Description

Technical Field

[0001] This utility model belongs to the field of steel structure, specifically relating to a connection node between a circular tube column and a multi-directional steel beam. Background Technology

[0002] Circular tubular columns have characteristics such as "isotropic cross-section (uniform stress), high torsional stiffness, and small space ratio", and are widely used in large-span and complex-shaped projects. However, when there are multi-directional steel beam intersections in a circular tubular column, it can easily affect the structural strength. If it is not effectively reinforced, it will cause safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide a connection node between a circular tube column and a multi-directional steel beam, which can effectively reinforce the intersection of the multi-directional steel beams.

[0004] The technical solution adopted in this utility model is:

[0005] A connection node between a circular tube column and a multi-directional steel beam is disclosed. The circular tube column has several H-beam ends distributed circumferentially. One end of each H-beam end is welded to the circular tube column, and the other end has a beam positioning plate for positioning when connecting adjacent H-beam segments and a beam connecting plate for connection. An upper reinforcing plate is attached to the upper flange, and a lower reinforcing plate is attached to the lower flange. Stiffening ribs are provided on both sides of the web. One side of the upper reinforcing plate is welded to the circular tube column, and the remaining side is welded to the upper flange of the H-beam end. One side of the lower reinforcing plate is welded to the circular tube column, and the remaining sides are all welded to the lower flange of the H-beam end. The upper and lower edges of the stiffening ribs are welded to the upper and lower flanges of the H-beam end, respectively, and one side is welded to the web of the H-beam end.

[0006] Preferably, a central reinforcing plate is provided inside the end of the H-beam. The central reinforcing plate is inserted into the stiffening rib through a slot. One side of the central reinforcing plate is welded to the circular tube column, and the central reinforcing plate is welded to the stiffening rib and the web of the end of the H-beam.

[0007] Preferably, the circular tube column is arranged in sections, and each section of the circular tube column is welded with a column positioning plate for positioning when the sections of the circular tube column are connected.

[0008] Preferably, the beam positioning plate is located on the upper flange plate at the end of the H-beam and is partially cantilevered.

[0009] Preferably, the beam connecting plate is located on both sides of the web at the end of the H-beam and is partially cantilevered. The beam connecting plate is provided with bolt holes for accommodating high-strength bolts.

[0010] Preferably, the thickness of the beam connecting plate is the same as the thickness of the web plate at the end of the H-beam.

[0011] Preferably, the ends of the H-beams are staggered in height.

[0012] Preferably, studs are welded to both the upper flange plate and the upper reinforcing plate, as well as the lower flange plate and the lower reinforcing plate.

[0013] Preferably, the circular tube column is a steel-concrete composite column or a pure steel circular tube.

[0014] The beneficial effects of this utility model are:

[0015] The upper reinforcing plate can improve the bending stiffness of the upper flange plate, and the lower reinforcing plate can improve the bending stiffness of the lower flange plate. The stiffening ribs can enhance the lateral stiffness and integrity of the joint area, and can effectively reinforce the multi-directional steel beam intersection joint. It is suitable for steel structure buildings with large spans and multi-directional steel beam intersections, such as stadiums, super high-rise buildings, and convention centers. The H-beam ends can be prefabricated in the factory and spliced ​​on site. Due to the segmented splicing, the end size and weight are small, so they can be accurately positioned on the corresponding design position on the circular tube column. At the same time, the beam positioning plate can ensure the docking accuracy between the H-beam end and the adjacent H-beam segment, which can not only control the installation deviation, but also significantly shorten the on-site positioning time.

[0019] The present application will be further described below with reference to the accompanying drawings and embodiments.

[0020] This embodiment discloses a connection node between a circular tube column and a multi-directional steel beam, such as... Figure 1 and Figure 2As shown: Several H-beam ends 2 are distributed circumferentially along the cylindrical column 1; one end of each H-beam end 2 is welded to the cylindrical column 1; the other end of each H-beam end 2 is provided with a beam positioning plate 3 and a beam connecting plate 6. The beam positioning plate 3 is used for positioning when connecting adjacent H-beam segments, and the beam connecting plate 6 is used for connecting adjacent H-beam segments; an upper reinforcing plate 7 is attached to the upper flange of each H-beam end 2, and one side of the upper reinforcing plate 7 is welded to the cylindrical column 1. The remaining edges are welded to the upper flange plate of the H-beam end 2; a lower reinforcing plate 8 is attached to the lower flange plate of the H-beam end 2, one side of the lower reinforcing plate 8 is welded to the circular tube column 1, and the remaining edges are all welded to the lower flange plate of the H-beam end 2; stiffening ribs 5 are provided on both sides of the web of the H-beam end 2, the upper and lower edges of the stiffening ribs 5 are welded to the upper flange plate and the lower flange plate of the H-beam end 2 respectively, and one side is welded to the web of the H-beam end 2.

