Definitions

• This invention relates to a stone for forming a pavement.
• each ground covering by means of stones is intended, whether public works are concerned for forming, for example, streets and places, or applications in the private sector, for example, for constructing driveways, terraces or the like. Also, it is not excluded to apply such pavement in roofed rooms.
• the invention relates to concrete stones, either poured concrete stones, or vibrated concrete stones, however, more in general it may also be applied with stones made of other basic materials.
• Such pavements can be made of classic concrete stones, more particularly clinkers, which, as known, show a regular shape.
• An advantage of such clinkers consists in that herewith, a pavement can easily be realized, simply by placing them onto a prepared sublayer, for example, a flat sand bed, next to each other and in contact with each other.
• a disadvantage consists in that with such clinkers no pavement having a natural appearance can be realized.
• the invention aims at a stone which, on one hand, may show an irregularly or particularly formed appearance at the upper side, for example, has an irregular shape which is an imitation of natural stone, and, on the other hand, can be laid as easily as regularly shaped clinkers, such that, to this end, no experienced and specialized person skilled in the art is necessary.
• the invention relates to a stone for forming a pavement, with as a characteristic that, on one hand, it has an irregularly or particularly formed upper portion and, on the other hand, is provided with means for laying such stone, together with other similar stones, in a regular manner.
• the laying of the stones then is determined by means of said means and not by the irregularly or particularly formed upper portion, such that, due to an appropriate design of these means, the stones still can be laid orderly against each other in a simple manner.
• said means consist of contact portions situated at the side of the stone, lower than the upper side of the stone, which portions determine a regular contour.
• said means consist of contact portions situated at the side of the stone, lower than the upper side of the stone, which portions determine a regular contour.
• said means consist of a regularly shaped portion which is situated beneath said irregularly shaped upper portion and, more particularly, is realized in the shape of a base.
• the stone preferably also has an upper portion, more particularly said irregularly shaped portion, which recedes laterally in respect to the portion situated therebeneath, in such a manner that, when laying this stone against similar stones, a joint is created next to the upper portions of these stones which is suitable for being filled by a filling agent, such as sand or another filling mortar.
• a filling agent such as sand or another filling mortar.
• the regularly shaped lower portion is hidden from view by the filled joints.
• the impression is created that the stones are lying loose from each other, whereas in reality they still are fixedly positioned against each other / as a result of which a mutual shifting is excluded.
• the receding portion preferably has an undercut, with as an advantage that the filling agent provided in said joint will be better retained.
• the undercut is realized such that, when laying such stone together with similar stones, so to speak, a reversed wedge-shaped joint opening is created, as a result of which a filling agent, for example, sand, or even a hardening filling mortar, provided therein is retained particularly well in this joint opening.
• a filling agent for example, sand, or even a hardening filling mortar
• the stone is provided at its side with portions which, when several of such stones are laid against each other laterally, guarantee for a passage for water, which portions, seen from the top downwards, start below the irregularly shaped portion and/or from the lower edge of the receding part.
• this portion only starts at a distance below the upper surface of the stones and the portion thereabove is intended for being filled with sand or such, the portions which have to guarantee the passage for water always are hidden from view, with as an advantage that these portions do not form a disturbing factor in the appearance of the obtained pavement surface, which indeed would be the case if such portions specifically should extend up to into the visible upper surface of the stone.
• the portions forming a passage for the water will consist of one or more grooves which are formed in one or more sides of said base.
• the invention thus also relates to a stone for forming a pavement, with as a characteristic that it comprises an upper portion with such a contour that along the side of the upper portion, in respect to the contour formed by the portion situated therebeneath, a receding portion is formed, such that, when laying this stone against similar stones, a joint is created next to the upper portions of these stones which is suitable for being filled with a filling agent.
• the upper portion thus also may have a regular design.
• the receding portion preferably is realized such that, when laying this stone together with similar stones, so to speak, reversed wedge-shaped joint openings are created.
• portions enhancing the passage of water between the respective stones which portions only start at a lower level, such that they always are hidden from view in respect to the pavement, also can be advantageous in combination with embodiments of stones of which the upper portion not necessarily, as aforementioned, has an irregular or particular shape.
