Steel structure joints are very important in steel structure buildings

We know that steel structure will not have good corrosion resistance when used, steel structure many people can be a little worried when choosing steel structure, but in fact, we do not need to worry, because steel will be sprayed in the production process. Steel spraying adopts zinc, aluminum or zinc aluminum alloy and other materials that are not easy to corrode. This technology melts zinc through heat source, and then melts the metal material. At this time, metal particles can be sprayed on the steel surface, forming a thick metal protective layer on the steel surface. The protective layer can not only play the role of physical isolation, but also avoid all kinds of adverse effects of steel structure as far as possible, so the protection of the just is very great.

Generally speaking, there are two spraying methods for thermal spraying treatment: arc and flame. These two methods make up for the various shortcomings of the previously used hot dip zinc treatment methods, and the tank size and steel size do not affect the spraying effect. And, after the test, we can choose to spray alloy coating steel. After comparison, we will find that the protection effect is better than only a single coating steel. Therefore, in the actual use process, the alloy coating for steel protection and corrosion resistance is very good.

Nodes are very important in steel structure buildings. Nodes can ensure that the building will not be deformed when stressed, and can ensure that the building is in a relatively stable state. Therefore, nodes occupy a very important position in the building.

1. Semi-rigid node. It is a node between a rigid node and an articulated node. It not only has a certain bending moment to bear force, but also shape. This kind of node has good bending ability to ensure the stable bearing capacity of the building. And the semi-rigid structure can also improve the building's seismic capacity and bending capacity, is a kind of connection between the rigid and flexible.

2, the rigid node can ensure that the building stress process, the beam-column Angle for a long time to maintain no deformation or only slight deformation of the node. Normally, the connection strength of rigid joints of steel structures is often greater than the yield strength of connected members, so how to control the stability and strength of joint connections is very important. If you want to have a stable performance, then it is necessary to ensure that the Angle of the node and the beam and column structure will not change as much as possible when the force is exerted, so that the structure of the building can remain stable for a long time.

3. Articulated connection node. Articulated connection node is generally used for beam and column body, column foot fixed end of the fixed, so that the building remains stable, the bearing capacity of the end can be strengthened to ensure the stability of the building.
