Is the window size of the building the same as the drawing size?
The size of doors and windows in the door and window table of architectural drawings refers to the architectural size of the hole. On the basis of size of the hole, the actual size of doors and windows is subtracted from the installation process size.
Generally speaking, the reality is mainly based on construction drawings. The dimensions of doors and windows are marked as, for example, m 102 1, c 152 1, indicating that the display door is 1.0 m high and 2. 1 m high. Window, width 1.5m, height 2.1m. At the same time, the height of doors and windows is determined according to the story height. The necessary protective height of 0.9 m and the height of beams are generally taken as112 of the span, so the calculated space height is the actual height of windows or the height of doors.
At the same time, the width of doors and windows is also formulated according to the code for building fire protection, and the evacuation width generally needs size of the hole of1.0m. The height shall not be less than 2. 1 m. The window size is determined according to energy saving and window-wall ratio. For example, if the actual bay is 3.3 meters and the height is 3.0 meters, then the height of the window = the actual width of the window according to the limit value of 0.3.
