Fabricated anchor cable steel frame structure for existing line slope reinforcement and construction method

An assembly type anchor cable steel frame structure comprises an anchoring node component, two steel cross beam components and two steel longitudinal beam components. The structural sizes of the steel longitudinal beam components and the steel transverse beam components are consistent; bolt holes are reserved in the ends of the steel cross beams, the steel longitudinal beams and the anchoring joint components, and all the components and the adjacent steel frame beams are connected through the steel base plates and the reserved bolt holes through bolts to form the complete cross-shaped assembly type anchor cable steel frame beam. A traditional cast-in-place reinforced concrete frame beam is replaced by the asymmetrical I-shaped steel frame capable of being assembled, the assembly process is simple and convenient, and the situation that the construction period is limited due to concrete curing is avoided; the asymmetric I-shaped steel frame produced in a factory standardization mode is high in forming quality,
