Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an end connection structure for steel components. Background Technology

[0002] With the continuous advancement of modern construction technology, steel structures have been widely used in many fields such as architecture, bridges, and machinery due to their comprehensive advantages, including light weight, high strength, factory manufacturing, quick installation, short construction period, and good seismic performance. For example, in high-rise buildings, steel structures can effectively reduce the structural weight and increase the usable space of the building; in the construction of long-span bridges, steel structures can achieve larger spans while ensuring the stability and safety of the structure.

[0003] Currently, welding is a common method for connecting steel components. It has advantages such as high connection strength and good sealing. However, the welding process generates large welding stress and deformation, which can easily lead to a decline in the local performance of the components. In addition, in some structures that need to be disassembled or modified, the dismantling of welded connections is difficult. Therefore, we provide a steel component end connection structure. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a steel component end connection structure, which solves the problem that welding connection is a common steel component connection method. It has advantages such as high connection strength and good sealing performance. However, the welding process generates large welding stress and deformation, which can easily lead to a decline in the local performance of the component. In addition, in some structures that need to be disassembled or modified, the dismantling of welded connections is a technical problem with great difficulty.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A steel component end connection structure includes an I-beam, the end of which is provided with a connector for connection. The connector includes two pressure plates, which are respectively disposed at the top and bottom of the I-beam. A connecting plate is fixedly connected between the two pressure plates. Slots for limiting the movement of the I-beam are provided on both sides of the connecting plate.

[0008] Preferably, the edge of the pressure plate adjacent to the I-beam is provided with an edge weld.

[0009] The technical advantage of adopting the above-mentioned further solution is that it has better disassembly and flexibility compared to a fully welded structure.

[0010] Preferably, the pressure plate is fixedly connected to the side of the I-beam with polyurethane foam.

[0011] The technical effect of adopting the above-mentioned further solution is that polyurethane foam has good plasticity and can automatically adjust its shape according to the pressure between the pressure plate and the I-beam, so that the pressure between the pressure plate and the I-beam is more evenly distributed.

[0012] Preferably, the pressure plate is threaded with high-strength nut assemblies at its four corners, and four long bolts are threaded with the center of the surface of the pressure plate. The connecting plate is threaded with side nut assemblies at its four corners. The high-strength nut assemblies are used for the connection between the I-beam and the pressure plate. The long bolts are used for the connection between the I-beam, the connecting plate, and the pressure plate. The side nut assemblies are used for the connection between the connecting plate and the I-beam.

[0013] The technical effect of adopting the above-mentioned further solution is that when the connection part of the device is under load, the high-strength nut assembly first bears part of the shear force and tension force. The preload of the high-strength nut assembly tightly connects the pressure plate and the I-beam together. When the external force gradually increases and the high-strength nut assembly reaches a certain load-bearing capacity, the local long bolts and side nut assemblies begin to bear excessive external force. Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention incorporates polyurethane foam and edge welds. The polyurethane foam has good plasticity and can automatically adjust its shape according to the pressure between the pressure plate and the I-beam, making the pressure between the pressure plate and the I-beam more evenly distributed. Compared with a fully welded structure, the edge welds have better disassembly and flexibility.

[0016] This invention, by setting up a high-strength nut assembly, long bolts, and side nut assemblies, allows the high-strength nut assembly to initially bear part of the shear and tensile forces when the connection part of the device is under load, thanks to the coordinated action of these components. The preload of the high-strength nut assembly tightly connects the pressure plate and the I-beam together. As the external force gradually increases and the high-strength nut assembly reaches a certain load-bearing capacity, the long bolts and side nut assemblies in certain areas begin to bear excessive external forces.

[0022] This application provides a steel component end connection structure. By incorporating polyurethane foam and side welds, the polyurethane foam, with its excellent plasticity, automatically adjusts its shape according to the pressure between the pressure plate and the I-beam, resulting in a more uniform pressure distribution. Compared to a fully welded structure, the side welds offer better disassembly and flexibility. Through the coordinated action of high-strength nut assemblies, long bolts, and side nut assemblies, when the connection point is under load, the high-strength nut assemblies initially bear part of the shear and tensile forces. The preload of the high-strength nut assemblies tightly connects the pressure plate and the I-beam. As the external force gradually increases and the high-strength nut assemblies reach a certain load-bearing capacity, the long bolts and side nut assemblies begin to bear excessive external forces. Example

