Abstract

A connection assembly mechanism for coupling vertical precast structures includes a hollow box section member, and first and second wall brackets. The hollow box section member has first and second vertical members, and first and second horizontal members. A first set of elongated connectors extending from the first vertical member is embedded within a horizontal precast structure. The second vertical member is flush-mounted on a lateral side of the horizontal precast structure. A first horizontal flange of the first wall bracket is flush-mounted with a base portion of a pocket member of a first vertical precast structure and is coupled with the first horizontal member. A second horizontal flange of the second wall bracket is flush-mounted with a base portion of a second vertical precast structure and is coupled with the second horizontal member. For such couplings, at least two connection mechanisms are used at a construction site.
