[China Glass Net] Aluminum alloy door and window installation specification
If there is a block phenomenon when opening and closing the door and window, the switch needs a lot of strength, the width of the frame fan is small, and the unevenness of the surrounding gap is generally caused by the following factors:
(1) The door and window frame or the fan is deformed, and the sealing strip is loosened.
(2) Hardware accessories are damaged.
(3) The installation quality is poor, and there are many deviations from the allowable deviation, and it has not been adjusted in time.
Prevention:
(1) Door and window installation should comply with the installation process, and check and adjust the installation quality of each process at any time.
(2) The window frame and the window hole should be drawn out of the middle line. When the window frame is installed in the hole, the center line should be aligned, the frame angle should be temporarily fixed, and the verticality, horizontality and straight angle of the window frame should be carefully adjusted. The error should be within the allowable deviation range. .
(3) Check the diagonal and flatness deviation before the door and window fan enters the frame. After the frame, check the overlap width of the frame fan and the surrounding gap with the steel ruler and the feeler gauge until the requirements are met.
(4) Correctly install the hardware parts and find that the damage should be replaced in time.
(5) Do a good job of product protection and normal use and maintenance, to prevent external impact, and not to hang heavy objects, resulting in deformation of doors and windows. When using, it should be lightly closed to extend its service life.
The aluminum alloy door and window frame is cracked at the joint of the wall; when the door and window are pushed or pulled, the frame fan is shaken; when the wind is pressed or pulled by hand, the window frame is deformed greatly and shakes, giving people an insecure feeling.
The reasons for these quality problems are:
(1) The door and window profiles are not properly selected, the specifications are small, and the profile thickness is thin.
(2) The connection and fixing method of the door and window frame with the wall is improper.
(3) The structure of the combined door and window splicing is unreasonable, the connection is not strong, and deformation occurs after being stressed.
To solve these problems, the following prevention measures should be taken:
(1) Aluminum alloy doors and windows should be selected according to the size of the door and window opening and the installation height. The section of the aluminum alloy profile used for residential engineering is not less than 55 series in the form of casement window; not less than 75 series of sliding window; not less than 75 series of casement window of inner balcony. The wall thickness of the aluminum alloy window profile is not less than 1.4 mm, and the wall thickness of the door profile is not less than 2 mm.
(2) When the door and window frame is installed, the connecting piece should be connected with the wall for reliable connection. The distance between the connecting members and the corners of the frame shall not exceed 180 mm, and the spacing between the connecting members shall not exceed 50 mm. The connecting piece shall be made of thin steel plate with a thickness of not less than 1.5 mm and shall be treated with anti-corrosion treatment. The connection method generally uses an expansion bolt, a needle, or an iron foot to be buried in the wall. The door and window frame must not be directly nailed to the wall by a circle or a needle.
(3) When installing the combined doors and windows, it is necessary to pay attention to the reasonable setting of the middle and middle gears to ensure the overall rigidity of the splicing bars and doors and windows. The specification spacing of the connecting parts meets the requirements and should be tightly connected.
In daily use, it is sometimes found that leakage occurs in the vicinity of the aluminum alloy door and window frame and the wall, especially in the lower corner of the window; secondly, water seepage occurs at the joint of the combined window.
There are two main reasons for water seepage:
(1) Cracks are formed at the joint between the door and window frame and the wall, and the seal is not filled with sealant during installation, and rainwater seeps into the room from the crack.
(2) When the combination of door and window splicing, no socket or lap joint is adopted, and no sealant seal is used.
In order to prevent water seepage of the door and window frame, corresponding measures should be taken during construction:
(1) Because the thermal expansion coefficient of aluminum alloy profiles and wall materials is different, under the influence of temperature, capillary cracks are easily generated at the joint between the frame and the wall. In order to prevent water seepage at the cracks, the aluminum alloy door and window frame should be elastically connected with the wall. The outside of the frame should be embedded with wooden strips, and a 5mm×8mm notch should be left to prevent the cement mortar from directly contacting the frame. During construction, the floating ash, mortar granules and other debris in the joint groove should be removed first, and then the sealant is sealed around the inside and outside of the frame and the wall is sealed. The glue should be continuous, do not miss, and the bond should be firm. .
(2) When splicing the door and window members, the socket or lap joint should be used, the lap length is not less than 10mm, and then sealed with sealant. It is strictly forbidden to adopt the combination of plane and plane. At the same time, the exposed connecting screws should also be sealed with a sealant to prevent water seepage.
China's 2010 development plan puts forward new standards for building energy conservation and requires the implementation of 50% of building energy efficiency. In the buildings, doors, windows, walls, roofs and floors are the four major parts of building energy consumption, and the doors and windows are ranked first, accounting for about 50%. Therefore, the development of new structure doors and windows is first adapted to the requirements of building energy conservation. Broken bridge aluminum doors and windows basically meet the needs of construction in progress, heat preservation, heat insulation, sound insulation performance, and anti-condensation, energy saving of about 50%, is a green product.
I. Wind pressure resistance and structural deformation performance of aluminum doors and windows
The reason why the aluminum alloy doors and windows of broken bridges are widely promoted is mainly due to its own easy processing and high strength performance. This broken bridge product will not affect its performance due to the use of new technology, and still retains the easy processing and resistance to wind pressure and deformation of the aluminum alloy itself, so that it does not require special maintenance. At the same time, in order to meet the requirements of various levels of buildings, various processes such as fluorocarbon spraying, electrostatic spraying and anodizing treatment provide colorful colors and strong decorative effects.
2. Insulation and sound insulation performance of aluminum alloy doors and windows for broken bridge insulation
Broken bridge insulation aluminum alloy doors and windows are filled with PU resin in the special design aluminum alloy cavity, and then the aluminum wall is separated to form a broken bridge. Prevents the conduction of heat. And with 5+12A+5 hollow glass, the thermal conductivity K value is reduced from 5.93W/m2K of ordinary aluminum doors and windows to 2.94W/m2K. The winter room heating and summer air conditioning refrigeration energy saving more than 40%. In the cold winter temperature difference of 500C, the door and window will not cause condensation, thus solving the problem of ordinary aluminum alloy doors and windows on indoor decoration pollution. At the same time, the sound insulation performance of the doors and windows is maintained at 30-40dB, which enables people to have a quiet and warm space in the downtown area. EAH insulation doors and windows aluminum alloy doors and windows series products use the principle of combining equal pressure and four-way sealing, making the airtightness reach the national standard and the watertightness reaches the national standard.
3. Application of broken bridge insulation aluminum doors and windows
Once the EAH insulation aluminum alloy doors and windows were introduced, they were favored by the majority of users with their excellent performance, and achieved good economic and social benefits.
According to user feedback information: EAH series insulation aluminum alloy doors and windows is a true energy-saving and environmentally friendly product. The reason why EAH series insulation aluminum alloy doors and windows have received attention and support from all walks of life is because the products themselves have enormous social benefits. Through theoretical calculations, the energy saving of aluminum alloy doors and windows of EAH insulation is about 50%, and an ordinary room can save 4.5 tons of coal and 460 degrees of electricity per year. The heating and cooling costs saved during the use process can make up for the high part of the initial installation fee in a short period of time, which can be said to be a lifetime investment benefit.
The use of EAH insulation doors and windows has no worries about aging and no gas pollution. After the building has reached the end of its life cycle, doors and windows can be recycled without environmental pollution for the next generation. Therefore, when the product is selected, we resolutely identify it as a “green†product.
