Description

The present invention relates to a paving stone according to the preamble of claim 1 and a composite of a plurality of such paving stones and a method for producing a laying package of several paving stones.

Paving stones with an H-shaped basic shape have long been known in practice. They usually have a walkable or passable top, a bottom facing the ground and a substantially rectilinearly extending between the top and the bottom edge. The basic shape of the upper side or the underside consists of two substantially rectangular sections, which are spaced apart and extend substantially parallel to one another in a first direction, and a further substantially rectangular section, which connects the two parallel sections substantially perpendicular to each other and in a second direction, which is substantially perpendicular to the first direction, is aligned.

Such H-shaped paving stones are for example from the DE 296 03 148 U1 , of the DE 197 33 741 C2 or the DE 201 13 580 U1 known. The paving stones described therein each have a basic shape in which the inner flanks of the two parallel sections, which face the connecting section, enclose an angle of more than 90 degrees with respect to this, so that the paving stones can be pushed into one another during laying to the desired composite. In addition, at the edge of the paving stone in each case a plurality of projections are formed substantially perpendicular to the top, which serve exclusively as spacers for the joint formation and come into abutment with the projections of the adjacent paving stones. These spacers of conventional paving stones achieve no composite effect, but serve only to comply with a desired Joint width and the prevention of edge damage on the stone top during handling.

When manufacturing these conventional paving stones created, due to the manufacturing forms, a distance between the individual paving stones. For palletizing then the paving stones are pushed together in two mutually orthogonal directions on the production board, so that a loose bond is formed. When manually or mechanically laying the paving stones this loose bond is maintained. The problem here is that when exposed to appropriate forces, for example when driving on vehicles, this composite of paving stones can also be easily dissolved again. To counteract this, it is known to hold together the installed composite of paving stones with the aid of suitable curb elements.

Depending on the basic shape of the paving stone, it is possible to achieve a mutual toothing of the adjacent paving stones by molding the projections or spacers in staggered arrangement. Such paving stones are for example from the DE 103 30 928 A1 known. However, a composite laid with such paving stones can nevertheless be pushed apart in at least one direction if it is not held together by curb elements or the like.

Paving stones for achieving a stable bond in both directions are, for example, in DE 31 42 745 A1 . DE 295 08 723 U1 and DE 295 18 770 U1 disclosed. These conventional paving stones are formed with dovetail-shaped projections and teeth, so that they can be put together in the manner of a puzzle. This is possible either with or without spacing between the adjacent paving stones, ie as a composite with or without joints. However, a transfer of this system to H-shaped paving stones would lead to a complicated stone form and thus to correspondingly complicated and complex forms of production.

The DE 295 01 168 U1 describes a self-locking composite plaster of joinable paving stones in double T-shape. Compared to the aforementioned H-shaped paving stones indicate the double-T-shaped paving stones the outer sections additionally inwardly directed flanges, with which adjacent paving stones can be hooked into each other.

It is an object of the present invention to provide an H-shaped paving stone which can be laid in a stable composite.

According to the present invention, this object is achieved by a paving stone with the features of claim 1. Advantageous developments and refinements are specified in the dependent claims.

The paving stone for forming a composite of a plurality of such paving stones has a walkable or passable top, an upper side facing away from the top and a running between the top and the bottom edge. The upper side has a substantially H-shaped basic shape consisting of a first and a second substantially rectangular portion, which are spaced apart and substantially parallel to each other and aligned in a first direction, and a third substantially rectangular portion which connecting the first and second sections substantially perpendicularly and aligned in a second direction substantially perpendicular to the first direction, wherein inner flanks of the first and second sections facing the third section are aligned therewith one Include angle. The paving stone is characterized in that in the region of each inner flank of the first and second sections at least one projection is provided, which is integrally formed on the edge of the paving stone substantially perpendicular to the top, wherein a depth of the projections parallel to the top of the paving stone more than one Half of a joint width between two adjacent paving stones in the composite amounts. Further, widths of the first and second portions at the edge remote from the third portion in the second direction, the depth and positioning of the projections, and the angle between the inner edges of the first and second portions and the third portion are selected such that The first direction adjacent paving stones can not be pushed together in the first direction to the composite.

In the paving block of the invention, widths of the first and second portions in the second direction, the depth and positioning of the protrusions, and the angle between the inner flanks of the first and second portions and the third portion are selected so as to be adjacent in the first direction Paving stones can not be pushed together in the first direction to the composite. By this measure, the paving stones are interlocked with each other both in the first direction (through the protrusions) and in the second direction (through the first and second sections themselves) and can not be pushed apart in either the first or the second direction. In this way, even without special curb elements for limiting a stable composite of paving stones can be achieved. In addition, the H-paving stones maintain a relatively simple shape.

