EP2401432B1 - Paving stone having stone flanks oriented preferably perpendicular to the laying plane - Google Patents

Description

The invention relates to a paving stone with preferably aligned perpendicular to the laying plane stone edges, wherein on the stone flanks composite elements are formed, which correspond with composite elements of a stone flank of an adjacent stone.

A generic paving stone is from the DE 103 30 928 B4 known.

Paving stones, especially for road construction, are often designed as composite systems for reasons of displacement safety. These composite systems are based on the principle that arranged on a stone flank raster composite elements engage in the interstices of the arranged in grid composite elements on the edge of the adjacent paving stone to prevent in cooperation with the joint filling displacement of the stones against each other. Paving stones are widely used in which composite elements are arranged on all stone flanks in a predetermined grid, which mesh around each other, regardless of the position of the paving stones to each other. In this system, the stones have a defined top and bottom.

When laying the paving stones, it is desirable that the stones have as little as possible any contact with each other, but are separated from each other by grout. This ensures that that no damage due to temperature fluctuations and associated material expansions can occur.

From the EP 1 036 882 B1 It is known to provide artificial stones for paving purposes with composite sections, on which a spacer is arranged to ensure a minimum distance between the stones. In this case, the spacer is designed so that it is at least partially destroyed when shaking the laid patch.

From the DE 201 09 608 U1 For example, an artificial stone for paving purposes is known in which a section holder is applied to a composite section, so that the section holder abuts against the side edge of an adjacent paving stone, thereby ensuring a minimum joint between the composite sections. Furthermore, it is from the DE 201 09 608 U1 It is known that a spacer is applied directly to the side flank of a stone and cooperates with a composite element of an adjacent paving stone so that the composite element impinges on the spacer applied to the side flank, which in turn is intended to ensure a minimum joint.

From the DE 198 24 556 B4 a concrete paving stone is known in which two adjacent stone flanks have longer teeth than the other two adjacent stone flanks. In this case, the longer teeth on the respective opposite stone sides of the concrete paving stone depressions are assigned. This should be possible to change the gap width.

A disadvantage of the prior art systems is that these systems are not applicable to stones with larger dimensional tolerances, since the then required margins between the composite elements would lead to the addition of dimensional differences across several stones.

From the generic document a concrete paving stone is known which has composite elements with different widths. In this case, a composite element should have a width which substantially corresponds to the clear width between two adjacent, narrow composite elements of an adjacent paving stone. The space between two narrow composite elements should be greater by a multiple than the width of a narrow composite element. Furthermore, the number of narrow composite elements should be a multiple of the number of wide composite elements. By using composite elements of different widths, on the one hand, it should be achieved that, in the area of the narrow composite elements, large horizontal clearances are created between the composite elements of adjacent bricks, which create sufficient tolerance when juxtaposing stones of different sizes. On the other hand, two stones are to be selectively fixed against each other by the wider composite elements, which correspond in width to the clear width between two narrow composite elements. In this way, it should be prevented that dimensional differences or misalignment over several stones add up. At the same time, the resulting between the narrow composite elements wide chambers to allow the inclusion of coarser and more effective joint material in the joints. The wide composite element may optionally be provided with a buffer pocket which can receive pushed concrete material. In one embodiment of DE 103 30 928 A4 can be provided between two narrow composite elements a thickening. The thickening is intended to counteract a two-dimensional contact of two adjacent paving stones. Furthermore, it can be provided that one or more narrow composite elements are executed extended perpendicular to the stone flank and thus serve as projecting spacers.

A disadvantage of the generic document is that at the points at which a broader composite element between two narrow composite elements is introduced, no or not enough sufficient joint material, especially sand, can be introduced. This results in the generic document in that the wide composite element, so that this can fulfill its function, must be fitted as form-fitting as possible between two narrow composite elements.

The document DE 202004008747 U discloses a paving stone having the features of the preamble of claim 1.

The present invention has for its object to provide a paving stone, in which the contact surface between two adjacent paving stones is largely minimized and which allows that a suitable amount of joint material between two adjacent paving stones can be introduced, which is to be prevented Add dimensional differences or laying errors over several stones.

This object is achieved by the features of claim 1.

This object is also achieved by the features of claim 16.

