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. In the second type, the thin plate is planar, and the filler material completely fills the lower half of the area between the longitudinal beam stiffener and the bottom flanges thereof, to which the planar thin plate is attached. The third type of form uses a thin plate, as well, but without filler material, the thin plate adhering to the longitudinal beam stiffeners at a position similar to the position of the valleys of the corrugations in the first type of form. |
