FIELD: construction engineering; construction of spatial and flat coverings and ceilings. SUBSTANCE: beam is used in construction of composite-section wood beams ensuring tight joint between members so as to make it work as integral part. Joining members are essentially metal rods tilted through angle 
ranging between 30 and 40 deg, and spaced apart through distance s which is within range h ≥ s ≥ 10d, where h is height of beam section, d is diameter of rods; the latter are driven in lower member of beam through depth l ≥ 20d. EFFECT: enhanced strength of joint. 3 dwg
