Abstract:
Provided is a composite panel structure comprising primary girder panels (12), intermediate panels (14), and a concrete slab (16). The primary girder panels (12) have first transverse ribs (15A). The intermediate panels (14) have second transverse ribs (15B). A plurality of the second transverse ribs (15B) are arranged in a bridge axis direction (X) with an interval on the upper surface of a second bottom steel plate (13). The second transverse ribs (15B) are arranged shiftedly in the bridge axis direction (X), to the first transverse ribs (15A). The second transverse ribs (15B) protrude from an edge of the second bottom steel plate (13) in a direction (Y) perpendicular to the bridge axis direction toward the upper surface of a first bottom steel plate (11). A plurality of through-holes (18) that penetrate in the bridge axis direction (X) and are arranged with an interval in the direction (Y) perpendicular to the bridge axis direction are formed in each of the first transverse ribs (15A) and the second transverse ribs (15B).
