Bridge single-column pier reinforcing device with elastic self-resetting function
The invention discloses a bridge single-column pier reinforcing device with an elastic self-resetting function. The device comprises reinforcing and attaching components, a self-resetting platform, telescopic supporting rods, fixing pins and external prestressed tendons. The telescopic supporting rod is composed of two steel rods and two buckled steel sleeves, wherein external threads are prefabricated on the steel rods. The self-resetting platform is formed by assembling two steel plates through a rotating shaft and is fixed to the two sides of the single-column pier through fixing pins. The fixing pins are steel pins with strong restraining capability; the external prestressed tendons are rigging materials with high tensile bearing capacity and can be made of high-strength steel bars, high-strength steel strands or fiber reinforced composite material tendons (FRP). The device is integrally connected with the single-column pier, the connected reinforcing device can provide elastic self-resetting strong constraint for the beam body, and the effect of guaranteeing the safety of the beam body is achieved. The device is flexible, convenient, excellent in reinforcing effect and high in practicability, and the integrity and the self-bearing capacity of the single-column pier cannot be affected.
本发明公开了一种具有弹性自复位功能桥梁独柱墩加固装置。该装置包括加固贴合构件、自复位平台、可伸缩撑杆、固定销钉和体外预应力筋。可伸缩撑杆由两根预制有外置螺纹的钢杆和两个扣合的钢套筒组成；自复位平台由两个钢板经转轴组装、通过固定销钉固定于独柱墩两侧；固定销钉为具有强约束能力的钢制销钉；体外预应力筋为具有强抗拉承载能力的索具材料，可由高强钢筋、高强钢绞线或纤维增强复合材料筋(FRP)制成。本装置与独柱墩进行整体连接，连接后的加固装置可以对梁体提供弹性可自复位的强力约束，起到保障梁体安全的作用。本发明灵活便捷，加固效果优异，实用性强，并且不会影响独柱墩的完整性和自身承载能力。
