Requirements for aluminum alloy casement windows

11. Frame mounted mullion

1) Equipment name: electric hand drill

2) Technical requirements: (1) select self tapping screws;

(2) The installation shall be firm;

(3) Feel the height difference with your hands. There should be no too big concave convex, and the gap should not be greater than 0.1mm ;

(4) The horizontal plane of the mullion and the horizontal plane of the frame should be in the same plane.

3) Operating points: screw the self tapping screw through the pre drilled hole and screw it into the mullion cavity with electric push instead.

4) Inspection method: check the height difference and gap with caliper and depth gauge.

12. Frame and fan hinge

1) Equipment name: electric hand drill

2) Technical requirements: (1) the hinge shall be installed firmly without looseness;

(2) The hinge should be parallel to the material type;

(3) When the window sash is opened, the weakening amount shall not be greater than 2-3mm;

(4) The upper and lower hinges should be in a straight line.

3) Operating points: first check the installation position, hinges, screw holes and other problems before installation.

4) Inspection method: (1) check the installation position with a box ruler;

(2) Use the steel plate factory to check whether the hinge is parallel to the material type.

13. Fan distribution

1) Equipment name: electric hand drill

2) Technical requirements: (1) after the hinge is installed, it should be opened flexibly without obstruction defects and noise;

(2) It depends on the fit gap between the profile and the hardware, such as: pressing around the fan and the outer frame

The joint surface is 6mm, and the allowable deviation is ± 1mm;

(3) Each leaf is equipped with two hinges;

(4) The gap between the fan and the outer frame shall not be less than;

(5) The hoisting force shall not be greater than 50N.

3) Key points of operation: compare it with the drawing first, and install it only after there is no problem at all.

4) Inspection method: (1) check the pressing surface with caliper;

(2) Use a feeler gauge to check the fit gap between the fan and the frame;

(3) The tube dynamometer detects the opening and closing force.

14. Frame handle

1) Equipment name: electric hand drill

2) Technical requirements: (1) the handle shall be installed firmly without looseness;

(2) Flexible opening;

(3) Keep the gap not less than (notch and handle are inserted);

(4) The upper and lower hinges should be in a straight line.

3) Operating points: screw in with screws and do not loosen.

4) Inspection method: (1) check whether the installation position is correct with a box ruler;

(2) Whether the installation is secure.

15. Lock point

1) Equipment name: electric hand drill

2) Technical requirements: (1) the lock point shall be installed firmly without looseness;

(2) Flexible opening;

(3) When the fan is opened, the fixed lock point and the movable lock point have a gap greater than 0.3 mm.

3) Operating points: screw in with screws and do not loosen.

4) Inspection methods: (1) check whether the installation is correct;

(2) Check the fit clearance with a feeler gauge.

16. Assemble glass batten

1) Technical requirements: (1) according to the light transmission size of the window, the height and width of the glass batten shall be assembled;

(2) The gap between the frame and the batten is less than, and the gap between the batten and the batten is less than;

(3) Glass battens with excessive gap between frame and batten cannot be used.

2) Key points of operation: first measure the size of the inner frame glass batten, cut the material according to the size, and install it according to the number.

3) Inspection method: check the gap between the frame and the strip and between the strip and the strip with a feeler gauge.

17. Finished product inspection

1) Technical requirements: (1) the corner gap is less than;

(2) Window frame size deviation ≤ 2000 > 2000

The dimension deviation of the opposite side of the window frame notch is less than 0.1, and the dimension deviation of the diagonal of the window frame notch is less than

(3) The fit gap of frame and leaf is ≤, and the allowable deviation of lap width is ±.

(4) The gap between the frame and the batten around the finished window should be even.

2) Operating points: check the overall dimensions with drawings.

3) Inspection methods: (1) check the overall dimension with a box ruler;

(2) Check the fitting clearance with a feeler gauge;

(3) Check the height difference with a depth ruler.

17. Finished product packaging of casement window

1) Technical requirements: (1) when packaging, it should be packed one by one;

(2) Use soft, acid-free materials.

2) Key points of operation: the package should be firm and not loose.

3) Inspection method: (1) try whether the package is loose and tight by hand;

(2) Check whether the materials used are reasonable.

This process standard is applicable to the installation of aluminum alloy doors and windows in industrial and civil buildings.
