[산업상의 이용분야][Industrial use]
본 발명은 콘크리트 구조물의 보수보강에 있어서의 FRP의 접착방법에 관한 것이다.The present invention repairs the concrete structure F in reinforcement R It relates to a bonding method of P.
[종래의 기술][Prior art]
콘크리트 구조물의 보수 ·보강방법에 있어서, 근래, 도로 교량의 상판, 빔,교각 등의 콘크리트 구조물을 섬유재를 이용하여 보수보강하는 방법이 주목되고 있다.In the repair and reinforcement method of concrete structures, in recent years, the repair of concrete structures, such as the top plate, beams, bridges, etc. of road bridges using fiber materials The method of reinforcement is attracting attention.
이 방법은 FRP 즉, 카본섬유, 아라미드섬유, 유리섬유 등을 시트 모양으로 한 섬유재에 에폭시 수지, 폴리에스테르 수지 등의 열경화형 접착제를 함침시켜, 이것을 콘크리트 구조물에 적층하여 접착일체화하여 콘크리트 구조물을 보수보강하려 하는 것이다.This way f R P, ie, impregnated with a thermosetting adhesive such as epoxy resin or polyester resin in a sheet material made of carbon fiber, aramid fiber, glass fiber, etc. It is trying to reinforce.
섬유재에 접착재를 함침시키는 방법은, 접착제를 구조물에 도포하고, 그위에 섬유재를 첩부한 후, 또는 미리 접착제를 부착한 섬유재를 구조물에 첨부한 후, 그위에서 롤러 , 고무주걱 등을 이용하여 가압하는 것이 보통이다.In the method of impregnating the adhesive material to the fiber material, the adhesive is applied to the structure, the fiber material is affixed thereon, or the fiber material to which the adhesive has been previously attached is attached to the structure, and then a roller or a rubber spatula is used thereon. Pressurization is common.
이같은 방법에 따르면, 콘크리트 구조물의 보수보강의 효과는 상당한 것이 있으나, 작업성에 몇가지 문제점이 있다.According to this method, the repair of concrete structures Although the effect of reinforcement is significant, there are some problems in workability.
우선, 접착제에 상당한 점도와 요변성이 없으면 접착제가 경화되기까지 사이에 구조물에 첨부한 섬유재가 구조물에서 벗겨지거나, 접착제가 처지거나 한다.First, if the adhesive does not have significant viscosity and thixotropy, the fibers attached to the structure may peel off from the structure or the adhesive sags until the adhesive cures.
그래서, 박리방지와 처짐방지를 위하여 접착제에 높은 점도와 요변성을 부여하면, 섬유재에의 접착제의 완전한 침투에는 장시간을 요하고, 대단한 곤란을 수반한다. 그 때문에 가압작업중에 섬유재 위치가 빗나가, 섬유의 사행, 부풀음 등이 생기기 쉬워진다. 이 같은 현상은 특히 동계 공사에 현저하다.Therefore, when high viscosity and thixotropy are given to the adhesive for preventing peeling and sagging, complete penetration of the adhesive into the fiber material takes a long time and entails great difficulty. Therefore, the position of the fiber material is missed during the pressurizing operation, and the meandering and swelling of the fiber tends to occur. This phenomenon is particularly noticeable in winter construction.
