混凝土块具有斜面开口边缘

Concrete block with beveled core opening edge
Abstract:
Methods and equipment for forming beveled edge(s) around the core opening in a concrete block are disclosed. The formation of the beveled edge(s) minimizes feathering along the block edges that are beveled as the block is stripped from a mold. Any feathering that does occur is shifted away from the bottom surface of the block to allow the block to lay flat on other blocks when dry stacked in a wall.
