Abstract: A groin vault ceiling kit comprises a set of four arch-shaped ceiling segments each having a pair of converging diagonal edges oriented at a 45 degree angle relative to a back edge of each of the ceiling segments. Each of the ceiling segments may be comprised of an arch-shaped triangular tip portion which is axially alignable and abuttingly disposed against an arch-shaped semi-circular main portion. A connecting member may be disposed along concave outer surfaces of the tip and main portions for interconection thereof. Each of the tip and main portions may be fabricated of a plurality of laminated members in a pre-formed arch-shape. The groin vault ceiling kit is adapted for installation into a building structure such as via wall studs and ceiling joists where each of the ceiling segments is configured to be secured thereto.

Abstract: In an arcuate roof section including a series of rafters which each define an exposed end of the prescribed height, a device positionable along the exposed ends of the series of rafters to define an arcuate facia. The device comprises at least one facia member having an arcuate inner surface, an arcuate outer surface, a top edge and a bottom edge. The inner surface of the facia member is configured to abut the exposed ends of the rafters such that the outer surface defines the arcuate facia. Additionally, the width between the top edge and the bottom edge of the facia member exceeds the height of the exposed ends. The facia member may be formed from a plurality of laminated wood members or formed from bonded particulate matter. Additionally, the facia member may be formed from a plastic material.

Abstract: An arch for a ceiling structure having a first vertical wall stud and a second vertical wall stud. The arch includes an arcuate center section having opposed ends and an arcuate under surface with a first radius of curvature. The arcuate center section is sized and configured such that the opposed ends thereof abut respective ones of the first and second wall studs. The arch further includes a first and second arcuate side section attached to the center section and respective ones of the first and second vertical wall studs. Each of the first and second side sections has an arcuate under surface with a second radius of curvature less than the first radius of curvature. Accordingly, the first and second side sections create a continuous transition between the under surface of the arcuate center section and respective ones of the first and second vertical wall studs.

Abstract: A domed ceiling structure for attachment to an elevated support. The ceiling structure includes a peripheral frame member which is attachable to the support frame, and a plurality of arcuate support members, each of which has first and second ends, an upper surface, and an under surface. The first ends of the support members are attached to the frame member in a manner wherein the second ends extend to a common area and the under surfaces collectively define a dome shaped support surface to which a layer of finishing material may be applied.

Abstract: A device for forming an arcuate ceiling structure which is positionable between first and second opposed rows of vertical wall studs having at least one horizontal header extending therebetween. The device comprises a first ledger attached to the first row of wall studs and the second ledger attached to the second row of wall studs. At least one arcuate member is provided which has first and second longitudinal ends, an arcuate upper surface and an arcuate undersurface. The length between the first and second ends is such that when the arcuate member is positioned between the first and second ledgers, the first end will abut the first ledger, the second end will abut the second ledger, a portion of the upper surface will abut a header, and the undersurface will form an arcuate support surface to which a sheet of finishing material may be applied.