The fact that the paving stone according to claim 1 on each flank has at least two embodiments of composite elements, which differ at least in that the composite elements of a configuration compared to the composite elements of the other embodiment are extended in a direction perpendicular to the stone flank, it is achieved that two do not touch adjoining paving stones over all composite elements, but only a contact over the extended composite elements. This minimizes the contact area between the stones. In particular, the stones are separated from one another by joint material, in particular sand, in the area of the non-elongated composite elements.

These features are implemented equally both in the inventive solution according to claim 1 and in the inventive solution according to claim 16.

In the inventive solution according to claim 1 is further provided that the formed on the stone flanks composite elements are each arranged in a grid, so that the composite elements each have an even horizontal distance to adjacent composite elements of the same stone flank. It is provided that all composite elements, regardless of whether it is normal or perpendicular to the stone flank elongated composite elements, are arranged in the predetermined grid. A predetermined grid dimension is to be understood as meaning that the composite elements each have a uniform, horizontal spacing of, for example, 25 mm to adjacent composite elements of the same stone sidewalls.

According to the invention, in each case at least two composite elements are offset within their position between two composite elements or a composite element and a vertical stone edge mirror images of each other so that the two composite elements are arranged outside the grid dimension. It should be located between the staggered composite elements at least one arranged in grid composite element. The fact that two composite elements are outside the grid and the displacement of the composite elements is mirror images of each other, is in a simple and advantageously achieves that the offset composite elements, when the paving stone is laid, are no longer located in the middle between two composite elements of an adjacent paving stone. The staggered composite elements are thus approximated to one of the composite elements of the adjacent paving stone. The mirror image displacement of the two offset composite elements ensures that an offset composite element ensures that the paving stone is delimited from an adjacent paving stone in a shift to the right, while the other staggered composite element limits a shift of the paving stone to the left. By the two staggered composite elements, two adjacent paving stones can be connected defined according to the idea of a key / lock principle, so that dimensional differences or installation errors over several stones can not add.

Compared to the generic font, the DE 103 30 928 B4 , The solution according to the invention has the advantage that more joint material, in particular sand, can be introduced. In the "key element", ie the wider composite element according to the DE 103 30 928 B4 It was not or only very limited possible to bring sand to the place where the wide composite element fills the space between two narrow composite elements of an adjacent paving stone. By contrast, the solution according to the invention makes it possible to use a key / lock principle without substantially impairing the introduction of sand into the intermediate spaces between two composite elements. In particular, each composite element of the paving stone can be sufficiently filled with sand from at least one side, or sand can adjoin the composite element accordingly.

The degree of tolerance of the key / lock system according to the invention can be determined by the amount by which the composite elements displaced in mirror image from one another are offset or arranged outside the grid dimension. In experiments, it has been found suitable to offset the composite elements in each case by 1.5 mm with a pitch of 25 mm. Ie. an offset of about 6% of the grid size or an offset between 2% and 20% of the locking measure has been found to be particularly suitable to allow a defined laying of the composite elements.

A punctual fixing two adjacent paving stones by the solution according to the invention is also supported by the fact that both paving stones can have the composite elements according to the invention offset.

It is advantageous if between the two offset composite elements at least two composite elements, preferably three composite elements are arranged, which are positioned within the grid dimension.

In experiments, this has been found to be particularly suitable with regard to a flexible use of the paving stone and the introduction of joint material.

It is furthermore advantageous if, on each flank of the stone, one of the staggered composite elements is arranged between a vertical stone edge and a composite element arranged in the grid. Furthermore, it has been found to be particularly suitable if one of the staggered composite elements of each flank adjacent to a vertical stone edge. When laying the paving stone can thus position particularly favorable.

It is preferably provided that exactly one staggered composite element adjoins each vertical stone edge. Such a design allows flexible use of the stones, without the publisher must pay attention to how the stone must be positioned. It can be provided, for example, that either always left or always right of the stone edge a staggered composite element is formed.

According to the invention, it can further be provided that the staggered composite elements are formed extended in a direction perpendicular to the stone flank with respect to the composite elements arranged in the grid.

The staggered composite elements thus fulfill not only their key / lock function but also the function of spacers. The staggered composite elements thus ensure that contact two adjacent paving stones only on the offset composite elements and thus a minimum joint width is guaranteed, especially between the normal, d. H. the arranged in grid composite elements and an opposite stone flank.

