[China Aluminum Industry Network] Method/Step 1. Put good quality on profiles, glass, and accessories. Secondly, in the loading and unloading of doors and windows, it is necessary to improve the degree of fineness of production. Particular attention should be paid to the sealing of the splicing between the fan and the fan and the fan and the surrounding frame when the glass is embedded. In the installation of doors and windows, pay attention to the installation of the door and window is solid, solid, filled with polyurethane foaming agent between the door and window frame and the wall, and seal the seal between the frame and the wall. It is advisable to use a glass seal at the glideslope of the window. For uniform color, seal the sealant after the glass glue is dry to prevent water leakage from the door and window.
2.Before installation, the installation position line should be popped. When installing, the verticality of the front side should be promptly checked, and the gap between the frame and the wall should be adjusted to ensure that the gap around it is even and straight up and down. The gap width should be about 10mm. Create good conditions for caulking, and it is forbidden to directly bury the door and window frame in the wall;
3, to strengthen the work of civil engineering work, the size of the hole should be reserved according to the type of internal and external decoration technology to ensure that the size of the doors and windows meet the requirements of the relevant norms;
4, to strengthen the inspection of the quality of the connection between the door frame and the wall. Strong connection is one of the key steps to ensure that the doors and windows do not seep through water. The distance from the embedded iron pieces to the corner of the door window should not exceed 180mm, and the distance between the embedded iron pieces should not exceed 500mm; the width should not be less than 25mm and the thickness should not be less than 1.5mm; The fixing method should be selected according to the type of wall: if it is a wall, it can be fixed with a 4mm or 5mm shot screw; if it is a brickwork, it can be used to drill a hole of not less than 10mm with the impact drill, and then use The plastic expansion bolts are fixed and it is strictly forbidden to use nails or cement nails for fixing; if they are small concrete blocks, they should be pre-embedded with iron pieces, and be filled with fine stone chips or be made of brick masonry near the hole;
5. When inserting boxes and walls around the seams, they should first be layered and filled with mineral wool strips, glass wool felt strips, foamed plastic strips or foamed polyurethane strips to avoid the formation of cold and heat exchange areas around the door and window frames, resulting in knots in the winter. Dew phenomenon, the appearance of the gap should be left 5-8mm deep grooves, grooves filled with sealant or sealant, cement mortar is strictly prohibited;
6. The sill slope of the lower frame of the window should be obvious. The upper part of the window should be used as the dripping line as required. The lower frame should be drilled to drain holes and prevent the sealant from being plugged to facilitate the timely removal of rainwater.
7. The rubber sealing strip used for glass inserts shall have a 20mm stretching margin and be cut off at the four angles. The disconnection must be firmly sealed with a sealant to avoid cracks caused by temperature shrinkage. The sealing strips and brush strips must be inserted. Stick it in place to prevent it from becoming a weak link in water seepage;
8. The windward surface or the rain-washing surface shall prevent the rainwater from seepage through the filling material between the door, the window and the wall, and properly consider the water stop baffle or other waterproof coating to increase the impermeability;
9. The outdoor ledge should be lower than the indoor sill plate 20mm, and set up a smooth water slope, and the rainwater can be discharged smoothly to prevent the infiltration of water. Aluminum doors and windows must have a certain distance from the outside wall to avoid direct rain erosion;
10. The material, specification and connection method of the door and window connector shall comply with the requirements of the local "Aluminum Doors and Windows Technical Specifications";
11. It is the responsibility of skilled workers to apply glue to ensure the quality of glue and avoid water leakage caused by intermittent glue.
