A locking groove 1 8 for inserting the end of the reinforcing T-shaped steel plate 7 is provided on one side of the inner cavity of the placement cavity 2 6, and a locking groove 2 9 for inserting the reinforcing T-shaped steel plate 7 is provided on the right side of the inner cavity of the placement cavity 2 6. A limiting bolt 10 is provided through the left side of the hollow T-shaped frame 3, and the limiting bolt 10 is threadedly connected to the hollow T-shaped frame 3. The end extends to the inner cavity of the placement cavity 5 and rests on the reinforced T-shaped steel plate 7. The surface between the hollow T-shaped frame 3 and the hollow U-shaped frame 4 is sleeved with a U-shaped sleeve 11. The inner side of the U-shaped sleeve 11 is fixedly connected with a stop block 14 extending to the inner cavity of the placement cavity 15 and the placement cavity 2 6. One side of the stop block 14 is in contact with the reinforced T-shaped steel plate 7. The two U-shaped sleeves 11 are fixed by two tension bolts 12. Through the cooperation of the U-shaped sleeve 11 and the tension bolts 12, the U-shaped sleeve 11 is sleeved on the surface of the hollow T-shaped frame 3 and the hollow U-shaped frame 4. The tension bolts 12 are used to penetrate the reinforced T-shaped steel plate 7 and the webs of steel structure 1 and steel structure 2, further reinforcing the connection between steel structure 1 and steel structure 2.

[0020] Working principle: When the present invention is used, the hollow T-shaped frame 3 and the hollow U-shaped frame 4 are welded on the webs of steel structure 1 and steel structure 2 2 respectively, and the steel structure 1 and steel structure 2 2 are aligned and welded. Then the reinforcing T-shaped steel plate 7 is picked up and inserted into the inner cavity of placement cavity 1 5 and placement cavity 2 6, so that the reinforcing T-shaped steel plate 7 fits on the webs of steel structure 1 and steel structure 2 2, and the reinforcing T-shaped steel plate 7 is pushed so that the reinforcing T-shaped steel plate 7 enters the inner cavity of locking groove 1 8 and locking groove 2 9, and then the limiting bolt 10 is screwed. Due to the thread, the limiting bolt 10 moves and rests on the reinforcing T-shaped steel plate 7, limiting the movement of the reinforcing T-shaped steel plate 7. At this time, the reinforcing T-shaped steel plate 7 rests on the webs of steel structure 1 and steel structure 2 2, reinforcing the welds between steel structure 1 and steel structure 2 2, and then the U-shaped sleeve 11 is put on, and the tension bolts 12 are passed through and tightened.

At this time, the reinforced T-shaped steel plate 7 is against the webs of steel structure 1 and steel structure 2, reinforcing the weld between steel structure 1 and steel structure 2, and then putting on the U-shaped sleeve 11, passing the tension bolts 12 and tightening it, so as to achieve the purpose of using an assembled structure to reinforce the weld. In the event of miswelding, the assembled structure can be disassembled and the original welding position can be disassembled without damaging too much steel structure.
