The hanging basket for bridge construction is a necessary device in bridge construction, and the hanging strip is an important bearing component for hanging a lower steel structure tray, a bottom die, an outer die, an inner sliding beam, an outer sliding beam and the like in the hanging basket. The elevation of the beam body is often required to be adjusted in the construction process so as to meet the elevation requirement of bridge design. The hanging strips are made of thick steel plates with full rows of holes and are supported by bolts, the distance between the hanging strip holes is 120 mm, so that the minimum distance of each adjustment is 120 mm, and no accurate adjustment is available, so that a method of padding steel plates under a support beam after jacking by a jack is often adopted in a construction site, and the steel plates with different thicknesses are used for multiple times of padding so as to achieve more accurate elevation, and the method is not only clumsy and troublesome, time-consuming and labor-consuming, poor in safety, but also low in adjustable accuracy.

Later constructors to avoid this cumbersome process have used a piece of finish-rolled deformed steel bar instead of a sling, since the finish-rolled deformed steel bar can be adjusted using a nut. The problem seemingly solved, but the safety of finish-rolled deformed steel bars is far from that of braces. Firstly, the sectional area of the hanging basket is far smaller than that of the hanging strip, the bearing capacity of the pulling force is limited, and although the hanging basket is made of a better material and is suitable for bearing pure pulling force, the hanging basket is not only static pure straight pulling force in the construction process, but also swinging caused by uneven load and high-altitude wind load and other uncertain factors, and the hanging strip does not have the problems.

How to improve the adjustment precision of the hanging strip and improve the safety of construction is always an existing and urgent matter to solve.
