[0001] This application relates to the technical field of steel structure components, and specifically relates to a high-strength steel structure component. Background Art
[0002] Steel structure engineering is a structure mainly made of steel, which is one of the main building structure types. The characteristics of steel are high strength, light self-weight, good overall rigidity, and strong deformation ability. Therefore, it is particularly suitable for building large-span, ultra-high, and super-heavy buildings. As a key component of the steel structure, the steel structure connector connects the steel beam and the steel column into a whole, and can effectively transmit external loads such as gravity and wind load. The performance of the connector will directly affect the overall behavior of the frame structure under the action of the load.
[0003] Most of the connection structure parts between traditional steel beams and steel columns are simple, relying solely on the cooperation of screws and nuts for fixation. Although a large number of screws and nuts are used during the fixation process, they are easily damaged by tensile stress, resulting in weak stability of the connection structure. Therefore, this application proposes a high-strength steel structure component. Utility Model Content
[0004] The purpose of this application is to provide a high-strength steel structure component to solve the problem that the existing steel structure connector has a simple structure and its connection points are easily damaged by tensile stress.

On both sides of the middle plate of the inner wall of one side wing plate of the I-beam column, first connecting plates are provided. The two first connecting plates and the mounting plate are fixed by the cooperation of a first screw and a first nut. Two vertical plates are symmetrically provided on the mounting plate. The middle plate of the I-beam crossbeam is movably inserted between the two vertical plates. The upper and lower wing plates of the I-beam crossbeam are respectively lapped with the upper and lower ends of the vertical plates. The two vertical plates and the middle plate of the I-beam crossbeam are fixed by the cooperation of a second screw and a second nut.
[0008] Further, cross plates connected to the mounting plate are constructed at both ends of the vertical plate, and the two cross plates are respectively lapped with the upper and lower wing plates of the I-beam crossbeam.
[0009] Further, the two cross plates are respectively fixed to the upper and lower wing plates of the I-beam crossbeam by the cooperation of a third screw and a third nut.
[0010] Further, a support plate is connected between the ends of the two cross plates far from the mounting plate and the vertical plate.

Detailed Embodiments
[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application.
[0023] As Figures 1-4 shown, a high-strength steel structure member proposed in an embodiment of this application includes an I-beam column 1 and an I-beam crossbeam 2, and further includes:
[0024] A connecting member 3, including a mounting plate 301 provided on the outer wall of one flange of the I-beam column 1. On both sides of the middle plate and on the inner wall of one flange of the I-beam column 1, first connecting plates 302 are provided. The two first connecting plates 302 and the mounting plate 301 are fixed through the cooperation of a first screw 303 and a first nut 304. Preferably, corresponding mounting holes are respectively drilled through the I-beam column 1 and the mounting plate 301. The first screw 303 is a single-headed screw, one end of which is fixed on the first connecting plate 302, and the other end passes through the I-beam column 1 and the mounting plate 301 through the mounting hole and is fixed to the mounting plate 301, the first connecting plate 302, and the I-beam column 1 through cooperation with the first nut 304. The first connecting plate 302 and the mounting plate 301 are respectively located on the inner and outer sides of the flange of the I-beam column 1, so that the two sides clamp the flange, and their contact areas with the flange are large, making the mounting plate 301 more stable when fixed on the I-beam column 1, the stress-bearing capacity of the mounting plate 301 is stronger, and two vertical plates 305 are symmetrically provided on the mounting plate 301. The middle plate of the I-beam crossbeam 2 is movably inserted between the two vertical plates 305. The upper and lower flanges of the I-beam crossbeam 2 are respectively lapped with the upper and lower ends of the vertical plates 305. The two vertical plates 305 and the middle plate of the I-beam crossbeam 2 are fixed through the cooperation of a second screw 306 and a second nut 307. Preferably, the second screw 306 is a double-headed threaded rod, and the number of second nuts 307 is two and they are respectively thread-sleeved on both ends of the second screw 306. Corresponding mounting holes are respectively drilled through the vertical plates 305 and the middle plate of the I-beam crossbeam 2. When installing the I-beam crossbeam 2, the middle plate of the I-beam crossbeam 2 is movably inserted between the two vertical plates 305, then the second screw 306 is movably inserted through the corresponding mounting hole, and then the second nut 307 is thread-sleeved, so as to connect and fix the I-beam crossbeam 2 and the vertical plates 305. Since the upper and lower ends of the vertical plates 305 are respectively lapped with the upper and lower flanges of the I-beam crossbeam 2, therefore, the two vertical plates 305 will play a role in supporting the I-beam crossbeam 2, sharing the connection stress borne by the second screw 306 and the second nut 307, thereby strengthening the connection strength between the I-beam column 1 and the I-beam crossbeam 2 and improving the load-bearing performance of the I-beam crossbeam 2.
