Abstract: The disclosure sets forth pre-fabricated deck forms and reinforcement bar connectors for light-weight concrete decks on bridges. The three different types of deck forms disclosed provide light-weight and composite concrete decks for bridges, with reinforcement bars, longitudinal beam stiffeners and thin plates, and the longitudinal beam stiffeners, welded to the thin plates. The thin plates are attached to the bottom flanges of the longitudinal beam stiffeners for the first two types, and to the web plates of those stiffeners, for the third type. The bottom portion of the first two types of deck forms disclosed are filled with filler material, such as styrofoam or similar non-metallic material. In one type, the filler material is provided under the concrete slab only proximate the longitudinal beam stiffeners, and the thin plate is corrugated.
