Definitions

  • This invention relates generally to the field drywall construction and more particularly to a system of exterior and interior drywall seams and corners that greatly reduce the amount of time and labour required to finish a modern structure.
  • gypsum drywall board in modern construction is well known.
  • Manufactured drywall sheets are nailed to studs to form interior walls and ceilings. Before these sheets can be painted or textured, the joints must be taped and sealed with joint sealing compound (drywall mud).
  • Flex bead An alternative to taping, especially in seams that do not meet at 90 degrees is the use of a product generally called “flex bead.”
  • Flex bead consists of two thin strips of metal bonded to a two inch paper tape.
  • the first coat procedure is started. Most journeymen only coat one side of the angle at a time. If one tries to coat both sides at the same time, the mud flops over to the other side, and the knife digs a line into the mud on the other side of the angle. Therefore, the following process is usually used: 1) Apply the first coat of mud to one side and wait until it is dry; 2) Apply the first coat of mud to the other side and wait until it is dry; 3) Sand both sides and clean at the crease; 4) Apply the second coat of mud to one side and wait until it is dry; 5) Apply the second coat of mud to the other side and wait until it is dry; 6) Sand and touch up both sides. This process is tedious, and requires considerable time while the respective sides are drying.
  • corner beads are in common use. These include both straight and “bullnose” or rounded versions. These are used on exterior corners at windows and other openings. To use a standard corner bead, it first must be cut from a standard length of 2.44 or 3.05 metres (8 feet or 10 feet). The bead is nailed into position using short nails approximately every 30.5 cm (1 foot). The worker must: 1) keep the bead plumb or level, and 2) keep the bead at the proper angle to prevent slipping too far to one side or the other. If this latter condition occurs, a "shiner”, as it is called in the trade, results. This is where the bead is too far toward one side of the corner making the other side flange hard to coat.
  • the worker must "first coat" the bead. This means to coat it with mud for the first time. This is very labour intensive, and it uses a large amount of mud. After the first coat, the mud is allowed to dry. Drying takes about a day.
  • corner bead for drywall construction is disclosed in US patent specification US-A-5131198 .
  • the corner bead there described has a galvanised steel core strip formed of a central portion, side flanges, and shoulders joining the central portion and side flanges.
  • the front face of the core strip is covered with a paper layer having an outer protective coating thereon overlying the central portion adjoining the shoulders.
  • US-A-3090087 which relates to a metal corner bead of a type used in the 1960's.
  • the corner bead can be fitted to the interior or exterior corner of a building construction and allows finishing of the corner.
  • the corner bead comprises a metal web or ribbon (10) which is glued to a paper cover (13) thus forming a two-layer system.
  • the metal web or ribbon (10) is not of kind which is repeatedly flexible.
  • US-A-5531050 which relates to a metal finishing device used to form a corner between two panels of drywall.
  • the cross-section of the device is that of a triangular web (206) that has a half-tubular centre line (100) that forms a flexible joint about which the piece can be bent.
  • the device is approximately the thickness of a drywall panel with a primed outer surface.
  • the present invention provides a repeatedly flexible drywall trim piece having the features recited in claim 1 hereof.
  • the present invention eliminates most of the intense labour associated with present methods since none of the parts need to be coated with mud or sanded. In addition, the parts form straight, finished lines and angles as soon as they are installed.
  • the present invention relates to corner bead and trim pieces that are simply placed on top of a coat of applied mud at the corner.
  • the corner can be an exterior or interior angle. No nails are required, since the invention pieces stick to the mud.
  • the pieces are paper, plastic, or other suitable material for texturing and painting. They can be tapered on their edges to blend into the adjacent wall when the edges are "killed" with a wide blade knife and a small amount of mud.
  • one of the embodiments of the invention is selected from stock and cut to length if not exactly the right length.
  • a flat coat of mud is applied to both sides of an exterior or interior angle, and the device is placed over the mud and smoothed into place. Since it is preformed, the piece makes a straight line at the required angle. Once, the piece is in place, the edge is "killed” once with a small amount of mud and a wide blade. At that point the corner is complete except for drying. It does not need to be sanded or touched up. When dry, it can be directly textured or painted.
  • Figures 1A and 1B depict an embodiment of a no-coat natural corner.
