[0002] Steel structures are an important structural form in the fields of architecture and engineering. Primarily made of steel, they offer advantages such as high strength, light weight, durability, and plasticity. Steel structures are widely used in modern architecture, particularly in projects such as high-rise buildings, bridges, industrial plants, and large exhibition halls. Adjustable steel connection devices are technical devices used to connect steel components, primarily to enhance the flexibility and adaptability of steel structures. These devices typically feature adjustment capabilities, allowing for adjustments to parameters such as connection angle, position, and length during assembly or construction to meet design requirements or specific construction site conditions.

[0003] The connection methods in traditional steel structure connection devices are mostly weld connection, bolt connection or rivet connection. Although the above connection methods can meet general strength requirements and basic connection requirements, they cannot adjust the angle of the steel structure and are difficult to align during installation. Therefore, an adjustable steel structure connection device is proposed to solve the above problems. Utility Model Content

[0033] When using the device, by rotating the connecting frame 7, the rotating rod 4 fixed to the side wall is driven to rotate inside the fixing frame 3, and the installation angle of the I-beam 11 is adjusted. After the angle is adjusted, the fixing bolt 6 is rotated and its lower end is screwed into the fixing hole 5 to fix the adjusted installation angle. Then, the end of the I-beam 11 is inserted into the interior of the connecting frame 7. The movement of the I-beam 11 squeezes the block 9 to make it enter the interior of the fixing frame 8, and squeezes the first spring 10 to make it shrink. When the positioning hole 12 moves to just above the block 9, the first spring 10 loses its extrusion and clamps the block 9 into the positioning hole 12 to fix the I-beam 11, so that each mounting hole 13 corresponds to each mounting bolt 14, and then the mounting bolt 14 is screwed into the mounting hole 13 to complete the quick installation of the I-beam 11 and the connecting frame 7.

[0034] Reference Figure 4 and Figure 5, The side wall of the column 1 is provided with a protective shell 15, which is used for protective beautification. The side wall of the protective shell 15 is provided with a fixing component, which is used to connect the protective shell 15. One side of the protective shell 15 is fixedly connected to a card slot block 18, and the card slot block 18 is used to fix the fixing buckle 25. The fixing component includes a fixing rod 17. A concave hole 16 is opened inside the protective shell 15 on one side. The side wall of the fixing rod 17 is fixedly connected to the side wall of the protective shell 15 on one side. The side wall of the protective shell 15 on one side is fixedly connected to a fixing block 19. The fixing block 19 is internally provided with an insertion rod 20. One side The side wall of the protective shell 15 is fixedly connected to a connecting plate 21, and a transverse groove 22 is opened inside the connecting plate 21. The transverse groove 22 is used for sliding a slide plate 23. The slide plate 23 is slidably connected inside the connecting plate 21. The side wall of the slide plate 23 is rotatably connected to a dial plate 24. The dial plate 24 is used to move a fixed buckle 25. The side wall of the slide plate 23 is rotatably connected to the fixed buckle 25. A second spring 26 is provided inside the connecting plate 21. The second spring 26 is used for rebound reset. One end of the second spring 26 is fixedly connected to the inside of the connecting plate 21, and the other end of the second spring 26 is fixedly connected to the side wall of the slide plate 23.

[0035] To prevent dirt from accumulating on the exposed supporting feet, the protective shell 15 is installed on it. First, the fixing rod 17 fixed on one side of the protective shell 15 is aligned with the recessed hole 16 opened in the other side of the protective shell 15 and inserted to merge them. Then, the dial plate 24 is pulled to move it in the direction of the slot block 18. The dial plate 24 rotates on the side wall of the movable slide plate 23 and slides inside the transverse groove 22. At the same time, the movement of the slide plate 23 stretches the second spring 26. After rotating the fixing buckle 25 to make it tightly engage with the side wall of the slot block 18, the dial plate 24 is then rotated to the inside of the fixed block 19, and the insertion rod 20 is inserted into the hole to lock it, thereby fixing the protective shells 15 on both sides and combining them together.

[0036] Working principle: When using the device, the connecting frame 7 is rotated to rotate the rotating rod 4, and the installation angle of the I-beam 11 is adjusted. Then the fixing bolt 6 is rotated to screw its lower end into the fixing hole 5, and then the I-beam 11 is inserted into the connecting frame 7. The block 9 is squeezed into the fixing frame 8. When the positioning hole 12 moves to the top of the block 9, the first spring 10 loses its extrusion and the block 9 is clamped into the positioning hole 12 to fix the I-beam 11. The mounting hole 13 is aligned with the mounting bolt 14, which facilitates the fixing of the I-beam 11 by the mounting bolt 14.

[0037] When assembling and fixing the protective shell 15, align the fixing rod 17 with the recessed hole 16 and insert it to merge the protective shell 15. Then, move the dial plate 24 toward the card slot block 18. The dial plate 24 drives the slide plate 23 to move, so that the fixing buckle 25 is pressed against the side wall of the card slot block 18. After rotating the dial plate 24 to the inside of the fixing block 19, insert the insertion rod 20 to lock it, thereby fixing the protective shells 15 on both sides.
