The advantages of reticulated shell

The structure of reticulated shell can be classified according to the arrangement of the rods: single-layer reticulated shell and double-layer reticulated shell. Generally speaking, single-layer reticulated shell can be used for small span (generally below 40m), and double-layer reticulated shell can be used for large span. Due to less bars, light weight, simple node, convenient construction, single-layer reticulated shell has a better technical and economic indicators, but single-layer reticulated shell surface has a poor external stiffness and stability, a variety of factors will affect the internal force and deformation of the structure obviously. Thus it should be noticed including, the layout of structure bar, roofing materials choosing, the determination of calculation mode, implementation of structural measures, construction and installation of the structure.



a. The bars of reticulated shell structure mainly bear axial force, and the distribution of internal force is relatively uniform, with a small stress peak, so the effect of material strength can be given full play.

b, Because it can adopt various curved forms of shell structure, it can be similar in appearance to the thin shell structure which has rich style. Whether it is a building plane or a building form, shell structure can give designers with full freedom and imagination, by the comparison of moving and static, light and dark, virtual and real of the steel structure, combination of architectural beauty and structural beauty makes the building easier to coordinate with the environment. 

c. In the shell structure, a straight bar can be used instead of a curved one, that is, with folded surfaces instead of curved surfaces. If the rods are arranged and constructed properly, they can have good mechanical performance similar to the thin shell structure. At the same time, it is convenient for factory manufacturing and site installation, and has the same advantages as the flat grid structure in structure and construction methods.

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", ...

Types of steel space frame structure roof

图片
  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 ....

Space frame dome structure

图片
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.
