Angle-adjustable bridge single-column pier reinforcing device
The invention discloses an angle-adjustable bridge single-column pier reinforcing device, and belongs to the technical field of bridge engineering. The device comprises reinforcing components, telescopic supporting rods, fixing pins and external prestressed tendons. The telescopic supporting rod is composed of two steel rods with external threads and two steel sleeves with internal threads, the length of the telescopic supporting rod can be adjusted by rotating the sleeves, and attachment to bridge webs of different shapes and sizes is achieved. The external prestressing tendons are rigging materials with high tensile bearing capacity and are made of high-strength steel bars, steel strands and fiber reinforced composite material tendons, the external prestressing tendons and the steel fixing pins jointly restrain and reinforce the component, and the bearing capacity and stability of the top of the single-column pier are guaranteed. The device is integrally connected with the single-column pier, the connected integral structure enhances the anti-roll capacity of an original structure, deflection torsion of a beam body under the unbalance loading effect is relieved, and the effect of guaranteeing the safety of the beam body is achieved. The method is flexible and convenient, the reinforcing effect is excellent, and the integrity and the self-bearing capacity of the single-column pier cannot be affected.
本发明公开了一种角度可调式桥梁独柱墩加固装置，属于桥梁工程技术领域。该装置包括加固构件、可伸缩撑杆、固定销钉和体外预应力筋。可伸缩撑杆由两根外置螺纹的钢杆和两个内置螺纹的钢套筒组成，可通过旋转套筒来调节伸缩撑杆的长度，实现对不同形状尺寸桥梁腹板的贴合；体外预应力筋为具有强抗拉承载能力的索具材料，由高强钢筋、钢绞线以及纤维增强复合材料筋制成，其与钢制固定销钉共同约束加固构件，保证独柱墩顶部的承载力和稳定性。本装置与独柱墩整体连接，连接后的整体结构增强了原结构的抗侧倾能力，减缓偏载作用下梁体的偏向扭转，起到保障梁体安全的作用。本发明灵活便捷，加固效果优异，并且不会影响独柱墩的完整性和自身承载能力。
