Abstract: The reinforcing brace frame is utilized in building walls as a complete system of protection against both the severe shear stress and uplifting encountered during tornadoes, hurricanes and earthquakes. The reinforcing brace frame includes two vertically-spaced horizontally extending frame members joined at their opposite ends to two horizontally-spaced vertically extending frame members, and a diagonal member rigidly connected to opposite ends of the horizontally extending frame members. The reinforcing brace frame can also include spaced vertical support members between the vertical frame members. The reinforcing brace frame is directly attached to a concrete foundation by shear bolts and hold down bolts. Consequently, the reinforcing brace frame provides increased resistance against simultaneous shear stress and uplifting, eliminating the need for plywood shear panels.

Abstract: A brace structure includes a top plate of a wood-frame structure with a first plate vertically oriented on one side of the top plate and a second plate vertically oriented on the other side of the top plate. Two strips extend between the first edge and the second edge across the top plate. The strips include a space therebetween for passage of utility conduits. The plates have flanges for strength along the edges connecting the two strips. The plates also have fasteners therethrough and into the top plate.

Abstract: An apparatus for providing a self-adjusting tie down includes a bolt extending into a foundation and a nut on that bolt which is supported by two shims, one of which can move relative to the other. A spring exerts substantially constant force on the movable shim, preventing gaps from forming between the nut and the shims underneath.

Abstract: The improved reinforcing brace frame is utilized in building walls and the like to increase their resistance to severe stress such as it encountered during earthquakes, tornados, hurricanes, cyclones and other high wind situations. The frame is all metal, preferably steel and includes a vertically spaced pair of horizontally extending frame members joined at their opposite ends to a spaced pair of vertically extending frame members. The frame also includes a diagonal member rigidly connected to opposite ends of the horizontally extending frame members. Preferably, each of the horizontal frame members and the diagonal member include a pair of telescoping members so that the brace frame can be expanded and contracted in width to fit into a desired wall space. In one embodiment, the vertically extending frame members also each include a pair of telescoping members to control the heighth of the brace frame.
