Description

Technical Field

[0001] The utility model relates to the technical field of trusses, and specifically relates to a stage truss. Background Art

[0002] A truss is a structure formed by connecting rods with hinges at both ends. A truss is generally a planar or spatial structure composed of straight rods with triangular units. The truss rods mainly bear axial tension or compression, so that the strength of the material can be fully utilized. When the span is large, it can save materials compared with a solid web beam, reduce its own weight and increase stiffness. The advantage of a truss is that the rods mainly bear tension or compression, which can give full play to the role of the material, save materials, reduce the structural weight. Commonly used trusses include steel trusses, reinforced concrete trusses, prestressed concrete trusses, wooden trusses, steel-wood composite trusses, and steel-concrete composite trusses.
