Abstract
A building block includes a partially hollow cubic body, each side of which includes a square frame portion having a predetermined thickness, and a cross-shaped rib portion having a thickness twice as large as the thickness of the frame portion. The cross-shaped rib portions cooperate to divide a space behind each frame portion into four squared cavities. At least one side of the cubic body is provided at two diagonally opposite cavities with two centered round connecting posts projected from that side by a predetermined distance, and each of the round connecting posts has an outer diameter equal to a length of each side of the squared cavity. Any two laterally or diagonally disposed building blocks could be firmly connected to each other by inserting the round connecting posts of a third building block into two diagonally opposite cavities separately on the two laterally or diagonally disposed building blocks.
