Analysis of Quality Control Technology for Grouting Construction of Assembled Shear Wall Structure Nodes

摘要:

装配式剪力墙套筒灌浆施工普遍存在空洞、漏浆、钢筋锚固不足等问题,严重影响装配式剪力墙结构施工质量。文章以某装配式住宅项目为研究对象,系统性分析装配式剪力墙结构节点灌浆施工常见的质量缺陷问题及形成因素,并提出灌浆施工全流程标准化质量控制技术。工程实践表明,采用该质量控制技术可以将装配式剪力墙结构节点灌浆饱满度提升到96.1%,一次施工合格率提升到95.0%,并将套筒空洞缺陷降低为4.1%,仓缝漏浆缺陷降低为2.5%,钢筋插入不足缺陷降低为1.7%,有效提升装配式剪力墙结构节点灌浆施工质量。

Abstract:

The grouting construction of prefabricated shear wall sleeves commonly suffers from problems such as voids, leakage of grout, and insufficient anchoring of steel bars, which seriously affect the construction quality of prefabricated shear wall structures. The article takes a prefabricated residential project as the research object, systematically analyzes the common quality defects and formation factors in the grouting construction of prefabricated shear wall structure nodes, and proposes standardized quality control technology for the entire grouting construction process. Engineering practice has shown that the use of this quality control technology can increase the grouting fullness of prefabricated shear wall structure nodes to 96.1%, improve the one-time construction qualification rate to 95.0%, reduce sleeve cavity defects to 4.1%, warehouse joint leakage defects to 2.5%, and insufficient steel bar insertion defects to 1.7%, effectively improving the grouting construction quality of prefabricated shear wall structure nodes.
