FIELD: production of extended reinforced-concrete beams. SUBSTANCE: the tightening heads in the mould stand are installed on the ends of the stand for tightening the reinforcing ropes or wires stretching in the mould cavity, the mould frame comprises long beam members stretching in the longitudinal direction. The beam members have the shape of square-section beams that are encircled by continuously or interruptedly stretching members of the sleeve preventing the lateral bending or breakage of beams as a result of compressive forces arising at tensioning of ropes. EFFECT: creation of thin and inexpensive mould with removed load. 7 cl, 4 dwg
