Full precast frame steel support structure and construction method thereof

The invention relates to the technical field of construction engineering, in particular to a full precast frame steel support shear wall structure. The full precast frame steel support structure comprises a precast frame, a support and embedded parts, wherein the precast frame is arranged in the position where a cast-in-place shear wall is arranged and in a high-layer frame structure; the steel support is arranged in the precast frame and is connected with the precast frame through the embedded parts. The fully assembled frame-steel support structural system replaces the frame-shear wall system which needs cast-in-place for a part, so that full precast assembly of components of the high-layer frame structure is realized; precast assembly rate of the structure is improved; construction industrial technology of the high-layer frame structure is developed.
