Glass curtain wall refers to the supporting structure system relative to the main structure, which has a certain displacement capacity, does not share the main structure by the role of the building envelope or decorative structure. It is a beautiful and novel building wall decoration method. Like other projects, glass curtain walls also need to do some testing, such as wind pressure deformation performance, airtight performance and watertight performance. If necessary, it can increase the plane deformation performance and other performance testing, but also including curtain wall insulation performance testing.
Angle steel and channel steel do not need to be retested. The materials to be retested in curtain wall construction include: peel strength of aluminum plastic composite board, bending strength of stone, freeze-thaw resistance of stone in cold area, radioactivity of granite for indoor use, Shore hardness of structural adhesive for curtain wall, Tensile bonding strength under standard conditions, the pollution of stone sealant and curtain wall structural sealant, the compatibility of weather-resistant sealant and its contact materials and peel bonding test, etc.
Among the materials that need to be reinspected, at least one group of samples shall be taken from the same type and variety of materials produced by the same curtain wall suppliers for reinspection. If otherwise agreed in the contract, the reinspection shall be carried out according to the contract.
Glass curtain wall need to do field experiments are: post-embedded parts of the field pull test, silicone structure sealant peel test, water test, etc.; If the use of two-component silicone structure sealant, it should also do the mixing test and pull test, the same type can do a group.
The same design, materials, technology and construction conditions of the curtain wall project every 500-1000 square meters for an inspection batch, less than 500 square meters should be divided into an inspection batch; There shall be at least one spot check per 100 square meters for each inspection lot, and each spot shall not be less than 10 square meters. The discontinuous curtain wall works of the same unit shall be divided into separate inspection batches.
For the curtain wall with irregular shape or special requirement, the division of inspection lot and the inspection quantity of each inspection lot shall be determined by the supervision unit, the construction unit and the construction unit through consultation according to the structure, technological characteristics and the scale of the curtain wall project. All we can do is to ensure the quality of the glasss curtain wall.
