PROBLEM TO BE SOLVED: To provide a deck truss bridge capable of having simplified constitution with few constituent members and being constituted at a low cost. SOLUTION: A bridge 1 is so constituted that a floor slab 10 is borne on a main truss 20 assembled at the lower side thereof. The floor slab 10 is so constituted that a concrete layer 12 is formed on a sill substrate 11, and the main truss 20 is so constituted that one lower chord 22 extended in the direction of the bridge axis placed to the center at right angles to the bridge axis and a longitudinal beam 21S on the bridge side of a floor framing 21 provided by connecting to the floor slab 10 on the lower surface side of the floor slab 10 are connected with a diagonal member 23. Then, when the diagonal member 23 is projected in the direction of the bridge axis of the bridge 1, it is so placed that the oblique side of a triangle making the lower chord 22 as the vertex thereof is formed. |
