Abstract:
1. A cell core for installation in a cell of a hollow cored dry stack block, the block having a block top surface and a block bottom surface, the cell being bounded on two opposing sides by respective transverse webs, each transverse web having a v-shaped or u-shaped web notch with a notch bottom, the cell core having a compressibility, and the cell core comprising: a tablet shaped body portion, the body portion having a top surface, a bottom surface, a first face surface, a second face surface, a first end surface, and a second end surface; and a pair of opposing trapezoidal shaped ear members, one ear member being integral with the first end surface and the other ear member being integral with the second end surface, each ear member having an ear base, and each ear member being dimensioned for insertion in one of the respective web notches to an inserted position and for formation of a notch gap between the ear base and the notch bottom upon insertion in the notch to accommodate crumbing which may accumulate in the web notch at or near the notch bottom during manufacturing of the block, each ear member providing for the cell core to be urged into a position in the cell providing that the core top surface is at or below the block top surface and the core bottom surface is at or above the block bottom surface when installed, providing, when the block is installed in a wall, for the block bottom surface to rest directly upon a block top surface of one or more blocks installed beneath the block in the wall and for a block bottom surface of more or more blocks installed above the block in the wall to rest directly upon the block top surface, providing for the elimination of gaps between successive courses of block, the trapezoidal shape and compressibility of the ear members accommodating dimensional variations in the web notches or variations in the inserted positions of the ear members in the web notches.
