发明名称 Interlocking slab element and ground surface cover
摘要 A integrally molded paving stone or slab element of ceramic material, and a ground cover made up of repeatable patterns of such elements wherein the slab elements include a hexagonal section having two 90 DEG and four 135 DEG angles and lateral and longitudinal sides and a square section with a side adjoining a side of the hexagon which is adjacent one of the 90 DEG angles. The lateral sides of the hexagon adjacent the 90 DEG angles and the sides of the square are from 3.5'' to 5'', approximately and the longitudinal sides of the hexagon section are such that there are approximately 9'' to 11'' from one 90 DEG angle to the other. Such a paving stone provides superior support for standard dual wheel truck loads when assembled in a ground cover.
