[0002] With the rapid development of steel structures in recent years, prefabricated steel structures have gradually come into people's view. Prefabricated steel structure buildings can save construction time, reduce construction costs, and reduce construction waste, and each component can be reused, which is more environmentally friendly than traditional concrete structures. The components processed uniformly in the factory have high precision and ensure reliable and effective connection of each component.

[0003] In traditional I-beam column connection joints, the assembly method between the steel column and the cross beam is fixed connection by bolts. For building structures with higher strength requirements, the connection joint between the steel column and the cross beam is subjected to greater force, but the stress area is small and the stress action points are few, which easily leads to deformation at the connection and affects the stress performance of the connection point.

[0025] As Figures 2-6As shown in the figure, the connecting member 4 is provided with a first connection hole 403, and the web of the steel column 1 is provided with a first mounting hole 102 that cooperates with the first connection hole 403. The first mounting hole 102 is connected to the first connection hole 403 through a bolt assembly. Moreover, the two connecting members 4 on both sides of the web of the steel column 1 are fixedly connected through the same set of bolt assemblies. The connecting member 4 is provided with a first connection block 401, and the first connection block 401 is integrally formed with the connecting member 4. The first connection block 401 is attached to and fixedly connected to the web of the first steel beam 2; the first connection block 401 is provided with a second connection hole 404, and the first steel beam 2 is provided with a second mounting hole 201 that cooperates with the second connection hole 404. The second connection hole 404 is connected to the second mounting hole 201 through a bolt assembly. Moreover, the two first connection blocks 401 on both sides of the web of the first steel beam 2 are fixedly connected through the same set of bolt assemblies; the connecting member 4 is provided with a second connection block 402, and the second connection block 402 is integrally formed with the connecting member 4.

Moreover, the two second connection blocks 402 on both sides of the web of the second steel beam 3 are fixedly connected through the same set of bolt assemblies.

[0026] Furthermore, the width of the first connection block 401 is the same as the width of the web of the first steel beam 2, and the first connection block 401 is attached to the surface of the flange of the first steel beam 2, so that the flange of the first steel beam 2 can share the force of the web and avoid deformation of the web due to excessive force; the width of the second connection block 402 is the same as the width of the web of the second steel beam 3, and the second connection block 402 is attached to the surface of the flange of the second steel beam 3.

[0027] As Figure 2 and Figure 5 shown in the figure, the connecting member 4 is provided with a pair of insertion blocks 406 that are symmetrically arranged up and down. The insertion blocks 406 are arranged between the flange of the first steel beam 2 and the flange of the steel column 1, and the surface of the insertion blocks 406 is attached to the surfaces of the two flanges, increasing the structural compactness and stability between the connecting member 4, the steel column 1, and the first steel beam 2. Moreover, the web of the steel column 1 is provided with a jacking hole 103 that cooperates with the insertion blocks 406. By inserting the insertion blocks 406 into the jacking hole 103, the force application points and force application area on the steel column 1 are increased, and deformation caused by excessive force at a certain point is avoided..

[0028] Furthermore, a limiting groove 101 is provided on the flange of the steel column 1, and the connecting member 4 is provided with a slot 407 that cooperates with the limiting groove 101. When the connecting member 4 is installed on the steel column 1, it is connected together through the slot 407 and the limiting groove 101, so that the flange of the steel column 1 can share the force of the web, enabling the flange and the web of the steel column 1 to be stressed simultaneously, and the two share the force evenly, avoiding web deformation.

[0029] Further, a limiting block 411 is fixedly connected to the second connecting block 402, and a limiting hole 301 is provided on the second steel beam 3 and is cooperatively connected with the limiting block 411. By connecting the limiting block 411 in the limiting hole 301, the stress points and stress area of the second steel beam 3 are increased, and the stability of the second steel beam 3 is further enhanced.

[0030] As Figures 5-7 shown, a fixing block 408 is fixedly connected to the connecting member 4, and a pair of brackets 409 are fixedly connected to the fixing block 408 and are respectively used for supporting the bottoms of the first steel beam 2 and the second steel beam 3; wherein, the bracket 409 includes a connecting column 4091, the connecting column 4091 is fixedly connected to the fixing block 408 through an internal hexagonal bolt, and one end of the connecting column 4091 is vertically and fixedly connected with a supporting plate 4093, wherein, the length of the supporting plate 4093 is between 0.3 - 0.5 m; the surface of the supporting plate 4093 is in contact with the bottom surfaces of the first steel beam 2 and the second steel beam 3, playing a role in auxiliary supporting the first steel beam 2 and the second steel beam 3. Further, a limiting rib 410 is provided on the surface of the connecting member 4, and a limiting groove 4092 is provided on the connecting column 4091 and is cooperatively connected with the limiting rib 410. By connecting the limiting rib 410 in the limiting groove 4092, the stress on the internal hexagonal bolt is reduced, and the connection stability between the bracket 409 and the fixing block 408 is increased.

[0031] In this embodiment, the steel column 1, the first steel beam 2 and the second steel beam 3 are connected together through the connecting member 4, increasing the stability of the overall structure, and increasing the stress points and stress area of the connection points between the steel beam and the steel column 1. Compared with the prior art where only the web of the steel column 1 bears stress, in this embodiment, through the setting of the connecting member 4, the webs and flanges of the steel column 1, the first steel beam 2 and the second steel beam 3 all bear stress, increasing the stress-bearing components and avoiding deformation caused by excessive stress on the web.
