Self-anchoring structure and method for overall lifting of steel box girder
The self-anchoring structure comprises a bridge tower and a constructed steel box girder, the bridge tower is provided with an annular self-anchoring support body, the bottom of the bridge tower is provided with a support bottom embedded steel plate, the annular self-anchoring support body is connected with the support bottom embedded steel plate and the constructed steel box girder, the top of the constructed steel box girder is provided with a self-anchoring truss, and the self-anchoring truss is connected with the annular self-anchoring support body. And lifting equipment is arranged at one end, facing the mounting surface, of the self-anchoring truss. The invention further discloses a self-anchoring method for overall lifting of the steel box girder. The self-anchoring method comprises the following steps that firstly, the bottom pre-embedded steel plate of the support is fixed to the bottom of a bridge tower; 2, mounting an annular self-anchoring bracket body; thirdly, the prefabricated steel box girders are hoisted in situ, and the adjacent prefabricated steel box girders are welded to form constructed steel box girders; fourthly, steel box girder inner supporting circular pipes and self-anchoring trusses are installed on the constructed steel box girders; and fifthly, the to-be-hoisted steel box girder is installed. The steel box girder can be economically and reasonably lifted to the designated position, and the method can be widely applied to the field of building construction steel structure installation.
本发明公开了一种用于钢箱梁整体提升的自锚定结构，包括桥塔和已施工钢箱梁，桥塔设有环形自锚定支架体，桥塔底部设有支架底预埋钢板，环形自锚定支架体与支架底预埋钢板和已施工钢箱梁连接，已施工钢箱梁顶部设有自锚定桁架，自锚定桁架朝向安装面的一端设有提升设备。本发明还公开了一种用于钢箱梁整体提升的自锚定方法，步骤如下：一：桥塔底部固定支架底预埋钢板；二：安装环形自锚定支架体；三：原位吊装预制钢箱梁，焊接相邻的预制钢箱梁使其成为已施工钢箱梁；步骤四：已施工钢箱梁上安装钢箱梁内支撑圆管、自锚定桁架；步骤五：安装待吊装钢箱梁。本发明能经济合理地将钢箱梁提升至指定位置，可以广泛应用于建筑施工钢结构安装领域。
