[0042] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0043] This embodiment provides a steel structure beam-column connection structure that can be quickly installed and is used for connecting steel beams and steel columns.

[0044] As shown in Figure 1, a specific implementation of a steel structure beam-column connection structure provided in this embodiment includes: a steel column 1 and a steel beam 5; the side of the steel column 1 is provided with a supporting plate 2 extending outward; the steel beam 5 is supported on the supporting plate 2 of the steel column 1, and a clamping structure 9 inserted in the vertical direction is provided between the bottom surface of the steel beam 5 and the upper surface of the supporting plate 2.

[0045] When in use, the supporting plate 2 extending outward from the side of the steel column 1 supports the steel beam 5, and the steel beam 5 is positioned by the clamping structure 9 between the bottom surface of the steel beam 5 and the upper surface of the supporting plate 2 to prevent the steel beam 5 and the steel column 1 from moving relative to each other. The steel structure beam-column connection structure provided in this embodiment improves construction efficiency because the supporting plate 2 and the clamping structure 9 are both manufactured in the factory and only installation and partial welding are performed on site, thereby solving the problem of low assembly efficiency of traditional steel structure connection methods.

[0046] As shown in FIG1 , in the steel structure beam-column connection structure provided in this embodiment, the steel beam 5 has a vertical web 6, an upper flange 7 horizontally connected to the upper end of the web 6, and a lower flange 8 horizontally connected to the lower end of the web 6. The support plates 2 comprise two sets of support plates spaced apart from each other, wherein an upper support plate 3 supports the bottom of the upper flange 7 of the steel beam 5, and a lower support plate 4 supports the bottom of the lower flange 8 of the steel beam 5. The upper support plate 3 supports the bottom of the upper flange 7 of the steel beam 5, while the lower support plate 4 supports the bottom of the lower flange 8 of the steel beam 5, thereby supporting the web 6 of the steel beam 5 and the steel beam 5 as a whole. Alternatively, the steel beam 5 may have a rectangular cross-section, with the upper support plate 3 supporting the inner side of the top plate of the steel beam 5 and the lower support plate 4 supporting the outer side of the bottom plate of the steel beam 5.

[0047] As shown in FIG2 , in the steel structure beam-column connection structure provided in this embodiment, the upper supporting plates 3 are provided in two spaced-apart sections, with the web 6 of the steel beam 5 being accommodated between the two upper supporting plates 3. The web 6 of the steel beam 5 is clamped between the two upper supporting plates 3, preventing the steel beam 5 from deflecting along the horizontal extension direction of the sidewall of the steel column 1.

[0048] As shown in Figures 1 and 2, in the steel structure beam-column connection structure provided in this embodiment, at least one upper supporting plate 3 is pre-installed on the steel column 1. During assembly, the upper flange plate 7 of the steel beam 5 is supported by the upper supporting plate 3 pre-installed on at least one side, enabling rapid positioning and installation. Specifically, when two upper supporting plates 3 are pre-installed, the steel beam 5 is lifted until it is aligned with the gap between the two upper supporting plates 3, and then moved downward until the upper flange plate 7 of the steel beam 5 falls on the upper supporting plate 3, and the lower flange plate 8 of the steel beam 5 falls on the lower supporting plate 4, and the assembly is completed; when one upper supporting plate 3 is pre-installed, the steel beam 5 is lifted until the upper flange plate 7 falls on the pre-installed upper supporting plate 3, and the lower flange plate 8 falls on the lower supporting plate 4, and then translated to one side of the web 6 to contact the end face of the pre-installed upper supporting plate 3. After the steel beam 5 is in place, the other upper supporting plate 3 is installed. In addition, as an alternative embodiment, the upper support plate 3 does not need to be pre-installed. After the steel beam 5 is lifted to the lower flange plate 8 and clamped with the lower support plate 4, two upper support plates 3 are installed on both sides of the web 6 of the steel beam 5, so that the upper support plate 3 is clamped with the bottom surface of the upper flange plate 7.

