Chapter I Basic Principles and Concepts
1. Basic Concepts:
1. Dining places belong to catering buildings, which are divided into four categories according to their management methods, catering methods and service characteristics. Catering buildings include restaurants, fast food restaurants, beverage shops, canteens and cafeterias. See the appendix at the end of the article for the classification concepts.
2. According to the functional division, dining places are mainly divided into dining area, kitchen and auxiliary area (warehouse, etc.).
3. Catering buildings can be divided into super-large, large, medium and small according to the building scale, and shall comply with the provisions in Tables 1.1.4-1 and 1.1.4-2.
note: the building area in the table refers to the building area of the areas directly or indirectly related to food production and supply, including dining area, kitchen area and auxiliary area.
Note: The canteen is divided into different sizes according to the number of people served. The number of people served in the canteen refers to the number of all diners served in the canteen during the dining period.
2. Basic principles:
1. Dining places have their specific functional requirements, and their building fire protection requirements and the setting of fire protection facilities should meet the requirements of Code for Fire Protection Design of Buildings, Standard for Design of Catering Buildings and the corresponding system technical specifications and standards.
2. Dining places include single catering buildings, and can also be attached to hotels, businesses, offices and other public buildings.
3. For catering establishments attached to hotels, businesses, offices and other public buildings, the architectural design of other parts shall conform to the relevant national standards except the catering part.
4. Take-out and group dining distribution can be regarded as a dining place without dining space, which can be designed according to the design requirements of the kitchen of the dining place.
5. Dining places are crowded places, among which dining places with entertainment functions belong to public entertainment places (3.1 and 3.2). See: differences and concepts: crowded places? Public gathering place? * * * public places of entertainment.
6. The auxiliary functional places such as offices and shops attached to the dining place for personal use do not affect the nature of the dining place.
7. Restaurants with karaoke function belong to song-and-dance entertainment venues (5.4.9). For details, please refer to: Song-and-dance entertainment venues-requirements for building fire prevention and fire control facilities!
8. For catering buildings attached to commercial buildings, the division of fire protection zones and the calculation of safe evacuation numbers shall be carried out according to the relevant provisions of commercial buildings in the current national standard "Code for Fire Protection Design of Buildings" GB51116. (4.1.3)
Note: When a restaurant is set up in the business hall, it is no longer a simple store business hall place, and the building area of its fire zone needs to be divided according to the requirements of fire zones of other functions of civil buildings (the maximum allowable building area of each fire zone is not suitable for the store business hall place mentioned in 5.3.4 of the Building Regulations).
