Definitions

  • the invention relates to a grid structure, and in particular, a grid structure for stabilising and/or supporting grass and/or soil.
  • Grid structures have previously been used for supporting or stabilising soil or grass by being imbedded in the soil or grass.
  • the grid structure has an array of open cell structures which are interconnected.
  • the grid supports soil and/or grass located within the cells and around the cells .
  • Grid structures are normally formed into modules which may be coupled to each other to form an extended grid structure which can cover an infinitely large area.
  • conventional grid structures have the disadvantage that during transportation there is a substantial amount of wasted space which is normally the space within each cell and the space surrounding the cell between one cell and adjacent cells.
  • a grid structure comprises a number of cells, each cell being spaced apart from and connected to a number of nearest adjacent cells, and the centres of the cells defining a first array of points; the cells defining a number of openings, the size of the openings being greater than the cell size, and the centres of the openings defining a second array of points; and, the spacing of the points of the second array being substantially identical to the spacing of the points of the first array.
  • a grid structure comprises a number of cells, each cell being spaced apart from and connected to a number of nearest adjacent cells; the cells defing a number of openings, the size and distribution of the openings being such that cells of a like grid structure may be inserted into the openings.
  • the cells may be arranged in a rectangular grid structure with the centers of the nearest adjacent cells defining a square with a side length greater than twice the width of a cell.
  • the nearest adjacent cells are diagonally adjacent cells and the spacing between the centre of one cell and the centre of each of the next nearest adjacent cells is greater than the width of one cell.
  • a grid structure comprises an array of cells, peripheral cells in the array comprising coupling means to permit the grid structure to be coupled to a like grid structure, the coupling means comprising a first coupling member on a peripheral cell of the grid structure and a second coupling member on a peripheral cell of the like grid structure, the first and second coupling members being adapted to engage with each other, at least partially within one of the peripheral cells, to couple the grid structure to the like grid structure.
  • the first coupling member comprises a male section and the second coupling member comprises an aperture within and adjacent to the cell wall of the peripheral cell, the male section engaging with the aperture.
  • the third aspect may be combined with the first and/or second aspects in the grid structure.
  • the cells have a substantially square cross- section.
  • cells having other cross-sections could be used, such as circular, hexagonal or other polygonal shapes.
  • each cell is diagonally connected to four adjacent cells.
  • Figure 1 is a perspective view of a grid structure
  • Figure 2 is a top view of the grid structure
  • Figure 3 is a bottom view of the grid structure
  • Figure 4 shows two grid structures nested together
  • Figure 5 is a perspective view from above of a non- peripheral cell in the grid structure shown in Figures 1 to 3;
  • Figure 6 is a perspective view from above of a male peripheral corner cell in the grid structure shown in Figures 1 to 3;
  • Figure 7 is a perspective view from below of the male peripheral corner cell shown in Figure 6;
  • Figure 8 is a perspective view from above of a female peripheral corner cell in the grid structure shown in Figures 1 to 3 ; and
  • Figure 9 is a perspective view from below of the female peripheral corner cell shown in Figure 8.
  • Figures 1 to 3 show a grid structure 1 which comprises an array of cells 2, 3, 4 diagonally interconnected by cross struts 5.
  • the grid structure 1 has three types of cell 5 structure, non-peripheral cells 4 which are each connected by cross struts 5 to four adjacent cells and two types of peripheral cells 2, 3.
  • the two types of peripheral cells 2, 3 are a male peripheral cell 3 which includes male coupling members 6 and a female peripheral cell 2 which includes female coupling members 7.
  • the grid structure 1 also includes a male peripheral corner cell 3a and a female peripheral corner cell 2a.
  • the peripheral corner cells 2a, 3a have three female and three male coupling members 7, 6 respectively.
  • the other peripheral cells 2, 3 each have two female and male coupling members 7, 6 respectively.
  • the peripheral corner cells 2a, 3a are each connected to two peripheral cells 2, 3 by connecting members 8 which increase the rigidity of the connection of the corner members 2a, 3a to the grid structure 1.
  • Each of the cells 2a, 3a, 4 are shown in more detail in Figs. 5 to 8.
  • Each of the cells 2a, 3a, 4 and the peripheral non- corner cells 2, 3 have a generally square cross-sectional area and are defined by upstanding side walls 9 with curved corner walls 11. The upper edges of the side walls 9 are castellated so that a central section 10 of each side wall 9 is lower than the height of the corner walls 11.
  • the lower central section 10 has the advantage that when the grid structure 1 is used to support grass, for example, in a 6 car park area or an area where traffic passes over the grid structure 1, the grass may enter into the lower region 10. If the lower region 10 is not present, the grass would tend to be severed by the edges of the cell walls 9 when vehicles pass over the cells 2, 2a, 3, 3a, 4.
  • the non-peripheral cell 4 (see Fig. 5) has a cross strut 5 extending from each corner wall 5.
  • the struts 5 also extend into the cell itself and meet at a central point 14.
  • the male peripheral corner cell 3a is shown in more detail in Figures 8 and 9, and is similar to the non-peripheral cell 4, except that three of the cross-struts 5 are replaced by male coupling members 6.
  • Each male coupling member 6 comprises an elongate section 17 extending from a corner wall 11 and terminates in a pin section 15.
  • the male peripheral cells 3 are similar to the male peripheral corner cell 3a, except that there are only two male coupling members 6 on adjacent corner walls 11 (see Figure 2) .
  • the female peripheral corner cell 2a is shown in more detail in Figures 6 and 7, and is similar to the non-peripheral cells 4, except that three of the cross-struts 5 are replaced by female coupling members 6.
  • Each female coupling member 6 comprises an elongate recessed section 19 , which has a recess 18, and an aperture 16 located within and adjacent to a respective corner wall 11.
  • the female peripheral cells 2 are similar to the female peripheral corner cell 2a, except 7 that there are only two female coupling members 6 on adjacent corner walls 11 (see Figure 2) .
  • each non-peripheral cell 4 is at a center of a square, the sides of which are defined by the centers of the four nearest adjacent cells.
  • the diagonal dimension of each cell is less than half the length of the diagonal of the square defined by the center points of the four nearest adjacent cells.
  • the opening defined by four immediately adjacent cells is bigger than the cross- sectional area of one cell.
  • a number of grid structures 1 can be interconnected 8 to each other to form an extended grid structure by coupling male peripheral cells 3 , 6 on one grid structure 1 to female peripheral cells 2 on another grid structure 1.
  • a male coupling member 6 engages with a female coupling member 7 by the pin section 15 engaging with the aperture 16 in the female coupling member 7 and the elongate section 17 engaging with the recess 18 in the elongate recessed section 19.
  • the invention has the advantage that it permits a more rigid connection of grid structure 1 to each other and also reduces the volume required for storage and transportation of the grid structure 1.

