装配式混凝土剪力墙结构竖向接缝干式连接技术研究进展

Research Progress on Vertical Joint Dry Connection Technology of Assembled Concrete Shear Wall Structure

干式连接是装配式混凝土剪力墙结构竖向接缝主要连接技术,具有工业化程度高、施工速度快等技术优势。在介绍干式连接技术的基础上,对比分析了焊接连接、预应力连接、螺栓连接的构造特征、受力性能及其技术优势与不足,指出螺栓连接可操性最好,面内螺栓连接技术是螺栓连接技术的重要发展方向。

Dry connection is the main connection technologies of vertical joints in assembled concrete shear wall structure,which has the advantages of high industrialization and fast construction speed.Based on the introduction of dry connection technology,the structural characteristics,mechanical properties,technical advantages and disadvantages of welded connection,prestressed connection and bolt connection are compared and analyzed.It is pointed out that bolt connection has the best maneuverability,and in-plane bolt connection technology is an important development direction of bolt connection technology.
