[China Aluminum Network] aluminum alloy doors and windows leaking water prevention measures: 1. When installing the aluminum window, pay attention to the level of the head cap material, tilt it outward slightly to avoid pouring water. 2. The window sill is cast with fine stone lintel (100mm thick) and anchored into the length of one brick on both sides of the wall, and is made to pick up the flooding slope (control at l0-20mm). Prevent water seepage from the underside of the sill door. 3. Fill the elastic material (foaming agent) in the gap between the door and window frame and the wall body, and fill it with solid material. Before the filling, the garbage in the seam must be cleaned. The coarse iron wire can be used to catch the slag, and then the skin tiger bellows can be used to blow away the dust. And check the size of the gap, more than 15mm need to make another base. Ten minutes after the foaming agent was applied, lightly press with a finger to make it compact and check for missing, voids, and incomplete images. 4. Slots shall be provided on the sides around the window frame, and the slots shall be filled with silicone for sealing. When injecting sealing materials, attention should be paid to the removal of floating mortar, etc., so that the sealing material is firmly bonded to the window frames and walls, and at the same time, it is checked whether the sealing material is continuous or missing. 5. The connector of the aluminum alloy door and window frame extends out of the frame to be anchored inside and outside. When setting, except for the one set by 180mm around the edge angle, the rest spacing should be no more than 500mm. The connecting piece shall be made of stainless steel. The thickness shall not be less than 1.5mm and the width not less than 25mm. The connection must be firmly buried. 6. Drainage holes must be opened in the downslope of the window and sliding window. The drainage holes are located at the corner of the window frame 20-140mm, and the spacing should be 600mm. After installation, check whether the drainage holes are blocked to ensure that the water in the slots can be discharged smoothly. 7. When the window cover tiles are paved, l0mm flooding should be done outwards, and the window sky plate (including the convex wall) should be used as the clear water line; the lower window plate should be made as an arc, and the bottom should be used as the panning water. Under the window plate to do the drip line waterproof. 8. Clean the smashed surface in any part of the civil construction. Wet water is needed to avoid emptying. 9. After the pulp is harvested and compacted, there should be an eagle mouth or drip line with a drip tray in the upper part of the hole. 10. Corners and surfaces are better finished at the corners at a time to prevent cracking at the junction of the first and second layers. 11. In order to make the civil construction can make a drip line, the fixed iron feet on the upper side of the pick window should be fixed on the inner side, and the outer side should not use iron feet.
