Description

Technical Field

[0001] The utility model relates to the field of bridge frame wall penetration, in particular to a bridge frame wall penetration device for cross-level rooms. Background Art

[0002] At present, the core production areas of most pharmaceutical factories need to achieve effective isolation and distinction between core production and functional technology (black and white areas) or because the production lines of bioengineering equipment are large, some equipment spans several clean rooms. Since the control systems of pharmaceutical equipment are relatively complex, that is, a large number of cables and air pipes need to be controlled across rooms or ceilings to achieve system integrity. At present, bridges or wire pipes are usually used to directly open holes through walls. Since the inside of the bridge or wire pipe is not a sealed device, dozens of cables or air pipes are laid in the bridge and wire pipe. Due to the difference in environmental levels and pressure differences in the rooms on both sides, the bridge or wire pipe has a tendency to cross the hall, resulting in the pressure difference in the clean room being difficult to control, clean environment pollution emerging in an endless stream, the risk of leakage in toxic areas remaining, and the risk of GMP management inspection being uncontrollable. These factors have caused certain troubles and impacts on the quality control of pharmaceutical production of pharmaceutical companies, especially the occurrence of unexplained pollution, pressure difference alarms, toxic leaks, etc. Driven by the pursuit of ever-improving quality, more pharmaceutical companies are requiring the elimination of cable tray or conduit leakage through walls during the installation phase. Currently, there's no perfect solution. Filling cable trays or conduits with fireproofing mortar or polyurethane provides only nominal sealing, but actual leaks persist between the gaps between cables and air pipes within the cable trays and conduits, failing to fundamentally address the problem. Therefore, a new technical solution is needed. Utility Model Content
