Method and arrangement for coupling a foundation structure and a vertical precast structure

Abstract

A connection assembly mechanism includes a threaded connector, a hollow box section member, a set of elongated connectors, and a connection mechanism. The threaded connector is embedded in a foundation structure. The hollow box section member having a base including a threaded cavity receives the threaded connector and is flush mounted with an internal bottom edge of a vertical precast structure. The set of elongated connectors, positioned at opposite vertical sides of the hollow box section member, is embedded within the vertical precast structure. The connection mechanism coupling the hollow box section member and the threaded connector, thereby couples the vertical precast structure and the foundation structure.
