GB 50243-2016 第6.2.2条
| **** | Duct connections must not be installed within walls or floor slabs, and supports and hangers must not be located at air outlets, valves, access doors, or automatic control mechanisms; anti-condensation-bridge measures shall be provided between hanger rods and ducts. **(In hotel fit-out projects, the space above suspended ceilings is complex; this clause prevents difficulties in later maintenance and condensation issues.)** |
