interpénétration des pavés en position de pose, en contact par un point 4' avec le bord longitudinal ou transversal du pavé voisin 1 et par un point 4" avec un distanceur 4 correspondant du pavé voisin, les écarteurs 5 étant en contact sur toute leur hauteur avec le bord correspondant du pavé voisin 1 par une ligne 5'.According to the invention, this block is characterized in that said spacer means 4, in the form of a truncated pyramid or truncated cone, are arranged on either side of semi-cylindrical spacers 5 and join in pairs, by their base, the generatrix of the spacer corresponding farthest from the pavement, each distance means 4 being, during the interpenetration of the pavers in the laying position, in contact with a point 4 'with the longitudinal or transverse edge of the neighboring block 1 and a point 4 "with a corresponding spacer 4 of the neighboring block, the spacers 5 being in contact over their entire height with the corresponding edge of the neighboring block 1 by a line 5 '.

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 par lequel les bords transversaux et les bords longitudinaux de pavés adjacents par leurs bords longitudinaux et par leurs bords transversaux sont parfaitement alignés. Cette disposition des pavés est assurée par l'interpénétration des bases des moyens distanceurs 4, comme représenté sur la figure 4 des dessins annexés. Il résulte de cette interpénétration que chaque moyen distanceur 4 est en contact par un point 4' avec le bord longitudinal 2 ou transversal 3 du pavé 1 voisin et par deux points opposés 4" latérales avec des points correspondants 4" des deux distanceurs 4 voisins, les écarteurs 5 étant en contact sur toute leur hauteur avec le bord correspondant du pavé voisin 1 par une ligne 5'. Ainsi, il subsiste à la base des pavés 1 posés des espaces favorisant le drainage tandis que le blocage des pavés 1 entre eux, contre tout déplacement latéral ou transversal, est totalement assuré. Ce drainage permet, par rapport aux pavés connus à ce jour, d'éviter un colmatage étanche des joints par les salissures déposées en surface et se mélangeant au sable de jointoiement, le joint étant, avec les pavés connus, d'une largeur plus faible.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 by which the transverse edges and the longitudinal edges of adjacent pavers by their longitudinal edges and by their transverse edges are perfectly aligned. This layout of the blocks is ensured by the interpenetration of the bases of the distance means 4, as shown in Figure 4 of the accompanying drawings. It results from this interpenetration that each distance means 4 is in contact by a point 4 'with the longitudinal edge 2 or transverse 3 of the neighboring block 1 and by two opposite points 4 "lateral with corresponding points 4" of the two spacers 4 neighbors, the spacers 5 being in contact over their entire height with the corresponding edge of the neighboring block 1 by a line 5 '. Thus, there remains at the base of the pavers 1 posed spaces promoting drainage while the blocking of the pavers 1 between them, against any lateral or transverse movement, is fully assured. This drainage makes it possible, with respect to the pavers known to date, to prevent sealing of the joints by the dirt deposited on the surface and mixing with the grouting sand, the joint being, with the known paving stones, of a smaller width .

Conformément à une caractéristique de l'invention, chaque bord longitudinal et transversal du pavé 1 est avantageusement pourvu à une extrémité d'un distanceur 4 de section incomplète et d'un écarteur 5, à savoir préférentiellement d'un demi-distanceur et d'un écarteur, lesdits demi-distanceurs et écarteurs étant disposés sur les bords opposés suivant une symétrie inverse. Une telle réalisation permet d'effectuer un assemblage de pavé à mi-longueur ou à mi-largeur, tout en assurant un blocage parfait suivant les deux directions dans le plan horizontal.According to a feature of the invention, each longitudinal and transverse edge of the block 1 is advantageously provided at one end of a spacer 4 of incomplete section and a spacer 5, preferably a half-distancer and a spacer, said half-spacers and spacers being disposed on the opposite edges in inverse symmetry. Such an embodiment makes it possible to perform a paving assembly at mid-length or at mid-width, while ensuring perfect locking in both directions in the horizontal plane.

