What are the connection methods of steel structure?

There are three kinds of connection methods for steel structure: weld connection, bolt connection and rivet connection.

1, weld connection

Weld connection is through the heat generated by the electric arc to make the welding rod and the weldment partially melted, and condensed into a weld by cooling, so as to connect the weldment into one.

2, bolt connection

Bolt connection is through the bolt fastener to connect the connectors into one. Bolt connection is divided into ordinary bolt connection and high-strength bolt connection two kinds.

Advantages: construction process is simple, easy to install, especially suitable for site installation connection, but also easy to dismantle, suitable for the need to install and dismantle the structure and temporary connection.

3, riveted connection

Riveted connection is one end with a semi-circular prefabricated nail head rivets, the nail rod will be burned red and quickly inserted into the nail holes in the connector, and then rivet gun will be riveted into the other end of the nail head, in order to make the connection to achieve the fastening.

Expanded Information

The prefabrication of steel components in accordance with the order of installation and process requirements in the steel platform for the prefabrication and assembly of steel components to ensure the quality of welding production.

The splicing of steel sections should be more than 200mm between the splicing joints of the wing plate and the splicing joints of the web plate. The splicing length of the wing plate should not be less than 2 times the width of the plate; the splicing width of the web plate should not be less than 300㎜, and the length should not be less than 600㎜. In order to weld conveniently and ensure the welding quality, try to weld the reinforcing plates, connecting plates, pads, picket beams (girders), etc. on the ground steel platform according to the size of the construction drawings.

In addition to the prefabricated steel components on the steel platform according to the construction drawings and specification requirements for the production and assembly, should also consider the craftsmanship of the field installation and installation of dimensional changes.
