Abstract

A method of employing an adjustable apparatus for bracing one or both sides of a wall being fabricated from masonry blocks, with said wall having an opening near the base of the block wall. Bracing system includes strong rigid members assembled in the form of a right angle brace set having stiff vertical, horizontal and diagonal members, a connector having a length sufficient to extend through the opening affixed at a right angle location of one or both of the brace sets. A pair of such braces—back to back, and spaced on opposite sides of a wall—are interconnected together via this connector. Selected brace members telescope to accommodate increases in wall height and a manually adjustable outrigger screwjack at the remote end of the horizontal member eliminates reliance on prior art deadmen.

Claims9

Dependent claims

A method of bracing a wall fabricated from masonry blocks above a wall foundation by at least one first assembled right angle bracing set having rigidly connected vertical, horizontal and diagonal brace members assembled and connected together, with said vertical member being vertically plumb against said wall when said first right angle brace member is upright against said wall, said method comprising the steps of:

assuring that the block wall includes one only connector opening through the block wall being fabricated;
placing said one only connector opening near the base of the wall;
affixing, to the right angle portion of said first right angle bracing set, an adjustably tightenable connecting means which passes through said connector opening;
connecting the assembled right angle brace set to said wall at the lowest right angle connection location with freedom of movement by rotation and by tilting said assembled vertical, diagonal and horizontal members of said brace set;
initially letting said assembled first right angle brace set lie on the ground, but capable of manual rotation around said connecting means to a vertical position;
manually rotating said first right angle brace set into said upright position against said wall;
tilting the horizontal member at its end which is remote from the connector location, until the vertical member is flush against the wall;
and
tightening said connecting means in order to hold, free from further manual support, said first brace set in said upright position with said first set's vertical brace member held flush against the wall.

6 more elements

A method of using a pre-assembled rigid unitary right angle brace having interconnected horizontal, diagonal and vertical strength members rigidly connected together at a right angle for bracing a wall being fabricated from masonry blocks above a wall foundation, said method comprising:

locating a connector opening through the block wall being fabricated at about the first block course just above the foundation for the wall;
positioning an adjustable threaded connector bolt in said connector opening with an exposed portion thereof extending through the wall above said foundation;
selecting a tightening nut with mating threads for said connector;
loosely connecting said rigid unitary right angle brace to said connector bolt at the right angle portion thereof free from any buried in the ground anchor, in order to allow for manual rotation of said unitary right angle brace around said connector to a vertical position with said horizontal member of said rotated brace extending away from said wall and tilted roughly parallel to the ground;
adapting an adjustable jacking means sitting on the ground at the outermost end of said horizontal member of said unitary right angle brace for tilting the horizontal member as said jacking means is advanced or retarded;
manually operating said jacking means at the outermost end of said horizontal member of said unitary brace in order to tilt said unitary brace until said vertical brace member is flush against said wall surface and said horizontal member is essentially level with the ground;
tightening said connector nut sufficiently to bring the vertical member of said pre-assembled brace into non-wall-loading contact against said wall;
forming said right angle brace from tubular steel vertical, horizontal and diagonal support members;
a pair of spaced apart flanges which sandwich and rigidly affix said vertical and horizontal brace support members together into said unitary right angle brace with said connector bolt;
loosening and tightening nut located in an oversized opening in said vertical member and between said flange pair;
and
said vertical and said horizontal members each comprise inner and outer telescoping steel members for varying their length in order to accommodate increasing wall height.
