FIELD: construction.
SUBSTANCE: pre-stressed beam comprises a body made of side longitudinal walls and inner transverse stands, trussed connections and connection reinforcement. The number of stands is accepted as odd. Between the upper ends of the stands and the upper edges of walls, and also between lower ends of stands and lower edges of walls there are clearances for free passage of trussed connections equipped with adjuster bolts and intermediate rings. There are various versions of trussed connections location proposed.
EFFECT: increased bearing capacity of a beam.
