Effective method for fire prevention of high-rise steel structure building
The invention provides an effective method for fire prevention of a high-rise steel structure building, and relates to the technical field of building fire prevention, a fireproof spraying pipe is installed along the axis of a stress component of a steel structure frame, and the fireproof spraying pipe is installed between the stress component and a fireproof heat insulation plate outside the stress component. A pipeline spray cooling system for directly spraying water to a stressed component of a steel structure frame in a steel structure high-rise building is additionally arranged. When a fire alarm occurs, the system is started, water is directly sprayed to the surface of a stress component beam column of the steel structure frame for cooling, it is ensured that the temperature of the stress component beam column of the steel structure frame does not increase to the temperature at which bearing capacity is lost in the fire disaster process, and therefore it is ensured that a high-rise steel structure building does not collapse when the fire disaster occurs; the safety of the high-rise steel structure building is improved when a fire occurs, and the fireproof problem of the high-rise steel structure building is simply and effectively solved.
本发明提供一种高层钢结构建筑防火的有效方法，涉及建筑防火技术领域，沿钢结构框架的受力构件的轴线安装防火喷淋管，防火喷淋管安装在受力构件与受力构件外部的防火隔热板之间。通过增加对钢结构高层建筑中的钢结构框架的受力构件直接喷水的管道喷淋冷却系统。在出现火警时启动该系统，直接向钢结构框架的受力构件梁柱表面喷水降温，确保钢结构框架的受力构件梁柱的温度在发生火灾的过程中不会增高到失去承载力的温度，从而保证了高层钢结构建筑物在火灾发生时不会坍塌，提高了高层钢结构建筑物在火灾发生时的安全性，简单有效地解决了高层钢结构建筑的防火的难题。
