2.2 Operating conditions:
2.2.1 The quality of the structure meets the eligibility criteria after the experience is received, and the procedures for the handover of the work types are handled.
2.2.2 Stretch the centerline of the window according to the size of the picture, and play a horizontal line of 10cm, and the distance between the window and the outer wall (the so-called three-line control of the outer wall and door windows) to correct the position and size of the door and window openings meet the requirements of the design drawings. , If there is a problem, it should be dealt with in advance.
2.2.3 Check whether the position of the connecting iron legs on the two sides of the aluminum alloy door and window is consistent with the position of the reserved hole in the wall. If there is any problem, handle it in advance and clean up the debris in the reserved hole.
2.2.4 Unpacking inspection of aluminum alloy doors and windows, remove the wrapper around the window frame, check the model according to the requirements of the drawings, check the appearance quality and the flatness of the surface, if any are found, the corners, corners and warping are uneven, serious In case of defects such as excessive marks, serious injuries, and large color differences, the relevant personnel shall be found through consultation and resolution, and they shall not be installed until they have passed the qualification and qualification.
2.2.5 Carefully inspect the integrity of the protective film of aluminum alloy doors and windows. If it is damaged, it should be re-adhesive before installation.
3 Operation Process 3.1 Process Flow Erection Rules (The above three lines) → Door and window openings → Laying connection irons in doors and windows → Unpacking inspection of aluminum alloy doors and windows → Transport to installation location according to drawing number → Inspect aluminum alloy protective film → Aluminum alloy Doors and windows installation→Closing around the door window, filling insulation material→Cleaning→Installing hardware fittings→Installing door and window sealing strips→Quality inspection→Flannel fan installation.
3.2 Find the rules of the bullet line: find the edge of the door window in the upper layer, draw down the edge of the door window with a large line, and mark it at the window of each layer of the door, and cut out the individual non-straight mouth. High-rise buildings can use theodolites to find vertical lines.
The horizontal position of the door window shall be based on the +50cm horizontal line of the floor, and the opposite shall be measured upwards, and the height of the lower skin of the window shall be measured, and the line shall be straightened. The lower skin of each window (if the same height) shall be on the same horizontal line.
3.3 Mounting position in the direction of wall thickness: Determine the installation position of the aluminum alloy doors and windows in the wall thickness direction according to the large wall diagram of the exterior wall and the width of the sill plate; if the thickness of the external wall deviates, in principle, the exposed size of the sill plate in the same room should be used. Consistent with the standard, the window sill should protrude 5mm below the window of the aluminum alloy window (the distance from the outer wall to the module of the row of tiles shall prevail, and leave a 5mm groove to facilitate the sealant).

If no design is required, anti-corrosion materials such as rubber anti-corrosion coating or polypropylene resin can be used to protect the decorative film, and plastic film can also be used for protection. This will prevent direct contact of the sealing cement mortar with the surface of aluminum alloy doors and windows, resulting in electrochemical reactions. Corrosion of aluminum alloy doors and windows.
3.5.2 If the aluminum alloy doors and windows are installed with iron fittings fixed, the iron pieces shall be treated with anti-corrosion treatment. The stainless steel fittings are preferably used for the connecting pieces.
3.6 In Place and Temporary Fixation: Install according to the installed installation line, and straighten it up. After the problem is solved, use a wooden wedge to temporarily fix it.
3.7 Fixing with walls: There are three methods for fixing aluminum alloy doors and windows and walls:
3.7.1 Use electric hammer to drill φ6 hole (depth 60mm) along the outer wall of the window frame, and glue 107 cement slurry with Φφ6 steel bar (40mm×60mm), and plunge into the hole. After the cement condenses, the iron leg is finally set. Welded with embedded reinforcing bars.
3.7.2 Welded iron pieces shall be firmly welded to the embedded steel plate or the removed structural stirrups.
3.7.3 The concrete wall can use a nail gun to fix the iron foot to the wall.
No matter which method is adopted for fixing, the distance from the iron foot to the corner of the window should not be greater than 180 mm, and the distance between the iron feet should be less than 60 mm. .
3.8 Deal with the gap between the door frame and the wall: After the aluminum alloy doors and windows are fixed, the gap between the door frame and the wall should be dealt with in time. If the design does not specify the type of filler material, mineral wool or glass wool felt strips shall be used to fill the gaps, leaving 5 to 8 mm deep slots on the outer surface to fill in the caulking paste. It is strictly forbidden to use cement mortar for filling. After the anti-corrosion treatment on both sides of the door and window frame, the specified insulation material and sealing material can be filled in. After the aluminum alloy window and sill plate are installed, the gap around the window frame is filled at the same time, and the force during the filling should not be too large to prevent the window frame from being deformed after being subjected to force.

3.9.1 The reserved door hole is repaired in advance according to the size of the aluminum alloy door frame.
3.9.2 Fix the connection iron (or wooden block) on the side of the door frame.
3.9.3 After the door frame is erected according to the position, after finding the verticality and the geometrical size, the door frame and the embedded part of the wall are fixed with a shot screw or a self-tapping screw.
3.9.4 Fill the gap between the door frame and the brick wall (or concrete wall) with insulation material.
3.9.5 Fill the gap between the wall and the window frame with sealant.
3.10 Earth spring seat installation: According to the installation position of the ground spring, remove the hole in advance, place the ground spring into the well, and fix it with cement mortar. The installation quality of the ground spring must be ensured: the epithelium of the ground spring seat must be consistent with that of the indoor floor; the axis of the rotation axis of the ground spring must be consistent with the axis of the positioning pin of the door frame cross material.
3.11 Installation of aluminum alloy door leaf: The connection of the door frame fan is fixed by aluminum corner code, and the concrete method is the same as that of door frame installation.
3.12 Installation of hardware accessories: After the strength of the mortar is reached and cleaned up, the hardware fittings for the doors and windows can be installed after the inspection and inspection. The installation process requirements are detailed in the product description, and require firm installation and flexible use.
3.13 Installation of aluminum alloy screens and windows:
3.13.1 Stretched iron sand (or steel yarn, aluminum yarn), cut yarn, and batten are fixed, and the construction method is the same as that of steel wire and window.
3.13.2 hanging yarn fan.
3.13.3 equipped with hardware accessories.
