Splice plate for faceted radius grid

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).
