FIELD: building, particularly coatings for buildings and building structures.
SUBSTANCE: three-dimensional component comprises convex upper belt and lower belt made as rigid tie member having hinge in tie member center. Upper and lower belts are connected with each other by vertical, longitudinal and transversal links. Lower belt is formed of timber beams adapted to support vertical timber posts connected in pairs by upper and lower cross-beams and intermediate board connection members. The vertical timber posts support upper belt through upper cross-beams. The upper belt is made as vault composed of steel profiled sheet with longitudinal corrugations. The steel profiled sheet is fastened to upper cross-beams.
EFFECT: reduced metal consumption due to provision of joint action of upper and lower belts for bending moment taking.
