SI体系保障性住房的产业化机理与实现路径研究

SI housing is kinds of combined housing which can be separated into the skeleton and the infill. It could give full play to the respective advantages of both the skeleton (steels, concrete, etc.) and the infill (partition walls, kitchen and toilet facilities, etc.). It could provide housings with variable space, long life, energy saving and easy to construct. What's more, it offers an important platform for the large-scale and industrial housing construction. However, the SI system isn't equal to the industrialization. It needs to solve lots of technical and management problems and develops along with the scientific and reasonable path to achieve the industrialization. This project takes the indemnificatory housing construction as the carrier, studies the application of SI system on indemnificatory housing construction, and also studies the mechanism how the construction of industrialization could improve the residential product quality, save the construction period and increase the construction level. First, the project carries on the research on the relationship analysis of SI system, indemnificatory housing, and housing industrialization to find a breakthrough of applying industrialization to SI system. Second, the structure and classification of SI system is analyzed, and the applicability research of modulization and building components constructed in the form of parts is conducted to create the conditions for the standardization and large-scale production of parts. Third, the new management techniques of the modern industrial production are introduced to study the forms of enterprise organizations and industrial organizations appropriate for the industrialization development of indemnificatory housing with SI system. The operation and management of such enterprises are also studied. Finally, this project carries on the researches on the process, steps and path of realizing industrialization promoted by SI system, providing a theoretical basis for realizing industrialization of SI system.

SI体系住宅是支撑体Skeleton与填充体Infill分离的住宅，它可以充分发挥钢材、混凝土等结构体与填充体如内隔墙、厨卫设施等各自的优势，实现住宅的空间可变、长寿命、节能和易于施工，并为住宅建设产业化提供重要的平台。但SI体系并不等于产业化，它还需要解决很多技术与管理问题才能实现。本课题以保障性住房为载体，将SI体系应用于保障性住房建设，研究通过产业化的建造方式来提高住宅产品质量、缩短工期。课题首先分析论述SI体系、保障性住房和住宅产业化三者的关系，为产业化方式应用于SI体系寻求突破口；然后分析SI体系的构成和划分，并进行部品化和模数化的适用性研究；其次引入现代工业化生产的新型管理技术，研究适合SI体系保障性住房产业化发展的企业组织形式和产业组织形式，研究此类企业的运作与管理；最后研究SI体系推进产业化的过程、步骤与实现的路径，为顺利实现SI体系的产业化提供依据。
