A block reinforcement cage made from reinforcing material and adapted for loading within a machine during a block manufacturing process for molding a concrete U-wall construction block structure. The block cage includes an open aperture formed in each of its stem reinforcing portions. During the block manufacturing process, the first and second support members of a support mechanism are inserted within the open apertures formed in the stem reinforcing sections of the block cage, and cooperate with the open apertures of the block cage so as to (i) support the block cage when being loaded into a block manufacturing machine, (ii) define central apertures molded in each stem portion of the concrete U-wall construction block structure, and (iii) lift the molded concrete U-wall construction block when being unloaded from the machine.

A method and mold assembly for forming a dry cast concrete corner blocks having non-parallel front and rear faces and non-parallel end faces, with a hollow central core in the blocks. The corner blocks can be used to build a square or irregular corner in a retaining wall, and can be used to build columns or pillars in the wall, without having to cut the corner blocks. Fill material may be poured into aligned cores in the stacked corner blocks which form the wall corner or column, to stabilize the corner blocks.

A concrete form for holding a concrete product in place during a curing process with at least one side movable by a rotary driven power source and a actuator. A rotary power tool with a helical cutout combinable to a second adapter on the rotary driven power source to rotate the rotary driven power source to power the actuator and move the at least one side.

A form for separating a concrete block and a method for separating a concrete block from the form. The formed concrete block remains stationary while the doors of the form are pulled away from the concrete block in order to more conveniently, efficiently, and safely obtain access to the formed concrete block for its removal.

A mold extractor assembly for use with a concrete products forming machine of a type having mold mount shelves and a feed box assembly mounted behind the mold mount shelves and moveable in a vertical and horizontal direction to dispense concrete into cavities defined within a mold box mounted on the shelves. The mold extractor assembly comprises a guide rail assembly horizontally oriented along and vertically moveable with the feed box assembly. An extractor arm assembly is moveable along the guide rail assembly in a horizontal direction toward the mold mount shelves. An extractor fork assembly is telescopically nested about the extractor arm assembly and configured to extend a horizontal reach of the mold extractor assembly to beyond the mold mount shelves so that the mold box can be lifted off of the mold mount shelves via the extractor fork assembly and carried forwardly to a mold transfer assembly.

A method of forming simulated stone or brick column or a retaining wall is made up of rows of masonry blocks of generally trapezoidal configuration arranged in end-to-end relation to one another in each row, each block including a recessed portion being aligned with one another in each row and each block having textured wall surfaces simulating the appearance of brick or stone along one or more wall surfaces arranged in different configurations without the necessity of interlocking the blocks together.
