DOME Russian patent published in 2015 - IPC E04B1/32 E04B7/08 

FIELD: construction.

SUBSTANCE: dome includes wooden meridional arched ribs made of rods attached with their end faces at an angle to each other, lining attached to the frame and horizontal trusses attached to the meridional ribs. Rods are made of a wooden section including veneer plates and flanges from wooden bars fixed at their longitudinal edges. Rods are fixed with butt strips made of bars fixed on both sides of the veneer plate so that planes of bars, which are located on both sides of the plate and form butt surfaces of the rods, coincide with the plane of its end face. The dome is provided with a vertical load-carrying member that is attached with its upper end to a central supporting member made in the form of a ring, and in downstream sections it is attached to an intermediate floor made of radial beams, one end of which is attached to the corresponding composite meridional rib or supporting member of the dome base, and the other one to the vertical load-carrying member. Neighbouring radial beams are attached to each other by means of additional trusses comprising rings in a plan view, which are concentrically located relative to the vertical load-carrying member.

EFFECT: improvement of structural stiffness.
