Requirements of commercial building code for kitchen floor height

Story height: the vertical distance between upper and lower floors or between floors and the ground. That is, the height of a one-story house. Clear height: the vertical distance between the floor or ground and the bottom of the upper floor or ceiling. The relationship between clear height and floor height can be expressed by formula: clear height = floor height-floor thickness. That is, the difference between floor height and floor thickness is called "clear height". Code for Residential Design (GB50096- 19993.6.4) stipulates that the indoor clear height of kitchen and bathroom should not be less than 2.20 m. 3.6.4 Description: The flow of people in kitchen and bathroom is small, and the indoor clear height is lower than that in bedroom and living room (hall). However, the relevant gas design and installation specifications require that the kitchen be not less than 2.20 m; The requirement of air volume and height of the ventilation opening in the bathroom should not be less than 2.20m m. In addition, from the development of kitchen and bathroom equipment, the indoor clear height below 2.20m is not conducive to the layout of equipment and pipes.