The "paving stones" are moldings made of concrete, clinker, plastic or any other material. They can be used for attaching, for example, walkways, driveways, squares, parking lots and the like. The dimensions (width, length, height) of the paving stones are basically neither up nor down limited.

The paving stones can be formed both as solid moldings as well as partially hollow moldings. In addition, the top of the paving stones can be configured either fully closed or partially open. Permeable paving stones are also known in the professional world as so-called "grass stones".

The top and bottom of the paving stone are generally substantially parallel to one another and the edge is generally substantially straight between the top and bottom without the invention being limited to these two aspects. Furthermore, the basic shape of the underside usually agrees with the basic shape of the top, although the invention should not be limited thereto. In addition, the top and bottom do not necessarily have to be substantially planar, they may also have bulges, structures, profiles, etc. In particular, it is conceivable to use the underside of the Paving stone with groove-like profiles for the purpose of drainage or with profiles for better anchoring the paving stones on the ground form. The edges of the paving stone can either be sharp-edged, rounded or broken.

The "rectangular" shape of the first, the second and the third portion of the H-shaped basic shape of the top of the paving stone refers to the basic shape of these sections. These sections may, for example, both rectilinear, sectionally rectilinear, curved and / or curved sections have edges running. Also, the respective opposite edges of the "rectangles" do not necessarily have to be exactly parallel to one another. Thus, it is also possible in particular by an angular adjustment of at least one extending in the second direction outer edge of the connecting third portion and / or an angular employment of extending in the first direction outer edge of the first and / or the second portion of the paving stones a certain wedge shape lend and thus provide a so-called set of curves for laying paving stone composites with curves or radii.

Furthermore, the H-shaped paving stones are generally symmetrical. That the first and second portions are formed substantially identically to each other and the third portion is positioned substantially centrally with respect to the first and second portions in the first direction. In the context of the present invention, however, deviations from this exactly symmetrical basic H-shape are also to be possible. For example, the angles of the inner flanks of the first and the second portion relative to the third portion may also be different from each other.

To be distinguished from the "H-shaped paving stones" for the purposes of this invention are paving stones with basic shapes that have other elements in addition to the pure H-shape. Such additional elements are, for example, on the first and second portions inwardly projecting flanges for forming a double-T-shape in the sense of, for example DE 295 01 168 U1 or dovetail-shaped projections for forming puzzle-like paving stones in the sense of, for example, the DE 31 42 745 A1 ,

The "inner flanks" are to be understood as meaning special sections of the edge of the paving stone, which-with respect to the H-shaped basic shape-are provided on the first and second sections and face the third section connecting them.

At these inner flanks, "at least one projection" is provided in each case, which depending on the size of the paving stone and the desired accuracy of the mutual toothing of paving stones adjacent to each other can be exactly one, two, three or more projections on an inner flank , In this case, the projections are positioned on the inner flanks in such a way that the projections of two paving stones adjacent to one another are offset relative to one another, so that they can interlock with one another. The more accurate the accuracy of this toothing should be, the closer the staggered projections of the adjacent projections are arranged to each other.

The "integrally formed on the edge projections" are preferably made in one piece with the molding of the paving stone, but can optionally be firmly connected to this. The "projections" may in principle have any cross section, but they preferably have a rectangular or square cross section with sharp or rounded edges or a semi-circular or semi-elliptical cross section.

In addition, the projections in the height direction of the paving stone, ie in the direction of connection of the edge between the top and the bottom of the paving stone, generally extend a predetermined amount, which may correspond to the total height of the paving stone, but may also be smaller. Preferably, the projections extend at least over half the height of the paving stone. In this case, the projections do not necessarily complete with the top or bottom of the paving stone. In a preferred embodiment, the protrusions extend from the underside of the plaster over at least half the height of the paving stone towards the top. Furthermore, the upper and / or the lower end of a projection in the height direction of the paving stone optionally be parallel to the top or bottom of the paving stone or beveled.

In one embodiment of the invention, the angle between the inner flanks of the first and second sections and the third section is substantially 90 degrees, i. the inner flanks of the first and second sections are oriented substantially perpendicular to the connecting third section.

