Abstract:
The present document describes a padding layer for a multi-layered sports playing field. Various improvements are proposed for enhancing athlete's safety, surface hardness, water drainage, heat management, ease of assembly/installation, durability/longevity, uniformity, resistance to change in weather according to seasons, and stability. The improvements include: matching (multiple-wise) of spacing between rows of backstitches of the top layer and the drainage channels on top surface of the padding layer; a slit in the external tab portion of the padding layer panel, a slit near the lateral part of the tab or blank portion providing a hinging effect thereto, and/or protrusions at various positions on the tab or blank portions to account for change in size of the padding layer panel; drainage holes within the drainage channels; and various configurations of drainage channels on the bottom surface of the padding layer to improve evacuation of water toward the sides of the playing surface.
Abstract:
Systems and methods for a porous pavement system are described. The porous pavement system includes paver blocks designed to facilitate water seepage between the paver blocks and to permit water storage within the blocks. The paver blocks may be cabled together to create paving units that facilitate installation and maintenance of the pavement system. The porous 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 first and second sides extending radially from the first vertex; a second pair of third and fourth sides extending radially from the third vertex; a third pair of fifth and sixth sides extending radially from the fifth vertex; wherein the sides of at least one 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, and the artificial flagstone has no rotational symmetry when rotated about a central axis.
Abstract:
A paving block system is provided that includes a plurality of paving blocks arranged together to form a surface. Each paving block includes a recess located on a side surface and the paving blocks are arranged so that each recess abuts another recess so as to form drainage holes in the surface. The drainage holes have a top opening and a bottom opening and the bottom opening is larger in area than the top opening.
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:
The invention relates to a grass paver with a grid-type body which is formed by intersecting transverse portions and longitudinal portions, said portions forming at least one grid opening, wherein the transverse portions project beyond the longitudinal portions, and the longitudinal portions project beyond the transverse portions, wherein corners of the grass paver are each formed by a limb of one of the transverse portions and a limb of one of the longitudinal portions, and wherein the grass paver has a flat upper face. In this case, the longitudinal portions and the transverse portions have different heights and the lower surfaces of said portions define at least one lower contact plane and at least one upper contact plane on an underside of the grass paver.
Abstract:
The invention relates to a set of concrete pavers, comprising substantially rectangular pavers of uniform height with vertical side faces, a number of pavers of uniform or different lengths and widths being arranged in a row, and, in particular for forming a rectangular or square laying bundle that can be picked up by machine, comprising a number of parallel, adjacent rows of pavers, continuous linear joints being formed in the end-paver region of the rows of pavers when the sets are laid together or, optionally, substantially meandering joints being obtainable by interchanging row-end pavers, which are of different lengths and are in close proximity, from neighboring sets; at least one section of the upper delimiting surface of the pavers is convexly cambered towards the outside and projections on the base parts of the pavers are spaced apart on the side faces of the base parts, the projections forming support elements for the adjacent pavers and, in combination with projections on adjacent pavers, creating spaces that act as water-drainage openings in the joint regions, the pavers in each set comprising 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.
Abstract:
A paver system comprising a plurality of paver pieces and at least one substrate. Each of the paver pieces has a top surface and a bottom surface. The bottom surface of the paver pieces is configured for mating with the upper surface of the substrate, whereby paver pieces coupled to the substrate are prevented from moving laterally.
Abstract:
There has been disclosed a cast stone (1) for securing traffic areas outdoors, with the stone (1) bearing at least one pair consisting of a protrusion (9) and an adjacent recess (10) substantially matching the form of the protrusion of the adjoining laid stone (1). It is provided that the tip of the protrusion (9) and the bottom (13) of the recess (10) have an integrally moulded layer (12) of material facing away from the associated lateral face (3, 4).
Abstract:
An apparatus for the production of concrete paving stones, including an open top mold having a number of die cavities each with adjoining recesses, wherein the free volume of the recesses is reduced by local cross-sectional constrictions at the upper filling-in region of the recesses. Also included is a pressure ram for cooperation with each die cavity, the pressure ram having lateral projections each with a contour corresponding to the cross-section of the recesses at the constriction for entering into the recesses.
