The utility model discloses a triangular rigid frame and prefabricated assembled steel-concrete composite triangular rigid frame arch bridge. The triangular rigid frame consists of prefabricated front oblique column, rear oblique column, steel flat beam, front cross beam of the triangular rigid frame and rear cross beam of the triangular rigid frame, which are assembled into a triangular rigid frame entirety after prefabricated and divided into blocks; the front cross beam and rear cross beam of the triangular rigid frame adopt steel box structure, and the front oblique column and rear oblique The members are separated by steel lattices, and some of them are filled with concrete. Accordingly, the inventor applied it to prefabricated steel-concrete composite triangular rigid frame arch bridge, replacing the traditional triangular rigid frame structure with concrete filled in steel lattice box, in order to achieve the purpose of optimizing the structure form. The application of the utility model can achieve the effect of prefabrication and assembling of triangular rigid frame, reduce the weight of the structure and increase the construction convenience, thus greatly shortening the construction period, reducing the cost and reducing the construction risk, and achieving better construction quality. The utility model has extensive engineering application space and greater economic benefits.
