FOLDABLE CONSTRUCTION BLOCK

摘要

A construction block foldable from a flat sheet of material to form a container which may be filled with available solid material and stacked with other such blocks in staggered courses. Interlock tabs project from the center of one horizontal wall of the block and the other horizontal wall is provided with a lateral, central slot arranged to receive interlock tabs from other such blocks. The block may be folded to provide either, two symmetrical lateral interlock tabs for making lateral wall runs, or to provide lateral and transverse tabs for wall corners.
