ABSTRACT:
The present invention is directed to a block building system for building a wall structure that includes a plurality of pre-formed blocks configured to be stacked vertically upon one another to form the wall structure. Each block has at least one frustum-shaped protrusion on a top surface of the block, a horizontal channel formed in a bottom surface of the block, and at least one aperture extending vertically through an interior of the block. The system also has at least one base track, a plurality of T-shaped reinforcement members configured to engage with and extend upwardly from the track, a plurality of extension members that interlock with and extend T-shaped reinforcement members, and securing members. One or more courses of blocks can be vertically stacked over the base track by passing the T-shaped reinforcement members and/or extension members through the apertures formed in the blocks, thereby forming the wall structure.