[0025] As Figure 3 and Figure 4As shown, in some embodiments, cross plates 4 are constructed at both ends of the vertical plate 305 and are connected to the mounting plate 301. The two cross plates 4 are respectively lapped with the upper and lower flange plates of the I-beam cross beam 2. By providing cross plates 4 at both ends of the vertical plate 305 that are lapped with the flange plates of the I-beam cross beam 2 and the cross plates 4 are connected to the mounting plate 301, it not only increases the contact area between the flange plates of the I-beam cross beam 2 and the vertical plate 305, but also improves the load-bearing performance of the vertical plate 305, thereby further enhancing the strength of the connection point between the I-beam column 1 and the I-beam cross beam 2.
[0026] As Figure 3 and Figure 4 shown, in some embodiments, both cross plates 4 are respectively fixed to the upper and lower flange plates of the I-beam cross beam 2 through the cooperation of the third screw 5 and the third nut 6. By the cooperation of the third screw 5 and the third nut 6, the cross plates 4 are connected and fixed to the flange plates of the I-beam cross beam 2, further improving the connectivity between the I-beam cross beam 2 and the cross plates 4, thereby enhancing the strength of the connection point between the I-beam column 1 and the I-beam cross beam 2.
[0027] As Figure 3 and Figure 4 shown, in some embodiments, a support plate 7 is connected between the ends of the two cross plates 4 that are away from the mounting plate 301 and the vertical plate 305. By providing the support plate 7, it is used to connect the two cross plates 4, improve the load-bearing performance of the two cross plates 4, and thereby enhance the supporting performance for the I-beam cross beam 2.
[0028] As Figure 3 and Figure 4 shown, in some embodiments, a first reinforcing plate 8 is connected between the opposite sides of the two cross plates 4 and the mounting plate 301. By providing the first reinforcing plate 8, the first reinforcing plate 8 located below supports the cross plate 4 located below, and the first reinforcing plate 8 located above pulls the cross plate 4 located above, thereby enhancing the supporting performance of the two cross plates 4 for the I-beam cross beam 2.
[0029] As Figure 3 and Figure 4 shown, in some embodiments, a second reinforcing plate 9 is connected between the opposite sides of the two vertical plates 305 and the mounting plate 301. The second reinforcing plate 9 is fixedly connected to the first reinforcing plate 8. By providing the second reinforcing plate 9, it is not only used to strengthen the connection strength between the vertical plate 305 and the mounting plate 301, but also used to improve the connection strength of the first reinforcing plate 8 to the two cross plates 4, thereby further enhancing the connection strength between the I-beam column 1 and the I-beam cross beam 2.
[0030] As Figure 2 and Figure 3As shown, in some embodiments, second connecting plates 10 are provided on both of the two first connecting plates 302. The two second connecting plates 10 are fixed to the middle plate of the I-beam column 1 through the cooperation of a fourth screw 11 and a fourth nut 12. By providing the second connecting plates 10 and fixing them to the middle plate of the I-beam column 1 through the cooperation of the fourth screw 11 and the fourth nut 12, not only can the mounting plate 301 be fixed by means of the flange of the I-beam column 1, but also the middle plate of the I-beam column 1 can be used for enhanced fixation, further ensuring the stability of the mounting plate 301 after being fixed to the I-beam column 1, thereby ensuring the stability of the I-beam column 1 and the I-beam cross beam 2 after connection.
[0031] As Figure 2 shown, in some embodiments, a third reinforcing plate 13 is connected between the first connecting plate 302 and the second connecting plate 10. By providing the third reinforcing plate 13, it is used to improve the strength of the first connecting plate 302 and the second connecting plate 10, so as to provide sufficient fixing stability for the mounting plate 301.
