Abstract:
A light-weight deck form for prefabrication and replacement of sections of a bridge roadway comprising a slab of concrete having longitudinal reinforcement bars, and transverse reinforcement bars generally perpendicular to said longitudinal reinforcement bars, longitudinal beam stiffeners supporting said slab, each having a bottom flange and a web plate generally perpendicular to said flange, and a thin plate welded to said longitudinal beam stiffeners, and mechanical connectors for connecting said longitudinal reninforcement bars to longitudinal reinforcement bars of another deck form, each of said connectors comprising a first generally cylindrical male connector element and a second female connector element, said elements being axially aligned with each other and with respect to one of said longitudinal reinforcement bars, said second female connector element defining a generally cylindrical opening for insertion of said first generally cylindrical male connector element, for engaging said second female connector element with said first generally cylindrical male connector element by rotating said first generally cylindrical male connector element one-quarter turn, each of said first generally cylindrical male connector element and said opening defining over less than all of their surfaces a means for connecting one to the other, including multiple, less than quarter-round sections defining interlocking elements, to provide a facility for placement of said first generally cylindrical male connector element into said opening and to thereafter engage said second female connector element with said first generally cylindical male connector element, said means for connecting defined by said first generally cylindrical male connector element including V-shaped grooves, and said means for connecting defined by said opening also including V-shaped grooves.
