  "abstract": "An L-shaped brace is used for reinforcing free-standing, light gauge, steel studs, gypsum board walls which are built up from a standard size, light-gauge track which is mounted to the floor. The brace has one leg which is fastened to the floor through the track, with the other leg extending vertically and being fastened either to one of a steel stud, or to the inside of a vertically extended length of track used to define the end of a free-standing wall.",
  "claims": [
    "1. A wall construction for producing a reinforced partial wall which terminates short of the ceiling and is of adequate strength despite the use of steel-stud construction, comprising: (a) a length of floor track mounted to an underlying surface; (b) a plurality of vertically extended, horizontally spaced steel-stud ribs defining a wall plane which extends up from the floor stopping short of the ceiling and has at least one unsupported end; (c) the lower ends of said ribs nesting in said track and being fastened thereto with at least one of said ribs being disposed near said unsupported end of said wall; (d) two gypsum sides sandwiching said ribs therebetween; and, (e) at least one L-shaped brace with legs of substantially greater thickness and strength than that of said ribs, and having one leg lying inside said track and being fastened directly and very securely to the underlying surface through said track with conventional fastener means designed to adequately withstand reasonable lateral forces expected from normal residential or commercial use, with the other leg extending upright and being fastened to said at least one of said ribs to reinforce same at the end of said wall, with said other leg extending up a substantial portion of the height of said wall to reinforce same well beyond the bottom region immediately adjacent said floor track.",
    "2. Structure according to claim 1 wherein said at least one of said vertical ribs disposed near one end of said wall terminates one end of said wall and is an inwardly concave track section, and said upright leg nests inside said track section.",
    "3. Structure according to claim 1 wherein said wall terminates at one end in an inwardly directed concave steel end stud, and including a special stud in said wall being concave towards said end stud, the upright leg of said L-shaped beam butting back-to-back against said special stud.",
    "4. Structure according to claim 1 wherein said legs comprise U-shaped channel members with the concave faces facing inwardly, and said one leg is fastened to the underlying surface by means of an apertured plate which fits inside said horizontal U-shaped leg and a heavy duty construction fastener which passes down through the aperture into the underlying surface.",
    "5. Structure according to claim 4 wherein said channel members are each made of 14 gauge steel, said upright legs is on the order of 24 inches tall and said horizontal leg is on the order of 6 inches tall such that a substantial portion of the height of said wall is directly reinforced by said brace."

  "description_excerpt": "A traditional wall for residential or light commercial/industrial buildings in the United States is made from soft wood 2\"×4\" studs which are vertically oriented and horizontally spaced on 16 inch centers, being capped at the top and the bottom with a 2\"×4\" header and footer, respectively. This frame is then sandwiched between gypsum board panels, sometimes referred to as \"drywall\".\n\nWalls made of wooden 2\"×4\" construction which do not go all the way to the ceiling, and define pony walls, stud walls or cubicle walls are naturally not as strong as the wall would be if it went all the way to the ceiling and was anchored to the ceiling joist structure. However, 2\"×4\" wooden stud construction is strong enough that free standing walls which don't reach the ceiling, or short walls terminating midway across a room, would nevertheless be strong enough with the drywall sheathing to stand up to normal use without additional support.\n\nRelatively recently a sheet metal channel stud has been introduced to the building industry as a replacement for the wooden 2×4 stud. Wall construction utilizing steel studs ordinarily incorporates steel tracks at the bottom and top of the wall. The steel tracks are similar in shape to the studs but are slightly wider to seat the stud top and bottom end within the tracks. The studs are fastened to the track with sheet metal screws, and drywall is subsequently applied in a manner similar to that in which it is applied to wooden stud walls when drywall screws are used instead of nails.",
