摘要： An adjustable brace for use by carpenters in the erection and plumbing of vertical walls during construction is disclosed. The brace comprises an elongated strut with a hinged wall anchor at one end and a hinged floor anchor at the other. This strut is suitably formed of two tube or pipe members of unequal length in end-to-end alignment and coupled together near the wall anchor end by a turnbuckle. When adjusted to its maximum length by manipulation of the turnbuckle, the strut is between 6 and 11 feet in length; and when adjusted to its minimum length, the strut is between 5 and 9 feet in length. Preferably it is about or approximately 8 feet in length, with its length adjustable over a span of at least 2 inches. At least one of the pivotally hinged anchors of the adjustable brace is characterized by having a lift-lip member under which the claw of a carpenter''s hammer is easily inserted to pry the anchor from a temporarily nailed position. In use, the wall anchor of one or more braces is temporarily nailed to a frame member of a preform structure designed for placement as a vertical wall in a building. Then the wall is placed in an estimated approximately plumb vertical orientation; and the floor anchors are temporarily nailed to the floor of the building. Turnbuckle adjustment is accomplished to place the wall in a true plumb vertical position, in which position the wall is held by the brace (or several braces) until sufficient structural elements have been added to the building to permanently hold the wall in position.
