Large span structure system

Various types of structures that span more than 60 meters of space laterally can be called large-span space structures. Commonly used large-span space structure forms include folded plate structure, shell structure, grid structure, suspension cable structure, inflatable structure, tent tension structure, etc.
The large-span space structure is one of the important symbols of the development level of national building science and technology. All countries in the world attach great importance to the research and development of spatial structure, such as international expositions, Olympic Games, Asian Games, etc. All countries use new spatial structures to demonstrate their own level of architectural science and technology. Spatial structure has become a measure of a country's architectural technology. One of the level signs.
 
 
1.FOLDED ROOF STRUCTUREUSAGE
An integral thin-walled folded-slab roof structure consisting of many reinforced concrete slabs connected into a zigzag shape. This folded plate can also be used as a wall of vertical members or other load-bearing members. The combination of folded-slab roof structure includes single-slope and multi-slope, single-span and multi-span, parallel folded plate and double folded plate, etc., which can meet the needs of different building planes. Commonly used cross-sectional shapes are V-shaped and trapezoidal.
 
2.SHELL ROOF STRUCTURE
The shell structure generally refers to a layered structure. Its force characteristic is that the external force acts on the surface of the structure, such as the helmet of the motorcyclist, the shell and so on. Commonly used in various industrial design fields. The shell structure is a space curved structure composed of a space curved plate or an edge member. The thickness of the shell is much smaller than other dimensions of the shell, so the shell structure has good spatial force transmission performance, and can form a load-bearing structure with high bearing capacity and high rigidity with a small component thickness, and can cover or maintain large-span The space does not need space pillars, and can have the dual functions of load-bearing structure and enclosure structure, thereby saving structural materials.
 
3.GRID ROOF STRUCTURE
A relatively common large-span roof structure is used. This kind of structure has strong integrity, good stability, large space rigidity and good shockproof performance. The height of the mesh frame is small, and it can be assembled into a large-span building by using smaller rod-shaped components, and the building space can be effectively used. The large-span grid structure suitable for industrial production can be divided into two types: flat grid and shell grid, which can adapt to various plane shapes such as circle, square and polygon. Flat-type grids are mostly double-layered, shell-shaped grids are divided into single-layer and double-layered, and there are single-curve, hyperbolic and other roof forms.
 
4.SUSPENSION ROOF STRUCTURE

Suspension cable structure is a load-bearing structure formed by flexible tension cables and their edge members, which are mainly used in construction engineering and bridge engineering. The material of the cable can be steel wire bundle, steel wire rope, steel hinge wire, chain, round steel, and other wires with good tensile properties.

Suspension cable structure can make full use of the tensile properties of high-strength materials, and can achieve large span, small self-weight, material saving, and easy construction.

 
5.INFLATABLE ROOF          STRUCTURE

Membrane structure is an important branch of light space structure. In addition to its colorful shapes, it also has excellent architectural characteristics, structural characteristics, and suitable economical type. Therefore, the birth of membrane structure has rapidly developed all over the world. The membrane structure building is mainly divided into tension membrane structure, skeleton membrane structure, inflatable membrane structure, cable truss membrane structure, tensioned whole and cable dome membrane structure.
