ABSTRACT:
A large motion expansion joint having a plurality of parallel load-carrying modules which are disposed transverse to the direction of the roadway. The load-carrying modules generally span the expansion gap between adjacent structural members to support vehicular traffic thereon and include a first end module mounted to an edge of one of the structural members, a second end module mounted to an edge of the other structural member and at least one intermediate module. The intermediate modules carry a plurality of spaced sleeve-like beam guides which are aligned with spaced elongated sleeve-like support beam housings secured to the second end module. A plurality of support beams are fixed to the first end module and slide into the beam guides and housings generally in the direction of the roadway so as to support the intermediate load-carrying modules. During expansion and contraction of the expansion gap, the load-carrying modules slide upon the support beams and move toward and away from each other as the gap width changes. The spacing between modules is positively proportionally maintained during expansion and contraction by linkages interconnecting each adjacent pair of load-carrying modules. Sealing means are mounted upon the load-carrying modules to provide a roadway over the gap.
