the line should be measured and placed first, according to the site datum line, after reviewing the line without error.
It is necessary to use the latitude and longitude meter to set out the vertical grid bus on the external surface of the aluminium composite panel,
and use the wire line on the fixed steel bracket as a sign control line to put out the centre line of each grid.
Then the level meter and standard steel tape measure, etc.,
in the wire line measured out the point barge aluminium composite panel horizontal grid point and do on the mark line.
After positioning, the control points are checked regularly to ensure that they are in the correct position.
Also will be connected to the main structure on the pre-buried parts welding fixed, when the main structure is not buried on the pre-buried iron,
it can be in the main structure on the hole, installation of expansion bolts and connection iron fixed.
Use rivets or bolts to fix the aluminium composite panel finish on the steel skeleton piece by piece according to the construction drawing,
paying attention to the 10-15mm gap between the panel and the board in order to adjust the installation error,
and the deviation of left and right, top and bottom should not be more than 1.5mm when installing the aluminium composite panel.
