Counterweight type installation method of main beam
The invention relates to a counterweight type mounting method of a main beam. A mid-span side crane and a side-span side crane are respectively mounted on an assembled beam section at a cable bent tower; a movable counterweight module is arranged on the side span side according to the longitudinal gradient of the main beam; a side span beam section is hoisted to a beam moving trolley which is arranged on the middle span side in advance through the middle span side crane, and the side span beam section is transferred by the beam moving trolley to be hoisted by the side span side crane; the mid-span beam section is lifted by the mid-span side crane; the side span beam sections and the middle span beam sections are synchronously spliced with the spliced beam sections; and the position of the movable counterweight module is changed along with the change of the positions of the side span beam section and the middle span beam section on the main beam. When the two cantilevers are arranged on the two sides of the cable bent tower, and the load stress of the cantilever beam on one side of the cable bent tower is large, the movable balance weight module can actively move towards the cantilever beam on the other side of the cable bent tower, so that the load applied to the cantilever beam on the other side by the movable balance weight module can be balanced with the load borne by the cantilever beam on one side.
本发明涉及一种主梁的配重式安装方法，分别在索塔处已拼装梁段安装中跨侧吊机和边跨侧吊机；根据主梁的纵向坡度在边跨侧配置移动配重模块；边跨梁段通过所述中跨侧吊机吊装到预先配置在中跨侧的移梁小车上，由所述移梁小车中转至由所述边跨侧吊机提吊；中跨梁段通过所述中跨侧吊机提吊；所述边跨梁段和中跨梁段同步与所述已拼装梁段进行拼接；所述移动配重模块的位置随所述边跨梁段和中跨梁段在主梁上位置的变化而变化。在索塔两侧具有双悬臂时，在索塔一侧悬臂梁荷载受力较大时，移动配重模块能够主动向索塔另一侧的悬臂梁移动，使得移动配重模块施加给另一侧悬臂梁的荷载能够与一侧悬臂梁所受的荷载平衡。
