There are many different ways to design the connection for a precast panel system.
Very broadly, the floor slabs and the panels both contain steel components (clips, studs, angles, etc) embedded in the concrete and linked to any reinforcing steel. The facade panel is lifted into place with a crane and the steel components are used to fasten the panel mechanically to the slab edges, using nuts and bolts. This is a relatively quick, temporary connection.
Later, the panels are adjusted and aligned, and the steel components are welded together for a permanent, inflexible connection. Panel seams are filled with some very expensive caulk that is color-matched to the panels, and windows/doors are installed in the openings to create a watertight envelope.
