Building curtain wall safety nondestructive testing imaging method based on microwave imaging

Abstract

The invention discloses a building curtain wall safety nondestructive testing imaging method based on microwave imaging, and the method comprises the following steps: respectively imaging defective curtain walls and newly built curtain walls under different working conditions, extracting imaging features of various defects, and taking the imaging features as identification elements of the defects to establish a feature library; setting detection equipment and carrying equipment, and confirming an initial acquisition position; carrying out comprehensive scanning detection on a to-be-detected curtain wall to realize microwave imaging; identifying a microwave imaging result, comparing the microwave imaging result with data in the feature library, marking working conditions with the same features, determining defect types, and reminding a person in charge to further observe and confirm; and determining a defect position and combining a defect type, and recording the defect position, the defect type and a non-conformance condition according to the conformance condition of the drawing, the standard and the feature library. According to the method, comprehensive scanning detection is completed on the premise that the original structure of the curtain wall is not damaged, accidental factors caused by sampling inspection are avoided, detection is more accurate, and the detection effect is good.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing of building curtain walls, in particular to an imaging method for safe and non-destructive testing of building curtain walls based on microwave imaging. Background technique [0002] Building curtain wall is the outer protective structure or decorative structure of the building. According to the panel material, it can be divided into glass curtain wall, aluminum curtain wall, stone curtain wall and wood-based panel curtain wall. Afterwards, it began to develop rapidly, and has exceeded 1.5 billion square meters so far, with a huge stock. At the same time, my country has gradually issued relevant standards for curtain walls since 1996. The curtain walls constructed before that lacked unified standard requirements. According to the "Unified Standard for Reliability of Building Structure Design" GB50068-2018, "Technical Specifications for Glass Curtain Wall Engineering" JG102-2003, etc...

AI Technical Summary

Problems solved by technology

With the gradual improvement of people's lives, the requirements for building curtain walls are getting higher and higher. However, due to reasons such as aging of structural adhesives, corrosion of metal parts, and shedding of panels, curtain wall safety accidents occur frequently, which poses serious threats to people's safe lives. threaten

[0003] At present, the mainstream detection methods for the safety inspection of existing curtain walls are mainly evaluated by experienced experts through visual inspection, hand testing and small tool detection, which are greatly affected by human factors; in addition, the bonding strength of structural adhesives, keel corrosion, The installation of pendants, the firmness of stone installation, etc. need to be dismantled for spot checks, which is accidental and likely to cause secondary damage or destroy the original structure; that is to say, there is no efficient and easy non-destructive testing method for curtain walls in the existing technology
