Steel space frame structure is a relatively new form of building facility structure. In the production of Steel space frame structure, we must pay attention to the quality. Unqualified quality will be an important problem for subsequent construction, and will even cause many safety risks.
Welded hollow ball joints and bolted ball joints are the two most commonly used space frame joint forms in my country at present. These two joint forms are favored by the majority of engineers and technicians due to their respective advantages, especially the bolt ball joint. Due to the use of computer-aided design to draw the processing diagram, the angle of the bolt screw hole and the blanking length of the bar can be determined with high precision.
space frame processing has followed China's reform and opening up so far, and the improvement of technology has won a great development trend. The form of steel structure space frame engineering is more peculiar, and the design and professionalism are more skilled. So what are the advantages of space frame engineering projects ? , so that the indoor space structure is formed by connecting multiple components according to the nodes according to a certain space frame diagram method.
In the space frame structure, the nodes play the role of connecting the intersecting bars and transferring the roof load and crane load. The space frame structure belongs to the space rod system, and there are at least 6 rods intersecting on a node, and as many as 13 rods. This adds a certain difficulty to the node design. The number of nodes of the space frame is large, and the amount of steel used in the nodes accounts for 1/5~1/4 of the steel used in the whole space frame, and the reasonable design node to the safety of the space frame, production and installation, project progress, steel indicators and project cost has a direct relationship.
The space frame structure is a load-bearing roof structure with light weight, high spatial rigidity and good seismic performance, and belongs to the multi-time hyperstatically indeterminate spatial structure system.The installation and construction methods are generally divided into the overall installation method and the high-altitude bulk method.
The space frame structure is a high-order hyperstatically indeterminate structure, its node structure is simple, its component production is factory-processed with high precision, and its construction period is short. widely used in construction.
The steel structure canopy has a wide range of applications. It can be built between two buildings as a connecting channel between the two buildings, that is, the aisle canopy;
The steel structure tube truss technology has been popular abroad for many years. While the Chinese construction industry is experiencing rapid development, it is gradually paying attention to the building roof system. On this basis, steel structure tube truss technology has been deeply researched, developed, and applied. Next, we explore this design structure.
There are single-span, double-span, or multi-span single-slope and double-slope forms. The single-span rigid frame structure can be divided into the hingeless rigid frame, two-hinged rigid frame, and three-span rigid frame according to the arrangement of components and support constraints.
Since the arched roof structure of color plate was introduced in the United States in the early 1990s, it has been widely used in factories, exhibition halls, and warehouses. stadiums, hangars, markets, and other buildings, due to its advantages of high maneuverability, fast construction speed, low cost, long service life, practical and beautiful appearance, etc..
Fireproof coatings for space frame processing engineering have remarkable fireproof, heat insulation, heat preservation, water vapor, corrosion resistance, and other characteristics.
The transfer center of the civil airport is composed of the main building, finger gallery, aviation material warehouse, and rest area of the crew.
