Embodiment Construction

[0032] 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.

[0033] figure 1 It is a schematic flowchart of a method for on-site detection of structural glue joints of glass panel sub-frames of existing hidden frame curtain walls in an embodiment of the present invention. Such as figure 1 As shown, in the embodiment of the present invention, the method for on-site detection of the structural glue seam of the glass panel sub-frame of the existing hidden frame curtain wall includes:

[0034] Step 101, exposing the structural glue joint between the glass panel and the auxiliary frame at a selected detection area. In practical applications, for the case where the structural rubber joint is covered and protected by double-sided sealant, this step can expose the structural rubber joint in the detection area by removi...

Abstract

The invention discloses a method for field detection on a structural adhesive gap between a glass panel and a secondary frame of an existing hidden frame curtain wall. The method comprises steps that: step a, the structural adhesive gap between the glass panel and the secondary frame is exposed at a selected detection area; step b, segmental emptying on the exposed part of the structural adhesive gap is carried out to form discrete adhesive gap segments; step c, disassociated cutting on flanges of the secondary frame around the adhesive gap segments is carried out to acquire flange segments which are disassociated from a body of the secondary frame and are adhesive to the adhesive gap segments; and step d, field pulling force deformation tests on the adhesive gap segments are carried out through pulling the flange segments till the adhesive gap segments are pulled to break or a bonding interface is peeled or shed. According to the method, a structural performance check state of a structure adhesive is checked through a segmental emptying process, a measurement result of structural performance can be acquired through the pulling force deformation tests on the adhesive gap segments, moreover, operation of the method is simple, and influence on normal use of a building can be avoided.

Description

technical field [0001] The present 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 seam of the glass panel sub-frame of the existing hidden frame curtain wall, wherein the "existing" hidden frame involved in the method Curtain wall 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 of the structural glue joint (referred to as structural performance). Background technique [0002] In various hidden frame curtain walls, the glass panel is fixed to the main frame of the curtain wall through an auxiliary frame (which can be made of aluminum alloy material). Pay frame flange. However, if the bonding effect of the structural adhesive fails due to the aging of the adhesive, etc., the glass panel will fall off from the auxiliary frame, which will en...