In another embodiment of the invention, the angle between the inner flanks of the first and second sections on the one hand and the third section on the other hand in the range of about 90 degrees to about 150 degrees, preferably from about 105 degrees to about 135 degrees. This angular orientation of the inner flanks relative to the third section need not necessarily extend over the entire length of the inner flanks.

Further, the paving stone may optionally only on the inner flanks of the first and second sections, on the inner flanks of the first and second sections and on the first-direction edge portions of the first and second sections or on the inner flanks of the first and of the second portion, at the edge portions extending in the first direction of the first and the second portion and at the extending in the second direction edge portions of the first, second and third portions with projections.

In a further embodiment of the invention, in the paving stones described above, the depth of the protrusions may range from about 60% to about 90%, preferably from about 65% to about 85%, of the joint width between two adjacent paving stones in the composite.

In an advantageous embodiment of the invention, in the paving stones described above, the projections may be spaced from the top of the paving stones. In this way, the projections between the adjacent paving stones in the composite with filled joints invisible and the composite shows only the H-shape of the paving stones.

In a further advantageous embodiment of the invention may be provided at the above-described paving stones in the region of the first, second and / or third portion at least one opening extending from the top to the bottom of the paving stone. Paving stones with such openings can be used for example as grass stones. Further advantages of such paving stones can be: lower weight, less material used for production, design elements of the top, better infiltration of rainwater.

The paving stones according to the invention described above can be advantageously laid to a stable composite by being pushed together in the second direction and lifted into each other in the first direction. In this case, the paving stones according to the invention are laid in substantially the same orientation to each other.

This laying of paving stones can be done either by machine or by hand. In such a composite of paving stones can be dispensed with special curb elements to limit advantageously. Of course, if desired, such curb elements can still be used as an additional mechanical or optical measure.

Furthermore, the features and configurations of the paving block according to the invention described above can also be combined with each other as desired. In particular, the inner flanks of the first and second sections can also have a plurality of sections with different angles to the third section. Further, not all inner flanks of the first and second sections need to enclose the same angle with the connecting third section of the paving stone.

Finally, from the paving stones of the invention described above also advantageously a laying package can be made of several paving stones. The inventive method for producing a laying package of several paving stones includes the steps of making several inventive paving stones, pushing together several of these paving stones in the second direction to a row, and the nesting of at least two of the thus assembled rows of paving stones in the first direction.

Due to the inventive construction of the paving stones and the nesting of the paving stones in the first direction (in contrast to the conventional mere pushing together) a stable bond of the paving stones is already achieved in the provision of the laying package. Due to the improved stability of such a laying package, these laying packages can then be processed more easily, i. in particular stored, transported and laid on site to form a composite of a variety of paving stones.

A "laying package" is a summary of several paving stones after their production, which can be laid by means of appropriate laying machines. The use of laying packages has long been known and leads to a reduction in installation costs and a shortening of the laying time. When laying the pavers on site then several such laying package are laid together to form a larger composite.

According to the invention, in each case several paving stones are lifted together into several other paving stones. In this way, the time to assemble the laying package can be shortened.

A laying package of the H-shaped paving stones according to the invention consists for example of four rows of four paving stones, without the invention being limited to these numbers.

In a preferred embodiment of the invention, the nesting of the paving stones to form the laying package is performed by machine.

FIG. 1 shows first an H-paving stone 10 in its basic design, from which in a conventional manner, a composite or laying package of nested paving stones can be made.

The paving stone 10 has a walkable or passable trained top 12 and the top 12 facing away, i. in the installed state the underside facing the bottom 14. The top 12 and the bottom 14 are connected by a peripheral, substantially linearly extending therebetween edge 16 with each other.

A first embodiment of this H-shaped paving stone will now be described with reference to FIGS FIGS. 2 to 4 described in more detail. Here are some of the adjacent paving stones in dashed lines indicated.

The top 12 - and generally also the bottom 14 - has a substantially H-shaped basic shape, best seen in plan, as in FIG FIG. 2 illustrated. This basic H-shape is composed of a first section 18a, a second section 18b and a third section 18c. The first and second sections 18a, 18b are substantially rectangular in shape, substantially parallel to each other, and substantially aligned in a first direction A. The third portion 18c connects the first and second portions 18a, 18b to each other, is also substantially rectangular in shape, is disposed substantially centrally with the first and second portions 18a, 18b in the first direction A, and is substantially in a second direction B. aligned. The first direction A and the second direction B are substantially perpendicular to each other.

