超高层建筑屋顶超限花架悬挑钢筋混凝土梁的施工组织与质量管控

Construction Organization and Quality Control of Ultra-limit Pergola Type Cantilever RC Beam in Super High-Rise Building Roof

针对成都启阳恒隆广场项目1#楼屋顶超限花架悬挑钢筋混凝土梁的施工难点,提出了多个施工对策,并通过对各方案进行成本、质量、安全的对比分析,结合项目实际情况,对屋顶超限花架悬挑钢筋混凝土梁施工过程中的方案选择以及质量控制进行了介绍,以期为类似工程提供借鉴。

Taking Hang Lung Plaza in Qiyang, Chengdu, as an example, specific to construction difficulties of ultralimit pergola type cantilever beam of 1^# building roof with ultra-high, super-long, and extra heavy structure, this paper puts forward several countermeasures, while at the same time, it also compares and analyzes the cost, quality and safety of each construction schemes. Based on actual project situation, one scheme selected for the construction of ultra-limit pergola type cantilever beam has been introduced from the perspective of quality control, which can provide references for similar projects.
