If Stay Wire Assembly Fititngs is not installed properly, if there is a deviation, it will directly affect the quality of the entire project. Therefore, the deviation of the bolt is a very dangerous thing, so it must be checked and corrected, especially the linkage equipment with a high degree of automation. When deviations occur, they should be dealt with according to the actual conditions of the equipment, and different processing methods should be adopted. Common deviations and processing methods can be roughly divided into the following four types:
1. Center deviation of Stay Wire Assembly Fititngs: When the diameter of Stay Wire Assembly Fititngs is less than 30mm, and the center line is offset within 30mm, you can first bake the bolts red with oxyacetylene, and then use a sledgehammer to bend the bolts (or use a jack to bend the bolts). ), after the correction, the steel plate should be welded firmly to prevent recovery when the bolts are tightened. If the bolt spacing is wrong, you can use oxyacetylene flame to bake it with a sledgehammer, weld a steel plate in the middle to reinforce it, and then fill it to death during grouting. For large bolts (above 30mm in diameter), the bolts should be cut off first, and a steel plate welded in the middle of the bolts. If the bolt strength is not enough, two reinforcement steel plates can be welded on both sides of the bolts. 3 to 4 times smaller than the bolt diameter.
2. The treatment of Stay Wire Assembly Fititngs elevation deviation: When the bolt is too high, the high part must be divided and threaded. When threading, it is necessary to prevent oily substances from dripping onto the concrete foundation to corrode and affect the quality of the foundation. If the bolt is too low (15mm lower than its required height) and cannot be stretched by heating, dig a deep hole around the bolt, cut the bolt at a distance of about 100mm from the bottom of the pit, and weld a new bolt with the elevation required. Meet the requirements, and then reinforce with round steel. The length of the reinforced round bar is generally 4 to 5 times the bolt diameter.
3. Treatment of Stay Wire Assembly Fititngs loose in the foundation: When the Stay Wire Assembly Fititngs are tightened, the bolts may be pulled out. At this time, the bolts should be adjusted to the original position and the foundation around the bolts should be shoveled out enough. Then, weld two U-shaped steel bars vertically and horizontally on the bolts. Finally, the pit is cleaned with water and grouted, and the nuts are tightened after the concrete has solidified to the design strength.
4. How to deal with the deviation of the live Stay Wire Assembly Fititngs: The method of processing the deviation of the live Stay Wire Assembly Fititngs is roughly the same as that of the dead Stay Wire Assembly Fititngs, except that the Stay Wire Assembly Fititngs can be pulled out for processing. If the bolt is too long, it can be cut off on the machine tool and threaded; if the bolt is too short, it can be extended by hot forging; if the position is not consistent, use the bending method to correct it.
