1. Advantages of high-performance aluminum alloy doors and windows Even in the country of invention of steel-plastic doors and windows and countries in Europe, steel doors and windows and aluminum alloy doors and windows are still divided equally, each accounting for about 40% of the share. High-performance aluminum alloy doors and windows with insulated cold bridges have more performance and application places that plastic steel doors and windows do not have, and that is fire performance. According to German regulations, aluminum alloy doors and windows must be used in high-rise buildings and public facilities such as hotels, schools, hospitals, shops, stations and office buildings.
High quality aluminum alloy doors and windows with insulated cold bridges are significantly superior to plastic steel doors and windows in terms of mechanical properties and physical and chemical properties. They have good sealing performance (with EPDM sealing strips), thermal insulation performance (plus insulated cold bridges and hollows) Glass), corrosion resistance (methods such as surface oxidation), weather resistance (no aging problems) and decorative (surface treatment with various colors). In addition, aluminum alloy doors and windows have better rigidity and toughness than plastic steel doors and windows.
2. The structure of aluminum alloy door and window profiles with insulated cold bridges is different from that of traditional aluminum profiles. In the sashes and window frame profiles, there are insulated cold bridges to prevent heat exchange between the interior and exterior. At the same time, consideration must be given to the sealing performance and the placement of European hardware. Its profile has its own unique structure.
3. The requirements of the European hardware on the geometrical dimensions of the aluminum alloy window profiles. Whether the window sash and the window frame profiles are manufactured separately from the inside and outside aluminum alloy profiles, the extruded bridge is used to form a cold bridge, a type of glass fiber reinforced plastic The ribbon-shaped product produced by Nylon 66 is pressed into a pre-set groove in the inner and outer aluminum alloy profiles.
a) The geometry of the sash profile is the same as the English letter “Câ€. The notches that place the hardware on the sash and connect the slide bar are usually called C slots. The internal space size of the C groove is 20<tolerance+0.3>mm×3 (tolerance+0.2, −0.1) mm, which constitutes a chute around the sash. The hardware and the slide bar push the C-slot through the special processing gaps on the four corners of the window sash. To ensure that the hardware and the slide bar can slide flexibly in the sash, the maximum dimension of the hardware and the slide bar after surface treatment is The 19.7 × 2.7mm.C groove is 15 <tolerance +0.3> mu at the opening of the groove. It cooperates with the sliding parts of the hardware and the sliding bar to play a role of positioning and guiding during the movement of the hardware.
The relative position between the sash and the window frame is positioned by two dimensions. If we set the horizontal direction to the X axis and the vertical direction to the Y axis, the sash and the window frame are 11.5 to 12 mm apart from each other in the X axis direction. This is the necessary space size for the security hardware. The extension of the inner edge of the window frame passes through the bottom edge of the C slot, and the two sides of the window drop in the Y axis direction. The size of the sash flange is 22Im ugly, and thus the sash amount between the sash and the window frame is 5.5-6mm. The hardware of the window sash is fixed to the inner surface of the snow frame profile through the upper pull rod and the upper and lower bearings, so a 3.5-5 mm hinge E-way is flashed on the yoke of the sash and window frame. When the hinge channel is 3.5mm, the weight of the hardware that withstands the sash is 9Okg. When the hinge E-track is 5mm, the thickness of the sash can be increased to 130kg because the thickness of the upper and lower shafts is increased.
b) The geometry of the window frame profile will be fitted on the window frame only. In order to make the size of the lock block uniform in two types, the size of the position of the lock block on the window frame should also be unified into two types of slots. The difference between these two kinds of slots is that the size of the openings is different, V.01 opening size is 12-14mm, suitable for thicker profiles, V.02 opening size is 9.7-11.5mIL suitable for small thickness profiles.
