Waterproof seal design
⒈Minimum control index of watertight performance of aluminum alloy doors and windows
The minimum watertightness index of aluminum alloy doors and windows can be taken from the following formula and not less than 150Pa (that is, the watertightness of aluminum alloy doors and windows cannot be lower than the level 2 index):
P=k×μz×μs×wo
In the formula, P: the design value of water tightness (Pa);
wo: basic wind pressure (N/㎡);
μz: wind pressure height variation coefficient;
μs: body shape coefficient, preferably 1.2;
k: coefficient, the value of k is 0.3 in coastal tropical storm and typhoon areas, and 0.25 in other places.
⒉ Door and window structure waterproof design
(1) The principle of isobaric pressure is actively used in the structural design of aluminum alloy doors and windows, which is the most effective way to improve the waterproof and sealing performance of doors and windows.
(2) The overlap between the movable sash and the window frame should not be too small, and the overlap between the movable sash and the window frame of the casement window should not be less than 6mm.
(3) For high-rise buildings, cold areas and areas with high energy-saving requirements, try to adopt the structure of casement doors and windows, and use less or no sliding doors and windows. Since there is a large gap between the sliding sash and the upper and lower slide rails, and the two adjacent sashes are not on the same plane, there is no sealing and pressing force between the two sashes, and only the tops are used for overlapping and lap jointing. There are gaps between the tops, and the sealing effect is very weak, so the waterproof sealing performance of sliding doors and windows is very poor. The casement doors and windows are provided with 2 to 3 sealing rubber strips between the sash and the window frame. After the sash is closed and locked, the sealing rubber strips are pressed very tightly, and the middle cavity is easy to form an isobaric cavity, so it can be Design doors and windows with excellent sealing performance.
⑷The aluminum alloy glass pressing line of the glass for doors and windows should be designed in the indoor direction to avoid water seepage in the fine gap between the glass pressing line and the window frame.
⑸ Push-pull type doors and windows should be designed with a high enough water baffle on the indoor side, otherwise when the outdoor rainwater has a certain pressure, the rainwater will flow into the room through the water baffle.
⑹The upper part of the movable fan of doors and windows should be provided with a water drape, and the lower part should be provided with a drainage hole.
⑺ Combined doors and windows should minimize the exposed joints, because the small gaps cannot be sealed with sealant and leakage occurs. When the exposed seam cannot be avoided due to structural reasons, the two contact surfaces of the profiles at the seam will form a 90° angle, which is convenient for sealing with sealant.
