Bridge steel structure installation construction closure method
The invention provides a bridge steel structure installation construction closure method, and belongs to the field of steel structure installation construction closure, the method comprises the following steps: steel box girder installation construction, stay cable construction and closure section construction, the steel box girder installation construction comprises girder section hoisting, fine matching and temporary connection, the stay cable construction comprises the steps of construction site preparation work, stay cable on-bridge installation, stay cable tower end installation, stay cable unfolding, beam end installation, stay cable tensioning, cable adjusting and stay cable vibration reduction. The closure section construction comprises closure opening posture adjustment, closure opening monitoring, closure section matching and cutting, closure section hoisting, beam section precision matching, matching end setting, closure opening fixing at a matching and cutting end and system conversion. The temperature is detected in real time in the closure process, closure installation is conducted according to temperature data, the installation precision is higher, meanwhile, the stay cable is provided with two vibration dampers, a main beam vibrates along with the stay cable, and the situations that the root of the stay cable is subjected to fatigue damage, and measurement construction on the main beam is not accurate are caused.
本发明提供一种桥梁钢结构安装施工合拢方法，属于钢结构安装施工合拢领域，方法包括如下步骤：对钢箱梁安装施工、斜拉索施工和合龙段施工，钢箱梁安装施工包括梁段吊装、精匹配及临时连接，斜拉索施工包括施工现场准备工作、斜拉索上桥、斜拉索塔端安装、斜拉索展索、梁端安装、斜拉索张拉、调索和斜拉索减振；合龙段施工包括合龙口姿态调整、合龙口的监测、合龙段配切、合龙段吊装、梁段精度匹配、匹配端码定、配切端固定合龙口和体系转换。本发明在合拢过程实时对温度进行检测，然后根据温度的数据进行合拢安装，使得安装的精度更高，同时斜拉索设置两个减振，主梁跟随斜拉索振动，造成斜拉索根部疲劳破坏、主梁上测量施工不准等情况。
