PC PC Connection of compressed joint by post-tensioning between PC-column and PC beam and construction method thereof

摘要

The present invention relates to a post-tension compression structure system using a PC column and a segmented PC beam, and a construction method thereof. More specifically, to overcome the limitations of lifting weight and workability, the beam is segmented and produced in the longitudinal direction of the cross section. The present invention relates to a post-tension compression structure system using a PC pillar and a segmented PC beam to be integrated with a PC pillar in the construction, and a construction method thereof. One preferred embodiment of the post-tension crimping structure system using a PC column and a segmented PC beam of the present invention is a PC pillar is formed with a protruding jaw so as to protrude outward at a predetermined height and PC pillars on the upper and lower portions of the protruding jaw respectively. An upper through hole and a lower through hole formed therethrough are formed, and the PC beam is formed with a hollow portion having an upper portion opened in a predetermined section of the central portion in the longitudinal direction. The upper through hole is formed by penetrating from the upper end of the cross section of both ends of the PC beam to the hollow portion, and the lower through hole is formed by penetrating in the longitudinal direction below the cross section of the PC beam, and the center portion in the width direction of the PC beam is cut out to form the first member. And a second member, wherein the first member and the second member penetrate the upper end face of both ends of the longitudinal direction and the lower end face of the cross section at predetermined intervals in the longitudinal direction. It is formed by fitting the bearing plate to each end of the steel bar by fixing with a nut, the upper mounting hole and the lower through hole, the upper through hole and the lower through hole so that the lower mounting jaw of the PC beam is projected by the PC pillar Post-tension is introduced by inserting a tension member so as to insert the upper through hole and the lower through hole of the PC column and the upper through hole and the lower through hole of the PC beam at the same time, respectively, and the lower through hole of the PC column and the PC on both sides. It is formed by introducing a post tension by inserting a tension member to insert the upper through hole of the beam.
