Example 2:

step S54: and determining a final result, analyzing the test result in the step S53, determining the effective tensile bonding strength value of the test, comparing the design value with the experimental value, and analyzing to determine the design value of the design section thickness and width of the structural adhesive.
The method for obtaining the design value of the ultra-wide and ultra-thick structural adhesive for the glass curtain wall is obtained through the embodiment 2, the obtained design value is used in actual use, namely, the embodiment 1, the ultra-wide and ultra-thick structural adhesive for the glass curtain wall is obtained through the embodiment 1, and the structural adhesive can be used for a curtain wall structure taking a glass wall of an ultra-large, ultra-thick and keel-free system as a self-bearing structural system.
The invention solves the defect that the strength is generated because the ultra-wide and ultra-thick structural adhesive is difficult to completely solidify. According to the specification of glass curtain wall engineering technical specification JGJ102-2003, the bonding width of the silicone structural sealant is not less than 7mm, and the bonding thickness is not less than 6mm and not more than 12 mm; the bonding width is preferably larger than the bonding thickness, but not larger than 2 times of the thickness, and the requirement is mainly to ensure that the structural adhesive can be completely coagulated and cured to generate the design strength.
Because the ultra-wide and ultra-thick structural adhesive exceeds the application range of the specification, if the existing one-step molding gluing scheme is adopted, the interior of the structural adhesive cannot be completely cured, so that the bonding strength of the structural adhesive is insufficient, and serious potential safety hazards are generated.
The invention discloses a design scheme of an ultra-wide and ultra-thick structural adhesive and a layered construction method thereof. The left glass panel and the right glass panel belong to overhanging components in terms of structural stress after being installed in place, and at the moment, the overhanging glass curtain wall structures at two sides are connected together through the tensile stress generated by the coagulation and solidification of the ultra-wide and ultra-thick structural adhesive in the middle, and are stressed together to achieve a stable state; however, the requirements of the condensation curing time and the strength of the structural adhesive on temperature and humidity are high, and particularly for ultra-wide and ultra-thick large-volume structural adhesives, the conventional one-time adhesive beating scheme is not suitable, and the scheme adopts a layered and staged adhesive beating scheme to achieve the stable strength state of the large-volume structural adhesive.
According to the invention, a layered glue injection method is adopted, so that structural glue is layered and fully cured, the strength of the structural glue is ensured, and meanwhile, after the glue injection in the first stage is completed, the dustproof maintenance is carried out on the glue injection interface, so that the two stages of glue injection interfaces are fully fused and the strength is jointly generated.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention are intended to be included in the scope of the present invention.
