Description

Technical Field

[0002] During the construction of high pier columns, it is easy for the central axis to be in an "S" shape. The real reason is that there are many sections. When the pier column is relatively high, it is difficult to ensure the quality of the formwork, which adds difficulties to the construction of the entire pier column. At the same time, difficulties may also be encountered during construction, such as vibration, formwork installation, or other factors, which can easily cause the deviation of the central axis of the steel formwork, making it difficult for the construction of the pier column to meet the construction standards. It is difficult to operate at high altitudes during the construction of high pier columns. The climbing form is usually 4 - 6 meters per form, but it is very difficult for workers to erect vertical steel bars and control the spacing and protective layer of the steel bars while standing on the base form. If a springboard is set up in the air for standing, the risk factor is high, the operation is difficult, and accidents are likely to occur. Content of the Utility Model
