- Abstract:
- The arrangement of sprinkler in automatic sprinkler system directly affects the fire extinguishing effect. When there is no suspended ceiling, the arrangement of sprinkler is affected by the form and height of structural beam. Different sprinkler arrangements can be selected according to the parameters such as structure types, column network span and net height of the beam under the plate in engineering projects. The principle and procedure of the arrangement of sprinkler among structural beams were described, and the arrangement of sprinkler among beams and the applicable scope under different structural types were drawn and summarized. In a fire compartment with cross-laid single-girder structure, the technical and economic differences between standard sprinkler arrangement and sprinkler arrangement with expanded coverage area were compared, which was convenient for designers to choose quickly through schematic drawings and tables, reduce the workload of water supply and drainage design and guide the construction and installation. The engineering cost of automatic sprinkler system can be reduced by optimizing the arrangement of pipes and sprinklers.
