混凝土砌块建筑中裂缝的控制技术研究

Techniques for the Prevention of Crackingin Buildings of Concrete Blocks

对我国砌块建筑裂缝的防治方法进行了分析,特别是对“放”的概念作了重点阐述,在分析国内外对此概念理解的基础上,结合我国即将颁布的《砌块建筑技术规程》,提出了对于墙体开裂的具体设计理念和墙体水平配筋率和连接件的设计要求.

This paper discusses the techniques for the prevention of cracking in buildings of concrete blocks,with emphasis on the idea of “unrestrainedness”.On the basis of an analysis of the understanding of this idea both at home and abroad,and referring to the Technical Regulations for the Construction of Concrete Building Blocks(version for discussion),the author put foth his design notion to prevent cracking and the designing requirements in the horizontal ratio of reinforcement and in the connecting method.