[0023] The technical solution in this application embodiment effectively addresses the problem that welding is a common method of connecting steel components, offering advantages such as high connection strength and good sealing. However, the welding process generates significant welding stress and deformation, which can easily lead to a decline in the local performance of the components. Furthermore, in some structures that require disassembly or modification, the removal of welded connections presents a significant technical challenge. The overall approach is as follows:

[0024] like Figures 1 to 3 To address the problems existing in the prior art, this utility model provides a steel component end connection structure, including an I-beam 1. A connector 2 is provided at the end of the I-beam 1 for connection. The connector 2 includes two pressure plates 21, which are respectively located at the top and bottom of the I-beam 1. A connecting plate 24 is fixedly connected between the two pressure plates 21. Slots 25 for limiting the movement of the I-beam 1 are provided on both sides of the connecting plate 24. High-strength nut assemblies 26 are threadedly connected to the four corners of the pressure plates 21. Four long bolts 27 are threadedly connected to the center of the surface of the pressure plates 21. Side nut assemblies 28 are threadedly connected to the four corners of the surface of the connecting plate 24. The high-strength nut assemblies 26 are used for the connection between the I-beam 1 and the pressure plates 21. The long bolts 27 are used for the connection between the I-beam 1, the connecting plate 24, and the pressure plates 21. The side nut assemblies 28 are used for the connection between the connecting plate 24 and the I-beam 1.

[0025] By adopting the above technical solution, when the connection part of the device is under load, the high-strength nut assembly 26 first bears part of the shear force and tension force. The pre-tightening force of the high-strength nut assembly 26 tightly connects the pressure plate 21 and the I-beam 1 together. When the external force gradually increases, after the high-strength nut assembly 26 reaches a certain bearing capacity, the local long bolts 27 and the side nut assembly 28 begin to bear excessive external force.

[0026] Specifically, a side weld 23 is provided at the edge of the side of the pressure plate 21 adjacent to the I-beam 1, and polyurethane foam 22 is fixedly connected to the side of the pressure plate 21 adjacent to the I-beam 1.

[0027] By adopting the above technical solution, the edge weld 23 will ultimately play its role, and the edge weld 23 will evenly transmit the external force to the entire connection area, so that the steel components can work together to resist the load. In addition, when it is necessary to repair, replace or modify the structure of the I-beam 1, the bolts can be removed first, and then the edge weld 23 can be treated to easily separate the I-beam 1. Compared with the fully welded structure, it has better disassembly and flexibility. The polyurethane foam 22 has good plasticity and can automatically adjust its shape according to the pressure between the pressure plate 21 and the I-beam 1, so that the pressure between the pressure plate 21 and the I-beam 1 is more evenly distributed.

[0028] Working principle: In use, the steel plate in the middle of the two I-beams 1 that need to be connected at both ends is inserted into the slots 25 on both sides of the connecting plate 24. At this time, the I-beam 1 is located between the two pressure plates 21. The corners of the pressure plates 21 are connected to the I-beam 1 by the high-strength nut assembly 26. After the connection is completed, the middle surface of the pressure plate 21 is connected to the I-beam 1 and the connecting plate 24 by the long bolt 27. Finally, the connecting plate 24 is connected to the I-beam 1 by the side nut assembly 28. After the device is connected, the edge of the pressure plate 21 is connected to the I-beam 1 by the side weld 23. When the connection part of the device is under load, the high-strength nut assembly 26 first bears part of the shear force and tension force. The preload of the high-strength nut assembly 26 connects the pressure plate 21 and the I-beam. 1. When the external force gradually increases and the high-strength nut assembly 26 reaches a certain load-bearing capacity, the local long bolts 27 and side nut assemblies 28 begin to bear excessive external force. Finally, the side weld 23 begins to play its role. The side weld 23 evenly transmits the external force to the entire connection area, so that the steel components work together to resist the load. In addition, when it is necessary to repair, replace or modify the structure of the I-beam 1, the bolts can be removed first, and then the side weld 23 can be treated to easily separate the I-beam 1. Compared with the fully welded structure, it has better disassembly and flexibility. The polyurethane foam 22 has good plasticity and can automatically adjust its shape according to the pressure between the pressure plate 21 and the I-beam 1, so that the pressure between the pressure plate 21 and the I-beam 1 is more evenly distributed.

[0029] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
