Testing standard of honeycomb aluminum plate

施工企业应根据幕墙的使用功能和耐久年限的要求，分别选用The thickness is10mm、12mm、15mm、20mm和25mmHoneycomb aluminum plate;The thickness is10mm的Honeycomb aluminum plate应由1mmthick front aluminum alloy plate,0.5～0.8mmThe thick back aluminum alloy plate and aluminum honeycomb bonding;thickness in10mmThe thickness of the front and back aluminum alloy plates of the above honeycomb aluminum plates shall be1mm。

(1)Due to the large allowable error of civil construction and the high precision of honeycomb aluminum plate engineering construction, it cannot completely rely on the horizontal baseline of civil construction, and must be re-measured by the reference axis and level point, and corrected and reviewed.

(2)According to the design, the curtain wall positioning line and grid line position are determined at the bottom layer.

(3)Use theodolite or laser verticator to lead the positive and negative corners of the curtain wall, and use the steel wire fixed on the steel bracket as the marking control line.

(4)Use a spirit level and standard steel tape to lead out the elevation line of each layer.
