Erecting method of continuous steel truss girder bridge
The invention provides an erection method of a continuous steel truss girder bridge, and relates to the technical field of bridge erection, the erection method of the continuous steel truss girder bridge comprises the following steps: constructing a main body structure under a bridge and a swivel structure, and installing a pier top steel beam above a pier side bracket through a tower crane; symmetrically hoisting a preset number of steel beam sections along the two sides of the pier top steel beam through a tower crane, and hoisting a temporary buckling tower above the pier top steel beam; a buckling and locking tower frame is hoisted at the top of the temporary buckling tower through a tower crane, and two deck cranes are hoisted through the tower crane; symmetrically and synchronously hoisting the remaining steel beam sections through two deck cranes, and meanwhile, hanging temporary catches at corresponding positions and tensioning the temporary catches; and unnecessary construction loads on the bridge floor are removed, and swivel construction is conducted after the bridge body reaches a balanced state. Compared with the prior art, the mode that the steel beam sections are synchronously and symmetrically erected along the two sides of the middle pier is adopted, the requirement for construction errors is low, and the erecting efficiency of the continuous steel truss girder bridge is improved.
本发明提供了一种连续钢桁梁桥的架设方法，涉及桥梁架设技术领域，连续钢桁梁桥的架设方法包括施工桥下主体结构以及转体结构，通过塔吊在墩旁支架的上方安装墩顶钢梁；通过塔吊沿墩顶钢梁两侧对称吊装预设数量的钢梁节段，并且在墩顶钢梁上方吊装临时扣塔；通过塔吊在临时扣塔的顶部吊装扣锁塔架，并且通过塔吊吊装两台桥面吊机；通过两台桥面吊机对称同步吊装剩余钢梁节段，并且同时挂设相应位置的临时扣锁并进行张拉；清除桥面不必要的施工载荷，待桥体达到平衡状态后进行转体施工。本发明相比于现有技术，采用沿中墩两侧同步对称架设钢梁节段的方式，对施工误差的要求较低，提高了连续钢桁梁桥的架设效率。
