Abstract

The invention relates to a system of shaped blocks, comprising full blocks with an essentially rectangular base and half-blocks, which are essentially formed by halving the full block in the transversal central plane, for laying in the longitudinal bond. Each section (2a, 2b, 3a, 3b) of the longitudinal sides of a full block (1a), which are separated by a transversal central plane (7), has at least two studs (12, 13; 14, 15; 43, 44; 45, 46), the stud (12; 15; 43; 46) that is closer to one transversal side (4, 5) of the shaped block (1) forming an interlocking pair (48) with a stud (13; 14; 44; 45) of a corresponding block that is further from a transversal side (4, 5), said pair being positioned at least a stud-width away from an interlocking pair (49) formed by the stud (13; 14; 44; 45) that is further away from the transversal side (4, 5) and the stud (12; 15; 43; 46) of the corresponding block that is closer to the transversal side.

Description

"Shaped stone"

The invention relates to a shaped block system according to the preamble of patent claim 1.

Such a shaped block system is known from DE GM 87 0 821. A disadvantage of this shaped stone system is that the stones do not hold each other in the bandage and even drift out of the bandage on the wheels, since the cams only serve as distance cams. Furthermore, it is not safe to walk on such coverings, at least with thin heels, since wide gaps are formed between the individual stones.

In addition, shaped stone systems are known from the prior art which have no cams, this means that the rainwater can only seep away between the butt joints in small quantities and there are no possibilities for positively influencing the seepage amount.

The invention has for its object to develop a shaped stone that ensures optimal cohesion of the stone dressing and good water drainage while being easy to walk on.

This object is achieved in connection with the preamble of claim 1 according to the invention in that each section of the longitudinal sides separated by a transverse central plane of a solid brick has at least two cams, the cam closer to a transverse side of the shaped block forming a pair of teeth with a cam of a counter brick further away from a transverse side, which is spaced apart by at least one cam width from a pair of teeth which is the cam further away from the transverse side with the cam closer to the transverse side of the counter stone. The formation of tooth pairs, which consist of only two cams, on the one hand ensures that the shaped block is in engagement and contact with the respective counter block at several points along its longitudinal side, so that the molded block and the counter block are aligned parallel to one another and are non-displaceable . On the other hand, it is ensured that along the long side of the molded block between the pairs of teeth there is still sufficient side surface for the formation of drainage shafts or that the cams can be dimensioned in a sufficient width and that a small stone spacing is sufficient to form a sufficiently dimensioned drainage shaft . Another advantage is that this interlocking allows optimal grouting with sand. In addition, production with a simple tool is possible, since the undercuts of the shaped stone are evenly distributed on its side surface and thus there are no accumulations of moving parts in the molding tool, which require complicated, susceptible mechanics.

According to a preferred embodiment, the shaped stone is also present as a half stone, which results from halving the solid stone in the transverse central plane, minus half the depth of a cam provided there. This has the advantage that the milling program for the CNC milling machine can be adopted almost completely from the program for the solid stone when producing the shape for the half stones. Furthermore, it is advantageous to arrange the cam closer to a transverse side or long side of the shaped block at least half a cam width away from the adjacent long side or transverse side. This ensures that the forces that this cam experiences as a distance and / or toothing means through the counter block or transmits to the counter block do not act on a sensitive corner area of the shaped block, so that breaking off or cracking of a corner area is unlikely.

According to a particularly advantageous embodiment of the subject of the invention, water drainage ducts are formed between the pairs of teeth. This ensures that the shaped stone has at least two water drainage shafts on its long sides and that the water on the stone surface only has to cover short distances to the next drainage shaft.

A particularly advantageous embodiment of the subject matter of the invention exists if the shaped block has channels running on its underside in a mirror-symmetrical manner to the transverse center plane. This measure makes it possible to connect the individual drain shafts of the shaped block to one another and to prevent the channel from running in the transverse central plane of the shaped block. The resistance of the molded block to bending stress is thus greatly increased, since weakening of the molded block is avoided precisely at the point which is most critical for bending stress.

