What are the forms of space frame?
Classified by space frame:
(1) Cross-plane truss system, including two-way orthogonal normal-laying space frame, two-way oblique crossing and oblique-laying space frame, two-way orthogonal and oblique-laying space frame, and three-way space frame;
(2) Quadrangular pyramid system, including: positive quadrangular pyramid space frame, positive evacuated quadrangular pyramid space frame, oblique quadrangular pyramid space frame, star-shaped quadrangular pyramid space frame, and checkerboard quadrangular pyramid space frame;
(3) Triangular pyramid system, including triangular pyramid space frame, evacuated triangular pyramid space frame, and honeycomb triangular pyramid space frame;
(4) Unidirectional broken-line space frame.
