FIELD: construction.
SUBSTANCE: invention relates to erection of building structures from monolithic reinforced concrete with use of fixed formwork. Non-detachable formwork unit consists of external and internal plates, installed parallel to each other and interconnected by bridges with formation of internal volume for installation of reinforcement and filling with construction filler. Additional tightening device is removable of beams installed horizontally on outer surfaces of plates at distance from bottom of plates, which is from zero to 1/3 of height of plates, and tightened together by threaded elements installed in holes made coaxially in detachable beams and plates, note here that detachable sleeves are installed in holes in plates and have length equal to distance between external surfaces of plates, and sleeves are made from material that is anti-adhesive to cement dough.
EFFECT: technical result is providing invariability of erected structure dimensions due to prevention of plate form plates divergence during filling with concrete mixture.
