Belong to corrosion；Capturing position when blank size and the crooked radian installation of aluminium alloy transom, all aluminium alloy transom connectors are equal
Setting is in T-type keel position, and thus effectively avoids transom connectors in space, simplifies working procedure and has saved aluminium
The dosage of alloy-junction profile；
The completion line that aluminium alloy transom is put after the completion of just filling according to ground is adjusted the disengaging of transom, disappears as far as possible
Except the error generated by installation；Bolt is fastened after integrated regulation；Aluminium alloy transom is erected after the installation is completed
Installation to aluminium alloy carinula, the fixation keel as subsequent fabric；Dedicated fixed dragon because of vertical carinula as fabric
Bone, therefore should be noted when installing centre keel and avoid generating difference of height with transom；
E, fabric is installed
It is lateral in bamboo aluminum composite plate that aluminium alloy joist designs typesetting and Fabric Design width after the installation is completed, according to bamboo aluminum composite plate
Fabric keel clamp is installed, fabric clamp keel radian should be identical as lateral aluminium alloy joist radian, fabric clamp peace at gap
Fabric is installed, fabric installation requirement is tightened, is smooth after dress；
F, bamboo aluminum composite plate is installed
Fabric carries out bamboo aluminum composite plate installation after the installation is completed；Bamboo aluminum composite plate epidermis is natural bamboo skin, and color should be carried out before installation
Bamboo clappers similar in color is mounted on same panel region and pays attention to the transition of color by difference than choosing, reduces color difference to decorative effect
It influences；The installation of bamboo aluminum composite plate uses outer wall stone back bolt type dry-hanging method, and the installation of the every row of bamboo aluminum composite plate is arranged according to design
Version starting point starts to install to two sides, carries out from lower to upper, first installs big face, then install corner part, it is ensured that every block of plate is perpendicular
Verticality in projection；
G, the closing in of bamboo aluminum composite plate and review adjust
Inspection check will be carried out by often installing one section, avoid deviation accumulation；Guarantee that entirety is bi-curved smooth, transverse joint will guarantee
Levelness and width degree；
The smooth of curved surface can be adjusted by L-type aluminium alloy pendant, and transverse joint width degree can be by back of the body bolt pendant
Adjusting screw carries out up and down adjustment.
