Title:
ARCUATE STRUCTURE USING PRECAST CONCRETE SEGMENT HAVING LOOP JOINT
Document Type and Number:
Japanese Patent JP3825769
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an arcuate structure capable of reducing the cast-in place concrete volume of a connection part and improving the quality.
SOLUTION: In an arcuate structure using a precast concrete segment, precast concrete segments 1 having many loop joints at the end in the peripheral direction along the arch are arranged to form an arch in series, and mutual loop joints of serially adjacent precast concrete segments 1 are disposed so as to be superimposed and reinforcing rods are arranged in the loop joints, cast-in-place concrete 16 is placed to embed the loop joints and the reinforcing rods to construct the arcuate structure using precast concrete segment having loop joints by which serially adjacent precast concrete segments 1 are jointed mutually.
