Abstract:
An arcuate structure comprised of a plurality of six-sided building block connected to each other by a plurality of recesses and projections wherein:(a). each of said building blocks is an integral building block with a substantially rhomboidal cross-sectional shape, wherein said integral building block is comprised of an outside face, an inside face, a first wall, a second wall, a third wall, and a fourth wall, and(b). said outside face opposes said inside face and is connected to said inside face by said first wall, said second wall, said third wall and said fourth wall, and(c). said first wall is comprised of a first planar projection which is substantially perpendicular to said outside wall and said inside wall, and which points inward, towards said inside wall, and(d). said first planar projection is located on said first wall at a position where a straight line drawn perpendicular to said first wall on said inside face will go through the center of said inside face, and(e). said second wall is comprised of a first receptacle with a hole to accept said first planar projection from the nearest adjacent block, and(f). said first receptacle is at a substantially acute angle to said outside wall and to said inside wall, and(g). said first receptacle is located on said second wall at a position where a straight line drawn perpendicular to said second wall on said inside face will go through the center of said inside face, and(h). said third wall is comprised of a second planar projection which is substantially perpendicular to said outside wall and said inside wall, and which points inward, towards said inside wall, and(i). said second planar projection is located on said third wall at a position where a straight line drawn perpendicular to said first wall on said inside face will go through the center of said inside face, and(j). said fourth wall is comprised of a second receptacle with a hole to accept said second planar projection from the nearest adjacent block, and(k). said second receptacle is at a substantially acute angle to said outside wall and to said inside wall, and(l). said second receptacle is located on said fourth wall at a position where a straight line drawn perpendicular to said second wall on said inside face will go through the center of said inside face, and(m). said building structure is comprised of sixty building blocks, and(n). said building structure is comprised of a trapezoidal hexecontahedron.
