Space Frame Product Description

The space frame is an important branch of the spatial structure system. It constructs an architectural structure form that combines stability and aesthetics through the orderly connection of three-dimensional spatial rods. Currently, commonly used grid forms include bolt-sphere grids and welded-sphere grids. Bolt-sphere grids are assembled and connected through bolt spheres, bolts, sleeves, conical heads, and rods, while welded-sphere grids are welded and connected by hollow spheres and rods. This structural form is widely used in various industrial and civil buildings.

Production Technology

7jian Steel Structure adopts a digital intelligent manufacturing production line, including intelligent CNC laser cutting machines (with a maximum cutting thickness of 60mm), automatic track-type welding robots, automatic crawler-type welding robots, large gantry welding machines, and large component straightening machines. The butt fusion weld can meet Grade I standards, and the perpendicularity and flatness of the components are superior to the current national standard of China, “Code for Acceptance of Construction Quality of Steel Structures” (GB50205). The surface of the components is treated with shot blasting for rust removal, with a rust removal grade of SA2.5. The components can be protected against corrosion using paint spraying, hot dip galvanizing, and other anti-corrosion processes, with a corrosion protection period of over 15 years.

Applicable Scenarios

The applicable scenarios include buildings requiring large-span coverage, such as factories, gas stations, toll stations, coal sheds, and stadiums. For instance, the coal shed space frame can achieve a column-free space with a span exceeding 50 meters, meeting the operational needs of large equipment. In addition, places with high structural stability requirements, such as high-speed rail stations and logistics parks, often adopt this type of structure
