1. Bullet line positioning
Use large Line Pendant along the full height of the building (high-rise buildings should use theodolite to find a perpendicular line) to test doors and windows, and mark the window of each door. And copy and test the actual distance between the door and window opening and the door and window edge line layer by layer, and record and mark those that need to be processed.
The horizontal position of doors and windows should be based on the horizontal line of 0.5m inside the floor to measure the height of leather tag below the window in reverse direction, and the elastic line should be straight. Each floor must keep the height of leather tag under the window consistent, and the lower opening of aluminium alloy door should be 0.51m.
The installation position of the wall thickness direction should be determined according to the design requirements and the official crossing of sill plate. In principle, the exposed size of sill plate in the same room shall be the same, and sill plate shall be extended to 5mm below aluminium windows.
2. Door and window opening treatment
If the opening of doors and windows is offset, not vertical or square, chisel or plastering shall be carried out.
3. Anti-corrosion treatment
When the four outer surfaces of the door and window frame have anti-corrosion treatment design requirements, they shall be treated according to the design requirements. If there is no requirement in the design, anticorrosive paint can be painted or plastic film can be pasted for protection, so as to avoid cement mortar directly contacting the surface of aluminum alloy doors and windows, causing chemical reaction and corrosion of aluminum alloy doors and windows.
When installing aluminum alloy doors and windows, if connecting iron parts are used for fixing, it is better to use SST part for connecting iron parts, fixing parts and other installation metal parts. Otherwise, anti-corrosion treatment must be carried out to avoid electrochemical reaction and corrosion of aluminum alloy doors and windows.
4. Aluminium windows water-covering installation
According to the actual requirements, it should be fixed on the aluminum alloy bed by covering water, and the position should be correct and the installation should be firm.
5. Installation of aluminum alloy doors and windows in place
Install aluminum alloy door and window frame according to the painted positioning line of doors and windows, and then temporarily fix it with wooden wedge.
6. Fixing of aluminum alloy door and window frame
Aluminum Alloy door and window frame the fixing of the wall is generally connected with fixing pieces, and the fixing pieces are mostly galvanized plates with a thickness of 1.5mm, and the length is processed according to the needs of the site.
The connection between Road alloy door and window frame and wall opening should be firm and reliable, and the distance between fixed points should not be more than 600mm, and the distance from howling should not be more than 180mm.
There are three main methods for fixing iron feet and walls:
1. When there are iron pieces on the wall, the fixing pieces of aluminum alloy doors and windows can be directly welded with the embedded iron pieces on the wall, and the welding place needs rust prevention treatment.
2. When there are no embedded iron parts on the wall, metal expansion bolts or plastic expansion bolts can be used to fix the fixing pieces of aluminum alloy doors and windows on the high wall.
3. When there are no embedded iron parts on the wall, electric drills can also be used to punch holes 8mm deep and 6mm in diameter on the wall with L-shaped 80 × 50mm 6mm steel bars. Stick 108 glue mud in a long section, and then drive it into the hole. After 108 glue mud is finally solidified, the iron feet of aluminum alloy doors and windows and the embedded 6mm steel bar shall be welded firmly.
7. Handling of clearance between door and window span and wall
After the installation and fixing of aluminum alloy doors and windows, the concealed engineering acceptance should be carried out first, and the gap between the door and window frame and the wall should be handled timely according to the design requirements after passing the acceptance. If the design is not required, Styrofoam fill plug gap can be used, elastic insulation materials or glass wool felt strips can also be used to layer fill plug, and 5mm-8mm deep notches on the outer surface can be filled with caulking grease or sealant.
If the side of the door and window frame has been anti-corrosion treatment, it can also be filled with low alkaline fine stone concrete. Aluminium windows the upper seam and the lower seam should be embedded at the same time sill plate after installation. When filling, do not force too much to prevent the window frame from being deformed.
8. Aluminum alloy door frame installation
Aluminium alloy door the fixing method of the upper frame and the side frame, as described in paragraph 6, the fixing method of the lower frame varies according to the situation type of aluminium alloy door.
(1) vertical hinged door can adopt embedded parts see six two, expansion bolt connection, fastener connection or embedded steel plate welding method.
(2) sliding door lower frame can be directly embedded into the ground concrete.
(3) because the floor spring door has no lower frame, the frame is directly fixed in the ground, and the floor spring is also buried in the ground and fixed with cement slurry.
9. Doors and windows fan and doors and windows fan glass should be installed after the completion and acceptance of the opening wall surface finishing.
Push-Pull doors and windows after the installation and fixing of the door and window frame, put the doors and windows with glass into the frame sliding chute. Just adjust the gap with the fan.
Vertical hinged door the window frame and the fan grillwork are assembled on the wall, and the installation is fixed before Anbo flow. That is to say, first adjust the gap between the frame and the fan, put the glass into the fan and adjust the position, and finally inlay the sealing strip and sealant.
Floor spring the entry should be fixed after the door frame and floor spring main engine are installed. Now embed the glass into the grillwork of the fan and put it into the frame, adjust the gap of the frame, and finally fill the sealing strip and sealant of the door leaf glass.
10. Installation of hardware accessories
Galvanized screws are used for connecting hardware fittings with doors and windows. The installed hardware accessories should be firm and flexible to use.
