Workplaces have been installed after the completion of the plane formwork, not to do temporary stacking and operating platform to ensure the stability of the stent to prevent the planeplastic formwork elevation and flat deviation.
3,The wall template removed when the first demolition of bracing, with a crowbar gently pry the template, so that the plastic formwork and concrete from, not too much force, especially the yin and yang angle and hole template. To avoid deformation of the template.
