【摘要】：近年来,住宅工业化生产方式因其可实现工程建设的高效率、高品质、低资源消耗和低环境影响,具有显著的经济效益和社会效益,是当前住宅建设的发展趋势。因此国家高度重视住宅产业化的发展,其迅速发展进而带动整个国民经济结构调整升级并成为国民经济的一项重要支柱产业。目前国内装配式混凝土结构的现有技术仅限于纯框架结构和纯剪力墙结构,由预制柱、预制墙体、预制节点和预制梁构成的装配式混凝土框架剪力墙结构的相关研究和工程实践尚处于空白状态。装配式框架结构出于抗震考虑,其建筑高度受到限制,不符合现有市场对土地高利用率的要求。装配式剪力墙结构由于连接节点处工程量较大,连接工艺较复杂,且受使用空间及跨度的限制,目前仅限应用于部分商品楼、廉租房及经济适用房的建设中。而装配式框架剪力墙结构由于在框架结构中布置了部分剪力墙,有较大的抗侧刚度,建筑适用高度较高,同时又有灵活自由的使用空间,更能满足办公楼、商场、住宅等不同建筑功能的要求,具有广泛的发展空间,是未来装配式混凝土结构的发展方向。本文从装配式框架剪力墙结构拆分体系选型着手,提出几种拆分方案,进行经济技术指标对比分析,确定了本课题要研究的最优方案。并以沈阳建筑大学研究生公寓楼项目为试点工程,进行了从预制构件拆分设计、制作到现场拼装的一体化应用,其中：在设计阶段对预制构件拆分图进行了深化设计,探索并总结了拆分设计图的设计方法,使之适合预制厂工业化生产；在预制阶段解决了几项预制关键技术,摸索出各类预制构件的制作工艺,并对预制过程中的精度控制提出了几点建议；在现场拼装阶段进行了预制构件吊装就位及调整,总结出适用此种拆分体系的拼装顺序及方法。通过试点工程实际应用,并经过进一步的改进完善,最终得出一种较适合预制、拼装的装配式框架剪力墙结构拆分设计方法及其拼装技术。此种框架剪力墙结构拆分设计方法及其拼装技术具有结构合理,满足等同现浇原则,适合工业化生产及施工等优点,可为类似结构设计与施工提供参考。由于个人精力有限,本文尚未对预制构件拼装后整体抗震性能进行试验研究,在复合受力状态下以及动力性能需要进一步研究。
[Abstract]:In recent years, because of its high efficiency, high quality, low resource consumption and low environmental impact, the industrial production mode of housing has remarkable economic and social benefits. It is the development trend of housing construction at present. Therefore, the state attaches great importance to the development of housing industrialization, and its rapid development leads to the adjustment and upgrading of the national economic structure and becomes an important pillar industry of the national economy. At present, the existing technology of domestic assembled concrete structure is limited to pure frame structure and pure shear wall structure, which is composed of prefabricated columns and prefabricated walls. The research and engineering practice of prefabricated concrete frame shear wall structure composed of prefabricated joints and prefabricated beams are still in blank state. Due to earthquake resistance, the height of the assembled frame structure is limited, which does not meet the requirement of high utilization rate of land in the existing market. The assembled shear wall structure is limited to the construction of some commercial buildings, low-rent houses and comfortable housing because of the large number of projects at the joints, the complicated connection technology, and the limitation of the use space and span. But the assembled frame shear wall structure has some shear walls arranged in the frame structure, which has high lateral stiffness, high applicable height of the building, flexible and free use space at the same time, so it can meet the needs of office buildings and shopping malls. Different building functions, such as residential buildings, have a wide range of development space, and will be the future development direction of assembled concrete structures. This paper starts with the selection of split system of assembled frame shear wall structure, puts forward several split schemes, makes a comparative analysis of economic and technical indexes, and determines the optimal scheme to be studied in this paper. Taking the graduate apartment building project of Shenyang University of Architecture as a pilot project, an integrated application is carried out from split design of prefabricated components, production to field assembly, in which: in the design stage, the split drawing of prefabricated components is deeply designed. The design method of split design drawing is explored and summarized in order to make it suitable for industrial production of prefabrication plant. In the prefabrication stage, several key technologies are solved, and the fabrication process of all kinds of prefabricated components is explored, and some suggestions for precision control in the prefabrication process are put forward. In the stage of field assembly, the pre-fabricated components are placed in place and adjusted, and the assembly sequence and method suitable for the split system are summarized. Through the practical application of the pilot project and the further improvement and perfection, a kind of split design method and assembly technology of the assembled frame shear wall structure suitable for prefabrication and assembly is finally obtained. The split design method of frame shear wall structure and its assembling technology have the advantages of reasonable structure, equal cast-in-place principle, suitable for industrial production and construction, and can be used as reference for the design and construction of similar structures. Due to the limited personal energy, the overall seismic performance of prefabricated members has not been tested and studied in this paper. Under the condition of composite force and the dynamic performance, further research is needed.
