step three: a first positioning part (61) is installed at a preset position of one end, far away from the steel beam (1), of the horizontal support (2), a second positioning part (62) is installed at the connection position of a lower flange plate (13) and a web plate (12) of the steel beam (1), a second positioning part (62) is installed at the connection position of an upper flange and the web plate (12) of the steel beam (1), and two end parts of the inclined support are adjusted through an adjusting part to be respectively abutted to a first abutting plate and a second abutting plate;
step four: the position of the sleeve (51) on the inclined support is adjusted through an adjusting part (the length of the inclined support is kept unchanged), meanwhile, the length of the first support (71) is adjusted, the end part of the first support (71) is abutted against a second abutting plate at the joint of an upper flange plate (11) and a web plate (12) of the steel beam (1), the inclined support, the first support (71) and the horizontal support (2) form an acute triangle, then, the length of the second support (72) on the inclined support is adjusted, the end part of the second support (72) is vertically abutted against a web plate (12) of the steel beam (1), the end part of the first support (71) is welded with the abutting part of the second abutting plate, a first positioning part (61) is installed at the position of the second support (72) which is vertical to the web plate (12) of the steel beam (1), and the end part of the second support (72) is welded with the first abutting plate of the first positioning part (61), then welding the abutted parts of the two end parts of the inclined support;
step five: installing a trimming plate (4);
step six: and installing a cantilever plate (3).
