[0002] Cast steel joints are key components used for steel structure connections, typically made of cast steel, and are widely used in construction, bridges, and other engineering fields. However, existing cast steel joints have at least the following drawbacks: 1.

Existing cast steel joints are cumbersome to install and dismantle, making it difficult to connect multiple large-span steel beams. Therefore, we introduce a new cast steel joint with a positioning structure. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please refer to Figures 1-5. This utility model provides a technical solution:

[0026] A cast steel node with a positioning structure includes a connecting component 1 and two square tubes 12. The lower end of the connecting component 1 is fixedly connected to four support components 2 in a ring array.

[0027] In this embodiment, the connecting component 1 includes a fixing tube 11. Two positioning tubes 14 are fixedly connected to the rear part of the outer surface of the fixing tube 11. Two connecting frames 13 are fixedly connected to the left and right parts of the outer surface of the fixing tube 11. Three connecting frames 13 are fixedly connected to the lower part of the front part of the outer surface of the fixing tube 11. The lower ends of the two square tubes 12, the lower parts of the outer surfaces of the positioning tubes 14, and the lower parts of the outer surfaces of the connecting frames 13 are fixedly connected to the upper ends of the four supporting components 2 respectively.

[0028] The above scheme facilitates the connection process of the entire cast steel node through the connecting component 1, and the fastening connection process of the V-shaped column to the roof truss and the rhomboid grid to the roof through the two sets of longitudinal square tubes 12, two positioning tubes 14 and three connecting frames 13, thereby improving flexibility.

[0029] In this embodiment, the support component 2 includes a support tube 21. Several connectors 22 are longitudinally fixedly connected to both the front and rear parts of the outer surface of the support tube 21. Connecting tubes 23 are sleeved on the outer surfaces of both sets of longitudinal connectors 22. Positioning screws 24 are inserted through the right ends of the connecting tubes 23. The support tube 21 is fixedly connected to the connecting component 1. The connecting tube 23 includes a tube body 231. A first limiting ring 232 is fixedly sleeved on the outer surface of the tube body 231. A fixing sleeve 233 is sleeved on the right side of the outer surface of the tube body 231. A second limiting ring 234 is fixedly sleeved on the right side of the outer surface of the fixing sleeve 233. The tube body 231 is sleeved with the connectors 22. Several positioning screws 24 pass through several connecting tubes 23 and are inserted through the connectors 22. Several sets of transverse positioning screws 24 are not on the same plane.

[0030] The above scheme involves supporting several connecting pipes 23 with several connectors 22, fixing the connecting pipes 23 to the connectors 22 with several positioning screws 24 to improve stability, fitting the fixing sleeve 233 to the pipe body 231 and fixing it with screws to position the fixing sleeve 233, facilitating the connection of multiple steel beams with several connecting pipes 23, and facilitating the connection of the entire connecting pipe 23 to the external steel beam with the right side of the outer surface of the fixing sleeve 233 and the second limiting ring 234.

[0031] It should be noted that this utility model is a cast steel node with a positioning structure. In large building structures, the connections between V-shaped columns and roof trusses, and between rhomboid grids and the roof, are extremely complex. These locations have numerous members and multiple acute angles, resulting in large bending moments and easily exceeding stress limits in the node area. The two positioning tubes 14, four square tubes 12, and three connecting frames 13 on the connecting component 1 are designed specifically for such complex situations. Through a reasonable layout and unique structure, they provide a connection foundation for members in different directions and at different angles, effectively dispersing stress and ensuring the node... Maintaining stability even under complex stress conditions, meeting high-strength connection requirements, and successfully completing the connection process for complex parts, the installation and fixation of the four support components 2 further enhance the stability of the entire cast steel node. They are firmly connected to the lower ends of the two lower square tubes 12, the lower outer surface of the middle connecting frame 13, and the lower outer surface of the lower positioning tube 14, respectively. This fixing method allows the support components 2 to provide support to the connecting components 1 from multiple positions, acting like solid pillars to firmly stabilize the cast steel node within the building structure, effectively distributing the load borne by the node and preventing displacement of the node under stress. The displacement or deformation ensures the stability of the entire structure. Several tubes 231 are interlocked with the connector 22. This connection method provides the basis for the installation of the connecting tube 23. Several positioning screws 24 are used to fix the connection between the fixing sleeve 233 and the connector 22. The tightening action of the screws makes the connecting tube 23 tightly connected to the connecting assembly 1, ensuring the stability of the connection. Furthermore, this installation method makes the disassembly process of several connecting tubes 23 simple and convenient when maintenance, replacement or adjustment is required. Simply unscrew the positioning screws 24 to remove the connecting tube 23 from the connector 22, which greatly improves the performance of cast steel. The ease of later maintenance of the node is facilitated by the second limiting ring 234 set on several connecting pipes 23, which plays an important role in connecting the external steel beam. When the external steel beam is connected to the connecting pipe 23, the second limiting ring 234 can position and limit the steel beam. The steel beam can be accurately installed along the position of the second limiting ring 234, avoiding deviations during installation. At the same time, the second limiting ring 234 can also increase the contact area of ​​the connection, making the connection between the steel beam and the connecting pipe 23 tighter, thereby improving the stability of the connection and ensuring a reliable connection between the external steel beam and the cast steel node, so as to jointly bear the various loads applied by the building structure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