The (four in total) edge portions of the first and second portions 18a, 18b facing the connecting third portion 18c, which are inner flanks 20, subtend a predetermined angle W with this third portion 18c, which is approximately 90 in this embodiment Degree is.

Further, along the periphery of the paving stone 10, a plurality of protrusions 22 are provided. These projections 22 are integrally formed on the edge 16 of the paving stone 10 and extend substantially perpendicular to the top 12, ie substantially parallel to the direction of connection between the top 12 and the bottom 14 or substantially in the height direction of the paving stone 10. In one embodiment, these projections 22 extend approximately from the bottom 14 of the paving stone 10th at least over half the height, preferably about 50-90 or even 95%, more preferably about 60-85% towards the top 14 of the paving stone 10.

A possible shape and distribution of the projections 22 at the edges 16 of the paving stone 10 is in Figure 1A can be seen, in which the height h of the paving stone 10 is located. As in Figure 1A shown, the projections 22 are each beveled at their the top 12 of the paving stone 10 facing ends, these ends may have different curves. Due to the spacing of the projections 22 from the top 12 of the paving stone 10, these are hidden by the joint filling and are no longer visible to the viewer in the finished composite.

FIG. 1B shows a variant of this paving stone 10 with two openings 13 in the region of the middle third portion 18c extending from the top 12 to the bottom 14 of the paving stone. Through these openings 13, the paving stone 10 can also be used as a lawn stone. In addition, it has a lighter weight and an improved infiltration of rainwater.

On or in the top 12 of the paving stone 10 also profilings 15 or the like may be provided, which may change, for example, the design of the paving stone 10 and thus the entire composite of paving stones.

As in the top view of FIG. 2 can be seen on the basis of the indicated adjacent paving stones, the depth d of the projections 22 parallel to the top 14 and perpendicular to the edge 16 of the paving stone 10 more than half of the joint width f between two adjacent paving stones 10. In this embodiment, this depth d of the projections 22nd in the range of about 60% to about 90%, preferably from about 65% to about 85% of the joint width f between two adjacent paving stones 10 in the composite.

Next is in FIG. 2 recognizable that at least one such projection 22 is provided on the inner flanks 20 of the first and second portions 18a, 18b of the paving stone 10, preferably at least two such projections 22 are provided.

As in Figures 1A and 1B shown, in this embodiment, two adjacent projections 22 in the region of the underside 14 of the paving stone 10 are connected to each other via a web. Then a projection 22 of the adjacent paving stone 10, which is positioned between the two projections 22, abuts against this web. In this way, a desired joint width f can be ensured.

In order to achieve a stable composite of the laid paving stones 10, the projections 22 are offset on the inner flanks 20 at two adjacent paving stones 10 to each other and at a close distance from each other. In this way, the projections 22 on the inner flanks 20 in the first direction A interlock. In the second direction B, the mutual toothing is achieved by the shape of the paving stones 10. In this case, the widths b of the first and second sections 18a, 18b in the second direction B and the depth d of the projections 22 on the inner flanks 20 and possibly on the first direction A extending edge portions of the first and second portions 18a, 18b be selected so that the projections 22 interlock at the inner edges 20 of two adjacent paving stones 10 in one another and thus prevent mutual displacement of these adjacent paving stones 10 in the first direction A.

The paving stones 10 can therefore not be pushed together in the first direction A to form a composite. Instead, the paving stones 10 must be lifted into one another in this first direction A and subsequently form a composite of paving stones 10 which can not be detached either in the first direction A or in the second direction B.

The formation of the association is in FIG. 3 illustrated. The paving stones 10 can either be spent loose to the site and laid there to composite or previously combined into so-called laying packages before they are laid on the construction site with suitable laying machines for the final composite.

In FIG. 3A First, some paving stones 10 are pushed together in the second direction B to a row. As in FIG. 3B the rows of paving stones 10 thus formed can be pushed together in the first direction A only until their corners or their projections 22 closest to the corners abut one another. Now these rows of paving stones 10 in the first direction A must be raised into each other, as in FIG. 3C shown to form the composite. In the FIGS. 3A to 3C shown operations can be done either manually and / or by machine. A laying package produced in this way comprises, for example, four rows each with four paving stones 10.

In this embodiment, furthermore, projections 22 are provided on the edge portions of the first and second portions 18a, 18b extending in the first direction A and also on the edge portions of the first, second and third portions 18a, 18b, 18c extending in the second direction B. intended. However, only the projections 22 on the inner flanks 20 of the first and second sections 18a, 18b are absolutely necessary for the inventive toothing of adjacent paving stones 10 for stable bonding. This is exemplary in FIG. 5 illustrated as a third embodiment.

