Description

Title of the invention: Paving stone with spacers

[0001] The present invention relates to the field of building blocks for floor coverings, such as slabs or paving stones, and more particularly to the field of manufacturing such building blocks.

[0002] Soil urbanization generally results in the mineralization of surfaces, which can be achieved by laying paving stones or slabs. This mineralization allows for surfaces with a relatively constant, uniform flatness that is resistant to deformation under repeated stresses or forces caused by impacts from repeated pedestrian or even vehicle traffic, particularly when environmental humidity becomes significant. However, a drawback of this surface mineralization is the barrier it creates to the flow and infiltration of rainwater into the soil by producing low-permeability or even completely impermeable floor coverings. Rainwater is then drained by runoff down a slope of this surface to a system specifically designed for its evacuation.Conversely, in the absence of a slope, this water is forced to accumulate on mineral surfaces or even stagnate there until it evaporates, so that these ground surfaces are likely to become impassable for a pedestrian or even possibly for a vehicle.

[0003] Often, runoff rainwater, particularly when its flow rate exceeds a certain threshold, carries with it debris, litter, or simple dirt present on mineral surfaces. It is therefore necessary that drainage systems be adequately maintained to ensure their effectiveness and prevent blockages that could lead to accumulation or overflow.

[0004] The present invention aims to overcome these drawbacks by proposing a paving solution which allows efficient drainage of water and runoff on mineralized surfaces while preserving the qualities of a floor surface covering obtained by an arrangement of classic paving stones.

[0005] The present invention relates to a paving stone comprising a main body of polygonal shape which has several lateral surfaces, characterized in that the paving stone also comprises at least one spacer projecting on each lateral surface of the main body, each spacer comprising a flat lateral surface parallel to the lateral surface of the main body to cooperate with a spacer carried by a juxtaposed analogous paving stone,

[0006] and in that, in a horizontal plane in section, the different spacers of the paving stone have an identical protruding thickness so that the flat lateral surfaces The respective spacers define respective planes of lateral surfaces of a polygonal volume whose shape is identical to the polygonal shape of the main body of the cuboid.

[0007] The invention also relates to a pavement comprising at least two pavers according to the invention, characterized in that two of the at least two pavers are arranged in contact with each other at the level of at least a portion of the flat lateral surface of at least one spacer of the respective lateral surfaces opposite each of the main bodies of the juxtaposed pavers.

[0008] The invention will be better understood from the following description, which relates to preferred embodiments, given by way of non-limiting examples, and explained with reference to the accompanying schematic drawings, in which:

[0011] [Fig.3] is a schematic illustration of an example of a pavement combining examples of trapezoidal pavements according to the invention comprising spacers that have different thicknesses,

[0012] [Fig.4] is a schematic illustration of different examples of paving combining trapezoidal pavers according to the invention comprising spacers having identical thicknesses.

[0013] The invention relates to a paving stone 1 comprising a main body 11 of polygonal shape having several lateral surfaces 111, 112, 113, characterized in that the paving stone 1 also comprises at least one spacer 12 projecting from each lateral surface 111, 112, 113 of the main body 11, each spacer 12 comprising a flat lateral surface 121 parallel to the lateral surface 111, 112, 113 of the main body 11 to cooperate with a spacer carried by a similar juxtaposed paving stone,

[0014] and in that, in a horizontal plane in section, the various spacers 12 of the paving stone 1 have an identical projecting thickness such that the respective flat lateral surfaces 121 of the spacers 12 define respective planes of lateral surfaces 21 of a polygonal volume 2 whose shape is identical to the polygonal shape of the main body 11 of the paving stone 1.

[0015] In the context of the invention, the block 1 is configured so that, thanks to the presence of one or more spacers 12, the lateral surfaces 111, 112, 113 of the main body 11 of the block 1 remain held positioned at a distance from the surface lateral of a similar juxtaposed block. The polygonal volume 2 of each block 1 according to the invention, defined in particular by the lateral surfaces 121 of the various spacers 12 of the blocks 1, thus constitutes a volume comprising, on the one hand, a solid volume formed by the main body 11 and the spacers 12 of the block 1 and, on the other hand, an empty volume formed by recessed areas at the level of the lateral surfaces 111, 112, 113 of the main body 11. Along a surface of the block 1, the total length of at least one spacer 12 is less than that of the lateral surface 111, 112, 113 of the main body 11, so that the recessed areas of the polygonal volume 2 create at least one surface continuity, in particular through one of the lateral surfaces 111, 112, 113 of the main body 11, between the two surfaces, upper and lower, of the same block 1.

