The node is one of the cost-saving components of the grid structure, and it is also the main functional component of the flexible structure of the grid structure, especially the appearance of the bolt ball joint, which gives full play to the flexibility and reusability of the grid structure and the convenience of construction To the extreme. The editor of Jiangsu Huahai Steel Structure will introduce the nodes of the grid structure for you.

1) The nodes of the grid structure should be simple in structure, reasonable in force, clear in force transmission, easy to manufacture, easy to install and save materials, and try to make the bar's center of gravity lines converge at the node to avoid eccentricity.

2) The structure and connection of the nodes should have sufficient rigidity and strength. At the same time, the structure of the nodes should be consistent with the calculation assumptions as much as possible to reduce and avoid secondary stresses and internal forces caused by the grid members due to the unreasonable node structure. Change of number.
3) The connection nodes of the grid structure can be divided into welded steel plate nodes, welded hollow ball nodes, bolted ball nodes, steel tube cylindrical nodes or steel tube drum nodes according to their structural forms.
