Abstract:
A surface covering unit includes at least one face comprised of at least one primary rotational tessellation element. The rotational tessellation element includes at least two pairs of sides, and the sides in each pair of sides have the same length and are images of one another. The sides of a first pair of sides extend from a first vertex and are rotationally spaced from each other, and the sides of a second pair of sides extend from a second vertex and are rotationally spaced from each other. The sides of the first and second pairs of sides have two or more straight line segments or complex curves, and are not a single straight line or a single curve. One pair of sides has a length different from the other pair of sides. The surface covering has a natural appearance such that a repeating pattern is not readily apparent.
Abstract:
A method for manufacturing an actively heatable paved surface by a heating system is provided, where the paved surface includes block-like paving stones arranged in a plane and each having one or more recesses. One or more heating elements are laid out on a paving bed in a longitudinal direction in such a way that segments of the heating element(s) are oriented substantially parallel to one another with a first spacing. The first spacing correlates with a spacing of the recesses, and the laid-out heating elements are fixed on the paving bed with one or more paving stones with their bottom profiling being aligned with the laid-out heating elements in such a way that the segments or heating elements are covered over by recesses of the paving stones. The paving bed is covered with further paving stones.
Abstract:
A concrete casted paving stone of rectangular shape is described and has two pairs of opposed parallel side walls. In a first of the two pairs of side walls, an engaging projection is formed in one side wall and a through slot in the other side wall for receiving the stone-engaging projection of another paving stone therein. The second pair of opposed parallel side walls each have a slot and a further stone-engaging projection in a section thereof. The stone-engaging projections of the second pair of side walls are disposed adjacent the side wall of the first pair which contains the slot and the slot extends through the rear wall of these stone-engaging projections. The paving stone may be used as a permeable paving stone wherein to evacuate water from an upper surface of a paved surface into the underlying support bed.
Abstract:
A method for installing a paver system includes positioning a first grid substrate adjacent to a second grid substrate. The first grid substrate and the second grid substrate are flexibly bridged with a first paver piece. A first portion of the first paver piece is movably coupled with the first grid substrate at a first joint, and a second portion of the first paver piece is movably coupled with the second grid substrate at a second joint, the first and second grid substrates and the first paver piece forming an articulated paver linkage. A second paver piece is coupled with the second grid substrate. A third paver piece is coupled with the first grid substrate. The articulated paver linkage is fit within the specified area by movement of at least one of the first, second and third paver pieces and the first and second grid substrates. The movement is transmitted along the articulated paver linkage to maintain a specified alignment and spacing of the first, second and third paver pieces.
Abstract:
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 paving block is provided that includes a top surface, a bottom surface and a side surface extending between the top surface and the bottom surface. The side surface includes a recess extending from the top surface to the bottom surface, wherein the recess has a top opening in the top surface and a bottom opening in the bottom surface, wherein the bottom opening is larger in area than the top opening. The side surface also has at least a portion that extends inwardly into the paving block. In some cases, the side surface comprises an upper side surface section and a lower side surface section, wherein the lower side surface section extends inwardly into the paving block.
Abstract:
Systems and methods for a permeable pavement system are described. The permeable pavement system includes blocks designed to facilitate water seepage between the blocks and to permit water storage within the blocks. The blocks may be cabled together to create paving units that facilitate installation and maintenance of the pavement system. The permeable pavement system provides improved management of stormwater, reducing runoff and facilitating infiltration of stormwater into the subgrade below the paving system.
Abstract:
An artificial flagstone for use in combination with other similar flagstones for covering a surface with a natural random look, the flagstone having a generally hexagonal body comprising a first, second, third, fourth, fifth and sixth consecutive vertices; a first pair of generally congruent irregularly-shaped first and second sides extending radially from the first vertex and being rotationally spaced from each other by an angle α of approximately 120°; a second pair of generally congruent irregularly shaped third and fourth sides extending radially from the third vertex and being rotationally spaced from each other by an angle β of approximately 120°; a third pair of generally congruent irregularly shaped fifth and sixth sides extending radially from the fifth vertex and being rotationally spaced from each other by an angle ω of approximately 120°; wherein the sides of each of the first, second and third pair of sides have at least one split deviation along their length and are respectively rotational images of each other, whereby in use in combination with other flagstones, each one of the sides is matingly engageable with the sides of an equivalent pair of sides of a neighbouring flagstone.
Abstract:
An irregular, tessellated building unit comprises x primary elements, wherein x is an integer equal to or greater than 1. The primary element is a rotational tessellation having a plural pairs of sides extending in a generally radial direction from plural vertices, respectively. In each pair, the two sides are rotationally spaced by an angle that is divided evenly into 360 degrees. Preferably, all of the sides are irregularly shaped, but one or more sides could be wholly or partially straight. Optionally, spacers are provided on the sides of each unit. A wide variety of units may be constructed having different numbers and arrangements of primary elements. As all the units are combinations of primary elements, they readily mate with each other. A surface covering comprises a multiplicity of units assembled to form a continuous surface without overlap between units and without substantial gaps between units. A structure, such as a wall or column can be formed of building units of the invention. Because of the irregular side configurations, and different sizes and shapes of individual units, the resulting surface or structure has a natural, non-repeating pattern appearance. Optionally, minor surface and edges variations are made from unit to unit to further enhance the natural appearance of the surface covering or structure.
Abstract:
A set of concrete pavers is formed by a plurality of pavers being arranged in a paver row, and a plurality of paver rows being arranged to form a row. A number of parallel, adjacent rows form linear or meandering joints in the end-paver region of the rows when the rows are laid together. At least one section of the upper delimiting surface of the pavers is convexly cambered towards the outside, and projections on the side faces of the pavers form support elements for the adjacent pavers. The support elements, in combination with projections on adjacent pavers, create spaces that act as water-drainage openings in the joint regions. The pavers in each set include not only paving blocks with a length-to-height ratio of less than or equal to 4 but also at least one paving slab with a length-to-height ratio greater than 4.
