<p>The formwork for reinforced site concrete columns comprises form panels at an angle to each other, and under-support structures with frames distributed along the form's height. These frames, and further under-support structure units, are comprised in an inflexible vertically alignable tower. Here the support structure units for one of the form panels are mounted vertically to the latter's plane; they can be aligned onto a given column cross-section. The support structure units for an adjacent form panel for another column cross-section setting, are detachably mounted, and those for the other form panels are immovably fixed.</p> |
