某影剧院公共场所消防安全设计(3)
The auto-spray system adopts the design of wet-type auto-spray fire extinguishing system. In accordance with regulations and rule, this building is regarded as I class of danger categories. This design chooses the layout of nozzle in the form of rectangle, drafting nozzle layout for each room. As for each room, it will make sure the specific location in accordance with the width and length, and the amount of nozzle, and make sure the layout of the hoses.
The design of automatic alarm system is the key link in the design of fire-control in a building, and plays an important role of early alarming and extinguishing fire. It involves the selection of automatic alarm systems type, the choice of fire-detection method, and the decision of fire-detecting equipment, etc. In accordance with the features of business service building, and the height of each floor, the automatic alarm system selects smoke-sensing fire-detecting equipment, and maps out the principle of layout in line with distance between each sensor drew from the spacing maximum curve graph.
The design is mainly made for fire emergency of A class, and few for E class. Fire extinguishers are equipped with ammonium phosphate powders (MF/ABC5) and hands holder. Fire minimum configuration level is 3A,and maximum protection distance of hands holder is 15 meters. Type of quantity of fire extinguishers used depends on protected area square.
Summary of the design of this type of public places fire safety hazards focus and types of accidents that may occur as well as regional fire system design. During design, I found all respects with fire-related information, and access to relevant design specifications and design manuals, finally completed the construction of the fire in public buildings design through the libraries.
Key words: public building; fire protection system design; analysis of fire hazards; smoke control system; hydrant system; automatic fire alarm system; configuration of fire extinguisher
