Adjustable frame for encasing reinforced concrete beams

摘要

The invention relates to an adjustable frame for encasing reinforced concrete beams or the like, in which the rectangularity of the connection between uprights and girders is achieved in that the girder - or the upright - has, in the region of its lateral sides, lateral projections, the distance of which from one another corresponds to the width of the upright - or of the girder. Uprights and girders are moreover provided with series of holes so that at the point of intersection of the two structural parts a connecting means can be inserted. In a frame thus assembled, the upright bears against the girder and is held in this position by the contact surfaces on the projections.