Selon une autre caractéristique de l'invention, les bords de deux pavés voisins déterminent avec leurs distanceurs 4 et écarteurs 5 un espace de jointoiement à surface tronconique ou en forme de tronc de pyramide inversé réalisant une autocompression sous un effort d'arrachement. Ainsi, le remplissage de sable de jointoiement, qui a pour but initial de réaliser une stabilisation des pavés dans le plan horizontal, a, en outre, pour effet de former un moyen d'autoblocage en coopération avec les distanceurs 4 et écarteurs 5.According to another characteristic of the invention, the edges of two adjacent blocks determine with their spacers 4 and spacers 5 a frustoconical surface area or truncated truncated pyramid achieving self-compression under a tearing force. Thus, the filling of grouting sand, whose initial purpose is to stabilize the pavers in the horizontal plane, also has the effect of forming a means of self-locking in cooperation with the spacers 4 and spacers 5.

La formation de ce moyen d'autoblocage résulte du fait qu'une tentative d'arrachement d'un pavé a pour effet d'induire un déplacement du tronc de cône ou de pyramide formé entre deux ensembles distanceurs 4 et écarteur 5 voisins en direction de l'ensemble correspondant du pavé restant en place. Or, du fait de l'existence de distanceurs en forme de troncs de cône ou de pyramide identiques sur chaque côté d'un écarteur 5, le déplacement relatif tendrait à provoquer un déplacement identique. Un tel déplacement n'est, cependant, pas possible du fait qu'il induit simultanément une compression du sable de jointoiement, cette compression s'effectuant, en fait, en cascade et aboutissant à un blocage total empêchant tout arrachement.The formation of this means of self-locking results from the fact that an attempt to tear off a block has the effect of inducing a displacement of the truncated cone or pyramid formed between two sets of spacers 4 and spacer 5 neighbors in the direction of the corresponding set of pavement remaining in place. However, because of the existence of identical shaped cone or pyramid spacers on each side of a spacer 5, the relative displacement would tend to cause an identical displacement. Such displacement is, however, not possible because it simultaneously induces a compression of the grouting sand, this compression being effected, in fact, in cascade and resulting in a total blocking preventing tearing.

La figure 5 des dessins annexés représente schématiquement la forme du remplissage de sable de jointoiement entre deux pavés successifs. Il ressort particulièrement de cette représentation que la partie de jointoiement présente une section croissante entre le fond du joint et le sommet, à savoir la surface supérieure du pavé, de sorte que le sable de jointoiement forme une série de coins entre les bords des pavés, ces coins rendant impossible un descellement ou arrachement 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.Figure 5 of the accompanying drawings schematically shows the shape of the sand filling grouting between two successive blocks. It is particularly apparent from this representation that the grouting portion has an increasing section between the bottom of the joint and the top, namely the upper surface of the pavement, so that the grouting sand forms a series of corners between the edges of the pavers, these corners making it impossible to loosen or tear off a block by a complementary clamping effect on one side during a tearing attempt or following a suction effect caused by a tread moved at a high speed on a surface and paved.

Le sable de jointoiement est un sable concassé de granulométrie usuelle et est destiné à assurer un remplissage parfait des joints entre les bords des pavés adjacents et à se comprimer entre lesdits bords, en service.The grouting sand is a crushed sand of conventional particle size and is intended to ensure perfect filling of the joints between the edges of the adjacent blocks and to compress between said edges, in use.

Grâce à l'invention, il est possible de réaliser un pavé en béton autobloquant permettant d'assurer un autoblocage 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. En outre, ce pavé permet le drainage des eaux de ruissellement à l'assise.Thanks to the invention, it is possible to produce a block of self-locking concrete to ensure self-locking position, both in the plane of the laying surface perpendicular to this plane, that is to say, avoiding any tearing in traffic conditions. In addition, this pavement allows the drainage of runoff water to the seat.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible.
