[0003] In the steel structure system, the beam-column connection node is particularly important. Commonly used steel structure components include H-shaped steel, square pipes, round pipes, etc. In some steel structures, in order to ensure aesthetics, cylindrical columns are required as load-bearing support columns, and most of the commonly used crossbeams in steel structures are H-shaped steel beams. When connecting the H-shaped steel beam to the cylindrical column, since the side surface of the cylindrical column is an arc surface and the end surface of the H-shaped steel beam is a plane, when the two are connected, the installation of the structural node is relatively inconvenient, and generally welding is required for fixing. Welding at high altitudes is difficult and the welding quality is not easy to guarantee, affecting the construction efficiency. Therefore, this application proposes a beam-column connection node to solve the above problems. Content of the Utility Model

[0023] In this embodiment, in combination with Figures 1 to 5 this embodiment is described. This embodiment provides a beam-column connection node, which includes an H-shaped steel beam 1, a cylindrical column 2, and an I-shaped connecting member 3. The I-shaped connecting member 3 is welded to the cylindrical column 2. In this example, three I-shaped connecting members 3 are provided and welded to the cylindrical column 2 in a circumferential distribution. A first flat plate 4 is welded to one end face of the I-shaped connecting member 3, and a second flat plate 5 is welded to one end of the H-shaped steel beam 1. Through holes 6 are arranged in a matrix on both the first flat plate 4 and the second flat plate 5. Bolts 7 pass through the through holes 6 to fix the first flat plate 4 and the second flat plate 5 together, thereby fixing the H-shaped steel beam 1 and the I-shaped connecting member 3 together. And the planar shape of the I-shaped connecting member 3 is trapezoidal, and the size of the surface of the I-shaped connecting member 3 that fits the first flat plate 4 is the same as the size of the first flat plate 4.

[0024] One side of the I-shaped connecting member 3 is arc-shaped, and the arc-shaped side of the I-shaped connecting member 3 is welded to the cylindrical column 2. Further, an arc-shaped plate 8 is welded to the arc-shaped side of the I-shaped connecting member 3. The inner arc radius of the arc-shaped plate 8 is the same as the radius of the cylindrical column 2. After the arc-shaped plate 8 is fitted to the cylindrical column 2, it is welded. The arc-shaped plate 8 and the first flat plate 4 are pre-welded to the I-shaped connecting member 3 in the factory, saving assembly time.

[0025] As Figure 1 , 5 shown, further, in order to improve the precision of the I-shaped connecting member 3 and facilitate the installation of the I-shaped connecting member 3, a support ring 9 is also sleeved on the cylindrical column 2, and the support ring 9 is welded to the cylindrical column 2. Specifically, the support ring 9 includes an annular plate 91 and a sleeve ring 92 that are integrally connected. The sleeve ring 92 is welded to the cylindrical column 2. The lower surface of the I-shaped connecting member 3 fits the upper surface of the annular plate 91. And in order to improve the support strength of the annular plate 91, a plurality of angle irons 93 distributed in a circumference are welded between the bottom surface of the annular plate 91 and the outer side surface of the sleeve ring 92, and the angle irons 93 are distributed in a circumference.

[0026] The working principle of the present utility model is as follows: The I-shaped connector 3 is welded to the cylinder 2, so that the connecting surface is changed from an arc surface to a flat surface. The first flat plate 4 is welded to the I-shaped connector 3, and the second flat plate 5 is welded to the end face of the H-shaped steel. The two flat plates are connected by bolts 7 to realize the bolted assembly of the H-shaped steel and the cylinder 2. It can be pre-welded in the factory, reducing the high-altitude welding workload, improving the assembly accuracy of the H-shaped steel and the cylinder 2, reducing the construction difficulty, saving the construction period, ensuring the stiffness and bearing capacity of the connection node, and being beneficial to the popularization and application of large-span space structures.