A particularly advantageous embodiment of the subject matter of the invention is present when the channels connect those water drainage shafts which lie opposite one another with respect to the line of intersection of the longitudinal center plane with the transverse center plane, the channels intersecting. Through this As a measure, a channel system is created that not only allows the water to flow away in the longitudinal direction, but also allows the water to move in all directions under the stone structure. It is therefore possible for the water to drain off in all directions from places where it cannot seep away, and the risk of puddling due to water build-up on the stone surface is therefore lower.

In order to enlarge the area of the canal or the area over which the water seeps away, it is further advantageous that the water drainage chutes each have a first channel which connects them to the water drainage chute opposite the longitudinal central plane, and a second channel which connects them connects with the water drainage duct opposite with respect to the line of intersection of the longitudinal median plane with the transverse median plane.

A further advantageous embodiment of the subject matter of the invention exists when each section of the transverse side has at least two cams, the cam closer to the longitudinal center plane forming a pair of teeth with a cam of a counter block that is further away from the longitudinal center plane and that is spaced apart from the pair of teeth that is closer to the cam forms with the cam of the counter block closer to the longitudinal center plane, and the cam close to the longitudinal center plane together with that of the cam of the counter block close to the longitudinal center plane forms a third pair of teeth. Through this embodiment, three pairs of teeth are formed in a confined space, which prevent displacement of the molded block against the counter block along the transverse side in two directions.

Further details of the invention are shown in the drawing described using schematically illustrated embodiments.

In Fig. 1, a shaped block 1, which is designed as a solid stone la, is shown in a perspective view. The shaped stone 1 has long sides 2, 3 and transverse sides 4, 5. The Vollstein la is divided by a longitudinal central plane 6 and a transverse central plane 7. The longitudinal center plane 6 and the transverse center plane 7 intersect in a line of intersection 8. The transverse center plane 7 divides the longitudinal sides 2, 3 into half sides 2a, 2b and 3a, 3b. On the long sides 2, 3 and the transverse sides 4, 5, the molded block 1 has spacing or toothing means 9. These are visible in Fig. 1 as cams 10 to 15. The shaped block 1 is essentially delimited by a contour 22, which is formed by an upper edge 23, side edges 24 and a lower edge 25. According to an alternative embodiment, not shown, the edges 23, 24, 25 are optionally provided with chamfers. As a result, an attractive appearance and an insensitivity of the edges 23, 24, 25 to small damage is achieved. The spacing or toothing means 9 have a cam width b. Each spacing or toothing means 9 is at a distance a from the side edges 24 which corresponds to at least half the cam width b.

FIG. 2 shows a shaped block 1 designed as a half stone 1b. The half stone 1b also has spacing or toothing means 9, specifically the cams 10 to 13 can be seen. Like all spacing or toothing means 9, these have contact surfaces 26, thrust surfaces 27 and cover surfaces 28, the cover surfaces 28 rising from the contact surfaces 26 to the long sides 2, 3 or to the transverse sides 4, 5. The push surfaces 27 also form an oblique transition from the contact surfaces 26 to the long sides 2, 3 or transverse sides 4, 5. The molded block 1 has an upper side 29 and a lower side 30.

FIG. 3 shows a top view of shaped stones 1 laid in the association 40. Specifically, the association consists of a half stone 40a, a solid stone 40b and another part visible full stone 40c. The cams 41 to 46 hidden in FIG. 1 can be seen in the top view of the solid brick 40b. The cams 41 to 44, which are hidden in FIG. 2, can be seen in the top view of the half-stone 40a. Furthermore, FIG. 3 shows that the shaped stones 1 are arranged at equal distances d from one another, ie the full stones 40b, 40c and the half stones 40a lie opposite one another with their long sides 2, 3 and their transverse sides 3, 4 with the same spacing d. These distances correspond approximately to a depth t of the spacing or toothing means 9

47 are placed, whose raster width 47a in the x direction corresponds to half a full stone length L plus half a cam depth t. In the y direction, the grid 47 has a grid width 47b which corresponds to a shaped block width B plus two half cam depths t. The half stone 1b is produced from the solid stone la by halving the solid stone la in the transverse central plane 7, minus half the depth of a cam 10, 11 or 41, 42 arranged there.

