Construction method of large-span steel structure corridor
The invention relates to the technical field of corridor construction, and discloses a construction method of a large-span steel structure corridor, in the corridor construction process, bottom main beams are firstly hoisted and installed in a segmented mode, then secondary beams and bottom steel bar truss floor support plates are laid, construction of the bottom of the corridor is completed, and then temporary supporting jig frames are hoisted and placed on the bottom steel bar truss floor support plates. And the top main beams and the top secondary beams are used for supporting the top of the corridor, finally, laying of the top steel bar truss floor bearing plates is completed, and overall construction of the corridor is completed. The steel beam is segmented through hoisting weight analysis, high-altitude in-situ hoisting is conducted on the weight of the steel beam within the hoisting weight range of the tower crane, the main beam needs to be installed firstly and then the secondary beam needs to be installed in construction, the diagonal draw bars are arranged on the two sides to reduce the overhanging length, the hoisting requirement of hoisting equipment is effectively lowered, the overall hoisting process is more flexible, and the hoisting efficiency is improved. Operation errors are reduced, time consumption is reduced, the site construction speed is higher, the power is higher, and it is guaranteed that a project is completed on schedule.
本发明涉及连廊施工技术领域，公开了一种大跨度钢结构连廊的施工方法，连廊施工过程中，先进行底部主梁的分段吊装安装，再铺设次梁和底部钢筋衍架楼承板，完成了连廊底部的施工，再在底部钢筋衍架楼承板上吊装放置临时支撑胎架，用以支撑连廊顶部的顶部主梁和顶部次梁，最后完成顶部钢筋衍架楼承板的铺设，完成连廊的整体施工。本申请通过吊重分析，将钢梁进行分段，使钢梁的重量在塔吊的吊重范围内进行高空原位吊装，施工上需先安装主梁后安装次梁，并在两侧设置斜拉杆以减少悬挑长度，有效降低了起重设备的起重需求，整体吊装过程中更为灵活，减少操作失误并降低时间上的消耗，使现场施工速度更快、功率更高，保证工程如期完成。
