PRECAST BOX USING FINGER CONNECTION PLATE AND CONSTRUCTION METHOD THEREFOR

摘要

The present invention relates to a precast concrete (PC) box using a finger connection plate, capable of individually prefabricating an upper PC segment and a lower PC segment and simply integrating the upper PC segment and the lower PC segment after vertically laminating the upper and lower PC segments, and a construction method for the same. A connection groove is connected to lower and upper connection surfaces in both side wall units of the upper and lower PC segments, and a main reinforcing bar is installed by being welded in the connected connection groove (A1, A2). The finger connection plate to which a connection bolt is coupled is exposed, and the exposed finger connection plate is connected to an overlapping connection plate by a nut so that the upper and lower PC segments are vertically connected.
