For example, how to check the installation quality of plastic steel doors and windows. a) Look at the window surface: the window frame should be clean, smooth, smooth, no scratches or bumps on the large surface, and the profile is not broken. 2) Look at the hardware: the hardware must be complete, the position is correct, the installation is firm, the use is flexible, and the respective functions can be achieved. 3) Look at the glass sealing strip: the contact between the sealing strip and the glass and glass notch should be flat, and it should not be curled or undulated. 4) Look at the quality of the seal: When the door and window are half-closed, there is no obvious gap between the fan and the frame, and the seal on the sealing surface should be in a compressed state. 5) Look at the glass: the glass should be flat and firm, and there should be no looseness. The single-layer glass should not be in direct contact with the profile. The inner and outer surfaces of the double-layer glass should be clean. There should be no dust or moisture in the glass interlayer. The spacers cannot be lifted. . 6) Look at the bead: The bead with the sealing strip must be tightly attached to the glass. There should be no obvious gap between the bead and the joint of the profile. The joint gap should be less than or equal to 1 mm. Push-pull. VII) Look at the smashing material: The splicing material should be tightly connected with the window frame, and sealed with the caulking paste. It should not be disturbed. The screw spacing should be less than or equal to 600 mm. Both ends of the lining reinforced steel should be firmly fixed to the hole. VIII) Look at the switch components: Swing, push-pull or rotating windows should be closed tightly. IX) The connection between the frame and the wall: the window frame should be horizontal and vertical, the height should be consistent, the spacing of the fixing piece should be less than or equal to 600 mm, the frame and the wall should be firmly connected, the gap should be filled with elastic material, and the surface seal can be sealed. , no cracks. X) Look at the drainage hole: the drainage hole should be in the correct position and at the same time be smooth.
