Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-3 This utility model provides an embodiment of a steel structure connection device and steel structure component, including a steel column 1, a fixing steel plate 7 installed at the right end of the steel column 1, bolt holes opened at the corresponding positions of the right end of the fixing steel plate 7 and the steel column 1, and mounting bolts 8 installed in the bolt holes. A connecting frame 9 is fixedly connected to the right end of the fixing steel plate 7, a connecting groove 10 is opened inside the connecting frame 9, a steel beam 2 is installed inside the connecting groove 10, a fastening bolt 12 is installed at the connection between the left end of the web of the steel beam 2 and the connecting frame 9, a long bolt 11 is installed at the connection between the left end of the wing plate of the steel beam 2 and the connecting frame 9, an upper protective cover 3 and a lower protective cover 4 are installed at the right end of the steel column 1, the interior of the upper protective cover 3 and the lower protective cover 4 covers the exterior of the connecting frame 9, a retaining ring 6 is fixedly connected to the front end and the rear end of the upper protective cover 3, and an elastic buckle 5 is fixedly connected to the front end and the rear end of the lower protective cover 4, the exterior of the elastic buckle 5 is engaged with the interior of the retaining ring 6.

[0023] Specifically, the fixed steel plate 7 is connected to the steel column 1 via mounting bolts 8, providing basic support for the entire connection device. The connecting frame 9 is fixed to the right end of the fixed steel plate 7, and its internal connecting groove 10 is used to accommodate one end of the steel beam 2. The web and flange of the steel beam 2 are connected to the connecting frame 9 via fastening bolts 12 and long bolts 11, respectively, forming a stable structural connection that can effectively transfer loads and ensure a smooth force transmission path between the steel beam 2 and the steel column 1. By setting the connecting frame 9 and the connecting groove 10, the steel beam 2 can be quickly inserted into the connecting groove 10, thereby improving installation efficiency. The steel beam 2 and steel column 1 are connected and fixed from multiple parts by the installation bolts 8, fastening bolts 12 and long bolts 11, which can effectively bear various loads and ensure the stability and safety of the structure. The upper protective cover 3 and the lower protective cover 4 are attached to the outside of the connecting frame 9 by the snap-fit ​​of the snap ring 6 and the elastic buckle 5, which provides effective protection for the connection parts, reduces the damage of external environmental factors to the connecting parts, reduces the risk of structural performance degradation due to corrosion and rust of the parts, thereby extending the service life of the steel structure and reducing maintenance costs and frequency.

[0024] Reference Figure 1 and Figure 4 The upper and lower sides of the right end of the steel column 1 and the upper and lower ends of the steel beam 2 are all fixedly connected to the fixing frame 13. The middle of the fixing frame 13 is provided with an installation groove. The installation block 14 is slidably connected inside the installation groove. The middle of the installation block 14 is rotatably connected to the connecting plate 15. The opposite end of the connecting plate 15 is fixedly connected to the adjusting screw 16. The opposite end of the adjusting screw 16 is threadedly connected to the adjusting cylinder 17. The outer wall of the adjusting screw 16 is fitted with a corrugated hose 18. The opposite end of the corrugated hose 18 is fixedly connected to the opposite end of the connecting plate 15. The other end of the corrugated hose 18 is rotatably connected to the outer wall of the adjusting cylinder 17.

[0025] Specifically, after the initial connection of the steel beam 2 is completed, the mounting block 14 is installed in the mounting groove within the fixed frame 13. When the adjusting cylinder 17 is rotated, the adjusting screw 16 is threadedly connected to the adjusting cylinder 17, and the adjusting screw 16 is rotatably connected to the mounting block 14 through the connecting plate 15. The adjusting screw 16 will move linearly relative to the adjusting cylinder 17, thereby causing the connecting plate 15 and the mounting block 14 to slide within the mounting groove. This allows for fine adjustment of the position of the steel beam 2 relative to the steel column 1, enabling the compensation of manufacturing and installation errors during the steel structure installation process, improving the installation accuracy and overall performance of the structure. Furthermore, during the use of the steel structure, slight deformation or displacement may occur due to load or environmental factors. This adjustment mechanism allows for timely adjustments to the structure, restoring its stability and extending its service life. The corrugated hose 18 effectively protects key adjusting components such as the adjusting screw 16 and the adjusting cylinder 17, reducing external environmental corrosion and damage, lowering the failure rate of the adjustment mechanism, and improving the reliability of the entire connection device.

[0026] Working principle: During steel structure installation, firstly, the fixing steel plate 7 is installed on the right end of the steel column 1 using mounting bolts 8, ensuring a tight connection between the fixing steel plate 7 and the steel column 1. Then, one end of the steel beam 2 is inserted into the connecting groove 10 of the connecting frame 9. The left end of the web of the steel beam 2 is fixedly connected to the connecting frame 9 using fastening bolts 12, and the left end of the flange of the steel beam 2 is fixedly connected to the connecting frame 9 using long bolts 11. Tightening the bolts initially fixes the steel beam 2 to the steel column 1. Finally, the mounting block 14 is installed on the fixing frame 13. If the position of the steel beam 2 needs to be finely adjusted in the mounting groove, the adjusting cylinder 17 is rotated. The adjusting cylinder 17 will drive the upper and lower adjusting screws 16 to move relative to each other, thereby driving the connecting plate 15 and the mounting block 14 to slide in the mounting groove of the fixed frame 13, so as to achieve precise adjustment of the position of the steel beam 2. Then, the upper protective cover 3 and the lower protective cover 4 are respectively placed on the outside of the connecting frame 9, so that the elastic buckle 5 of the lower protective cover 4 is engaged with the retaining ring 6 of the upper protective cover 3, thus completing the installation of the protective cover and protecting the connection part.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
