Technical Field

[0001] The invention belongs to the technical field of construction engineering, and in particular relates to a repaired and reinforced brick factory building structure and a construction method thereof. Background Art

[0002] This project is a factory building for Chinese porcelain, which was built in the 1970s and 1980s.
