Intersecting Node Space Frame

Details

Tubular trusses are spatial steel structures formed by assembling steel members—such as circular, square, or rectangular hollow sections—using methods like intersecting-line welding or bolted connections. Unlike standard space frames, the main chords and branch members of a tubular truss are welded directly to one another without gusset plates; this facilitates the creation of visually striking forms, such as circular arches and complex curves.

Product Advantages:
1. Mechanical Performance: Members are subjected only to axial forces, eliminating additional bending moments. The spatial truss configuration provides bi-directional or tri-directional stiffness, offering outstanding resistance to wind, seismic activity, and thermal deformation. It effectively prevents issues common in traditional structures, such as bending, out-of-plane buckling, and torsional instability.
2. Cost Efficiency: Steel consumption is reduced by 20%–35% compared to traditional solid-web beams or planar steel trusses. This fundamentally solves the problem of spiraling lifecycle costs caused by the low material utilization rates of traditional structural systems.
3. Construction Schedule: Members and joints undergo CNC intersecting-line cutting and robotic welding at our factory, allowing for direct on-site assembly. This eliminates traditional steel construction issues-such as inconsistent weld quality, poor dimensional accuracy, high-altitude work risks, large site footprint requirements, and unpredictable timelines-thereby shortening your construction period by 30%–50%.
4. Design Aesthetics: The open, airy grid of members offers visual appeal and easily accommodates curved, folded, or free-form geometries. This eliminates the need for difficult compromises between spatial utility, aesthetic vision, and cost control.

Intersecting node space frame structures, due to their advantages of large span, lightweight and high strength, and design flexibility, are widely used in large public buildings with high demands on space and aesthetics:

1. Large sports venues: Gymnasiums, swimming pools, and stadium canopies (roofs) are typical applications. For example, the main steel structure of the National Stadium "Bird's Nest" is a complex box-section intersecting node truss.

2. Transportation hubs: Large roof structures of airport terminals and high-speed rail stations. These require creating open, column-free spaces.

3. Cultural and exhibition facilities: Theaters, concert halls, museums, and exhibition centers. Their design capabilities perfectly match architectural creativity.

4. Commercial and industrial buildings: Large commercial atriums, pedestrian street skylights, aircraft hangars, large warehouses, etc.

5. Landscape structures: City landmark sculptures, landscape towers, gates, etc., utilizing their expressive design capabilities.

6. Other special structures: Large coal conveying trestles, crane trusses, etc.
