FIELD: building industry. SUBSTANCE: multiple mould for manufacture of columns with cantilevers uses a bottom in the form of a bearer frame, on which the moulding plate separated by partitions is installed. The plate has slots and pits for formation of cantilevers, spaced in bottom length and rigidly secured to the frame in locations of the slots. One of the pit walls is made detachable and its cross-section has the shape of a hollow wedge with one vertical side and base positioned at the same level as the moulding plate. The partitions are secured for deflection outside. Secured on the longitudinal boards are movable devices for formation of cantilevers in the form of a frame with hollow longitudinal walls and plate end face and intermediate transverse walls, forming holes whose dimensions in plan and location coincide with those of the pits. The end face boards of the mould can be drawn back. EFFECT: enhanced convenience in use. 3 dwg
