초록

2005년 11월 건축법 개정을 통해 리모델링이 용이한 라멘구조의 공동주택 신축 시 용적률과 층수 등의 인센티브를 부여함으로써 PC구조적용에 대한 관심이 증가하고 있다. 특히 PC구조의 기둥과 보 접합부는 구조가 복잡하다는 특성 때문에 거푸집을 설치하고 해체하는 과정이 매우 까다롭다. 현재 접합부 거푸집 설치 시 현장에서 합판 거푸집을 제작 및 설치하여 인력이 많이 소요되고, 시공성이 낮다. 또한 콘크리트 타설 후 해체된 거푸집은 파손되어 재사용이 불가능하여 건축 폐기물이 다량으로 발생한다는 문제점을 가지고 있기 때문에 이런 문제점들을 해결 할 연구가 필요한 실정이다. 그러나 국내외적으로 PC구조 접합부의 구조적 성능에 관한 연구들이 진행되어져 왔을 뿐, PC구조 접합부 거푸집에 관한 연구는 미비한 실정이다. 따라서 본 연구는 PC구조 접합부공사의 생산성 향상을 위한 거푸집개발을 목적으로 하고, 개선 거푸집 사용에 따른 기존 거푸집과의 비교를 통하여 생산성 및 경제성 향상의 기대효과를 제시한다.

With the amendment to the Building Act in November of 2005 that offered incentives in terms of floor area ratio and number of stories to apartment buildings adopting the Rahmen structure to facilitate remodeling, the construction industry is paying more attention to PC structures. As connections between PC columns and beams require complex design, it is very difficult to install and remove forms. Since forms made of plywood for such connections are fabricated and installed on site, a significant amount of labor is required, and constructability is low. Furthermore, after concrete casting, the forms are removed in a state in which they cannot be recycled, which leads to a significant amount of construction waste. For this reason, a solution to address such issues needs to be studied. However, many researchers have focused only on the structural performance of PC structures in Korea and elsewhere, ignoring the need for research on the forms used in building PC structure connections. Therefore, this research aims to develop a form that can improve the productivity of PC structure connection construction, and compare it with conventional forms to highlight its contribution to gains in productivity and economic viability.
