Description

Technical Field

[0001] The utility model relates to the technical field of building components, in particular to a primary and secondary beam rigid connection node structure. Background Art

[0002] In steel structure construction, the connection between H-shaped steel primary and secondary beams is a critical connection point for ensuring structural safety. Currently, the most common rigid beam connection involves bolting the secondary beam's web to the primary beam's web or a stiffening plate attached to the primary beam's web, followed by welding the upper and lower flanges of the primary and secondary beams. However, this connection requires the primary and secondary beams to be perfectly perpendicular, making it unsuitable for rigidly connecting primary and secondary beams in irregularly shaped buildings.

[0003] For example, the building structure of a large-scale special-shaped banquet hall undertaken by our company has an elliptical floor frame structure, and the floor frame structure gradually expands from bottom to top. Among them, the main beams located in the circumferential direction of the frame structure, and the secondary beams located in the radial direction of the frame structure and the main beams of the arc structure cannot be directly connected, so the existing vertical rigid connection method between the main beam and the secondary beam cannot be used for connection. Based on this, our company proposed a rigid connection node structure for the main and secondary beams of the special-shaped frame structure, which can not only ensure the strength and stability of the rigid connection, but also facilitate rapid connection and installation on site. Utility Model Content

[0004] The utility model provides a primary and secondary beam rigid connection node structure to achieve the purpose of rigid connection between steel beams in a special-shaped steel structure frame.

[0005] This application provides the following technical solutions:

[0006] A primary and secondary beam rigid connection node structure includes an inclined column for supporting steel beams, a node assembly is arranged on the inclined column, the node assembly includes several layers of annular plates, and several groups of connection assemblies are arranged obliquely on the circumference of the annular plates. The connection assemblies are used to connect with the primary beam or secondary beam, and the inclination angle of each connection assembly is consistent with the inclination angle of the corresponding rigidly connected primary beam or secondary beam; each connection assembly includes two upper and lower staggered horizontal plates and a vertical plate arranged between the upper and lower horizontal plates. By arranging the upper and lower horizontal plates on different layers of annular plates, a plurality of connection assemblies with different spacings can be combined for connection with steel beams of different heights.

[0007] Beneficial effects:

[0008] 1. By setting up inclined columns to support the steel beams on the circumference of the arc frame and setting node components on the inclined columns, a rigid connection between the main beams and the main beams, and between the main beams and the secondary beams can be achieved; and the connection components set on the node components are set at an angle, and their inclination direction corresponds to the direction of the connected steel beams, which can effectively disperse the load, reduce stress concentration, and make the connection tighter and more stable.

[0009] 2. By setting up multiple layers of annular plates and setting the upper and lower transverse plates on different layers of annular plates, connection components with various spacings can be combined as needed, making them suitable for steel beam structures of different heights, thereby improving the flexibility and adaptability of node components.

[0010] 3. The connection components set on the node components can be pre-set. During installation, you only need to select the corresponding steel beam connection, which facilitates rapid assembly on site, improves construction efficiency and reduces construction difficulty.

[0011] Furthermore, the upper and lower transverse plates are welded to the upper and lower flanges of the corresponding steel beams, and the vertical plates are connected to the webs of the corresponding steel beams through connecting plates and bolts.

[0012] Beneficial effects: The combination of welding and bolt connection can ensure that the connection between the main and secondary beams is more firm and reliable. This combination method can effectively transfer the load and ensure the integrity and stability of the structure.

[0013] Furthermore, it also includes an inclined plate. When the height of the steel beam is less than the height of the vertical plate, the upper horizontal plate is aligned with the upper flange of the steel beam, and the lower horizontal plate is connected to the lower flange of the steel beam through the inclined plate.

[0014] Beneficial effects: The use of inclined plates can adapt to steel beams of different heights. Even if the height of the steel beam is less than the height of the vertical plate, an effective connection can be achieved, thereby ensuring that the connection between the upper and lower horizontal plates and the steel beam flanges remains consistent, ensuring the reliability and stability of the connection; in addition, this design can reduce the additional design work caused by differences in steel beam sizes, especially for the special-shaped steel structure frame of this application, which has a wide variety of steel beam sizes. This connection method is conducive to reducing design costs.