[0016] Furthermore, within the framework of the invention, the contact of the block 1 with an adjacent block is achieved more particularly by bringing the polygonal volumes of each of the adjacent blocks 1 into contact such that these polygonal volumes are in contact with each other at a plane shared by the lateral surfaces 21 of these polygonal volumes 2. Under these conditions, the juxtaposition of two blocks 1 and their respective polygonal volumes 2 allows the creation, by means of at least one spacer 12, of one or more openings 3 between the two adjacent blocks 1. These openings 3 then create a junction between the two surfaces, upper and lower, of the blocks 1 and therefore of the pavement. In the context of precipitation, the rainwater present on the upper surface of the paving 1 is then able to flow down the height of one of the lateral surfaces 111, 112, 113 of the main body 11 which forms the inner surface of one of the openings 3.It should be noted that the quality of rainwater drainage from the upper surface of the paving stone 1 and through these openings 3, made available by the spacers 12 between two juxtaposed paving stones 1, is notably improved by increasing the cross-sectional dimensions of the openings 3 and therefore by increasing the thickness of the spacers 12 and / or the spacing between the lateral surfaces 111, 112, 113 of the main body 11 and the lateral surface 21 of the corresponding polygonal volume 2. According to a preferred construction example, the spacers 12 are made so that their thicknesses are between 2 and 20 millimeters, preferably on the order of 15 millimeters.

[0017] According to an example relating to a particularity of the spacers 12, their position on the relevant lateral surface 111, 112, 113 of the main body 11 of the block 1 is located at a distance from the end of the corresponding lateral surface 21 of the polygonal volume 2 of the block 1. Such a positioning of the spacers 12 allows the creation of openings 3 at the junction level, in a pavement, between more than two juxtaposed blocks 1, in particular at the corners of the polygonal volumes 2 of the blocks 1.

[0018] It should be noted that the free volumes of the polygonal volume 2 of the block 1 are created by the various openings 3 made possible by at least one spacer 12 Positioned on the lateral surfaces 111, 112, 113 of the main body 11 of the paving stone 1, the spaces can be filled, at least partially, with a material selected not to impede the drainage of rainwater from the upper surface of the paving stone 1 along the height of at least one of the lateral surfaces 111, 112, 113 of the main body 11 of the paving stone 1. For example, this material could be at least one material that forms or contributes to the formation of the bed on which the paving stone 1 of the invention is positioned on the ground. Similarly, for example, this material could be sand, a silicate such as a zeolite or equivalent, soil, or even natural vegetation such as mosses and / or grasses or plants, or even a combination of several of these materials or of materials with equivalent properties.

[0019] Preferably, if not conventionally, the upper and / or lower surfaces of a paver 1 are arranged to be in parallel planes and, generally, configured to be in substantially horizontal planes when the paver 1 is installed on site. Also, according to an example relating to a variant of the construction of the paver 1 according to the invention, the lateral surfaces 121 of the various spacers 12 of the pavers 1 are arranged in vertical planes substantially perpendicular to the plane of the upper and / or lower surfaces of the paver 1.In this preferred construction variant, the lateral surfaces 121 of the various spacers 12 are compatible with surfaces supported by similar paving stones and allow for the support and transmission of forces, stresses, or tensions through the paving stone 1 in a substantially horizontal plane. These forces are then substantially balanced or distributed homogeneously over the entire contact area of ​​the lateral surfaces 121 of the spacers 12, thus limiting or even eliminating the risk of displacement by tilting or tipping of the paving stone 1. It should also be noted that since the lateral surfaces 121 of the various spacers 12 of the paving stones 1 form contact and support surfaces against the lateral surfaces of adjacent paving stones, it is not necessary for the lateral surfaces 111, 112, 113 of the main body 11 of the paving stone 1 to be arranged in vertical planes and / or parallel to the vertical lateral surfaces 121 of the spacers 12.

