When designing the aluminum alloy sliding window, the installation and use safety of the sliding window should be considered. When the overlap amount of the window height direction is too large, it will bring difficulties to the installation; if the overlap amount is too small, there will be safety problems, and the window sash will easily come out of the window frame. Therefore, the amount of lap should be selected correctly.
Determination of overlap amount in the height direction: the overlap amount should be selected according to the groove depth of the upper sliding profile, the rail height of the sliding profile, and the height of the window sash pulley. The overlap between the window sash and the upper slide is generally 1 / 2 of the upper chute depth minus 2 ~ 3mm, and 10 mm can be selected. The overlap between the window sash and the sliding is the distance from the groove depth of the pulley to the lower edge of the window sash, which is generally 6-10 mm, and 8 mm can be selected.
In addition, the height of the sliding opening is 4 mm, which can also be used as the drawing depth.
The overlap amount in the width direction should be determined according to the edge sealing profile, hook profile and smooth profile. During the design, the hook and groove of the two window sashes should be completely overlapped.
The aluminum alloy sliding window is divided into two sliding windows, three three equal sliding windows, three four equal sliding windows and four sliding windows. When designing, the width and width of window sash should be within the range of national standard.
When designing the sliding window with fixed window, if the upper and lower grid is divided, the middle upper sliding profile or the middle sliding profile can be used between the fixed window and the sliding window; if the left and right partition is adopted, the fixed edge sealing profile can be used between the fixed window and the sliding window. If it is a high-rise building, it is also necessary to consider whether the thickness series of sliding window meets the requirements of wind pressure strength.
When designing the yarn fan, the lapping amount in the height direction is selected according to half of the groove depth of the yarn rail. The overlap amount in width direction can be selected according to the width of gauze sash not exceeding the width of window sash, and the width size shall not exceed the width of window sash.
