CONSTRUCTION METHOD OF FLOOR PANEL AT END PORTION OF BRIDGE USING PRE-CAST

摘要

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.
