Description

Technical Field

[0001] This utility model belongs to the field of steel structure technology, specifically relating to an interactive node for multiple hanging beams. Background Technology

[0002] With the advancement of steel structure technology, modern building structures can not only meet functional requirements, but also showcase elegant aesthetic designs.

[0003] In multi-story and high-rise steel structure buildings, the primary and secondary beam joints are the most common connection nodes. In existing technologies, corbels are used to connect the primary beams and steel beams. This method features a simple joint structure, clear force transmission, and ensures the safety and stability of the connection structure while meeting the building's functional requirements. For example, Chinese Patent No. CN211571978U, published on December 23, 2019, discloses a utility model patent entitled "A Connection Node Between Unequal Height Box-Type Steel Beams and H-Shaped Primary Beams."

[0004] However, the complexity of structural design also increases in steel structure buildings. For example, in some structures with cantilevered platforms, multiple beams intersect at a single point and are suspended by columns, specifically multiple secondary beams fixed to the main beams via corbels. When using traditional construction methods, this joint design encounters the following problems: collisions are unavoidable at the intersection of multiple corbels, preventing the secondary beams from being smoothly installed on the main beams; due to the multiple corbels on the main beams, the number of components constituting the corbels increases, leading to increased welding workload, which can easily cause welding deformation, and the interlacing of welds further complicates the welding process. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art, and to provide a multi-beam interactive node, in which several corbels and a single steel plate on the same side of the main beam form a connecting unit, and each corbel is fixedly connected to the corresponding secondary beam, so that multiple secondary beams can interact on the same main beam through corbels, which is suitable for steel structure buildings with complex structural design.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A multi-beam interconnection node includes a main beam, secondary beams, and a corbel. The main beam includes an upper flange plate, a web plate, and a lower flange plate, with the web plate welded between the upper and lower flange plates. The secondary beam includes an upper flange plate, a web plate, and a lower flange plate, with the web plate welded between the upper and lower flange plates. The corbel includes a web plate and a lower flange plate, with the lower flange plate welded to the bottom of the web plate.

[0008] Its features include a steel plate, a single steel plate and several corbels on the same side of the main beam forming a connecting unit, the steel plate being welded to the top of the corbel web, the steel plate and the corbel being welded to the main beam, the steel plate having a connecting surface, the upper flange plate of the secondary beam being welded to the connecting surface, the web plate of the secondary beam being fixed to the web plate of the corbel, and the lower flange plate of the secondary beam being welded to the lower flange plate of the corbel.

[0009] Furthermore, connecting units are provided on both sides of the main beam, forming connecting unit one and connecting unit two, so that secondary beams can be installed on both sides of the main beam.

[0010] Furthermore, the installation heights of connection unit one and connection unit two differ: In connection unit one, the upper flange plate of the main beam has an installation opening, and a steel plate is welded into the installation opening. The steel plate is used to weld the steel column, which can appropriately increase the connection area between the steel column and the main beam, ensuring an effective connection between the steel column and the main beam. In connection unit two, the steel plate is welded to the web plate of the main beam.

[0011] Furthermore, based on the primary and secondary relationship of the secondary beams, the length of the corbel is extended so that the corbels in the connecting unit include primary corbels and secondary corbels.

[0012] In connection unit one, the web plates of the main corbel and the secondary corbel are both welded to the web of the main beam, and the lower flange plates of the main corbel and the secondary corbel are both welded to the web of the main beam. At the same time, the lower flange plates of the secondary corbel and the web plates of the main corbel are welded together.

[0013] In connection unit two, the web plates of the main corbel and the secondary corbel are both welded to the web of the main beam. The lower flange plate of the main corbel is welded to the lower flange plate of the main beam, and the lower flange plate of the secondary corbel is welded to the web of the main beam and the web plate of the main corbel.

[0014] Furthermore, in connection unit one, a reinforcing plate one is welded between the lower flange plate of the main corbel and the lower flange plate of the secondary corbel, and a reinforcing plate two is welded between the lower flange plate of the main corbel and the lower flange plate of the main beam. This increases the connection strength between connection unit one and the main beam, and at the same time makes connection unit one a and connection unit two b fixedly connected, increasing the node strength and ensuring the safety of the structure.