[0020] According to an example relating to another construction variant of the block 1 according to the invention and capable of being combined with either of the variants detailed above, at the level of at least one of the lateral surfaces 111, 112, 113 of the main body 11, at least one spacer 12 is positioned such that, in a horizontal plane in section, at least a portion of the flat lateral surface 121 of the spacer 12 is positioned at the center of the corresponding lateral surface 21 of the polygonal volume 2. This positioning of at least a portion of the surface 121 of the spacer 12 at the center of the lateral surface 21 of the volume 2 The polygonal design ensures the presence of at least one point of contact at a geometric equilibrium point of the polygonal volume 2 in which the block 1 of the invention is inscribed. When bringing two blocks 1 into contact, it is preferable that the surfaces 21 of the respective polygonal volumes 2 brought into contact have substantially identical or equivalent widths. Therefore, a contact portion of the surface 121 of the spacer 12, positioned at least at the center of the lateral surface 21 of the polygonal volume 2, guarantees contact between two spacers 12 supported by different blocks and whose lateral surfaces 121 have different widths. It should be noted that this arrangement, specifically positioning at least a portion of the lateral surface 121 of a spacer 12, is particularly relevant in the context of lateral surfaces 111, 112 of a main body 11 of a block 1 provided with a single spacer 12.Also, when two lateral surfaces 111, 112 of paving stones 1, which each carry only one spacer 12, are positioned opposite each other, this particular construction of the paving stones 1 ensures that the respective spacers 12 of these paving stones 1 are able to share a contact surface made by at least the portion of the lateral surface 121 of the spacers 12 positioned at the center of the lateral surface 21 of contact of the respective polygonal volumes 2 of the paving stones 1. In addition, it can be noted that the construction of a contact surface of a spacer 12 positioned centrally at the level of the lateral surface 21 of the polygonal volume 2 contributes, at the level of the lateral face of the paving stone 1, to the balancing of the transfer of force or effort in a plane substantially parallel to the plane of the upper and lower surfaces of the paving stone 1 and / or the pavement which incorporates this paving stone 1.Therefore, the risks of pivoting of block 1 in such a plane are reduced, or even eliminated.

[0021] According to an example relating to another construction variant of the paving 1 according to the invention and capable of being combined with one or the other of the variants detailed above, in a horizontal plane in section, at the level of at least one of the lateral surfaces 111, 112, 113 of the main body 11, the ratio between, on the one hand, the length of the flat lateral surface 121 of at least one spacer 12 and, on the other hand, the length of the corresponding lateral surface 111, 112, 113 of the main body 11 is in a range between 0.25 and 0.5, or preferably on the order of 0.33. Such proportions of the length of the flat lateral surface 121 of at least one spacer 12 make it possible to guarantee the paving 1 according to the invention the combination of two properties whose optimal qualities are obtained by antagonistic technical solutions.This combination of properties of the paving stone 1 thus relates, on the one hand, to a sufficient quality of drainage through the openings 3 present along at least one lateral surface 111, 112, 113 of the main body 11 and, on the other hand, to ensuring a quality of stability of the paving stone 1 at the level of the surface. lateral 121 of the spacer 12 forming contact with a juxtaposed block, this stability allows to support and transmit forces, stresses or tensions, in a substantially horizontal plane, through the block 1 while limiting the risk of displacement of the block in this plane.

[0022] According to an example relating to another construction variant of the paving 1 according to the invention and capable of being combined with either of the variants detailed above, in a horizontal plane in section, at the level of at least one of the lateral surfaces 111, 112, 113 of the main body 11, the ratio between, on the one hand, the length of the flat lateral surface 121 of at least one spacer 12 and, on the other hand, the length of the corresponding lateral surface 21 of the polygonal volume 2 is in a range between 0.25 and 0.5. As with the previous construction variant, such proportions of the length of the flat lateral surface 121 of at least one spacer 12 make it possible to guarantee the paving 1 a combination of two properties whose optimal qualities are achieved by antagonistic technical solutions.This combination of properties of the paving stone 1 thus relates, on the one hand, to sufficient drainage quality through the openings 3 present along at least one lateral surface 111, 112, 113 of the main body 11 and, on the other hand, to ensuring the stability of the paving stone 1 at the lateral surface 121 of the spacer 12 forming contact with an adjacent paving stone, this stability allowing it to support and transmit forces, stresses or tensions, in a substantially horizontal plane, through the paving stone 1 while limiting the risk of displacement of the paving stone in this plane.

