备注

围绕国内外已开展的研究工作,介绍了我国最常用的两种预制装配式混凝土结构湿连接形式——套筒灌浆连接和浆锚搭接连接,分析了影响湿连接节点质量的各种因素,并评价了不同影响因素下湿连接节点质量缺陷的检测方法,以便实际工程中进行选用; 最后,总结与讨论了各国规范中装配式混凝土结构水平缝承载力的计算公式,为今后装配式混凝土结构湿连接的发展提供基础理论支持.
The most commonly used wet connection technology of precast concrete structure in China was introduced in this paper, included the sleeve grouting connection technology and the grout anchor lap connection technology. Various factors affecting the quality of wet connection were analyzed. The detection methods for the quality defects of wet-connected joints under different influence factors are evaluated for selection in practical engineering. Finally, the prediction formulas of horizontal joints bearing capacity of prefabricated concrete structures in various national codes were summarized and discussed. It provides basic theoretical support for the development of wet connection of prefabricated concrete structures in the future.
