"House Design Code" GB 50096-2011

Partial amendments to provisions

Original: 6.4.1 Elevator must be installed in one of the following cases:
1 When the height of the seven-story or above residential or occupant entrance floor from the outdoor design ground exceeds 16m;
2 When the first floor is a six-story or lower dwelling that is used as a shop or other house, the floor height of the entrance floor of the dwelling is more than 16m from the outdoor design ground of the building;
3 When the first floor is a six-story or lower-floor dwelling with overhead or storage space, when the height of the residents' entrance floor from the building's outdoor design ground exceeds 16m;
4 When the top floor is a two-story jump-dwelling house, the jump part does not count the number of floors, and the height of the top-floor entrance floor from the building's outdoor design floor exceeds 16m.

Amended as follows: 6.4.1 An elevator must be installed when the height of the four-storey or above residential or occupant entrance floor from the outdoor design floor exceeds 10m.
The main amendment of this article is to change the number of floors originally set for elevators from "seventh and above" to " fourth and above "; and change the height of the residents' entrance floor from the outdoor design floor, from "When over 16m" is changed to "When over 10m ".
The main background and reasons for the modification of this article are as follows:
1. China has entered an aging society. As the population aging speeds up, it is an indisputable fact that residential elevators are equipped with standards that are too low. Many provinces and cities have proposed new requirements in local standards in accordance with local ageing requirements of ordinary residential buildings. Therefore, the time has come to fully raise the relevant national standards.
2. The "Building Design Code" of China in 1954 stipulated: "Elevator equipment should be provided when the living room is at least five floors or the floor surface is 17 meters above the horizon." However, the 1987 "Code for the Design of Residential Buildings" stipulated that "seven floors (and above) should have elevators." Due to lowered standards and poor implementation, many cities have a large number of dwellings without elevators on the seven, eight, or even nine or ten floors. The inconvenience caused by these houses to urban living is very serious. The 1999 Residential Design Code reaffirmed that "Elevators with a height of more than 16m above the outdoor design floor on the seven-story or above residences or residential entrance floors must be provided with elevators." In 2000, this provision was listed as a mandatory provision and continued Strengthen implementation. Since 2005, not only have no more than seven floors of houses without elevators, but more and more four to six houses also have elevators. At present, raising the standard for residential elevators has become an inevitable choice in history.
3. According to the traditional technical and economic indicators of residential buildings, elevators account for a relatively high proportion of civil construction costs. With the improvement of the overall level of residential equipment and the overall improvement of residential performance and quality, at the same time that the overall price of the residence has increased, the proportion of elevators in the residential sales price has relatively decreased. Raising the standard for residential elevators has become a market economy. Reasonable positioning of standards to meet market needs.
4. Properly raising the standard of residential elevators can effectively guide the new direction of residential design. From the perspective of sustainable housing development in China, the important principle of residential design is land intensive use. Proposing that four or more floors of houses have elevators is not the same as encouraging the construction of four to six floors of houses. In the 1980s and 1990s, the standard implemented in China was "seven floors (including above) should be equipped with elevators". During that period, there were very few residential houses with elevators on the seventh to ninth floors. Therefore, the purpose of the amendment of this regulation should be clearly defined as strictly restricting the construction of four-storey or more houses without elevators.

Original text: 6.4.2 For the twelfth floor and above, there should be no less than two elevators in each building, one of which should be an elevator that can accommodate a stretcher.

Amended as: 6.4.2 For houses with 12 floors or more, there should be no less than two elevators per unit, and one of them should be equipped with a stretcher. An elevator that can accommodate a stretcher should meet the following architectural design parameters:
1. The hoistway net size ≥2.20m × 2.20m;
2. The net size of the short side of the car ≥ 1.50m, and the net size of the long side ≥ 1.60m;
3. The clear width of the elevator door ≥0.90m;
4. The minimum size of the chamfered stretcher is 1.80m × 0.45m;
5. The depth of the waiting hall is ≥ 1.80m.

After revising the minimum number of floors for elevators in Article 6.4.1, the requirements for installing two elevators in this Article remain at “twelfth floor and above”. The point is to change the "setting per building" to "setting per unit". The amendment of this article also cancelled the provisions of Articles 6.4.3 and 6.4.4 on the establishment of contact corridors. In the 2011 version of the article description, it has been proposed that "in practice, the design of the contact gallery will bring problems such as line of sight interference, safety precautions, and loss of natural ventilation and direct lighting in some kitchens. Although this method of setting an elevator is more economical, But it's low level. So the ideal solution is to have two elevators, and one of them can accommodate a stretcher. "
This modification proposes architectural design parameters that can accommodate stretcher elevators. The justification of these parameters is as follows: The research group of “Research on the Standard for the Capacity of Stretchers in Residential Buildings” has found that there is no uniform standard for stretchers (cars) used in emergency centers in various places. , Can not be directly used as a parameter of residential design. Therefore, it is necessary to determine the minimum parameters of a practical first aid stretcher. The research conclusion of the subject is that the stretcher used for first aid in the house should be modified to a chamfered stretcher based on the size of the shovel stretcher. The parameters of the chamfered stretcher are: the total size of the stretcher: 1.80m × 0.45m, 0.38m away from the two ends of the stretcher, and the handles at both ends shrink to 0.2m wide (pictured). This size meets the minimum lying size of the human body. , Covering 95% of China's human height. According to the parameters of the emergency stretcher, it was determined that the minimum size of a stretcher elevator car that can be accommodated in an ordinary house is 1.50m × 1.60m, and a diagonal stretcher car can be placed using a diagonal line. The 1.50m × 1.60m car is widely adapted to the national standard 1000kg model. In this way, the cost of new and remodeled houses is small and easy to implement. At the same time, it is required to leave an appropriate margin for the elevator shaft width, with a net size of not less than 2.20m × 2.20m; the clear width of the door opening of the elevator door is not less than 0.90m, which is convenient for the stretcher car to enter and exit.
In order to further ensure the efficiency of rescue and improve the ability to adapt to more types of stretchers, conditional dwellings can consider using other elevator models with conditions for accommodating stretchers. According to the current national standards of elevator main parameters and the types There are relevant specifications and setting requirements in Dimensions GB / T 7025.1.


1.80m chamfered stretcher can enter the car


National standard 1000kg square car shaft size 2.15m × 2.30m