[0023] According to an example relating to another construction variant of the paver 1 according to the invention and capable of being combined with either of the variants detailed above, at least one spacer 12 is projecting over the entire height of the lateral surface 111, 112, 113 of the main body 11 of the paver 1 which carries this spacer 12. Such an arrangement of the spacer 12 over such a height makes it possible to operate an optimized contact between the lateral surface 121 of the spacer 12 of the paver 1 and an adjoining paver so that any forces, stresses or tensions in a substantially horizontal plane are distributed through the spacer 12 over the entire height of the paver 1. The risk of a possible tilting of the paver 1 around a horizontal axis is thus limited, if not eliminated.

[0024] According to an example relating to another construction variant of the paving 1 according to the invention and capable of being combined with either of the variants detailed above, at least one spacer 12 projects to a height less than the height of the lateral surface 111, 112, 113 of the main body 11 which supports it, so that, in a vertical plane in section, the level of the upper surface of the spacer 12 is positioned below the level of the upper surface of the body main body 11 of paving 1. According to this embodiment, a gap forming a space is arranged between, on the one hand, the upper surface of the spacer 12 and, on the other hand, the upper surface of the main body 11 of paving 1. It should be noted that within this arrangement, the polygonal volume 2 of paving 1 left free can be filled, at least partially, by a material selected so as not to impede the drainage of rainwater from the upper surface of paving 1 along the height of at least one of the lateral surfaces 111, 112, 113 of the main body 11 of paving 1. Also, the space left free between the upper surface of the spacer 12 and the level of the upper surface of the main body 11 of paving 1 can be filled by such a material allowing drainage, for example, down to the level of the upper surface of the main body 11 of paving 1.In this way, within the framework of a pavement incorporating a paver 1 of the invention, the surface of the pavement presents a combination of the upper surfaces of the main bodies 11 of the paver 1 and materials allowing rainwater drainage. For an observer positioned above the upper surface of the paver 1, the drainage material is thus distributed around the perimeter of the upper surface of the main body 11 of the paver 1, at the level of the upper surface of the polygonal volume 2 of the paver 1, such that this drainage material forms a junction material between the paver 1 and a second juxtaposed paver positioned in contact by at least one spacer 12 of a paver 1 according to the invention.According to such an arrangement, the upper surface of the spacer 12 covered by the material allowing water drainage into the depth of the soils is masked so that the spacer 12 is no longer visible to an observer positioned above the upper surface of the paving stones 1. Preferably, the ratio between the height of the spacer 12 and the height of the lateral surface 111, 112, 113 of the main body 11 of the paving stone 1 which carries this spacer 12 is at least 0.5, ideally greater than 0.7, ideally greater than 0.8.

[0025] According to an example relating to another construction variant of the paving stone 1 according to the invention and capable of being combined with either of the variants detailed above, the paving stone 1 comprises a main body 11 of hexagonal shape and, in a horizontal plane in section, the various spacers 12 of the paving stone 1 having an identical protruding thickness, the respective flat lateral surfaces 121 of the spacers 12 define respective planes of lateral surfaces 21 of a hexagonal volume 2 whose respective angles are identical to the angles of the main body 11 of the paving stone 1. Such a hexagonal configuration of the paving stone 1 allows, when the hexagonal shapes are regular, i.e. with identical side lengths, the creation of a pavement by a single type of paving stone 1 and in which the entirety of a ground surface is able to be covered by paving stones 1.Furthermore, in the context of a pavement made with hexagonal-shaped paving stones, . Each block 1 is inserted laterally by one of its corners between two other adjacent blocks 1, at the 60° angle formed by the respective surfaces of these two adjacent blocks 1. This arrangement ensures cohesion among the individual blocks 1 in a pavement by facilitating the transmission of forces, stresses, or tensions in a substantially horizontal plane through the blocks 1 of the pavement, thus limiting, if not preventing, the risk of displacement of the blocks 1 in such a plane.

