[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates, and undergo rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion, and generally require rust removal, galvanizing, or painting, as well as regular maintenance. The development and application of new prefabricated steel structure systems are of great significance to the industrialization of structural engineering.

[0003] The current connection method between steel components requires on-site welding, which greatly affects the construction speed and quality. In addition, the construction procedure is complicated, the installation is time-consuming and labor-intensive, the assembly speed is slow, and the steel component connection node device only has the function of connection, which is single. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides the following technical solution: a quick-assembly multifunctional steel component connection node device, including a square steel column 1, a slot 17 is provided in the middle of the surface of the square steel column 1, a left card plate 5 is provided on one side of the surface of the slot 17, a right card plate 6 is provided on the other side of the surface of the slot 17, a left positioning block 8 is fixedly connected to both sides of the surface of the left card plate 5, a right positioning block 7 is fixedly connected to both ends of the surface of the right card plate 6, an internal hexagon bolt 15 is provided on one side of the right positioning block 7, and the other end of the internal hexagon bolt 15 is threadedly connected to the right positioning block 7 and the left positioning block 8, a first limiting plate 9 is fixedly connected to one end of the surface of the left card plate 5, a second limiting plate 10 is fixedly connected to one end of the surface of the right card plate 6, trapezoidal steel columns 2 are provided on the inner surfaces of the first limiting plate 9 and the second limiting plate 10, and insertion holes 13 are provided inside the trapezoidal steel column 2, the first limiting plate 9 and the second limiting plate 10.

[0023] In this embodiment, the support block 18 supports the connection between the left card plate 5 and the right card plate 6, reducing the pressure on the left card plate 5 and the right card plate 6. The support block 18, the square steel column 1, and the connection between the left card plate 5 and the right card plate 6 form a triangular support force distribution mode, making it more solid and stable.

[0024] In this embodiment, the threaded connection between the first plug-in post 12 and the first threaded block 16 allows workers to quickly assemble the device. At the same time, the trapezoidal steel column 2 can rotate along the surface of the first plug-in post 12, thereby adjusting the angle between the trapezoidal steel column 2 and the square steel column 1. This avoids the connection method at the joint being too simple and makes the device more versatile.

[0025] In this embodiment, the insert block 14 can work with the hexagon socket bolt 15, the support block 18 and the slot 17 to restrict the position of the left card plate 5 and the right card plate 6. The support and restriction from three different directions make the connection between the left card plate 5 and the right card plate 6 more stable, avoid the hexagon socket bolt 15 at the connection point from bearing all the pressure, improve the service life of the hexagon socket bolt 15, and prevent the left card plate 5 and the right card plate 6 from deforming due to long-term use.

[0026] In this embodiment: by adjusting the position between the connecting block 19 and the connecting plate 21, the trapezoidal steel column 2 can be rotated along the first insertion column 12, thereby adjusting the angle between the trapezoidal steel column 2 and the square steel column 1. Then, by passing the second insertion column 20 through the interior of the connecting block 19 and through the positioning holes 22 at different positions, and screwing the second threaded block 23 onto its other end, the adjusted angle can be temporarily fixed, so that the device can adapt to various connection methods at different angles and has more functions.

[0027] In this embodiment, the left card plate 5, right card plate 6, right positioning block 7, left positioning block 8, first limiting plate 9 and second limiting plate 10 are all modularly designed, which facilitates quick assembly and splicing by workers. At the same time, when a part is damaged, it can be quickly replaced, which improves the construction speed and assembly speed, simplifies the assembly process, and makes the construction procedure simpler.

[0028] The working principle and usage process of this utility model are as follows: After the utility model is installed, the left card plate 5 and the right card plate 6 are respectively snapped into the two sides of the surface of the card slot 17. Then, the left card plate 5 and the right card plate 6 are connected by passing through the inside of the right positioning block 7 and the left positioning block 8 with the internal hex bolts 15. Then, one end of the trapezoidal steel column 2 is made to contact the inner surface of the first limiting plate 9 and the second limiting plate 10 to ensure that the positions of the insertion holes 13 of the three are consistent. The first insertion post 12 is passed through the insertion hole 13, and then the first threaded block 16 is screwed on the other end of the first insertion post 12 to assemble it. The connecting plate 21 is inserted into the inside of the connecting block 19. The position of the two is shortened or lengthened according to the connection needs. The angle of the trapezoidal steel column 2 is adjusted through the positioning holes 22 at different positions. Then, the second insertion post 20 is passed through the inside of the connecting block 19 and the positioning hole 22, and the second threaded block 23 is screwed on its other end to complete the splicing.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
