Abstract: PURPOSE: A pre-cast concrete floor for the end of a bridge that contains simplified construction process and construction method thereof is provided. CONSTITUTION: A construction of a pre-cast concrete floor for the end of a bridge contains the steps of: establishing a pre-cast concrete floor(1) on a mold, applying a pre-stress(2) to a throttle direction to secure an integration between floors and to improve fatigue resistance, and connecting a floor(6) of the end established on the upper part of a strut of the bridge to a pre-cast pre-stressed concrete floor by a junction. Because many shear junction materials are arranged on the end floor, a shear pocket(8) is formed to be larger than a shear pocket(11) of the pre-cast pre-stressed floor for storing the shear junction materials. Herein, a main steel reinforcing(9) over the shear pocket is exposed.

Abstract: PURPOSE: A pre-cast and pre-stressed concrete bridge floor is provided with a non-adhesive sustaining material to enable to remove and replace the pre-cast floor and to improve a junction structure. CONSTITUTION: A pre-cast concrete floor(1) includes a junction(2) between floors differently from an established floor in a work place. To secure a resistance for a vertical shear force acted on the junction between floors by the weight of a vehicle passing through a bridge, the center of a side of the pre-cast concrete floor is formed to be more recessed than the ends of upper/lower parts. Therefore, the leakage of filling material(4) is prevented in case of packing the filling material for combining the floors after adhering a sealing tape(22) at the lower side of the floor, and a shear key is formed if the filling material is filled.
