The final first lifting relation function that obtains:
The final second lifting relation function that obtains:
The drop in beam formwork elevation measuring control method of mobile formwork the most according to claim 9, it is characterised in that
According to the first lifting relation function and the second lifting relation function, it is thus achieved that the first mechanical spiral top (5) and the second machinery spiral shell
The height of the most required regulation of rotation top (6),
By adjusting the first mechanical spiral top (5) and the second mechanical spiral top (6), thus realize the absolute altitude essence of drop in beam template (4)
Really control, to meet site operation requirement.
