Construction method of arc-shaped steel box girder convenient to construct

CAO YANBING

The invention relates to the technical field of building construction, and discloses a construction method of an arc-shaped steel box girder convenient to construct. The method comprises the followingsteps of 1, prefabricating the arc-shaped steel box girder, and building a mold of the arc-shaped steel box girder on a building site by a worker; 2, installing a first arc-shaped steel box girder; 3, installing a second arc-shaped steel box girder; 4, connecting and fixing the first arc-shaped steel box girder and the second arc-shaped steel box girder; and 5, continuously completing subsequentinstallation between a third arc-shaped steel box girder and the second arc-shaped steel box girder and the subsequent installation between a fourth arc-shaped steel box girder and the third arc-shaped steel box girder till that the whole arc-shaped steel box girder is completed. According to the construction method of the arc-shaped steel box girder convenient to construct, installation stabilityof the arc-shaped steel box girder is guaranteed, a phenomenon of violent shaking is avoided, construction strength is small, and construction safety is guaranteed.

本发明涉及建筑施工技术领域，且公开了一种方便施工的弧形钢箱梁的施工方法，第一步骤：预制弧形钢箱梁，工作人员在建筑场地搭建弧形钢箱梁的模具；第二步骤：对第一弧形钢箱梁进行安装；第三步骤：对第二弧形钢箱梁进行安装；第四步骤：对第一弧形钢箱梁和第二弧形钢箱梁之间连接固定；第五步骤：持续完成将后续的第三弧形钢箱梁与第二弧形钢箱梁以及第四弧形钢箱梁与第三弧形钢箱梁之间的安装，直到完成整个弧形钢箱梁。该方便施工的弧形钢箱梁的施工方法，不仅保证了弧形钢箱梁的安装稳定性，而且不会剧烈晃动的现象，施工力度小，保证了施工安全性。
