装配式建筑灌浆套筒连接研究及发展现状

Research Progress on Grouted Splice Connector of Prefabricated Construction Building

装配式建筑是国内大力推广的结构体系之一,套筒灌浆连接作为预制构件间的主要连接方式对结构的整体性起着重要作用。本文从套筒的开发应用、灌浆料研究、套筒受拉性能研究及预制构件受力性能四个方面对钢筋套筒灌浆连接的发展、原理及现状进行梳理,为装配式建筑灌浆连接技术的发展和推广提供参考。

Prefabricated construction buildings was widely promoted in China as a main structural system.As the main connection technology for precast concrete components grouted splice connector is the key of structure integrity.This paper systematically summarizes the development,theory and current situation of grouted splice connector in four aspects:configuration of sleeve,grouting material,tensile performance and precast components performance,which has great significance to improve the connection technology and promote the application of grouted splice in China.
