Abstract:
1. A construction block having a first end and a second end; each of the first end and the second end having a plurality of substantially planar bearing surfaces, at least two of the bearing surfaces being relatively disposed at an obtuse angle, wherein an engaging portion of the first end of a first block is complementary in shape to an engaging portion of the second end of a second block and whereby the first end of the block includes an outermost bearing surface furthest from the second end and an innermost bearing surface closest to the second end, both the innermost bearing surface and the outermost bearing surfaces being adjacent a periphery of the first end, the innermost bearing surface having at least two intermediate bearing surfaces, each of said at least two intermediate bearing surfaces being joined to the innermost bearing surface along an edge, the two intermediate bearing surfaces being joined to each other along an edge and being relatively disposed at an obtuse angle, each of the two intermediate bearing surfaces being disposed to the innermost bearing surface at an obtuse angle.
