PRECAST CONCRETE ARCH STRUCTURE USING LATERALLY SEGMENTED ARCH MEMBERS AND CONSTRUCTION METHOD THEREOF

摘要

The present invention relates to a precast concrete arch structure using laterally segmented arch members and a construction method thereof, wherein segment unit arch members to pre-manufacture the unit arch members, perform primary dry strong joining on joint connections of segmented members without concrete deposition to manufacture unit arch members, and lift the unit arch members to continuously arrange the unit arch members in a longitudinal direction to finish an arch structure. According to an embodiment of the present invention, the precast concrete arch structure using laterally segmented arch members comprises: a unit arch member formed by strongly joining a first segment member and a second segment member including a segment body of a segmented arch shape, and a steel joining member consisting of an upper plate, a lower plate, and a vertical plate vertically connecting the upper plate and the lower plate to have an H-shaped cross section and being embedded to protrude from one end of the segment body by a prescribed length by a joining plate to be continuously arranged on a foundation unit in a longitudinal direction; a reinforcing bar longitudinally arranged on a joint connection between the steel joining members of longitudinally continuous unit arch members; and concrete deposited and cured on the joint connection between the steel joining members of the unit arch members to perform strong wet joining.;COPYRIGHT KIPO 2020
