Description
Technical Field
[0001] The utility model relates to the technical field of factory building fire safety, in particular to a front coal bunker main factory building structure for facilitating fire fighting and rescue. Background Art
[0002] The main plant building is over 24m high and is considered a high-rise building. According to the requirements of the Code for Fire Protection Design of Buildings and the Fire Protection Standard for Thermal Power Plants and Substations, the fire rescue design of the main plant building requires the installation of two parts: a rescue hatch and a fire climbing site. However, during the actual design process, we found that the requirements in the code lacked sufficient pertinence, so we proposed a more reasonable fire rescue solution.
[0003] In actual fire accidents, most fires in buildings have grown to a relatively large scale when the fire brigade arrives. It is sometimes difficult to directly approach the fire source from the stairwell. However, when extinguishing a fire, the fire can only be effectively extinguished by directly applying the fire extinguishing agent to the fire source or burning combustibles. Therefore, the "Code for Fire Protection Design of Buildings" stipulates that the exterior walls of factories, warehouses, and public buildings should be equipped with windows for fire rescue personnel to enter at appropriate locations on each floor, and obvious signs that can be easily identified outdoors should be set. The distance between rescue openings should not be greater than 20m.
[0004] For high-rise buildings, rescue operations require the use of fire-fighting climbing vehicles to enter these rescue openings, so it is necessary to design a fire truck climbing operation site, and at the same time, the location of the rescue opening should correspond to the fire truck climbing operation site. The "Design Fire Protection Standards for Thermal Power Plants and Substations" stipulates that the main plant should have at least one fire truck climbing operation site at the fixed end and the expansion end, and a fire truck climbing operation site should be arranged between every two units on the outside of the long side wall of the steam turbine room.
[0005] Although the roof height of the steam engine room exceeds 24m, it is a high-rise building, but the workshop actually has only three floors, and the building elevation of the highest floor is generally within 20m. Firefighters can use ordinary fire trucks or climbing ladders to enter the rescue windows on the three facades of the steam engine room without using fire climbing trucks. The distance between the rescue windows can also be controlled within 20m.
[0006] There are many floors in the coal bunker room, and the building elevation of the highest floor is often around 40m. Firefighters must use fire climbing vehicles to enter the rescue windows on the corresponding floors from the outside. The length of the coal bunker room of the million-level group is often 180m or more. If the rescue entrance can only be entered from both ends of the coal bunker room, the distance of the fire rescue entrance is far beyond the 20m distance recommended in the specification. At the fire scene, the firefighters run within 80m holding the water pipe. Too long a running distance will cause difficulties for rescue.
[0007] Therefore, a front coal bunker main building structure is designed to facilitate firefighting and rescue in order to overcome the above problems. Utility Model Content
