Abstract:
A concrete paving stone adapted to be disposed in circular and elongate paving configurations. The paving stone includes at least two side walls and a substantially planar upper face, each of the side walls being an arched side wall and including an elevated face at a center region thereof which comprises an abutting surface and two associated wedge surfaces adjoining the abutting surface on both sides thereof. The associated wedge surfaces extend from the abutting surface to an associated arched side wall. The elevated face further extends across a substantial portion of a length of the associated arched side wall and is effective for creating a fixed abutment between adjoining arched side walls of adjoining paving stones in a paving configuration.
Abstract:
A paving stone configured to be arranged in a paving stone bond in an area-covering grid-shaped lattice of paving stones comprised of lattice elements. The paving stone has side walls and includes a plurality of spacers disposed on the side walls thereof. Each of the spacers has an abutting surface adapted to be positively joined to a respective abutting surface of a spacer on an adjacent paving stone in the lattice of paving stones. In this manner, a crossing joint is formed between the paving stones. The abutting surface of each of the spacers includes a stepped contour for positively meshing with a corresponding stepped contour on the respective abutting surface of the spacer on the adjacent paving stone, the plurality of spacers being disposed on the side walls of the paving stone such that the stepped contours of their respective abutting surfaces are identically oriented in either of two rotational directions defined around the side walls of the paving stone.
Abstract:
A paving stone (10) is provided which includes individual sectors (20, 30) of uniform size and shape. Each sector (20, 30) is joined together to form a unique pattern such as a cross-paver (10), a Z-paver (110) or an S-paver (210). Some sectors (20, 30) are tips sectors (20) which attach to only one other central sector (30) and some sectors (20, 30) are central sectors (30) which attach to two or more other top sectors (20). Each of the sectors (20, 30) extend between a common top surface (40) and a bottom surface (50). An outside surface (60) defines a periphery of the paving stone. A V-groove (80) is positioned on the top surface (40) at margins between adjacent sectors (20, 30). The V-groove (80) includes a crease (82) on a bottom thereof which encourages vertical crack propagation from the top surface (40) through to the bottom surface (50) in a plane when a appropriate force-applying tool is utilized. When this occurs the paver (10) is modified into a paver of a different shape. Spacers (66) on the outside surface (60) of the paver (10) provide interstices (90) between adjacent pavers (10).
Abstract:
A set of shaped stones for paving ground areas with wide gaps between the shaped stones is provided which comprises first and second shaped stones, with the second shaped stones having a smaller plan view area than the first shaped stones. A plurality of integral spacing projections are provided on the periphery of only one of the first and second shaped stones for defining the wide gaps in the shaped stone pavement.
Abstract:
A unique shaped paving block having a top face, bottom face and 18 flat sides that permits its ready placement by being rotated 60 degrees or less to orient with blocks already in position. The six groups of three exterior and interior sides or faces with an intermediate joining side face provides lock points so that the block is especially usable in high loading areas such as industrial applications and applications at airports.
Abstract:
An arcuate paving block assembly comprising two outer transitional blocks (1) with four arcuate sides, wherein two adjacent sides (10, 18) are curved inwards and the other two sides (19, 20) are curved outwards in order to form a continuous transition from one arc to another; adjacent thereto on both sides an equal number of arc blocks (2, 3, 4; 2a, 3a, 4a) constructed to be mirror images of each other and symmetrical or mirror image shaped keystones of apex blocks (5, 6, 5a, 6a; 7, 7a, 8) which together make up the entire length of an arc, the whole being such that when laid the two outer edges (10) of the transitional blocks (1) enclose an angle of 90.degree. and the height (H) of all the blocks measured at right angles to an imaginary baseline (S) through the lower corner of the transitional blocks (1) is the same. Herein the blocks have a lower portion remote from the top tread surface which extends further in the horizontal direction and an upper portion of less extent in the horizontal direction, wherein the lower portion of the radial sides (21) of the arc blocks and crown blocks and the outwardly curved sides (19, 20) of the transitional blocks (1) are provided with vertical or perpendicular projections (14, 15) and the edging of the upper portion has lateral surfaces which are irregularly formed in the same way as a natural stone.
Abstract:
The paving stone set consists of stones 11-16 each with six lateral boundary surfaces 1-6, 17-22. Four of these boundary surfaces 1 and 4; 3 and 5; 18 and 21; 19 and 22 are parallel to one of the other of the four surfaces, while the remaining two surfaces 2 and 6; 17 and 20 define planes which intersect at an acute angle. On the straight edges, the stones 11-13 are laid alternatingly. A joint pattern is created with expansion joints, which do not stand vertically to the support joints. The expansion joints are formed from two wedges directed opposite to one another, and therefore have an effect which is irregular in comparison with the support joints. The slotted boundary surfaces 2, 6 make it possible to lay the stones 11-13 according to the sloping angles selected in curves with small radii chosen as desired, whereby the wedge-shaped joints close gradually. The stones 14-16 serve as a supplementary curve set, and make possible the laying of Roman arrow patterns, as well as an Archimedean spiral. The paving stone set can be quickly and simply laid down without trimming the stones.
Abstract:
A concrete paving stone having single flags held together with a number of concrete ribs between adjacent stones such that the ribs will resist breaking during ordinary handling but will break upon the application of vibration after the paving stone is laid on a level sand bed to thereby provide a number of unconnected flags.

Paving through which grass may grow, e.g. for parking areas or for dikes, is formed by abutting grooved concrete etc, blocks of square, rectangular, hexagonal or octagonal shape, the vertical faces of each block having grooves 9, 10 shaped to leave square, circular or other holes between blocks, while the top face of each block has edge grooves or chamfers 6, 6' and intersecting grooves 4, 5 which communicate with the grooves 9. Interlocking tongues and grooves may be provided on the flat surfaces 8. The paving may include diagonally-halved blocks. In a modification each grooved block has a vertical central aperture.
