Support product
A support product configured to receive poured concrete, the support product comprising a latticework of walls and a plurality of edges, wherein the walls extend between a lower surface and an upper surface and define a plurality of cells, wherein at least one edge comprises a catch and a partial keyway, wherein the catch is configured to connect with a catch of an adjacent support product to restrain relative movement of connected support products, and wherein the partial keyway is configured to be located adjacent to a partial keyway of a connected support product, so that adjacent partial keyways define a complete keyway between connected support products.
1. A support product for receiving a fill material in construction of a path, the support product comprising:
a plurality of walls, at least some of the plurality of walls defining cells, the plurality of walls comprising:
an edge wall defining an edge plane that is parallel to the edge wall; and
a plurality of partial keyway walls defining a partial keyway, the plurality of partial keyway walls comprising:
a pair of offset partial keyway walls that extend parallel to a first direction that is transverse to the edge plane, the pair of offset partial keyway walls comprising:
a first partial keyway wall; and
a second partial keyway wall; and
a transverse partial keyway wall extending from one of the pair of offset partial keyway walls to the other of the pair of offset partial keyway walls;
wherein:
the first partial keyway wall meets the edge wall at a first junction;
the first partial keyway wall and the edge wall define an acute angle at the first junction; and
the support product is configured to be aligned with a second support product such that the partial keyway and a second partial keyway of the second support product form a keyway configured to receive a key.
2. The support product of claim 1 , wherein the support product is part of a path.
3. The support product of claim 1 , wherein the first partial keyway wall and the transverse partial keyway wall define an acute angle therebetween.
4. The support product of claim 1 , wherein the transverse partial keyway wall and the second partial keyway wall define an obtuse angle therebetween.
5. The support product of claim 1 , wherein the second partial keyway wall is longer than the first partial keyway wall.
6. The support product of claim 1 , wherein the partial keyway defines a re-entrant corner of the support product.
7. The support product of claim 1 , further comprising a male catch that projects outwardly, the male catch comprising:
an outer catch portion of a first width; and
an inner catch portion of a second width;
wherein the first width is greater than the second width.
8. The support product of claim 1 , further comprising a female catch in the form of a groove in one of the walls of the plurality of walls.
9. The support product of claim 1 , wherein the support product comprises:
opposed major faces comprising a first major face and a second major face; and
a plurality of edge regions;
wherein each edge region comprises a respective minor face of the support product and one of the edge regions comprises the partial keyway.
10. The support product of claim 1 , further comprising a polymer.
11. The support product of claim 1 , wherein:
the first partial keyway wall extends from the first junction to a second junction, the second junction being a junction between the first partial keyway wall and the transverse partial keyway wall; and
the second partial keyway wall extends from a third junction to a wall end portion, the third junction being a junction between the transverse partial keyway wall and the second partial keyway wall;
wherein a keyway opening is defined between the first junction and the wall end portion.
12. The support product of claim 11 , wherein the wall end portion is a junction between the second partial keyway wall and another edge wall.
13. The support product of claim 1 , wherein the plurality of walls defines a cell structure, the cell structure being repeated throughout at least part of the support product;
wherein:
each wall of the plurality of walls meets another wall of the plurality of walls at a junction; and
a perimeter profile of the cell structure determined by connecting junctions with straight lines forms an asymmetric polygon.
14. The support product of claim 13 , wherein each instance of the cell structure shares at least one wall in common with another instance of the cell structure.
15. The support product of claim 1 , further comprising an access cell that is configured to enable access beneath the support product.
16. The support product of claim 15 , wherein a junction between a number of the walls of the plurality of walls comprises the access cell.
17. The support product of claim 15 , wherein a cross-sectional profile of the access cell is circular.
18. The support product of claim 15 , wherein the access cell comprises inwardly projecting projections.
19. The support product of claim 1 , wherein the support product is part of a pavement course.
20. The support product of claim 19 , wherein the pavement course further comprises a fill material, wherein:
the cells contain the fill material; and the fill material comprises one or more of:
a cementitious material;
a bituminous material; and
a granular fill material.
