What is the required floor height of a restaurant building kitchen?

Let’s calculate it.

Article 3.3.4 of the "Catering Building Design Code" stipulates that the indoor clear height of the kitchen and catering production room should not be less than 3 meters.

Based on the conventional column spacing of 8.4 meters for public buildings, the beam height is 600 millimeters, which cannot be any smaller.

Assume that there is a dining room above the kitchen, and the floor is made of floor tiles with a surface thickness of 50 mm (100 mm if there is a cushion).

The air duct is 300 meters high.

The smoke exhaust duct is temporarily considered to be 300 meters high, assuming that the smoke exhaust duct does not intersect with the air duct and does not occupy the space under the beam.

The sprinkler pipe passes through the beam and does not occupy the space under the beam.

The sum of the ceiling, keel and ceiling board is considered to be 50 mm.

Add the above items: 3000 600 50 300 0 0 50=4000 (mm) = 4 (meters)

This does not take into account beams and air ducts, air ducts and suspended ceilings The gap between them, and the kitchen floor is partially raised due to the slope. Therefore, the kitchen floor height is not "too high" considering it is 3.9 meters.
