Discussion on the combination layout of sprinklers and permeability ceiling in passenger railway station
The layout of sprinklers in the permeability ceiling place of the passenger railway station should not only meet the requirements of the Code for design of sprinkler systems(GB 50084-2017),but also respond to the requirements of ensuring the cleanliness and beauty of the ceiling proposed by Detail design of passenger railway station.This paper uses the hydraulic cal-culation area of sprinkler system as the calculation unit,derive the calculation formula of the per-meability rate of various types of the permeability ceiling in the passenger railway station.Then through the technical and economic comparative analysis the hidden installation of four kinds of sprinkler,come to the conclusion that the permeability ceiling place is suitable for using the pend-ant sprinkler to hidden install in the ceiling gap or mesh,and install the manger above the sprin-kler,and take the permeability slat ceiling place as an example,provide the specific installation pattern of sprinklers below the ceiling.The final emphasis,that sprinkler systems design of the passenger railway station public area,should be according to the different ceiling type,calculate the ceiling permeability rate,determine the specific installation of the sprinkler,to ensure that both conform to the ceiling clean and beautiful view requirements.At the same time,should check design flow and average spray intensity andmoisture storage capacity of that sprinkler systems,en-sure the safety and compliance of the entire sprinkler system.
