초록

이 논문에서는 콘크리트 고주탑 시공을 위한 최첨단 공법이라 할 수 있는 슬립폼 시스템 공법의 기술자립을 목적으로 슬립폼 설계기술을 연구하였다. 대상 주탑은 10m의 높이를 갖으며 보통 케이블 교량의 주탑에서 적용하는 사각 중공 형상으로 계획하였다. 슬립폼 시스템은 콘크리트의 연속 타설을 고려하여 슬립폼이 연속적으로 단면의 치수변화와 두께변화에 대응할 수 있도록 설계하였다. 또한 시공시 슬립폼에 작용하는 다양한 하중에 대한 안전성을 검토하고, BIM에 의한 가상 시공으로 실용성을 사전 검증하였다. 설계된 제작 도면을 바탕으로 슬립폼 시스템을 제작하고 10m 높이의 주탑을 성공적으로 시공함으로써 개발된 변단면 슬립폼 시스템의 효율성을 입증하는 성과를 얻을 수 있었다.

This paper studied design of slip form system considering the erection of a pylon mock-up. The height of the pylon is 10 m. A rectangular hollow cross-section was considered. The outer and inner dimensions of the pylons were varied with respect to the height. The thickness of 1 sides among the 4 faces were varied. Accordingly the slip form was designed to respond to continuous changes in its dimensions and thickness. Structural analysis was conducted to examine structural safety of the slip form. Virtual construction by BIM proved its practicality. The developed design technologies were successfully applied to the erection of a 10m high pylon executed for field verification test.
