Fire water supply system design includes the outdoor fire hydrant system and indoor fire hydrant system. Making sure the amount of outdoor fire hydrants and the water supply volume, as for the outside fire hydrant system, the design selects 65mm hydrant, monitor with a 19mm nozzle, and glue-wall hose with 65mm diameter and 20m long. Besides, this design carries out the water-power calculation of full water spout, fire hydrant protective radius, fire hydrant distance, nozzle pressure of monitor, nozzle flow volume of monitor, resistance losses of water hose, required pressure of hydrant’s hole and water tank.
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 II 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 system’s 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 building commercial building 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 a commercial building design through the libraries.
Key words: business service building; fire protection system design; analysis of fire hazards; smoke control system; hydrant system; automatic fire alarm system; configuration of fire extinguisher
