Window installation is a decoration project that requires a very high level of craftsmanship and care of workers. Once the installation is not in place, problems such as rain leakage and water seepage are likely to occur in the later period. And the restoration is not so easy, so it will annoy the owners. In order to avoid this kind of trouble, we should first understand the matters needing attention in window installation. Part1: Before preparing for window installation, the woodcutter must first check the window products, see if the installation environment is suitable, and if the old windows need to be removed. All such matters must be done before the window is installed. 1. Check whether the window product is qualified. The window must be inspected and accepted when entering the market. One is the appearance inspection, check whether it is damaged or broken; The second is the size acceptance, check the four sides of the frame size, check the square and warpage of the fan, so as to achieve the quality pre-control before installation. The second is to check the fasteners, hardware, reinforced profiles and metal liners, etc., to see whether the surface of the anti-corrosion treatment. If the fixing plate is used, the thickness of the fixing plate shall be greater than or equal to 1.5mm, the minimum width shall be greater than or equal to 15mm, and the surface shall be galvanized. 2, the window hole inspection want the window to have good tightness and stability, the installation of attention to flatness is the key. And to maintain flatness, the key is to deal with the window hole. Before installing the window, it is necessary to check whether the size of the hole is correct and whether it is horizontal, flat and vertical, and deal with the hole that does not meet the requirements in advance. Many owners use new windows to replace old windows, so they need to take down the old windows first. Window removal needs to be very careful to prevent damage to the window decoration and wall around the demolition. Generally speaking, wooden windows are easier to remove, while plastic steel windows and aluminum windows are more complicated. First, you need to use a blade to cut the sealant on the inside of the window, and then take the window frame. If the window is connected with the wall by expansion bolts, the expansion bolts can be removed directly with a screwdriver. If the expansion bolts are rusty, the expansion bolts can be broken with an impact drill. However, if the window frame is connected by a connecting piece, the impact drill can be used directly. If the window frame is difficult to remove, the middle of the frame against the wall needs to be sawed off with a hacksaw. Part2: Ensure that the installation specifications are well done. The installation service for windows is generally provided by the merchants. However, due to the uneven quality of services provided by the merchants and the irregular operation of some workers, the owners need to keep an eye on some key nodes to avoid negligence affecting the quality of the windows in use. 1. Size measurement When using aluminum alloy windows, the size of the balcony closed surface shall be accurately measured before the balcony is sealed, and the window frame and glass shall be processed according to the size outside the construction site and delivered to the construction site. Before installation, the size of the window should be checked to see if it is consistent with the size of the opening of the balcony. 2. Fixed bracket method 1: Before fixing the window with a fixed piece, the base layer of the balcony hole should be cleaned first. It is required to remove the base layer material of the window close to the wall, and punch holes at the fixed points. Expansion bolts or plastic expansion pins are preset to fix the window. When installing the window, the window should first sit firmly at the hole, fix its position, and fix it with screws and plastic expansion pins. Method 2: use expansion bolts to fix the general situation, the bolt needs 10cm long. If some holes are missed, they should be leveled by plastering cement, etc. The bolts need to be 12cm long so that they can be directly fixed to the cement layer of the original wall to stabilize the window frame. You can knock with your hand. If you find that the wall around the window frame is hollow, you need to hit it deeper. 3. After checking whether the window frame is connected with the window opening, check whether the window is installed correctly. If the windows are not installed correctly, the windows may become more and more crooked after a period of use. If it is a conventional rectangular window, you can directly measure the diagonal of the window (lower left corner and upper right corner, upper left corner and lower right corner), and the length of the two lines should be the same; If it is a circular window, you need to use a level ruler, and the bubble on the ruler indicates that the window is positive in the middle. If it is a tilted window, you need to use a hammer. 4. After the foaming glue window is adjusted, foaming glue is needed to fill the gap between the window frame and the wall. After the foam is cured (usually 2-3 hours, longer in winter), cut off the excess foam. 5. After installing the window sash and other accessories to fix the window frame, install the window sash and other accessories next. Pay attention to the installation carefully. 6. After the sealant is finished, the sealant is evenly applied around the window frame to prevent rainwater from penetrating into the room through the installation gap between the window and the wall.
