International Classification:

E04B 1/92

E04C 1/39

Abstract:

A radiation shielding block for constructing structural walls having flat opposed front and rear surfaces defining a thickness of the block, continuously curved, sinusoidal opposed left and right surfaces and top and bottom surfaces. The continuously curved, sinusoidal surfaces have a regular repeating wavelength pattern having a wave direction that is perpendicular to the flat front and rear surfaces, and a length that is two complete wavelengths of a sinusoidal wave. A plurality of the radiation shielding blocks are stackable in a staggered wythe construction having a plurality of wythes and at least one successive course of blocks set atop a previous course of blocks such that the continuously curved, sinusoidal surfaces of the successive course of blocks engage complementary continuously curved, sinusoidal surfaces of the previous course of blocks, and the successive course of blocks is offset by one wavelength from the previous course in a front-rear direction.
