Stone paving
Description

The invention relates to a stone pavement according to the preamble of claim 1.

Stone paving is used to create paths and roads. For this purpose, rectangular or square shaped stones or shaped stones, for example with a zigzag shape, are usually laid flat next to one another so that a given area is covered. The shaped stones are usually made of concrete blocks and match the color of the concrete. This means that after laying the shaped stones, a path or road paving has a homogeneous appearance that is functional but offers no aesthetic appeal. Markings or markings on such paving are only possible by adding color or other accessories.

In addition to the paving stones described so far, there are also road or path surfaces that also consist of shaped stones laid together to form a stone pavement that depicts certain motifs or patterns. The shaped stones used there each have individual shapes that correspond to a motif to be depicted. The production of such stone paving stones is very time-consuming and expensive, since the shaped stones for each motif have to be produced individually and in very small quantities; mass production is hardly possible and not planned. It is therefore problematic, because very expensive, to cover larger areas with the latter shaped stones. This is all the more true if the stone pavement laid with them is exposed to high levels of wear and tear from traffic or pedestrians, so that individual or all of the shaped stones forming the motif have to be replaced.

The invention is based on the object of solving the above-mentioned problems and of offering a stone paving, in particular a composite paving, which on the one hand is favourable in terms of

production, durable and resilient and, on the other hand, meets high aesthetic standards and provides building owners with new alternatives.

This object is achieved in a cost-effective manner by providing a stone pavement according to claim 1, using a minimum of shaped stones and, consequently, a small number of molding tools required to produce the shaped stones.

In particular, the object is achieved by a stone paving, in particular composite paving, which consists of at least two types of shaped stones. These shaped stones include rectangular stones and angle or corner stones, which can be laid to form at least one regular octagonal ring.

According to one embodiment of the invention, several, in particular a number n, 8-corner rings are laid concentrically to one another, wherein the 8-corner rings are preferably arranged or laid around a, in particular 8-cornered, central stone.

According to the invention, the rectangular stones of the stone paving have a longitudinal edge of length L _s and a front edge of length B, while the angle or corner stones are defined by a front edge of length B, an outer edge of length L _A extending diagonally and an inner edge of length Li extending parallel to the outer edge and also diagonally. The length B of the front edge of the rectangular stones corresponds to the length B of the front edge of the corner stones. The shaped stones of the stone paving are laid or can be laid in such a way that all angle bisectors W of the corner stones laid in the paving meet at a common point Z located in the center.

According to one embodiment of the invention, the bisector W of a reference corner stone intersects the extension of the front edge of the reference corner stone at a point S, the point S being at a distance of length B _G from the outer edge of the reference corner stone, and the following relationships apply:

(II).

An essential point of the invention is that using only two different shaped stones, namely the rectangular stones and the angular corner stones, an elegant octagon can be formed that is open radially outwards, i.e. that can be extended at any time and is not limited in terms of size.

Such an octagonal shape cannot be produced using conventional state-of-the-art bricks, particularly rectangular, square or zigzag bricks.

In addition, a key idea of the invention is to form the stone paving in the form of several 8-corner rings arranged concentrically to one another. In an advantageous manner, the 8-corner stone paving can thus be extended at any time by one or more 8-corner rings. The design of a large area is thus possible at any time and in a simple manner without individual paving stones having to be specially shaped. It is also possible at any time to avoid an obstacle, such as a tree, by not laying individual paving stones in the area of the tree.

In the event that an area, such as a square, that is to be paved with stone does not have an octagonal shape itself, it is always possible to maintain the octagonal structure for a remaining paving area by simply laying segments or partial rings of the surrounding octagonal rings. After an obstacle, the octagonal structure can be resumed at any time. An integrative effect is the result and is the aim of the invention.

A key idea of the invention lies in the adherence to formula (I), which determines how the length L ₁ of an inner edge relates to the length L _A of an outer edge and the length B of the front edge, so that a gap-free and seamless stone

The formula (II) indicates how the length L ₅ of the rectangular stones must relate to the length L _A of the outer edge of the corner stones extending across the corner in order to produce such a pavement. At this point it should be emphasized that the terms "gap-free" and "gapless" in the context of this invention refer to inaccuracies in the fit of the shaped stones to one another, but not to a seamless installation per se.

At this point it should be emphasized that the stone paving according to the invention can be designed as a composite paving, for example by means of a tongue and groove design or by other composite-forming measures.

In principle, the laying of a stone paving according to the invention is possible with all rectangular stones and angled corner stones that satisfy the above definition; however, according to the invention, an embodiment is preferred in which the following relationship applies to the length Li of the inner, corner-extending edge (inner length) of the corner stones and the length L _A of the outer, corner-extending edge (outer length) of the corner stones:

and

Adhering to the specified length to width ratios results in a particularly advantageous overall aesthetic effect. At the same time, adhering to these dimensioning ratios ensures that the shaped blocks are manufactured particularly cost-effectively and that they can be laid efficiently and effectively. In addition, maintaining the correct thickness of the shaped blocks minimizes the potential risk of the shaped blocks breaking.

