新规范下“地下车库+地上高层公建”组合建筑消防水量计算

Calculation Methods of the Design Water Consumption of the “Underground Garage + High-rise Public Building”for Fire Protection Under the New Codes

消防设计中不能死抠规范条文,要根据规范的适用性和优先级来总体把握,合理设计。在保障安全的前提下,消防设计还要做到经济适用,不要人为放大设计参数。对于"地下车库+地上高层公建"组合建筑的消防水量计算,应将地下车库、地上公建两部分拆开计算。地下汽车库计算按照《汽车库、修车库、停车场设计防火规范》(GB 50067—2014)取值,地上公建计算按《消防给水及消火栓系统技术规范》(GB 50974—2014)取值,取二者中的大值作为本建筑的消防总水量。

In the process of fire-extinguishing system design, it is more important to make an overall plan and appropriate design method in accordance with the applicability and priorities of codes than to copy the provisions of the code directly. Under the premise of security, the design parameters of extinguishing system ought to be economically feasible, not to be enlarged. For the combination building of underground garage and high-rise public building, the process of determination of design water demand of the ground and the underground ought to be separated. The design water demand of the underground garage is based on the Code for Fire Protection Design of Garage, Motor Repair Shop and Parking Area （ GB 50067 -2014） ; the design water demand of the ground public building is based on the Technical Code for Fire Protection Water Supply and Hydrant System （GB 50974 -2014）. The maximum water demand between the two data above should be taken as the design water demand of the combined building.
