US 4,709,435 A · Bridge deck system

Abstract

A system for attaching a bridge deck panel to a bridge structure which allows the panel to expand in lengthwise and sidewise directions independent of a bridge deck support structure. Brackets attached to members of a bridge deck support structure have undercuts on opposing ends which accommodate flanges on the bridge deck panel. Portions of the bracket overlying the undercut and flange prevent the deck panel from being separated from the deck support structure, but do not prevent the deck panel from lengthwise movement independent of the bridge structure due to temperature changes. To enable the panel to move in a sidewise direction, a space is provided between the outermost edge of the deck panel flange and the length of the undercut.
