building structures particularly, mainly, dismountable-assembled, applicable in industrial and civil construction of temporary dismountable-assembled buildings and structures, for instance, exhibition pavilions, covered temporary storages, etc. SUBSTANCE: dismountable-assembled prestressed metal-wood trussed beam includes roof beam made in form of sections, strut frame posts and lagging with tension devices. Posts have box-shaped locks with central holes in which cores with contact surfaces are introduced and directed at acute angle to longitudinal axis of roof beam. End sections of roof beam at level of core axes are made with longitudinal slots and transverse holes. Cores are made with threaded holes. EFFECT: simplified manufacture of dismountable-assembled metal-wood trussed beams, reduced consumption of material due to design features of conjugation units and repeated use of materials. 2 cl, 2 dwg