In principle, it is also possible according to the invention to design one or more of the composite elements arranged in the grid in a direction perpendicular to the flank of the stone. The functionality of the key / lock function does not have to be combined with the "distance function". It is also conceivable to extend one or more of the staggered composite elements and one or more of the arranged in grid composite elements in a direction perpendicular to the stone flank.

It is advantageous if, in the case of a paving stone with a square base area, the composite elements are respectively arranged identically on the four stone flanks. Ie. all four stone flanks have the same number of composite elements arranged in an identical position. The paving stone can thus be used without the publisher having to worry about its orientation.

It is advantageous if the composite elements extend over only part of the height of the stone. This makes it possible that a particularly large amount of joint material can be introduced between two paving stones, especially in the area of the composite elements.

Preferably, it is provided that the composite elements extend from the underside of the paving stone upwards, but end before reaching the top of the stone, preferably 20 mm +/- 10 mm before reaching the stone top. Another advantage is that the composite elements thus in the installed state, especially when joint material is introduced between the paving stones are not recognizable.

It is preferable if the composite elements are arranged only in the lower part of the stone flanks, in order to enable a continuous filling with grout material in the upper region of the stone flanks. When viewed from the top of the laid pavement, the viewer therefore receives the impression of a uniform continuous joint.

The composite elements need not necessarily begin from the underside of the stone, but rather the composite elements may also be spaced from the underside of the paving stone and may be interrupted.

It is advantageous if the thickness of the composite elements extending perpendicularly to the flank of the stone tapers in the direction of the top of the stone. Preferably, the composite elements end before reaching the stone top.

According to the invention, it can further be provided that individual composite elements arranged in the grid spacing are dispensed with, so that the distance between two adjacent composite elements arranged in the grid increases by an integral multiple of the grid dimension. In principle, however, a uniform distribution of the composite elements along the stone flank is to be preferred. However, in a simple embodiment, individual composite elements arranged in the grid can also be dispensed with.

For special applications of the paving stone, it may be advantageous if in the middle of a stone flank accounts for one or two arranged in grid composite elements. In principle, one or two arranged in grid composite elements, which are located between the two staggered composite elements omitted.

It is advantageous if no more than one or two arranged in grid composite elements per stone edge accounts.

In experiments, it has been found that the grid is a grid of 10 - 50 mm, d. H. a distance of 10 - 50 mm between the centers of two composite elements, particularly suitable. In particular, a grid dimension of 25 mm +/- 5 mm is suitable.

According to the invention, it may be provided that the thickness of the strip extending perpendicularly to the stone flank is offset Composite elements 3 - 6 mm, preferably 4.5 mm +/- 0.5 mm. Furthermore, it may be advantageous if the thickness of the composite elements arranged in the grid, perpendicular to the stone flank, is 2 to 5 mm, preferably 3.5 mm to 0.5 mm.

The strength stated with respect to the staggered composite elements refers to the fact that the staggered composite elements also fulfill the distance function. Insofar as this is not the case, the staggered composite elements can have the same thickness as the grid elements arranged in the grid. Only the composite elements which are to ensure the distance function are produced with an oversize.

It is advantageous if the composite elements that take over the distance function, at least at points about 1 mm +/- 0.5 mm further protrude than the composite elements without distance function.

According to the invention it can be provided that the composite elements, which are to ensure the distance function, have a greater width than the composite elements that do not fulfill a distance function.

Due to the greater width of the composite elements with distance function results at the same angle (course in the direction of the projecting tip of the composite element) that the composite elements with distance function on the composite elements survive without distance function. Alternatively, it can also be provided that the composite elements have the same width, but the composite elements with the distance function run at a more acute angle perpendicular to the stone flank. It is also possible, the To provide composite elements with the same width and the same angle. In this case, it can be achieved by a different rounding at the top of the composite elements, that the composite elements with distance function protrude further. These variants can also be combined with each other as desired.

The inventive solution according to claim 16 differs from the inventive solution according to claim 1, characterized in that each flank instead of two composite elements each having only one composite element which is offset within its position between two composite elements or a vertical stone edge and a composite element such that the offset composite element is arranged outside the grid. According to the invention, it is further provided that each vertical stone edge is assigned exactly one offset element arranged offset. The staggered composite elements are positioned on their stone flanks so that all composite elements have the same distance to the associated stone edge of the respective stone flank.

