The invention relates to pavement material for traffic areas which consists of artificial stone material. Said pavement material is characterized by the following features: (a) first pavement elements are provided which have a single first shape or several different shapes; (b) second pavement elements of a single second shape or several different second shapes are provided in individual areas of the pavement material; (c) third pavement elements are provided which have a single third shape or several different third shapes; (d) the second pavement elements are at least mainly enclosed by several third pavement elements in such a manner that a transitional zone is formed to the subsequent pavement area of the first pavement elements; (e) the second shape or the second shapes is (are) different from the first shape or the first shapes, and the third shape or third shapes is (are) different both from the first shape or first shapes and the second shape or second shapes.

Abstract:
The invention relates to a method and a device for producing concrete paving stones (10) which have at least one projection (12) on at least one outer face (11). This projection ensures that a joint of a predetermined width is formed between adjacent paving stones when they are laid on a surface. The at least one projection (12) is formed by a rear elastic deformation of a concrete paving stone blank whilst it still wet during stripping. The inventive device comprises shaped webs (14) with cavities or recesses (15) which correspond to the projections (12) to be formed. During the production of the concrete paving stones (10) including the projections (12), these shaped webs (14) are simply withdrawn from the concrete paving stone blanks whilst the blanks are still wet.
Abstract:
The description relates to an artificial stone (1) for stabilising traffic areas in the open. In order to form broad seams between stones laid beside one another, this stone has one-piece identical spacer projections (5, 6) on its side surfaces (3, 4), the superimposed free end surfaces of the spacer projections (5, 6) have a tooth (10) and a recessed bearing surface (11) side by side for engaging with the adjacent stone (1). The sequence of tooth (10) and recess (11) for all spacer projections (5, 6) around the stone is identical; in a stone, the effective length of the individual side surfaces parallel to the laying plane is a single or whole-number multiple of a shortest effective length; each side surface section of the shortest effective length (3, 4) has a spacer projection (5, 6) and the median axis (12) of all spacer projections (5, 6) lies at the centre of the relevant side surface section. Here, the bearing surfaces are designed as a tooth gap (11) corresponding to the size of the tooth (10) and surrounding it on both sides to the laying plane and the relevant side surface, the flanges of the tooth (10) pointing in said direction on the one hand and the tooth gap (11) on the other form an angle of at least 90 DEG and the bisecting line (42, 43) of said angle is substantially parallel to the normal to the relevant side surface.
Abstract:
The invention concerns a floor covering made up of pentagonal concrete moulded parts (F1) which fit together with joints between them. In order to give a floor covering of this kind an appearance similar to that of a floor covering made of irregularly shaped natural stones, while at the same time ensuring that the moulded parts are easy to manufacture and easy to lay, the invention calls for each part to have two adjacent straight sides (1, 2) of equal length with an obtuse angle between them, two concave sides (3, 4) of the same length and with the same curvature on each side of the two straight sides and, between the two concave sides, a convex side (5) twice as long as the concave sides (3, 4) and with the same curvature as the concave sides. Each set of three parts forms a group, the straight sides (1, 2) fitting against each other to form a star-shaped joint (6). The outwards-facing convex side (5) of each group of three fits into the concave sides of the adjacent groups of three and vice versa.
Abstract:
The invention has the following characteristics: the paving stone system may consist of paving stones having any desired outer contour; the paving stones have one or several channels (2) at their bottom side; these channels may also cross each other; one or several partial depressions (5) are arranged on the bottom side of the paving stones; one or several vertical spacing cams (3) are located on the sides of the paving stones, as well as one or several downwardly open depression (1); a continuous chamfer (4) is arranged at the top side of the paving stones.
Abstract:
The invention relates to a slab lining, in particular for a water-tight and/or acid- or alkali-resistant floor or wall covering, consisting of slabs (2) with a polygonal contour. Each slab has a flat upper face (20) and a flat or textured lower face (21) set in a bed of adhesive material (3). Flanks (22) extend from the lower face (21) to the upper face (20). The flanks (22) of adjacent slabs (2) delimit joints (10) which are also filled from bellow with the adhesive material (3) and/or from above with a special grouting material (30). The flanks (22) are provided with a texture which increases the surface area of the top face and allows the adhesive material (3) or the grouting material (30) to pass through the joints (10). The texture consists of a plurality of adjacent depressions (23) or projections (24) whose longitudinal axes extend parallel to each other essentially perpendicular to the longitudinal direction of the flanks (22). The cross-section of the slabs (2) perpendicular to their plane is conical with inclined flanks (22).
Abstract:
A module for use in constructing a pathway for traffic comprises a base member that defines a lateral groove disposed at its perimeter edge and extending along a first end, and a tongue structure disposed at its perimeter edge and extending along a second end. The tongue structure is received in the lateral groove and comprises a plurality of tongue portions that includes a first type of tongue portion and a second type of tongue portion disposed in alternating relation along the length of the tongue structure, to thereby define a throughpassage for receiving a securing rod. The first and second tongue portions have no vertical overlap one with the other. To form a pathway for traffic, the modules are placed in perimeter-edge to perimeter-edge relation, with the tongue structure of the modules inserted into the lateral groove of an adjacent module, and are secured together by the securing rod.

Generally L-shaped, square, rectangular, triangular, hexagonal, parallelogram and other-shaped paving stones with inter-fitting vertical spacers forming serpentine side contact surfaces that provide enhanced stone-to-stone interlocking in both water-permeable and water-impermeable paving installations.
Abstract:
A structural wall unit system includes a plurality of wall units having at least one face being a rotational tessellation. The face has at least two irregular sides extending therefrom. Each side of the wall units have at least one spacer or connector configured to engage other wall units. The structural wall unit system also includes a plurality of starter course units, where each starter course unit has a portion of a primary rotational tessellation element having at least one irregularly shaped side that is an image of the first side or the third side. Each irregularly shaped side of the starter course units have at least one spacer or connector configured to engage the wall units, and the starter course units have at least one straight side. The starter course units and the wall units are configured for assembly as a structural wall having a natural, random appearance.