In Figure 3 it can be seen that each section 2a, 2b and 3a, 3b of the longitudinal sides 2, 3 of the solid block 40b separated by the transverse center plane 7 has two cams 12, 13; 14, 15; 43, 44; 45, 46, the cams 12; closer to the transverse side 4 or 5 of the molded block 1; 15; 43; 46 with the cams 13; 14; 44; 45 of the respective counter-stone (in FIG. 3 solid stone 40c or half-stone 40a) a pair of teeth

48, which is spaced apart from the pair of teeth 49, which is the cams 13; 14; 44; 45 with the cams 10; 15; 43; 46 of the respective counter stone (solid stone 40 c or half stone 40 a in FIG. 3).

The transverse side 4, 5 of the half stone 40a and the solid stone 40c have cams 10, 11; 41, 42, the cam 11 of the solid stone 40c closer to the longitudinal center plane 6 with the the cam 41 of the half-stone 40a further from the longitudinal center plane 6 forms a pair of teeth 60 which is spaced apart from the pair of teeth 61 which forms the cam 10 of the solid stone 40c further from the longitudinal center plane 6 with the cam 42 of the half-stone 40a closer to the longitudinal center plane 6, and wherein the Longitudinal center plane 6, closer cams 11 of solid stone 40c, together with cam 42 of half stone 40a, closer to longitudinal central plane 6, forms a third pair of teeth 62.

A free space 50, which is designed as a water drainage shaft 51, is left between the pairs of teeth 48, 49. In this water drainage shaft 51, for example, rainwater can run between the cam 14 and the long side 2 of the solid brick 40b and the cam 43 and the long side 3 of the solid brick 40c to the undersides 30 of the solid bricks 40b, 40c. Channels 52 are arranged on the undersides of the solid bricks 40b, 40c. Via which the rainwater drains or seeps under the bandage 40.

FIG. 4 now shows the perspective view of a solid brick la with channels 52, which are arranged mirror-symmetrically to the transverse center plane 7. A half-stone 40a with a channel 52 can be seen in FIG.

FIG. 6 shows a variant of the solid stone la. According to this variant, the solid brick la has recesses 53 which are formed as recesses 54 at the transitions of the long sides 2, 3 into the transverse sides 4, 5 and as recesses 55 in the middle of the long sides 2, 3. FIG. 7 shows a half-stone 40a, which also has recesses 53, which are designed as recesses 54 at the transitions of the long sides 2, 3 into the transverse sides 4, 5. FIG. 8 now shows a bandage 60 consisting of two solid bricks 56, 56a and a half brick 57 according to FIGS. 6, 7. Here it can be seen that greening islands 58 are formed by the recesses 53. The greening islands 58 are each formed by four recesses 54 or one recess 55 and two recesses 54. The greening islands 58, which according to one embodiment variant are only filled with gravel, loosen up the strict longitudinal alignment by their regular arrangement and thus allow the use of the shaped stones 1 even in areas in which a shaped stone 1 laid in a longitudinal association would not be an option for aesthetic reasons . Thus the area of application of the shaped stones is expanded by the greening islands 58.

According to a variant, not shown, it is provided that further channels branch off from the channels 52 on the underside 30 of the shaped stones 1 to the greening islands 58, in order to ensure an optimal supply of the plants used in the greening islands 58 and an optimal absorption of the water .

FIG. 9 shows a further embodiment variant of the shaped blocks 1. In this variant, the spacing or toothing means 9 are not arranged mirror-symmetrically to the longitudinal center plane 6, but offset to the longitudinal center plane 6, in order to insert half-stones laid in the edge area on the solid blocks contacting their longitudinal sides 2, 3 in both Support directions of the movement arrow 59.