  • the piece consists of two long flanges 1 of suitable material, preferably paper or other material that will adhere to mud, that form the corner angle.
  • the width of each flange is approximately 178 mm (seven inches); however, this size is not critical, and other sizes can be used from less than 76 mm (3 inches) to wider than 356 mm (14 inches).
  • the piece can be supplied in standard 2.44 or 3.05 metres (8 or 10 foot) lengths, or any other length that is convenient.
  • the thickness of the flange can be from thinner than 0.38 mm (0.015 inches) to greater than 15.9 mm (0.625 inches).
  • the edge of the flange can be tapered to better merge into the wall board when the edge is "killed" While tapering is preferred, it is not necessary to the functioning of the corner piece.
  • a key feature is the ability to "kill" the edge with a small amount of mud and a wide blade knife. In this process the mud is spread into an extremely thin layer over the edge to merge the edge into the surrounding wallboard. This step is preformed only once right after the desired piece is put into place. After this step, the installation of the piece is complete. It is important to note the no nails or other fastening means is used. The pieces are simply stuck on to the wet mud. Of course nails or other fastening means can be used if desired, and a version using nails could be made; however, nails are neither necessary nor desirable since they require time and skill to use, and have the tendency to rust.
  • a strip of plastic, metal, or other material 2 is bonded or glued to the flange to give it rigidity and support.
  • This support member 2 cooperates with the flange and forms a perfect corner seam. The fact that the corner piece is preformed prevents the corner from wandering away from true even when the underlying construction is imperfect.
  • the support member is generally narrower than the flange and can be made from about 5 to 38 cm (2 inches to 15 inches), with 12.7 cm (5 inches) being preferred on a 17.8 cm (7 inch) flange.
  • the support member can be cut flush with the flanges, or it can extend in length beyond the flange at one end and be shorter than the flange at the other end. This allows mating more than one piece when required for longer seams.
  • the angle 4 of the flanges relative to one-another is around 89 degrees. This angle can vary, and different types of pieces can be manufactured for different wall angles. Any angle is possible; however, 89 degrees is the best angle to use for a typical 90 degree corner. This causes the flanges to slightly grip the wall pieces and the wet mud.
  • outside seams can be straight or bullnose of any radius, or any other shape.
  • Bullnose corner beads of the conventional type are popular in residential construction. Bullnose pieces are simply fitted with a bullnose strip on the outside of the corner seam.
  • Figures 2A and 2B depict an embodiment that forms a speciality piece for corners that can be used in conjunction with the natural corner shown in Figure 1A .
  • the piece of Figures 2A and 2B is shaped to be used where two right angle wails join a ceiling at an opening.
  • An outer flat flange 5 fits the higher wall and extends over the opening.
  • a second flat piece 6 runs the vertical wall forming the opening and also along the top of the inside of the opening.
  • the angle between the wall parts 10 and the angle between the top of the opening and the wall 11 should be around 89 degrees for a right angle system; however, parts can be manufactured with any angles for special requirements or special construction angles.
  • the edges 7 and 8 can be tapered to make the "killing" process easier and the final blend into the wall more perfect; however, tapering is optional.
  • the speciality piece shown in Figure 2A and 2B is made from plastic or other suitable material. It can be any length; however it is preferably around 17.8 cm (7 inches) along the short sides, and around 30.5 cm (10 inches) along the longer sides.
  • the exterior seams can be straight or bullnose or other shape.
  • Figures 3A and 3B depict a stub wall or closet opening no-coat trim embodiment. Its length can be a standard 2.44 metres (8 foot) or 3.05 metres (10 foot), or it can be any length. It consists of two long, approximately parallel flanges 12 of similar construction to other embodiments already described, with an inner support member 14. These can be paper or other suitable material, and the support member can be plastic or other material for rigidity. The plastic can be moulded or extruded. The flange thickness is similar to the flanges shown in Figure 1 . In this embodiment, the flanges are coupled to a flat back piece 13. The back piece can contain a spacer if necessary. This spacer is used to eliminate the need to wrap the opening with drywall.
  • the back piece 13 can be different widths (distance between the flanges 12) depending on the construction. In the case of a 89 mm (3 1/2 inch) stud and two 12.7 mm (1/2 inch) sheets of drywall, the back piece 13 would be around 114 mm (4 1/2 inches) wide. In the case of the same stud with two 15.9 mm (5/8 inch) sheets of drywall, the width would be around 121 mm (4 3/4 inches). Different versions of this piece can be made for typical construction situations; specialised versions can be made for any situation.
