Do aluminum alloy doors and windows projects do glass re inspection?

It is to be re-inspected, and the following are aluminum alloy doors and windows.

Engineering quality requirements and inspection methods.

1) There is a valid product test report and quality assurance certificate issued by the supplier whose product performance meets the requirements of the national standard, and the flat glass shall comply with the "Flat Glass".

GB11614-2009), insulating glass should comply with the "insulating glass".

GB T11944-2012), laminated glass.

Should comply with the Safety Glass for Construction Part 3: Laminated Glass (GB).

Toughened glass. Should comply with the "Safety Glass for Construction Part 3: Tempered Glass" (Sunlight Control Coated Glass shall comply with "Coated Glass Part 1: Sunlight Control Coated Glass" (GB T

Low-emissivity coated glass should meet the requirements of Coated Glass Part 2: Low-Emissivity Coated Glass (GB).

2) The specifications and sizes of the glass should meet the procurement requirements.

3) The appearance quality shall be inspected according to the corresponding grade of the relevant standards, and when no specific grade requirements are proposed, the grade requirements of the qualified products shall be inspected.

1) The difference in the thickness of a single piece of glass of insulating glass should not be greater than 3mm.

2) The altitude of the place of origin and use of insulating glass.

When it is more than 800m, due to the atmospheric pressure of the two places.

The difference is about 10%, so a capillary should be installed to balance the difference between the internal and external air pressure.

5) In addition to the relevant provisions of the "Coated Glass Part 2: Low-E Coated Glass" (GB), the aluminum alloy doors and windows using low-emissivity coated glass should also meet the following requirements:

1) For low-emissivity coated glass produced by vacuum magnetic sputtering method (commonly known as off-line method), when used in synthetic insulating glass, the low-emissivity coated glass film at the contact part between the edge of the low-emissivity coated glass and the sealant should be removed, and the low-emissivity coated glass film layer should be located in the medium-air layer.

3. Inspection methods.

1) Check the quality assurance certificate and certificate.

2) Visual inspection of surface quality, its bubbles, inclusions, scratches, lines and other defects do not exceed the standard requirements.

3) Dimensions and thickness with steel tape measure, vernier caliper.

Measure, bending with steel ruler, feeler gauge. Measurement.

Testing CenterAluminum alloy doors and windowsTest Items:

1. Tightness requirements.

1. Corner sealing strip (rubber angle): The sealing strip should avoid corner splicing, and the sealing strip at the corner should be designed as a 90-degree integral rubber angle.

2. Frame fan sealing strip: Three sealing strips should be designed for the opening fan part, which are the main sealing strip, the fan edge strip and the frame edge strip.

Second, the leakage prevention requirements.

1. Drainage channels, drainage outlets, and exhaust holes (air pressure balance holes) must be set up on external windows to drain the water in the window frame sash. A buckle cover should be set on the outside of the drain to prevent strong winds from blowing rain and dust into the window sash ruler.

2. The heat insulation strip should be C-shaped structure, and the inner and outer aluminum profiles.

After compounding, on the same horizontal plane, avoid leakage and corrosion hidden dangers caused by water accumulation at the insulation strip. At the same time, the length of the thermal insulation strip can be increased to improve the thermal performance.

Type C insulating strip with the surface on the same plane as the profile.

I-type thermal insulation strip, there is a height difference between the surface and the profile, and it is easy to accumulate water.

3. The size of the door and window openings: the structural openings should not be too large to avoid the hidden danger of leakage caused by the difficulty of blocking.

4. Tongue and mouth. For special reasons, such as the exterior wall is a stone curtain wall, the reserved size of the opening is large, and the structural opening is recommended to be tongued, and the tongue and groove should be poured at the same time as the concrete wall.

5. Exterior window sill plate: For buildings where the exterior wall material is coated material, it is recommended to use metal window sill plate. The inner side of the metal window sill plate should be pressed into the window frame, and the outer side of the wall should be protruded to make dripping.

6. Window frame and structural opening: The window frame should be installed in the middle of the fiber liquid, if it is installed on the outside, it should be retracted inward 20mm to prevent the window frame from being installed outside the outer skin of the structure due to structural construction errors, resulting in rainwater leakage.

3. Frame fan structure requirements.

Group angle: Group angle is an important process related to the integrity of doors and windows.

Glue wiping process: Under normal circumstances, the corner code wiping group angle glue process should be used, and the window corner is forbidden to be extruded without plastering.

Glue injection process: The angle can also be used to inject the two-component glue corner piece process of the corner code guide groove to ensure the angle strength requirements and ensure that the finished doors and windows have no deformation and displacement after transportation and installation.

Fourth, thermal insulation requirements.

Cavity design of the profile: The profile should adopt a multi-cavity structure to reduce the loss of heat, and at the same time, the outer window insulation components should be coplanar up and down to form an overall thermal insulation surface and eliminate the cold bridge.

Block heat loss channels.

Summary. Aluminum window re-inspection generally only checks the quality and installation of the window, and usually does not need to remove the entire window.

Aluminum window re-inspection generally only checks the quality and installation of the window, and usually does not need to remove the entire window.

Can you tell us more about that?

The re-inspection of aluminum alloy windows generally refers to the re-inspection of the installed windows to ensure that the installation quality, performance and appearance quality of the windows meet the requirements. During the re-inspection, it is necessary to check whether the hardware of the aluminum alloy window is firm, whether the sealing performance is good, whether the opening and closing of the window is flexible, etc., and generally does not need to disassemble the entire window. If there is a problem in the hungry period, it needs to be repaired and adjusted in a targeted manner.

Only by re-inspecting and ensuring the safety, reliability and performance of the windows meet the requirements can we ensure the safety of life and property, anti-theft effects, etc., and prolong the service life of the windows.
