[ä¸çŽ»ç’ƒç½‘] 1. The door leaf switch is not smooth The main reason is that the lock is installed. The tongue plate should be removed and the tongue groove should be repaired with a chisel. Adjust the position of the door lock tongue and then install the lock tongue. 2. Door and window sash and frame gap are large The main reason is that the installation is not correct and the door and window frame is not perpendicular to the ground. The door and window sash can be removed and repaired until it is in line with the frame. If the door and window frames are not vertical, the gasket should be straightened in the frame. The surface of the door cover is knocked with a drum sound by hand, indicating that the bottom layer is not lined with the large core board, and the large core board should be added after the panel is removed. 3. Sliding the door and window when sliding The main reason is that the centerlines of the upper and lower rails or rail grooves are not in the same vertical plane. The centerline of the upper and lower rails or rail slots should be aligned vertically by adjusting the track position. 4. The side of the window opening is not vertical The main reason is that there is no straightening of the wood chips, and the mat should be reworked. After measuring with a long rule, the cushions are installed. 5. The surface has chromatic aberration, damage, rot, crack, etc. All must be replaced with a veneer. The use of wood for the door and window cover should not be large with the wood of the door and window sash, the color matching veneer and the wood line. 6. Hardware installation quality is poor The reason is that the hinge of the swing door is not causing the door and window sash and the frame to be uneven. You can unscrew one screw from each hinge and adjust the flatness of the door and window and the frame. Then correct all the screws and then tighten all the screws. If the hinge screw is short, the screw is screwed in and tilted at a time, the appropriate screw should be replaced when the door and window fan is repaired. The upper screw must be screwed into the full length of 1/3 and then screwed into the remaining 2/3. Do not nail or tilt it once.
