High efficiency filter air outlet, lamps, fire extinguishers, etc. shall be installed under the ceiling. All kinds of pipes need to be hidden in the ceiling, so the ceiling is the key part of the indoor decoration of the clean operating room. The ceiling should be made of light steel keel and large panel material (the main board used for the wall can be used as the ceiling panel, see above for details). The vibration of air duct has a great influence on the ceiling, so the control of ceiling vibration is more important than the control of material surface hardness. The materials covering the ceiling shall be filled with sealant or sealed in layers to form a whole, so as to prevent the dust in the upper space of the ceiling from polluting the air flow of the clean operating room through the gap.
In addition, there is a method of hard ceiling, that is, it is directly decorated in accordance with the requirements of cleanliness in the reinforced concrete floor, which is more suitable for the application in the construction projects with lower height. For example, in the clean operating room of 301 Hospital of the PLA, the hard top plate is used, and the hard rubber facing is added under the reinforced concrete roof (on the cast-in-place reinforced concrete floor, as a template, the bottom plate is placed). The features of the hardtop method are high strength, convenient installation and maintenance, but the air supply outlet and lamps need to be punched during installation, so the construction is relatively complex and difficult to replace.
Clean the internal (external) corners between the wall and flat top, between the wall and the ground, and between different walls and walls in the operating room, and make a small fillet structure (R ≥ 50mm) to avoid dust accumulation and facilitate cleaning. There are many clean operating room walls and flat roofs, walls and walls intersect by inclined plate connection, which is more conducive to reduce dust accumulation and eliminate the air vortex area.
The above is a detailed introduction of the requirements of the decoration of the operating room for the ceiling materials of the operating room. For more information, please click http://www.sdyhrs.com