  • the width of the flanges 12 can be between 7.6 and 38.1 cm (3 inches and 15 inches), with about 15.2 cm (6 inches) being preferred.
  • the thickness of the back piece 13 can be around 9.5 mm (3/8 inch) to form a finished wall. This thickness is not critical to the invention, and many other thicknesses are possible.
  • the piece is first attached with wet finishing mud, and then the edges are "killed" or made to merge into the surrounding drywall with a flat blade tool. The edges can be optionally tapered to merge better.
  • Figures 4A and 4B show a no-coat window trim embodiment.
  • This piece is used to provide a transition from wall drywall to window.
  • This piece is similar to other embodiments with two substantially flat flanges 18 forming an approximate 90 degree angle or other speciality angle of any number of degrees. The actual angle 21 is chosen around 89 degrees of a right angle system for reasons previously explained.
  • a support member 19 is used inside the flanges 18 for rigidity.
  • this piece can be plastic or other rigid material. It is used to give strength and shape to the piece.
  • One of the flanges contains a spacer 20 of the type previously described. This spacer is used to eliminate the need to wrap the opening with drywall.
  • the window piece is constructed so that one flange 18 is from around 7.6 to 17.8 cm (3 to around 7 inches), with around 17.8 cm (7 inches) being typical.
  • the other flange may be shorter to fit a window, with a typical width being from around 7.6 cm (3 inches) to around 15.2 cm (6 inches).
  • the piece can be supplied with several different sized flanges to fit different construction situations. As in other embodiments, the thickness of the flange can be from thinner than 0.38 mm (0.015 inches) to much thicker.
  • the edges of the flanges 18 can be tapered for easy "killing" by the worker.
  • the support member can be from about 12.7 cm (5 inches) on a 17.8 cm (7 inch) flange and can take a similar ratio on a different sized flange.
  • the spacer 20 can be any durable material, and can be around 9,5 mm (3/8 inch) thick. Other sizes are possible to match the needs of the construction.
  • the length of the piece can be a standard 2.4 or 3 metres (8 or 10 feet), or any other length dictated by the construction.
  • FIGS 5A and 5B show a non-coatable L-metal or L-member.
  • This piece is used under window sills, or wherever drywall abruptly ends such as an interface with brick. It is constructed like the previously described embodiments. Even though the piece is being referred to as an L-metal or L-trim, this does not imply that any actual metal is used in its construction.
  • the narrow flange can be from around 12.7 mm (1/2 inch) to around 15.9 mm (5/8 inch) or greater.
  • the wide flange can be from 7.6 cm (3 inches) to over 17.8 cm (7 inches). Again the length of the piece can be the standard 2.4 or 3 metres (8 or 10 feet), or any length dictated by the construction.
  • the support member 26 is very similar to the support members of the previously described embodiments. With a 17.8 cm (7 inch) wide flange, it can be around 12.7 cm (5 inches).
  • the flanges can be paper; however, the preferred method for this piece is to use paper covered plastic for shape and strength. As before, the outside corner can be straight, bullnose or other shape.
  • an alternate embodiment can be made by causing the support member 2 to be constructed as two separate strips with only the flange material 3 along the seam.
  • This embodiment forms a non-coatable flex trim where the worker can adjust the piece for wall corners of any angle.
  • the support member 2 strips should be brought very close together with only a small open region between them. While the distance is not critical, it is important that they not be too far apart since they must support the corner in the folded position.
  • This embodiment can be of an exterior or interior form.
  • the construction can be entirely of paper or other flange material; an exterior piece must be stronger and may be made from cardboard or plastic or other suitable material.
  • This flex trim embodiment can be supplied as standard 2.44 or 3.66 metres (8 feet or 12 feet) lengths, or any other length.
  • the interior version can be supplied on a roll of 7.6 or 30.5 metres (25 feet or 100 feet), or in any other length straight or rolled.
  • Ultra-Flex an embodiment of the present invention that will be called "Ultra-Flex” is seen.
  • This embodiment can be used for interior or exterior corners. Its construction is that of an elongated semi-rigid member with exterior layers of covering and finishing materials.
