In order to overcome the above problems, a detachable cantilever outrigger fixing device has been developed. Chinese patent ZL201420432898.5 discloses a novel detachable cantilever frame upright rod fixing device, which includes an upright rod hole and a positioning carriage; the structure is characterized in that the vertical rod hole and the upper end of the positioning sliding frame are integrated, two holes at the lower end of the positioning sliding frame are internal thread holes, and the front ends of two locking bolts can be propped against corresponding positions below the I-shaped steel after being screwed into the two internal thread holes at the lower end of the positioning sliding frame, so that the positioning sliding frame and the I-shaped steel are positioned together. The fixing device can be taken down from the I-shaped steel cantilever beam by loosening the locking bolt, but also has the following defects: 1. the cantilever beam is only suitable for I-shaped steel cantilever beams, and is not suitable for cantilever beams of other section steels. Although cantilever beams are mostly made of i-steel, there are also cantilever beams made of other steel sections, such as channel steel. Meanwhile, the fixing device has poor adaptability to cantilever beams of different sizes, so that the application range of the fixing device is relatively small. 2. The location balladeur train can only be emboliaed from the tip of I-steel cantilever beam, and when having the structure that blocks from the end connection of I-steel cantilever beam, this fixed knot constructs unable installation, further influences its application scope. 2. The positioning carriage is somewhat complex in structure and inconvenient to manufacture.

Further, the method comprises the following steps: an upper positioning plate hole is formed in the upper positioning plate, and a lower positioning plate hole is formed in the lower positioning plate; the fastening structure comprises a bolt, a first nut and a second nut, the bolt penetrates through the upper positioning plate hole and the lower positioning plate hole from top to bottom, the first nut is connected with the bolt and compresses the upper positioning plate, and the second nut is connected with the bolt and compresses the lower positioning plate.
Further, the method comprises the following steps: the upper positioning plate hole and the lower positioning plate hole are both long holes arranged along the width direction of the cantilever beam.
Further, the method comprises the following steps: the surfaces of the upper positioning plate and the lower positioning plate, which are contacted with the cantilever beam, are uneven.
The utility model has the advantages that: 1. as shown in fig. 2, the utility model discloses rely on the fixed of tight cantilever beam realization hard pole setting of locating plate and lower locating plate clamp, not only be applicable to the I-steel cantilever beam, other many shaped steel, for example channel-section steel, square steel all are suitable for. Therefore, the utility model has wide application range.
2. The utility model discloses but the split of top board, bottom plate and fastening structure and equipment, the combination of top board, bottom plate and fastening structure need not certainly embolia from the cantilever beam tip, even there is the structure that blocks at the cantilever beam tip, the combination of top board, bottom plate and fastening structure also can be connected with the cantilever beam, makes equally the utility model discloses application scope is wide.
3. Go up the locating plate and be the flat board with locating plate down, fastening structure can comprise conventional fastener, consequently the utility model discloses simple structure, the cost is lower.
4. The upper positioning plate, the lower positioning plate and the fastening structure are conveniently connected with and separated from the cantilever beam, and the upper positioning plate, the lower positioning plate and the fastening structure are conveniently combined and the cantilever beam is conveniently recycled.
