Code of architectural design for nurseries and kindergartens JGJ39-2016 (2019 edition) Notes on amendments 1 General provisions According 1.0.3 to the survey, the scale of nurseries and kindergartens is expanding. Some nurseries and kindergartens have as many classes as (20-30) and are too large, which is not conducive to the management, safety and service quality of nurseries and kindergartens.Therefore, it is suggested that the scale of nurseries and kindergartens should not be too large.According to the results of the survey, this article stipulates the norms of nurseries and kindergartens and the number of classes.The construction scale of nurseries and kindergartens and the number of classes proposed in the norms are suitable for the management of nurseries and kindergartens. This article increases the size of nurseries and the age and number of infants and young children in each class, which is determined on the basis of the recommendations of the State Health and Health Commission. 1.0.5 The architectural design of nurseries and kindergartens involves many aspects and specialties. Except for the need to reiterate the existing standards, this code is no longer repeated. Therefore, in addition to the implementation of this code, it should also comply with the provisions of the current relevant national standards, including the Unified Standard for Civil Architectural Design GB50352, the Code for Fire Protection of Architectural Design GB50016, and Ann.Technical Code for Full Preventive Engineering: GB50348, Standard for Building Lighting Design, GB50033, Standard for Sound Insulation Design of Civil Buildings, GB50118, Standard for Indoor Environmental Pollution Control of Civil Building Engineering, GB50325, Standard for Energy Conservation Design of Residential Buildings in Severe Cold and Cold Areas, JGJ26, Standard for Energy Conservation Design of Residential Buildings in Hot Summer and Cold Winter Areas, JGJ134, and Standard for Residential Construction in HotBuilding Energy Conservation Design Standard JGJ75, etc. 2 Terminology 2.0.5 The living room for children includes the activity unit of the kindergarten class, the multi-functional activity room and the public activity room for the special activities of infants and young children.Infant 2.0.6 The infant life unit is the space in the infant living room for a class of infant kindergartens.Nurseries include breastfeeding classes, small classes and large classes.Kindergarten living unit includes activity room, dormitory, bathroom, clothes and hats storage room, etc. 3Base and General Plane 3.1 Base 3.1.3 Nurseries and kindergartens are located in or near residential areas, which is convenient for parents to pick up and deliver, and their service radius should not be too large.The existing residential areas in the survey are large in scale, but there are no nurseries and kindergartens. Some even have nurseries and kindergartens, whose service radius is too large, and parents'transfer will take a long time.Children's walking time should not be too long, so the service radius of nurseries and kindergartens is stipulated.The revised service radius is 300 m, which is more convenient for infants and young children to receive and deliver, according to GB50180 of Standards for Planning and Design of Urban Residential Areas. 3.2 Total Plane 3.2.2 Nurseries and kindergartens are preschool institutions for children aged 1 to 6 years to carry out intensive care and education.Kids spend most of their time here doing various activities.Because children's body is not yet mature, their physical resistance is weak, and their adaptability to the external environment is poor, it requires nurseries and kindergartens to ensure their safety, hygiene and applicability.Nurseries and kindergartens have many requirements in building layout, room settings, indoor and outdoor environment, which require building closure and surrounding walls.In order to meet these requirements in architectural design, the building is required to be closed and surrounded by walls.In order to meet these requirements in architectural design, it is necessary to set up building bases independently so that buildings are not affected by the outside world.If nurseries, kindergartens and other buildings are built together, it will inevitably interfere with children's living environment, and it is difficult to ensure the safety, hygiene an
