Highly determining factors in the manufacturing process of dome space frame
The steel space frame industry is widely used, and more buildings begin to adopt the dome space frame structure. The production height can refer to the following factors:
1. The point support space frame is much higher than the surrounding support space frame;
2. When the roof load is large and the space frame span is large, the corresponding grid height also needs to be selected higher;
3. The height of the Dome space frame is related to factors such as roof load, span, plane shape, support conditions and equipment piping;
4. When the pipe passes through the space frame design, the height of the grid must meet its design requirements;
5. When the plane shape is round, square or close to square, the height of the grid can be slightly lower.If it is a long and narrow plane, the height of the grid needs to be higher.
After hemisphere correction and cutting, bevel should be made, and the bevel angle and form should meet the design requirements.The ribbed hemisphere is different from the welded hollow spherical, so the important nodes of the steel space frame are generally arranged with Ribbed welded ball,There are many types of ribs, such as single assist, vertical double ribs, etc.,Therefore, the double-ribbed ball should be ribbed and welded before assembling.Please note that the height of the ribs cannot exceed the radius of the circumference, so as not to affect the assembly. When assembling the sphere, there should be a tire position to ensure the quality of the spher. When assembling the sphere, the assembly diameter and roundness of the sphere should be consistent.
The selection of the height of dome space frame requires scientific basis,How to control the height, among which the user’s needs can only be used as a reference. The value of the space frame design can be used as the basis for execution, strictly in accordance with the data operation, and the guarantee of the smooth progress of the space frame project.
