对《混凝土结构后锚固技术规程》中化学植筋部分内容的几点认识

Several Thinking on Chemical Anchorage Provisions in “Concrete Structure Post-anchoring Technology Specification”

《混凝土结构后锚固技术规程》JGJ145-2004/J407-2005发布实施以来,对我国混凝土结构后锚固技术的应用起到了重要的指导作用。在规范的实际应用中,由于工程技术人员对规范的理解不足,造成规范应用出现了较大的偏差,甚至是错误地应用了规范条文,本文结合实际工程案例,就规范中关于化学植筋锚固连接的设计和现场承载力检测进行了详细分析,并提出了相应的处理方法,对有关工程技术人员在应用规范时起到一定的参考意义。

Since the publication of ＂Concrete structure post-anchoring Technology specification＂ （ JGJ 145-2004/J407-2005 ）,it has provided important guidance for the application of post-anchoring technology in China. In its practical application, as a result of misunderstanding to standard by the engineers and technicians, a rather large deviation, even improper implementation of the application of specification occurred, This article connected with project cases to analyze the chemical anchorage design and in site bearing capacity testing, then proposed corresponding treatment, which could give some guidance for the related engineers and technicians.
