The holes and bolts between the anchorage frames need to accurately correspond, and the connections need to be tightened to avoid axial displacement; an adjustable bolt device should be arranged at the end of the attachment rod near the building, and the adjustment length should not exceed 200mm; When rising to the required anchoring distance, an anchoring device needs to be added, and the anchoring device higher than the tower body must meet the factory regulations.
What are the common problems of tower crane anchoring devices?
1. Some construction parties do not have sufficient tower crane attachment facilities. When the construction building is higher than the height of the tower crane, the corresponding construction requirements cannot be met, and finally, the tensile, torsional, and compressive strength of the anchoring device is reduced.
2. In order to reduce the cost, the construction party did not install adjustable bolts on one side of the struts during construction, but adopted welding methods. If the foundation of the tower crane sinks evenly, the length of the tie rods cannot be adjusted. The adjustment will cause the strut to be bent, its tensile strength will be greatly reduced, and the problem of steel pipe fracture may also occur.
