MATERIAL OF WELDED BALL NODE

 

The material of Bolt Ball Node uses 2 round steel plates (Q235 or Q355) are welded after hot or cold-pressed into two hemispheres.

CHARACTERISTIC OF WELDED BALL NODE

The advantages of the welded ball node are clear force transmission, simple structure, beautiful shape, convenient connection and adaptability in the space frame construction. This node is suitable for connecting round steel pipe, as long as the steel pipe cutting surface perpendicular to the axis of the steel rod can be in the hollow sphere on the natural alignment without eccentricity. As the sphere is not directional, it can be connected with the rod in any direction, and its advantages are more prominent when there are more converging rods. Once, it is highly adaptable and can be used in all forms of netting structures.


The disadvantages of the welded ball node are: a larger amount of steel, Node steel consumption accounts for 20%-25% of the total steel consumption of the grid.; stamping welding labor, high welding quality requirements, field welding accounts for a large proportion; rod under the material requirements are accurate; when the welding process improperly caused by welding deformation is too large after difficult to deal with.

INSPECTION OF FINISHED WELDED BALL

The surface of the welded ball should be smooth and flat, no ripples, local unevenness is not greater than 1.0mm, the weld height and ball flush deviation is not greater than ± 0.5mm, the ball diameter deviation is not greater than 2.5mm, the ball roundness deviation is not greater than 2.5mm.

SAFS devote to the development of space frame for several years, professional manufacture of space frame for diverse projects such as aircraft hangar, bulk storage, warehouse and skylight roof, etc.

In what areas are steel structures usually used

-

Steel structure manufacturers can process a wide variety of products, including the following categories: 1. Single and multi-story industrial and residential buildings. 2. Office buildings, primary and secondary schools, hospitals. 3. Luxury villas, tourism buildings. 4. Modern commercial buildings for various markets. 5. Mobile buildings (demountable buildings, emergency projects). The main building materials in membrane structure engineering are steel and membrane materials. For steel structures, the main processing flow includes: material feeding → cutting → inspection → assembly welding → rust removal → numbering packaging → factory. The precautions are: 1. Materials must have a material certificate. 2. According to the cutting length and rod specifications calculated by the designer, the rods are classified and stacked for easy construction in the next step. 3. According to the penetration size of the steel pipe, considering the influence of wall thickness and groove, the automa

Three Methods of Space Frame Installation

  What are the 3 methods of space frame  installation ? SAFS steel structure professional technical staff share with customers and friends:   1.  Splicing the entire space frame  directly, after the completion  of  the corresponding ceiling method to hoist the entire space frame  into the air, and then within a certain hovering time, weld the space frame  in the corresponding position and connect it with the whole  building . This method is faster  to install, but has higher requirements for operators. 2.  The method is relatively mild, the space  frame works directly at a high place, and the space  frame is installed bit by bit through the part that intersects with the building, that is, starting from the surrounding area and completing the work at the final center point. The schedule  is very slow, but the operation difficulty is also reduced a lot. 3. This method is mainly applicable to the quadrangular pyramid structure and the triangular pyramid structure. Each vertebral structure

  Coal storage facilities, including coal storage sheds, dry coal yards, and coal storage warehouses, have always been crucial in the coal industry. The application of steel structures and space frame technology is redefining the future of these coal storage facilities. These technologies not only enhance coal storage efficiency but also improve facility performance and sustainability. Challenges of Coal Storage Facilities: Coal storage facilities need to store large quantities of coal while ensuring it remains dry and of high quality. Traditional coal storage facilities often face issues such as coal dust emissions, inadequate humidity control, and maintenance difficulties. The application of steel structures and space frame technology offers new solutions to address these challenges. Advantages of Steel Structures: Steel structures play a pivotal role in coal storage facilities. Their high strength and flexibility make them an ideal material for supporting large-scale coal storage
