Abstract

본 발명은 강성이 향상되고 격자지보와 숏크리트이 결합력을 향상시킨 보강된 격자지보를 개시한다. 본 발명은 터널을 따라 연장되는 상부 스틸바와 상기 상부 스틸바와 일정간격을 두고 상기 상부 스틸바를 따라 연장되는 하부 스틸바와 상기 상부 스틸바와 하부 스틸바를 연결하여 고정시키는 고정부재로 이루어진 보강된 격자지보에 있어서, 상기 상부 스틸바와 상기 하부 스틸바는 다각형 단면형상으로 이루어지고, 상기 고정부재는 다각형 단면을 이루는 상기 상부 스틸바의 일측면에 면접촉되는 상부접촉부와, 상기 상부접촉부의 양 끝단에서 각각 절곡된 상태로 상기 하부 스틸바를 향해 연장되는 연결부와, 각각의 상기 연결부의 끝단에서 절곡되어 다각형 단면을 이루는 상기 하부 스틸바의 일측면에 면접촉되는 하부접촉부로 구성됨으로써, 상수 스틸바 및 하부 스틸바와의 결합력과 강성이 향상될 수 있도록 한 것이다.