According to the invention, the angled corner stones each have an interior angle of 135° and, according to a preferred embodiment, are composed of two, in particular symmetrical, partial stones. The division of the corner stones takes place

preferably along the angle bisector; however, it can also be asymmetrical, for example diagonally from an inner corner to an outer corner or from an outer corner to the corresponding opposite outer corner, whereby the respective separated segment is attached to the corner stone as a "separate" part of the corner stone to form a whole, creating a special appearance.

According to a further embodiment, the octagonal rings are arranged around a, preferably octagonal, central stone with a diameter of 2 x β extending from one edge of the central stone at right angles to the opposite edge of the central stone, wherein starting from the central stone, every nth octagonal ring has η - 1 rectangular stones between the corner stones. The central stone can be composed of partial stones, in particular triangular ones.

According to the invention, if there are several rectangular stones between corner stones, these can be combined to form units. These units can be made in one piece or from one or more of the following sub-units.

The following subunits are provided: polygon, in particular triangle, quadrilateral, hexagon, octagon, parallelogram, trapezoid, rhombus, circle, circular segment or circular arc segment.

According to the invention, these subunits are joined together in such a way that they essentially form the planar structure of one or more rectangular stones arranged between two corner stones.

According to a further embodiment of the invention, the shaped stones have different colors. It is thus advantageously possible to design the 8-corner paving according to the invention in multiple colors or in bright colors and in this way to achieve an additional eye-catching effect. Likewise, in this way, different motifs can be represented in different parts of the 8-corner pattern according to the invention using different color representations, which are formed only from the shaped stones according to the invention. An additional application of color is therefore not necessary according to the invention.

Likewise, according to a further variant of the invention, it is provided that the octagon is provided with a pattern of colors and/or structured sub-units.

According to the invention, the sub-units, namely the aforementioned polygonal or ring or circular sub-units, are arranged in such a way that a pattern is formed from the laying joints surrounding them and/or from the area defined by them. This can be done, for example, by joining several circular arc segments together to form an overall circular arc. A honeycomb structure made up of an arrangement of hexagons or numerous structures created in a similar way is also possible. This is a very effective and cost-effective way of increasing the variety of variations of the 8-corner stone paving according to the invention, particularly in the case of large-area rectangular stones.

Further embodiments of the invention emerge from the subclaims.

rectangular octagon with equilateral edge lengths, which is composed of rectangular stones 20 and corner stones 30. The rectangular stones 20 and the angular corner stones 30 are arranged in octagon rings 40, with the innermost octagon ring 40 surrounding a central stone 60, which is designed in the shape of an equilateral octagon. The innermost octagon ring 40 consists only of corner stones 30 and has no rectangular stones 20. The octagon rings 40 are arranged around the octagonal central stone 60 in such a way that they encircle it uniformly and essentially concentrically, with the radius of the octagon rings 40 increasing with the distance from the central stone 60. The second octagonal ring 40 has a rectangular stone 20 between two corner stones 30, while the third octagonal ring 40 has two rectangular stones 20 between two corner stones 30. According to Fig. 1, four octagonal rings 40 are proposed. The reference number 50 and the bisector W in the left part of Fig. 1 indicate that the corner stones can consist of two symmetrical partial stones. This is provided according to this embodiment, but to improve the clarity of the illustration it is only indicated schematically here using an example.

Fig. 2 shows a section of a corner area of an octagonal ring according to the invention. A rectangular stone 20 is arranged next to a corner stone 30. The corner stone 30 is divided into two partial stones 50 by an angle bisector W.

According to Figures 1 and 2, it can be seen that the length L _A of the outer, diagonally extending edge of a corner stone 30 from an adjacent rectangular stone 20 to the adjacent rectangular stone 20 on the other side corresponds to twice the length L _s of a rectangular stone. Likewise, the length B of the front edge of the corner stones 30 and the rectangular stones 20 corresponds. This can be seen in a preferred manner from Fig. 3, where the length L _{s is} 175 mm and the width B is 210 mm.

Fig. 3 shows the length ratios to be taken into account in an arrow-like representation. B indicates the length of the front edge of a corner 30 or rectangular stone 20, while B _G (here: 420 mm) represents the distance of the intersection point S of the extension of the front edge of the length B of the reference corner stone with the bisector W. The extension of the front edge corresponds to the extension of the edge of a corner stone 30 that borders on a rectangular stone 20. According to Fig. 3, the length

ge B is exactly half the length B _G , so that the external length L _A (here: 350 mm) is twice the internal length Li (here: 175 mm). Regarding the width, the ratio La = B/0.6 and Li = B/1.2 applies.

Fig. 4 shows a dashed, more delicate design of an octagonal stone 30 according to the invention in the form of a corner stone variant I 33, which can be integrated into an octagonal stone paving according to Fig. 1 or 3, wherein the length B' of the front edge of the corner stone 33 is significantly reduced compared to the embodiment of the corner stone 33 from Fig. 3. This is indicated by the relatively short arrow B'. According to Fig. 4, the distance of the outermost outer edge of the fourth octagonal ring 40 from the center of the central stone 60 or the entire octagonal stone paving shown is selected as the reference value. The length of the dashed line corresponds to the inner length Li. This inner length obeys the formula

The remaining area 36 serves to accommodate another corner stone variant II 36. The outer length L _A of the corner stone variant II 36 corresponds to the aforementioned inner length Li of the corner stone variant I 33. The inner length of the corner stone variant II 36 obeys the formula
