How to accept aluminum alloy doors and windows, and precautions for acceptance of doors and windows

<>1. The verticality of the window frame: it is best to measure it with a level; You can also push and pull the sash close to the window frame, leaving a slight gap, and then you can see if the upper, middle and lower gaps are the same size. If the gap between the upper, middle and lower parts is the same, it means that the window frame is vertical; Conversely, the window frame is not vertical.

2. Inspection of steel lining: put a magnet on the form you want to check, which can be adsorbed on the form, indicating that the manufacturer has added a steel lining in the profile cavity, otherwise there is no steel village. As for the thickness of the steel village, in addition to knowing it in the processing plant, you can also listen carefully to the sound of the electric hammer hitting the steel village in the window frame when the installer fixes the window frame, and feel whether it is laborious to penetrate.

3. Identification of the authenticity of the profile: look at the protective film on the surface of the profile; Second, look at whether there is an anti-counterfeiting mark (the so-called bar code) on the concave wall of the profile, call the profile manufacturer on the protective film**, and according to the prompt quotations, you can know the authenticity.

4. Whether the sash is slippery and soft when walking on the window frame track (it depends on the quality of the pulley).

5. Casement series: whether it is light to open and close; Whether it is tight after closing.

6. Whether the screen window is light to push and pull, and whether the walking is stable.

7. Glass: *** glass has no spots and no water lines (insulating glass also depends on whether the glass is clear and clean).

8. Inspection of hardware: whether the hardware brand required when signing the contract is used (whether it is light when used and whether it feels good).

9. Treatment of the gap between the window frame and the wall. According to the construction requirements, there should be at least 1 cm gap between the window frame and the wall to facilitate the filling of the construction glue (first use styrofoam to fill the gap, at least 90 minutes, the foam that runs out is leveled, and then use waterproof glue for surface treatment).

Many people do not understand the process of acceptance of aluminum alloy doors and windows and the matters that need to be paid attention to. What are the precautions for the acceptance of aluminum alloy doors and windows? PChouse let's get to know it with you.

When it comes to aluminum alloy doors and windows, we have to mention its acceptance process, and many owners don't know what matters are used to determine whether or not they are qualified when accepting aluminum alloy doors and windows.

1. Check the clearance of doors and windows, sashes and tightness, etc., which can be closed normally and closed tightly, the clearance is uniform, and the parallelism deviation between the door and window sash and the frame or the adjacent sash should not exceed 2 mm, open flexibly, use freely, and the installed aluminum alloy doors and windows should at least meet these standards in order to pass the test, otherwise they are unqualified doors and windows.

2. If there are sliding windows installed on the balcony or other places, it is necessary to see whether the upper and lower glide slides are installed smoothly, pay attention to the phenomenon of no concave and convex, and gently push the doors and windows, which should open and close and slide freely. If there is a phenomenon that it is difficult to pull up, it is necessary to check the root cause of the problem in time and solve it as soon as possible.

3. The vertical frame and transverse frame of the balcony aluminum alloy window must be firmly fixed on the balcony guardrail and the top of the balcony, and are generally fixed in the concrete with nails or rivets.

4. The surface of high-quality aluminum alloy profiles is shiny and bright, and the installation must be horizontal and vertical, consistent in height and height, and the color can not be stored in obvious color difference.

5. The wall thickness of the aluminum alloy window profile should not be less than mm, and the wall thickness of the door profile should not be less than 2 mm. The thickness of the connection between the aluminum alloy door and window frame and the wall should not be less than mm.

1. Inspection of aluminum alloy doors and windows.

The visual inspection of aluminum alloy doors and windows includes whether there are cracks on the surface, whether there is deformation and the installation inspection of the window adhesive strip, and the following is the specific operation of the inspection:

1. Visual inspection.

Look at the gloss and surface of the doors and windows to see if there is obvious uneven color. Use a ruler to measure whether the diagonal lines of doors and windows are consistent, and see if there are scratches up close.

2. Seal inspection.

The contact between the sealant and the glass and the glass notch should be smooth, and the sealing strip should not be curled or degrooved. There should be no obvious gap between the bead and the profile.

2. Inspection of aluminum alloy door and window frames.

The quality of the installation of the door and window frame directly affects the firmness of the whole door and window, and the inspection of the door and window frame can be checked from its firmness and flatness, tightness and tightness.

1. Check the vertical flatness of the frame.

Check the verticality range of the door and window frame with an infrared level, the allowable deviation of the positive and lateral verticality of the general door and window frame is, the horizontal allowable deviation of the door and window transverse frame is 2mm, the allowable deviation of the elevation of the door and window transverse frame is 5mm, and the allowable deviation of the vertical deviation of the door and window from the center is 5mm.

2. Strict density inspection of connection with the wall.

Check whether the joints between the door and window frames and the wall are tight, and whether the sealant at the joints is all laid.

These small details have a great impact on the use of doors and windows in the future, which cannot be ignored.

1. Check whether the original door opening, window opening, and window sill plate are horizontal and vertical, and whether the size of the door opening is appropriate, and if there is any deviation, it should be corrected.

2. Check whether the original door frame and window frame are square, whether there is deformation or looseness, and if so, it should be corrected.

3. The selected plate should meet the technical requirements, no shelling, no insect spots, smooth surface and refreshing texture (there is no such requirement for mixed paint).

4. Doors and window covers should be made of wood or thick plywood (nine-centimeter board, twelve-centimeter board, large core board, etc.) punched into a certain width of wood as keel, or use large core board to make the overall base, and the outer veneer should be reinforced at the hinge and door lock.

5. The connecting seams of the corners of the panel of the door and window cover and the decorative lines of the door and window cover should be at the specified angle.

6. The seams should be tight, no hammer marks, no nail holes.

7. The lines are flawless, crack-free, smooth and straight, and meet the design requirements.

8. The spacing between the fixed tenons should not be too long, and the strength is not enough if it is too thin.

The installation and acceptance of aluminum alloy doors and windows is one of the key projects in home decoration. Most owners have little experience in installation and acceptance, so it is difficult to check whether there is a problem in all directions. Next, I will explain the key points of acceptance of aluminum alloy doors and windows, let's take a look!