[0015] Furthermore, it also includes an adapter, which is an I-beam structure. One end of the adapter is connected to the connecting assembly, and a connecting plate is provided on the web of the other end of the adapter, and the connecting plate is connected to the steel beam.

[0016] Beneficial effects: Since the steel structure frame of the present application is a special-shaped part, some secondary beams cannot be directly connected to the node components of the inclined columns. The connection can be achieved by setting adapters.

[0017] Furthermore, a reinforcing rib is provided on the web of the adapter which is away from the steel beam and corresponds to the connecting plate.

[0018] Beneficial effects: The use of reinforcing ribs can significantly improve the rigidity of the adapter, reduce bending deformation, and thus enhance the overall stability of the structure.

[0019] Furthermore, reinforcing ribs are provided between adjacent annular plates.

[0020] Beneficial effect: It is beneficial to improve the strength and stability of the annular plate.

[0021] Furthermore, the upper and lower horizontal plates are integrally formed with the annular plate.

[0022] Beneficial effects: It is beneficial to improve the connection strength between the annular plate and the upper and lower transverse plates, and improve the stability and reliability of the node assembly.

[0023] Furthermore, the upper and lower ends of the vertical plate are respectively welded to the upper and lower horizontal plates, and the side of the vertical plate close to the inclined column is welded to the inclined column; the inner side of the annular plate is welded to the inclined column.

[0028] The following is further described in detail through specific implementation methods:

[0029] The symbols in the drawings of the specification include: floor 100, roof 101, reinforcement 200, inclined column 1, node assembly 2, annular plate 21, upper transverse plate 221, lower transverse plate 222, vertical plate 23, inclined plate 3, steel beam 4, secondary beam 41, upper flange 401, lower flange 402, web 403, connecting plate 5, bolt 51, adapter 6.

[0030] Example 1

[0031] A primary and secondary beam rigid connection node structure, which is mainly used for rigid connection between steel beams 4 in special-shaped steel structure buildings. This embodiment shows a special-shaped building, such as Figure 1 As shown, the special-shaped steel structure frame includes an elliptical floor 100 and an elliptical roof 101 eccentrically arranged with respect to the floor 100. Since the floor 100 frame is an arc-shaped structure, the connecting ends of the main beams and the main beams, and the main beams and the secondary beams 41 in the steel structure cannot be in vertical contact to achieve a rigid connection. Based on this, the present application provides a node assembly 2 specifically for the rigid connection between the steel beams 4 in the special-shaped steel structure.

[0032] The above-mentioned heterogeneous steel structure frame also includes an inclined column 1 for supporting the steel beam 4, and a node component 2 is provided on the inclined column 1, such as Figure 2As shown, the node assembly 2 includes several layers of annular plates 21, and the inner ring of each annular plate 21 is welded to the inclined column 1. In this embodiment, in order to improve the strength of the annular plates 21, reinforcing ribs 200 are provided between adjacent annular plates 21; a plurality of groups of connecting assemblies are obliquely provided on the circumference of the annular plate 21, and the connecting assemblies are used to connect with the steel beam 4 (the steel beam 4 includes the main beam or the secondary beam 41), and the inclination angle of each connecting assembly is consistent with the inclination angle of the corresponding main beam or the secondary beam 41.

[0033] Specifically, each connection assembly includes two upper and lower staggered transverse plates, and a vertical plate 23 disposed between the upper transverse plate 221 and the lower transverse plate 222. By placing the upper and lower transverse plates on different layers of annular plates 21, multiple connection assemblies with different spacings can be combined for connection to steel beams 4 at different heights. In this embodiment, the upper transverse plate 221 and the lower transverse plate 222 are integrally formed with the annular plates 21 of the corresponding layers. The upper and lower ends of the vertical plate 23 are welded to the middle of the upper and lower transverse plates, respectively. The side of the vertical plate 23 closest to the inclined column 1 is welded to the inclined column 1.

