Description
Technical field
The utility model is related to the detections of structure glue, particularly for the detection device of the structure glue of glass curtain wall.
Background technology
Glass curtain wall is to assemble the structure outer of combination based on the glass curtain wall unit part that fluid sealant is bonded and sealed.
Glass unit is resiliently connected together with metal framework by structure sealant, and structure sealant plays construction bonds, is passed
Pass and undertake the stress of agent structure.
In the long-term use, the mechanical property of the structure sealant after aging, the adhesive property meeting kept with base material
Directly influence the safety and service life of glass curtain wall.Specifically, such as concealed frame glass curtain wall, once its structure sealant
Occur being hardened in use, become fragile, elasticity reduction, conjugate ability to bear deficiency and crack, bonding failure, may result in glass
Breathe freely leak, glass plate of glass curtain wall falls the generations of the accidents such as hurting people or smashing objects, seriously affects people's life and property safety.
Therefore, it is necessary to the performances to the structure glue used in existing curtain wall whether still effectively to make assessment.Existing silicone
Structure sealant check and evaluation method mainly uses destructive testing method, generally divides two methods：One is cut from curtain wall
Part-structure fluid sealant sample is removed, then carrying out sample preparation again in laboratory carries out Mechanics Performance Testing, and this method can not judge
The retainable quality of the caking property of structure sealant and base material.
Another method is to be detected at the scene, applies point loading or face to glass panel with puller system, jack etc.
Load, experiment needs large-scale plant to be difficult to operate, and the force value acted in four side structure glue of glass is inhomogenous, can not effective mould
The stressing conditions that wind load generates structure glue in quasi- practical application, while existing method is mostly to use " rubber tapping " form will be intrinsic
Structure glue cut certain length, later applied force make structure glue continue to destroy, according to structure glue continue destroy assessment of scenario knot
Whether the bonding of structure glue is effective, and this method can not judge that the elasticity of structure sealant conjugates whether ability to bear still has
Effect.
It can be seen that existing method can only be unilateral qualitative evaluation structure glue bonding effectiveness, have certain subjectivity
Judge, can not specify whether evaluation structure glue is effective, and destruction, operability are produced to the structure sealant of normal use
It is not strong.
