Steel box girder lateral sliding installation method
The invention relates to a steel box girder lateral sliding installation method, which comprises the following steps of arranging a counter-force seat at the end part of a bent cap on one side of a pier, erecting a bracket on the other side of the pier, and laying sliding rails on the bracket and the top surface of the bent cap in the transverse bridge direction, welding a sliding device to the bottom of the steel box girder in the transverse bridge direction, and welding an anchoring plate to one side of the steel box girder, hoisting the steel box girder onto the bracket, wherein a sliding device at the bottom of the steel box girder is supported on a sliding rail at the top of the bracket, and connecting a steel strand between the anchor pulling plate and the counter-force seat, arranging a center hole jack on one side of the counter-force seat, and enabling the center hole jack to drag the steel box girder to move to the position above the bent cap along the sliding rail through the steel strand. The problem that the lower-layer steel box girder cannot be directly hoisted when the steel box girders of the upper-layer bridge and the lower-layer bridge are simultaneously constructed is solved, installation of the lower-layer steel box girder is not affected by the upper layer, and the construction progress can be guaranteed.
本发明涉及一种钢箱梁侧向滑移安装方法，在桥墩一侧盖梁端部设置反力座，在桥墩另一侧搭设支架，在支架与盖梁顶面横桥向铺设滑轨；在钢箱梁底部横桥向焊接滑移装置，钢箱梁一侧焊接锚拉板；将钢箱梁吊放到的支架上，钢箱梁底部的滑移装置支撑在支架顶部的滑轨上；在锚拉板与反力座间连接钢绞线，反力座一侧设一穿心千斤顶，穿心千斤顶通过钢绞线牵引钢箱梁沿滑轨移动到盖梁上方。本发明解决了上下层桥梁的钢箱梁同时施工时，下层钢箱梁无法直接吊装的问题，下层钢箱梁安装不受上层影响，能保证施工进度。
