Arcuate and curvilinear assemblies comprising tandemly arranged building blocks having degrees of rotation

Claim 1

A wall assembly comprising a plurality of repeating building blocks successively arranged in a tandem array within a row, said wall assembly comprising a number of rows, each stacked one above another, said tandem arrays within each row facing in an opposite direction with respect to an adjacent row stacked above and below thereto, for the purpose of enhancing lateral forces such as those produced during an earthquake, each building block of said array being generally rectilinear with the exception of two oppositely disposed distal end walls having arcuate, circumferential male and female mating surfaces, respectively, each arcuate, circumferential male and female mating surface having a radial diameter almost equal to a width of said block to further enhance resistance to said lateral forces, each end wall being rotatively engageable with an arcuate mating end wall of an adjacent block of said assembly at any desired angle of rotation within a limited range of arc defined by circumferential end abutments terminating said arcuate mating surfaces of said mating end walls, each male end wall having means defining a hole for receiving vertical reinforcement, each hole being in registry with a hole of a block of an adjacent row stacked above and below thereto, said vertical reinforcement still further enhancing said wall assembly to resist lateral earthquake forces.
