PIER STRUCTURE HAVING PRECAST SEGMENT

摘要

A pier structure using precast segments is provided to assemble precast segments to each other precisely by fitting projections to grooves. A pier structure using precast segments comprises a plurality of precast segment(120), a footing(130), and a coping unit(110). The footing is built on the ground. The coping unit is mounted on a top precast segment to support a slab. The segment includes a main body(121), grooves(123), and lower projections(122). The grooves are formed on the top of the main body and opened for the coping unit. The lower projection is formed at the lower part of the main body. An upper projection(125) is formed between the grooves. A support groove(124) is formed between the lower projections to be assembled to the upper projection of a lower precast segment. The footing includes a main body(131), grooves(133) formed on the main body, and an upper projection(135) formed between the grooves.
