摘　　要：钢筋灌浆套筒连接是当今大多数混凝土装配式剪力墙结构设计选用的一种连接方式。此类装配式结构质量控制重点在于套筒连接的可靠性,也就是灌浆质量的关键影响。套筒灌浆质量控制对于冬期施工项目的流水施工具有关键的影响。为了保证冬期低温环境下,在满足灌浆质量、结构安全基础上,按正常施工节奏组织施工,通过研究低温环境采取有针对性的施工保温及升温措施进行灌浆施工的活动,探讨冬期预制混凝土结构节点连接的质量要求。The steel grouting sleeve connection is a commonly selected method in most of prefabricated shear-wall concrete structure designs today. The key quality control point of such prefabricated structure is the reliability of the sleeve connection, that is, the critical influence of the grouting quality. The quality control for sleeve grouting has a critical influence on the flow construction of winter construction projects. In order to ensure the construction can be carried out at the normal construction pace under the low temperature environment in winter and the case of satisfying the grouting quality and structural safety, niche-targeting construction insulation and warming measures are adopted to conduct grouting construction by studying the low temperature environment, and quality requirements for joint connections of prefabricated concrete structures in winter are discussed.
