Abstract:
The method of preparing stackable block structures from raw concrete mixes with the block structures having top, opposed bottom and side surfaces, said method utilizing a movable planar base support, a mold box with an open top and bottom, opposed longitudinal side panels and opposed lateral side panels with core bar receiving openings formed therein, and a reciprocating top shoe for reciprocatory up and down motion to engage the raw concrete mix so as to configure the top surface of said block structures within said mold box, and means to charge said mold box with raw concrete mix materials, said method being characterized in that:(a) said movable planar base support is a conveyor belt arranged to travel along a generally horizontal axis of motion and to support said mold box and core bars;(b) said charging means infusing said raw concrete mix materials in said mold box;(c) said core bars being reciprocably introduced and removed from said charged mold box through said core bar receiving openings and along an axis disposed parallel to the surface of said core bar and parallel to longitudinal surfaces of said core bars and parallel to and coincidentally with said conveyor belt motion axis and arranged to configure one of said two opposed side surfaces of said stackable block structure;(d) said top shoe being reciprocably introduced and removed from said charged mold box along a vertical axis perpendicular to said core bars axis of motion, and configuring the opposed side surface of said stackable block structure; and(e) the lateral side panels of said mold box being configured to form the top and bottom surfaces of a dual stackable block blank, with said dual stackable block blank being cleavable along its mid-section to form a pair of substantially identical stackable block structures.
