1, the edge of the plastic-steel sliding door should be pried off first, and the edge is at the intersection of the two doors. First remove the crescent lock with screws, then pry it from one end of the sealing edge with flat head screws or shovels and put it on the slide way! Follow the reverse steps to install.
2. The metal slideway of plastic-steel window is a strip-shaped material rolled by thin metal plate. The cross-sectional shape of the strip profile of the metal slideway of the plastic steel window is a rectangular square groove. The cross-sectional shape of the strip profile of the metal slideway of the plastic steel window is the shape and size of a rectangular square groove, which is the same as the cross-sectional shape of one side of the plastic outer frame profile in the prior art. ..
3. The cross-sectional shape of the strip profile of the metal slideway of the plastic steel window is rectangular, and the square groove can be tightly sleeved on the convex edge with rectangular cross-sectional shape on one side of the plastic outer frame profile.
4. The utility model can be tightly sleeved on the convex edge with rectangular cross section at one side of the plastic frame profile, and the plastic frame profile covered with the utility model can be made into the lower frame of the plastic steel window frame. When in use, the metal under the sash of the plastic steel window is thin stainless steel.
Extended data
Generally speaking, the air leakage of plastic steel windows is caused by several factors:
1, air leakage between window frames and walls comes from air leakage between window frames and walls. Generally, there is floating ash at the junction of indoor side window frames and walls. The more obvious, the more serious. This needs to be sealed with glue. If the gap is large, it needs to be filled with styrofoam first, and then treated with sealant. It is suggested to choose "neutral silicone sealants" or "neutral silicone weather-resistant adhesive".
2. If the hardware is not installed correctly, or it is not locked for some reason after a period of time, it is necessary to adjust the hardware to achieve a good locking effect. If it is serious, some hardware accessories may need to be replaced.
3. The air leakage caused by the deformation of the window sash will be deflected due to the plastic material. The longer a single bar is, the greater the deformation may be. Therefore, in our maintenance, there are many air leaks caused by window sash deformation. For the deformed window sash, if it is not serious, it can be corrected by installing an intermediate lock;
If the deformation is serious enough, it may be necessary to replace the sash. By the way, in our annual winter maintenance, we will encounter the practice of adding a roof or sealing strip to the window sash and window frame, which is very undesirable. Harnessing the air leakage of window sash is just like harnessing flood. It should be "drained" but not "blocked". Using rubber strip or wool tops to "block" can only make the window sash more deformed.
4. Air leakage caused by the corner of the window sash Due to the heavy weight of the insulating glass of the window sash, if the gasket is not properly padded during installation, the window sash will fall off. For small corner loss, it can be reset by adjusting the hardware. If the corner falls badly, the glass should be removed and re-padded.
5. Air leakage at the corner of the batten connection During maintenance, many customers will report air leakage at the corner of the batten. In fact, in plastic windows, each window frame has a drainage system, and the drainage holes on the outside are connected with the cavity where the insulating glass is placed. Cold air will enter the glass cavity along the drainage hole. If the diagonal of the batten is lax or the rubber strip is missing, air leakage will be felt. Seal the diagonal of the batten with sealant.
6. The aging or missing rubber strip leads to air leakage, so it is necessary to replace the aging rubber strip or the missing rubber strip to achieve the sealing effect.
