How to fix the billboard on the open aluminum alloy frame?
The gap between the window frame and the wall shall be treated according to the design requirements. If there is no requirement for the design, we shall use the foam material to fill in the gaps and leave a gap of 5 ~ 8mm to fill the sealing material.
After the installation of plastic steel windows, spraying tests shall be carried out in accordance with the relevant provisions so as to check their sealing performance. The installed windows must have reliable rigidity, and if necessary, additional fasteners shall be added and shall be protected against corrosion.
Specification for aluminium alloy windows installation:1, Aluminum Alloy windows are installed into the mouth should be horizontal and vertical, and the elastic frame shall be firmly connected, may not be directly buried in the wall frame.2, horizontal and vertical combinations, should be used to insert, lap, forming a surface combination, lap length of 10mm, and sealed with sealant.3, in the installation of sealing strip should be left with telescopic margin, generally than the window assembly side length of 20 to 30mm, in the corner should be inclined to open, and with adhesive firmly, so as not to produce contraction joint.
Fixing of aluminium alloy doors and windows(1) when the wall embedded pieces of iron, can be directly to the Aluminum Alloy iron doors and windows and the wall on the foot directly embedded iron weld weld to do anti rust treatment.(2) when there is no embedded iron pieces on the wall, metal expansion bolts or plastic expansion bolts can be used to fix the iron feet of the aluminum alloy doors and windows to the wall.(3) when there is no embedded iron pieces on the wall, the electric drill can also be used to hit 80mm deep and 6mm holes in the wall, and use L type 80mm * 50mm 6rmn steel bars. Glue 108 glue at one end of the hole, then into the hole. 108 glue mud after the final set, then the Aluminum Alloy doors and windows of the iron feet and buried 6mm steel welding.
