What is the turning radius of fire truck?

The first is a saying: 
Turning radius of ordinary fire truck is 9m, take a car turning radius of 12m, a number of special vehicles turning radius is 16 ~ 20m. Therefore, the fire road turning radius = radius of turn ordinary fire engines 9m-3m=6m. 

The second argument: 
The latest "architectural design code for fire protection" (2006-12-01) P263 write a "maximum turning diameter of 24 m; 10 m minimum turning diameter", then the fire truck 
turning radius is 5m ~ 12 meters. 

The third argument: 
Fire road width itself in accordance with regulatory requirements is not less than 4 meters, in order to facilitate the passage of fire vehicles, should be set back to the end of the driveway formula yard, back yard area of ​​not less than 12 meters by 12 meters, is a ring if the lane, the road should be design turning radius, corner radius is 12 meters, calculation, if the road width is 4 meters, the corner is a right angle, the right angle to the top of the arc at the corner is about 10.6 meters. 

The fourth argument: 
1, About fire road  high-rise buildings should be set to four weeks annular fire truck road, lane width of not less than 4m, when the ring set fire road is really difficult, you can set the fire road along the side of the building two long, high-rise housing can be arranged along one long side fire lanes. 
2, the end of the type of fire road, which is generally less than the Enter Site 15×15m. Take a car turning radius of 12m, fire access road within the turning radius available (14m- track width) method checked. 
3, from the fire road and the building's exterior should not be less than 5m. 
4, fire road should be routed pump adapter, outdoor location of fire hydrants, fire water to avoid conflict with the climbing operation. 
  
About climb facade 
1, high-rise tower building 1/4 can be left as the surrounding fire climbing facade, other high-rise buildings should be left at least one long side of the fire climb facade should staircase or household indoor balcony, the main window. 
2, if the climbing surface side of the podium, the building height is not more than 5m, and the depth of not more than 4m still available as a fire climbing surface. 
3, Fire climbing facade should not be set large areas of glass curtain wall. 
      
Take a car on the operation of the site 
1, can be combined with fire road climb venue arrangement, the distance between the building's exterior should not be less than 5m, should edging arranged 8m wide space in its climb climbing surface side. 
2, the above arrangement is indeed difficult, to determine a number of pieces of fire or climb climbing surface sites within its scope. Climbing site area of ​​not less than 15m × 8m (length × width), which point to the outermost edge of the building climbing surface horizontal distance of not more than 15%. 
3, has a ramp climbing venue, the ramp should not exceed 15%. 
4, the use of fire as a municipal road climbing site, its green, overhead lines, tram grid and other facilities shall not affect the fire truck parked and jobs. 

Fifth argument: 
fire lanes 
1, residential multi-storey residential district, the district should set fire road, lane width of not less than 3.5m, the turning radius of not less than 9m. 
2, surrounded by high-rise housing should be provided with an annular fire road, lane width of not less than 4.0m, the turning radius of not less than 12m. When the lane is really difficult to set up the ring, high rise buildings, a class of high-rise residential side should set the fire road along the two long buildings; two types of high-rise residential side can be arranged along a long fire road building. 
3, should be at least two fire road communication with the other lanes. Make-ended channel should be set back to the fire lane or carriage venue. 
Note: Enter multi-storey residential space of not less than 12m × 12m; two types of high-rise residential Enter the site should not be less than 15m × 15m; a class of high-rise residential and high-rise commercial and residential space should not be less than the Enter 18m × 18m. 
4, the housing complex conjoined, a direction along the street when the length exceeds 150m or the total length of more than 220m, shall be provided with communication street 
and the inner courtyard of walkways, clear width of not less than 1.2m (available stairwell), the spacing not more than 80m. 
5, fire road can be combined with green design, but the roadbed should be able to withstand fire load, the road should ensure access for fire engines. 

It should be set to high-rise residential fire truck climbing surface 
1, fire climbing surface length of the high-rise residential tower should not be less than 1/4 the length of the surrounding homes. 
2 high-level modular, fire climbing surface length Corridor residential housing not less than the length of a long side. 
3, the fire climbing surface should be close to residential balconies, windows or communal staircase; commercial and residential building should be within this range are equipped with outlet straight stairwell. 
4, should not set fire climbing surface side of the gate can not open the window, not large areas of glass curtain wall design. 
5, fire climbing surface side of the podium should not be arranged, when arranged podium, its depth should not exceed 4m, height should not affect the fire truck climbing 
rescue. 
6, fire climbing surface side can be used as a fire road climb the fire site, should be set up on both sides of the lane width of not less than 1 m and margins within the same lane elevation compacted ground, lane residential buildings should not be less than 5m, and not more than 12m; when the use of fire as a fire road climb venues have difficulty climbing surface side of the fire can also be combined to set fire road less than a tamping the ground as the fire ascended site, an area of ​​not less than 15m × 8m. 
7, the vertical gradient of climb fire site should be controlled within 8%. 
8, the use of fire as a municipal road climbing site, its green, overhead lines, power grids and other facilities shall not affect the aircraft's fire stops operating.
