Glass curtain wall material testing

Glass curtain wall material testing
: Architectural glass curtain wall testing is divided into: laboratory testing and on-site curtain wall structural reliability testing
On-site reliability testing of curtain walls
) Under what circumstances is it necessary to conduct glass curtain wall testing? On-site security testing?
Failure to design, construct and accept in accordance with glass curtain wall specifications
Insufficient quality assurance of engineering and technical data
Before resuming construction of glass curtain wall project
Appears after an earthquake, fire, or strong wind attack Curtain wall damage
The curtain wall glass is broken and the opened part falls or the components are damaged
Quality problems are found during the use of the glass curtain wall, and the owner requires an evaluation
:) Specializing in the safety and reliability of building curtain walls Various performance tests and glass curtain wall safety performance testing and evaluation include the following contents:
Testing of glass curtain wall materials
Calculation of structural bearing capacity of glass curtain walls
Testing of glass curtain wall structures and structures
/> : According to the relevant content of the "Construction Quality Acceptance Code for Building Energy-saving Projects" B, when the materials and components used in curtain wall energy-saving projects enter the site, their following properties should be re-inspected. The re-inspection should be witnessed and sampled for inspection:
Insulation material: thermal conductivity density.
Curtain wall glass: visible light transmittance, heat transfer coefficient, shading coefficient, insulating glass dew point.
Insulating profiles: tensile strength and shear strength.
The air-tightness performance of the curtain wall should meet the grade requirements specified in the design. When the curtain wall area is greater than or % of the building exterior wall area, materials and accessories should be extracted on site, and test pieces should be installed and produced in the testing laboratory for air tightness performance testing (the air tightness testing test pieces should include typical units of the curtain wall, typical joints, typical possible Open part), the test piece should be designed according to the curtain wall engineering construction drawings. The design of the specimen should be approved and confirmed by the project supervisory engineer of the construction design unit, and the test results should meet the grade requirements specified in the design.
