Curb and safety rail system for a bridge deck

摘要

A light-weight, corrosion-resistant, readily installed bridge deck is formed of modular deck panels spliced to each other on site. Each of the deck panels is shop-fabricated by longitudinally welding flanges of adjacently placed multi-void extruded aluminum alloy structural elements. Transfer splices of longitudinally adjacent elongate elements are made by providing shear elements connecting individual elongate structural elements of each deck panel end-to-end prior to longitudinal welding of adjacent elongate elements, with the end joints between the elongate elements being arrayed in a staggered manner. A safety rail system is mounted to run alongside and above outer edges of the finished bridge deck mounted to a system of support girders.