[0049] As shown in Figures 1-3, in the steel structure beam-column connection structure provided in this embodiment, the snap-fit ​​structure 9 includes: a slot and an insert that cooperate with each other; the slot is provided on the support plate 2, and the insert is provided on the bottom surface of the steel beam 5; and / or the slot is provided on the bottom surface of the steel beam 5, and the insert is provided on the support plate 2; during assembly, the insert is inserted into the slot in a vertical direction. The snap-fitting engagement of the slot and the insert achieves a snap-fit ​​connection between the support plate 2 and the steel beam 5, resisting the lateral tension of the steel beam 5, thereby positioning the steel beam 5 and preventing relative movement between the steel beam 5 and the steel column 1.

[0050] As shown in Figures 2 and 3, in the steel structure beam-column connection structure provided in this embodiment, a plurality of first ridges 10 are formed on the support plate 2, and a second ridge 11 is provided on the bottom surface of the steel beam 5 to cooperate with the first ridge 10; during assembly, the first ridge 10 and the second ridge 11 are staggered and interlocked with each other. During assembly, the first ridge 10 on the support plate 2 and the second ridge 11 on the bottom surface of the steel beam 5 are staggered and interlocked with each other, realizing a snap connection between the support plate 2 and the steel beam 5, resisting the lateral tension of the steel beam 5, thereby positioning the steel beam 5 and preventing relative movement between the steel beam 5 and the steel column 1. In addition, as an alternative embodiment, the first ridge 10 and the second ridge 11 can be omitted, and a protrusion is provided on the bottom surface of the steel beam 5 and / or the support plate 2, and a groove is provided on the bottom surface of the support plate 2 and / or the steel beam 5, and the protrusion is embedded in the groove to realize a snap connection.

[0051] As shown in Figures 1-3, the steel structure beam-column connection structure provided in this embodiment further includes: a first support member 12 and a second support member 13 that cooperate with each other, wherein the first support member 12 is arranged on the steel column 1, and the second support member 13 is arranged on the web 6 of the steel beam 5. When the steel beam 5 is assembled with the steel column 1, the first support member 12 is supported on the bottom of the second support member 13. During assembly, the first support member 12 on the steel column 1 blocks and cooperates with the second support member 13 on the web 6 of the steel beam 5, and can resist the vertical torque generated by the weight of the steel beam 5 itself, thereby preventing the steel beam 5 from falling downward. In addition, as an alternative embodiment, the first support member 12 and the second support member 13 can be omitted, and a support plate is provided below the support plate 2, so that the vertical torque generated by the weight of the steel beam 5 itself is resisted by the support plate 2.

[0052] As shown in Figure 2, in the steel structure beam-column connection structure provided in this embodiment, there are two first support members 12 spaced apart, and the space between the two first support members 12 is used to accommodate the web 6 of the steel beam 5. During assembly, the spaced apart first support members 12 are located on both sides of the web 6 of the steel beam 5, respectively, to prevent the steel beam 5 from shifting along the horizontal extension direction of the side wall of the steel column 1. Specifically, two second support members 13 are symmetrically arranged on both sides of the web 6 of the steel beam 5. In addition, as an alternative embodiment, a single first support member 12 can also be provided.

[0053] As shown in Figures 1 and 3, in the steel structure beam-column connection structure provided in this embodiment, a clearance notch 14 is provided on the web 6 of the steel beam 5 at the bottom of the second support member 13 to avoid the first support member 12. During assembly, the clearance notch 14 on the web 6 of the steel beam 5 can avoid the first support member 12, facilitating adjustment of the position of the steel beam 5 along the horizontal extension direction of the side wall of the steel column 1, allowing the steel beam 5 to be quickly installed. Specifically, the steel beam 5 is hoisted to the side of the steel column 1, maintaining the clearance notch 14 on the web 6 of the steel beam 5 at the same elevation as the first support member 12, and then lateral translation of the steel beam 5 until the web 6 is positioned between the two first supports 12, stopping, and then aligning and moving downward. Alternatively, as an alternative embodiment, the clearance notch 14 can be omitted, and the horizontal position of the steel beam 5 is adjusted during hoisting until the web 6 is aligned with the center of the two first supports. The steel beam 5 is then hoisted toward the steel column 1.
