This invention relates to a process for the lifting of a dual concrete panel composite truss and especially to the process of lifting of a composite truss having a pair of spaced apart prestressed concrete panels. A lifting assembly can be rolled on the surface of a generally flat concrete panel to position a plurality of sling hooks for connection to a plurality of said lifting eye members on the generally flat concrete panel for lifting the concrete panel.

This invention relates to the lifting of a concrete panel and especially to a composite truss having a pair of spaced apart prestressed concrete panels and having a plurality of built-in lifting eye members in the end portion of one concrete panel positioned for lifting the composite truss. The lifting eyes are integrated into the composite truss to have the strength to support the two concrete panel truss during the lifting thereof without damage to the concrete panels.

This invention relates to the lifting of a concrete panel and especially to a method and apparatus for lifting a concrete panel and to lifting a composite truss having a pair of spaced apart prestressed concrete panels.
A truss lifting process and apparatus for coupling a lifting truss to a load to be lifted especially for lifting a large prefabricated concrete panel in the making of a dual panel truss having a pair of spaced apart concrete panels. A lifting truss has a plurality of spaced hydraulic cylinders hanging therefrom with each hydraulic cylinder having a grappling hook attached thereto for attaching to an attachment member on an object to be lifted. The plurality of hydraulic cylinders are actuated simultaneously to pull each coupled grappling hook and attachment member taut and then locked for the lifting truss to lift the attached object.

This invention relates to a method of making a dual panel composite truss having a pair of spaced apart prestressed concrete panels. The process includes assembling a truss frame, which includes connecting a plurality of steel posts and bent rod truss members and reinforcing rods and lifting and placing the assembled truss frame in a panel form for pouring a first prestressed concrete panel on one side of the truss frame. The truss frame with the first concrete panel is then stripped, lifted and placed on a turntable and turned to place the other side of the truss frame in the panel form for pouring a second concrete panel, to form a dual panel composite truss having parallel spaced prestressed concrete panels.
This invention relates to a dual panel composite truss having a pair of spaced apart prestressed concrete panels having a versatile and adaptive structurally supporting end bearing truss on the ends thereof. The end bearing truss incorporates a versatile and adaptive structural support on each end of the composite truss. The end bearing truss is formed as an integral part of the composite truss for supporting the ends of the composite truss when the composite truss is used for the floors or ceiling of a building. The end bearing truss advantageously forms each end of each concrete panel form for the concrete pour when making each concrete panel.

A composite truss includes a pair of spaced apart concrete panels and a plurality of substantially vertical members spanning between the pair of spaced apart concrete panels, a first end portion of each vertical member embedded in one of the pair, and a second end portion of each vertical member embedded in an opposite one of the pair. The truss also includes a diagonal member spanning between the first end of a first vertical member and the second end of a second vertical member linearly adjacent to the first vertical member and non-structurally engaging the first end portion of the first vertical member and the second end portion of the second vertical member during an assembly of the truss. The diagonal member also includes a first development length portion embedded in the first concrete panel and a second development length portion embedded in the second concrete panel.
