FIELD: construction.
SUBSTANCE: invention relates to construction, namely to a method for preliminary tension of strut-framed roofing covering. Method is achieved by that, first, the corrugated sheet is laid in an inverted state on the supports, then bent by the value of [f] by weights and in that position the supporting and span tetrahedral rod pyramids are fixed and tightened, then the plate is turned to the design position.
EFFECT: technical result consists in simplification of corrugated sheet pre-stressing.
