What are the specifications of doors and windows in the building? I hope to be specific. . .

3.9. 1 When the height of the window sill outside the window is less than 0.90m from the floor and ground, there should be protective facilities. When there is a balcony or platform outside the window, there is no such restriction. The clear height of the window sill or the height of the protective railing should be calculated from the treadable surface to ensure that the clear height is 0.90 meters.

3.9.2 Outside windows and balcony doors on the ground floor, doors and windows with lower edges less than 2m and close to corridors or public owners' roofs should be well protected.

3.9.3 For windows facing corridors or notches, line-of-sight interference should be avoided. The window sash leading to the corridor should not hinder the traffic.

3.9.4 Security doors should be used for residential doors. Doors that open outward should not hinder traffic.

3.9.5 The minimum size of the door of each part shall comply with the provisions in Table 3.9.5.

Clause Description 3.9 Doors and Windows

3.9. 1 There is no outer window sill adjacent to the balcony or platform. If the clear height from the ground is low, children are prone to fall accidents. This article requires that protective measures should be taken when the windowsill is below 0.90m from the ground. The effective protective height should ensure the clear height of 0.90m, and the treadable surface which is easy to cause unconscious climbing, such as countertops and transverse railings below 0.45m from the floor (ground) surface, should not be included in the clear height of the window sill.

3.9.2 From the point of view of safety precautions and satisfying residents' sense of security, the external windows and balcony doors of the ground floor houses should have certain defensive measures. Doors and windows adjacent to corridors or public roofs are also the key parts of safety precautions, and defensive measures should be taken.

3.9.3 Privacy requirements in residential life have become one of the important requirements for residential use, and windows with notches and facing the corridor in residential buildings often cause strong dissatisfaction among residents due to improper design. This article requires taking measures to avoid line-of-sight interference, such as setting fixed and bright windows and using embossed glass to block the line of sight of people in the corridor.

For the window facing the corridor, the sash should not open to the corridor, otherwise a certain height should be guaranteed or the width of the corridor should be increased to avoid obstructing traffic.

3.9.4 Generally, residential doors designed in the past have no safety defense measures, and are generally modified or installed by residents as safety doors. This article requires that the security door should be adopted in the design, which integrates various functions such as heat preservation, theft prevention, fire prevention and sound insulation into one door. Generally, the door of a house always opens inward, which can avoid obstructing the passage of the stairwell. This article stipulates that when the door opens outward, it should not hinder the traffic. Generally, measures such as increasing the landing of stairs, setting large and small doors and setting notches at the entrance can be taken to ensure safe evacuation.

3.9.5 The minimum size of the door opening of each part of the house shall be put forward according to the minimum standards required for use. When the material structure of the door is too thick or has special requirements, room should be left.
