【摘要】：中海鹿丹名苑8栋、9栋位于广东省深圳市罗湖区,抗震设防烈度为7度(0.1g),是首个政府要求满足建筑产业化指标的项目,均为高度超限工程,采用剪力墙结构体系。针对工程特点,所有外窗设计成内浇外挂型预制凸窗(共四种类型),且均在预制构件厂生产并运往工地装配成整体结构。根据预制构件在生产、脱模、起吊、运输、施工吊装、正常使用各阶段的受力特点对其进行受力分析和设计。考虑传力的可靠性、变形协调性、抗裂性、防水性等因素,合理设计凸窗与现浇部分的连接,并介绍了凸窗与铝模体系的连接。最后介绍了凸窗安装过程中的临时固定体系以及安装后的凸窗间缝隙的后期处理,并总结了此类预制凸窗在实践过程中的经验和教训。目前该项目仍在施工过程中,吸引了政府以及众多同行的参观,总体上是令人满意的。
[Abstract]:Located in Luhu District, Shenzhen City, Guangdong Province, 8 buildings and 9 buildings in Mingyuan District of Zhonghai Luodan, Guangdong Province, with a seismic fortification intensity of 7 degrees or 0.1 g, are the first projects required by the government to meet the requirements of building industrialization, all of which are highly exceeded projects. The shear wall structure system is adopted. According to the engineering characteristics, all the outer windows are designed as cast-in-place and externally mounted prefabricated convex windows (four types in all). All of them are manufactured in the prefabricated component factory and shipped to the site to assemble into an integral structure. According to the prefabricated components in production, demoulding, lifting, transportation, construction hoisting. The stress characteristics of each stage of normal use are analyzed and designed. Considering the reliability of force transmission, deformation coordination, crack resistance, waterproofing and other factors, the connection between the convex window and cast-in-place parts is reasonably designed. The connection between the convex window and the aluminum die system is introduced. Finally, the temporary fixing system during the installation of the convex window and the post-processing of the slot between the convex windows after installation are introduced. The experiences and lessons of this kind of prefabricated windows in practice are summarized. At present, the project is still under construction and has attracted visits from the government and many colleagues, which is generally satisfactory.
