Problems solved by technology
[0004] However, to test the structural glue joint in the hollow gap of the hollow glass panel, it is usually necessary to disassemble the hollow glass panel on site, and then perform various detection methods. The normal use of the substance has a great impact and the scope of use is limited

Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0029] figure 1 It is a schematic flowchart of a method for on-site detection of structural glue joints of insulating glass panels of existing hidden frame curtain walls in an embodiment of the present invention. Such as figure 1 As shown, the method for on-site detection of the structural glue joints of the hollow glass panels of the existing hidden frame curtain wall in the embodiment of the present invention includes:
[0030] Step 101, exposing the structural adhesive seam in the hollow interlayer of the hollow glass panel at a selected detection area. In practical applications, for the case where there is joint sealant between two adjacent insulating glass panels, this step can eliminate the joint sealant between two adjacent insulating glass pan...

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.
Description
technical field [0001] The invention relates to the safety detection technology of the existing hidden frame curtain wall, in particular to a method for on-site detection of the structural glue joint of the hollow glass panel of the existing hidden frame curtain wall, wherein the "existing" hidden frame curtain wall involved in the method It refers to the hidden frame curtain wall after the national standard acceptance, and this method is mainly aimed at testing the structural stress deformation performance (referred to as structural performance) of the structural glue joint. Background technique [0002] Insulating glass panels are usually made of two layers of glass with a gas (inert gas or air) interlayer in the middle, and the edges are usually sealed with sealant (including hygroscopic molecular sieves) to isolate the exchange of gas and atmosphere in the interlayer. For hollow glass panels used for hidden frame curtain walls, in addition to filling the above-mentioned ...
