A plastic corner device for installing drywall to form an inside corner. The corner device has a large corner with a smaller corner facing it to form a right parallelepiped, whose sides equal in length the thickness of the drywall panels. The corner device and/or the panels have adhesive applied to them, and the edges of the panels abut the smaller corner to form the inside corner. Adhesive is then applied to the rearward surfaces, and the assembly of the corner device and the panels is adhered to a building structure.

1. A corner device for connecting a pair of drywall panels having a predetermined thickness at an inside corner of a building structure to form a drywall inside corner, said corner device comprising:a first large corner composed of a pair of relatively wide walls connected at a juncture at right angles to each other and facing in one direction, said first large corner forming an inside corner corresponding to the inside corner of said building structure;a second small corner composed of a pair of relatively narrow walls connected to each other at a juncture at right angles to each other and facing said first large corner in a direction opposite the one direction of said first large corner;said second small corner joined to a portion of said first large corner to form a cubicle parallelepiped with outwardly extending exterior sides, said parallelepiped having a predetermined width equal to the thickness of the drywall and including said inside corner of said first large corner; excess portions of said relatively wide walls of said first large corner extending beyond said cubicle parallelepiped;a pair of drywall panels being seatable on said excess portions of said first large corner with the respective edges of the drywall panels engaging said relatively narrow walls of said second small corner to form a drywall inside corner. 2. A corner device according to claim 1 wherein the thickness of the drywall panel is 0.5 inch, and the predetermined width of said cubicle parallelepiped is 0.5 inch. 3. A corner device according to claim 1 wherein said exterior sides of said cubicle parallelepiped are receptive to adhesive for adhering the edges of the drywall panel to said exterior sides. 4. A corner device according to claim 1 wherein said pair of relatively wide walls of said first large corner has a pair of rearwardly facing sides for engaging surfaces of the building structure, said rearwardly facing sides being receptive to adhesive for adhering said corner device to the structure. 5. A corner device according to claim 1 wherein said pair of relatively wide sides of said first large corner extending beyond said cubicle parallelepiped have forwardly facing sides receptive to adhesive to adhere the drywall panels to the corner device. 6. A corner device according to claim 1 wherein said device is made from a hard plastic. 7. A corner device according to claim 6 wherein said plastic is polyethylene. 8. A corner device according to claim 1 wherein said first large corner and said second small corner are an integral unit. 9. A corner device for connecting a pair of panels to form an inside corner for attachment to supporting pieces defining the support for the inside corner, the inside corner having the panels meeting at a linear junction, said corner device comprising:a corner composed of first and second walls intersecting transversely at a linear intersection, said corner being placeable to the place where the inside corner is to be formed with said linear intersection being parallel to and spaced from the juncture of the inside corner, the edges of the pair of panels engaging said first and second walls to form the inside corner. 10. A process for forming an inside corner on supporting structure from a pair of panels of drywall, the drywall having forward and rearward surfaces, using a corner device composed of a first large corner having a pair of relatively wide walls connected at right angles at a juncture and facing in one direction, and of a second small corner composed of a pair of relatively narrow walls connected to each other joined to the first large corner to form a cubicle parallelepiped with outwardly extending sides having forwardly and rearwardly disposed surfaces, said process comprising:applying adhesive to at least one of the edges of the panel where the corner is being formed and the exterior narrow walls of the second small corner;applying adhesive to at least one of the forwardly disposed surfaces of the outwa rdly extending sides of the corner device and the rearward surface of the panel;pressing the panels of drywall against exterior narrow walls of the second small corner and the outwardly extending sides of the corner device to adhere the panels to the corner device;applying adhesive to at least one of the support structures, and both the rearwardly disposed surfaces of the corner device and the rearward surfaces of the panels; andpressing the rearward surfaces of the combined panels and the rearwardly disposed surfaces of the corner device against the supporting structure to form the inside corner on the supporting structure. 11. A corner device for connecting a pair of drywall panels having a predetermined thickness at an inside corner of a structure, said corner device comprising:a pair of relatively planar wider walls disposed in planes intersecting at a transverse angle to each other along a first line;a pair of relatively planar narrow walls disposed in planes intersecting at a transverse angle identical to the angle of intersection of the planes of said wide planar walls along a second line parallel to the first line and forming a small corner;said wide planar walls respectively intersecting said narrow planar walls and terminating at the respective lines of intersection, said lines of intersection being parallel to said first and second lines;said planar narrow walls each having a dimension perpendicular to said second line and to the respective lines of intersection, said dimension being no greater than the predetermined thickness of said drywall panels;said corner device being attachable to the walls defining the inside corner of the structure, said relatively wide planar walls being attachable to the structure with said small corner facing the inside corner of the structure, and said drywall panels being respectively attachable to relatively wide walls and their edges abutting the respective narrow planar walls to form an inside drywall corner on the inside corner of the structure.