  • the semi-rigid member can be plastic, metal, or other flexible, but strong material, with high impact plastic such as that used to construct modern cola bottles being preferred.
  • the member can be supplied in 3.05 or 3.66 metres (10 or 12 feet) lengths, or any other convenient length, or it can be supplied on a roll of 30.5 metres (100 feet) or an other convenient length. Running the length of the member can be a groove 32.
  • the elongated semi-rigid member has a first surface 29 that is split into a left part and a right part by the groove 32. It also has a second surface 30 that is continuous (the groove 32 does not penetrate all the way through).
  • the semi-rigid member can be of uniform cross section; however it is preferred to taper it from a maximum thickness near the groove 32 to a minimum thickness near the edges 31.
  • the maximum thickness is between 0.08 and 2.03 mm (3 mil and 80 mil) near the groove or apex and between 0.025 and 0.76 mm (1 mil and 30 mil) at the edges with the thickness at the edges always being less than the thickness near the centre.
  • the preferred maximum thickness is around 1.52 mm (60 mil), and the preferred minimum thickness is around 0.1 to 0.15 mm (4-6 mil). The thickness, of course, can vary from these figures.
  • Figure 7 shows a possible cross section of the "Ultra-flex" piece.
  • the groove 32 is V-shaped, and the overall cross section (without the groove) is triangular. Many other cross sections are possible with this embodiment of the present invention.
  • the semi-rigid member 33 gives the piece strength and support.
  • the groove 32 allows the piece to be repeatably bent to any angle between 0 degrees and 360 degrees by forming a hinge. If the material chosen for the semi-rigid member is high-impact plastic, bending does not fatigue the hinge, and the member can be bent any number of times without breaking. Also, the member in that manner is extremely strong and can resist numerous direct blows to its surface and hinge without any damage.
  • the groove 32 separates the first surface of the piece into a left half and a right half. These two halves do not have to be the same width. In fact, one of the halves can be considerably wider than the other to form an L-trim member or similar type member if desired.
  • the first surface of the semi-rigid member 33 can be covered by two strips of covering material 29 firmly bonded to the semi-rigid member 33. This covering material can be paper similar to that used on drywall, or joint tape paper, or other suitable material to be placed against drywall wallboard.
  • the second surface of the semi-rigid member can be covered by a strip of finishing material 30 also firmly bonded to the semi-rigid member 33. This material can be a finished surface such as cup stock paper that can directly receive paint or texture.
  • It can be any other material that can directly receive paint or texture without the need of sanding or mud.
  • bonded what is meant is any process that firmly attaches the material to the member. Glue could be used, but it is preferable to extrude the entire piece with the semi-rigid member being high impact plastic.
  • the plastic with the groove and both paper layers are formed at once with the plastic being hot melted to the paper layers for a permanent bond.
  • the groove can be made with an extrusion die.
  • the embodiment shown in figures 6 and 7 is only one way of making this type of piece.
  • the piece can be made with any number of grooves to form flexible speciality pieces.
  • it can be constructed with two grooves to form a stub wall piece.
  • the groove can be of other suitable cross sections as required.
  • One great advantage of this embodiment is that the groove allows the piece to be bent to form perfect corners. There is no "snaking" of the corner line, even on uneven walls or construction. Also, since this type of piece can be used at any angle, it can be used anywhere in a modern building.
  • the present invention also comprises a method of installing the various non-coatable, preformed drywall corner pieces of embodiments of the present invention.
  • the worker first applies drywall mud to both flat sides of the corner to be finished.
  • the preformed piece is cut to length and placed in the corner against the wet mud.
  • the piece is positioned for final appearance and pressed into place; then the edges are "killed” by applying a small amount of finishing mud to the edges and smoothing them with a wide blade knife so that they merge into the surrounding drywall. There is no further finishing.
  • the corner is ready for painting or texturing. This represents a considerable savings in time and money over existing methods.
  • variable cross-section of the semi-rigid (support) member is applicable to the numerous embodiments described herein. Specifically, an ability to kill the dry wall trim into the drywall board is significantly enhanced by using a cross-section that varies from a central apex of the drywall trim to the periphery of the dry wall trim. Indeed, killing of the dry wall trim becomes much simpler and is achieved In a straight-forward one-step process.
