[0002] In the field of building construction, steel columns are important load-bearing structures, and the ease of assembly and stability of their construction are crucial. Traditional steel column assembly methods have many problems.

[0003] Regarding the connection between column bases and columns, existing connection structures are often complex and lack effective positioning and fixing measures. Some column base-to-column connections lack dedicated positioning components, requiring significant time for alignment and adjustment during installation, resulting in low construction efficiency. Some connection structures rely solely on simple welding or bolt connections, which are prone to loosening or deformation under heavy loads, affecting the overall stability and safety of the steel columns. Furthermore, rapid positioning is difficult to achieve during the connection process, making deviations in the connection prone to occur, thus affecting the verticality and stability of the entire building structure.

[0004] Therefore, it is necessary to modify it to effectively avoid problems such as positioning difficulties, loose connections and deformation, and easy deviations during the steel column assembly process, thereby improving the convenience, stability and adaptability of steel column assembly and enhancing the efficiency and quality of building construction.

Second threaded holes that mate with each other are formed above the L-shaped limiting plates and below both sides of the upper column. A second high-strength bolt is threaded inside the second threaded hole above the L-shaped limiting plates. A circular positioning groove that mates with the positioning post is formed in the center of the bottom of the upper column. A top beam fixing groove is rotatably connected to the top of the upper column via a rotating shaft. Positioning structures are provided on the top of both sides of the upper column.

[0007] The column base structure includes a load-bearing plate fixedly connected to the bottom of the trapezoidal block, a counterweight fixedly connected to the bottom of the load-bearing plate, a placement plate fixedly connected to the bottom of the counterweight, a plurality of evenly distributed reinforcing plates fixedly connected to the surface of the counterweight, reinforcing ribs fixedly connected to the top and bottom of the reinforcing plates, and the top and bottom of the reinforcing plates fixedly connected to the bottom of the load-bearing plate and the top of the placement plate, respectively.

Detailed Implementation

[0011] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0012] like Figures 1 to 6As shown, the present invention provides a steel column that is easy to assemble, comprising a column base structure 1, a lower column body 2, and an upper column body 3. A trapezoidal block 4 is fixedly connected to the center of the top of the column base structure 1. A trapezoidal positioning groove 5 that mates with the trapezoidal block 4 is opened at the center of the bottom of the lower column body 2. A U-shaped insert 6 located outside the trapezoidal block 4 is fixedly connected to the top of the column base structure 1. A U-shaped insertion groove 7 that mates with the U-shaped insert 6 is opened at the bottom of the lower column body 2. A limiting frame 8 located outside the U-shaped insert 6 is fixedly connected to the top of the column base structure 1. The limiting frame 8, the U-shaped insert 6, and the bottom of the lower column body 2 are all provided with mutually mating first threaded holes 9, and the first threaded holes 9 located around the limiting frame 8 are threadedly connected inside. The upper column 2 has a first high-strength bolt 10, a circular groove at the center of the top of the lower column 2, and a positioning post 11 is slidably connected inside the circular groove. L-shaped limiting plates 12 are hinged on both sides of the positioning post 11. Square grooves that cooperate with the L-shaped limiting plates 12 are opened on both sides of the upper column 3. Second threaded holes 13 that cooperate with each other are opened above the L-shaped limiting plates 12 and on the lower sides of both sides of the upper column 3. A second high-strength bolt 14 is threaded inside the second threaded hole 13 located above the L-shaped limiting plates 12. A circular positioning groove 15 that cooperates with the positioning post 11 is opened at the center of the bottom of the upper column 3. A top beam fixing groove 16 is rotatably connected to the top of the upper column 3 through a rotating shaft. Positioning structures 17 are provided on the top of both sides of the upper column 3.

[0013] refer to Figure 3 The column base structure 1 includes a load-bearing plate 18 fixedly connected to the bottom of the trapezoidal block 4. A counterweight block 19 is fixedly connected to the bottom of the load-bearing plate 18. A placement plate 20 is fixedly connected to the bottom of the counterweight block 19. Several evenly distributed reinforcing plates 21 are fixedly connected to the surface of the counterweight block 19. Reinforcing ribs 22 are fixedly connected to the upper and lower sides inside the reinforcing plates 21. The top and bottom of the reinforcing plates 21 are fixedly connected to the bottom of the load-bearing plate 18 and the top of the placement plate 20, respectively.

[0014] This embodiment increases the stability and load-bearing capacity of the column base structure 1 by setting up the load-bearing plate 18, counterweight block 19 and placement plate 20, which can better support the weight of the upper structure of the steel column. The design of the reinforcing plate 21 and reinforcing rib 22 further enhances the strength of the column base structure 1, making it less prone to deformation when subjected to greater pressure, ensuring the overall safety and reliability of the steel column, providing a solid foundation for the use of steel columns in different geological conditions and building environments, and helping to improve the adaptability and service life of steel columns.

[0015] refer to Figure 6The positioning structure 17 includes ear plates 23 fixedly connected to both sides of the top of the upper column 3. The surface of the ear plates 23 is provided with a third threaded hole 24 that runs vertically through the top and bottom. The inner thread of the third threaded hole 24 is connected to a third high-strength bolt 25. The top of the third high-strength bolt 25 is fixedly connected to an elastic block 26. The top of the elastic block 26 fits against the bottom of the top beam fixing groove 16.

[0016] This embodiment achieves effective positioning and fixation of the top beam fixing groove 16 by using the ear plate 23, the third threaded hole 24, the third high-strength bolt 25, and the elastic block 26 in combination. The elastic block 26 provides a certain buffer and elasticity when the top beam is connected to the top beam fixing groove 16, reducing stress concentration at the connection and avoiding damage caused by rigid connection. At the same time, the threaded connection of the third high-strength bolt 25 ensures the stability and reliability of the positioning structure 17, making the connection between the top beam and the steel column more secure, further improving the safety and stability of the connection between the steel column and the top beam, and contributing to the stability of the entire building structure.

