Partial Depth Precast Concrete Deck Panels

The partial depth precast concrete deck panels system involves first placing a layer of deck panels on the steel superstructure and then pouring the remainder of the reinforced concrete deck at a later time.

This method prevents the need for as much formwork (usually, the most time-consuming part of concrete deck placement) as a cast-in-place concrete deck.

Partial depth precast deck panels are used as an alternative to cast-in-place concrete decks. They provide a driving surface for traffic.

The panels are connected to one another when the rest of the deck panel depth is being poured. To connect the panels to the steel framing, welded stud shear connectors are used in the gap between adjacent panels.

With the lower portion of the deck being precast, forming is not required in setting up for the deck system. This system is similar to the partially filled grid deck.
