Description

안전한 해체가 가능한 강연선 정착구조Stranded wire fixing structure that can be safely dismantled
본 발명은 포스트텐션 콘크리트 구조물의 노후화 및 리모델링 등으로 해체 작업을 실시할 때, 강연선의 절단으로 발생하는 안전사고를 방지하기 위한 안전한 해체가 가능한 강연선 정착구조에 관한 것이다.The present invention relates to a strand fixing structure capable of safe disassembly to prevent safety accidents caused by cutting of the strand when dismantling the post-tension concrete structure due to aging and remodeling.
포스트텐션 콘크리트 구조물의 노후화 및 리모델링 등으로 해체 작업을 실시 할 때, 일반적인 철근콘크리트 구조물의 해체와 유사하게 강연선을 절단하는 방법을 사용한다. When dismantling the post-tension concrete structure due to aging or remodeling, a method of cutting the strands is used similar to the dismantling of general reinforced concrete structures.
강연선은 긴장력(인장력)이 도입된 상태이므로 이를 아무런 안전장비 없이 해체할 경우 단부에서 강연선이 튀어나와 자칫 인명사고로 이어질 수 있어 주의를 요한다. Since tension (tensile force) has been introduced into the stranded wire, caution is required because if it is dismantled without any safety equipment, the stranded wire may protrude from the end and lead to a personal accident.
대한민국 등록특허 제10-1223025호(2013년01월10일) ‘코어가 선행되어 시공되는 구조물에 강연선 정착유닛을 매립시키는 방법’및 대한민국 등록특허 제10-1187845호(2012년09월26일) ‘내하체와 강연선에 가인장력을 제공한 그라운드 앵커 구조'에서는 강연선 커팅에 따른 안전사고 방지를 위한 구조를 제시하고 있지 않는다.Republic of Korea Patent Registration No. 10-1223025 (January 10, 2013)'Method of burying a stranded wire fixing unit in a structure to be constructed with a core preceded' and Korean Patent Registration No. 10-1187845 (September 26, 2012) In the'Ground Anchor Structure that Provides Temporary Tension to the Undercarriage and Stranded Wire', a structure to prevent safety accidents caused by cutting the strands is not suggested.
