This utility model belongs to the field of building structure reinforcement technology, specifically an ECC building structure reinforcement connector, including a first crossbeam; a second crossbeam overlaps the middle of the side wall of the first crossbeam; both the first and second crossbeams are provided with connecting components in the middle of their side walls, which can strengthen the connection between the first and second crossbeams; by setting a first
pipe clamp, a first short screw, a second
pipe clamp, a second short screw, a connecting plate, and a long screw, the two crossbeams can be firmly connected together to form a whole. This connection method can improve the connection strength between the crossbeams, enabling the structure to work better together when bearing loads, reducing the risk of damage caused by excessive local stress, and strengthening the overlap relationship of the crossbeams is equivalent to increasing the constraint conditions of the structure, making the structure more stable under stress, helping to reduce
structural deformation, improve the overall stiffness of the structure, and thus enhance the load-
bearing capacity of the structure.
