Abstract
Abstract Bracing system for supporting masonry walls during construction utilizes metal braces arranged in opposed relation on opposite sides of the wall at spaced locations. Vertical support members are placed against each side of the wall and held tightly together by snap-tie members which are placed in the wall near its bottom during construction. Horizontal members extend outwardly from each vertical member and rest on the ground or on boards laid on the ground but are not anchored to the ground. Adjustable diagonal members connect the horizontal and vertical members to form a triangular brace on each side of the wall. The diagonal members are adjusted until the vertical members are pressed tightly against the wall adjacent their upper connections to the diagonal members. The weight of the braces are carried by the foundation, preferably by removable angle members laid over the edge of the foundation during construction. The angles include studs to which the horizontal members are attached. When building high walls, the wall is preferably supported as it reaches a height of about 10 or 12 feet. When the wall reaches a height of 20-24 feet, additional vertical members are linked to the previously positioned vertical members and pressed against the wall by additional diagonal members attached to the same horizontal members. The system permits the wall to resist moments as if it were supported as its top and bottom rather than as a cantilever and causes wind loads to be transferred through the masonry wall, into the brace, into the foundation wall and then into the ground. The system is quickly assembled and, except for the snap ties which are broken off inside the wall and covered over, reusable indefinitely.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
228 words
Apparatus for temporarily supporting a free-standing modular wall constructed on top of a foundation against wind damage during construction comprising: a first pair of rigid elongated members adapted to be placed vertically against opposing sides of the wall and in contact therewith throughout their lengths; means extending between said first pair of members intermediate the ends thereof adapted to be placed in said wall as it is being constructed for tying said first pair of elongated members to each other and to said wall and for transferring the stresses in said members produced by wind loading on the wall to the foundation of the wall; a second pair of rigid elongated members pivotally jointed at corresponding ends thereof to respective ends of said first pair of elongated members and projecting in opposite directions therefrom, said second pair of rigid elongated members being adapted to be supported against downward movement by the ground adjacent said foundation; a third pair of elongated compression members pivotally connected to each of said first and second pairs of elongated members so as to form a triangular brace on each side of said wall; one of said pairs of elongated members being adjustable to force said first pair of elongated members towards each other and the wall at the location where said first and third pairs of elongated members are connected to each other.
Claim 2
Dependent Claim

Apparatus for temporarily supporting a free-standing modular wall constructed on top of a foundation against wind damage during construction comprising: a first pair of rigid elongated members adapted to be placed vertically against opposing sides of the wall and in contact therewith throughout their lengths; means extending between said first pair of members intermediate the ends thereof adapted to be placed in said wall as it is being constructed for tying said first pair of elongated members to each other and to said wall and for transferring the stresses in said members produced by wind loading on the wall to the foundation of the wall; a second pair of rigid elongated members pivotally jointed at corresponding ends thereof to respective ends of said first pair of elongated members and projecting in opposite directions therefrom, said second pair of rigid elongated members being adapted to be supported against downward movement by the ground adjacent said foundation; a third pair of elongated compression members pivotally connected to each of said first and second pairs of elongated members so as to form a triangular brace on each side of said wall; one of said pairs of elongated members being adjustable to force said first pair of elongated members towards each other and the wall at the location where said first and third pairs of elongated members are connected to each other.
Claim 3
Dependent Claim
82 words
The apparatus of claim 1 wherein said means extending between said first pair of members comprises at least one tie rod member adapted to be placed in the wall at a distance above the foundation and a pair of support plates having portions adapted to lay on top of the foundation and portion extending ourwardly from the foundation, each of said pair of support plates being attached to one of said rigid elongated members for supporting the weight of said one member.
Claim 4
Dependent Claim
60 words
The apparatus of claim 2 wherein said at least one tie rod member is sufficiently long to extend through at least a portion of each of said first pair of elongated members and includes enlarged portions at its ends which are adapted to cooperate with wedge type fastening means to force said first pair of elongated members against said wall.
Claim 5
Dependent Claim
32 words
The apparatus of claim 2 wherein each of said first pair of rigid elongated members includes at least one elongated aperture therein adapted to receive said at least one tie rod member.
Claim 6
Dependent Claim
31 words
The apparatus of claim 1 wherein said means extending between said first pair of members comprises at least one tie rod member adapted to be placed on top of the foundation.
Claim 7
Dependent Claim
16 words
The apparatus of claim 1 wherein said third pair of elongated members are adjustable in length.
Claim 8
Dependent Claim
70 words
The apparatus of claim 6 wherein said third pair of elongated members comprise a pair of hollow end portions and a threaded center portion telescopically receivable inside said end portions, said threaded center portion engaging a threaded portion of one of said hollow end portions and being adjustably movable relative thereto, and means on said center portion for abuting the free end of the other of said hollow end portions.
Claim 9
Dependent Claim
62 words
The apparatus of claim 7 wherein said means for abuting comprises a rod, selectively transversely insertable in a plurality of apertures spaced along the length of said threaded center portion, said center portion being adapted to be rotated and thereby moved axially relative to said threaded hollow end portion by inserting an elongated handle in one of said plurality of spaced apertures.
Claim 10
Dependent Claim
145 words
The apparatuS of claim 1 wherein each of said first pair of elongated members comprises a first section adapted to be placed against said wall and pivotally connected to said second and third pairs of elongated members when the wall is at less than its final height and a second section adapted to be connected to said first section when said wall is at or at least close to its final height, said first and second sections including integral complementary end portions which interlock with each other to permit tension loading of said first pair of elongated members, and a fourth pair of elongated members pivotally connected to said second pair of elongated members at points remote from said third pair of elongated members and to said second section of said first pair of elongated members at a point spaced upwardly from said end portion.
Claim 11
Dependent Claim
82 words
The apparatus of claim 9 wherein said means extending between said first pair of members comprises at least one tie rod member adapted to be placed in the wall at a distance above the foundation and a pair of support plates having portions adapted to lay on top of the foundation and portions extending outwardly from the foundation, each of said pair of support plates being attached to one of said rigid elongated members for supporting the weight of said one member.
Claim 12
Dependent Claim

Claim 13
Dependent Claim
41 words
The apparatus of claim 1 wherein said means extending between said first pair of members ties said members to each other at locations which are spaced at least about 8 inches above the bottom of said pair of rigid horizontal members.
Claim 14
Dependent Claim
