How much area of the restaurant needs to be equipped with fire sprinklers?

More than 300 square meters need to be equipped with fire sprinklers.

Generally, only commercial, office, super high-rise, and public buildings need to install fire sprinklers indoors. However, if the fire inspection department considers that the residential design of the building exceeds the standard (e.g. the total height of the floor exceeds 100 meters, the commercial area of the first and second floors exceeds 300 square meters, etc.), the developer must install fire sprinklers for each household.

According to the Code for Fire Protection Design of High-rise Civil Buildings (2005 Edition) (GB50045-95), if it is a pure residence, there is no need to install fire sprinklers indoors; If the upper floor is a residential ground floor for commercial, it does not need to be installed inside the residence; But if it is a serviced apartment, then it must be installed in every house.

Each 10 20 square meters of the range is arranged with a sprinkler head. The design principle of the fire sprinkler system is to determine the number and type of sprinkler heads according to the area of the place of use and the object of fire protection.

Wet systems can be used in buildings and places where the ambient temperature is not lower than 4 and not higher than 70 (except for buildings and places where water cannot be extinguished). When the system is applied locally, it is suitable for the area that needs local protection in the light hazard or medium hazard level in the civil building where the maximum indoor clearance height does not exceed 8m and the total construction area does not exceed 1000.

More than 200 square meters.

1. The drooping sprinkler is the most widely used sprinkler, which is installed on the water supply branch pipe by sagging, and the shape of the sprinkler is a parabolic shape, spraying 80 100% of the total water volume to the ground. To protect the room with a suspended ceiling, a sprinkler head should be arranged under the ceiling, and a drooping sprinkler head or a ceiling-type sprinkler head should be used.

2. The upright sprinkler head is installed upright on the water supply branch pipe, and the sprinkling shape is a parabolic shape, and 80 100% of the total amount of water is sprayed downward, and at the same time, the upright sprinkler head is also partially sprayed to the ceiling, which is suitable for installation in places with more moving objects and easy to impact, such as warehouses, and can also be concealed in the roof of the room ceiling mezzanine to protect the boron of the ceiling with more flammable materials. (In places where the ceiling is not made, when the water distribution branch pipe is arranged under the beam, the upright type should be used.) For areas that are susceptible to collisions, a sprinkler head with a protective cover or a ceiling-type sprinkler should be used).

3. The ordinary sprinkler head can be installed directly, or it can be installed on the sprinkler pipe network, spraying 40%-60% of the total water volume downward, and spraying a larger part to the ceiling. It is suitable for restaurants, shops, warehouses, underground garages and other places. (Less common type).

4. The side wall type sprinkler is installed against the wall, which is suitable for installation in places where the space pipe is difficult, and is mainly used in the light and dangerous parts of buildings such as offices, halls, lounges, corridors, guest side wall sprinkler head rooms, etc. The roof is a light hazard and medium hazard class I room and office with a horizontal plane, and a side wall type sprinkler can be used.

Extended information: The working principle of the fire sprinkler system: 1. Closed fire sprinkler system:

Usually the roof fire water tank is filled with water, when a fire occurs, the sprinkler head is prepared to melt after the temperature reaches a certain temperature (generally 68 °C), the water in the pipe is automatically sprayed out under the action of the water pressure of the fire water tank, at this time, the wet report Wang Roll false alarm valve is automatically opened, the pressure switch in the valve is automatically opened, and the pressure switch has a signal line and the fire pump is interlocked, and the pump will start automatically. 2. Open fire sprinkler system: the system is equipped with a smoke detector to detect the smoke, when the smoke reaches a certain concentration, the smoke detector alarms, and the host confirms that it is fed back to the sound and light alarm action, and the sound or flashing lights warn people, and the linkage smoke exhaust fan is started to start the smoke exhaust, and the solenoid valve of the rain deer valve is opened at the same time, and the water is sprayed directly by the open sprinkler head in the linkage spray pump.

In both cases, a sprinkler system needs to be set up. One is that the hotel is in the podium or outlet room of the high-rise building or high-rise residential area, or the building itself is equipped with an automatic sprinkler system, then the hotel must continue to improve the sprinkler system. Another situation is that the building area of the hotel is more than 3,000 square meters or the area of the ground is more than 1,500 square meters, and the sprinkler system needs to be installed.
