  • Detail

The surface of aluminum alloy is bright and shiny through oxidation. The window sash has a large structure, which can be inlaid with a large area of glass, so that the indoor light is bright enough, which enhances the contrast between the facade outside and inside the room, and makes the room more layered. Aluminum alloy itself is easy to knead, the cross-sectional dimension of profile is accurate, and the processing accuracy is high. Therefore, many owners choose aluminum alloy doors and windows in decoration. Next, we will introduce the standard process of aluminum alloy doors and windows and devices

device process: marking and positioning → aluminum alloy door and window flashing device → anti-corrosion treatment → aluminum alloy door and window device in place → aluminum alloy window fixation → treatment of the gap between door and window frame and wall → door and window leaf and door and window glass device → device hardware accessories

1. Marking and positioning

(1) measure the side lines of doors and windows from the center line of doors and windows to both ends according to the device orientation, scale and elevation of doors and windows in the planning drawings. If it is a multi-storey or high-rise building, the side line of the door and window on the top floor shall prevail, and the side line of the door and window shall be led down with a plumb or theodolite, and a symbol shall be drawn at the door and window on each floor. A single non straight edge shall be chiseled

(2) the horizontal orientation of doors and windows should be based on the horizontal line of +50cm in the floor, measure the elevation of the lower skin of the window upward, and snap the line for alignment. It is necessary to adhere to the same elevation of the lower surface of the window on each floor

2, aluminum alloy door and window flashing device

fix the flashing on the aluminum alloy window according to the requirements of the construction drawing, and ensure accurate orientation and robust device

3. Anti corrosion treatment

(1) when there is a request for the anti-corrosion treatment plan of the external surface near the door and window frame, it shall be handled according to the planning request. If there is no request in the plan, it can be painted with anti-corrosion paint or pasted with plastic film for maintenance, so as to avoid cement mortar directly touching the surface of aluminum alloy doors and windows, causing electrochemical reaction and corrosion of aluminum alloy doors and windows

(2) when installing aluminum alloy doors and windows, if connecting iron parts are selected for fixation, stainless steel parts are best used for connecting iron parts, fixed parts and other metal parts for devices. Otherwise, it is necessary to carry out anti-corrosion treatment to avoid electrochemical reaction and corrosion of aluminum alloy doors and windows

4. Put the device of aluminum alloy doors and windows in place

install aluminum alloy door and window frames according to the marked door and window positioning line. And timely adjust the level, straightness and diagonal length of door and window frames to meet the quality standards, and then temporarily fix them with wooden wedges

5. Fixation of aluminum alloy doors and windows

(1) when iron parts are embedded on the wall, the iron feet of aluminum alloy doors and windows can be directly welded with the embedded iron parts on the wall, and the welding joint 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 iron feet of aluminum alloy doors and windows to the wall

(3) when there are no embedded iron parts on the wall, electric drills can also be used to drill holes 80mm deep and 6mm in diameter on the wall, using L-type 80mm × 50mm 6rmn reinforcement. Apply 108 glue slurry to the long end, and then drive it into the hole. After the final setting of 108 glue slurry, weld the iron feet of aluminum alloy doors and windows with the embedded 6mm reinforcement

6. Treatment of the gap between the door and window frame and the wall

(1) after the aluminum alloy door and window device is fixed, the concealed works should be inspected first, and the gap between the door and window frame and the wall should be treated in time according to the planning requirements after passing the inspection

(2) if the planning is not requested, elastic insulation materials or glass wool felt strips can be used to fill the gap layer by layer, and a 5~8mm deep notch is left on the outer surface to fill with caulking paste or sealant

7. Installation of door and window leaves and door and window glasses

(1) door and window leaves and door and window glasses shall be installed after the completion inspection of the exterior decoration of the hole wall

(2) after the sliding door and window are fixed in the door and window frame device, install all the door and window leaves equipped with glass into the chute in the frame, and adjust the gap with the leaf

(3) for casement doors and windows, install the glass after the frame and fan grid are assembled on the wall and the device is fixed, that is, first adjust the gap between the frame and the fan, then install the glass into the fan and adjust the orientation, and finally inlay the sealing strip and sealant

(4) the floor spring door should be installed after the door frame and the floor spring main machine grounding device are fixed. First, insert the glass into the door leaf grid and put it into the frame in place together, adjust the gap between the frame and leaf, and finally fill in the sealing strip and sealant of the door leaf glass

the installation standards of aluminum alloy doors and windows are roughly these. Even if you ask a decorator, you can check whether the project is qualified according to this standard

8. Hardware fittings of the device

galvanized screws for the connection between hardware fittings and doors and windows. The hardware fittings of the device should be robust and sensitive to use

9. Construction precautions

(1) pay attention to the assembly quality when selecting multiple groups of composite aluminum alloy doors and windows, and the splicing head should be flat without splitting edges and channeling angles

(2) during construction, it is necessary to strictly maintain the products, timely seal the damaged and falling maintenance tapes and films, and timely remove the mortar dirt splashed on the surface of doors and windows to avoid the pollution and biting of aluminum alloy doors and windows

(3) the cooperation between the thickness of door and window glass and the dimension of stile inlay groove and sealing strip should conform to the national standards and planning requirements. When installing the sealing strip, it should be elastic to prevent the sealing strip from falling

(4) use special solvent or cotton yarn dipped in dry water to clean the dirt on the surface of the doors and windows. The remaining traces of the filled sealant should be cleaned up in time, and the surface of the aluminum alloy doors and windows should not be scratched, and the appearance of the completed aluminum alloy doors and windows should be neat and beautiful
