When designing insulated doors and windows, consideration should be given to the installation and use of doors and windows. When the amount of overlap in the height direction of the window is too large, it will cause difficulties in installation; if the amount of overlap is too small, there are also problems in use, and the sash is easily detached from the window frame. Therefore, the amount of overlap should be selected correctly.
Determination of the overlap amount in the height direction: The overlap amount should be selected according to the groove depth of the sliding profile, the track height of the sliding profile, and the height of the sash pulley. The overlap between the sash and the upper slide is generally 1/2 of the depth of the upper chute minus 2 ~ 3mm, and 10 mm can be selected. The overlap between the sash and the slide is the distance from the groove depth of the pulley to the bottom of the sash, which is generally 6 ~ 10 mm, and 8mm is optional.
In addition, you can also use the size of the inner opening in the height direction of the push-pull frame, add the depth of the upper chute, and subtract 4-6 mm to determine the height of the push-pull fan.
The overlap amount in the width direction should be determined according to the side seal profile, hook profile and light profile. When designing, the hooks of the two sashes should overlap.
Insulated doors and windows are divided into two sliding windows, three three-division sliding windows, three four-division sliding windows, four sliding windows and so on. When designing, the width and height dimensions of the sash should be within the allowable range.
When designing a sliding window with a fixed window, if it is a vertical partition, the sliding window can be used as a middle-upper sliding profile or a sliding window; if it is a left-right partition, a fixed window and a sliding window can be fixed. Edge seal profiles. If it is a high-rise building, it is also necessary to consider whether the thickness series of the sliding window can meet the wind pressure strength requirements.
When designing the yarn fan, the overlap in the height direction is selected according to one-half of the groove depth of the yarn rail. The overlap amount in the width direction can be selected according to the width of the screen fan not exceeding the window fan width, and the width dimension should not exceed the window fan width.
