Abstract

The block (10) has a first pair of spacers (19,20) on two opposite sides (13), and a second pair of spacers (17,18) on the other opposite sides. Spacers within a pair of offset relative to each by one spacer width, so that their sides engage with spacers of a neighboring block. The first pair is offset relative to a line (15) cutting across the block. The second pair is offset relative to a line (16), which is offset relative to the cross line by one spacer width (b).

Description

The present invention relates to a paving stone the features of the preamble of claim 1.

Such paving stones are known. The on the side surfaces the paving stones arranged laterally protruding Spacers are used when placing the Paving stones to provide defined joints to prevent seepage of rainwater. Here it is known to design or arrange the spacers so that when adjacent stones are placed next to each other Place spacers in side contact with each other, see above that there is a gear effect that misplaced that Patches stabilized accordingly. Support on the face the spacers on the side surfaces of the neighboring ones Stones or on flat surfaces of spacers of the neighboring stones. In this way - despite the planned joint space - a plaster with Create compound effect.

With most known paving stones you can however - due to the shape and / or location of the spacers - create only certain laying patterns, so the versatility of using such Composite stones left something to be desired.

A paving stone with the features of the generic term of Claim 1 is known from DE 295 16 425 U. at this known paving stone are on two opposite Side surfaces two pairs of spacers arranged. The spacers themselves are arranged all around, i.e. they always have the same distances to the corners of the Stone on. This allows only very specific laying patterns create.

The present invention is based on the object to create a paving stone of the type specified, the With a large joint space in the composite, a particularly large number of laying patterns allows.

This object is achieved with a paving stone of the specified type by the characteristic features of the Claim 1 solved.

The term "paving stone" used here is intended in addition to Cobblestones in the shape of a cube, cuboid too cover those in the form of a plate. The term is thus to be interpreted comprehensively. It is essential that the Stone next to a top and an opposite Underside has four side surfaces, each of which is two opposite and right angles with each other form.

The term "pair of spacers" means that a spacer on two opposite side surfaces located that are associated with each other and together form a pair of spacers.

For example, in the solution according to the invention Stone with a rectangular top that is different has long side faces on the opposite long side surfaces two first pairs of spacers, while on the opposite short side faces a second pair of spacers is arranged. A paving stone with a square top has each two pairs of spacers on two opposite side surfaces. With even larger stone formats, the number increases of the spacer pairs accordingly.

The one on the opposite side faces arranged spacers of a pair are around one Spacer width offset from each other. hereby the spacers can be arranged accordingly Spacers of a neighboring stone in the side system occur so that there is a corresponding gear effect (Compound effect) results.

The peculiarity of the paving stone designed according to the invention is now that the spacer pairs of a stone no identical position with respect to a fixed point on the stone, for example its center, its center lines, corners etc., have. So is a first Spacer pair with respect to one cutting the stone Line staggered. With one made up of two square ones This is the cornerstone of the rectangular stone Line, preferably a line quartering the stone, which is also on the two rectangular stones square stone applies. With larger formats it is preferably one in eight, sixteen, etc. parts of the stone dividing line. These lines can be used as grid lines are viewed that divide the stones into individual squares, in which the rectangular stone eight squares, which is made up of two rectangular stones composite square stone sixteen Squares, etc.

The other first pair of spacers is now not in one the position corresponding to the first pair of spacers, but the stone cutting line of one pair the first pair of spacers has the stone opposite intersecting line of the other pair of the first pairs of spacers a distance increased by the width of a spacer (b) from the center line of the stone.

As already mentioned above, this is namely the case Rectangular stone on its opposite long side surfaces two first pairs of spacers. A couple of them is preferably arranged so that its spacers offset with respect to a line quartering the stone are. The other pair is arranged so that its Spacers with respect to one another quarters the stone Line preferably to the stone corner around the width of a spacer shifted line are offset. These two spacers are therefore closer to the associated one Steinecke arranged as the spacers of the a couple. Furthermore, both first pairs of spacers are like this arranged that with respect to the center line of the Stone two internal spacers on one side and two outer spacers on the opposite Side surface result.

Due to the shifted position of the first pair of spacers compared to the other first pair of spacers, it is achieved that a rectangular stone with its long side in two different layers on the other rectangular stone can be. In the normal position (with the appropriate position in relation to the other stone) step the two inside Spacer of one stone with the two outer spacers of the other stone in lateral Investment. At a position rotated by 180 °, the two spacers with the long side surface of the to be created Steines again with the two spacers the other stone in side contact, but in this Trap are the two spacers of the to be created Do not stone both within the other's spacers Stone, but there is only one inside, while the other is outside. So while in the former case results in a so-called "bracket effect", which leads to a fully integrated effect results in the second Case also a positive fit of the two Spacers, but only so that a relative displacement between the two stones is still possible if there are no other neighboring stones. So it will achieved a "semi-composite" with this type of system.