FIG. 4 shows a section of a thus produced laying package or composite of paving 10. In the edge region of the laying package or curbs are used 11, which can be regarded as half, in the middle of the third portion 18c divided paving stones 10 of the invention. Such a curb 11 is also in again Fig. 4A individually illustrated.

With reference to FIG. 5 Now, a second embodiment of a paving stone according to the invention will be described in more detail. The same or similar components are again with the same reference numerals as in the above-described provided first embodiment. For the sake of simplicity, the projections 22 in the illustration of FIG. 5 been omitted.

The embodiment of FIG. 5 is different from the ones in the Figures 2 and 6 illustrated embodiments in that the angle W, the inner flanks 20 of the first and second portions 18a, 18b include with the connecting portion 18c, each selected greater than 90 degrees.

In the example of FIG. 5 this angle W is about 120 degrees. Generally, this angle W is in the range of about 90 degrees to about 150 degrees, preferably from about 105 degrees to about 135 degrees.

In this basic shape of the H-shaped paving stone, which essentially corresponds to that of the conventional H-paving stones, care must be taken that the depth d of the projections 22 on the inner flanks 20 is sufficiently large, so that the mutual interlocking between the adjoining paving stones 10 guaranteed and a nesting and pushing apart adjacent paving stones in the first direction A is prevented.

The remaining features and the way of laying this paving stone 10 correspond to those of the first embodiment of FIG. 2 , Likewise, the variant of FIG. 6 , in which the projections 22 are integrally formed only on the inner flanks 20 of the first and second sections 18a, 18b on the edge 16, on the embodiments of FIG. 2 and also from FIG. 5 transferable.

Referring to FIG. 7 For comparison, a conventional paving stone is described in more detail, as he, for example, from the DE 94 08 693 U1 is known. The same or similar components are again identified by the same reference numerals as in the embodiments described above.

At the paving stone of FIG. 7 is the angle W included by the inner flanks 20 of the first and second sections 18a, 18b with the third section 18c, each chosen smaller than 90 degrees. In the example of FIG. 7 this angle W is exemplarily about 60 degrees.

In this embodiment, the mutual interlocking between adjacent paving stones 10 is achieved solely by their basic shape. The provision of projections 22 on the inner flanks 20 of the first and second sections 18a, 18b is not absolutely necessary for this purpose.

In the case of DE 94 08 693 U1 is the in FIG. 7 illustrated paving stone also be provided with integrally formed on the edge 16 projections 22. These projections 22 can optionally on the inner flanks 20 of the first and second portions 18a, 18b, on the edge portions of the first and second portions 18a, 18b extending in the first direction A and / or on the edge portions extending in the second direction B. of the first, second and third sections 18a, 18b, 18c.

In the recess formed between the opposite inner flanks 20 of the first and the second portion 18a, 18b of the paving stone 10 then, as in the above embodiments, respectively the first and second portions of two adjacent paving stones are used. For this purpose, the width c of the recess between the first and second portions 18a, 18b is greater than the sum of the widths b of the first portion 18a and the second portion 18b.

As in FIG. 7 is indicated, while the width c of the recess at the boundary to the third portion 18 c and the widths b of the first and second portions 18 a, 18 b can be measured at the outer edges to obtain the largest dimensions. Alternatively, in each case the smallest dimensions can be used, ie the width c of the recess at the outer edge of the paving stone 10 and the widths b of the first and second sections 18a, 18b at the level of the flank of the third section 18c. As a further alternative, a determination of all widths b and c midway between the flank of the third section 18c and the outer edges of the first and second sections 18a, 18b is conceivable.

While in the embodiments described above FIGS. 1 to 6 In each case the flanks of the connecting third section 18c of the paving stone were aligned substantially parallel to one another and substantially parallel to the second direction B, it is also possible to make at least one of the two flanks of the third section 18c at an angle to the second direction B. This angle is for example in the range of about 2 to 5 degrees.

By this construction results in a certain wedge shape of the paving stone 10 in the second direction. In this way, a so-called set of paving stones 10 can be produced, with which a composite with curves or radii can be laid. Such a set of curves is already known in principle to the person skilled in the art (see, for example, a curve set for paving stones with the designation UNNI-2N of UNI-International Bausysteme GmbH & Co. KG, Bremen), so that it need not be explained in more detail here.
