BIM-based shear wall construction joint formwork supporting and reinforcing device based on BIM

The invention discloses a BIM-based shear wall construction joint formwork supporting and reinforcing device. The supporting and reinforcing device comprises a rear wall body and four symmetrical bases, two connecting bosses are integrally formed on the upper surfaces of the bases, expansion bolts are in threaded connection with the inner side walls of the connecting bosses, and bosses are integrally formed on the upper surfaces of the connecting bosses. The four bases and fixing supports are matched with each other through connecting rods and connecting sleeves, so that the load resistance of a shear wall is improved, according to the bases and the connecting rods of the fixing supports, wherein an upper base and a lower base are arranged as a group, threads on the bases and the connecting rods of the fixing supports are matched with the connecting sleeves for mutual adjustment, and the functional requirement that due to the fact that the height sizes of shear walls of different buildings are different, heig
