What are the advantages and disadvantages of the three steel structure connection methods

Time:[2022-12-28]  Hits:1469

The connection methods of steel structure can be divided into welding connection, rivet connection and bolt connection. Welding is the most widely used. High strength bolt connection has developed rapidly in recent years and is used more and more. Rivet connection has been basically replaced by welding and high-strength bolt connection, and is rarely used. Each of the three connection methods has its advantages and disadvantages. This article mainly introduces the advantages and disadvantages of the three connection forms of steel structure connection.


First, the steel structure connection methods include welding connection, riveting connection and bolt connection.

 


Advantages and disadvantages of the cohesion method:


1. The advantages of rivet connection are: good plasticity, resistance and integrity, small connection deformation, reliable force transmission, good fatigue performance when bearing dynamic load, and easy quality inspection, especially for heavy and directly bearing dynamic load structures. The disadvantages of rivet connection are: complex structure, large amount of steel, troublesome construction, loud noise during large riveting, and poor working conditions. At present, it is almost not used in the project.


2. Welding is the most important connection method for steel structures. The advantage is that any shape of structure can be connected by welding, which is simple in structure, saves labor and materials, and can realize automatic operation with high production efficiency. No need to punch, saving labor and time. The air tightness and water tightness are good, the structural rigidity is large, and the overall performance is good. The disadvantage of welding connection is that there is a heat affected zone near the weld, and the material will become brittle. The residual stress of welding will make the structure vulnerable to brittle failure, and the residual deformation will change the shape and size of the structure. Once the welding crack occurs, it is easy to expand.


3. Advantages of bolt connection: simple construction process, convenient installation, suitable for site device connection, can better ensure project progress and quality. The utility model has the advantages of plastic connection, good resistance, reliable force transmission, convenient disassembly of the device, repeated use, and small connection deformation. Disadvantages of bolt connection: because the opening will weaken the section of the component to a certain extent, and the connected components need to be overlapped, or additional connecting components such as connecting plates and angle steel are added, so there are many consumables.


In conclusion, the steel structure connection is crucial in the steel structure construction project. It can be said that it is the lifeblood of the overall steel structure building, and is directly related to the stability of the steel structure building. Therefore, it is essential to master the steel structure connection method. It is also necessary to understand the advantages and disadvantages of the three steel structure connection methods: welding connection, bolt connection, and rivet connection.
