Steel arch bridge hyperbolic arch space positioning, supporting and unloading integrated construction method
The invention discloses a steel arch bridge hyperbolic arch space positioning, supporting and unloading integrated construction method, and belongs to the technical field of steel structure bridge construction. The method comprises the following steps: 1) the plane positions of a supporting frame (1) and supporting plates (3) on a support platform (4) are accurately controlled through coordinates, the supporting plates (3) are located on the top of the supporting frame (1), and the two supporting plates (3) form an inwards-concave limiting groove which is gradually inclined outwards from bottom to top; and 2) the height of the supporting frame (1) can be increased and decreased by adjusting the length of a screw rod (8), so that the elevation of the hyperbolic arch of the steel arch bridge is accurately controlled, and unloading work after construction is completed is facilitated. Spatial positioning, supporting and unloading of the hyperbolic arch space of the steel arch bridge are integrated, and when a steel arched beam is a distorted variable-cross-section polygon, the mounting accuracy of the arched beam is guaranteed; and meanwhile, the height of a supporting base is adjustable, elevation positioning of the hyperbolic arch and unloading work after construction are convenient, and the overall construction quality and construction safety of the hyperbolic arch of the steel arch bridge are guaranteed.
一种钢拱桥双曲拱空间定位、支撑与卸荷一体化施工方法，属于钢结构桥梁施工技术领域。步骤1）在支撑平台（4）上通过坐标精确控制支撑架（1）和托板（3）的平面位置；托板（3）位于支撑架（1）的顶部，两片托板（3）组成由下至上逐渐向外的倾斜状的内凹型限位槽；步骤2）通过调节螺杆（8）长度，可升降支撑架（1）的高度，从而精确控制钢拱桥双曲拱的标高，并方便了施工完成后的卸荷工作。本发明将钢拱桥双曲拱空间定位、支撑与卸荷整合在一起，保证了钢拱梁为扭曲变截面多边形时，拱梁安装精确度；同时支撑支座高度可调，方便了双曲拱的标高定位与施工完成后的卸荷工作，确保了钢拱桥双曲拱的整体施工质量和施工安全。
