Patent ID: 7581365

Claim:
A method for securing a sheathing panel against a surface of a previously poured and cured unitary concrete wall having two outer wall surfaces and at least one wall-tie of rectangular cross-section embedded in the wall and extending therefrom to a distal wall-tie end, comprising: leaving in place the wall-ties with their extensions beyond the outer wall surface, to provide projections from the wall surface without concrete-puncturing fastener attachment; pushing the sheathing panel toward the previously-cured wall surface, thereby causing the wall-ties to penetrate through the sheathing panel such that the distal end(s) of the wall-tie(s) are exposed at the outer surface thereof, thereby to puncture and penetrate through the sheathing panel onto the previously-cured wall surface without having added mechanical fasteners to the wall surface; pressing onto the distal end(s) of each of the wall-tie(s) a press-fit sheathing-retention device which includes a tie-engagement channel portion having a channel with a substantially rectangular-cross-section of a same general shape as the rectangular cross-section of the wall-tie; and urging the tie-engagement channel portion of each sheathing-retention device along the respective wall-tie toward the previously-cured wall surface until the sheathing panel is snugly held against the wall by the press-fit sheathing-retention device(s).
