The automatic sprinkler system is the most effective automatic indoor fire extinguishing system,and sprinkler layout spacing is an important design parameter.In recent years,with the development of Building Information Model(BIM)technology,automatic verification based on BIM has also become a development trend.In this context,this article studies a BIM based algorithm for checking the spacing of a rectangular layout of upright and pendent sprinklers.By extracting model information,the model sprinklers are grouped and sorted according to the straight lines parallel and perpendicular to the water distribution pipe,and two special cases are considered for splitting,the sprinkler spacing can be calculated.Meanwhile,by testing the algorithm with an actual project model containing 2535 sprinklers,non-compliant sprinkler spacing can be calculated and located within 35 seconds,and the efficiency and calculation accuracy meet the requirements.
