摘要
针对昆明新机场航站楼某超长、超高清水混凝土墙,解决了水平施工缝上部浇筑时的胀模、漏浆等问题,很好地控制了墙的垂直度、水平直线度和平整度。重点介绍了模板工程、钢筋工程以及混凝土工程的施工工艺,包括模板拼缝节点处理及安装、模板支撑体系、穿墙螺杆、施工缝处理等。并从加工、安装、拆除等方面说明模板拆除质量控制措施。既满足清水混凝土要求,又降低了成本。
Based on super-long and super-high fair-faced concrete wall in Kunming New Airport terminal,the problems of formwork expanding and mud leakage during concrete pouring upper horizontal construction joint are solved,and the verticality,horizontal straightness and smoothness are controlled excellently.The construction technologies of formwork engineering,reinforcement engineering and concrete engineering are introduced in detail,including treatment and installation of formwork edge joint,formwork support system,punching wall bolt and treatment of construction joint.Moreover,the quality control methods of formwork are indicated from aspects of processing,installation and demolition to meet fair-faced concrete requirement and save cost.
