以一栋装配整体式剪力墙结构住宅为例,分析不同主体结构预制率对建筑整体装配率的影响,要达到装配率52%的要求,主体结构中除楼板、楼梯、阳台预制之外,梁也需要预制。若要评级,需要在竖向构件预制、干式工法楼面、集成厨房、集成卫生间方面突破。可为同类结构设计做参考。 相似文献

“装配式建筑”是指采用预制构件或部件,在施工现场装配而成的居住建筑和商业、办公等公共建筑。本市装配式住宅鼓励采用装配整体式混凝土结构体系,其建筑单体预制装配率应不低于装配式住宅预制装配率,建筑外墙、梁柱、楼板等混凝土主要构件宜采用预制方式。 相似文献

大力发展预制装配式混凝土结构,符合我国目前积极倡导的建筑工业化和住宅产业化的基本趋势,有利于实现低碳、绿色、环保、节能的建筑目标。在阐述了预制装配式剪力墙结构竖向连接的基本设计原则后,依据设计原则分析各个连接形式。系统归纳总结国内外正在发展的预制装配式剪力墙构件的七种竖向连接形式,并对各类连接形式的优势及尚存的问题进行评价和展望。结果显示,现有的预制装配式剪力墙结构竖向连接形式已经应用于实际工程,但是仍然存在不足之处,有待进一步研发更合理的连接形式。 相似文献

The paper describes a knowledge-based system for the detailed design of prefabricated building. The system employs a comprehensive approach which integrates different design aspects, architectural, structural and technological. The system receives, as an input, a preliminary architectural design of the building to be erected, adjusts it to a modular grid, indicates the location of structured supports, breaks down the floors and walls into elements to be prefabricated and finally produces detailed drawings of the elements and their cost estimate. The premise of the system, its operation and the structure of its knowledge are described. 相似文献

The aim of this study is to evaluate numerically the equivalent diameter of a prefabricated vertical drain (PVD) using an equal flow rate approach. This approach requires that the equivalent circular well to be able to yield similar discharge as a PVD well when subjected to similar pressure-controlled pumping condition. Simple equivalent diameter equation was obtained from the numerical study. The proposed equation is discussed in light of the equivalent diameter equations and experimental results currently available in the literature. The outcomes of this study give more insight in this subject and improve the method of calculating the equivalent diameter of a PVD well. 相似文献
