FIELD: construction.SUBSTANCE: pre-fabricated panel comprises a set of bars connected to each other by means of a flexible element stretching via through holes, and its ends are fixed on the extreme bars of the panel. The panel is equipped with a facility for tightening of the flexible element arranged in one of the extreme bars of the panel. Contacting surfaces of adjacent bars may be arranged both as flat and profiled. Between at least two adjacent bars there might be two flat rigid sheets installed, being arranged at both sides from the flexible element, at the same time on bars that contact with them there are slots, where edges of the specified sheets enter. Specified sheets may be made of any material having sufficient stiffness, for instance, of veneer, plastic or glass.EFFECT: increased stiffness of a panel and liquidation of slots and gaps between bars that arise with time.23 cl, 15 dwg |