Abstract

Structure de grillage (1) comprenant plusieurs alvéoles (2, 3, 4), chaque alvéole non périphérique (4) étant éloignée de plusieurs des alvéoles contiguës les plus proches (2, 3, 4) et accouplée à ces alvéoles, les centres de ces alvéoles (2, 3, 4) définissant un premier groupe de points. Les alvéoles (2, 3, 4) définissent plusieurs ouvertures et la dimension de ces ouvertures est supérieure à la dimension des alvéoles (2, 3, 4). Les centres des ouvertures définissent un deuxième groupe de points. L'espacement des points du deuxième groupe est sensiblement identique à l'espacement des points du premier groupe. De plus, les alvéoles périphériques (2, 3) du groupe comprennent des moyens d'accouplement (6, 7) permettant d'accoupler la structure de grillage (1) à une structure de grillage semblable (1a). Ces moyens d'accouplement (6, 7) présentent un premier élément d'accouplement (6) sur une alvéole périphérique (3) de la structure de grillage (1) et un deuxième élément d'accouplement (7) sur une alvéole périphérique de la structure de grillage semblable. Ces premier et deuxième éléments d'accouplement (6, 7) sont conçus pour s'accoupler l'un à l'autre, au moins partiellement à l'intérieur d'une des alvéoles périphériques (2, 3), de manière à accoupler la structure de grillage (1) à la structure de grillage semblable (1a).
