【摘要】:随着新型建筑材料的应用、建筑技术的发展、人工成本的增长以及人们对于住宅节能要求的提高,住宅工业化设计建造成为建筑业新的发展趋势。住宅工业化设计建造可以提高生产效率和整体质量,并有效降低建筑能耗,这与保障性住房建设的要求非常吻合。对于保障房建设的推动与发展有重要的现实意义。 本论文为“十二五”国家科技支撑计划项目“保障性住房工业化设计建造关键技术研究与示范”的子课题。分别对建华(轻质陶粒混凝土材料)墙板、华丽(复合材料)墙板两种墙板组成的装配式围护结构的抗风性能进行试验研究,并通过数值模拟对试验结果进行验证,为保障房工业化设计建造提供依据和参考。 本论文试验为装配式围护结构均布荷载加载试验,试验设计主要参考了《装配式混凝土结构技术规程》等建筑规范、保障房围护结构抗风性能要求及试件承载力简化理论分析。本试验根据是否填充砂浆、墙板厚度、连接件厚度、连接方式等材料参数共制作了17个围护结构试件。 本次试验研究取得了阶段性成果,得到如下结论:建华墙板组成的装配式围护结构抗风性能主要取决于墙板厚度、连接方式、连接件厚度,是否填充砂浆对于此种装配式围护结构抗风性能提升没有作用;根据规范要求,对于满足保障房使用的装配式围护结构抗风性能,推荐采用150mm厚度建华墙板,3mm厚度Q235钢连接件,上下连接的连接方式,无填充砂浆。华丽墙板组成的装配式围护结构抗风性能主要取决于华丽墙板自身的强度。使用厚度更高的华丽墙板能够提升此种装配式围护结构的抗风性能,但是由于华丽墙板自身强度较差,华丽墙板不能满足装配式外围护结构抗风性能的要求,只能应用于建筑内部围护结构中。
[Abstract]:With the application of new building materials, the development of building technology, the increase of labor cost and the improvement of energy saving requirements for residential buildings, the industrial design and construction of housing has become a new trend of development in the construction industry. The industrial design and construction of residential buildings can improve the production efficiency and overall quality, and effectively reduce the building energy consumption, which is very consistent with the requirements of the construction of affordable housing. The promotion and development of indemnificatory apartment's construction has important practical significance. This paper is a subproject of the National Science and Technology support Program of the Twelfth Five-Year Plan, "the Research and demonstration of key Technologies in the Industrial Design and Construction of affordable Housing". The wind resistance of two kinds of wall panels composed of Jianhua (lightweight ceramsite concrete) and ornate (composite) wallboards are studied, and the experimental results are verified by numerical simulation. For indemnificatory apartment industrialization design and construction to provide the basis and reference. In this paper, the test is made for the uniform load loading test of assembled enclosure structure. The design of the test mainly refers to the building code such as Technical Specification for Assembly concrete structure, the requirements for wind resistance of indemnificatory apartment enclosure structure and the simplified theoretical analysis of the bearing capacity of the test piece. According to whether the mortar is filled, the thickness of wall board, the thickness of connectors, the connection mode and other material parameters, a total of 17 enclosing structural specimens have been made. The experimental results are as follows: the wind-resistant performance of Jianhua wall panel is mainly determined by the thickness of wall panel, connection mode, connecting part thickness, and so on. Whether the mortar is filled has no effect on improving the wind resistance of the assembled enclosure structure; According to the specification, it is recommended that 150mm thickness Jianhua wall board, 3mm thickness Q235 steel connection, upper and lower connection mode, and no filled mortar should be used to meet the wind resistance performance of the assembled enclosure structure used by indemnificatory apartment. The wind-resistant performance of the prefabricated retaining structure mainly depends on the strength of the splendor wallboard itself. The use of the thicker ornate wallboards can improve the wind resistance of the fabricated envelope structures, but because of the poor strength of the decorative wallboards themselves, the gorgeous wallboards cannot meet the requirements of the wind resistance of the fabricated exterior enclosures. Can only be used in the building interior enclosure structure.
