ABSTRACT:
A device for use in the installation of lightweight concrete roof systems includes a base element having a substantially flat portion and a wire tie. The wire tie extends from the base element and terminates at opposite ends which may be formed in a ring or loop. In use, the base element is mechanically fastened to the bar joist, through the steel deck, of the roof system. The terminal ends of the wire tie are secured to steel-welded wire reinforcement fabric overlying a layer of lightweight concrete, thereby securing the lightweight concrete to the steel deck of the roof system and preventing separation of the lightweight concrete due to external forces such as wind sheer.