[0021] The upper reinforcing plate 7 can improve the bending stiffness of the upper flange plate, and the lower reinforcing plate 8 can improve the bending stiffness of the lower flange plate. The stiffening rib 5 can enhance the lateral stiffness and integrity of the joint area, and can effectively reinforce the multi-directional steel beam intersection joint. It is suitable for steel structure buildings with large spans and multi-directional steel beam intersections, such as stadiums, super high-rise buildings, and convention centers. The H-beam end 2 can be prefabricated in the factory and spliced ​​on site. Due to the segmented splicing, the end size and weight are small, so it can be accurately positioned on the corresponding design position on the circular tube column 1. At the same time, the beam positioning plate 3 can ensure the docking accuracy between the H-beam end 2 and the adjacent H-beam segment, which can not only control the installation deviation, but also significantly shorten the on-site positioning time.

[0022] like Figure 1 and Figure 2 As shown, in this embodiment, preferably, the beam positioning plate 3 is set on the upper flange plate of the end 2 of the H-shaped steel beam and is partially cantilevered. The beam positioning plate 3 can determine the docking accuracy. After the splicing is completed, the beam positioning plate 3 can be cut off.

[0023] like Figure 1 and Figure 2 As shown, in this embodiment, preferably, the beam connecting plate 6 is located on both sides of the web of the H-beam end 2 and is partially cantilevered. The beam connecting plate 6 has bolt holes for high-strength bolts. The double shear plate and high-strength bolts work together to resist shear force, resulting in significantly better joint ductility and seismic performance than traditional welded joints. The shear-resistant high-strength bolts are grade 8.8 or 10.9, and their quantity is configured according to the shear bearing capacity requirements of the beam. Preferably, the thickness of the beam connecting plate 6 is the same as the thickness of the web of the H-beam end 2.

[0024] like Figure 1 and Figure 2As shown, in this embodiment, preferably, the upper flange plate and the upper reinforcing plate 7, and the lower flange plate and the lower reinforcing plate 8 are all welded with studs 9. The studs 9 can enhance the bond between the steel beam and the concrete and exert a combined effect.

[0025] like Figure 1 As shown, in this embodiment, preferably, a central reinforcing plate 4 is provided inside the end 2 of the H-shaped steel beam. The central reinforcing plate 4 is inserted into the stiffening rib 5 through a slot. One side of the central reinforcing plate 4 is welded to the circular tube column 1. The central reinforcing plate 4 is welded to the stiffening rib 5 and the web of the end 2 of the H-shaped steel beam. The central reinforcing plate 4 can disperse stress and prevent local buckling.

[0026] like Figure 1 As shown, in this embodiment, preferably, the circular tube column 1 is segmented, and each segment of the circular tube column 1 is welded with a column positioning plate 10 for positioning when the segments of the circular tube column are joined. The column positioning plate 10 can ensure the joining accuracy between the segments of the circular tube column. After the splicing is completed, the column positioning plate 10 can be cut off.

[0027] like Figure 1 As shown, in this embodiment, preferably, the ends 2 of the H-shaped steel beams are staggered in height. This facilitates installation and avoids stress concentration.

[0028] In this embodiment, the circular tube column 1 is a steel-concrete composite column or a pure steel circular tube.

[0029] In this embodiment, the materials of the column positioning plate 10, beam positioning plate 3, beam connecting plate 6, upper reinforcing plate 7, middle reinforcing plate 4, lower reinforcing plate 8, and stiffening rib 5 are the same as the base material (preferably Q355B) to reduce on-site welding errors.

[0030] In this embodiment, there are 5 H-beam ends 2, and the specific number can be set according to actual needs.

[0031] The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
