– OverviewA space frame structure is a three-dimensional structural system made of steel tubes connected by spherical nodes. It is widely used in large-span roofs such as stadiums, airports, exhibition halls, and industrial buildings.Main Components1. Ball Node (Spherical Joint)The central steel sphere that connects multiple members in different directions. It distributes loads evenly across the structure.2. Top ChordThe upper horizontal members of the space frame. They carry roof loads such as cladding, wind, and snow.3. Lower ChordThe lower horizontal members that provide structural stability and balance tension forces.4. Web MembersDiagonal members connecting the top and lower chords. They transfer loads between the layers and create the three-dimensional strength of the structure.Grid Member DetailsSteel PipeThe main structural element forming the frame.Cone TipA conical connector welded to the steel pipe to connect with the ball node.SleeveA connecting piece between the steel pipe and the bolt.High-Strength Bolt (Grade 10.9)A high-strength bolt used to secure the member to the ball node.Sealing PlateA plate used to close the end of the pipe and protect it from moisture and dust.Advantages of Space Frame StructuresLightweight but very strongCapable of covering large spans without columnsFast installationFlexible architectural shapes
