Beam.
Background technology
It is known：In the work progress of high pier, it is necessary first to carry out frame mould, but successively poured into a mould, in order to save
Construction cost to template, it is necessary to recycle.Therefore, it is necessary to which template is dismantled and then moves on to template after casting complete
Upper strata frame mould again, carry out upper strata cast.
Because high pier is during construction, there is no the strong point on the outside of the template of high pier, therefore lifting can not be realized.In order to
Realize that the dismounting of template and lifting need to set the strong point in the outside of template, so as to realize the dismounting and lifting to template.
In order to realize the dismounting of template, lifting, install again, the method for Bridge High-pier template construction has at present：Sliding formwork is applied
Work, climbing formwork for construction, sliding combination (bridge pier liquid press to turn over molds construction technology) construction is turned over, is climbed and is turned over combination (climbing frame the Turnover Form Construction Technology) and apply
Work, over-form construction, support over-form construction.Sliding formwork, creeping formwork, sliding combination (bridge pier liquid press to turn over molds construction technology) is turned over, is climbed and is turned over combination and (climb