[0034] When the node assembly 2 is connected to the corresponding steel beam 4, the upper and lower transverse plates of the connection assembly are welded to the upper and lower flanges of the corresponding steel beam 4, and the vertical plate 23 is connected to the web 403 of the corresponding steel beam 4 through the connecting plate 5 and bolts 51. Figure 2 As shown, multiple groups of node components 2 can be set on the inclined column 1, and multiple groups of connection components can be set on each group of node components 2. This embodiment is described by taking the node component 2 on the lowest layer as an example; the node component 2 is provided with a total of five layers of annular plates 21 from top to bottom, and the annular plates 21 on the top three layers constitute a connection component for connecting to the steel beam 4 on the right side of the inclined column 1, and the annular plates 21 on the second, third, and fourth layers constitute another connection component for connecting to the steel beam 4 on the left side of the inclined column 1, and the annular plates 21 on the second, third, fourth, and fifth layers constitute a third group of connection components.

[0035] By setting up multiple layers of annular plates 21 and setting the upper and lower transverse plates on different layers of annular plates 21, the present application can combine connection components with various spacings as needed, thereby making it suitable for steel beam 4 structures of different heights, thereby improving the flexibility and adaptability of the node component 2; and the connection component set on the node component 2 is set at an angle, and its inclination direction corresponds to the direction of the connected steel beam 4, which can effectively disperse the load, reduce stress concentration, make the connection tighter and more stable, and ensure the rigid connection strength.

[0036] Example 2

[0037] The difference between this embodiment and the first embodiment is that Figure 3As shown, it also includes an inclined plate 3. When the height of the steel beam 4 is less than the height of the vertical plate 23, the upper horizontal plate 221 is aligned with the upper flange 401 of the steel beam 4, and the lower horizontal plate 222 is connected to the lower flange 402 of the steel beam 4 through the inclined plate 3. Specifically, in this embodiment, the node assembly 2 includes three layers of annular plates 21. A total of four groups of connection assemblies are provided on the annular plates 21. This embodiment is described by taking one group as an example. The connection assembly located on the right side of the inclined column 1 is provided with an inclined plate 3. The lower horizontal plate 222 of the connection assembly is integrally formed with the annular plate 21 of the second layer. The height of the vertical plate 23 is greater than the height of the steel beam 4. When connecting, the upper horizontal plate 221 is welded to the upper flange 401 of the steel beam 4, the lower horizontal plate 222 is welded to the lower flange 402 of the steel beam 4 through the inclined plate 3, and the vertical plate 23 is connected to the web 403 of the steel beam 4 through the connecting plate 5 and bolts 51.

[0038] The use of the inclined plate 3 can adapt to steel beams 4 of different heights. Even if the height of the steel beam 4 is less than the height of the vertical plate 23, an effective connection can be achieved, thereby ensuring that the connection between the upper and lower horizontal plates and the flanges of the steel beam 4 remains consistent, ensuring the reliability and stability of the connection; in addition, this design can reduce the additional design work caused by the size differences of the steel beams 4, especially for the special-shaped steel structure frame of this application, the steel beams 4 have many sizes, and this connection method is conducive to reducing design costs.

[0039] Example 3

[0040] The difference between this embodiment and the first embodiment is that Figure 4 As shown, the node assembly 2 also includes an adapter 6, which is an I-beam structure. One end of the adapter 6 is connected to the connection assembly, and the other end of the adapter 6 has a connecting plate 5 provided on the web 403. The connecting plate 5 is connected to the steel beam 4. Specifically, in this embodiment, the node assembly 2 is provided with five sets of connecting assemblies, one of which is provided with an I-shaped adapter 6 for connecting to the secondary beam 41. To increase the strength of the adapter 6, a reinforcing rib 200 is provided on the web 403 on the side of the adapter 6 facing away from the secondary beam 41 and corresponding to the connecting plate 5. This helps to improve the rigidity of the connection and reduce bending deformation.
