临沂文化广场整体建筑为门式造型,由于平台结构距地面近80m,结构跨度大,构件自重较重,结构总体采用吊装与提升结合的施工方案进行安装。结合现场实际施工条件,详细介绍了大面积裙房区地面拼装方案、高空大悬挑提升解决方案、提升工艺、同步控制策略及砂箱卸载方案等关键技术。结果表明该方案总体科学、经济、合理,确保了工程的顺利实施。
The overall building of Linyi Cultural Square is a portal-style. Since the platform structure is nearly 80m away from the ground, the structure span is large and the weight of components is heavy. The overall structure is installed by the construction scheme of lifting and lifting together. Combined with the actual construction conditions, the paper introduces in detail the key technologies such as the floor assembly plan of the large-area skirt house area, the solution of lifting at high altitude and large cantilever, the promotion of the process, the synchronization control strategy and the unloading plan of the sand box. The results show that the program overall scientific, economical and reasonable, to ensure the smooth implementation of the project.
