[0002] As people's quality of life improves, the shape and structure of modern buildings are also developing towards diversification. The spatial special-shaped curved steel structure is favored by architects because of its unique structure with large span, good stability, complex and beautiful shape, and saving steel. During the construction of the spatial special-shaped curved steel structure, the nodes are usually located first, and then the rods are located through the nodes. The rods are connected to each other to form a spatial curved surface. Common nodes include pin crown welding balls, cylinders, etc. The nodes on one side of the spatial curved surface are made into node surfaces along the curved surface. To ensure the integrity of the spatial curved surface, the node surfaces are on the same spherical surface. Therefore, each node surface has a separate normal. In the past, the construction usually took the approach of finding three spatial points on the surface and determining the node surface through the coordinates of the spatial points. However, the operation process of the on-site workers in this scheme is cumbersome, the fine-tuning of the node surface is difficult, and the quality requirements of the installation team are high. It is difficult to adapt to large-scale rapid installation and construction. Therefore, how to quickly and accurately determine the orientation of the node surface has become the key to the construction of such spatial special-shaped curved surface structures, and it has become a technical problem that technicians in the relevant technical field need to solve urgently.

[0013] Furthermore, the node elevation positioning support is made of stainless steel round tube.

[0018] Step 4: Move the node elevation positioning support to the steel structure node installation point to determine the installation elevation and spherical center coordinates of the pin crown ball;

[0019] Step 5: Rotate the pin crown ball and use a level to make the top surface of the fixed cylinder level, so as to determine the installation slope of the node surface;

[0020] Step 6: Rotate the pin crown ball so that the fixed surface cylinder orientation line is parallel to the X-axis coordinate of the center of the pin crown ball.
