STEEL CONCRETE COMPOSITE FLOOR SLAB BRIDGE |
摘要 |
PROBLEM TO BE SOLVED: To provide a steel concrete composite floor slab bridge capable of limiting the height of a structure of steel concrete composite floor slab bridge low. SOLUTION: A floor slab bottom steel plate 2 is constructed and fixed on a main girder 1 extended along a bridge axis by having a floor slab span in the direction of a bridge width corresponding to a span of a reinforced concrete floor slab having a bottom steel plate. A plurality of vertical rib steel plates 3 each having a large number of composite through-holes 3a of concrete are arranged in a standing state on the floor slab bottom steel plate 2 so as to extend along the bridge axis at intervals in the direction of the bridge width. Lower ends of the vertical rib steel plates 3 are fixed to the floor slab bottom steel plate 2, and a large number of reinforced bars 4 are arranged on the vertical rib steel plates so as to extend in the direction of the bridge width. The concrete 6 is placed on the floor slab bottom steel plate 2 so as to embed the vertical rib steel plates 3 and the reinforced bars 4 and is solidified to connect to the vertical rib steel plates 3 by solidification in a large number of through-holes 3a to compose the concrete layer 6 with the floor slab bottom steel plate 2 and the main girder 1.
