Scope
GB/T 37267-2018 is the English-translated version of 建筑抗震支吊架通用技术条件.
GB/T 37267-2018 is the Chinese general specification for seismic supports and hangers that hold building services in place during an earthquake.
It applies to the design, manufacture and inspection of seismic bracing for water supply and drainage, heating, ventilation and air conditioning, electrical, gas and fire-fighting systems in areas with a seismic fortification intensity of 6 to 9 degrees.
It defines the seismic support hanger as an assembly of anchors, reinforced hanger rods, seismic connectors and bracing fixed to the structure, and distinguishes lateral bracing.
It sets out the general requirements, product requirements, test methods, inspection rules, and marking, packaging, transport and storage. Informative annexes show the structural types of supports and hangers, seismic connection members and pipe connection members. It was issued on 28 December 2018 and has applied since 1 November 2019.
