Description

Technical Field

[0001] The utility model relates to the technical field of rigid connection in steel structures, in particular to a rigid connection node structure between a steel beam and a steel column. Background Art

[0002] In steel structures, the connection between steel columns and steel beams is crucial, directly impacting the overall structural stability and safety of the building. Steel columns, as vertical support members, carry the crucial task of transferring loads to the foundation. Steel columns come in a variety of shapes, including H-shaped, box-shaped, and cylindrical. Regardless of the structure, the connection between steel columns and beams currently relies primarily on vertical welding and / or bolting.

[0003] However, in special-shaped steel structure buildings, due to the complexity and uniqueness of the design, inclined steel column structures or curved steel beam structures are often required. In this case, traditional connection methods face new challenges. This is mainly because when the inclined steel column and the curved steel beam are rigidly connected, the end of the steel beam cannot fully contact the side wall of the steel column, thereby affecting the strength and stability of the connection. In order to solve the above technical problems, the present application provides a special steel beam and steel column rigid connection node structure for special-shaped steel structure buildings. Utility Model Content

[0004] The utility model provides a rigid connection node structure between steel beams and steel columns, which can solve the technical problem of difficult connection between steel columns and steel beams in special-shaped steel structure buildings.

[0005] This application provides the following technical solutions:

[0006] A rigid connection node structure between a steel beam and a steel column, wherein the steel column is box-shaped, the steel beam is H-shaped, the steel column is arranged at an angle, and a node structure is arranged on the steel column. The node structure includes a special-shaped plate arranged on the top of the steel column and multiple groups of connection components arranged on the same side wall or different side walls of the steel column. The connection component includes a bottom plate and a vertical plate arranged perpendicular to the bottom plate, the bottom plate is used to connect to the lower flange of the steel beam, and the vertical plate is used to connect to the web of the steel beam; the side of the special-shaped plate corresponding to the connection component extends outward to form a top plate of the connection component, the top plate is used to connect to the upper flange of the steel beam, and the two side edges of the top plate gradually shrink in the direction away from the steel column to make it match the corresponding connected steel beam.

[0007] Beneficial effects:

[0008] 1. By setting special-shaped plates on steel columns and extending the top plates of the connection components according to the number and direction of the set connection components, multiple groups of connection components are formed into a whole, which is beneficial to improving the strength and stability of the overall connection; in addition, by setting special-shaped plates and connection components as intermediate connection structures, the length and position of the node structure can be set according to the special-shaped steel structure, so that it is completely connected to the steel beam without changing the structure of the steel beam, which is beneficial to be applicable to different special-shaped steel structures.

[0009] 2. By gradually narrowing the two side edges of the top plate away from the steel column to adapt to the corresponding connected steel beams, the width of the side of the special-shaped plate close to the steel column can be consistent with that of the steel column, and the width of the side close to the steel beam can be adapted to the steel beam. On the one hand, it is beneficial to disperse the load and reduce stress concentration; on the other hand, it is beneficial to the smooth transition between steel beams and steel columns of different sizes, thereby improving the stability of the overall structure.

[0010] 3. The node structure is pre-installed on the steel column before use, which can simplify the on-site construction process, reduce the time for on-site adjustment, facilitate rapid docking and installation, and help reduce the difficulty of on-site adjustment in special-shaped steel structure buildings.

[0011] Furthermore, when the height of the connecting assembly is consistent with the height of the steel beam, the base plate is horizontally arranged so that the free end of the base plate is aligned with the lower flange of the steel beam; when the height of the connecting assembly is greater than the height of the steel beam, the base plate is tilted upward relative to the horizontal plane so that the free end of the base plate contacts the lower flange of the steel beam.

[0012] Beneficial effects: The width of the connection component can be adjusted through the base plate to adapt to steel beams of different sizes, which is conducive to achieving a more stable connection. During on-site hoisting, the corresponding size of steel beam can be quickly selected according to the width of the connection component, thereby achieving a rigid connection between the steel beam and the steel column and improving installation efficiency.

[0013] Furthermore, when multiple groups of connection components are arranged on the same side wall of the steel column, a reinforcing block is provided in the triangular area formed by the adjacent vertical plates and the bottom of the special-shaped plates.

[0014] Beneficial effect: The provision of reinforcement blocks is beneficial to increasing the strength between adjacent vertical plates, thereby improving the overall connection strength.

[0015] Furthermore, the special-shaped plate is welded to the top of the steel column, and the edges of the special-shaped plate extend beyond the four sides of the steel column.

