Abstract:
The invention relates to an artificial stone floor element with a basic shape that corresponds to the combination of a plurality of square basic elements, especially to an angular floor element. The floor element includes projections and recesses along its peripheral sides of the basic element when seen from the centre of the respective top face of the basic element is substantially point-symmetric with respect to its mid-point. The floor element in further embodiments includes a profile that consists of three projections and three recesses.
Abstract:
First and second concrete pavers that are configured to form a paver system arrangeable in a herringbone pattern. A plurality of the first pavers and a plurality of the second pavers, which together form a kit of pavers, can be used to construct a permeable pavement with the herringbone pattern. The first and second pavers are preferably molded in a layer with the pavers arranged in the herringbone pattern. The layer can then be mechanically installed using suitable mechanical installation equipment.
Abstract:
There has been disclosed a cast stone (1) for securing traffic areas outdoors, with the stone (1) bearing at least one pair consisting of a protrusion (9) and an adjacent recess (10) substantially matching the form of the protrusion of the adjoining laid stone (1). It is provided that the tip of the protrusion (9) and the bottom (13) of the recess (10) have an integrally moulded layer (12) of material facing away from the associated lateral face (3, 4).
Abstract:
Ground covering element (2) having the basic shape of a square. On all four basic sides (4.1, 4.2, 4.3, 4.4), there is provided one engaging means (8.1, 8.2, 8.3, 8.4) each. Each of the engaging means is symmetric with respect to a central axis of symmetry (12). Opposite engaging means are mirror images of each other. Each engaging means is complementary with the engaging means on the two basic sides adjoining around the corner. On each of the four corner regions of the ground covering element, there is provided a protrusion (24) having substantially the shape of a rectangular, isosceles triangle or of an area element similar to this triangle with curved legs. By omission of the four protrusions (24), a ground covering element of the second type (42) is obtained which may be laid together with additional ground covering elements of the second type (42) or in combination with ground covering elements of the first type (2).
Abstract:
The invention relates to a construction kit made of concrete paving stones comprising substantially prismatic stone bodies of a uniform height and upright lateral surfaces. A plurality of stone paving stones (2) arranged in rows and having the same width in addition to the same or different lengths can be placed manually or placed by means of a machine with continuous or offset joints in said joint areas. A plurality of rows of paving stones that are arranged next to each other in a parallel position is used to form a rectangular or square packet that can be placed using a machine. The paving stones (2) have side surfaces (4) which have head pieces (2′) that are defined by a wavy line along part of their height and base pieces (2″) in sections, comprising domed areas (5) or projections jutting out laterally in relation to the head pieces (2′) extending along another part of their height. When the packets are assembled for placement in the vicinity of the end stones that make up a row of paving stones, they form a line of continuous joints or provide substantially winding-shaped joints (7) if so desired by replacing different sized end stones from adjacent packets that have been moved towards each other.
Abstract:
The invention relates to a ground covering of pentagonal shaped concrete slabs (F.sub.1) placed against another with joints. The shaped slabs are simple to produce and simple to lay and in order to give such a covering an appearance similar to a ground covering of irregular quarry slabs each shaped slab has two adjacent straight sides of equal length disposed at an obtuse angle, two adjoining concave sides of equal length and equal curvature, and a convex side disposed therebetween which is twice the length of the concave sides and has a curvature corresponding to the curvature of the concave sides. Together the three shaped slabs form a group of three, the straight sides abutting one another with the formation of a star-shaped joint. The outer convex sides of one group of three abut the concave sides of the adjacent group of three and vice versa.
Abstract:
There is provided an artificial stone for strengthening traffic surfaces in the open, in which the stone, in order to provide wide grooves between adjacently laid stones, is provided on its edge surfaces with integrally formed, completely identical spacer elements, the contacting free end surfaces of the spacer elements having, adjacent one another, a tooth and a recessed contact surface for the tooth of the adjacently laid stone; the tooth-recess sequence, in one peripheral direction of the stone, being the same for all spacer elements; the effective length of the individual edge surfaces of a stone, parallel to the laying plane, being the same as, or a whole-number multiple of, a smallest effective length; each edge surface segment which has the smallest effective length being provided with a spacer element; and the central axes of all spacer elements lying in the middle of the corresponding edge surface segment. The contact surface is formed as a tooth recess corresponding to the size of the tooth and enclosing the latter on both sides in the direction parallel to the laying plane and to the corresponding edge surface. The flanks of thee tooth and of the tooth recess enclose an angle of at least 90 degrees, and the bisector of the angle is essentially parallel to a perpendicular drawn to the corresponding edge surface.
Abstract:
Shaped slabs (10) made of concrete for forming groundcoverings have spacers (15 to 20) on their edges with which the shaped slabs are braced against one another when the groundcovering is completed. This bracing of the shaped slabs (10) on their spacers (15 to 20) determines the permissible traffic weights such a groundcovering may carry. This means that different shaped slabs have to be provided for groundcoverings which are suitable for heavier traffic weights. The invention is concerned with creating a universal shaped slab (10) which can be used for different traffic weights and therefore suggests shaped slabs (10) the spacers (15 to 20) of which being arranged on the side faces (11 to 14) of said shaped slabs (10) such that depending on the relative positioning of the side faces (11 to 14) when laying the shaped slabs (10), said spacers (15 to 20) are either interlocking or abutting. This way, wide or narrow joints can alternatively be formed between adjacent shaped slabs (10).
Abstract:
The interconnecting paving stones are provided on at least two opposing sides with outwardly tapering teeth. On one side of said stones, the front sides of said teeth are provided with indentation keys, and on the other side, with indentation grooves. Moreover, the flanks of one row of teeth comprise spacing bosses. An interconnecting paving stone can have the configuration of a rectangular stone and can comprise three teeth on each of its longitudinal sides and either a projection or a recess on the narrow sides.The interconnecting paving stones can be used either for the construction of bicycle lanes with increased smoothness, in which case said teeth engage with each other, or as interconnecting lawn stones, where respective teeth adjoin and interlock by means of said indentation keys and grooves.
Abstract:
A ground covering slab is subdivided into neighboring preformed individual stones interconnected along rupture zones of which at least parts extend non-rectilinearly from one edge of the slab to the opposite edge of the slab as seen in plan view and the preformed individual stones are of at least two kinds differing in size distributed throughout the slab.
