The present invention relates to a high-strength lattice girder. According to the present invention, a triangle connector of the present invention is a triangle connector placed in between a first steel rod (300) and a second steel rod (400), which are placed on the excavating surface of a tunnel to support the load, and comprises an angle (200) where the side ends of two square plates (210) come in contact to form a sharp edge unit (220). The sharp edge unit (220) is combined with the first steel rod (300), and the other side end of the square plate (210) is combined with the second steel rod (400). As well, the high-strength lattice girder comprising the triangle connector of the present invention additionally comprises a first steel rod (300) and a second steel rod (400) placed to be parallel to each other. Multiple supporting units (100) and angles (200) are formed on the first steel rod (300) and the second steel rod (400), which are formed to be extended, at a predetermined distance. |
