PROBLEM TO BE SOLVED: To provide a slab bridge using square steel tubes which is simple in structure and easy in construction, and can improve earthquake resistance.SOLUTION: A slab bridge 1 is installed with a slab 3 formed by laying a plurality of square steel tubes 8 side by side on bridge piers 2, inserting horizontal beam steel tubes 10 into the side surfaces of the square steel tubes 8 to integrate them. Partition plates 12 are installed on both sides of the horizontal beam steel tube 10 to form a division inside the square steel tube 8. The upper part of an anchor bolt 17 fixed to a bridge abutment 6 of the bridge pier 2 is inserted into the division of the square steel tube 8, and the inside of the division is filled with concrete to embed the upper part of the anchor bolt 17. The bridge pier 2 and the slab 3 are rigidly connected by the anchor bolt 17. |
