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.

A wall brace system and/or a retainer member thereof that supports a structural member of the wall brace system, as well as a method of forming the retainer member. In particular, the retainer member includes tabs formed from the body of the retainer member. For example, the tabs may be formed from the edges of the retainer body or from within the edges of the retainer body. When installed, the wall brace system with the retainer member provides an apparatus for supporting a wall in a building structure, which has been moved inward by pressure from the earth outside in order to return the wall to a desired position. The wall brace system comprises a structural member, the retainer member, a mounting member, a load member, a jack, and/or a locking member.

A modular pipe brace assembly is provided for supporting a concrete wall panel, where the modular pipe brace assembly has a plurality of brace sections that each have a pipe with one of at least two standard lengths and a connection plate attached to each end of the pipe. At least two of the plurality of brace sections are attached together in longitudinal alignment by engaging the connection plates to define a pipe assembly with a desired length. An adjustable shoe assembly is attached to each end of the pipe assembly and is configured to engage a ground anchor or a concrete wall panel. The plurality of brace sections may, for example, include a low-load brace section that has a low-load capacity pipe and a high-load brace section that has a high-load capacity pipe.

Precast wall systems and methods for constructing a high-rise building using the precast wall system is disclosed. In one embodiment, the system includes a plurality of interconnected precast panels, each having a top end plate, a bottom end plate, a plurality of vertical bars disposed between the end plates and a cementitious material encasing the vertical bars and defining a plurality of sides of the respective panel. A first of the precast panels has a first column member half defining a right side of the first panel, a second of the precast panels has a second column member half defining a left side of the second panel such that, when the right side of the first precast panel and the left side of the second precast panel are disposed horizontally adjacent to each other, the first column member half and the second column member half collectively form a column member.

A plurality of panel subassemblies are used to erect a building on a footing or foundation. Each panel subassembly includes at least one column formed of a thermally-insulating material, and a concrete portion at least partially attached to the at least one column. The concrete portion may be formed as a single precast unit. The panel subassemblies are secured together and to the foundation, and may be secured to a floor element of the building to at least partially support the floor element.

A partition mount system includes an integrated plunger assembly. The integrated plunger assembly is constructed and arranged to be integrated into an interior of an end of an extension pole, for example a standard telescoping extension pole. Mounting of the plunger in an interior portion of the pole in this manner provides for a sleek design that is relatively lightweight. Assuming that the pole in which the anchor is mounted is part of a telescoping pole system, the anchor and plunger do not interfere with full travel of the interior pole with respect to other poles in the telescoping system. In this manner, operation of the telescoping pole system is not inhibited by the integrated plunger assembly.

The clip of the present invention comprises a main body having opposed front and rear faces, opposed first and second side ends and opposed top and bottom ends. The first side end has a first channel or groove formed therein and the second side end has a second channel formed therein. The length of the first channel is greater than the length of the second channel and the height of the second channel is greater than the height of the first channel. The top side of the main body has a first lip portion formed thereon and the bottom side has a second lip portion formed thereon. The first and second lips extend generally outwardly in the same direction relative to a face of the main body.
