Steel-concrete composite beam cable-stayed bridge construction system and steel-concrete composite beam construction method
The invention provides a steel-concrete superposed beam cable-stayed bridge construction system and a steel-concrete superposed beam construction method.The steel-concrete superposed beam cable-stayed bridge construction system comprises a beam bottom crane and a bridge deck crane, the beam bottom crane is arranged below a cantilever beam section and moves in the lengthwise direction of the cantilever beam section, and the bridge deck crane is arranged below the cantilever beam section and moves in the lengthwise direction of the cantilever beam section; the bridge floor crane is located above the front end of the cantilever beam section, the beam bottom crane is used for hoisting the assembled to-be-mounted steel beam section from the steel beam assembling support and transferring the assembled to-be-mounted steel beam section to the bridge floor crane, and the bridge floor crane is used for lifting the to-be-mounted steel beam section conveyed by the beam bottom crane to a specified height and splicing the to-be-mounted steel beam section with the mounted cantilever beam section. The whole steel beam sections are lifted to the to-be-constructed position to be assembled, the construction period of main beam installation does not need to be occupied, high-altitude operation is greatly reduced, the linearity of the main beam can be guaranteed, the construction speed is increased, and the safety risk is low.
本申请提供一种钢混叠合梁斜拉桥施工系统及钢混叠合梁的施工方法，其中，钢混叠合梁斜拉桥施工系统包括梁底吊机及桥面吊机，梁底吊机设于悬臂梁段的下方，且梁底吊机沿悬臂梁段的纵长方向移动，桥面吊机位于悬臂梁段前端的上方，梁底吊机用于从钢梁拼装支架处吊装拼装完成的待安装钢梁节段移送至桥面吊机处，桥面吊机用于将由梁底吊机输送的待安装钢梁节段提升至指定高度并与已安装的悬臂梁段拼接。本申请通过将整体钢梁节段进行提升至待施工位置进行拼装，无需占用主梁安装的施工工期，并且大幅减少了高空作业，并能保证主梁线性，加快了施工速度，安全风险低。
