Abstract:

A non-top-supported column attachment bracket assembly is provided, that includes a generally W-shaped bracket to provide a strong connection between non-top supported wood fences and masonry walls such as concrete masonry unit (CMU) walls or cast in place (CIP) walls. The W-shape provides a matrix inside the hardening structure of the wall, while simultaneously engaging the horizontal reinforcing bar of the wall. The W-anchor further includes a cover plate disposed onto the bracket. The W-shaped bracket can be installed to the upper portion of the wall just prior to grouting or during grouting, where the bracket can be pressed onto the horizontal bar before the grout has hardened. After the hardening structure is cured, fencing posts are attached to a column connection portion of the W-anchor that extends from the top of the wall.
