摘要
建筑逆作法施工中,钢格构柱的精确定位及垂直度控制是基础施工中的难点。武汉老浦片商业及住宅项目工程,设计制作出钢格构柱的导向架、定位架,方便快捷地完成钢格构柱的垂直度、定位调节。通过开挖后检测数据分析,采用本文所述方法施工,钢格构柱垂直度、定位均能满足设计要求,可有效降低施工成本。
For the construction with reverse construction method, the accurate positioning and verticality control of steel lat- tice column are difficult in the foundation construction. In Laopupian commercial and residential project of Wuhan, the guide frame and positioning frame of steel lattice column are designed and manufactured, the verticality and positioning ad- justment are smoothly completed. By the analysis on the detected data of the excavation with reverse construction method, it is proved that both the verticality and positioning can meet the design requirements with the newly designed guide frame and positioning frame, the construction cost is effectively reduced.