The fact that each offset composite element is arranged at the same distance from a stone edge and each stone edge is associated with exactly one staggered composite element, a specific arrangement of staggered composite elements is achieved, which makes it possible to lay the paving stones in a simple manner in the composite. By the solution according to the invention, for example, be provided that at each stone edge left or right of the stone edge a staggered composite element is located and regardless of which stone edge is assumed, the distance to the staggered composite element is the same.

In contrast to the solution according to the invention according to claim 1, the inventive solution according to claim 16 has the disadvantage that no exact key / lock positioning takes place by the staggered composite elements. It is only possible to apply the staggered composite element to an edge of a composite element of an adjacent paving stone. Under investing is to be understood that when laying the paving stones paving stones each defined can be placed together and the paving stones are thus positioned. However, the paving stones can be moved so that the staggered composite element from the edge of the composite element, on which this rests removed. Nevertheless, it has been found in experiments that already the possibility of a defined application when laying the paving stones is helpful and thus installation errors are avoided.

The embodiments described with regard to the solution according to the invention according to claim 1 can be realized analogously also in the solution according to the invention according to claim 16 and vice versa.

Advantageous embodiments and modifications of the invention will become apparent from the dependent claims. An exemplary embodiment of the invention is shown in principle below with reference to the drawing.

Paving stones may be formed of any suitable material, such as concrete, clinker, baked clay, or other materials useful for paving stone surfaces.

The paving stone 1 shown in the embodiment consists of a concrete body and has perpendicular to the laying plane aligned stone flanks 2. Composite elements (A, B, C, D) which correspond to composite elements of a stone flank 2 of an adjacent paving stone 1 are formed on the stone flanks 2. Each flank 2 in the exemplary embodiment has two configurations of composite elements (A and B) and (C and D), which differ at least in that the composite elements C and D of a configuration compared to the composite elements A and B of the other embodiment in one direction perpendicular to the stone flank 2 are extended. For the purposes of the invention, the embodiments of the composite elements differ at least or at least by their extent in a direction perpendicular to the stone flank 2. D. h. Composite elements are considered as belonging to another embodiment only if their maximum embankments in a direction perpendicular to the stone flank 2, d. H. their strengths differ. If the maximum extent (perpendicular to the stone flank 2) of two paving stones is the same, then the composite elements of the same configuration are assigned, even if they otherwise, for. B. in the course, the width, etc., differ significantly.

In the exemplary embodiment, the composite elements C and D are extended in a direction perpendicular to the stone flank 2 (see in particular FIGS. 1, 3 . 4 . 5 and 7 ). The composite elements A and B have a lower perpendicular to the stone flank 2 extending thickness.

In the exemplary embodiment it is provided that the composite elements C and D have a perpendicular to the stone edge 2 extending thickness of 4.5 mm. This is in Fig. 3 denoted by the reference numeral x. Furthermore, it is provided in the exemplary embodiment that the composite elements C and D have a course, as in Fig. 3 is shown in cross section. Ie. the composite elements C and D extend from a stone underside 3 in the direction of a stone top 4, but terminate before reaching the stone top 4. The composite elements C and D taper towards the stone top 4, as in Fig. 3 is shown.

In the exemplary embodiment it is provided that the composite elements A and B have a perpendicular to the stone edge 2 extending thickness of 3.5 mm. This is in Fig. 2 represented by the reference symbol y. The composite elements A and B also extend from the underside of the stone 3 in the direction of the stone top 4, without reaching the stone top 4. The composite elements A and B are tapered in the direction of the stone top 4. It is envisaged that the composite elements B taper in the manner as in Fig. 2 is shown. The composite elements A have a course, as in Fig. 3 is shown with respect to the composite elements C and D, but without having their strength.

