![]() Hollow ball nodes and bolted ball nodes are suitable for the grid structure of steel pipe rods. ![]() Among them, the cross plate node is suitable for the grid structure of the section steel member, and the connection between the rod and the node plate adopts welding or high-strength bolts. The cross-section of the members of the steel grid structure should be determined according to the calculation of strength and stability. In order to reduce the calculated length of the compression rod and increase its stability, measures such as adding sub-rods and supporting rods can be adopted.įor plate-type grid structure and double layer shell-type grid structure, the nodes come in three forms: cross-plate nodes, welded hollow ball nodes and bolted ball nodes. Know More About Grid Rod And Node Structure In industrial buildings, large-span roof grid structures are increasing, such as aircraft assembly workshops (spans generally above 60m), warehouses with spans of 50-60m in automobile assembly, and large-scale laboratories with a span of about 50m and a height of about 40m in the electrical industry. The grid structure is light and handy, and can be designed into various shapes, whether it is a building plane or a space curved shape.Ĭommon Applications of Grid Steel Structureĭue to the many advantages of grid structures, more and more fields choose steel structure grid construction, such as the large-scale gymnasium roof grid frame and stadium awning.And also the on-site installation is simple and does not require large-scale machinery and equipment. ![]() The components of the grid structure are mostly the same in size and shape, and can be mass-produced in the factory.
