摘要

A precast concrete l-deck is provided. The l-deck comprises a bottom slab member, or soffit, with a plurality of I-beams evenly spaced along the width of the soffit, the I-beams being parallel to each other along the length of the soffit. The l-deck has diaphragm members on either end, perpendicular to the I-beams Pre-stress wires are embedded in the soffit and I-beams between the diaphragms. The spaces between the I-beams may be used to run wiring, plumbing, or ducts, or they may be filled with a filling material. The l-deck may be used in bridging and support systems for roofing or flooring.
