Abstract:
The invention relates to horizontally and vertically linked paving stones (10). According to the invention, projections (18) and recesses (19) are provided in the area of the bottom part (16) of the paving stones (10) used for a paved surface in order to link said paving stones horizontally and vertically. These projections and recesses engage with each other with a positive fit so as to interlock adjacent stones in a horizontal and vertical direction. The paving stones (10) are characterised in that the width of the joints (32) formed between adjacent paving stones (10) increases in a downward direction so as to form a gap which diverges downwards. This means that the material used for filling the joints can be introduced efficiently and reliably as far as the underside.
Abstract:
The invention concerns a concrete material paving stone having an integrally flat surface and two strip-shaped support lugs which are vertically disposed on each side surface and form gaps between adjacent paving stones in the composite structure. According to the invention, in order to prevent unintentional displacements parallel to the plane in which the paving stones are laid, two support lugs (5) are symmetrically disposed on two adjacent side surfaces (3, 4) of the paving stone body (2) with a centre distance (a', a'') relative to planes of symmetry (s1, s2) passing through the centres of the adjacent side surfaces (3, 4), the support lugs (5) having a thickness (b) and width (c). Symmetrically disposed on the respective opposite side surfaces (6, 7) are two support lugs (8) which are offset in the direction of the associated corner regions, have a centre distance (d', d'') relative to the planes of symmetry (s1, s2) and a thickness of substantially b/2 and a width (c). When the paving stones are laid in a crosswise design, depending on the association of the side faces, the support lugs (5) can be inserted between the support lugs (8) or, in a stretcher arrangement, they can be inserted between the support lugs (8) and engage in clamp-like manner over support lugs (8) of adjacent paving stones (1).
Abstract:
A method and apparatus for forming a concrete block, particularly but not exclusively a composite block with a reflective facia portion. The block is formed by a dry-cast technique, in which mixture for forming the block has a water/cement ratio less than or equal to 0.35, in combination with application of a compaction force so that the resultant block complies with compressive strength requirements set out in BS 6717: Part 1: 1993.
Abstract:
The invention concerns a paving stone made in particular of concrete, with an outer, preferably hexagonal, profile whose lateral faces (2, 102, 203) face each other when the stone is laid on the road surface or the like and in the laid position can brace each other at least in sections. The lateral faces (2, 102, 203) of the hexagonal stone (1, 101, 201) are each provided with a bracing pattern (3, 103, 104, 215) which ensures that a reliable seal is created in the region of the gap between hexagonal stones (1, 101, 201). Recess cuts (105, 106) and/or a horizontal peripheral groove (205) can in addition be provided in the lateral faces (2, 102, 203), thereby improving the stability of the join and the tightness of the join against penetrating contaminants in the gap region.

Abstract:
In a flat square slab with a smooth surface and tongue-like attachments perpendicular to the side surfaces, in order to provide a large number of layout combinations, each side surface (26, 27) has two projections (22, 22', 22''), wherein each projection (22) is formed on a corner edge (23) of two adjacent side surfaces (26) and one projection (22') is formed on the same side surfaces (26) at the other corner edge (24) and the projections (22'') are arranged at a slightly greater distance from the edge corners (24, 25) on the other two side surfaces (27) than the length of the attachments (22, 22') looked at from the smooth surface of the slab.
Abstract:
In order to produce a stable, highly water-permeable flooring with a plate-shaped paving stone, in particular made of concrete, recesses (3) with a substantially trapezoidal cross-section are provided in two opposite lateral surfaces (2) of the paving stone (1). The delimiting surfaces of the trapezoidal recesses (3) located next to each other have in their central area a further recess (5). Recesses (7) are provided in the centre of the lateral surfaces that extend transversely to the lateral surfaces (2) of the paving stone. Chamfers (8) are arranged at the corners of adjacent lateral surfaces (2) of the paving stone (1).
Abstract:
A paving assembly (1) comprises a plurality of paving elements (2) interconnected by a reinforcing and interconnecting mesh (5) of plastics material. Adjacent paving elements (2) are joined by frangible links (15) which assist in spacing the elements (2) to define interstices (9) to receive bedding sand. The links (15) have fault line (16) along which the links (15) may be broken to accomodate articulation between adjacent paving elements (2), on fitting. A mechanical interlock is formed when the paving is in place and the faces of the link posts (15) re-engage. In some cases a paving assembly (100) may comprise paving elements (101) which do not have a joining mesh.
Abstract:
A square edge recessed lug paver having recessed lugs that produce consistent joint size during installation without the use of additional pieces of equipment, while maintaining a square edge is described. The equipment and method to produce the square edge recessed lug paver is also described, where the recessed lug roller forms the recessed lugs of the square edge recessed lug pavers. The recessed lug roller includes at least one recessed portion and at least two compressing portions. The recessed lugs are formed on an uncut slug after extrusion of the slug.
Abstract:
A landscaping block having a block body with at least a first side surface, a second side surface, a third side surface and a fourth side surface, and opposed and substantially parallel top and bottom surfaces. The patio block having at least one spacer projection extending outwardly from each of the at least first, second, third and fourth side surfaces. The patio block having at least one spacer locator positioned along each one of the first, second, third and fourth side surfaces. The at least one spacer locator positioned along each side surface has a retaining surface shaped to receive a spacer projection, at least a portion of the retaining surface extending outwardly from the side surface.
