FIELD: construction industry.

SUBSTANCE: invention relates to the field of construction, in particular to a ribbed dome made of glued trusses. The frame of the ribbed dome includes the lower support element of base 1, meridional arched ribs 2 and upper support element 3. For the manufacture of the meridional ribs and the lower support element of the base, glued wooden arched trusses containing two curved belts fastened together by a connecting grid and having cantilever outlets at both ends were used. Each meridional edge is a glued-wood arch truss, and the lower support element of the base is made in the form of a closed detachable ring of glued-wood arch trusses. The upper support element is made in the form of a frame-ring system. The junctions of the meridional arched ribs with the lower support element of the base and the upper support element are made by means of cantilever releases of the rib belts using grooved and bolted connections.

EFFECT: increase in the spatial rigidity and stability of the dome.
