Truss structure engineering

With the development of the construction industry and people’s continuous pursuit of architectural modeling and architectural span, a new type of building structure – steel truss structure came into being. Steel truss structure with its stable structure, flexible shape, convenient construction, light and gorgeous appearance, can meet the requirements of large span is widely used in all kinds of large sports exhibition venues, stations, airports and steel trestle and other public buildings and facilities. Steel truss structure has the prospect of widespread application.
Steel truss structure is a new type of structure developed on the basis of steel grid structure, mainly in the form of circular steel truss, but also can be made of other arbitrary shape of steel. The pipe truss members are welded and combined in the form of intersecting lines, and the structural nodes do not need to transition through the spherical nodes, so the stability of the structure is improved, the materials are saved, and the construction cost is reduced.
Because the shape of the end section of the pipe truss is very complicated, it must be automatically cut by special precision machinery, so as to effectively ensure the processing quality of the components. For components with radian requirements, special automatic equipment is generally used for hot bending processing, and its radian, curvature and other technical indicators can be highly guaranteed. At the same time, in the anti-corrosion function, because the joints of the pipe truss structure are all closed welding, it also effectively makes up for the common problems and drawbacks of internal corrosion caused by the loose sealing of the joints of the bolt and ball structure.
The construction of steel truss structure is difficult, and the requirements for construction site, structure positioning, on-site welding technology and construction personnel quality are high. The guarantee of engineering quality mainly depends on the quality of on-site construction. Therefore, the management of site construction is of great importance. The construction methods of pipe truss structure mainly adopt the way of ground unit assembly, aerial assembly or ground assembly, and overall lifting.
