Reinforced concrete through arch bridge suspender direct replacement structure and replacement method thereof
The invention discloses a reinforced concrete through arch bridge suspender direct replacement structure and a replacement method thereof, belongs to the technical field of bridge engineering, and aims to solve the problems that a single suspender of a reinforced concrete through arch bridge needs to be replaced by means of a temporary tensioning and dragging device, bridge traffic needs to be interrupted, and time and labor are wasted. The structure comprises a suspender, an arch rib and a cross beam, wherein the suspender is arranged between the arch rib and the cross beam, the suspender isa double-suspender component, the double-suspender component comprises a first anchor rod, a first cable distributing plate, a suspender unit, a second cable distributing plate and a second anchor rodwhich are sequentially arranged from top to bottom, a first screw sleeve is arranged between the suspender unit and the first cable distributing plate, and a second screw sleeve is arranged between the suspender unit and the second cable distributing plate. The method comprises primary replacement and secondary replacement. The suspenders can be replaced one by one through portable equipment, thestress reasonability of a bridge structure can be guaranteed, and great convenience is brought to cable replacement construction.
本发明公开了一种钢筋混凝土下承式拱桥吊杆直接更换构造及其更换方法，属于桥梁工程技术领域，以解决钢筋混凝土下承式拱桥的单吊杆在更换中需要借助临时张拉拖换装置、桥梁交通需中断、费时费力的问题。装置包括吊杆、拱肋、横梁，吊杆设在拱肋与横梁之间，吊杆为双吊杆构件，双吊杆构件包括自上而下依次设置的第一锚杆、第一分索板件、吊杆、第二分索板件、第二锚杆，吊杆与第一分索板件之间设有第一螺杆套件，吊杆与第二分索板件之间设有第二螺杆套件。方法包括初次更换和二次更换。本发明使用便携式设备就能实现逐个吊杆的更换，不仅可以保证桥梁结构受力的合理性，也为换索施工带来极大的便利。