The following therefore generally applies according to the invention:
In the case of larger stone formats, in which at least two pairs of spacers are arranged on the opposite side surfaces, there is a shift by one spacer width between the reference lines of at least two pairs, in such a way that these two pairs have two internal ones on one side surface and two on the one opposite side surface result in two outer spacers. In this way, on the one hand, the desired bracket effect when applying in the normal position and the desired semi-composite when applying in a position rotated by 180 ° is achieved.

The rectangular stone is preferably designed so that the Spacers on the opposite short side faces arranged second pair with respect to the bisector or staggered centerline of the stone are.

The stone has a square top and bottom and is made up of four square foundations, so that a total of sixteen square grids are formed, so are always two on two opposite sides Spacer pairs arranged. There is one of each Pair in relation to a quarter of the surface of the stone Line offset by a spacer width, while the other pair also by a spacer width is offset from one another, but by one to a line quartering the surface towards the corner by one Spacer width shifted line. Here too is the arrangement so that there are two internal spacers on one side surface and two external spacers result on the opposite side surface. The desired bracket effect and the desired semi-composite are therefore also guaranteed here.

Has a paving stone of such a format that on his opposite pairs of spacers are arranged, preferably of these three pairs two pairs two inside and two outside Spacers on. Therefore, between these two pairs the desired bracket effect is achieved.

With the training and positioning of the invention Spacers can be a variety of laying patterns Realize in a full and half network, for example Runner bandages, elbow bandages, herringbone bandages etc. The paving stone designed according to the invention draws is therefore particularly versatile out.

The shape of the spacers is for the invention Solution not critical. It is only important that the spacers of paving stones put together can be interlocked so that a full network can be achieved lets, i.e. the spacers must be shaped like this be in side contact with each other, i.e. have positive contact. In a special embodiment of the invention they are tooth-shaped and have flattened tips. Here the side kick Sloping surfaces with the sloping surfaces of the spacers adjacent stones in contact while the flattened Tips on the side surfaces of adjacent spacers support. In a further preferred embodiment the spacers have an expanded base, on which the actual spacer is located, the in this case also be tooth-shaped and may have a flattened tip. In this embodiment support the flattened tips of the spacers of neighboring stones on the flat surfaces the base, i.e. not on the side surfaces themselves.

The solution according to the invention wants with so few spacers as possible to get as large a joint space as possible to obtain. In this respect there is preferably a pair of spacers only from one spacer on one Side surface. However, it is not excluded that a pair of spacers each two or more spacers has a side surface, for example in the form of two or more teeth, then with one or more spacers (Teeth) on the side surface of the neighboring one Get in touch with the stone. Such an embodiment should only be used in exceptional cases, if a particularly large bond effect or stability is desired since this eliminates the need for joint space.

For recognizing the external or internal spacers one side surface (bracket effect) has the Paving stone designed according to the invention preferably a marker that, for example, as the preceding Section can be formed on the side surface.

The invention is explained in detail below using exemplary embodiments in conjunction with the drawing. Show it:

The paving stones shown in the figures exist made of concrete and are essentially plate-shaped, being a top and a bottom and four Have side surfaces that form right angles with each other. The stones therefore either have a top view a square or a rectangular shape.

Figure 1 shows a not falling under the invention square foundation stone 1 with a Top 2 and four sides 3. This cornerstone is in the rectangular stones shown in Figures 2 and 3 twice and in the square stone shown in Figure 4 included four times.

Stone 1 is defined by two center lines (bisector) 4, 5 divided into a grid with four squares. These center lines 4, 5 form reference lines for the arrangement of spacers on the side surfaces, at which are sections protruding from the side surfaces that covers the entire height of the side surfaces or extend only over part of this height can. In the paving stones of Figure 1 there are four spacers 6, 7, 8, 9 present in the form of teeth are designed with a flattened tip, i.e. two have sloping side surfaces and a flat end surface. The side surfaces are used for contact with the side surfaces the spacer from neighboring stones if the end faces are on the side faces of the neighboring ones Support stones.

Two spacers 6, 7 or 8, 9 on two opposite Side surfaces form a pair of spacers. The spacers a pair are arranged so that they with respect to a connecting both sides Line are offset from each other. Both Spacers 6, 7, this reference line is the center line or bisector 4, while the reference line in the Spacers 8, 9 is formed by a line 10 that with respect to the corresponding center line or side bisector 5 shifted by a spacer width "b" is.

Figure 2 shows two designed according to the invention stacked paving stones 10 in the top view. Both stones are identical and have a rectangular top 11 and four side surfaces, which consist of two long side surfaces 12 and two assemble short side surfaces 13. The spacers are designed accordingly as with the paving stone Figure 1. Each stone is made up of two square ones Foundation stones according to Figure 1 together. On the two opposite long side surfaces 12 are two spacers 17 and two spacers 18 are arranged. The short side surfaces 13 each have a spacer 19 or 20 on.

