Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • the existing pavers, self-locking type or not have perfectly vertical edges, as well as the spacers with which they are equipped, so that the grouting sand only allows to achieve, by vibration, an effective blocking, following both directions in the horizontal plane.
  • 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 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.
  • 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.
  • EP-A-2,527,533 a block of self-locking concrete, provided on its longitudinal and transverse edges means distance, arranged on both sides of spacers.
  • This block has polygonal base-shaped pyramidal trunk spacers that cooperate, in shape, with the base of the spacing means of the neighboring blocks, during the interpenetration of the blocks in the laying position, and the spacers are arranged in the median vertical axis of the means spacers, have a form of half-truncated cone or half-truncated pyramid, whose large base extends at the polygonal base of the corresponding spacing 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 block.
  • Such a block of self-locking concrete ensures a self-locking position, both in the plane of the laying surface perpendicular to this plane, that is to say, avoiding tearing in traffic conditions.
  • the subject of the present invention is a self-locking concrete paver which, like the paving stone according to EP-A-2,527,533 on the one hand, to simultaneously ensure self-locking in both directions of the horizontal laying plane, as well as locking in position against tearing, by eliminating any play between blocks and, on the other hand, to achieve a linear continuity of the joints, while being a simple implementation and manufacturing.
  • the block of self-locking concrete provided on its longitudinal and transverse edges with means spacers, arranged on either side of spacers said spacers being arranged between the means and spacers cooperating, by form, with said means distancers neighboring blocks, during the interpenetration of the pavers in the laying position, is characterized in that the distance means are each constituted by a pair of vertical tabs with a polygonal base or a portion of a circle projecting from the edge of the pavement and whose apex is in the form of a truncated pyramid or portion of a truncated cone, and in that said vertical tongues delimit between them, on the edge of the pavement, a vertical recess of constant section and of receiving a corresponding spacer protruding on the edge of the neighboring pavement
  • FIGS. 1 and 2 appended drawings are a self-blocking paver 1 made of concrete intended to be laid on traffic lanes, parking areas or other.
  • This block 1 is provided on its longitudinal edges 2 and transverse 3 with distance means 4, arranged on either side of spacers 5, arranged between the distance means 4 and cooperating, by form, with said means 4 spacers neighboring blocks, during the interpenetration of the pavers in the laying position ( figure 4 ).
  • the distance means 4 are each constituted by a pair of vertical tongues 41 having a polygonal base or a portion of a circle projecting from the edge of the pavement and whose apex is in the form of a truncated pyramid or portion of truncated cone, and in that said vertical tabs 41 delimit between them, on the edge of the block 1, a vertical recess 42 of constant section and receiving a corresponding spacer 5, projecting from the edge of the block neighbour ( Figures 1 to 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.
  • 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 ).
  • 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.
  • each distance means 4 is in contact, by the vertical tongues 41, on the one hand, with a spacer 5 and, on the other hand, with a longitudinal edge 2 or transverse 3 of a neighboring block 1 .
  • This arrangement of the distance means 4 and the spacers 5, projecting on the transverse edges 3 and the longitudinal edges 2 of the blocks 1 allows to obtain a linear continuity of the joints between the blocks 1, said spacer means 4 and spacers 5 s extending entirely into the jointing space between pavers 1.
  • the gap 7 delimited between the truncated pyramid-shaped peaks or truncated cone portion of the tongues 41 defines a corner filled with grouting sand preventing tearing of pavers 1 laid.
  • the distance means 4 and the spacers 5 advantageously have a height less than that of the block 1, their vertex preferably extending below the level of the upper edge of said block 1.
  • At least one spacer 5 of each longitudinal edge 2 and transverse 3 has a degressive section from the base of the block 1 to the upper end of the spacer 5, thus determining, with the vertical recess 42 delimited between the vertical tongues 41 of the corresponding spacing means 4, a vertical gap 6 'forming a grouting space by sand, with a progressive section from the lower face of the blocks 1 towards their upper face, producing a self compression under a pulling or sagging effort.
  • the filling of grouting sand not only achieves a stabilization of the blocks in the horizontal plane, but also forms a means of self-locking in cooperation with the distance means 4 and the spacers 5.
  • 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 spacers 5 and distance means 4, which has the effect a simultaneous compression of the grouting sand, this compression being effected, in fact, in cascade and resulting in a total blocking preventing tearing.
  • the blocks 1 can not move in a horizontal plane, because, on the one hand, the interpenetration of the distance means 4 and spacers 5 and, on the other hand, because of the filling of vertical interstices 6 by the grouting sand, which prevent pivoting of the blocks 1 relative to each other and, in this way, tearing or sagging, especially mechanically.
  • the block 1 is provided, on at least two opposite faces of the longitudinal edges 2 and / or transverse 3, at least one distance means 4 ', at least one vertical tongue 41' is shorter than the vertical tongues 41 of the means 4 spacers and whose apex extends to a level lower than that of the vertical tongues 41, determining a corresponding vertical gap 7 'between the vertical tongue 41 of the means spacer 4 previous and that (tab) 41', of the distance means 4 '.
  • a distance means 4 'of smaller height is advantageously provided at one end of each longitudinal and transverse edge 3 3, the corresponding end of the transverse edge 3 and longitudinal 2 being provided with a succession of spacers 5 and means distance 4 ( Figures 1, 3 and 5 ).
  • the figure 5 represents, hatched, the distance means 4 and 4 ', and the stiffeners 5 of a block, while the spacer means 4 and 4' and the stiffeners 5 of the other block are shown with a grid mark. The difference in height between the tongue 41 'of the distance means 4' and that of the tongue 41 adjacent is thus very clearly visible.
  • At least one tongue 41 'of a block cooperates with a tongue 41 of the neighboring associated block.
  • the top of the tongue 41 stopping at a level higher than that of the tongue 41 'thus leaving a larger rectangular base forms a kind of asymmetrical funnel for the flow of grouting sand.
  • this block can be achieved by implementing the usual molding techniques, that is to say with the use of a single mold, monobloc, and the pose is also achievable simply and quickly.
