It is necessary to ensure the stability of the steel beam structure and the symmetry of the force on the central column to avoid the phenomenon that the central column tilts or falls even though the connection strength between the two is sufficient. Therefore, it is necessary to provide a stable and symmetrical steel structure node component. Utility Model Content

[0039] Please refer to Figure 1 - Figure 2 An embodiment of the utility model provides a steel structure node component 100, including: a center column 10, a steel beam 20 and a connecting member 30.

[0040] Among them, the steel beam 20 is located at the top 11 of the middle column 10, and at least includes a support portion 21 that fits with the top 11 of the middle column 10. Observed along the first direction F2 perpendicular to the axis F1 of the middle column 10, the central symmetry line F3 of the support portion 21 coincides with the axis F1 of the middle column 10. The connecting member 30 penetrates into the top 11 of the middle column 10 along the axial direction of the middle column 10 from the side of the steel beam 20 away from the middle column 10, and the two connecting members 30 are symmetrically distributed about the central symmetry line F3 of the support portion 21. Observed along the first direction F2, the distance from the center of any connecting member 30 to the central symmetry line F3 is denoted as a, and the distance from the center of the connecting member 30 to the periphery 14 of the middle column 10 is denoted as b, which satisfies the relationship: 0.84b>a>0.71b.

[0041] Among them, the support part 21 of the steel beam 20 fits with the top 11 of the middle column 10, ensuring that when observed in the direction perpendicular to the axis F1 of the middle column 10, the central symmetry line F3 of the support part 21 coincides with the axis F1 of the middle column 10. This helps to maintain the symmetry of the structure and improve stability. The connector 30 penetrates the top 11 of the middle column 10 along the axis of the middle column 10, and forms a symmetrical distribution with the central symmetry line F3 of the support part 21. This symmetrical layout can evenly transfer the load to the middle column 10, avoiding uneven force causing deflection or instability of the structure. The numerical range in the relationship: 0.84b>a>0.71b is determined by calculation and analysis of structural mechanics and material mechanics. The goal of these relationships is to ensure that the position and layout of the connector 30 enables the structure to remain stable when subjected to external forces and prevent excessive bending or torsion.

[0042] More preferably, the relationship is satisfied: 0.81b>a>0.74b.

[0043] The above relationship increases the lower limit (0.74b), which can ensure that the connection member 30 is not too close to the periphery 14 of the center column 10, prevent edge effects, and make the structure more stable. At the same time, the upper limit (0.81b) is reduced, which helps to ensure that the position of the connection member 30 is not too far away from the periphery 14 of the center column 10, avoid unnecessary load transfer paths of the structure being too long, and reduce deformation of the structure.

[0044] More preferably, the relationship is satisfied: a=0.77b.

[0045] By limiting a=0.77, the design finds a balance between the stability and deformation of the structure. This setting takes into account both the factors of preventing excessive deformation of the structure and ensuring that the structure is sufficiently stable. This setting is determined based on an in-depth study of the properties of the materials used and the limitations of actual engineering.

[0046] More preferably, the steel beam 20 further includes an extension portion 22 .

[0047] The extension portion 22 is integrally formed with the support portion 21 and is separated from the top portion 11 of the center column 10. When viewed along the first direction F2, the two extension portions 22 are formed at the left and right ends of the support portion 21 and are symmetrically distributed with respect to the central symmetry line F3 of the support portion 21. The two connecting members 30 are located between the two extension portions 22, and the axial projection of the extension portion 22 partially overlaps with the top portion 11 of the center column 10.

[0048] Among them, by forming two extensions 22 at the left and right ends of the support part 21 and forming a symmetrical distribution with the central symmetry line F3 of the support part 21, the symmetry of the structure is achieved. Symmetry usually helps to balance the force of the structure and reduce the deformation and stress concentration caused by uneven loading. The connection member 30 is located between the two extensions 22, which can improve the stability of the overall structure. The connection member 30 provides additional support on the left and right sides of the extension 22, which helps to disperse the load and reduce the deformation of the structure. The projection of the extension 22 in the axial direction overlaps with the top 11 of the center column 10. Such a design can ensure that the joint point of the support part 21 and the extension 22 in the vertical direction is located at the top 11 of the center column 10, which helps to evenly transfer the load to the center column 10 and improve the stability of the structure. The extension 22 is integrally formed with the support part 21 and separated from the top 11 of the center column 10, which helps to simplify the manufacturing and assembly process. Such a design can reduce the number of connecting parts and improve the manufacturability and maintainability of the structure. Adding extensions 22 on both sides of the structure can increase the overall strength of the structure. This helps to reduce stress concentration when the structure is subjected to external forces and improve the durability and bearing capacity of the structure.

[0049] More preferably, the steel beam 20 further includes: a supporting rib 23 .

[0050] The support rib 23 is integrally formed with the support portion 21 and is perpendicular to the support portion 21. When viewed along the first direction F2, the two support ribs 23 are formed at the left and right ends of the support portion 21 and are symmetrically distributed with respect to the central symmetry line F3 of the support portion 21. The two connecting members 30 are located between the two support ribs 23, and the extension portion 22 is located on the side of the support rib 23 away from the connecting member 30. The projection of the support rib 23 in the axial direction is completely located on the top 11 of the center column 10.

