High-rise hotel fire protection design

Abstact: The design object is a high-rise hotel and the building height is 51。05 meters。 The design age for use is 50 years。

   The main contents of this design include: fire prevention design of total floor of high-rise hotel; Safety evacuation design; Design of fire extinguishers; Design of hydrant feed water system; Automatic sprinkler system Smoke prevention design; Automatic alarm system design。

   The design object is a type 2 public building, with a fire resistance rating of two。 The design object is more than 13 meters away from the surrounding buildings, satisfying the fire space between any buildings。

  Building plane refractory design according to the building structure and purpose, and the corresponding specification, the design of the project layer on each floor area of not more than 1 to 13 in the specification requirements of 2000 square meters, so each floor on the horizontal direction can be pided into a fire zone。 The basement is pided into three fire zones。

   The safe evacuation route has a clear direction and line, it from room to aisle to front room and stairway。 The first floor has three safe exits。 Design safety evacuation, its evacuation distance meets the specification requirement。 The two staircases are designed for the smoke stairway, and the width of the staircase is 1。2 meters。

  The danger level of the design object is in the middle and critical stage, the fire type is mainly A fire, and there is an E fire。 The project each fire extinguisher the set point is equipped with 1 to 2 with 4 kg of portable ammonium phosphate powder MF/ABC4 fire extinguisher, number of each calculation unit should configure a fire extinguisher is: a total of 15, basement, first floor 6, 6 on the second floor, three layers of six, four to ten layer 6, 11 layer 3, 10 3, on the second floor room with the layer 2, with a total of 47。

  The engineering design of the outdoor fire hydrant system, set up two outdoor hydrant on the ground, look-up table to determine indoor fire hydrant water supply, fire hydrant protection radius of 28。1 m, the distance of 25。63 m。 Arrangement for the double row of the ground floor of a fire hydrant, each row of three fire hydrant, fire hydrant layout on each floor above ground for single row, each row of three fire hydrant, each layer of a total of three fire hydrant。 The building's indoor fire hydrant system sets up four pumps。

  Automatic sprinkler system is chosen for the wet automatic sprinkler system。 According to the specification, identify the level I danger level in the middle risk category。 Design using the square nozzle arrangement, determine the most unfavorable point calculated after covering the area of the location and shape of nozzle spray area at the most unfavorable point number 15, covers an area of 163。35 m2。 The total flow rate of the spray system is 22。83 L/s。 The building has a fire water tank with a capacity of 18m3。

  This building take smoke control design of every room, building part all by building external wall to decorate each room above the ground, outside the window area, which can be opened, have enough natural smoke extraction can be used, in this paper, the building adopts the mechanical smoke exhaust design basement, the basement, is pided into nine smoke partitions, among each smoke partition set an exhaust port, the basement exhaust system maximum air volume of 59481。6 cubic meters per hour, staircase winds method for positive pressure air supply system Settings, system air volume in cubic meters per hour。 When the fire occurs, the flue can be discharged in time。
