Description
Technical field
This utility model relates to material mechanical performance field tests, is particularly used for testing steel plate and glass adhesive strength
Pedestal.
Background technology
At present in the application process to glass, often refer to be bonded as one glass and steel plate, wherein, be used for gluing
The glass connect generally uses the one in common float glass, coated glass, laminated glass, double glazing, composite construction glass.
Because structure glue itself has preferable bearing capacity, also there is ageing-resistant, endurance, the performance such as corrosion-resistant, paste more convenient, its
Need not surface own to component during application weaken, good airproof performance, therefore, it is main that structure glue bonding becomes glass structure
Method of attachment.
Glass is bonding with steel plate typically require can permanently effective opposing wind load, gravity load, expand with heat and contract with cold, earthquake etc.
The combined influence of effect, requires high for the adhesive property between structure glue and steel plate.Glass and steel plate in some configurations
Between connection be glass end face and the contacting of steel plate major opposing side, interfacial structure glue is subjected to pressure, also can bear glass and steel
Plate shear action at bonding interface, therefore the bonding interface shear strength of accurate test and evaluation structure glue is for structure
Design and security reliability are evaluated most important.
Currently for the method for testing of bonding agent, structure glue bonding tensile shear fatigue behaviour mainly have ISO 9664,
The international standards such as ISO 4587, the plate sample of sample many employings folded type or lamination sample, typical bondline thickness is
0.2mm, there is following problem in this method when the interface shearing performance test of structure glue: (1) adhesive layer thickness is relatively
Thin, and the thickness of structure glue must suit the bondline thickness in engineering reality strength test when as far as possible；(2) between sample
The mode using overlapping is bonding, when the bonding way of glass and steel plate in practical structures be glass end face with steel plate major opposing side viscous
When connecing, it is impossible to simulate exactly；(3) glass is the fragile material that tensile strength is relatively low, it is difficult to bears bigger tensile load and makees
With；(4) only using specific one bonding length, assay device or process of the test do not test gluing under multiple bonding length
Connect intensity.Additionally, use conventional brace location glass during shearing test, rocking easily occurs in glass, and causes non-shear to break
Bad, this can affect test accuracy.
Utility model content
