 BOLT BALL Space frame structure is a kind of structure connected by the node of bolt ball , so the bolt ball is the key component of the structure. In GB standard. the bolt ball is made of 45# steel with the diameter of 100mm to 300mm. Normally there are 3-12 holes in the bolt ball and each axial line of the bolt hole is through the center of the ball.

  Key advantages of Barrel Vault Space structures are: Cost Effective: One of the greatest advantages of using space frames in Barrel Vaults is that it is comparatively cost effective. Eco-friendly: These space frames are 100% recyclable. Therefore it is known to be eco-friendly. Flexible Structure Design: It is one of the most flexible and sturdy structures used for constructing commercial buildings and residential properties.   Light Weight: Due to the uniform material load distribution spatially the Barrel Vault space structure is light-weight.   Accuracy in Installation: Another Important feature of using Space frame is that there is a high degree of accuracy in the process of designing and installation of a space frame.

  Comparison of welded and bolted ball netting structures space frame Analysis in terms of quality assurance. 1, welded ball structure using hollow ball (material Q235 ordinary steel) and welded pipe on the site of the welding, by the temperature and wind speed, under the influence of the welding machine equipment and basic artificial manual, resulting in the material, positioning, welding process, error, low precision. The steel has stress deformation before and after welding, which is a safety hazard. The angle control between the various bars is not accurate after use, which can easily distort the bars and destroy the balance of force transmission. It is not possible to adapt to the requirements of shaped curves and oversized spans, and the quality is difficult to guarantee, so there are great limitations. 2、Bolt ball structure is made of solid ball (material 45# high strength steel) and high strength bolt (material 40Cr), which are closely jointed. The angle between the screw ...

  Bolt Ball Testing Methods bolt ball 1, bolt ball and manufacturing bolt ball nodes need materials, its varieties, specifications, performance, etc. should comply with national product standards and design requirements. Inspection methods: check the quality of the product qualified documents, Chinese signs and inspection reports, etc. 2 、 Bolt ball shall not have burn, crack and crease. Inspection method: Sample part of each specification of bolt ball, observe with 10 times magnifying glass and surface inspection. 3, bolt ball thread size and thread tolerance should be in line with the current national standard provisions. Inspection method: check a part of each specification of the bolt ball and measure it with a standard thread gauge. 4, bolt ball diameter, roundness, adjacent two bolt hole centre line angle and other dimensions and allowable deviation should be in line with the local steel structure acceptance regulations. 5 、 Inspection method: Sample a portion of each speci...
