In the field of modern engineering and construction, structural rivets play an indispensable role as a key component of connecting materials. Structural rivets are widely used in many fields such as construction, bridges, aerospace, etc. due to their excellent mechanical properties, corrosion resistance and easy installation.

1. Types and characteristics of structural rivets
Structural rivets are mainly divided into several types, including standard rivets, expansion rivets and special shape rivets. Standard rivets are usually used for general connections and have high strength and good durability; while expansion rivets are suitable for occasions where they need to be fixed in larger apertures and can provide stronger holding force.

Different types of structural rivets also have different choices in materials, such as aluminum alloy, steel and stainless steel. These materials give rivets different performance characteristics. For example, aluminum alloy rivets are light and corrosion-resistant, suitable for aerospace; while steel rivets are often used for the connection of heavy structures due to their high strength.

2. Installation method of structural rivets
Structural rivets are usually installed by cold riveting or hot riveting. Cold riveting is suitable for most metal materials, which can effectively reduce the thermal deformation of the material and ensure the strength of the connection. Hot riveting is suitable for specific occasions. Although its strength is high, it is necessary to control the temperature to avoid embrittlement of the material.

During installation, it is very important to ensure that the hole diameter of the rivet matches the size of the rivet to ensure the firmness of the connection. At the same time, the length and diameter of the rivet should be reasonably selected to avoid insufficient structural strength caused by the rivet being too short or too thin.

3. Future development trend
With the development of new material technology, the application field of structural rivets is also expanding. In the future, with the popularization of composite materials and high-performance alloys, structural rivets will be more used in the design of lightweight and high-strength structures. At the same time, the introduction of intelligent manufacturing technology will also improve the production efficiency and precision of rivets.