Again, the spacers are on opposite Side surfaces are offset relative to each other again with reference lines arranged. In the pair of spacers on the right in FIG. which consists of the spacers 17 and 18, the reference line is a quarter of the surface of the stone Line 14, while this is for the pair of spacers that are on the short side surfaces is arranged with respect to the Spacers 19, 20 bisect the surface of the stone Line 15 (center line) is. The one on the left in the figure Pair of spacers on the opposite long side surfaces, which consists of the spacers 17, 18 has as a reference line, line 16, which is opposite the quartering Line 14 around the width "b" of a spacer to the corner is arranged offset. It surrender to this Way on the lower long side surface 12 in the figure two inner spacers 18 and on the one in the figure top side surface 12 two outer spacers 17. Be two stones in the one shown in Figure 2 Kind of put together, so the two clasp outer spacer 17 of a stone the two inner spacer 18 of the other stone, so that both stones are fixed in the transverse direction of the figure and there is a full network.

By the offset of the pair of spacers shown on the left in FIG. 2 17, 18 compared to that in the figure on the right spacer pair shown, it is possible to the in Figure 2 stone shown above not only in the position according to Figure 2, but also in that shown in Figure 3 Position on the lower stone. This in Figure 3 shown position of the upper stone is opposite to that of Figure 2 rotated by 180 °. You can see that in this position the two spacers 17 of the lower in the figure Side surface of the upper stone is now to the right of the two spacers 17 of the upper side surface of the lower stone. In this position it is true also an installation of the inclined surfaces of the spacers, however, both stones can be moved in the transverse direction in this position move relative to each other. So it won't the full composite achieved in Figure 2, but only one Semi-composite reached.

In the embodiment shown in Figures 2 and 3 of the paving stone is for marking the two outer spacer 17 a mark in the form a projecting element 21 on the side surface between the two spacers. This mark serves as a laying aid.

Figure 4 shows a paving stone 30 with a square Top 31 and four equally long side surfaces 32. This Stone is made up of four square foundation stones of Figure 1 together. Two opposite side faces have two pairs of spacers, each consisting of the Assemble spacers 35, 36 and 37, 38.

Again, there is a pair of spacers with respect to the stone corner is offset from the other. While the pair of spacers 35, 36 on the right in FIG. 4 are relative to a reference line quartering the surface of the stone 33 is arranged offset, that is in FIG. 4 left pair of spacers offset with respect to a line 60 arranged opposite the quartering of the area Line 33 shifted by a spacer width "b" towards the corner is. This results in the above in connection described with the rectangular stones two different Investment opportunities. Also the stone of Figure 4 has a mark 39 in the form of a projecting Ab-. cut that the two outer spacers 35th or 37 indicates.

The paving stone 40 shown in Figure 5 with a rectangular Top 41 and two long side surfaces 42 and is two short side surfaces 50, apart from the shape the spacer, correspondingly designed as that in the Figures 2 and 3 shown rectangular stone. The spacers 46, 47, 48, 49 have a broadened base here, of which the tooth-shaped spacer with flattened Tip runs out. Support when putting stones together the flat end faces of the spacers on the flat surfaces of the base, i.e. the end faces do not contact the side surfaces 42, 50. On this way becomes one compared to the embodiment of the figures 2 and 3 enlarged joint between adjacent stones reached. The position of the spacers corresponds to of the paving stone of Figures 2 and 3, also here again three reference lines play a role, namely once the bisector 44, a line quartering the surface 43 and one opposite the line 43 by a spacer width "b" offset line 45. There are two internal Spacers 47 and two external spacers 46 on the opposite long side surfaces 42nd

FIG. 6 shows a top view of three in a group of runners laid stones that correspond to the stones of Figures 2 and 3. It can be seen that the lower one shown in the figure Stone with its two outer spacers each a spacer of the lower side surface in the figure of the two stones above. At 21 is the marking for the so-called big "bracket" is shown.

FIG. 7 shows three rectangular stones 10 from FIGS. 2 and 3, the stone on the right in the figure is perpendicular to the two left stones of the figure is arranged. Here too grips the right stone with its two outer ones Spacers the two on the front of the left Spacers arranged stones, so that there is a corresponding Bracket effect results. At 21 is the so-called large "bracket" indicated.

In conclusion, it should be noted that the in the figures 2 to 7 paving stones shown in terms of their dimensions not relative to the square stone of Figure 1 are shown to scale. So are the side lengths of the stone of Figure 4 relative to the side lengths of the Stone of Figure 1 shown too short. In reality they would have to be extended by the size of a joint so that the stone of Figure 1 four times in the stone of Figure 4 plus Fugue is included. With the rectangular stones shown the length: width ratio is also incorrect shown. The length of the stone must be twice the side dimension of the stone of Figure 1 plus a joint width correspond. These deviations in the presentation are effective however, does not refer to the invention in question out.

Figure 8 shows a plan view of three laid in the bandage Rectangular stones 10. The representation is not to scale. It can be seen that the type of installation shown here is the upper one transverse stone with its two spacers 50 a small "bracket" that forms the spacers 51 from embraces two stones. This little "bracket" is the large "bracket" indicated by the projection 21 across from.

The lower left stone in FIG. 8 encompasses his 21 indicated large "bracket" the two spacers horizontally on the faces of two more in the figure arranged stones.

It can thus be summarized that according to the invention Paving stone is created, the laying pattern as in Allows normal stones without teeth, but in full.
