Claim:
In a faceted curved main beam in the form of a convex curved beam ( 37 ) or a concave curved beam ( 39 ), that is installed in a ceiling grid of a curved suspended drywall ceiling having curved drywall board ( 70 ) secured to the grid; the grid having cross beams ( 67 ) connected to the faceted curved main beam ( 37 , 39 ); the improvement comprising a splice plate ( 50 ) secured in the faceted curved main beam ( 37 , 39 ) at a bend ( 36 ) that forms a facet of the beam ( 37 , 39 ) and having two integral portions ( 51 , 52 ) connected by a step ( 53 ) with a slot ( 57 ) in one of the portions ( 52 ), wherein a) with the plate ( 50 ) secured in a first position at a bend ( 36 ) in a convex curved beam ( 37 ), the convex curved beam ( 37 ) receives a connector on a cross beam ( 67 ) in the slot ( 57 ), so that a cross beam is positioned where the curved drywall board ( 70 ) contacts the grid, whereby the curved drywall board ( 70 ) is attached directly to the cross beam ( 67 ); and b) with the plate ( 50 ) secured in a second position at a bend ( 36 ) in a concave curved main beam ( 39 ), the concave curved beam ( 39 ) 1) is suspended by a hang wire ( 66 ) secured to a structural ceiling and to the slot ( 57 ) in plate ( 50 ), and 2) receives connector on the cross beam ( 67 ) in a slot ( 72 ) in the concave curved main beam ( 39 ) at a position wherein the curved drywall board ( 70 ) contacts the grid whereby the curved drywall board ( 70 ) is attached directly to the cross beam ( 67 ).