[0015] Furthermore, in connection unit two, a reinforcing plate three is welded between the lower flange plate of the secondary corbel and the lower flange plate of the main beam. At the same time, a reinforcing plate four is welded between the steel plate in connection unit two and the steel plate in connection unit one, thereby increasing the connection strength between connection unit two and the main beam and ensuring the safety of the structure.

[0016] Furthermore, a connecting plate is provided between the secondary beam web and the corbel web, and fixing bolts are provided between the connecting plate and the secondary beam web, and between the connecting plate and the corbel web. The fixing bolts are threaded with nuts to achieve a welded connection between the corbel and the secondary beam.

[0017] Furthermore, welds are provided between the upper flange plate of the secondary beam and the connecting surface, and between the lower flange plate of the secondary beam and the lower flange plate of the corbel. The web plate of the secondary beam and the web plate of the corbel are both provided with grooves, and the welds pass through the grooves to increase the strength of the connection between the secondary beam and the corbel.

[0018] Furthermore, connecting strips are welded between the upper flange plate and the connecting surface of the secondary beam, and between the lower flange plate of the secondary beam and the lower flange plate of the corbel, to facilitate welding of the secondary beam and the corbel.

[0019] Furthermore, a horizontal reinforcing plate five is welded to the web of the main beam. A reinforcing plate six is ​​welded between the reinforcing plate five and the upper flange plate of the main beam, and between the reinforcing plate five and the lower flange plate of the main beam. Welding strips are welded to the upper flange plate of the main beam. The reinforcing plate six at the top is welded to the welding strips, which can increase the strength of the main beam, prevent the main beam from deforming, and meet the requirement that multiple secondary beams interact on the same main beam through corbels.

[0020] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0021] The bracket of this utility model is made by welding the bracket web and the bracket lower flange plate. A steel plate is welded to the top of the bracket web of multiple brackets located on the same side of the main beam, so that several brackets on the same side of the main beam and a single steel plate form a connection unit. Each bracket is fixedly connected to the corresponding secondary beam, so that multiple secondary beams can interact on the same main beam through the brackets. It is suitable for steel structure buildings with complex structural designs.

[0022] Furthermore, several corbels on the same side of the main beam are welded to the same steel plate. The steel plate can serve as the upper flange plate of multiple corbels, making the upper flange plates of multiple corbels an integral structure. This eliminates the need to weld the upper flange plates of multiple corbels to each other, reducing welding difficulty and the amount of welding. It also ensures that the top of the corbel web plates of multiple corbels are at the same height, improving manufacturing accuracy, avoiding welding deformation, and preventing the welds from intersecting.

[0044] like Figures 1 to 9 As shown, this utility model provides a multi-beam interactive node, including a main beam 1, a secondary beam 2, and a corbel, with a steel column 5 installed on the main beam 1.

[0045] The main beam 1 includes an upper flange plate 11, a web plate 12, and a lower flange plate 13. The web plate 12 is welded between the upper flange plate 11 and the lower flange plate 13. At this time, the diameter of the steel column 5 section is larger than the width of the upper flange plate 11, which makes it impossible for the steel column 5 to be directly welded and fixed to the upper flange plate 11.

[0046] The secondary beam 2 includes an upper flange plate 21, a web plate 22, and a lower flange plate 23. The web plate 22 is welded between the upper flange plate 21 and the lower flange plate 23.

[0047] The corbel includes a corbel web 31 and a corbel lower flange 32, with the lower flange 32 welded to the bottom of the corbel web 31. A single steel plate 4 and several corbels on the same side of the main beam 1 form a connecting unit. Connecting units are provided on both sides of the main beam 1, forming connecting unit 1a and connecting unit 2b, allowing secondary beams to be installed on both sides of the main beam 1. The steel plate 4 is welded to the top of the corbel web 31, and the steel plate 4 and corbels are welded to the main beam 1. The steel plate 4 has a connecting surface 41. The upper flange 21 of the secondary beam is welded to the connecting surface 41. The secondary beam web 22 is fixed to the corbel web 31, and the lower flange 23 of the secondary beam is welded to the lower flange 32 of the corbel.

