IMPROVED EXODERMIC DECK SYSTEM

摘要

An exodermic deck (10) for structural floors including bridge floors, road beds, pedestrian walkways, or the like, comprises a composite structure of a grid component (12) and a top component (14). The grid component (12) is preferably made of steel and includes a plurality of main bearing bars (16) and a plurality of distribution bars (18) oriented perpendicular to the main bearing bars (16). The top component (14) is preferably made from reinforced concrete. The upper portions (25) of either the main bearing bars (16) or the distribution bars (18) are embedded in the reinforced concrete component (14) permitting horizontal shear transfer and creating a composite deck structure (10) which maximizes the use of tensile strength of steel and the compressive strength of concrete. The top sections (25) of the embedded bars (16) have gripping surfaces for effecting mechanical locks between the grid component (12) and the concrete component (14) and increasing the horizontal shear transfer therebetween.
