The waterproof failure and construction quality fluctuation of joints in prefabricated concrete components of prefabricated buildings are key issues that restrict their durability and safety. This article focuses on the two core objectives of improving the waterproof performance of joints and controlling construction quality. It systematically analyzes the influencing factors of joint waterproofing, proposes optimization paths from the aspects of materials, construction, and technology, and based on this, constructs a four-dimensional construction quality control system of "quality planning quality control quality assurance quality improvement", clarifying the control measures for the three key links of personnel, materials, and processes. Research has shown that this system can significantly improve the reliability of joint waterproofing and the stability of construction quality, providing theoretical support and practical reference for the quality assurance of prefabricated building projects.
