Installation method of landscape bridge of steel arch and steel frame space structure system
The invention discloses an installation method of a steel arch steel frame space structure system landscape bridge, and relates to the field of bridge construction. The installation method of the steel arch steel frame space structure system landscape bridge comprises the following steps: establishing a three-dimensional model by taking the steel main beam as a reference; based on the three-dimensional model, carrying out segment division, hoisting point setting and numbering processing on hoisting component segments of the landscape bridge of the steel arch and steel frame space structure system; an overall coordinate system is established on site according to the three-dimensional model, an inner suspender longitudinal base line, a steel frame longitudinal base line and an outer suspender longitudinal base line are drawn in the longitudinal bridge direction, a suspender node transverse base line is drawn in the transverse bridge direction, a support is erected, and the steel arch steel frame space structure system landscape bridge is installed; and after the inner suspender and the outer suspender are installed, tensioning and lifting are conducted at the same time till stress balance of the bridge is completed, and then the steel arch assembling support is disassembled. According to the installation method of the steel arch steel frame space structure system landscape bridge, the three-dimensional model is established so that theoretical data of control nodes of bridge construction can be conveniently extracted for measurement and positioning, the positioning accuracy of component segments can be improved, and the construction difficulty can be reduced.
一种钢拱钢架空间结构体系景观桥的安装方法，涉及桥梁施工领域。钢拱钢架空间结构体系景观桥的安装方法是以钢主梁为基准建立三维模型；基于三维模型对钢拱钢架空间结构体系景观桥的吊装构件节段进行节段划分、吊点设置和编号处理；在现场根据三维模型建立整体坐标系，沿纵桥方向绘制内吊杆纵基线、钢架纵基线、外吊杆纵基线，沿横桥方向绘制吊杆节点横基线，并搭设支架安装钢拱钢架空间结构体系景观桥，并在安装内吊杆和外吊杆后同时张拉提升直至桥梁完成受力平衡后拆卸钢拱拼装支架。钢拱钢架空间结构体系景观桥的安装方法通过建立三维模型以便于提取桥梁施工的控制节点理论数据进行测量定位，提高构件节段定位的精准性并降低施工难度。
