To provide a form elevation control method in a slip form construction method capable of facilitating the installation of a device for control when compared with the installation by use of a leveling sensor and elevating a form properly by matching with the direction of extension of a towerlike structure even under the conditions that a support foundation bed is inclination changed.
In this slip form construction method supporting rear surfaces of sliding forms 1a, 1b through a plurality of yokes 2 and elevating each yoke by a climbing mechanism 3, a photoelectric detector 21 is provided in either of a rod 31 for supporting yoke and the yoke 2, and a scale 22 capable of detecting by the photoelectric detector 21 is provided in the other of them to measure a relative displacement amount of the rod 31 for supporting yoke for the yoke 2 by detecting travel scale by the photoelectric detector 21 and control elevation operation by a climbing jack per yoke so that the relative displacement amount becomes a desired set value.
