[0011] The beneficial effects of this utility model are as follows: Through the operation and cooperation of the front-to-back adjustment component and the left-to-right adjustment component, this utility model can adjust the position of the second connecting ear plate in the front-to-back and left-to-right directions and lock the position of the second connecting ear plate. This allows the connecting hole on the second connecting ear plate to be aligned with the connecting hole on the first connecting ear plate at the bottom of the main steel beam, facilitating the insertion of the connecting pin. By hinged to the two ear plates, the position of the ear plate on the wind-resistant column can be adjusted to accommodate slight deviations, ensuring installation efficiency. This solves the problem that the main structure of the steel beam usually has ear plates reserved for connection with the wind-resistant column.

[0017] Figure 1-4This invention illustrates a top connection structure for a wind-resistant column according to an embodiment of the present invention. It includes a connecting steel plate 2 installed on the top of a square tube wind-resistant column 1 and a rectangular tube 4 welded below a main steel beam 3. A first connecting lug 5 is provided below the rectangular tube 4. A connecting steel plate is positioned between the rectangular tube 4 and the first connecting lug 5. The top of the connecting steel plate is welded to the rectangular tube 4, and the bottom of the connecting steel plate is welded to the first connecting lug 5. Three reinforcing ribs are welded to the connecting steel plate on both the front and rear sides of the first connecting lug 5. A second connecting lug 6 is provided on the top of the connecting steel plate 2. A connecting pin 7 passes through both the first connecting lug 5 and the second connecting lug 6. A front-to-back adjustment assembly 8 is provided between the connecting steel plate 2 and the square tube wind-resistant column 1. The front-to-back adjustment assembly 8 includes an L-shaped cavity 81 formed on the connecting steel plate 2. The inner wall of the L-shaped cavity 81 is fitted against the surface of the square tube wind-resistant column 1, and two long screws are welded to the inner wall of the L-shaped cavity 81. The top of the side of the square tube wind-resistant column 1 has two long adjustment slots 83 through which the long screw rods 82 can pass and move. The surface of the two long screw rods 82 is fitted with limiting shims 84 that abut against the surface of the square tube wind-resistant column 1. The surface of the long screw rods 82 is threaded with check nuts 85 that abut against the limiting shims 84. The top of the square tube wind-resistant column 1 is welded with an upper cover plate 10. The top of the inner cavity of the L-shaped cavity 81 is attached to the top of the upper cover plate 10. The side of the connecting steel plate 2 is welded with four reinforcing plates 11. The two reinforcing plates 11 at the bottom are welded to the square tube wind-resistant column 1, and the two reinforcing plates 11 at the top are welded to the upper cover plate 10. The setting of the reinforcing plates 11 can increase the connection strength between the connecting steel plate 2 and the square tube wind-resistant column 1, effectively reduce the probability of breakage at the connection between the square tube wind-resistant column 1 and the connecting steel plate 2, and increase the firmness of the connection between the connecting steel plate 2 and the square tube wind-resistant column 1. A left-right adjustment component 9 is provided between the connecting steel plate 2 and the second docking ear plate 6. The left-right adjustment component 9 includes a T-shaped long limiting groove 91 opened on the top of the connecting steel plate 2. A T-shaped long limiting strip 92 that slides in the inner cavity of the T-shaped long limiting groove 91 is fixedly connected to the bottom of the second docking ear plate 6. Both ends of the T-shaped long limiting strip 92 are fixedly connected to a fully threaded screw 93 extending to the outside of the connecting steel plate 2. The surface of the fully threaded screw 93 is threaded with two fastening nuts 94. The inner fastening nut 94 abuts against the connecting steel plate 2, and the outer fastening nut 94 abuts against the inner fastening nut 94.
[0018] In use, bolts are pre-embedded in the ground to install the square tube wind-resistant column 1. The first connecting lug 5 below the main steel beam 3 is pre-installed. The long screw rod 82 is moved in the inner cavity of the long adjusting groove 83 until the second connecting lug 6 on the connecting steel plate 2 is in contact with the first connecting lug 5. Then, the check nut 85 is tightened so that the limiting washer 84 is in contact with the surface of the square tube wind-resistant column 1, thus achieving the pre-fixation of the connecting steel plate 2. Next, the connecting steel plate 2 is welded to the position where it contacts the square tube wind-resistant column 1 and the upper cover plate 10. Then, the second connecting lug 6 is moved laterally so that the mounting hole on the second connecting lug 6 is aligned with the connecting lug 5. Align the mounting holes on ear plate 1 5, and install the docking pin 7 on docking ear plate 2 6 and docking ear plate 1 5. During the movement of docking ear plate 2 6, it will drive the T-shaped long limiting strip 92 to slide in the inner cavity of the T-shaped long limiting groove 91. After the docking pin 7 is installed, operate the fastening nuts 94 on both sides until the inner fastening nut 94 abuts against the connecting steel plate 2 and the outer fastening nut 94 abuts against the inner fastening nut 94, thereby locking the position of docking ear plate 2 6 and realizing adjustable installation. This allows the position of the ear plate on the wind-resistant column to be adjusted to accommodate slight deviations and ensure installation efficiency.
[0019] In summary, the top connection structure of this wind-resistant column, through the operation and coordination of the front-to-back adjustment component 8 and the left-to-right adjustment component 9, can adjust the position of the second connecting ear plate 6 in all directions and lock the position of the second connecting ear plate 6. This allows the connecting holes on the second connecting ear plate 6 to align with the connecting holes on the first connecting ear plate 5 at the bottom of the main steel beam 3, facilitating the insertion of the connecting pin 7. By hinged together, the position of the ear plate on the wind-resistant column can be adjusted to accommodate slight deviations, ensuring installation efficiency. This solves the problem that the main structure of the steel beam usually has ear plates pre-installed for connection with the wind-resistant column. Since the wind-resistant column needs to be installed with bolts embedded in the ground, the position of the wind-resistant column is fixed. The top of the wind-resistant column is also welded with an ear plate for the installation of the ear plate on the main structure of the steel beam. There may be slight deviations in the installation holes on the two ear plates, which increases the difficulty of their connection.
[0020] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
