Spherical grids are generally in the shape of triangular pyramids, triangular prisms, cubes, truncated quadrangular pyramids, etc., generally with bolt ball nodes, welded ball nodes, etc., which is a kind of indoor space frame.
Trusses generally have single and double row trusses, triangular trusses, and quadrilateral trusses. The trusses we often talk about are quadrilateral trusses, which are also the most used trusses. Common ones are steel trusses and aluminum alloy profile trusses.
Spherical grids can be supported nearby, with more support points, and the parallel bending stiffness is large, which belongs to the double bearing capacity management system.
Truss structure is a kind of plane structure that we often talk about. It must have support points such as bases and other external forces to form a warm structure. It is a unilateral bearing capacity management system.
Grid structure has the characteristics of light weight, high bending stiffness, good seismic resistance, etc. The disadvantage is that there are more components intersecting at the nodes, and the manufacturing and installation are more complicated than the plane structure.
The advantage of the truss is that the components mainly bear tension or pressure, which can make full use of the function of materials, save materials, and reduce the weight of the structure. It is developed on the grid structure. Compared with the grid structure, it has unique advantages and practicability, and the steel content of the structure is also relatively economical.
Grid structure, due to its node characteristics, is mostly used for inclined structures or tops, and can be used as the roof truss of buildings such as stadiums, cinemas, and waiting halls.
Steel trusses mainly bear radial tension or pressure, so they are suitable for stage layout, advertising stands, background stands, speaker and lighting stands, truss sheds, steel roof trusses, road bridges, crane stands, etc. Used for outdoor performances, exhibition booth construction, road bridge load-bearing and decoration design. Because some industrial plants have truss customization services, special specifications and curved trusses can be customized according to the truss industrial plant.
