PRECAST SEGMENT AND PRECAST CONCRETE STRUCTURE

摘要

PURPOSE: A precast segment and a precast concrete structure, which can improve the integral mobility of a plurality of precast segments, are provided to perform the construction of a precast concrete structure by improving the resistivity against the shearing stress of a connection region. CONSTITUTION: A precast segment and a precast concrete structure comprise a first precast segment(100) and a second precast segment(200). The second precast segment is contacted with the first precast segment to be connected. The first precast segment comprises a protruding key(110) formed on the connection area with one side section of the second precast segment in order to reinforce the connection part of the second precast segment and the first precast.
