Window width: the window width generally starts from 0.6m to form a “belt window”.
In addition to being used for passage, the corridor often becomes the carrier of the pipeline.
The door width of public buildings is generally 1m for a single door and 1.2 ~ 1.8m for a double door.
This is a measure to avoid palpitations, dizziness and danger when overlooking.
4.
The specification stipulates that the clear width of the aisle leading to the bedroom and living room in the residence should not be less than 1.0m, which is only the size of one person walking in the right direction and the other person giving way on one side.
The use of “not less than” in this dimension takes into account that in brick concrete buildings, the clearance of 0.24M wall and 1.2m middle distance aisle is only 0.96m, less than 1.0m.
Key words: the height of the door for people to pass through is generally not less than 2m, and no matter how high it is, it should not exceed 2.4m, otherwise there is a sense of emptiness, and the door leaf production needs to be specially strengthened.
2.
In other buildings, it must meet the requirements of fire evacuation.
It should be noted that when calibrating the height of parapet, the structural height of thermal insulation layer and discharge slope shall be deducted.
Key words: aisle 1.
If you want to broaden the field of vision on the flat roof, a metal mesh fence can be added above the 1.0m solid wall to ensure safety.
In order to avoid manual touch, the height should be 2.15m higher than that of ordinary people.
As for the crowded aisle of large public buildings, its width should be determined according to the nature of use and evacuation requirements.
Generally, the long, dark aisle with rooms or walls on both sides should be appropriately wider or handled by changing the width, so as to avoid the long, dark, stuffy and narrow aisle, but it can not be widened without principle, Wasted construction area.
General high-rise buildings try not to set up or close the balcony, which involves many problems such as strong wind, heavy rain and falling objects.
Nowadays, the requirements for building equipment are more common than before.
When the width of the stairwell is greater than 0.20m, the clearance of the vertical bar of the handrail shall not be greater than 0.11M to prevent children from falling.
2.
2.
In addition, when the sill height is lower than 0.8m, protective measures shall be taken.
In addition to the well-known tread and riser dimensions of steps, the width of ladder section, the width of rest platform and the net height of platform downline are also clearly specified in the specification.
Aisle height: the net height of the aisle depends on the building floor height, which is usually not specially considered in the design.
As for the clearance requirements for various vehicles, please refer to the corresponding specifications.
The height of stair handrail (measured from the leading edge of the step) should not be less than 0.90M; The height of outdoor stair handrail shall not be less than 1.05M.
The door for vehicles or equipment to pass through shall be determined according to the specific situation, and its height shall be 0.3 ~ 0.5m higher than that of vehicles or equipment, so as to avoid collision with the door frame due to bumps or equipment needs to be padded with rollers.
In some high-rise buildings, due to the podium, the cooling tower is set on the roof, or there are facilities such as roof tennis courts.
In modern glass curtain walls, the height of the whole glass has exceeded 7.2m, which is no longer within the scope of ordinary windows.
Key words: the door width is generally 0.9 ~ 1m for household door, 0.8 ~ 0.9m for room door, about 0.8m for kitchen door and 0.7 ~ 0.8m for toilet door.
Key words: there are a lot of dimensional data involved in stairs.
It is easy to be ignored that: 1.
Incidentally, the size of “manhole” for maintenance shall not be less than 0.6m × 0.6m。 Key words: window size 1.
Key words: balcony is familiar to everyone, but its railing height should not be less than 1.0m in multi-storey buildings and 1.10 in high-rise buildings.
The width of expressive stairs in public buildings is usually too large, but attention should be paid to the relationship between the setting of handrails and the width of stairs..
The width of the emergency exit for safe evacuation shall be set according to the calculation and specifications (relevant fire protection specifications).
This is a “one-way line”, and generally only one person is allowed to pass through.
Generally, the middle distance between the walls on both sides is 1.5 ~ 2.4m, and then the width is an aisle with other functions, such as recess activities, waiting for treatment, etc.
As for the height of the window, it is determined according to the requirements of daylighting, ventilation and spatial image, but pay attention to the problem of too high stiffness of the window, and add beams or “splicing beams” when necessary.
Therefore, generally, the upper frame is as high as or lower than the ordinary door, and there is a threshold with the same height as the skirting line at the lower side, so the net height does not have to be limited to about 2m and 1.5m.
If necessary for modeling, ventilation and daylighting, waist windows can be added on the door, with a height of 0.4m, but it should not be too high.
As a rule, the net height should be more than 2.2M, especially when there are sagging smoke detector and spray hose on the flat top.
According to the code for design of residential buildings (gbj96-86), its net width should not be less than 0.8m.
The bottom height of window sash opening to public walkway shall not be less than 2.0m.
Therefore, the problem of the clear height of the corridor often appears in front of the designer.
The clear width of the stair landing shall not be less than the width of the ladder section, and shall not be less than 1.10M.
Aisle width: the narrowest aisle should be the aisle leading to the auxiliary room in the residence.
Nowadays, there are many inspection doors for various equipment tube wells in the building, which are not often passed through.
Air pipes, water pipes, electrical and fire-fighting pipelines use the upper space of the corridor as the “corridor”.
The width of the door for pipeline and maintenance is generally 0.6m.
Considering the moving in of modern furniture, the upper limit size is mostly taken today.
Window height: in general residential buildings, the height of the window is 1.5m, plus the height of the windowsill is 0.9m, the window top is 2.4m away from the floor, and there is still a structural height of 0.4m.
It should also be added that the length of the aisle, whether the lighting and other factors have a considerable impact on the width of the aisle.
By the way, the texture of such a low ceiling must be very fine, otherwise there will be a sense of depression.
Also, pay attention to that the window width of the full Bay will cause glare on the horizontal wall, which is not suitable for the classroom and exhibition room.
The ladder width is clearly specified in the residential design specification.
In high-rise buildings, this thickness is often more than 0.3m.
The clear width of the outer walkway of high-rise residential buildings and the aisle of public buildings is generally greater than 1.2m to meet the width of two people in parallel.
Nowadays, it is sometimes encountered that in order to minimize the floor height, the clear height of the walkway is compressed to 2.10m, which is probably the minimum height.
For the door for motor vehicles or equipment, in addition to its own width, a gap of 0.3 ~ 0.5m shall be reserved on each side.
3.
In this case, it is necessary to change the width and width from the plane to avoid both pressure head and monotony.
The door leaf width of double doors or multiple doors should be 0.6 ~ 1.0m.
However, when using the belt window with full width, pay attention to the sound insulation of the left and right adjacent rooms and the sliding range of the sliding window sash.
It is also a way to make the parapet higher than 3.0m.
In public buildings, the height of window sill varies from 1.0 to 1.8m.
We divide the total height of the aisle into the following four parts: ① structural height; ② The height of equipment pipeline is generally about 0.6m, depending on the section and layout of air duct, as well as the arrangement of condensate pipe and automatic sprinkler pipe; ③ The structural height of flat roof is generally 0.05m; ④ Clear height, which is the size that designers should carefully grasp, is one of the important factors determining the floor height.
If it is a building with large volume and large space such as stadiums, exhibition halls and so on, if it is necessary to set a super-scale door, an auxiliary door of conventional size can be added to the door leaf, so that people can pass through when the door does not need to be opened.
The fabrication of the door leaf should be considered if it is wider.
Key words: parapet generally, the parapet of multi-storey buildings is 1.0 ~ 1.20m high, but the parapet of high-rise buildings is at least 1.20m, usually higher than the chest shoulder or even higher than the head, up to 1.50 ~ 1.80m.