• a stone for forming a pavement with as a characteristic that it comprises an upper portion with such a contour that around this upper portion, in respect to a contour formed by the portion situated therebeneath, a receding portion is formed, and that this stone is provided at its side with portions which, when several of such stones are laid next to each other, form a passage for water, which portions, seen from the top downward, start below said upper portion in order to extend up to the bottom of the stone.
• said irregularly shaped portion and/or said receding portion extends over a height, depth, respectively, of at least 0,5 cm and still better at least 1 cm, such that a joint filling can be safely guaranteed, even if it consists of loose sand.
• figure 1 in perspective represents a stone according to the invention
• figures 2 and 3 represent the stone from figure 1 in side view, top view, respectively
• figure 4 represents a portion of the pavement, formed of stones, such as represented in figures l to 3
• figure 5 represents a cross-section according to line V-V in figure 4
• figures 6 to 8 represent views analogous to those of figures 1 to 3 , for a variant
• figures 9 to 11 represent still another variant
• figures 12-13 and 14-15 represent another two variants
• figure 16 represents a particular form of embodiment.
• the invention relates to a stone 1 for forming a pavement 2, which, on one hand, comprises an irregularly or particularly shaped upper portion 3 and, on the other hand, is provided with means 4 which allow to lay such stone l, together with other similar stones 1, in a regular manner.
• the means 4 consist of contact parts 5 which are situated at the sides 6 of the stone 1, lower than the upper side 7 of the stone 1, whereby these contact parts 5 determine a regular contour 8, which in figure 3 is indicated in dashed line.
• These contact parts 5 consist of the side walls of a regularly shaped lower portion 9 which is situated beneath said upper portion 3 and which is realized in the shape of a base.
• the contour of the upper portion 3 is situated within said contour 8, as becomes clear from figure 3.
• the upper portion 3 has a portion 10 receding in respect to the lower portion 9.
• the receding portion 10 preferably is realized as an undercut, which is formed by a side 11 narrowing downward, such that when laying such stone l together with similar stones 1, so to speak, a wedge-shaped joint opening 12 is created, as can be seen in figure 5.
• the stone 1, at its side, more particularly at one or more sides, preferably is provided with portions 13 which, when several of such stones 1 are laid laterally against each other, guarantee a passage 14 for water, such as indicated in figure 5, which portions 13 start in downward direction beneath the irregularly shaped upper portion 3 and/or from the underside 15 of the receding portion 10.
• the portions 13 are formed by vertical grooves which are provided in the respective lateral faces 6.
• the height H over which the upper portion 3 and/or the receding portion 10 extend which also can be denominated as the depth of the joint opening 12, preferably is at least 0,5 cm and still better at least 1 cm.
• the stones 1 are provided on a, for example, flat sand bed 16, as this traditionally also is performed with classical clinkers. Hereby, they are simply positioned with their contact portions 5 against each other.
• the irregular design of the upper portions 3 does not form an obstacle for laying the stones 1 in a regular manner.
• relatively deep joint openings 12 are created, which, as aforementioned, preferably have a reversed wedge shape, or, defined more exactly, show a dovetail shape.
• this sand 17 hardly can leave the joint openings 12, such that the lower portion 9 in a guaranteed manner remains hidden from view. Due to the wedge shape, the sand 17 moreover is retained better in the joint openings 12.
• portions 13 also start at a relatively large distance, to wit a distance which coincides with the height H, under the upper side 7 of the stone 1, also always sand 17 or such will be present thereabove, as a result of which it is obtained that it is impossible for the portions 13 to disturb the appearance at the upper surface, when the joint openings 12 are filled in a normal manner.
• Figures 6 to 8 hereby show a stone 1 which is bent and wedge-shaped.
• Figures 9 to 11 show a variant whereby the lower portion 9 has a relatively small height and whereby the receding portion 10 is realized as a hollow part extending around the circumference.
• Figures 12 and 13 represent a variant whereby the irregularly shaped upper portion 3 at the top has a straight side, however, somewhat more downward has an inclined side 11 which then forms an actual undercut.
• FIG. 14 and 15 another variant is represented, whereby the upper portion 3 at its base connects to the lower portion 9, this contrary to the embodiments from figures 1 to 13, whereby the transition between the upper portion 3 and the lower portion 9 is step-shaped.
• Figure 16 shows that the contact parts 5 not necessarily have to consist of a massive base, but may also be realized as locally present elements, in this case, at the lower corners of the stone 1.
