[China Glass Net] Before installation, the shape and position accuracy of the door and window (door and window decoration effect diagram) should be staked out to check whether the quantity and position of the pre-embedded concrete meet the design requirements, and whether the high-rise window is connected to the lightning protection belt according to the regulations. For the unqualified part, the construction unit should be urged to rectify.
Line positioning
(1) According to the installation position, size and elevation of the doors and windows in the design drawings, the door and window edges are measured according to the center line of the door and window. In the case of multi-storey or high-rise buildings, the edge of the top and bottom windows and doors shall prevail, and the edge of the door and window shall be led by a line pendant or theodolite, and shall be marked at the door window of each layer, and the individual not straight edges shall be chiseled.
(2) The horizontal position of the doors and windows shall be measured by the horizontal line of the floor indoor +1250px, and the height of the window shall be measured downwards, and the elastic line shall be straightened. Each layer must maintain the same height of the window.
2. Aluminum window draping installation
Fix the draping on the aluminum alloy window according to the requirements of the construction drawings, and ensure that the position is correct and the installation is firm.
3. Anti-corrosion treatment
(1) When the anti-corrosion treatment design of the outer surface of the door and window frame is required, it shall be treated according to the design requirements. If the design does not require it, it can be coated with anti-corrosion coating or plastic film to protect the cement mortar from direct contact with the surface of the aluminum alloy door and window, resulting in electrochemical reaction and corrosion of aluminum alloy doors and windows.
(2) When installing aluminum alloy doors and windows, if it is fixed by connecting iron parts, it is better to use stainless steel parts for connecting iron parts, metal parts for fixing parts, etc. Otherwise, anti-corrosion treatment must be carried out to avoid electrochemical reaction and corrosion of aluminum alloy doors and windows.
4. The installation of aluminum alloy doors and windows is in place
Install the aluminum alloy door and window frame according to the planned door and window positioning line. And timely adjust the horizontal, vertical and diagonal length of the door and window frame to meet the quality standards, and then temporarily fixed with wooden wedges.
5. Fixation of aluminum alloy doors and windows
(1) When the iron parts are pre-buried on the wall, the iron feet of the aluminum alloy doors and windows can be directly welded directly to the pre-embedded iron parts on the wall, and the welding place needs to be rust-proofed.
(2) When there is no embedded iron on the wall, the iron feet of the aluminum alloy doors and windows can be fixed to the wall by metal expansion bolts or plastic expansion bolts.
(3) When there is no embedded iron on the wall, you can use the electric drill to make a hole with a depth of 80mm and a diameter of 6mm on the wall, and use L-shaped 80mm × 50mm 6rmn steel. Apply 108 cement slurry to the long end and punch into the hole. After the 108 cement slurry is finally set, the iron feet of the aluminum alloy doors and windows are welded to the embedded 6 mm steel bars.
6. Treatment between the gap between the door and window frame and the wall
(1) After the aluminum alloy doors and windows are installed and fixed, the concealed project acceptance should be carried out first. After passing the test, the gap between the door and window frame and the wall should be handled in time according to the design requirements.
(2) If the design is not required, the elastic insulation material or glass wool felt strips may be used to layer the gaps, and the outer surface is left with a 5~8mm deep notch to fill the caulking grease or sealant.
7. Door and window sash and door and window glass installation
(1) Door and window sash and door and window glass shall be installed after the decoration of the wall surface of the opening.
(2) Sliding the door and window After the door and window frame is fixed and fixed, the glass door sash is placed into the frame slide, and the gap between the frame and the fan can be adjusted.
(3) Open the doors and windows in the frame and the fan frame to assemble the wall, install and fix the glass, then adjust the gap between the frame and the fan first, then adjust the position of the glass and adjust the position. Fill in the sealant.
(4) The floor spring door should be installed and fixed after the door frame and the ground spring main body are installed in the ground. First, insert the glass into the door frame and place the frame together, adjust the gap of the frame fan, and then fill in the sealing strip and sealant of the door glass.
8. Construction precautions
(1) Pay attention to the quality of assembling when using multiple sets of aluminum alloy doors and windows. The head should be flat and not ridged.
(2) During the construction, the product protection must be strictly carried out, and the protective adhesive tape and film that have been damaged and damaged should be repaired in time to remove the dirt and stains splashed on the surface of the door and window in time to avoid contamination of the aluminum alloy door and window.
(3) The thickness of the door and window glass and the size of the fan-shaped inlay groove and the sealing strip should conform to the national standards and design requirements. When installing the sealing strip, there should be room for expansion and contraction to prevent the sealing strip from falling off.