[0026] According to an example relating to another construction variant of the paving 1 according to the invention and capable of being combined with either of the variants detailed above, in a horizontal plane in section, the paving 1 comprises a main body 11 of trapezoidal shape comprising, on the one hand, two parallel lateral surfaces 111, 113 and, on the other hand, two lateral surfaces 112 of identical length, so that the main body 11 comprises a vertical plane of symmetry passing through the centers of two parallel lateral surfaces 111, 113 and, in a horizontal plane in section, the various spacers 12 of the paving 1 having an identical protruding thickness, the respective flat lateral surfaces 121 of the spacers 12 define respective planes of lateral surfaces 21 of a trapezoidal volume 2 whose respective angles are identical to the angles of the main body 11 of the paving 1.Such a trapezoidal configuration of the block 1 allows a juxtaposition of two blocks 1 by respective lateral faces of identical or similar lengths, so that the juxtaposition of these two trapezoidal blocks 1 creates a hexagonal assembly allowing us to benefit from the essential properties provided by hexagonal blocks 1 such as detailed in particular for the previous construction example, while including, with an identical pavement surface, an additional drainage zone located at the junction of the two trapezoidal blocks 1, that is to say across the hexagonal arrangement made by these two blocks 1.This junction between the two trapezoidal blocks 1 is thus achieved by at least one spacer 12 carried by the lateral surface of at least one of the two juxtaposed blocks 1, ideally by the spacers 12 carried by each of the lateral surfaces of the two blocks 1 positioned opposite each other.

[0027] According to an example relating to a variant of the construction of a trapezoidal-shaped block 1 according to the invention, at the level of the two parallel lateral surfaces 111, 113 of the main body 11, on the one hand, in a horizontal plane in section, the longer lateral surface 113 comprises two spacers 12 positioned symmetrically with respect to the vertical plane of symmetry of the trapezoidal arrangement of the block 1 and, on the other hand, in a horizontal plane in section, the shorter lateral surface 111 comprises a single spacer 12, at least a portion of whose lateral surface 121 is positioned at the center of the surface 21 corresponding lateral surface of the trapezoidal volume 2. According to this construction variant, the longer lateral surface 113 includes, between the two spacers 12 it carries, a gap capable of creating an opening 3 for drainage and rainwater runoff. The symmetrical arrangement of the spacers on the longer lateral surface 113 allows for easy positioning opposite the spacers 12 carried by the corresponding lateral surfaces 113 of two juxtaposed pavers 1 when the lateral surfaces 21 of the respective trapezoidal volumes 2 of these pavers 1 are positioned opposite each other.According to a preferred embodiment of this construction variant, at the level of the longer lateral surface 113, at least a portion of the flat lateral surface 121 of each of the spacers 12 is positioned at the center of one half of the lateral surface 21 defined by the vertical plane of symmetry of the block 1 passing through the centers of two parallel lateral surfaces 111, 113.This preferred embodiment of the spacers 12 on the longer lateral surface 113 allows for the juxtaposition of different trapezoidal pavers 1 similar or identical by their spacers 12 carried by the longer lateral surface 113 guaranteeing contact via the spacers 12, on the one hand, when the lateral surfaces 21 of the respective trapezoidal volumes 2 of these pavers 1 are positioned opposite each other and, on the other hand, when the lateral surfaces 21 of the respective trapezoidal volumes 2 of the juxtaposed pavers 1 are positioned with an offset along the axis of the lateral surfaces 121 of the spacers 12, this offset being on the order of half the length of the lateral surface 21 of the trapezoidal volume 2 at the level of the longer lateral surface 113 of the pavers 1.It should be noted that, within the framework of this preferred realization of the construction variant, this contacting of the juxtaposed paving stones 1 by their respective spacers 12 is effective independently of the respective lengths of the spacers 12, even if the respective lengths of the spacers 12 are different between the paving stones 1.

[0028] Furthermore, a trapezoidal block 1, according to the construction variant detailed in the preceding paragraph, also comprises parallel and opposite lateral surfaces 111, 113 of the main body 11 with a distribution of spacers 12 which makes it incompatible, along an axis of symmetry shared by two similar juxtaposed blocks 1, to position a longer lateral surface 113 of a first block 1 opposite the shorter lateral surface 111 of the second block 1. Within such a distribution of spacers 12, the lateral surfaces 121 of the spacers 12 are likely to encounter difficulties in interacting by bearing against each other. This difficulty in interaction thus limits the positioning possibilities of the paving stones 1 between each other in the context of the creation of a pavement and therefore to guide an operator in the handling of such paving stones 1 on a laying site.

