装配式混凝土梁柱节点连接形式研究进展

Research progress on connection forms of precast concrete beam column joints

装配式混凝土结构的发展是建筑行业转型升级路上的重要一环,而梁柱节点是装配式框架体系的关键部分。预制梁、柱的连接根据是否二次浇筑混凝土可分为湿式连接和干式连接。以连接形式为切入点,对国内外装配式混凝土梁柱节点的研究现状进行归纳,重点介绍节点连接形式研究的最新进展,提出未来研究方向以及可能存在的问题。

The development of precast concrete structures is an important part of the transformation and upgrading of the construction industry,and the beam column joints are the key parts of the prefabricated frame system.The connection of precast beams and columns can be divided into wet connection and dry connection according to whether the post pouring concrete is used.In this paper,taking the connection form of beam and column as the starting point,the research status of precast concrete beam column joints at home and abroad is summarized.The latest progress in the research of joint connection forms is highlighted,and the future research direction and possible problems are proposed.
