Analysis on Quality Control of External Wall Thermal Insulation Construction from the Perspective of Thermal Insulation Materials and Construction Technology

摘要: 外墙外保温是实现建筑节能降耗、改善室内热环境、延长围护结构使用寿命的关键构造做法，保温材料选型与现场施工工艺直接决定保温工程最终施工质量。本文从保温材料性能参数、进场验收管控、存储养护要点入手，梳理聚苯板、岩棉、挤塑板三类主流外墙保温材料理化特性与常见质量缺陷成因；围绕基层处理、粘结锚固、抹面抗裂、饰面层施工全工序工艺要点，剖析各环节违规施工引发的空鼓、开裂、脱落、渗水等工程通病。结合施工现场质量管理规范，从材料准入制度、工序精细化管控、现场质量验收、人员管理四个维度提出全过程质量管控措施，为建筑外墙保温工程质量通病预防与现场施工管理提供参考。

Abstract: External wall thermal insulation composite system serves as a critical structural measure to reduce building energy consumption, improve indoor thermal environment and extend the service life of building envelopes. The selection of thermal insulation materials and on-site construction techniques directly determine the overall construction quality of thermal insulation projects. Starting from the performance parameters, incoming inspection and storage management of thermal insulation materials, this paper analyzes the physical and chemical properties as well as common quality defects of three mainstream external wall thermal insulation materials, namely EPS board, rock wool board and XPS board. Following the full construction procedures, including base course treatment, bonding and anchoring, crack-resistant base coat construction and finish coating installation, it discusses common construction defects such as hollowing, cracking, peeling and water seepage caused by non-standard operation. In line with on-site construction quality specifications, whole-process quality control countermeasures are proposed from four perspectives: material access management, refined process control, field acceptance and personnel administration. The research can provide references for defect prevention and site management of external wall thermal insulation projects.
