Description

Technical Field

[0001] This utility model relates to the field of large-span building steel structure connection, specifically a connection node between a planar steel truss and a circular steel pipe column. Background Technology

[0002] Large-span stadium buildings typically use planar steel trusses and circular steel pipe columns as horizontal and vertical load-bearing components for the floor and roof. The connection method between the large-span planar steel trusses and circular steel pipe columns is crucial for reducing the column cross-sectional size, and also affects the structure's lateral resistance, component fabrication and installation, and project cost.

[0003] Existing planar steel trusses are usually connected to steel columns by direct rigid joints. However, rigid joints can cause large bending moments in the steel columns, requiring larger column cross-sections to resist these moments. Larger column cross-sections not only affect the building's functionality but also increase economic costs. Utility Model Content

[0016] The connection node between the planar steel truss and the circular steel pipe column as described above: the stiffener includes at least two intersecting third stiffening ribs, which are fixedly connected to the circular cover plate and the steel pipe column respectively.

[0017] As described above, the connection node between the planar steel truss and the circular steel pipe column is as follows: the third stiffening rib is arranged in a U-shaped structure, including a straight section and a vertical section.

[0026] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0027] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0028] Please see Figures 1-5 In this embodiment of the utility model, a connection node between a planar steel truss and a circular steel pipe column includes a steel plate 5, a circular cover plate 6, and a pot-type seismic hinge support 2.

[0029] The details are as follows;

[0030] Please see Figure 1 , Figure 2 The steel plate 5 is connected to the lower chord 1 of the planar steel truss by a reinforcing member;

[0031] The circular cover plate 6 is connected to the end of the steel pipe column 8;

[0032] The pot-type seismic hinge support 2 is disposed between the steel plate 5 and the circular cover plate 6, and both ends of the pot-type seismic hinge support 2 are fixed to the steel plate 5 and the circular cover plate 6 respectively. Preferably, the steel plate 5 and the circular cover plate 6 can be connected to the pot-type seismic hinge support 2 by welding or threading.

[0033] In detail, the connection node between the planar steel truss and the circular steel pipe column described in this utility model, in this embodiment, the lower chord 1 adopts a planar steel structure. Before the lower chord 1 is connected to the steel pipe column 8, the lower chord 1 and the circular cover plate 6 are respectively fixedly connected to the reinforcing member. The hinged connection between the lower chord 1 and the steel pipe column 8 can be well achieved by fixing the pot-type seismic hinge support 2 to the circular cover plate 6 and the steel plate 5 respectively. This node form avoids the rigid connection between the lower chord 1 and the steel pipe column 8, greatly reduces the bending moment generated on the steel pipe column 8, and can effectively reduce the cross-sectional size of the steel pipe column 8, and has good seismic performance.

[0034] The aforementioned pot-type seismic hinge support 2 can adopt existing structures, which will not be elaborated further in this embodiment. The pot-type seismic hinge support 2 can realize the hinge connection between the lower chord 1 and the steel pipe column 8, release the internal stress of the lower chord 1 and the main body of the steel pipe column 8, and play a role in seismic resistance and damping at the node it acts on.

[0035] Specifically, the reinforcing member includes a second stiffening rib 4 connecting the lower chord 1 and the steel plate 5. Multiple first stiffening ribs 3 are respectively provided on both sides of the second stiffening rib 4, and the first stiffening ribs 3 are fixed to the lower chord 1 and the steel plate 5. The first stiffening ribs 3 and the second stiffening ribs 4 can transfer the internal stress generated by the lower chord 1 to the pot-type seismic hinge support 2 and the lower steel pipe column 8, which greatly reduces the bending moment generated on the steel pipe column 8, and at the same time can effectively reduce the cross-sectional size of the steel pipe column 8.

[0036] In one exemplary embodiment, the first stiffening rib 3 and the second stiffening rib 4 are perpendicular to each other.

[0037] Preferably, the second stiffening rib 4 is arranged in a rectangular structure, so that the connection area of ​​the second stiffening rib 4 with the lower chord 1 and the steel pipe column 8 is the same, so that the lower chord 1 and the steel pipe column 8 support the second stiffening rib 4 with the same area, thus providing stability.

[0038] Preferably, the first stiffening rib 3 is arranged in an isosceles trapezoidal structure, which can better realize the connection between the pot-type seismic hinge support 2 and the lower chord 1.

[0039] Preferably, the plurality of first stiffening ribs 3 are equidistantly distributed along the side ends of the second stiffening ribs 4, so that the force on the lower chord 1 and the steel pipe column 8 is balanced, thereby improving the stability of the connection between the lower chord 1 and the steel pipe column 8. Alternatively, in another embodiment, the first stiffening ribs 3 are arranged in a figure-eight shape along the side of the second stiffening ribs 4.

[0040] Preferably, a reinforcing rib is provided between the circular cover plate 6 and the steel pipe column 8. Its main function is to enhance the structural stability between the circular cover plate 6 and the steel pipe column 8 and to ensure that the circular cover plate 6 does not undergo large vertical deformation.

[0041] Preferably, the reinforcing rib includes at least two intersecting third stiffening ribs 7, which are fixedly connected to the circular cover plate 6 and the steel pipe column 8 respectively. This increases the strength and rigidity of the steel pipe column 8 without increasing the outer wall thickness of the steel pipe column 8, and prevents the circular cover plate 6 from warping and deforming.

[0042] Please see Figure 1 , Figure 3The third stiffening rib 7 is arranged in a U-shaped structure, including a straight section and a vertical section. The straight section of the third stiffening rib 7 is arranged between the circular cover plate 6 and the steel pipe column 8, and is fixed to the circular cover plate 6 and the steel pipe column 8. The vertical section of the third stiffening rib 7 is parallel to the axial direction of the steel pipe column 8 and is located on the outside of the steel pipe column 8.

[0043] Furthermore, the third stiffening rib 7 inside the steel pipe column 8 can transfer the concentrated force from the lower chord 1 to the steel pipe column 8. The third stiffening rib 7 can overcome the force caused by uneven concentrated force and ensure that the circular cover plate 6 does not undergo large vertical deformation. The internal force of the lower chord 1 is transferred to the pot-type seismic hinge support 2 and the lower steel pipe column 8 through the first stiffening rib 3 and the second stiffening rib 4, which greatly reduces the bending moment generated on the steel pipe column 8 and can effectively reduce the cross-sectional size of the steel pipe column 8.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