[0048] The installation heights of connection unit 1a and connection unit 2b are different: In connection unit 1a, the upper flange plate 11 of the main beam has an installation opening 14, and the steel plate 4 is welded into the installation opening 14. The steel plate 4 is used to weld the steel column 5, which can appropriately expand the connection area 41 between the steel column 5 and the main beam 1, ensuring an effective connection between the steel column 5 and the main beam 1. In connection unit 2b, the steel plate 4 is welded to the web plate 12 of the main beam.

[0049] Based on the primary and secondary relationship of the secondary beam 2, the length of the corbel is extended so that the corbel in the connecting unit includes a primary corbel 3b and a secondary corbel 3a, with the length of the primary corbel 3b being greater than the length of the secondary corbel 3a, so that the primary corbel 3b is located between the two secondary corbels 3a. For example... Figure 4 In connection unit 1a, the web plate 31 of the main corbel 3b and the web plate 31 of the secondary corbel 3a are both welded to the web plate 12 of the main beam. The lower flange plate 32 of the main corbel 3b and the lower flange plate 32 of the secondary corbel 3a are also welded to the web plate 12 of the main beam. Simultaneously, the lower flange plate 32 of the secondary corbel 3a and the web plate 31 of the main corbel 3b are welded together. Figure 5 In connection unit 2b, the web plate 31 of the main corbel 3b and the web plate 31 of the secondary corbel 3a are both welded to the web plate 12 of the main beam. The lower flange plate 32 of the main corbel 3b is welded to the lower flange plate 13 of the main beam. The lower flange plate 32 of the secondary corbel 3a is welded to the web plate 12 of the main beam and the web plate 31 of the main corbel 3b.

[0050] To ensure effective connection of the nodes, some areas need to be expanded, requiring increased node strength. In connection unit 1a, a reinforcing plate 6 is welded between the lower flange plate 32 of the main corbel 3b and the lower flange plate 32 of the secondary corbel 3a, and a reinforcing plate 7 is welded between the lower flange plate 32 of the main corbel 3b and the lower flange plate 13 of the main beam. This increases the connection strength between connection unit 1a and the main beam 1, ensuring structural safety. In connection unit 2b, a reinforcing plate 9 is welded between the lower flange plate 32 of the secondary corbel 3a and the lower flange plate 13 of the main beam. Simultaneously, a reinforcing plate 8 is welded between the steel plate 4 in connection unit 2b and the steel plate 4 in connection unit 1a. This increases the connection strength between connection unit 2b and the main beam 1, while also ensuring a fixed connection between connection unit 1a and connection unit 2b, increasing node strength and ensuring structural safety.

[0051] A connecting plate 10 is provided between the secondary beam web 22 and the corbel web 31. A fixing bolt 101 is provided between the connecting plate 10 and the secondary beam web 22, and between the connecting plate 10 and the corbel web 31. The fixing bolt 101 is threaded with a nut 102 to realize the welding connection between the corbel and the secondary beam 2.

[0052] Welds 35 are provided between the upper flange plate 21 and the connecting surface 41 of the secondary beam, and between the lower flange plate 23 of the secondary beam and the lower flange plate 32 of the corbel. Both the web plate 22 of the secondary beam and the web plate 31 of the corbel have grooves 33 through which the welds 35 pass, increasing the strength of the connection between the secondary beam 2 and the corbel. Connecting strips 34 are welded between the upper flange plate 21 and the connecting surface 41 of the secondary beam, and between the lower flange plate 23 of the secondary beam and the lower flange plate 32 of the corbel, facilitating welding between the secondary beam 2 and the corbel.

[0053] Considering that multiple secondary beams interact with the same main beam via corbels, this design is suitable for steel structure buildings with complex structural designs. To prevent deformation of the main beam 1, such as... Figure 3 As shown, a horizontal reinforcing plate 17 is welded to the web plate 12 of the main beam. A reinforcing plate 15 is welded between the reinforcing plate 17 and the upper flange plate 11 of the main beam, and between the reinforcing plate 17 and the lower flange plate 13 of the main beam, so that the reinforcing plate 15 is distributed vertically. A welding strip 16 is welded to the upper flange plate 11 of the main beam. The upper reinforcing plate 15 and the welding strip 16 are welded and fixed, which can increase the width of the upper reinforcing plate 15, thereby improving the strength of the main beam 1, preventing the main beam 1 from deforming, and meeting the installation requirements of multiple secondary beams 2 interconnected on the same main beam 1 through corbels.