[0029] According to an example relating to another construction variant of a paving 1 according to the invention of trapezoidal shape and capable of being combined with one or the other of the variants previously detailed, in a horizontal plane in section, at the level of the two parallel lateral surfaces 111, 113 of the main body 11, the ratio between, on the one hand, the longer lateral surface 113 and, on the other hand, the shorter lateral surface 111 is 2. Such a construction variant allows a multiplication of the arrangement possibilities of the paving 1s of similar trapezoidal shape by their longer lateral surfaces 113.Thus, positioning the shorter lateral surface 111 of a first block 1 opposite one half of the longer lateral surface 113 of a second block 1 leaves the second half of this lateral surface 113 free for the positioning of a possible third block 1. This third block 1 is then inserted at the angle formed by the first two blocks 1 resting against each other. According to a preferred embodiment of this construction variant, at the level of the longer lateral surface 113, at least a portion of the flat lateral surface 121 of each of the spacers 12 is positioned at the center of one half of the lateral surface 21 defined by the vertical plane of symmetry of the block 1 passing through the centers of two parallel lateral surfaces 111, 113.In the context of a combination of this preferred positioning of the spacers 12, with a ratio of the lengths of the two parallel lateral surfaces 111, 113 of the main body 11 which is on the order of 2, in addition to the properties previously detailed, such trapezoidal blocks 1 also guarantee the contact of two blocks 1 via the spacers 12 as soon as one of the ends of the shorter lateral surface 111 of a first block 1 is placed opposite one of the ends of the longer lateral surface 113 of a second block 1.

[0030] According to an example relating to another construction variant of a trapezoidal-shaped block 1 according to the invention, which can be combined with either of the variants detailed above, in a horizontal plane in section, the trapezoidal shape of the block 1 is balanced, that is to say, the trapezoidal shape of the block 1 comprises, on the one hand, three lateral surfaces 111, 112 of identical lengths and, on the other hand, two parallel lateral surfaces 111, 113 such that the ratio between, on the one hand, the longer lateral surface 113 and, on the other hand, the shorter lateral surface 111 is 2. When the block 1 has a balanced trapezoidal shape, this allows for the positioning of the shorter parallel lateral surface 111 and the two opposing inclined lateral surfaces 112 of a first block 1 in vis-à-vis either of these same surfaces 111, 112 of a second similar paving stone 1. These arrangements of paving stones 1 together thus allow for a multiplication of possible paving patterns. Furthermore, given the identical length of the shorter parallel lateral surface 111 and the two opposing inclined lateral surfaces 112 in the different paving stones 1, contact via at least one spacer 12 carried by each of these surfaces is ensured by positioning at least a portion of the surface 121 of each of the spacers 12 at the center of each of the corresponding lateral surfaces 21 of the trapezoidal volume 2 in which the paving stones 1 are respectively inscribed.It should also be noted that such a configuration, using trapezoidal pavers 1, allows for full benefit from the properties offered by regular hexagonal pavers, while integrating, for the same paved area, an additional drainage zone located at the junction of the trapezoidal pavers 1. Thus, this variant of paver 1 construction according to the invention allows for the creation of a pavement using a single type of paver 1, and in which the entire ground surface can be covered by these pavers 1.

[0031] The invention also relates to a pavement comprising at least two pavers 1 according to the invention, characterized in that two of the at least two pavers 1 are arranged in contact with each other at the level of at least a portion of the flat lateral surface 121 of at least one spacer 12 of the respective lateral surfaces 111, 112, 113 opposite each of the main bodies 11 of the juxtaposed pavers 1.

[0032] Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications remain possible, particularly with regard to the composition of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.

5. Paver (1) according to any one of the preceding claims, characterized in that at least one spacer (12) is projecting to a height less than the height of the lateral surface (111, 112, 113) of the main body (11) which carries it so that, in a vertical plane in section, the level of the upper surface of the spacer (12) is positioned below the level of the upper surface of the main body (11) of the paver (1).

6. Paving stone (1) according to any one of the preceding claims, characterized in that, in a horizontal plane in section, at the level of the two parallel lateral surfaces (111, 113) of the main body (11), the ratio between, on the one hand, the longer lateral surface (113) and, on the other hand, the shorter lateral surface (111) is 2.

7. Paving comprising at least two pavers (1) according to any one of claims 1 to 6, characterized in that two of the at least two pavers (1) are arranged in contact with each other at the level of at least a portion of the flat lateral surface (121) of at least one spacer (12) of the respective lateral surfaces (111, 112, 113) opposite each of the main bodies (11) of the juxtaposed pavers (1).
