Climbing forms for stepwise erection of concrete walls have a platform which is supported by a frame having elongated carriers extending at right angles to the outer side of the wall to be erected and being removably suspended on anchors which are embedded in the wall. The platform supports a pair of parallel guide rails for a form member which carries the boarding of the climbing forms. The rails guide the carriages of the form member so that the boarding can be moved between an advanced position in which it is adjacent to the cavity into which concrete is to be poured and a retracted position in which the wall and the boarding define a passageway which is accessible to workmen on the platform so that the workmen can clean and/or otherwise treat that side of the boarding which faces the wall. The guide rails are mounted in such a way that the platform need not be provided with uncovered slots, gaps, cutouts or other types of openings which would endanger the occupants of the platform or would permit objects to drop from the platform and thus endanger the persons or equipment below the climbing forms.
