The connector assembly includes a fitting with a first mounting portion having two opposing surfaces and mounting hole(s) extending between the two surfaces for connecting with a first member. A second mounting portion extends angled with respect to the first mounting portion and has two opposing surfaces and mounting hole(s) extending between the two for connecting with a second member. A joint portion integrally connects the first and second mounting portions. One or more washers each have opposing upper and lower surfaces and at least one hole extending between the two surfaces, each receiving a fastener for attaching the second mounting portion to the second member. The washer lower surface is disposed on the second mounting portion inner surface such that the washer opening is centered about the at least one mounting hole axis. Each washer is joined to the second mounting portion to form an integral assembly.

Described herein is a drywall apparatus including drywall liner. A first gypsum-containing segment is disposed on an internal side of the drywall liner, and a second gypsum-containing segment is disposed on the internal side of the drywall liner such that a groove exists between the first segment and the second segment. The drywall liner connects the first segment to the second segment such that the first segment and the second segment are capable of hinging about a hinge axis parallel to the groove.

A drywall board system for use in conjunction with a baseboard is described. The drywall board system includes a drywall board for securing to framing members and a baseboard backing that receives a baseboard to form a reveal.

A method for the manufacture of a foldable building plate element by providing a flat plate (1), providing of at least one folding groove (2) in the flat plate, providing a folding profile (6), comprising two side wings (7) and an interposed folding portion (8), and fitting the folding groove into the folding profile in such a way, for example by gluing, that the side wings thereof form a strong connection with the two side faces (5) of the folding groove. The side wings are interconnected with each other through a bridging strip (9), which will be removed when the plate is folded. The wings are further provided with connecting means (10) that snap-connect with each other when the side wings are folded towards each other. If desired, a filler strip (11) can be inserted between the side wings.

A method for making a covering is described. The covering includes a first layer made of a flexible material; a second and a third layers made of a preferably rigid material engaged on opposite sides to the first layer. The second and the third layers respectively have a plurality of V-shaped grooves defining respective adjacent rigid and corresponding structural portions. Each rigid structural portion can be oriented with respect to the adjacent rigid structural portion, by folding the first layer so as to model the covering according to three-dimensional configurations and/or a simple or double curvature. The method is preferably performed through a virtual designing of the shape desired to be obtained and a processing of the same for the obtainment of the grooves required to attain such shape.

A drywall system is provided including a first drywall panel and a second drywall panel connected to the first drywall panel via a main hinge. A first drywall flap connected to the first drywall panel via a first hinge, and a second drywall flap connected to the second drywall panel via a second hinge. The first drywall panel, the second drywall panel, the first drywall flap and the second drywall flap can hinge to assume at least one corner configuration in which the first and second flaps lie on a first plane, the first drywall panel lies on a second plane and the second drywall panel lies on a third plane, such that the first plane, the second plane and the third plane are mutually orthogonal. A coating can be provided on an external surface of the framing drywall liner for strengthening the groove which, in embodiments can be polyester strip that extends over portions of the first and second gypsum-containing segments on either side of the of the groove.
