The curtain wall aluminum profile keel is a structural stress part for supporting a curtain wall, and is usually made of aluminum alloy, so that the aluminum alloy has the characteristics of good straightness, high strength, light weight and the like, but the bending performance of the aluminum alloy is extremely poor (large radian hot bending can be realized, but the curtain wall effect is often influenced). Aiming at the special-shaped curtain wall, main keels (upright columns and cross beams) of the curtain wall are not on the same curve (straight line or arc line), but are broken off at the middle part to form corners. The curtain wall keel stress conduction needs rigid connection at a breaking point, but the aluminum alloy material does not have bending performance, can be cut into two sections only, and is connected at a breaking point through other connecting pieces. At present, the common method is to add a steel adapter at the breakpoint of the aluminum alloy keel for switching or directly adopt steel materials, and the steel materials have weldability, strong rigidity and high strength and are suitable for switching at any angle.

However, the steel adaptor has the following disadvantages:

1. the steel and the aluminum alloy belong to different metals, the direct contact is easy to generate electrostatic corrosion, and an insulating gasket is required to be arranged between the steel and the aluminum for separation, so that a gap is increased between the steel and the aluminum, and the connection rigidity and the connection precision are not easy to control;

2. the steel material is easy to rust and perishables, and has potential safety hazard for a long time;

3. the welding precision of steel is difficult to control, and the precision quality of the curtain wall can be directly influenced;

4. the steel connecting piece is subjected to rust-proof galvanizing treatment, so that the environmental pollution is caused, and the environment is not protected;

5. the steel has high strength, heavy weight, difficult processing, large processing error and difficult production and assembly;

6. if stainless steel is adopted, the rust defect can be avoided, but the price is high and the cost is too high.
