EnglishFireproof glass window analysis: opening standard and spacing of exterior windows
How big is the exterior window?
There are two common failure cases in window planning: 1. The window is too small; 2. The window is too big.
1. Open fan too small
The result is poor ventilation, neither suitable for living; The problem that the window opening fan is too small is relatively simple to deal with. Various planning standards have provisions on the small value of the ventilation opening area of the residence.
A bedroom of about 12 ㎡ with a 600mm fan × 1000mm fan can meet the ventilation requirements; A living room of about 20 ㎡ with two 600mm fans × 1000mm can be met by opening the fan; There is a 600mm open toilet with an area of 4 ㎡ × 600mm open the fan; The ventilation requirements of the kitchen are higher. There is a 600mm fan in the kitchen with an area of about 5 ~ 6 m2 × 1000mm open fan can also meet the requirements.
Attention: some cities have issued local standards applicable to the region. For example, Shenzhen, Nanning and other cities stipulate that the opening area of doors and windows is not less than 8% of the room area. In the engineering planning of these cities, we should pay attention to complying with these standards.
2. Open fan too large
As a result, it is inconvenient to open, or even affect the operation when opening and closing the window.
Opening leaf of casement window: the width should not be greater than 700, less than 500, and should be about 600; The height should not be greater than 1400 and less than 900, and should be 1000-1200; When selecting too large opening fan (too wide or too high), especially when opening outside, carefully consider the convenience and of opening.
When we pay attention to the problem of too large windows, we often only pay attention to the width. In fact, the height is also very "dead". For general external casement windows, when the sill height is certain, the higher the sash is, the higher the direction of opening the handle will be. During the window opening action of "arm extension → body bending", the height that can be reached by human hands shows a downward trend.
Therefore, the window sash is too high and the handle is too high, which will increase the inconvenience of operation. For ordinary people with a height of 1.6 ~ 1.7m, the arm extension height is about 1.4 ~ 1.5m. According to the general window sill height of 0.9m, 1.0 ~ 1.2m is the reasonable height to open the sash.
In the first floor residence project, the selection of flat opening inner inverted window can improve the value of the product from the perspective of humanized planning.
Conclusion: the residential door and window is a seemingly simple product, but because it is closely related to the long-term use of the broad audience, every detail needs to be carefully considered.
