Machine for manufacturing concrete u-wall type construction blocks by molding each concrete u-wall construction block from concrete poured about a block cage made from reinforcing material while said block cage is loaded within said machine

Abstract

A machine for and method of manufacturing concrete U-wall construction blocks, each having a front wall portion and a pair of stem portions extending from said front wall portion. The method involves providing a system of molding jacket panels, including a core molding assembly having a pair of inside stem jacket panels that are adjustably supportable in a substantially parallel manner during a molding process, and arranged is such a manner that the front wall portion is molded in downwardly facing direction toward a horizontal support surface and completely enclosed in one or more molding jacket panels. Before block molding operations, the thickness of the front wall portion of the U-wall construction block is set by determining the thickness of a front wall surface liner and installing the front wall surface forming liner within the system of molding jacket panels. Also, thickness of the stem portions of the U-wall construction block is set by determining the proper distance between the pair of said inside stem jacket panels supported in a parallel manner during the block molding process. Thereafter, concrete is poured or injected through pour openings provided in the molding jacket apparatus to form the front wall portion and stem portions of the concrete U-wall block.
