Hanging curtain wall stone: selection and calculation of pendants

Hanging curtain wall stone is a complex project, and many factors need to be considered. This paper will introduce the selection and calculation method of pendants to help readers better understand this project.

Pendant quantity calculation

Only 4 pendants (size 1000* 1000mm) are needed per square meter of stone. If you choose a small stone, you need to calculate it accurately in square meters.

Hanging type

Pendants vary in size, and commonly used ones are pick pendants, T pendants, SE combination pendants and stainless steel double hook pendants. However, only aluminum alloy pendants are allowed in Shanghai market, and the regulations in other cities are not clear.

Pendant size

The length, width and thickness of these pendants are determined according to the requirements of drawings, and the length range is about 50- 120mm.

Strength and rigidity of pendants

Ensure that the strength and stiffness of the horizontal and vertical keels meet the design and calculation requirements, and also consider the quality and height of A/B glue.

Specification requirements

According to the Technical Specification for Metal and Stone Curtain Wall Engineering (JGJl33-200 1), the thickness of stone is not less than 25mm, and the area of a single stone is not more than1.5m2. Stainless steel pendants are recommended. At the same time, angle steel connectors, bolts, covered electrode, structural adhesive and other materials must have certificates of conformity and inspection reports.
