Description

Technical Field

[0002] At present, my country's bridge construction is developing very rapidly, and the bridge structures are also diverse. Due to the limitations of geographical environment and construction conditions, in most cases bridges are constructed using hanging basket suspended pouring.

[0003] As a major component of the hanging basket structure, the steel sling plays the role of bearing and transmitting construction loads. During the construction of the hanging basket, the elevation of the steel sling needs to be adjusted in real time according to the on-site measurement, and the adjustment accuracy is usually at the millimeter level. However, due to the structural characteristics and load-bearing requirements of the steel sling, the locking pin holes on the steel sling need to be arranged according to a certain spacing value. Therefore, the minimum adjustment level of the steel sling elevation adjustment by the locking pin is the locking pin hole spacing value. During the construction process, in order to achieve the purpose of fine-tuning the steel sling, the steel sling is usually adjusted steplessly by padding the steel plate at the steel sling locking pin position. However, the adjustment accuracy of this method still depends on the minimum thickness of a single steel plate, and multiple layers of steel plates need to be stacked to adjust the padding within the locking pin hole spacing range, and the support stability of the steel sling locking pin cannot be guaranteed.
