What is the difference between steel structure and grid?
Steel structure and grid are two commonly used structural forms in modern architecture. Steel structures are widely used in industrial plants, high-rise buildings, bridges and other projects due to their high strength, light weight and fast construction speed. As a new type of spatial structure, the grid has also received more and more attention due to its good mechanical performance, high space utilization, and beautiful appearance. This article will focus on the differences between these two structures.
Structure type
Steel structure
Steel structure is a structural form made of steel connected by welding, rivets or bolts. Steel structures usually use H-shaped steel, I-shaped steel and other shaped steel as the main components, and are connected by welding or rivets to form spatial structures of various shapes. Steel structures are characterized by high strength, light weight, good seismic resistance, and good ductility.
Grid
The grid is a spatial structure formed by rods connected through nodes. The grid is usually composed of triangular, quadrilateral or hexagonal rods, which are connected through nodes to form various shapes of spatial structures. The characteristics of the grid are good stress performance, high space utilization, beautiful appearance, and can adapt to various complex terrains and architectural shapes.
Application scope
Steel structure
Steel structures are widely used in industrial plants, high-rise buildings, bridges and other projects. In industrial plants, steel structures can be used for load-bearing structures, roofs and walls; in high-rise buildings, steel structures can be used for load-bearing structures, roofs and walls; in bridges, steel structures can be used for load-bearing structures and walls. Bridge deck etc.
Grid
Grids are mainly used in large public buildings, convention and exhibition centers, sports venues and other projects. In these projects, grids can be used on roofs and walls to provide good space utilization and visual effects.
Construction method
Steel structure
The construction methods of steel structures mainly include welding and bolting. Welding is to connect steel materials into various shapes of spatial structures through the welding process; bolting is to connect steel materials into various shapes of spatial structures through bolts. The construction speed of steel structures is fast, but attention must be paid to welding quality and anti-corrosion treatment.
Grid
The construction methods of grid mainly include rod processing and node connection. Rod processing is to cut steel into rods of various shapes; node connection is to connect rods into various shapes of spatial structures through nodes. The construction of grids requires a high level of technology and precision, but it can adapt to various complex terrains and architectural shapes.
Summarize
Steel structure and grid are two different structural forms, with their own characteristics and application scope. When choosing which structural form to use, comprehensive considerations need to be made based on the specific needs and conditions of the project. At the same time, in order to ensure the quality and safety of the project, construction management and quality control need to be strengthened.
