[China Aluminum Industry Network] 1 Measuring and Discharging Wires (1) Due to the large allowable errors in civil construction, the construction of honeycomb aluminum construction requires high accuracy, so it is not possible to completely rely on the civil horizontal baseline, and must be re-measured from the reference axis and the leveling point. Correct the review.

(2) Determine the curtain wall positioning line and the ruled line position on the ground floor according to the design.
(3) Use the theodolite or laser vertical instrument to guide the positive and negative angles of the curtain wall, and use the steel wire fixed on the steel bracket as the mark control line.
(4) Use the spirit level and standard steel tape measure to draw the level line of each layer.
1) Determine the midline of each facade.
2) The measurement error of distribution should be controlled during measurement, and the error cannot be accumulated.
3) Measurements should be carried out under conditions where the wind force is not greater than 4 and measures for avoiding wind are to be taken.
4) Check the timing of the control line after positioning the line to ensure that the verticality of the honeycomb aluminum curtain wall and the position of the metal mullion are correct.
All facade decoration projects should be based on the same baseline, and pay attention to construction cooperation.
2 Installation of the column The column is first connected with the connecting piece, and then the connecting piece is connected with the main body embedded part and adjusted and fixed. The deviation of installation elevation of column shall not be greater than 3mm, the deviation before and after the axis shall not exceed 2mm, and the deviation shall not exceed 3mm. The deviation of the installation elevations of two adjacent columns should not exceed 3mm. The deviation of the larger elevations of the same column should not exceed 5mm, and the distance deviation of two adjacent columns should not exceed 2mm.
