CONCRETE PAVE OR THE LIKE FOR CARRYING OUT A

WALL COATING BY RECIPROCALLY RECIPROCTED PAVES

ADJACENT

The present invention relates to a slab or slab of concrete or material having similar characteristics, used in particular for the realization of flooring. More specifically, the invention relates to pavers or concrete slabs having protrusions and peripheral recesses for reciprocal interlocking paversou slabs juxtaposed.

Among a number of known embodiments, there may be mentioned, for example, tessellations made using concrete blocks or analogous materials, having a rectangular base and an upper part, generally rectangular, whose longest sides are formed by a completeususoid, the two longitudinal sinusoids being symmetrical with respect to the longitudinal axis of the block while the shorter sides are formed by a half-sinusoid. These blocks can fit into each other by simple translations made according to their axelongitudinal.

These pavers or slabs may be placed on a bed of sand, without the need for binders or rigid foundations, given their reciprocal nesting. Indeed, because of this interlocking, the charges applied to an element are transmitted to those surrounding which ensures the mechanical strength of the coating.

These pavers are mainly used for the construction of road pavements where the forces or loads are particularly important, such as loading docks, areas with heavy overload, or used where the foundation of the track can not have all the desired rigidity.

These blocks however have some disadvantages.

Rectangular bases are aligned during paving, creating a straight line between the bases of each paver alignment. The repeated passages of heavy vehicles directly above this vacuum cause in the long run a tilting effect of the elements constituting these alignments. The application of a vertical load on the protruding ends of a pad tends to cause a reversal effect of the item, since the charge is not supported by the base of the item, but by the edge of the base of the juxtaposed element.

The transverse joints arranged perpendicularly to the track cause, at the passage of the two or four-wheeled vehicles, a vertical repetition causing vibrations which are detrimental to the comforter.

Longitudinal sinusoids are of short wavelength, the passage of the joints, in their axis, by narrow-tire machines cause side vibrations alternatives compromising dangerously lastly the machine.

Some parts of the paver are overhanging with respect to the base, which may cause certain flatness defects in the rolling surface during demolding.

The present invention tends to provide a pavement or slab that does not negotiate under the effect of a repeated passage of heavy vehicles or under a punching load effect, regardless of where it isappliquée. Greater flatness of the running surface is furthermore guaranteed by the conformation of the pavement according to the invention. For this purpose, the invention relates to a paver, made of concrete or the like, for producing a track covering by reciprocal interlocking of paving stones, the edges of the upper surface of the pavement being constituted by sinusoidal arches, characterized in that it comprises in its thickness: - an upper zone, which in plan view is in the general shape of the network, bordered laterally and symmetrically with respect to its axelongitudinal by two sinusoids each extending practically over a wavelength, the two sinusoids moving away at most to one another on the transverse axis of the block and approaching the maximum of each other at both ends of the longitudinal axis of the block, a bottom or base area, the contour has generally the shape of a rhombus, whose axes coincide in vertical projection withthat of the upper zone, the transverse axis of the rhombus being shorter than the transverse axis of the upper zone, and the longitudinal axis of the rhombus 5 being longer than the longitudinal axis of the upper zone, the base zone presenting in the vicinity of the transverse axis a transverse extension limited by the outer contour of the upper zone, and an intermediate zone, located between the upper zone and the base zone, to ensure the connection between the contour of the upper zone and the contour of the base zone.

The block according to the invention is also remarkable in that: the intermediate zone is limited laterally by curved surfaces connecting the points of the spindle contour of the upper zone to the points of the generally rhombic contour of the lower zone; paved on the longitudinal axis are limited by transverse end walls perpendicular to said longitudinal axis, - the length of the pavement is less than the length of a sinusoid and the longitudinal dimension of the transverse extensions is equal to the difference between the length of a sinusoid and the length of the pavement, 2o - the transverse extensions have a transverse dimension at least equal to half of the transverse dimension of the transverse wall of extremity in the lower zone of the pavement, - the side walls of the upper zone and the lower dupavé area have a draft to allow a manufacturing by molding The clearance provided on the walls of the lower zone is of greater angle than that strictly necessary for the molding of the paving stone to allow the paving sand to rise between the paving stones, which contributes to ensuring good stability. of the paving, the intermediate zone consists of portions which connect the lower zone to the upper zone in a portion of the pavement for which the lower zone is wider than the said upper zone, and are therefore visible when the pavement is viewed by the top, and portions that connect the lower zone to the upper zone in a portion of the block for which said lower zone is narrower than said upper zone and are therefore visible when looking at the pavement from below. The invention will be better understood from the description which follows, given by way of nonlimiting example with reference to the appended drawings in which: FIG. 1 is a top view of a block according to the invention, FIG. a view from above of a paving made with cobblestones as that shown in FIG. 1; FIG. 3 represents the section of paving of FIG. 2 along line III-III; FIG. 4 represents the pavement of FIG. seen along the arrow IV of Figure 1, - Figure 5 shows the pavement of Figure 1 seen along the arrow V of Figure 1.

The block according to the invention comprises in its thickness: an upper zone 10 following a spindle contour 1, a lower zone 20, or base zone, in a globally diamond-shaped outline, an intermediate zone 30 situated between said zones; upper and lower areas for connecting the outlines of these areas.