[0017] refer to Figure 3 Anti-tilting columns 27 are fixedly connected to the front and rear sides of the top of the lower column 2, and reinforcement grooves 28 that cooperate with the anti-tilting columns 27 are opened on the front and rear sides of the bottom of the upper column 3.

[0018] In this embodiment, the anti-tilting column 27 at the top of the lower column 2 cooperates with the reinforcing groove 28 at the bottom of the upper column 3, playing an important anti-tilting role during the column connection process. It can effectively prevent the upper column 3 from tilting during installation or use, ensuring the verticality and stability of the steel column. In building construction, the verticality of the steel column is crucial to the stability of the entire building structure. This design avoids structural deviations caused by column tilting, improves the quality and safety of building construction, and ensures the reliability of the building structure.

[0019] refer to Figure 1 The inner wall of the top beam fixing groove 16 is fixedly connected with a damping pad 29, and the inner surface of the damping pad 29 is provided with anti-slip texture.

[0020] This embodiment increases the friction between the top beam and the top beam fixing groove 16 by setting a damping pad 29 and anti-slip texture on the inner wall of the top beam fixing groove 16. When the top beam is installed in the top beam fixing groove 16, the damping pad 29 can play a buffering role, reducing the collision and wear between the top beam and the fixing groove, and extending the service life of both. The anti-slip texture further prevents the top beam from sliding in the fixing groove, ensuring the stability of the connection between the top beam and the steel column, so that the top beam can be more firmly fixed to the steel column, improving the safety and stability of the entire building structure.

[0021] refer to Figure 1Both the front and rear sides of the top of the lower column 2 are fixedly connected with filler welding pieces 30, and the thickness of the filler welding pieces 30 is the same as the thickness of the L-shaped limiting plate 12.

[0022] In this embodiment, by setting a filler welding piece 30, the gap between the lower column 2 and the upper column 3 can be tightly filled during installation, and then welded together to form a solid structure. This connection method greatly enhances the strength of the connection, enabling it to withstand greater external forces and loads, and effectively avoids loosening or deformation caused by external forces.

[0023] refer to Figure 6 A T-shaped ring 31 is fixedly connected to the bottom of the top beam fixing groove 16, and an annular guide rail 32 that mates with the T-shaped ring 31 is fixedly connected to the top of the upper column 3. The surface of the T-shaped ring 31 is slidably connected to the inner wall of the annular guide rail 32.

[0024] In this embodiment, the T-shaped ring 31 at the bottom of the top beam fixing groove 16 is slidably connected to the annular guide rail 32 at the top of the upper column 3, providing the top beam fixing groove 16 with flexible rotation function. When installing the top beam, the angle of the top beam can be finely adjusted according to actual needs, which improves the adaptability and flexibility of the connection between the steel column and the top beam, enabling the steel column to better adapt to different building structures and construction requirements, facilitating installation and adjustment during the building construction process, and improving the efficiency and quality of building construction.

[0025] refer to Figure 2 A compression spring 33 is fixedly connected to the bottom of the positioning post 11, and the bottom end of the compression spring 33 is fixedly connected to the bottom of the inner wall of the circular groove.

[0026] In this embodiment, by setting a compression spring 33 at the bottom of the positioning column 11, a certain amount of elastic support can be provided when the upper column 3 is installed. When the positioning column 11 is inserted into the circular positioning groove 15, the compression spring 33 can buffer the impact force of the upper column 3, reducing damage to the positioning column 11 and the lower column 2. At the same time, during the use of the steel column, the compression spring 33 can also elastically expand and contract according to the change of load, further improving the stability and reliability of the connection between the upper column 3 and the lower column 2, which helps to improve the overall performance of the steel column.

[0027] First, fix the column base structure 1 in the predetermined position with bolts or pour cement. Align the trapezoidal positioning groove 5 at the bottom of the lower column 2 with the trapezoidal block 4 at the top of the column base structure 1, and align the U-shaped insertion groove 7 with the U-shaped insertion piece 6. After completing the initial positioning, screw the first high-strength bolt 10 into the limiting frame 8, the U-shaped insertion piece 6, and the first threaded holes 9 around the bottom of the lower column 2 to firmly connect the column base structure 1 to the lower column 2. Next, align the circular positioning groove 15 at the bottom of the upper column 3 with the positioning post 11 in the circular groove at the top of the lower column 2, so that the bottom of the upper column 3 is close to the top of the lower column 2, causing the positioning post 11 to slide downwards and its upper end to insert into the circular positioning groove 15, thereby driving the L-shaped limiting plate 12. The upper column 3 is moved inward and inserted into the square grooves on both sides of the upper column 3. Then, the second high-strength bolt 14 is screwed into the second threaded hole 13 to fix the upper column 3 and the lower column 2. Then, the top beam is placed in the top beam fixing groove 16. The top beam fixing groove 16 is positioned and fixed by the ear plate 23 of the positioning structure 17, the third threaded hole 24, the third high-strength bolt 25 and the elastic block 26. The top beam is fixed in the top beam fixing groove 16 by bolts. During the entire installation process, the anti-tilting column 27 and the reinforcing groove 28 are used to prevent the upper column 3 from tilting. The filler welding piece 30 fills and welds the gap between the lower column 2 and the upper column 3. The angle of the top beam can be finely adjusted by the T-ring 31 and the annular guide rail 32 as needed.