[0016] Furthermore, the thickness of the bottom plate is greater than the thickness of the lower flange of the steel beam, and the bottom plate is welded to the end of the lower flange of the steel beam.

[0017] Beneficial effect: It is beneficial to further improve the stability and connection strength of the connection components.

[0018] Furthermore, the vertical plate is connected to the web of the steel beam through a connecting plate and bolts.

[0019] Furthermore, the welding positions between the bottom plate and the lower flange of the steel beam and the welding positions between the top plate and the upper flange of the steel beam are both provided with connecting plates, and the upper flange end and the lower flange end of the steel beam are provided with connecting slopes, and the connecting slopes and the connecting plates constitute the welding area.

[0020] Beneficial effect: Setting the welding area is conducive to extending the welding gun for comprehensive welding, and at the same time it can provide a landing point for the solder and enhance the welding strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figure 2As shown, the node structure is used to connect the steel beam 2 and the steel column 1, and is set on the inclined steel column 1. The node structure includes a special-shaped plate 3 set on the top of the steel column 1 and multiple groups of connection components 4 set on the same side wall or different side walls of the steel column 1. Specifically, the special-shaped plate 3 is welded to the top of the steel column 1, and the edges of the special-shaped plate 3 exceed the four sides of the steel column 1. This embodiment is described in detail by taking the multiple groups of connection components 4 set on the same side wall of the steel column 1 as an example; specifically, Figure 3 As shown, three groups of connection components 4 are provided from left to right. Each connection component 4 includes a bottom plate 41 and a vertical plate 42 vertically welded to the bottom plate 41. The bottom plate 41 is used to connect with the lower flange 21 of the steel beam 2, and the vertical plate 42 is used to connect with the web 22 of the steel beam 2. Figure 2 As shown, one side of the special-shaped plate 3 corresponding to the connecting component 4 extends outward to form a top plate 31 of the connecting component 4. The top plate 31 is used to connect with the upper flange 23 of the steel beam 2, and the two side edges of the top plate 31 gradually shrink in the direction away from the steel column 1 so that it matches the corresponding connected steel beam 2.

[0030] When the height of the connecting assembly 4 is consistent with the height of the steel beam 2, the bottom plate 41 is set horizontally so that the free end of the bottom plate 41 is aligned with the lower flange 21 of the steel beam 2; when the height of the connecting assembly 4 is greater than the height of the steel beam 2, the bottom plate 41 is set upwardly with respect to the horizontal plane so that the free end of the bottom plate 41 is in contact with the lower flange 21 of the steel beam 2. Figure 3 As shown, in this embodiment, the bottom plates 41 of the first and third groups of connecting components 4 are tilted upward, the bottom plates 41 of the second group of connecting components 4 are horizontally arranged, and one side of the bottom plates 41 of the first and third groups of connecting components 4 is welded to the bottom plates 41 of the second group of connecting components 4, and one side of the vertical plates 42 of the first and third groups of connecting components 4 are welded to the left and right sides of the vertical plates 42 of the second group, so that the three groups of connecting components 4 become a whole; and in order to further improve the connection strength, in this embodiment, a reinforcing block 5 is also provided in the triangular area formed by the adjacent vertical plates 42 and the bottom of the special-shaped plate 3.

[0031] When the steel column 1 is connected to the steel beam 2, the vertical plate 42 is connected to the web 22 of the steel beam 2 through the connecting plate 61 and the bolts 62. When in use, two or four rows of bolts 62 can be set on the connecting plate 61 according to the connection strength. The number of bolts 62 in each row can be set to 6-10 according to the height of the steel beam 2. Figure 4 As shown, the bottom plate 41 is welded to the end of the lower flange 21 of the steel beam 2, and the top plate 31 is welded to the end of the upper flange 23 of the steel beam 2. In this embodiment, the thickness of the bottom plate 41 is greater than the thickness of the lower flange 21 of the steel beam 2, which is beneficial to improving the supporting strength of the connection component 4, and the thickness of the top plate 31 is consistent with the thickness of the upper flange 23 of the steel beam 2, which is beneficial to ensure that the top is flush. Figure 4As shown, the welding position between the bottom plate 41 and the lower flange 21 of the steel beam 2 and the welding position between the top plate 31 and the upper flange 23 of the steel beam 2 are both provided with a connecting plate 63, and the end of the upper flange 23 and the end of the lower flange 21 of the steel beam 2 are provided with a connecting slope 211, and the connecting slope 211 and the connecting plate 63 constitute a welding area; setting up the welding area is conducive to the insertion of the welding gun for comprehensive welding, and at the same time can provide a landing point for the solder, thereby enhancing the welding strength.
