Overview
Principles of Construction
Cast steel node is a type of node casting made through casting technology in steel structures, which has high strength, high durability, and good adaptability.
Cast steel nodes play a crucial connecting role in steel structures, as they can firmly connect multiple structural components together and transmit forces in various directions. This type of node form is not limited by any spatial structural form, and has a large degree of design freedom, which can greatly restore the aesthetics of the building. Cast steel nodes can be cast into any shape in space, making any shape of building shape a reality. At the same time, using circular chamfers and smooth sections in the high stress areas of the nodes can make the stress distribution of the nodes more reasonable.
Cast steel nodes are commonly used in large sports venues, high-speed railway stations, airport terminals, theaters, exhibition halls, and other large-span complex steel structure buildings, playing an important role in the overall structural stability. In addition, the cast steel nodes are cast as a whole in the factory, which can avoid stress concentration caused by intersecting line cutting and overlapping weld welding, greatly improving the reliability and safety of the nodes.
However, the processing cycle of cast steel joints is relatively long and needs to be customized in advance before entering the construction site to avoid delaying the overall construction cycle. Meanwhile, cast steel joints are usually heavier than other materials and the construction difficulty is relatively high. However, despite this, cast steel joints still occupy an important position in the field of steel structures due to their unique advantages and wide application scenarios.
Product advantages
The product advantages of cast steel joints are mainly reflected in high overall stability, strong design flexibility, wide adaptability, high aesthetics, and convenient construction.
1. High overall stability: The cast steel nodes are poured and formed as a whole in the factory, avoiding stress concentration caused by intersecting line cutting and overlapping weld welding, making the steel structure more reasonable in stress distribution, and the overall structure more stable.
2. Strong design flexibility: Cast steel nodes have good adaptability and can be cast into nodes with complex shapes and cavities according to building needs. They have a large degree of design freedom and can meet the needs of various complex structures.
3. Wide applicability: The application of cast steel nodes is not limited by node position, shape, or size, and can be cast into any shape in space. It can be used for both central nodes and support nodes in structures, with a wide range of applications.
4. High aesthetic appeal: The overall shape of the cast steel joint is simple and beautiful, avoiding the overlapping of welds, with accurate dimensions and strong plasticity, which can fully express the architect's design ideas and aesthetic needs.
5. Convenient construction: The steel casting nodes are completed in the factory, greatly reducing the workload of high-altitude operations, lowering overall construction costs, improving overall project quality, and reducing the harm caused to construction personnel by high-altitude operations.

| The working principle of cast steel joints is mainly to cast high-temperature molten steel into a specially designed mold, cool and solidify it to form connecting components with high strength, durability and seismic resistance, which are used as key connecting parts in steel structures.
In complex spatial structures, due to the numerous branch pipes at nodes, conventional nodes may result in a large number of dense overlapping welds, affecting the quality of welding and the working performance of nodes. However, cast steel joints can overcome this defect by directly casting molten steel into the desired shape through casting processes, greatly reducing stress concentration caused by overlapping welding. This type of node can be cast into any shape in space, making any shape of building shape a reality. At the same time, cast steel material also has good shaping, toughness, and weldability, further enhancing the reliability and durability of the node.
In the casting process, the first step is to deepen the design of the cast steel nodes, using computer-aided design (CAD) technology to ensure that the nodes not only conform to the architect's design ideas, but also meet the requirements of structural design and casting production. Next, proceed with model making, select appropriate model making methods such as wooden models, wax models, metal models, etc., and customize according to the characteristics of the project. Then, the casting process is formulated, including the selection of coatings, the design of sprue and riser systems, etc., to ensure the quality of the castings. Finally, through heat treatment process, the internal structure of the steel is changed, the steel properties are improved, and the cast steel nodes achieve the required performance indicators. |
Product Structure | The product structure of cast steel nodes is mainly composed of cast steel parts cast as a whole, with complex geometric shapes and intersecting node designs.
Cast steel nodes play a core role in large-span truss structures, especially in the intersection of multiple members. It is made through integral casting process, which enables cast steel nodes to avoid stress concentration problems caused by intersecting line cutting and overlapping weld seam welding. The appearance of cast steel joints is diverse, which can meet the requirements of various complex structures, especially in dealing with complex intersection joints. Cast steel joints exhibit unique advantages.
In addition, the material selection of cast steel joints is also very important, usually requiring low sulfur and phosphorus content, high purity, and high low-temperature impact performance to ensure their high strength, good plasticity, toughness, and weldability. These characteristics enable cast steel joints to withstand large loads and maintain good welding performance under low-temperature conditions. |
Applications | Cast steel joints are mainly used in key parts of large-span spatial pipe truss steel structures and high-rise building structures.
In large-span space pipe truss steel structures, cast steel nodes are widely used to handle complex intersection nodes due to their unique properties such as high strength, good plasticity, toughness, and weldability. These structures are commonly found in large civil landmark buildings such as convention centers, sports stadiums, airports, etc. Cast steel joints can ensure that these structures can maintain stability and safety even under heavy loads.
In addition, cast steel joints also play an important role in high-rise building structures. Especially in critical areas with complex stress, such as the connection between the core cylinder and the truss, cast steel joints can provide reliable connections to ensure the safety of the overall structure. These high-rise buildings may include commercial buildings, office buildings, etc., among which the design and welding process of cast steel joints are particularly important. |
