[0002] In the process of construction at a building site, it is inevitable to use a tower crane, which can transport items to a high construction site and effectively improve the efficiency of construction. As the construction increases, the height of the tower crane must also increase, so the foundation of the tower crane must be guaranteed to be firm and safe. When fixing the existing tower cranes, most of them are cast on the ground. A relatively large concrete platform, and then the tower crane bracket is fixed to the concrete platform by anchor bolts. However, the actual utilization area of ​​the platform structure cast as a whole is limited, which will cause great waste, and the casting cost is high, which is not conducive to rapid solidification, affecting the use, and is not conducive to the movement of the tower crane. In addition, when fixing, the four corners are mostly supported and fixed by anchor bolts, which makes the side of the tower crane lack of auxiliary support structure and the overall stability is poor. Therefore, when a small tower crane on some construction sites is under construction, it is easy to cause the tower crane to collapse due to insufficient side support. Utility Model Content
