摘要:
The present invention is directed to a precast girder that is used as the outer-most lateral girder in a bridge superstructure. In one embodiment, the girder is comprised of a first flange, a second flange that is separated from the first flange, and a web that connects the first flange to the second flange so that the resulting combination of the first flange, second flange, and web generally has an I-beam cross-section. The girder further includes an edge portion that is connected to the second flange and extends away from the first and second flanges.

A modular plastic structural composite comprises a web section disposed along a horizontal axis and at least one flange section disposed along a horizontal axis parallel thereto and integrally molded to engage the top or bottom surface of said web section, wherein said composite is formed from a co-continuous immiscible polymer blend of a high density polyolefin and a thermoplastic-coated fiber material. The modular plastic composite may for example be an I-Beam, a C-Beam or a T-Beam. In one application it may be used in a bridge constructed from I-Beams, comprising a plurality of pier-supported parallel rows of larger first I-Beams, and a plurality of smaller second I-beams disposed parallel to one another and fastened perpendicular to and between adjacent rows of the larger first I-Beams, wherein the top and bottom surfaces of the second I-Beam flanges are dimensioned to nest within the opening defined by the top and bottom flanges of the first I-Beams.

Prefabricated girder element comprising two spaced‑apart flat flanges connected by a vertical web made of a rectangular flat sheet, so as to configure an I‑section girder, said web having two opposite lateral faces to which are attached a plurality of transverse flats extending vertically over the entire height of the web, distributed over the entire length of the module, and separated from one another by a constant spacing corresponding to a sub‑multiple of this length, said flats each forming a stiffening rib having one vertical side welded to the web and two spaced‑apart horizontal sides welded to the mutually‑facing internal faces of the two flanges. Said element is designed to form an element that forms part of a metal bridge span. The invention also relates to a metal bridge span and to a method for the modular construction of such a span.
