Abstract:
A paving element has a body with oppositely directed major faces interconnected by a peripheral side wall. One of said major faces is generally planar and has at least one set of a plurality of predefined areas formed thereon. Adjacent areas of the set have a surface finish to provide a contrasting visual effect relative to other areas of the set. The finish and disposition of the areas is configured to provide a representation of abutting orthogonally disposed surfaces so that when a plurality of such sets is arranged in seriatim, a visual impression of stepped surfaces at different levels is provided.
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.
Abstract:
A slab element for covering the ground is made e.g. of concrete and forms as a single piece. It has a head portion and a stem portion meeting at a notional meeting surface. The element is delimited by two opposite end faces of equal length joined by sides that form angled traces about a longitudinal axis common to the head at the stem, each said angled trace being formed by a succession of sides comprising at said head an inclined side face inclined in one direction relatively to the axis, a lateral side face extending lengthwise with respect to the axis and another inclined side face inclined in the opposite direction with respect to the axis, and comprising at the stem a lateral side face extending lengthwise with respect to the axis which is complementary to the lateral face of the head, the end face of the head together with its inclined sides and its lateral faces and the meeting surface describing a centrally symmetrical octagon, and the meeting surface together with the end face and lateral faces of the stem being symmetrical about the center of the stem. The head may describe a regular octagon. The stem may describe a square. But the stem may also describe a circle. The elements can be laid to form a composite ground covering structure, laid e.g. in herringbone bond pattern, and laid e.g. to include one or more supplementing slab elements of the same peripheral configuration as the stems of the elements.
Abstract:
Modular interlocking paving elements of uniform configuration are provided each in the form of a substantially right angular body bounded peripherally by two outer sides meeting at an outer angle apex, two inner sides meeting at an inner angle apex and two front sides each extending between respective ends of an inner side and an outer side, with dummy joint gaps formed in and extending across the top side of the body each from the inner angle apex to a midpoint of one of the outer sides. The inner sides, front sides, half sections of outer sides and dummy gaps are of substantially the same length, and each has longitudinal portions thereof projecting outside and/or recessed inside a straight base line between the ends thereof, so that the top side of each element appears to be composed of three four-sided elemental units disposed side by side and two or more of the elements will interlock laterally yet present the same surface appearance in any of a variety of side-by-side orientations. The projection/recess configuration preferably is constituted by oblique surface portions alternating in direction. The dummy gaps form predetermined breaking regions along which an element upon being overloaded will break preferentially, thus preserving both its top side appearance and an interlocking relationship. The elements are particularly suitable for being arranged in groups that can be lifted, transported and laid as units by mechanical laying apparatus.
Abstract:
The invention relates to a composite paving structure consisting of elements forming a pattern. The structure is made up of laying units each of which has a group of elements adjoining at their respective peripheries and held together by predetermined rupture zones. Supplementing stones are disposed at the boundaries of adjacent units. The stones have one or more elements and extend, in each case, into recesses in both of two adjacent units. Preferably, the stones are of one shape and the pattern is a herringbone pattern. The units may be offset relative to one another in the herringbone pattern.
Abstract:
A method of producing a ground covering from individual paving stones by arranging a group of individual paving stones in the form of a section of the ground covering to be produced, grasping the group by means of a lateral compressive force from two opposed sides leaving out the lower range of the paving stones in laid condition, hoisting and moving the group thus grasped to the place of laying, and depositing the group there. The vertical distribution of the compressive force is so selected that it is greater in the lower range of grasp than in the upper range of grasp.An apparatus for carrying out this method includes a laying vehicle which carries a gripping tongs, the gripping faces of which are movable at least vertically by a means of the laying vehicle and are formed by linings diverging from the bottom to the top.
Abstract:
An angular paving stone (2) for paving areas, comprising two outer sides (16), two inner sides (18) and two face sides (20). At the five outer corners (4) of the angular paving stone (2) there are provided quarter recesses (22). At the center of the outer sides (16) of the angular paving stone (2) there are provided half recesses (24). At the inner corner (6) of the angular paving stone (2) there is provided a three-quarter recess (26). The partial recesses (22, 24, 26) supplement each other in the paved area so as to form full recesses (38) for water discharge.
