AI Technical Summary
In the reinforcement project of increasing the cross section at the bottom of existing building beams, the traditional 135° hook is difficult to implement due to space constraints, resulting in insufficient anchorage force, a sharp drop in shear bearing capacity, weakening of the original main reinforcement and degradation of durability. Existing emergency treatment methods weaken the structural safety reserve.
The beam reinforcement stirrup anchorage pre-embedded parts are adopted, including a combination of longitudinal fixing parts, telescopic arms and sleeve fasteners. They are fixed to the beam body by anchoring adhesive to achieve secondary anchorage of U-shaped stirrups, ensure the tensile strength of stirrups and participate in subsequent stress, and enhance the integrity and load-bearing capacity of the interface between new and old concrete.
It significantly improves the integrity, stiffness, and load-bearing capacity of the composite section of new and old concrete, avoids the structural hazards caused by traditional methods, and meets the anchorage requirements of the specifications without increasing the thickness of the beam bottom.
