PRECAST BOX USING BENDED ANGLE CONNECTION PLATE AND CONSTRUCTION METHOD THEREFOR

摘要

The present invention relates to a PC box using a bent angle-type connecting plate and a constructing method thereof, capable of simply integrating upper and lower PC segments after manufacturing the upper and lower PC segments and vertically stacking the upper and lower segments one after another. Connection grooves are formed on lateral surfaces of both lateral wall units of the upper and lower PC segments coming into contact with each other. Main steel reinforcements are welded and installed in the connected connection grooves (A1, A2). Finger connection plates coupled with connection bolts are exposed. Accordingly, the upper and lower PC segments are vertically joined by connecting the exposed finger connection plates to additional connection plates with nuts.
