AI Technical Summary
In traditional I-beam column connection nodes, the stress-bearing area and stress points at the connection between the steel column and the beam are small, which can easily lead to deformation at the connection and affect the stress performance.
Adjacent first and second steel beams are fixedly connected by connectors. The connectors are equipped with first and second connecting blocks, inserts and other structures to evenly distribute the force on the web and flange of the steel column, increasing the stress points and stress area.
By designing the connectors, the stress on the steel beams and columns is evenly distributed, making the connection more stable, avoiding deformation caused by single-point stress, and enhancing the overall structural stability.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0024] Example: This example discloses a prefabricated steel structure for construction sites, such as... Figures 1-7 As shown, the present invention includes: a steel column 1 and a first steel beam 2 and a second steel beam 3 connected to adjacent sides of the steel column 1, with two of each; wherein the steel column 1, the first steel beam 2, and the second steel beam 3 are all I-beam structures, the first steel beam 2 and the second steel beam 3 are the same size, the first steel beam 2 is connected to the web surface of the steel column 1, and the second steel beam 3 is connected to the flange surface of the steel column 1; and four connectors 4 are fixedly connected to the steel column 1, the first steel beam 2, and the second steel beam 3 by bolt assemblies, respectively installed between adjacent first steel beam 2 and second steel beam 3; compared with the prior art in which the first steel beam 2 and the second steel beam 3 are independently installed on the steel column 1, this embodiment uses connectors 4 to fix the steel column 1, the first steel beam 2, and the second steel beam 3 into a whole, and the first steel beam 2 and the second steel beam 3 are also fixedly connected to each other, making the overall structure more stable.
[0025] like Figures 2-6As shown, the connecting piece 4 is provided with a first connecting hole 403, and the web of the steel column 1 is provided with a first mounting hole 102 matched with the first connecting hole 403. The first mounting hole 102 is connected with the first connecting hole 403 through a bolt assembly, and the two connecting pieces 4 on the two sides of the web of the steel column 1 are fixedly connected through the same bolt assembly. The connecting piece 4 is provided with a first connecting block 401 which is integrally formed with the connecting piece 4. The first connecting block 401 is in close contact with and fixedly connected with the web of the first steel beam 2. The first connecting block 401 is provided with a second connecting hole 404, and the first steel beam 2 is provided with a second mounting hole 201 matched with the second connecting hole 404. The second connecting hole 404 is connected with the second mounting hole 201 through a bolt assembly, and the two first connecting blocks 401 on the two sides of the web of the first steel beam 2 are fixedly connected through the same bolt assembly. The connecting piece 4 is provided with a second connecting block 402 which is integrally formed with the connecting piece 4. The second connecting block 402 is in close contact with and fixedly connected with the web of the second steel beam 3. The second connecting block 402 is provided with a third connecting hole 405, and the second steel beam 3 is provided with a third mounting hole 302 matched with the third connecting hole 405. The third connecting hole 405 is connected with the third mounting hole 302 through a bolt assembly, and the two second connecting blocks 402 on the two sides of the web of the second steel beam 3 are fixedly connected through the same bolt assembly.
[0026] Further, the width of the first connecting block 401 is the same as the width of the web of the first steel beam 2. The first connecting block 401 is in close contact with the surface of the flange of the first steel beam 2, so that the flange of the first steel beam 2 can share the stress of the web, avoiding deformation caused by excessive stress on the web. The width of the second connecting block 402 is the same as the width of the web of the second steel beam 3. The second connecting block 402 is in close contact with the surface of the flange of the second steel beam 3.
[0027] As shown in Figure 2 and Figure 5 , the connecting piece 4 is provided with a pair of upper and lower symmetrical plug blocks 406. The plug block 406 is arranged between the flange of the first steel beam 2 and the flange of the steel column 1, and the surface of the plug block 406 is in close contact with the surfaces of the two flanges, increasing the compactness and stability of the structure between the connecting piece 4 and the steel column 1 and the first steel beam 2. The web of the steel column 1 is provided with a plug hole 103 matched with the plug block 406. The plug block 406 is inserted into the plug hole 103, increasing the stress points and stress area on the steel column 1, and avoiding deformation caused by excessive stress at a certain point.
[0028] Further, the flange of the steel column 1 is provided with a limiting groove 101, and the connecting piece 4 is provided with a plug groove 407 matched with the limiting groove 101. When the connecting piece 4 is installed on the steel column 1, the plug groove 407 and the limiting groove 101 are connected together, so that the flange of the steel column 1 can share the stress of the web, and the flange and the web of the steel column 1 can be stressed at the same time. Both of them share the stress evenly, avoiding deformation of the web.
[0029] Furthermore, 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 to cooperate 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 second steel beam 3 is further stabilized.
[0030] like Figures 5-7 As shown, a fixing block 408 is fixedly connected to the connector 4, and a pair of brackets 409 are fixedly connected to the fixing block 408, respectively for supporting the bottom of the first steel beam 2 and the second steel beam 3. Each bracket 409 includes a connecting column 4091, which is fixedly connected to the fixing block 408 by an internal hex bolt. A support plate 4093 is vertically fixedly connected to one end of the connecting column 4091. The length of the support plate 4093 is between 0.3 and 0.5 m. The surface of the support plate 4093 contacts the bottom surfaces of the first steel beam 2 and the second steel beam 3, providing auxiliary support for them. Furthermore, the connector 4 has a limiting protrusion 410 on its surface, and the connecting column 4091 has a limiting groove 4092 that engages with the limiting protrusion 410. The limiting protrusion 410 connects to the limiting groove 4092, reducing the stress on the internal hex bolt and increasing the connection stability between the bracket 409 and the fixing block 408.
[0031] In this embodiment, the steel column 1, the first steel beam 2, and the second steel beam 3 are connected together by the connector 4, which increases the stability of the overall structure and increases the stress points and stress areas at the connection points between the steel beams and the steel column 1. Compared with the prior art where only the web of the steel column 1 bears the stress, in this embodiment, the web and flanges of the steel column 1, the first steel beam 2, and the second steel beam 3 all bear the stress through the connector 4, increasing the number of stress-bearing components and avoiding deformation caused by excessive stress on the web.
