1. According to the shape of the truss, it is divided into: 1. Parallel chord truss (easy to arrange double-layer structure; conducive to standardized production, but the distribution of rod force is not uniform enough); The bending moment diagram of the lower simply supported beam, the rod force is evenly distributed, the material is economical, and the structure is more complicated); 3. Triangular truss (the rod force distribution is more uneven, the structure layout is difficult, but the slope meets the roof drainage needs)

The invention discloses a triangular steel tube truss structure which comprises upper chord members, lower chord members, structural web members, upper wind bracing web members, support legs, H-section steel and guardrails. Flanges are welded at two ends of each upper chord member, the upper chord members are connected with one another by bolts, flanges are welded at two ends of each lower chord member, the lower chord members are connected with one another by bolts, steel plates are welded on the upper chord members and the lower chord members respectively, flanges and steel plates are welded at two ends of each structural web member, flanges and steel plates are welded at two ends of each upper wind bracing web member, the structural web members are connected with the upper chord members and the lower chord members by bolts, the upper wind bracing web members are connected with the upper chord members and the lower chord members by bolts, the support legs are welded with the upper chord members, the H-section steel is connected with the upper chord members by bolts, and the guardrails are welded with the H-section steel. The triangular steel tube truss structure has the advantages that the triangular steel tube truss structure is reasonable, machining procedures can be reduced, the labor intensity can be lowered, the work efficiency can be improved, steel consumption can be decreased, and the production cost can be saved.
Description
technical field [0001] The invention relates to a triangular steel pipe truss structure. Background technique [0002] The ideal hinged system of straight rods that are only subjected to node loads is called a truss structure. It is abstracted and simplified by some engineering structures whose shafts intersect at one point. Trusses were first used in the construction of wooden bridges and roof trusses. Trusses can be classified according to different characteristics. 1. According to the shape of the truss, it is divided into: 1. Parallel chord truss (easy to arrange double-layer structure; conducive to standardized production, but the distribution of rod force is not uniform enough); The bending moment diagram of the lower simply supported beam, the rod force is evenly distributed, the material is economical, and the structure is more complicated); 3. Triangular truss (the rod force distribution is more uneven, the structure layout is difficult, but the slope meets the r...
