Embodiment
For making object of the present invention, technical scheme and advantage clearly understand, to develop simultaneously embodiment referring to accompanying drawing, the present invention is described in more detail.
Fig. 1 is the schematic flow sheet of the method for the structure glue-line of the double glazing panel of the existing frame concealed curtain wall of Site Detection in the embodiment of the present invention.As shown in Figure 1, in the embodiment of the present invention, the method for the structure glue-line of the double glazing panel of the existing frame concealed curtain wall of Site Detection comprises:
Step 101, is sewn on selected surveyed area place and exposes by the structure glue in the hollow sandwich of double glazing panel.In practical application, for the situation that there is joint seal glue between adjacent two pieces of double glazing panels, this step can make structure glue be sewn on the exposure of surveyed area place by the joint seal glue removed at surveyed area between two pieces of adjacent double glazing panels.
Step 102, carries out segmentation to the part of the exposure of structure glue-line and empties, adjoins to form two ends the discrete glue section emptying gap.In practical application, this step can utilize the instrument such as graver and tweezers to realize segmentation and empty, and such as, first utilizes graver the part of the exposure of structure glue-line be cut into strip or bulk broken section and then draw out each broken section one by one with tweezers.
Wherein, process is emptied by the segmentation in this step, the bonding situation of structure glue-line and glass plate can be checked, bonding situation described herein can comprise adhesive surface and destroy situation and/or glue Cohesive failure situation, the degree that adhesive surface destroys is lower, or glue Cohesive failure degree is higher, can think that the inspection situation of structural behaviour is better.
Step 103, that empties formation in segmentation empties gap location, and the discrete glue section emptying formation to segmentation is carried out on-the-spot extruding force and loaded test, discrete glue section is deformed in hollow sandwich until rupture or bonding interface stripping damage occurs.In practical application, this step can utilize be embedded in the loading blocks emptied in gap realize on-the-spot extruding force load test.
Wherein, load test by extruding force in this step, such as extruding force loaded value can be obtained, and the distortion of discrete glue section and damage-form isostructuralism energy measurement result, and structural behaviour measurement result is given record, for load-bearing capacity and the deformation performance of analytical structure glue-line.
So far, one-time detection flow process terminates.Wherein, " inspection " in one-time detection flow process can be realized by step 102, " survey " then can be realized by step 103.
