Steel structures are widely used for their low price and reliable performance, with industrial and civil buildings being the majority. Here we offer a number of different ways of connecting steel structures.

Steel structure is a structure made of prefabricated materials (steel), processed into members through the factory and then assembled on site by the site. Therefore, the connection nodes between members and members are an important part of forming a steel structure and ensuring the safety and normal operation of the structure.

1. Connection methods of steel structures

(1).Weld connection

Connection method: the weld connection in the steel structure, mainly using electric arc welding, that is, in the connection of members, by the high temperature generated by the electric arc, the welding rod or wire placed in the welding part of the metal melting, and make the members connected together.

Application: Rigid connection (can withstand bending moments), in addition to the structure directly subjected to dynamic load, ultra-low temperature state, can be used weld connection.

(2).Bolt connection

Connection method: High-strength bolts are connected with special spanners to tighten the high-strength bolts and apply the required pretension to them.

Application: is a hinged connection (bending moment is zero) can be used in general, characterised by fast on-site work, easy to remove and easy maintenance.

(3).Rivet connection

Riveting method: riveted connection of the construction process, is first in the connected components, made than the nail diameter 1.0 ~ 1.5 mm hole. Then one end of the rivet with a semi-circular nail head heated to a cherry red, plugged into the hole, and then riveted with a rivet gun or riveting machine, so that the rivet fills the nail hole, and hit into another rivet head.

Applications: Used when the structure is under low stress.

2  . The characteristics of each connection method

(1).Characteristics of welding

①Simple construction – any shaped component can be directly connected without auxiliary parts.
②Saving work and materials – easy processing, no drilling of holes and no weakening of the cross-section.
③Quick construction – can be automated.
④ Good tightness of the connection, high stiffness and good integrity.

(2). Features of bolted joints

①Simple construction, easy assembly and disassembly, high requirements for installers.
②Friction type high-strength bolt connection power performance is good.
③ fatigue resistance, easy to prevent the expansion of cracks

(3).Characteristics of rivet connection

Plasticity, good toughness, good power performance.

In general, the connection is mainly welded connection, bolt connection, rivet connection these three, through the above content we also have an understanding, also hope to help you, including the advantages of several ways also to everyone sorted out.
