Description

Technical Field

[0001] The invention belongs to the technical field of glass processing damage detection, and in particular relates to a glass curtain wall processing damage detection method. Background Art

[0002] As a common decoration and enclosure structure for modern building facades, glass curtain walls integrate multiple functions such as aesthetics, lighting, and heat insulation, and are widely used in various commercial buildings, office buildings, and public facilities. With the rapid development of the construction industry, the scale of glass curtain walls has become larger and the structure has become more complex, which has put forward strict requirements on their processing quality and safety assurance.

[0003] In the processing flow of glass curtain walls, the glue injection and assembly process is extremely critical. The quality of glue injection is not only related to the stability of the connection between the glass plate and the frame, but also has a profound impact on the overall waterproof, airtight and seismic performance of the curtain wall. However, the current processing environment is full of many complex factors, such as differences in construction technology, fluctuations in raw material characteristics, human operating errors, etc., which may cause various types of damage to the glass curtain wall during the glue injection and assembly stage, such as uneven colloid filling, poor fit between glass and frame, and hidden tiny cracks. Traditional glass curtain wall damage detection methods have significant limitations. The visual inspection method relies too much on the experience and responsibility of the inspectors, and can only find more obvious appearance defects, but is powerless for damage hidden in the internal structure; although the knocking detection method can preliminarily judge the bonding condition, it is difficult to accurately locate the damage position, and the detection results are highly subjective; and conventional non-destructive testing technologies, such as ultrasonic testing and radiographic testing, are prone to misjudgment when facing complex multi-material composite structures such as glass curtain walls due to large differences in material acoustic properties and radiation absorption, and the detection accuracy cannot meet the needs of high-precision engineering.
