[0002] Steel structure support columns are important vertical load-bearing components in steel structure buildings or facilities. They are usually made of steel, have high strength and good load-bearing performance. Common shapes are round, square, rectangular, etc. Some steel structure support columns need to be installed in strong wind areas, which means that the support columns need to have certain wind resistance.

Compared with circular support columns, rectangular support columns will form obvious airflow separation and vortexes at the corners of the windward side, resulting in large local wind pressure, which in turn causes stress concentration, and further causes local damage or deformation at the corners.

[0022] The working principle and use process of the utility model are as follows: the staff can install the support column 2 in a suitable position according to actual needs, and then the staff can sleeve the left connecting frame 3 and the right adapting frame 31 on the outside of the support column 2, and the staff needs to ensure that the right adapting frame 31 is located on the windward side of the support column 2, and then the staff can fix the support base 1 to a suitable position on the ground by bolts or ground anchors, and then the staff can connect and fix the mounting blocks 34 on the outside of the left connecting frame 3 and the right adapting frame 31 by bolts, so that the left connecting frame 3 and the right adapting frame 31 can continue to be located on the outside of the support column 2 Then, the staff can rotate the threaded rod 14 to make the threaded rod 14 drive the auxiliary block 15 and the adjustment seat 11 to slide horizontally. The adjustment seat 11 will drive the connecting rotating rod 13 to rotate during the movement, so that the inclination angle of the connecting rotating rod 13 changes, thereby changing the vertical height of the supporting seat 12. When the supporting seat 12 is adjusted to a suitable height, the staff can fix the connecting rotating rod 13 to the adjustment seat 11 and the supporting seat 12 respectively by bolts or the like, so that when the support column 2 is subjected to the force of strong wind, the force will be transmitted to the connecting rotating rod 13, and then transmitted to the adjustment seat through the connecting rotating rod 13 11 and the support base 1, so that the support base 1 can stabilize the support column 2. When strong wind blows toward the support column 2, it will first contact the reciprocating buffer block 4, and a plurality of spoiler oblique blocks 41 are slidably arranged on one side of the reciprocating buffer block 4, so that the strong wind will first contact the spoiler oblique block 41, and the strong wind will be guided when it contacts the inclined surface of the spoiler oblique block 41, but because the inclined surfaces of the plurality of spoiler oblique blocks 41 are in different directions, the strong wind will be guided in different ways, so that the strong wind will collide with each other and generate turbulence. Moreover, reset parts such as shrapnel or spring are installed between the plurality of spoiler oblique blocks 41 and the inside of the reciprocating buffer block 4, and the strong wind will be guided when it acts on the spoiler oblique block 41. When the spoiler oblique block 41 is on the surface, the spoiler oblique block 41 will also produce a certain movement, thereby enhancing the disrupting effect of the spoiler oblique block 41 on the strong wind. Since the direction of the strong wind is not horizontal, when the strong wind acts on the surface of the spoiler oblique block 41, it will drive the spoiler oblique block 41 and the reciprocating buffer block 4 to move vertically, and a damping member is installed inside the reciprocating buffer block 4, so that the reciprocating buffer block 4 will have a certain resistance to offset the wind force when sliding vertically, and through the vertical movement of the reciprocating buffer block 4 and the spoiler oblique block 41, the spoiler effect on the strong wind is enhanced, thereby reducing the horizontal force exerted by the strong wind on the support column 2, and improving the wind resistance of the support column 2.
