Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a roof structure. Background Art

[0002] Planar orthogonal trusses have the advantages of simple design, wide applicable span range, good economy, good sense of space and visual effects, etc., and are therefore widely used in roof structures of large-span spaces such as gymnasiums, exhibition halls, and airport halls. Although plane trusses have many advantages, they are relatively insufficient in out-of-plane stiffness and torsional stiffness, resulting in poor lateral stability. Therefore, plane steel trusses usually use various supporting structures, including but not limited to diagonal braces, cross braces, etc., to increase the stability of the structure. However, when the above-mentioned supporting structures are used to achieve out-of-plane constraints, the upper chord and lower chord of the steel truss usually require diagonal braces or cross braces, respectively. This structural form has problems such as complex structure, high construction cost, and affecting the aesthetic appearance of the building.
