The hems also reinforce the panels. Each modular floor panel may have a complete hem at one end and a half hem or flange at the other end such that the panels can be readily aligned and interlocked end-to-end by inserting the half hem or flange of one panel into the full hem of a succeeding panel. A transverse clip may be used to hold together two abutted modular floor panels end-to-end and for reinforcing purposes where high floor loads are contemplated. Adjacent panels are abutted together along the sides and are held together by fitting the side lips into rails or support beams. These rails in turn are resiliently gripped in notches cut into the top edges of the side walls of V-shaped posts. The beam can be fit into these posts and resiliently held by the legs of the post, as when the post is squeezed and then released.Other References
