Profile Cross-Section Design
The cross-section design of aluminum profiles for curtain walls needs to consider multiple factors, such as the structural form of the curtain wall, stress conditions, and installation method. Common profile cross-sections include rectangular, square, and circular. Different cross-sectional shapes have different mechanical properties and usage characteristics. For example, rectangular profiles have better stability when subjected to horizontal forces and are often used for curtain wall columns and beams.
The internal structure of the profile also affects its performance. Some profiles are designed with internal reinforcing ribs to improve the strength and rigidity of the profile. The number, location, and size of the reinforcing ribs need to be optimized according to specific design requirements.
Connection Design
There are various connection methods between aluminum profiles for curtain walls, such as bolted connections, welded connections, and riveted connections. Bolted connections are the most common connection method, offering advantages such as convenient installation and disassembly. In bolted connection design, factors such as bolt specifications, quantity, and tightening torque need to be considered to ensure the reliability of the connection.
Welded connections can form a strong whole between profiles, but the welding process generates thermal stress, which may affect the performance of the profile. Therefore, appropriate measures need to be taken to control thermal stress during welding design and construction, such as preheating and slow cooling. Riveting connections are suitable for some parts where the connection strength requirements are not high.
