Plastic steel doors and windows product quality inspection standards The product quality inspection requirements for the group fan workshop are as follows: Check that the glass size in the drawing is correct, and check the glass without error. After cutting the plan, it is guaranteed to lose within 5% of the cut glass. When making hollow glass, the desiccant must reach the length of the aluminum tube by 95%. The hollow glue should be light and seamless, not breathable, no impurities in the middle of the glass and no scratches on the glass. The aluminum strip in the middle of the fan glass and the middle aluminum strip of the bright glass are glued straight, the interface is tight, and the hollow glue is applied to the interface. When grouping the fan, put the glass block around the fan first, add more than 3 anti-vibration blocks, add more than 2 anti-vibration blocks, put the cut glass into the glass, and finally fix the glass with glass bead. To select the strip, the strip must be flattened and straightened without gaps. After the group fan is completed, the quality inspector will take a sample inspection and affix the certificate to leave the factory. Unspecified implementation according to the construction industry standards of the People's Republic of China. The above provisions are the responsibility of the parties if there is a violation. The quality inspection requirements for the blanking workshop are as follows: Inspect the frame, fan, sliver, cover, and the size of the strip in the drawing. The number of the strip is correct. Check the material without error and then press the plan. The size error of the blanking shall not exceed 0.5mm; the number of solid parts for fixing each reinforced steel shall not be less than 3, the spacing shall not be more than 300mm, the distance from the steel end shall not exceed 100mm, the reinforced steel after fixing shall not be loose, and the reinforced steel The surface must be rust-proofed. The diameter of the milling drain hole is 5mm and the length is 20mm. The drain hole should be placed in the cavity with the reinforced steel, and the chamber with the reinforced steel should not be pierced. 80 double bead, 60 double bead cut angle must be 45 °. The frame is lower than 1200mm, and the fan is less than 700mm without increasing the profile steel, which is carried out as required. The position of the fixture should be positioned according to the drawings. Unspecified implementation according to the construction industry standards of the People's Republic of China. The quality inspection requirements for the installation team are as follows: Check the size of the plastic window opening, and then move the plastic windows of different specifications to the corresponding hole. When the window frame is installed in the hole, the upper and lower frame lines should be aligned with the center line of the hole; the symmetrical position of the four corners of the upper and lower frames of the window and the middle horizontal frame should be temporarily fixed by the small wedge or the block, and the wooden wedge should be parallel to the frame. Then fix it to the wall with nails or expansion screws. Adjust the verticality, levelness and straight angle of windows, frames and fans. The glass is not allowed to be in direct contact with the glass trough. The anti-vibration blocks of different thicknesses should be placed on the four sides of the glass, and then the glass is fixedly clamped by the glass bead. The hardware accessories are in the correct position, complete in quantity, safe and secure. Unspecified implementation according to the construction industry standards of the People's Republic of China. The above provisions are the responsibility of the parties if there is a violation. The quality inspection requirements for the welding shop are as follows: The inspection frame and fan size are consistent with the size of the drawing. The frame and fan should be vertical. If the frame or fan is to be worn, the steel lining should not be welded if it does not meet the above requirements. According to the drawings, the frame, the fan and its diagonal dimensions after welding, wherein the error is not more than 3mm, the welding must be consistent with the size of the drawing. The finished product is marked with the specifications and model. If there is any error, it is not allowed to enter the warehouse. Otherwise, The problem is caused by the welding shop. The tops are not allowed to be too long or too short. It is necessary to wear the tops according to the length of the fan, and the pulleys and the pads should be fastened. The clear angle must achieve the effect of a groove and a rule. Group frame, 3 screws should be guaranteed for the frame below 1500mm, and 4 screws for the frame with the middle of the frame. The pressure of 60 double bead is standard. The 60 pairs of bead are short or long and must not be replaced. After the welding, the quality inspector will be sampled. Unspecified implementation according to the construction industry standards of the People's Republic of China.
