[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0028] Steel structure box columns and H-shaped steel beams are widely used in practical engineering and are respectively used in different structural parts to bear corresponding loads and functions.

[0029] In high-rise buildings, box columns are widely used due to their excellent bending stiffness and torsional stiffness. They can effectively bear various loads, including vertical loads, horizontal loads, etc.

[0030] Box columns are often used as frame columns, especially in situations requiring larger column spacing or higher bearing capacity. Its closed cross-sectional shape makes it perform well in resisting natural disasters such as earthquakes, effectively maintaining the integrity and stability of the structure.

[0031] In large-span structures such as stadiums, exhibition halls, etc., box columns also play an important role. Due to its relatively large cross-sectional area, box columns can provide sufficient support force to ensure the safety and reliability of the structure.

[0032] In industrial plant construction, box columns are also commonly used as load-bearing columns. Since industrial plants usually need to bear the weight of large equipment and production loads, the high load-bearing capacity of box columns makes them an ideal choice.

[0033] In multi-story steel structure frames, H-shaped steel beams are one of the main load-bearing components. They transfer the floor loads to the columns, which then transfer them to the foundation through their connections.

[0034] H-shaped steel beams have a large cross-sectional modulus and moment of inertia, capable of bearing large bending moments and shear forces, so they are widely used in multi-story steel structure frames.

[0035] In bridge engineering, H-shaped steel beams are often used as main beams or part of bridge decks. Since bridges need to bear the weight of vehicles and pedestrians, as well as wind loads and other natural factors, the load-bearing capacity and stability of the beams are required to be high. H-shaped steel beams meet these requirements with their excellent mechanical properties.

[0036] In industrial plants, similar to box columns, H-shaped steel beams play an important role in industrial plant construction. They are not only used for the construction of load-bearing structures, but also often used as crane beams and other special-purpose beams.

[0037] The existing connection joints of steel structure box columns and H-shaped steel beams are achieved by welding, which is very stable. Although this connection method is very firm, when it needs to be disassembled or relocated in actual use, the installation, disassembly and recycling process is very cumbersome and has high loss.

[0038] Please refer to Figures 1-5 A steel structure box column and H-shaped beam connection joint, comprising a box column 100, an H-shaped beam 200, an angle steel one 300, and an angle steel two 400:

[0039] H-beam 200 is located on one side of box column 100. H-beam 200 includes web 201 and flange 202. Flange 202 is fixedly connected to both sides of web 201. There are two angle steels 300, located on both sides of web 201. There are two angle steels 400, located on the outer sides of upper and lower flanges 202. Steel plate 301 is fixedly connected to the inner wall of angle steel 300. A connecting hole 302 is opened on one side wall of angle steel 300. A single-sided high-strength bolt 103 is inserted into the connecting hole 302. An embedded protrusion 303 is fixedly connected to the other side wall of angle steel 300. Steel plate 401 is fixedly connected to the inner wall of angle steel 400. A single-sided high-strength bolt 402 is inserted into one side wall of angle steel 400. A connecting hole 503 is opened on the other side wall of angle steel 400. Steel plate 1 (301) greatly improves the structural stability of angle steel 1 (300), and steel plate 2 (401) greatly improves the structural stability of angle steel 2 (400).

[0040] By using a single-sided high-strength bolt 103 to fix the box column 100 through angle steel 300, and using a second high-strength bolt 208 to fix the H-beam 200 to angle steel 300, the box column 100 and the H-beam 200 are connected. Angle steel 400 can be used to further reinforce the structure between the H-beam 200 and the box column 100, greatly improving the structural stability of the installation between the box column 100 and the H-beam 200. The use of single-sided high-strength bolts 103, 208, 209, and 402 facilitates the assembly and disassembly of the box column 100 and the H-beam 200, improving the efficiency of installation and disassembly, enhancing the stability of the connection node, preventing breakage, and reducing labor and physical costs.

The side of the second embedded protrusion 206 has a second connecting hole 207, and a second high-strength bolt 208 is inserted into the second connecting hole 207. After the second embedded protrusion 206 is inserted into the fourth connecting hole 304, the initial fixation between the angle steel 300 and the H-beam 200 is completed. Then, the second high-strength bolt 208 is passed through the second connecting hole 207 for further fixation, thus distributing the load-bearing capacity of the second high-strength bolt 208 on the connected device.

[0042] For further optimization, please refer to Figure 1 , Figure 2 The side of the box column 100 is provided with a gourd hole 2 102, which matches the model and specifications of the single-sided high-strength bolt 103.
