It can be divided into double -layer space frame -type space frame manufacturer structure, single -layer and double -layer shell -type space frame structure. The rods of the plate -type space frame and the two -layer shell -type space frame are divided into upper rods, space frame abdominal rods and abdominal rods. They are mainly responsible for tensile strength and pressure. In addition to the tensile strength and pressure, the rod of the single -layer shell -type space frame also bends the curved distance and cut force. The space frame processing industry base has mastered most of the space frame structures in my country. Three categories of important divisions:
Class 1: space frame processing is composed of the structure system of the general floor graphic arranging frame. There are two -way orthogonal and positive space frame, two -way orthogonal and oblique space frame, two -way angle sloping space frame, and three -way space frame;
Class 2: The processing of the space frame frame consists of a quadrocrocleauty cone control module with a quadrilateral cone space frame, a quadruple cone space frame, an oblique four -corner cone space frame, a checkerboard rigid cone space frame, and a star -shaped quadrior.
Class 3: consisting of triangular cone control module. There are three methods: triangular cone space frame, triangular cone space frame, and honeycomb -shaped triangular cone space frame. The shell -type space frame structure is divided into an important part of the shell -type space frame, the oblique shell -type space frame, and the hyperbolic parabolic shell -type space frame according to the shell. The space frame structure is composed of steel space frame, concrete constructor space frame, and steel and concrete structures according to common raw materials. In the production and processing of space frame shelf, the steel space frame is used more.
The cross section of the space frame processing structure shall be established based on the tensile strength and stability. In order to reduce the computing length of the pressure rod to improve its stability, preventive measures such as adding and fixed brackets can be adopted. Nodes of plate -type space frame space frames and double -layer shell -type space frames made of stainless steel profiles are mainly crossboard nodes, welding welding empty ball nodes and bolt ball nodes.
Cross -board nodes are suitable for the space frame structure of the gap steel rod, the connection between the rod and the node board, and the welding welding or high -strength bolt is used. Hanged ball nodes and bolt ball nodes are suitable for the space frame structure of seamless pipe rods. The node of the single -layer shell -type space frame should be bent. Under normal circumstances, the steel consumption of nodes accounts for 15-20%of all steel space frame structures.
