Construction structure and method for jacking steel box girder in active service
The construction structure comprises a fixed base, a first sliding arm and a second sliding arm, the first sliding arm and the second sliding arm are used for adjusting the jacking width of a box girder body, the first sliding arm is movably installed on one side of the second sliding arm, and the first sliding arm and the second sliding arm are arranged side by side; one end of the first sliding arm and one end of the second sliding arm are both movably mounted in the fixed base and are driven by a two-way screw rod; a plurality of sets of lifting columns used for jacking a box girder body are fixedly installed at the upper end of the first sliding arm and the upper end of the second sliding arm, a first jacking base and a second jacking base are movably installed on one side of each lifting column, and the first jacking bases and the second jacking bases are vertically arranged side by side. The device has an alternate steel box girder jacking function, a traditional hoisting type steel box girder installation mode is replaced, the stability and safety of the steel box girder during installation are improved, the steel box girder is prevented from inclining and shaking, meanwhile, the device can be freely adjusted according to the width of a box girder body, and the application range of the device is widened.
本发明公开一种现役钢箱梁顶升的施工结构及方法，包括固定基座、用来调节箱梁体顶升宽度的第一滑臂和第二滑臂，第一滑臂活动安装在第二滑臂的一侧，第一滑臂和第二滑臂并排设置，第一滑臂和第二滑臂的一端均活动安装在固定基座的内部，第一滑臂和第二滑臂的一端通过双向丝杆驱动；第一滑臂和第二滑臂的上端均固定安装有若干组用来顶升箱梁体的升降柱，升降柱的一侧活动安装有第一顶升座和第二顶升座，第一顶升座和第二顶升座之间呈竖向并排设置；令其具有交替式钢箱梁顶升功能，代替传统的吊装式钢箱梁安装方式，提升钢箱梁安装时的稳定性和安全性，避免钢箱梁出现倾斜晃动现象，同时可以根据箱梁体宽度进行任意调节，提升其适用范围。
