[0016] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0017] This utility model embodiment includes the original structural steel column 1, channel steel 2, corbel top plate 3, corbel web plate 4, channel steel stiffening rib 5, and corbel stiffening rib 6.

[0018] Channel steel 2 is symmetrically arranged on both sides of the original structural steel column 1. The channel steel 2 is arranged laterally; the rear part of the channel steel 2 is welded and fixed to the side of the original structural steel column 1 using a double-sided fillet weld vertical welding method, and the front part of the channel steel 2 protrudes outward. The length of the channel steel 2 is determined according to the process data and the width of the lower flange of the crane beam 7.

[0019] The corbel top plate 3 is welded and fixed to the top of the cantilevered part of the channel steel 2, and the end is surrounded by a fillet weld on site. The corbel top plate 3 also serves as the support plate for the crane beam, and the crane beam 7 is set on the corbel top plate 3.

[0020] The corbel web 4 is located below the corbel top plate 3 and between the channel steels 2 on both sides of the original structural steel column 1. The top of the corbel web 4 is welded to the bottom of the corbel top plate 3 by fillet welds, and the two sides of the corbel web 4 are respectively welded to the two channel steels 2 by fillet welds. The corbel web 4 is located on the plane where the center line of the crane beam 7 is located. The corbel web 4 is manufactured in the factory and transported to the site.

[0021] The channel steel stiffening rib 5 is installed in the channel steel 2. The upper and lower ends of the channel steel stiffening rib 5 are welded and fixed to the upper and lower flanges of the channel steel 2, respectively. The inner side of the channel steel stiffening rib 5 is welded and fixed to the web of the channel steel 2. The channel steel stiffening rib 5 is positioned opposite to the corbel web 4 and is manufactured in the factory.

[0022] The corbel web 4 is symmetrically provided with corbel stiffening ribs 6 on both sides. One side of the corbel stiffening rib 6 is welded and fixed to the corbel web 4, and the top is welded and fixed to the corbel top plate 3. The corbel stiffening rib 6 is located on the surface where the center line of the original structural steel column 1 is located. The corbel web 4 and the corbel stiffening rib 6 combine to form a cross shape.

[0023] The installation method of this utility model embodiment is as follows: The channel steel 2 is symmetrically welded vertically to both sides of the original structural steel column 1 using double-sided fillet welds. The welding is carried out on site, and corresponding measures are taken to reduce the impact of residual stress on the original structural steel column 1. The corbel web 4 and corbel stiffening rib 6 are connected to the corbel top plate 3 by fillet welds. The corbel stiffening rib 6 is fabricated in the factory and transported to the site.
