The invention relates to building and deals with one-time casing for formation of elements of building structures by monolithic-concrete method. Casing looks like continuous pipe in arbitrary shape of combination of shapes that is obtained by method of layer-by-layer winding strips of paper material on mandrel. As paper material paper or cardboard is used, or composition of cardboard and paper, separate layers of material are fixed with glue. Number of layers makes value enough to achieve thickness of wall able to provide manipulation and operation strength of casing with account of compactness of winding and type of paper material being used, prescribed length of casing, volume needed for mortar filling and pressure formed by it. Outer and inner surfaces of casing are covered with polymer coating. Additionally split element can be mounted to the wall of the casing, for its splitting in length. Advantages: the casing is cheap, it has small weight, does not need use of load-lifting mechanisms, it is simple and convenient in mounting and dismantling, convenient for processing, ecologically safe, completely ready for use. Schematic drawing of invention: - Reinforced frame (needed for strength of bearing column) - concrete column (formed by casing) - Special split strip -Inner coating with polymer film (to prevent effect of moisture from concrete mortar) - Cardboard non-permanent casing with outer coating with polymer film (to prevent effect of external factors on cardboard of casing)
