Pier column slimmed steel truss landscape bridge and construction method thereof
The invention provides a pier stud slim steel truss landscape bridge and a construction method thereof.The pier stud slim steel truss landscape bridge comprises a steel truss, slim pier studs, pier stud foundations, bridge abutments and end supports, the steel truss is an upper structure of the bridge, the slim pier studs are steel structural members and bear tension, the upper ends of the pier stud foundations are connected with the slim pier studs, and the lower ends of the pier stud foundations are connected with the bridge abutments. The bridge abutment comprises an abutment body and a foundation of the abutment body, and the end supports are connecting supports between the two ends of the steel truss and the bridge abutment body. Before the slim pier column is installed, a temporary ballasting load larger than the second-stage dead load and the use live load of the bridge is applied to the steel truss behind the falling frame, and after the slim pier column is installed, the temporary ballasting load is removed. The pier column bears tension all the time in the using process of the bridge, the problem that the pier column is pressed to be unstable is solved, a high-strength steel structure component can be adopted, the pier column is thinned, the bridge landscape effect is improved, the utilization rate of the steel truss steel strength can be remarkably increased, and material waste is reduced.
本发明提出了一种墩柱纤细化的钢桁架景观桥及其建造方法，包括钢桁架、纤细化墩柱、墩柱基础、桥台和端支座，所述钢桁架为桥梁的上部结构，所述纤细化墩柱为钢结构构件且承受拉力，所述墩柱基础上端与纤细化墩柱相连，所述桥台包括台身及其基础，所述端支座为钢桁架两端与桥台台身之间的连接支座。所述纤细化墩柱安装前，在落架后的钢桁架上施加大于桥梁二期恒载和使用活载的临时压重荷载，完成纤细化墩柱的安装后，卸除该临时压重荷载。墩柱在桥梁使用过程中一直承受拉力，不存在受压失稳问题，可以采用高强度的钢结构构件，实现了墩柱的纤细化，提升了桥梁景观效果，本发明还可以显著提高钢桁架钢材强度的利用率，减少了材料的浪费。
