[0002] The Yangshupu Industrial Zone, located on the Yangpu Riverside in Shanghai, is an important industrial base in modern China. 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 laying bricks, that is, removing the original deteriorated brick eaves and then re-laying them with mixed mortar for repair. If conventional bricks are used for this repair method, since only the new and old bricks are bonded with the new and old bricks, the horizontal tension is insufficient and easy to be damaged, resulting in the separation of the new and old bricks. In addition, since some brick surfaces, especially the upper surfaces of the topmost bricks, are easily eroded and damaged, the bonding surface of the mixed mortar is damaged, thereby causing the topmost bricks to fall off. Even if dovetail bricks with mortise and tenon structures are used for connection, it still cannot make up for the problem of insufficient bonding tension between the new and old brick surfaces using only mixed mortar.
