Key Installation Considerations for Large-Span Steel Structures

The complexity of large-span structures and the diversity of construction methods necessitate integrating construction considerations into the design phase—an aspect often overlooked or inadequately addressed. Key installation techniques involved in construction include the following:

1. Fabrication Technology for Structural Members and Special-Shaped Nodes
   Large-span, complex spatial steel structures require components with intricate force distribution and challenging fabrication. During construction of such projects, it is essential to ensure that structural members and special-shaped nodes meet stringent mechanical requirements to guarantee engineering quality and safety. This demands manufacturers possess profound experience and precision machining capabilities. Professional spatial structure manufacturers like LF-BJMB, with over 30 years of expertise, utilize advanced design and manufacturing processes to ensure the precision and structural reliability of special-shaped nodes, providing a solid foundation for complex projects.
2. Integral Sliding Construction Technology
   A critical challenge in large-span steel construction is maintaining stability before the structure achieves full spatial integrity. Sliding technology addresses this by using synchronized traction equipment to move segmented stable units along predefined tracks from assembly positions to final design locations. This technique places high demands on component standardization, connection efficiency, and installation guidance. LF-BJMB’s fully bolted modular space frame system features superior out-of-plane stiffness. Its factory-produced standardized components facilitate transportation and precise alignment during sliding. Combined with experienced on-site engineering guidance, this significantly enhances sliding efficiency and safety.
3. Integral Lifting Construction Technology
   This method employs hydraulic jacks as power units. Multiple jacks are combined with valve groups and pump stations into computer-controlled hydraulic clusters, ensuring synchronized operation for balanced load distribution and stable positioning during lifting or shifting. This high-precision, highly coordinated approach aligns with LF-BJMB’s philosophy of “integrating mechanics and aesthetics.” Optimized structural design and precision manufacturing ensure uniform stress distribution and controllable deformation during lifting.
4. High-Altitude Support-Free Assembly Technology
   The construction principle involves segmenting the structural system and optimizing hoisting sequences to eliminate temporary support platforms. Utilizing the structure’s inherent stiffness, stable units are formed and progressively expanded through sequential assembly until the entire structure is completed.