[0051] Among them, integrally forming the support rib 23 with the support portion 21 and perpendicular to the support portion 21 helps to increase the longitudinal stability of the structure. The vertical design of the support rib 23 can effectively prevent the deformation of the structure in the vertical direction and improve the performance of the structure when bearing vertical loads. By forming two support ribs 23 at the left and right ends of the support portion 21 and forming a symmetric distribution with respect to the central symmetry line F3 of the support portion 21, the symmetry of the structure is achieved. Symmetry helps to evenly disperse the load, reduce the uneven stress on the structure, and improve the stability of the structure. Placing the connecting member 30 between the two support ribs 23 helps to ensure the reasonable position of the connecting member 30 in the structure. Such a design can make the connecting member 30 located in the area of the support structure and improve the overall strength of the structure. The projection of the support rib 23 in the axial direction is completely located on the top 11 of the middle column 10, which helps to ensure that the support rib 23 fully supports the top 11 of the middle column 10. Such a design helps to improve the overall stability and strength of the structure. The design of the support rib 23 is coordinated with the position and function of the connecting member 30. The arrangement and shape of the support rib 23 help to support the connecting member 30, making the overall structure more coordinated when stressed.

[0052] More preferably, the included angle between the extension portion 22 and the support rib 23 is denoted as C, and satisfies the relationship: 75° < C < 85°.

[0053] Among them, selecting the included angle within the range of 75° < C < 85° helps to improve the stability of the structure. A larger included angle results in the intersection point between the support portion 21 and the extension portion 22 being closer to the connection point, which helps to disperse the load and improve the overall strength of the structure. In the selection of the included angle C, the feasibility in terms of the construction and manufacturing of the structure will be considered. A suitable included angle can simplify the manufacturing process and is easier to handle in actual construction. Selecting an appropriate included angle can help to reduce the stress concentration in the structure. An overly small or large included angle results in stress concentration at the connection point, while the range of 75° < C < 85° helps to evenly distribute the stress. Adjusting the included angle is to optimize the performance of the structure, such as reducing deformation, increasing the load-bearing capacity, etc. This can be achieved by selecting appropriate design parameters within a specific included angle range.

[0054] More preferably, it satisfies the relationship: 78° < C < 82°.

[0055] More preferably, it satisfies the relationship: C = 80°.

[0056] More preferably, the connecting member 30 includes: a stud 31 and a first nut 32.

[0057] Among them, the stud 31 axially penetrates the support portion 21 and penetrates into the middle column 10. The first nut 32 is located on the side of the support portion 21背离 the middle column 10 and is screwed tightly with the stud 31.

[0058] Among them, the stud 31 penetrates the support part 21 and penetrates the center column 10 axially to form a rigid connection structure. This arrangement helps to improve the robustness of the connection and ensure a firm connection between the support part 21 and the center column 10. By using the stud 31 to penetrate the support part 21 and the center column 10, the design is easier to manufacture and assemble. This connection method is usually easier to implement than other complex connection methods, thereby reducing the cost of manufacturing and assembly. The combination of the stud 31 and the first nut 32 provides a reliable connection method. Such a design can usually maintain a firm connection under stress and vibration environments to ensure the long-term stability of the structure. The connection method using the stud 31 and the first nut 32 is convenient for maintenance and repair. Threaded connection is usually a detachable connection method, so that the structure can be easily disassembled and reassembled when necessary. By tightening or loosening the first nut 32, the tightness of the connection can be adjusted, allowing fine-tuning or calibration after installation. This is beneficial for ensuring that the structure is in the correct position and state.

[0059] Preferably, the top 11 of the center column 10 is axially recessed to form a screw hole 12 and a nut slot 13 connected to the screw hole 12, and the connecting member 30 further includes: a second nut 33. The second nut 33 is fixed in the nut slot 13, and the stud 31 extends into the screw hole 12 and is tightened in cooperation with the second nut 33 in the nut slot 13.

[0060] Among them, the screw hole 12 and the nut slot 13 provide a precise and stable position, so that the stud 31 can be accurately positioned and fixed to the top 11 of the center column 10. By adopting this arrangement, the stability of the connection can be enhanced, and unnecessary displacement or loosening of the structure when subjected to force can be avoided. The design of the screw hole 12 and the nut slot 13 can make the positioning of the connection more accurate. The second nut 33 is fixed in the nut slot 13 to ensure that the relative position of the connection is not easy to change, thereby improving the accuracy and stability of the structure. The presence of the second nut 33 allows the tightness of the stud 31 to be adjusted by tightening or loosening. This is helpful for scenarios where different connection tightness is required in different situations, and also makes the structure more flexible and adjustable in use. Such a design allows the connector 30 to be easily installed and removed when needed. The presence of the second nut 33 allows the stud 31 to be easily inserted or pulled out of the screw hole 12, thereby realizing the rapid assembly and disassembly of the connector 30. The design of the screw hole 12, the nut slot 13 and the second nut 33 makes the structure easier to maintain. If the connecting member 30 needs to be repaired or replaced, it can be easily disassembled and reinstalled, thereby improving the maintainability of the structure.

[0061] In this way, by fitting the support portion 21 of the steel beam 20 with the top 11 of the center column 10, it is ensured that when observed in the direction perpendicular to the axis F1 of the center column 10, the central symmetry line F3 of the support portion 21 coincides with the axis F1 of the center column 10. This helps to maintain the symmetry of the structure and improve stability. The connector 30 penetrates the top 11 of the center column 10 axially along the center column 10 and forms a symmetrical distribution with the central symmetry line F3 of the support portion 21. This symmetrical layout can evenly transfer the load to the center column 10, avoiding uneven force causing deflection or instability of the structure. The relationship 0.84b>a>0.71b is determined through calculations and analysis of structural mechanics and material mechanics, ensuring that the position and layout of the connector 30 enable the structure to remain stable when subjected to external forces, preventing excessive bending or torsion.

[0062] The above-mentioned embodiments only express several embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present utility model patent shall be based on the attached claims.
