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:
A detectable warning system for persons with disabilities. The system is in one embodiment composed of a surface covering (103) and rectangular block shapes (104). The warning system may utilize a surface texture (107) such as silicon carbide or granite to create a slip-resistant surface with compliant color contrast over the rectangular block shapes (104). This surface texture (107) can be used in or along a hazardous area on the paving or floor surface and helps a person with a physical and/or visual disability distinguish a hazardous area from a non-hazardous area. In additional embodiments, ridges (112) or elongated truncated domes (116) are used to give greater detectability in various locations.
Abstract:
A moulded brick building set is inserted in a pavement. In order to provide various laying possibilities with bricks of various sizes, the moulded bricks have on their side walls mutually adapted spacers which mesh with each other.
Abstract:
To improve the flow-off of liquids from the laying pattern and mechanical laying in a concrete paving block, the ground area of the body (1) of the block has a rectangular shape formed by three squares (2, 3, 4) of equal size, the upright side surfaces of the body (1) extend evenly transversely to the ground area and each side surface of the body (1) has at least one projecting strip-like extension (5) which can be supported in the pattern with the formation of seams on adjacent bodies (1) and form interlocks or the like with extensions (5) of adjacent bodies (1).
Abstract:
A plate-shaped, square paving stone has a flat surface and fitting strips that extend perpendicularly to the lateral surfaces of the paving stones. In order to ensure a large number of laying combinations while forming symmetrical straight joints, each lateral surface has two fitting strips. One fitting strip (4') is arranged at the diagonally opposite corners (5) between adjacent lateral surfaces (3). When the paving stone is observed from the side of its flat surface, the other fitting strip (4'') is arranged relative to the fitting strips (4') located at the two other diagonally opposite corners (6) between adjacent lateral surfaces (3) at a distance slightly larger than the length of said fitting strips (4').
Abstract:
The proposal is for a block (1) having lateral spacers (12, 13) to form uniform seams (22). The mating surfaces (4) of the spacers (12, 13) are shaped for the mating fit of an adjacent block in a row (19) of blocks in such a way that they take the same course with paired, complementary spacers (12, 13) of adjacent block sides (9, 11) that they mesh. This provides a block which, owing to the shape of its spacers, is secured against laterally parallel movement in the row (19).
Abstract:
The invention is based on a flat moulded concrete slab, especially for liquid-proof ground coverage. In dealing with substances, especially liquids, which are harmful to the ground, the intention is to prevent their further spread in the event of egress, spillage, outflow or the like. The concrete slab (10) of the invention is divided into sections (13) by dummy joints (12) in grid array. The dummy joints (12) act as drainage channels so that any liquid running out can run off via the dummy joints (12) and the surfaces of the sections (13) remain largely liquid free. This prevents the liquid from being further distributed by the passage of pedestrians or vehicles over the concrete slab (10).
Abstract:
A set of shaped bricks for paving with broad joints (50) between the bricks, in which: (a) the set of shaped bricks has first bricks (4) with a larger area in plan and second bricks (6) with a smaller area in plan; and (b) only one of the two kinds of brick (4; 6) have several integral projecting spacers (8) around their periphery to form the broad joints (50).
Abstract:
A paving element includes upper and lower surfaces and one or more drainage channels extending through the paving element between the upper and lower surfaces. The drainage channels include a substantially concave or cupule shaped upper portion, provided on the upper surface of the paving element, and a channel from the concave portion through to the lower surface of the bottom surface of the paving element. The drainage channels can be complete, when provided in the interior of the paving element, or partial, when provided along the sides or perimeter of the paving element. The partial channels are completed when the paving element is placed adjacent another paving element when forming a pavement. The drainage channels are adapted to facilitate the cleaning process of the channels.
Abstract:
A permeable surface covering unit comprises a top surface and at least two pairs of irregularly shaped mating sides, one or more passageways extending downwardly from the top surface, and at least one under channel connected to the passageways for retaining liquid, such as storm water. The sides of the unit preferably define an irregular rotational tessellation element. The passageways may comprise gaps or side cavities between units and/or core cavities or other passageways within the unit. Optional undercuts may be provided in the core cavities. Pervious material plugs are cast into the cavities extending into the channel or undercut. Thereby the plug is locked into the cavity like a rivet and resists being dislodged by mechanical or hydraulic forces. A permeable surface embodiment comprises a combination of pervious and impervious units, wherein the ratio of permeable to impermeable units and resulting surface absorption rate may be adjusted.
