Weld-Free and Worry-Free: Redefining Structural Efficiency in High-Seismic Regions

图片
 For contractors weary of labor-intensive, time-consuming structural installations—especially in high-seismic zones— bolted steel framing offers a solution that radically redefines safety standards. Its core advantage? A design that guarantees ease of assembly without sacrificing seismic performance, streamlining on-site workflows while meeting every compliance requirement. The days of project delays caused by on-site welding, tedious alignments, or bulky reinforcement are over. Bolted steel components are prefabricated, precision-cut, and pre-drilled, ready for assembly straight off the truck. The intuitive bolting system requires no specialized skills for installation, allowing crews to erect frames with rapid precision, significantly cutting down installation time compared to rigid structures like concrete. No more worrying about mismatched parts or labor-heavy phases—this system is built for high-speed execution, even under the toughest site conditions. But simplicity doesn’t ...

Application and Installation of Bolted Ball Grids in the Design of Large-Span Roof Structures

图片
 Large-span roofs are a common structural form in modern buildings and are widely used in large-scale public buildings such as stadiums, exhibition centres and airport terminals. In these projects, the structural design should not only meet the functional requirements, but also take into account the economy, aesthetics and construction feasibility. As an efficient space grid structure, bolted ball space frame is widely used in large-span roofing projects due to its advantages of light dead weight, strong bearing capacity and convenient construction. I. Structural design characteristics of bolted ball grid frame Bolted ball mesh rack is a kind of three-dimensional space  structure composed of ball nodes and rods, and its core feature is to connect the rods and ball nodes through bolts to form an overall force system. Compared with traditional steel joist, bolted ball grid has the following structural design advantages: Light deadweight: the rods of bolted ball space struc...
