A mould for casting in situ pillars, columns, posts and like vertical objects from preferably reinforced concrete, wherein the mould is produced from one or more sheets (2) of corrugated paperboard or some other type of paperboard, plastic, or a composite material which includes at least one of the materials, and wherein the sheet is folded to the shape of a vertical tube (1) of polygonal horizontal cross-section, the tube being reinforced externally by a plurality of circumferentially extending reinforcement collars (11, 11'). The reinforcement collars include a horizontal frame (12, 12') or brim which embraces the tube (1), and a vertical part (13, 14; 13', 14') which extends along at least one side (4A, 4B) of the tube in abutment with said side and extends up to an adjacent reinforcement collar with which it is connected, wherein said part functions to reinforce said side and to form spacer means between the reinforcement collars at the same time. |
