The difference between space truss and space frame

Steel truss structure and space frame structure are common architectural structure forms, the same points of both are connected by building materials, what is the difference between the two?When are trusses used?When to use the space frame?
1. Common form of structure
The common shapes of the space frame are triangular cone, triangular body, cube, truncated quadrangle, etc. Generally, it has bolt ball node, welded ball node, etc., which is a kind of spatial structure.
Generally, trusses include single-row trusses, triangular trusses and quadrilateral trusses. The trusses we often say are quadrilateral trusses and are also the most commonly used kinds of trusses, such as steel structure trusses and aluminum alloy trusses.
2. Structural stress
The space frame structure can be supported around, multi-point support, large stiffness in the surface, belongs to the bidirectional stress system.
The truss structure is a kind of plane structure, which needs the support of external force such as the base to form a warm structure. It is a unidirectional force system.
3. Own characteristic
The space frame structure has the characteristics of light weight, large stiffness, good seismic performance, etc., but the disadvantages are that there are more bars on the joints, and the fabrication and installation are more complicated than the plane structure.
The advantage of trusses is that the rods mainly bear tension or pressure, which can give full play to the function of materials, save materials and reduce the weight of the structure.It is developed on the structure of the space frame, and it has unique advantages and practicability compared with the structure of the grid, and the amount of steel used in the structure is also more economical.
4. Application scope
With its node characteristics, the space frame structure is mostly used in the curved structure or the top, which can be used as the roof of the stadium, theater, waiting hall and other buildings.
Steel structure trusses mainly bear axial tension or pressure, so they are suitable for stage building, advertising frame, background frame, sound and light frame, truss frame, roof frame, bridge, crane frame and so on.Used for outdoor performance, exhibition building, bridge load bearing and decoration, because some workshops have customized truss service, special specifications and arc-shaped truss can be customized through the truss workshop.

Shape of steel space frame structure

图片
  The steel space frame  structure can realize various spatial regular shapes such as arches, circles, spherical shells, and saddle shapes, as well as various irregular shapes. Moreover, if the same shape and different structures are compared, the cost of the steel space frame  structure is relatively low. The shape of the steel space frame  structure refers to the regular or irregular changes in the three-dimensional shape of the grid. Due to the special structure of the space frame structure and the high-precision factory manufacturing requirements, the more precise components required for the complex space frame  shape can be processed in the factory. Through the subtle changes in the angle of the screw holes of the bolt ball joints and the changes in the length of the rods, the space frame  structure can be fitted to the complex shape requirements of the architectural modeling.  At present, the space frame structure has almost become "all-match", and all kinds of spatial

  Steel space frame  structure is widely used in various buildings, such as   stadiums, exhibition halls, high-speed railway station buildings, terminal buildings, large factories, etc.; steel space frame  structure is a large-span steel structure as the main structure; it has poles The parts have the advantages of reasonable force, light weight, good integrity and stability, large space rigidity, good seismic performance, beautiful appearance, and low cost. What are the main types of steel space frame  structures? The first type is composed of triangular pyramid units, and has three forms: triangular pyramid space frame , evacuated triangular pyramid space frame  and honeycomb triangular pyramid space frame . The second type is composed of a plane truss system, which has four forms: two-way orthogonal diagonally placed space frame , two-way orthogonally placed space frame , two-way diagonally diagonally placed space frame  and three-way space frame . The third type is composed of qua

Space frame dome structure

The space frame  dome uses a spherica l dome  as the main structural system, and the outside of the space frame is covered with plates or glass according to different needs. The glass dome can meet the lighting needs of the building. Natural light is filtered into the environment through the glass interface, making the building visually light and transparent. The space frame  dome uses a bolted ball space structure  as the main structure, and the covering material can be divided into blocks according to the size of the modular. Compared with the hyperboloid molding material, the cost is lower.
