Abstract
The invention discloses a method for detecting a structural glue line of a hollow glass panel of an existing hidden framing curtain wall in field. The method comprises the following steps: step a, exposing the structural glue line in a hollow interlayer of the hollow glass panel in a selected detection region; step b, hollowing out the exposed part of the structural glue line by sections to form a dispersed glue section with the two ends which are adjacently connected with a hollowed-out gap; and step c, carrying out a field extrusion force loading test on the dispersed glue section in the hollowed-out gap to deform the dispersed glue section in the hollow interlayer until the dispersed glue section is cracked or is stripped and damaged on a bonding interface. According to the method, a bonding condition of structural glue is detected in a sectioned hollowing-out process and a measurement result of the structural glue line can be obtained by the extrusion force loading test. Furthermore, a space limit caused by a hollow crack can also be overcome without detaching the hollow glass panel, so that the normal utilization of buildings is prevented from being influenced by detection and the detection is easy to operate.
