the service life of doors and windows is generally relatively long, but if the installation process of aluminum alloy doors and windows and the installation inspection of aluminum alloy doors and windows are not careful, a little deviation will affect the overall use effect. Today, I will talk to you about the installation process of standard size aluminum alloy doors and windows, the installation inspection of aluminum alloy doors and windows and the method of aluminum alloy door and window maintenance.
I. Installation process of aluminum alloy doors and windows
① check the building base: check the size of the opening and check whether the load-bearing building base is hung with a separated surface structure to prevent the fixed part from splitting with the main body after bearing.
② cut the attached frame according to the specification, and Tenon the profile to extend it to meet the installation requirements.
③ apply special strong sealant on aluminum alloy door and window profile as required, and fix the profile around the building hole according to the design size.
④ confirm the position of the attached frame for horizontal calibration and use special connecting screws to fix it. The other three sides are the same as above.
⑤ paste special pre-pressure expansion sealing tape around the window frame and install it to the window.
⑥ calibrate the window frame and use special screws to connect the attached frame and window frame from the room after it is correct.
⑦ paste airtight film at the installation gap between aluminum alloy doors and windows and attached frames (increase air tightness guarantee).
After the installation process of aluminum alloy doors and windows is completed, four aspects of doors and windows should be inspected, including appearance, profile, hardware, opening and closing. The following are some installation and inspection methods of aluminum alloy doors and windows found by the editor.
II. Installation Inspection of aluminum alloy doors and windows
aluminum alloy doors and windows installation inspection: door leaf, Casement
the surface quality of aluminum alloy doors and windows directly affects the decorative effect of the whole wall after installation. The appearance inspection of aluminum alloy doors and windows includes whether there are cracks on the surface, deformation and installation inspection of window adhesive strips. The following are the specific operations of the inspection:
1. Seal inspection
the contact between sealant and glass and glazing rebate should be smooth, and the sealing strip should not be rolled or slotted. There should be no obvious gap at the joint of layering and profile, and the joint gap should be less than 1mm.
2. Appearance inspection
see whether the gloss and surface of doors and windows are obviously uneven in color. Then use a ruler to measure whether the diagonal lines of doors and windows are consistent, and look closely to see if there are scratches.
Aluminum alloy doors and windows installation inspection: Frame
the installation quality of door and window frame directly affects the firmness of the whole door and window. The inspection of door and window frame can be checked from its tightness, firmness and smoothness.
Check the strict density of the connection with the wall. Check whether the joints between the frame of doors and windows and the wall are tight, and whether the sealant at the joints is well laid.
Border vertical flatness check. Check the verticality range of the door and window frame with an infrared level meter. Generally, the allowable deviation of the verticality of the front and side of the door and window frame is 2.5mm, and the allowable horizontal deviation of the horizontal frame of the door and window is 2mm, the allowable deviation of horizontal frame height of doors and windows is 5mm, and the allowable deviation of vertical deviation from center of doors and windows is 5mm.
Aluminum alloy doors and windows installation inspection: window lock
door and window hardware is related to the safety of doors and windows. When checking lock, attention should be paid to whether the installation is firm and whether the key rotates freely.
1. Lock use check to see whether the door lock is flexible and whether the anti-lock and unlocking actions can be carried out smoothly; Then check the window, close the window lock, and push the mobile window by hand, check whether the window is locked or not.
2. Lock installation check the inspection of lock devices. First, check whether the installation position of lock is correct and whether it is installed in reverse mode. Check whether the installation on both sides of the lock corresponds and whether there is any dislocation. Then shake lock with your hands to see if there is any loose phenomenon.
Installation Inspection of aluminum alloy doors and windows: use inspection
the last step: check the opening and use of doors and windows, including whether the opening and closing of doors and windows are stable and whether there is abnormal shaking after the doors and windows are locked.
Finally
shake back and forth with your hands doors and windows, check whether the use of doors and windows is normal, and feel whether the doors and windows are subject to abnormal resistance and sound during shaking; Then change the strength of the window and check whether the doors and windows can withstand different forces. Close the doors and windows to check whether the doors and windows are sealed with the border. Sliding door should check push and pull.
After the installation process of aluminum alloy doors and windows is completed, we also made a very detailed inspection on the installation inspection of aluminum alloy doors and windows, but there may be some problems in the installation process of aluminum alloy doors and windows, or the installation inspection of aluminum alloy doors and windows is not done carefully, which leads to shaking, leakage or obvious color difference of aluminum alloy doors and windows. At this time, we need to know the causes of these problems in aluminum alloy doors and windows and how to door and window maintenance aluminum alloy.
III. Aluminum alloy door and window maintenance method
1. Leakage of aluminum alloy doors and windows
phenomenon:
(1) leakage at the junction of the door and window frame and the surrounding wall.
(2) accumulate water within sliding window under sliding chute and penetrate into the window.
Reason:
1. Door and window frames and for walls cement mortar caulking.
2. The glue injection between the door and window frame and the wall is not strict and there is a gap.
3. The craft of doors and windows is unqualified, and the combination between window frame and Casement is not strict.
4. The installation of Casement sealing strip is unqualified, and water seeps into the Casement glass seam.
5. The window frame has no drainage hole.
Aluminum Alloy door and window maintenance method:
1. Doors and window frames and walls shall not be caulked with cement mortar. It should be connected elastically and sealed with sealant, without gaps.
2. Before installation, check whether aluminum alloy doors and windows are qualified, whether the combination between window frame and Casement is strict, and whether the installation of Casement sealing strip is qualified.
3. There is a gap of more than 50mm between the window frame and the hole, so that the window sill can make a running slope.
4. Drain holes should be drilled for the lower frame and track root of the outer frame.
2. Aluminum alloy door and window frame overall stiffness difference
phenomenon:
push and pull or open and close doors and windows or in windy weather, the door and window frames shake.
Reason:
1. Improper selection of profiles, small section, insufficient rigidity. The prevention of aluminum alloy door and window materials does not meet the requirements. The quality of plastic steel door and window materials is unqualified.
2. The steel lining configuration of plastic steel doors and windows does not meet the standard. (generally, 1.20 is used for steel lining, but the owner cannot see it because it is installed. Many merchants use unqualified ones to install them to the owners) the strength of steel wall hail is poor; The lining steel is inserted in sections, and the shape cannot be strengthened as a whole; The lining steel is not firmly connected with plastic profiles, etc.
3. The installation node is not in accordance with the specifications.
4. Different fixing methods are not adopted according to different walls.
Aluminum Alloy door and window maintenance method:
1. The specifications and quantity of door and window frame profiles meet the national standards. The outer frame wall thickness of aluminum alloy profiles shall not be less than 2.4mm. The thickness of plastic steel window material shall not be less than 2.5mm.
2. Check the appearance of plastic profiles. Qualified profiles should be bluish-white or ivory white, clean and smooth. Good quality should have protective film.
3. Select the profile section according to the opening size and installation height of doors and windows. The casement window is not less than 55 series and the sliding window is not less than 75 series.
4. Install in strict accordance with the specifications to ensure firm and stable.
3. Aluminum alloy doors and windows have obvious color difference
phenomenon: the adjacent doors and windows or window frames are inconsistent with the color of the fan.
Reason: The material is not the same factory product, or the same batch of products, or products of different material grades.
Aluminum Alloy door and window maintenance method:
1. When purchasing profiles, the same manufacturer's products should be used and sufficient materials should be prepared at a time.
