Bridge assembly and method

摘要

A bridge assembly includes a plurality of platform members which may be secured to support beams via individual platform chassis which are configured to allow tool-less attachment bolt heads thereto. A plurality of specially configured clamps are attached to the free ends of the bolts and the clamps are used to secure the platform members to the platform chassis. The platform chassis are each secured to the outer support beams via L-brackets that are mounted between the chassis and support beams. The support beams include flanged channels wherein the heads of a plurality of bolts may be attached without the need for tools. The platform members may be laid in either a parallel or perpendicular orientation with respect to the outer support beams with two different clamp styles being used depending on the orientation selected.
