Description

TECHNICAL FIELD

[0001] The present application relates to the field of architectural decoration, in particular to a forming method of large-area double-curved aluminum decorative plate. BACKGROUND

[0002] In the prior art, large-area aluminum plate installation is usually fixed on a steel skeleton by traditional self-tapping screws. Keel bending and panel bending are required to form the final double curve, and both bending processes will form bending deviation (there are two installation and positioning deviations), which increases the installation error of the keel panel, increases the installation and adjustment difficulty, and causes the installation curve to be not smooth. During construction, the keel is installed first, and then the panel block is installed, which requires two high-altitude operations, two line laying, and two adjustments. The installation deviation of the keel causes a large adjustment amount of the panel installation and increases the installation difficulty. If the keel is recessed, the adapter needs to be increased, and if the keel is convex, the installation space of the panel will be occupied, which requires customizing the adapter, increasing the adjustment space, and the convex keel will directly cause the panel to be unable to be installed, and the panel curvature needs to be changed during installation. Changing the panel curvature requires replacing the panel or making the convex keel recessed, which affects the installed panel and makes the panel difficult to install. Moreover, most of them do not realize full assembly installation, and the aluminum plate surface often appears uneven due to welding deviation of the steel skeleton. The hoisting and construction of large-area aluminum plate is difficult. The traditional steel pipe is used for bending to make the first keel of the curtain wall, and the keel will rebound during bending, causing the bending curvature to not meet the design requirements. In order to eliminate the installation deviation of the keel, adjustment needs to be made on the panel, the aluminum plate is spliced, the curvature of the curved surface is difficult to control, and in some places, the uneven splicing angle is caused to eliminate the secondary adjustment and installation deviation of the panel, which affects the installation quality and appearance. In order to solve these problems, different installation solutions have appeared in the industry, and various unsatisfactory places often appear during installation. Especially for large-area double-curved aluminum decorative plate installation and construction, not only is the installation difficult, there are welding deviation, bending steel pipe rebound deviation and other quality problems, but also three-dimensional adjustment is difficult, and finally it is difficult to form a smooth and smooth double-curved decorative effect.
