Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering detection, and in particular to a system and method for detecting the quality of an exterior decoration layer of a high-rise building. Background Art

[0002] Due to construction quality, material quality, climatic conditions, biological erosion and other reasons, the exterior decorative layer of high-rise buildings may have quality problems such as hollowing, cracking, and hot and cold bridges during use. Such surface quality problems will reduce the overall energy-saving effect of the building.

[0003] The inspection and appraisal of the exterior decorative layers of existing high-rise buildings mainly rely on visual inspection and local damage detection by engineering and technical personnel. Not only is the workload large, but for buildings with an overall high height, it is impossible to accurately observe exterior wall defects with the naked eye. Exterior walls at higher locations are also difficult to detect for damage. At the same time, this method can only perform qualitative inspections on exterior wall quality issues, and cannot perform quantitative analysis on the hollow size of the surface layer, crack length, cold and hot bridge size, and detachment size.

[0004] Therefore, it is an urgent problem for those skilled in the art to propose a system and method for detecting the quality of the exterior decoration layer of a high-rise building to solve the difficulties existing in the prior art. Summary of the invention
