Should have a refuge floor; (high) 3. Attachments on the roof, such as elevators, stairwells, water tanks, chimneys, etc., may not be included in the height (built) for firefighting; for general areas, the total area does not exceed 25% of the roof area, or the height does not exceed 4m. Within the height of the building (technical); for the urban landscape, the microwave channel must be included in the building height; for the route must be included in the total height, and should be calculated to the highest point of the building including microwave antennas, flagpoles and other components.

2. The architectural technical measures stipulate that the slope roof is the average height from the outdoor design floor to the building eaves and ridge; the flat roof is the outdoor design floor to the height of the building's parapet wall.

(Technology) 2. The height of the roof surface of the underground (semi-underground) room (layer) of the building is not included in the ground floor when the floor is designed for outdoor use (not counting the floor area ratio); when the height is >, it should be included in the ground floor.

(Construction) IV. Calculation of Building Fire Protection Design Layer N The building is a three-dimensional structure that provides space for people to move. The vertical scale reflected by all buildings on the ground is the building height.

A certain height is divided into several layers to form the number of layers in the building.

Building height and number of floors objectively reflect the inherent characteristics of the building. Micro-architectural (architectural WeChat public: tg_wjz) (2) N鈮?0 floors are high-rise (including residential buildings with commercial outlets on the first floor), and 鈥淗igh-rise civil building design fire protection specifications鈥?(high) (1) H鈮?0m is two Class high level.