These three zones are better visible in FIGS.

The generally spindle-shaped contour 1 of the upper surface, intended to form a rolling surface, of the block is visible in FIG.

This spindle contour 1 consists of two sinusoids 11 and 12 each extending substantially over a wavelength. The sinusoids 11 and 12 move away from each other on the transverse axis of the paddle and meet on the longitudinal axis of the pavement.

The sinusoids 11 and 12 have the same dimensional characteristics and are arranged symmetrically with respect to the longitudinal axis of the block. Their x-axis X 1 and X 2 are arranged starting from the longitudinal axis of the block and equidistant from it in such a way that the transverse dimension of the block is equal to the doubling of the total amplitude in ordinate of a sinusoid.

The length of the pavement is less than the length of a sinusoid 11,12 to provide a pavement that does not have tapered tips that can not withstand the release of the pavement during its manufacture, thedifferent manipulations to which it is subjected, the efforts of settlement during the making of the pavement and the efforts due to the rolling of the vehicles. Note 1 the length separating at each end of the block, the meeting point of the inusoid 11 and 12 of the end wall of the block.

The lower zone 20 of the pavement intended to form the base by which the paving stone is supported on the ground to be paved has the outline 2 whose shape is globally that of a rhombus.

The longitudinal and transverse axes of the lower zone 20 and the upper zone 10 of the pavement coincide in vertical projection.

The longitudinal and transverse dimensions of the lower zone are the same as the longitudinal and transverse dimensions of the upper zone.

The rhombus generally forming the contour 2 has a transverse dimension shorter than the transverse dimension of the upper zone of the pavement, and a longitudinal dimension which is greater than the longitudinal dimension of the pavement.

If we consider the contour 2 of the lower zone, we find that the longitudinal ends of the rhombus whose contour marries globally the shape are truncated while the transverse ends of the rhombus diamond are provided with transverse extensions 22.

The longitudinal dimension of the transverse extensions 22 is 21, it is therefore equal to the difference in length existing between the length of a sinusoid and the length of the pavement.

The transverse extensions 22 have a transverse dimension L at least equal to half the transverse dimension 2L of the end paroitransversale 23 in the lower zone of the pavement. 010810 6

These dimensions make it possible, during the constitution of a pavement, to position the paving stones against each other with the transverse extensions 22 of one bearing against the walls of the other end 23.

Referring to Figure 2 on which there is shown a paver realized with the pavers of the invention, and numbered these paving stones, it is understood that the longitudinal extensions 22 of the pavers I and III are supported by their end surface. against each other and by their lateral faces against the end wall 23 of the pavement II. Similarly, said block II is supported by lateral sonextension 22 against the lateral extension of the pavement IV and against the paroid'extrémité pavé III.

This arrangement makes it possible to carry out a tiling in which the linoids 11, 12 of the neighboring blocks are positioned relative to each other to form a sinusoid extending over a large number of wave lengths, the bulged parts, disposed above longitudinal extensions of a keypad, sinusoids completing the final sinusoid in the truncated end zones of neighboring cobblestones.

The intermediate zone 30 consists of curved surfaces connecting the points of the spindle contour 1 of the upper zone 10 to the generally diamond-shaped points 2 of the lower zone 20.

The portions 31 of the intermediate zone 30 connect the lower zone 20 to the upper zone 10 in a portion of the pavement for which the lower laditzone is wider than said upper zone, they are therefore visible when viewed from the pavement from above. The portions 32 connect the lower zone 20 to the upper zone 10 in a portion of the pad for whichthis lower zone is narrower than said upper zone and are therefore visible when looking at the pad from below.

These inclined surfaces 31, 32 have been shown by tilted hatches in Figures 4 and 5 while the substantially vertical surfaces bordering the tile are shown with vertical hatching.

The section, represented in FIG. 3, of the pavement of FIG. 2 makes it possible to better visualize the different inclinations of the intermediate zone 30 as a function of the considered location of the periphery of the pavement. 7 010810

When placing the blocks against each other to form a tiling, the inclined surfaces 31 and 32 of said blocks are positioned in abutment on each other which makes it possible to wedge the foot with respect to each other. Each portion of block corresponding to a portion 32 for which the upper zone 10 is wider than the lower zone 20 and is therefore cantilevered away from the ground issupported by a portion 31 pressing on the ground of the neighboring block.

As shown in the drawing, particularly in Figures 4 and 5, the side walls of the upper zone and the lower zone of the pavement are not vertical, they have a draft to allow a manufacturing by molding.

The clearance provided on the walls of the lower zone 20 is more important than the angle strictly necessary for molding the paving stone to let go back in the cobblestones sand on which is performed washing, which helps to ensure good stability of paving.

The pavement according to the invention then proposes a sinusoidal to undulating joint disposed obliquely with respect to the axis of the track, which makes it possible to eliminate the lateral vibrations which are detrimental to the handling of two-wheeled vehicles.

The total elimination of transverse joints makes it possible to further improve ride comfort and to approach that of a paved road.

Moreover, the distribution of the punching charges on the surrounding elements, with the resulting decrease of the ausol pressure reduces the resistance to require basecoats or foundation.
