Abstract: In order to reduce the safety accidents in the construction stage of ROIB reconstruction and improve the safety of construction phase, the construction safety impact mechanism is studied according to the characteristics of old industrial buildings. According to the specific construction conditions of ROIB, the risk influencing factors are identified, and the influencing factors are analyzed by PCA and the index system is constructed,SEM is established based on the index system, and the influence mechanism is verified and analyzed, SEM analysis results are analyzed from the influence intensity and the influence path. The results show that the influence of external potential variables on construction safety performance is significant at 0.05 level, and the order of the importance of the factors is personnel factor, construction machinery and materials, construction environment and management and technical factors.

Key words: reconstruction of old industrial buildings(ROIB), construction safety, recycling, principal component analysis (PCA), structural equation modeling (SEM)
