Prestress reinforcing method for bridges
The invention discloses a prestress reinforcing method for bridges. The method comprises the following steps that S1, steel wires and a bridge are prepared; S2, a steel wire prestress tensioning and anchoring device is assembled; S3, steel wire installation and prestress tensioning are carried out; S4, the steel wires tensioned in the step S3 are installed on the bridge through bridge clamping parts in two anchorage devices; and S5, double-end connecting bolts are detached, then a fixed force transmission frame and a movable force transmission frame are detached for later use, and bridge reinforcing work is completed. According to the prestress reinforcing method for bridges, the steel wires are tensioned through jacks at first, and then the steel wires in the prestress state are installed on the bridge, so the problems that space for arranging jacks at the two ends of an existing beam in actual engineering is small, application is difficult and operation is inconvenient since columns or other bridges often exist at the two ends of the beam can be solved.
本发明公开了一种桥梁预应力加固方法，包括如下步骤：步骤S1：钢丝和桥梁准备；步骤S2：组装钢丝预应力张拉锚固装置；步骤S3：安装钢丝及预应力张拉；步骤S4：利用两个锚具中的桥梁夹持部将步骤S3中张拉后的钢丝安装到桥梁上；步骤S5：拆下双头连接螺栓，然后再拆下固定传力架和移动传力架，以备下次使用，至此桥梁加固工作完成。本发明的桥梁预应力加固方法，其先通过千斤顶对钢丝进行张拉，之后将呈预应力状态的钢丝安装到桥梁上，从而可避免现有梁的两端往往存在着柱子或其他桥梁，致使在实际工程中梁的两端布置千斤顶的空间较小，应用起来较困难，操作不便的问题。
