It is known as the "Corridor of Modern Chinese Industrial Civilization" and has been called "the world's only remaining industrial rust belt" by UNESCO. The industrial heritage historical buildings here play an important role in the history of modern industrial development in China. However, due to disrepair, weathering, rain erosion, etc., the exterior brick walls are damaged in many places, especially the cantilevered brick eaves structure of the brick walls is severely damaged, causing the original appearance of the historical buildings to be destroyed and urgently need to be repaired.
[0003] In the prior art, the repair method for the deteriorated brick eaves of the exterior walls of historical buildings often adopts the method of hollowing out and rebuilding, that is, removing the original deteriorated brick eaves and then rebuilding them with mixed mortar for repair. If conventional bricks are used for this repair method, the new and old bricks will only be bonded with the new and old brick surfaces, resulting in insufficient horizontal tension and easy damage, causing the new and old bricks to separate. Therefore, it is necessary to set tie bars inside the wall hole to avoid horizontal movement of the bricks. The original tie bar structure is prone to loosening between the tie bars and the bricks due to the large gap between the tie bar structure and the brick cavity and insufficient bonding force of the mixed mortar, thereby causing accidents.
