Detailed Description
In order to make the present invention clearer, the following description is made with reference to the accompanying drawings.
As shown in fig. 1-5, the present invention is composed of an H-shaped steel beam 1, a circular steel pipe column 2, a hoop-type external reinforcing ring 34 and a reinforcing rib 5.
The hoop type outer reinforcing ring 34 is formed by performing full welding around the outer surfaces of the circular steel tube hoop 3 and the outer reinforcing ring 4. The hoop-type outer reinforcing ring 34 can be directly manufactured by steel structure companies without welding on site, so that the quality of welding seams is reliable. In a construction site, only two hoop type external reinforcing rings 34 are sleeved in corresponding positions of the upper side and the lower side of the round steel pipe column 2 respectively, and one circle of the round steel pipe column 2 is completely welded.
The H-shaped steel beam 1 is directly inserted between the upper and lower hoop-type external reinforcing rings 34 and is in contact with the wall of the circular steel tube column 2, and then the H-shaped steel beam 1 is welded and fixed with the circular steel tube column 2 and the ring plate contact part on the inner side of the hoop-type external reinforcing ring 34.
The stiffening ribs 5 are formed by arranging the stiffening ribs 5 in the web plate of the H-shaped steel beam 1 at the overlapped part of the H-shaped steel beam 1 and the hoop type external reinforcing ring 34 and welding and fixing after the H-shaped steel beam 1, the circular steel pipe column 2 and the hoop type external reinforcing ring 34 are welded and reinforced.