As it turned out Fig. 1 results, the formed on the stone flanks 2 composite elements are each arranged in a grid, so that the composite elements each have an even horizontal distance to adjacent composite elements of the same stone flank 2. The grid dimension is in the exemplary embodiment 25 mm, ie the distance between a composite element A and a composite element B or between a composite element B and a composite element B is in the embodiment 25 mm in each case calculated from the center of the composite element A, B to the center of the adjacent composite element A, B. At each stone flank 2 are each two composite elements C, D within their position between two composite elements A, B or a composite element A, B and a vertical stone edge 5 mirror images of each other offset so that the two composite elements C, D are arranged outside the grid. Between the staggered composite elements are in the exemplary embodiment, three composite elements A, B, which are arranged in the grid. In the embodiment according to Fig. 1 is provided that the staggered composite elements C, D are offset by 1.5 mm to the grid. The composite elements C, D are each offset in the direction of the adjacent stone edge 5 by 1.5 mm to the outside. The composite elements D thus effect a shift lock to the left in the installed state of the paving stone 1, while the composite elements C cause a shift lock to the right. The in Fig. 1 shown paving stone 1 has uniformly long side edges 1, each having a length of 195 mm (with the reference numeral c in Fig. 1 designated).

The width of the composite elements C and D in the embodiment according to Fig. 1 13 1 mm (reference a). The width of the composite elements A and B is in the embodiment according to Fig. 1 chosen with 11.1 mm (reference numeral b in Fig. 1 ). The values are +/- 10%.

As it turned out Fig. 1 furthermore, exactly one staggered composite element D is arranged adjacent each stone edge 5. Ie. On each stone flank 2, one of the staggered composite elements D is arranged between the vertical stone edge 5 and a composite element A arranged in the grid.

As it turned out Fig. 1 results, the paving stone 1 is designed with a square base, wherein the composite elements A, B, C, D are respectively arranged identically to the four stone sides 2.

Fig. 4 shows one too Fig. 1 alternative embodiment of a paving stone 1. This differs from Fig. 1 only in that a composite element A, B is omitted in each case on two opposing stone flanks 2. The distance between two adjacent, arranged in grid composite elements A, B is thereby increased by an integer multiple of the grid. In the exemplary embodiment, a composite element B is omitted in each case at the two stone flanks 2 in the region of the middle of the flank 2 of the stone. Ie. the distance between two composite elements A and B has increased by a multiple, between these is in the embodiment, even a staggered composite element C.

Fig. 5 differs from Fig. 4 in that the in Fig. 4 shown paving stone 1 is divided into two halves. The subdivision is done so that the paving stone 1 according to Fig. 4 is divided into two equal halves. As a result, only three stone sides 2 of the paving stone 1 composite elements A, B, C, D on. This too should be encompassed by the solution according to the invention.

Such a stone is suitable for special applications.

Fig. 6 shows a possible arrangement of paving stones 1 according to the invention in a stone package, ie in a state in which they can be delivered to a construction site. Shown here are also two paving stones 1 according to Fig. 5 ,

Fig. 7 shows in detail two staggered composite elements C, D, which adjoin a stone edge 2 of an adjacent paving stone 1. In the in Fig. 7 illustrated embodiment, the staggered composite elements C, D are each mirror image offset to the outside by 2.5 mm (reference numeral 1). The original position (in pitch) is in Fig. 7 shown in dashed lines. As a result, the distance between the staggered composite members C and D and each composite A of an adjacent paving block 1 decreases to 2 mm while the distance to the composite member A, from which the composite member C is further spaced, increases to 7 mm. The shortened distance is in Fig. 7 represented by the reference character k, while the enlarged distance is represented by the reference numeral v. The extent to which the composite elements C, D are offset from the original position is in FIG Fig. 7 indicated by the reference numeral l. Reference symbol r denotes the regular distance (4.5 mm) of two composite elements arranged in the grid.

As it turned out Fig. 7 yields, by a suitable displacement of the composite elements C, D set the key / lock principle arbitrarily exactly.

Fig. 8b shows a possible Aneinanderetzen of two paving stones 1, each having two staggered composite elements C and D on each flank 2. For reasons of clarity, the staggered composite elements C and D are in Fig. 8b shown blackened. The non-staggered composite elements, ie the composite elements A, B, which are located in the grid, are in Fig. 8b not shown blackened.

In Fig. 8b the staggered composite elements C and D are each shifted so that the composite elements C and D have moved away from each other. Alternatively, however, the composite elements C and D may also be offset from one another in a mirror-inverted manner so that the composite elements C and D are closer to one another. In both cases, there is a suitable key / lock principle. As further out Fig. 8 results, the staggered composite elements C and D turn meet the distance function, ie they are formed perpendicular to the flank 2 extended.

Fig. 8a basically shows an arrangement according to Fig. 8b However, only one composite element C or D is formed on each flank 2. This corresponds to the solution according to the invention according to claim 16. The composite element C or D arranged on a stone flank 2 is in each case associated with a vertical stone edge 5. The composite elements C and D each have, starting from the associated vertical stone edge 5 at an identical distance.

In the embodiment according to Fig. 8a the paving stone 1 has a square base. Furthermore, all the stone flanks 2 are identical with composite elements C, D and A, B provided. In principle, the staggered composite element C or D need not be arranged directly adjacent to a vertical stone edge 5. It is also conceivable that the staggered composite element C or D is positioned between two arranged in grid composite elements A, B. According to the invention, however, it is to be ensured according to claim 16 that the staggered composite elements C and D each have the same spacing relative to the associated vertical stone edge 5. This is true even if the paving stone 1 is not a square paving stone 1.

As it turned out Fig. 8a can be seen, serve the staggered composite elements C and D essentially means that the paving stone 1 can be applied to an adjacent paving stone 1 and its composite elements A, B defined. The in Fig. 8a upper paving stone 1 can no longer be moved to the left compared to the lower paving stone 1, as this is prevented by the staggered composite elements C and D. The upper paving stone 1, however, can be moved to the right. In the Fig. 8a Thus, the solution presented does not offer a "key / lock principle", as in Fig. 8b is shown, but allows only a defined creation.

The Fig. 9 shows six laid to a pavement stones, which are each provided at their side edges 2 with two composite elements C, D. As is clear from the Fig. 9 results, the solution according to the invention not only allows optimal laying of stones of the same size, but it can stones of different sizes are combined. Furthermore, it is possible to lay the paving stones 1 according to the invention in the cross dressing or as shown in the runners association. At the in Fig. 9 blackened dargstellten composite elements are again the staggered composite elements C, D. The non-blackened composite elements A, B are arranged in the grid composite elements A, B. The composite elements C, D according to Fig. 9 again fulfill a distance function.

With the solution according to the invention, paving stones 1 of any desired size, for example also five- or hexagonal stones, can be produced.

    the grid spacing measures 10 to 50 mm, preferably 25 mm +/- 5 mm.
13. Paving stone according to one of Claims 1 to 12,
    characterised in that
    the thickness, extending perpendicular to the stone flank (2), of the offset interlocking elements (C,D) measures 3 to 6 mm, preferably 4.5 mm +/- 0.5 mm.
14. Paving stone according to one of Claims 1 to 13,
    characterised in that
    the thickness, extending perpendicular to the stone flank (2), of the interlocking elements (A,B) arranged in the grid spacing measures 2 to 5 mm, preferably 3.5 mm +/- 0.5 mm.
15. Paving stone according to one of Claims 1 to 14,
    characterised in that
    the offset interlocking elements (C,D) are offset by 1 to 10 mm, preferably 1.5 mm, in relation to the grid spacing.
16. Paving stone having stone flanks oriented preferably perpendicular to the laying plane, wherein on the stone flanks are formed interlocking elements which correspond to interlocking elements of a stone flank of an adjacent paving stone, wherein at least two configurations of interlocking elements are provided, which configurations differ at least in that the interlocking elements of one configuration are elongated in a direction perpendicular to the stone flank in relation to the interlocking elements of the other configuration, wherein on each stone flank (2) of each configuration at least one interlocking element (A,B or C,D) is formed, and the interlocking elements (A,B,C,D) formed on the stone flanks (2) are respectively arranged in a grid spacing, so that the interlocking elements (A,B,C,D) respectively have a uniform horizontal distance to adjacent interlocking elements (A,B,C,D) of the same stone flank (2),
    characterised in that
    each stone flank (2) respectively has an interlocking element (C,D), which, within its position between two interlocking elements (A,B) or a vertical stone edge (5) and an interlocking element (C,D), is offset in such a way that the offset interlocking element (C,D) is arranged outside of the grid spacing, wherein to each vertical stone edge (5) is assigned precisely one offset interlocking element (C,D) and the offset interlocking elements (C,D) are positioned on their respective stone flanks (2) such that all interlocking elements (C,D) have the same distance to the associated stone edge (5).
