Abstract
Abstract A reinforced truss includes a pre-existing top chord and a pre-existing bottom chord, a reinforcing top chord, first and second reinforcing chord heel plates, each of the reinforcing chord heel plates having a plate, a reinforcing truss bracket attached to a first end of the plate, at least one slotted aperture disposed on the plate and spaced to approximately match a pre-existing bolt pattern of the pre-existing truss, and a tie rod bracket. The ends of the reinforcing top chord are captured in the reinforcing truss brackets of the reinforcing chord heel plates. A tie rod is connected to the tie rod brackets of the first and second reinforcing chord heel plates. The slotted aperture allows for the tie rod to be adjusted, thereby adjusting the loading on the reinforcing top chord.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
145 words
A reinforced truss, including a pre-existing top chord and a pre-existing bottom chord, comprising: a first reinforcing top chord, having first and second ends; first and second reinforcing chord heel plates, each of the reinforcing chord heel plates having a plate, a reinforcing truss bracket attached to a first end of the plate, at least one slotted aperture disposed on the plate and spaced to approximately match a pre-existing bolt pattern of the pre-existing truss, and a tie rod bracket; the first end of the first reinforcing top chord captured in the reinforcing truss bracket of the first reinforcing chord heel plate and the second end of the first reinforcing top chord captured in the reinforcing truss bracket of the second reinforcing chord heel plate; and a first tie rod connected to the tie rod brackets of the first and second reinforcing chord heel plates.
Claim 2
Dependent Claim
145 words
A reinforced truss, including a pre-existing top chord and a pre-existing bottom chord, comprising: a first reinforcing top chord, having first and second ends; first and second reinforcing chord heel plates, each of the reinforcing chord heel plates having a plate, a reinforcing truss bracket attached to a first end of the plate, at least one slotted aperture disposed on the plate and spaced to approximately match a pre-existing bolt pattern of the pre-existing truss, and a tie rod bracket; the first end of the first reinforcing top chord captured in the reinforcing truss bracket of the first reinforcing chord heel plate and the second end of the first reinforcing top chord captured in the reinforcing truss bracket of the second reinforcing chord heel plate; and a first tie rod connected to the tie rod brackets of the first and second reinforcing chord heel plates.
Claim 3
Dependent Claim
89 words
The reinforced truss of claim 1 further comprising: second reinforcing top chord, having first and second ends; third and fourth reinforcing chord heel plates; the first end of the second reinforcing top chord captured in the reinforcing truss bracket of the third reinforcing chord heel plate and the second end of the second reinforcing top chord captured in the reinforcing truss bracket of the fourth reinforcing chord heel plate; and a second tie rod connected to the tie rod brackets of the third and fourth reinforcing chord heel plates.
Claim 4
Dependent Claim
22 words
The reinforced truss of claim 1, wherein the reinforcing truss bracket comprises a pair of planar bracket surfaces extending from the plate.
Claim 5
Dependent Claim
32 words
The reinforced truss of claim 3, where in the reinforcing truss bracket further comprises a third bracket surface parallel to the plate and attache d to the pair of planar bracket surfaces.
Claim 6
Dependent Claim
26 words
The reinforced truss of claim 1, wherein the slotted aperture comprises a plurality of slotted apertures, and wherein the slotted apertures are longer horizontally than vertically.
Claim 7
Dependent Claim
31 words
A reinforced truss, including a pre-existing top chord and a pre-existing bottom chord, comprising: a reinforcing top chord, having first and second ends; and means for compressing the reinforcing top chord.
Claim 8
Dependent Claim
31 words
A reinforced truss, including a pre-existing top chord and a pre-existing bottom chord, comprising: a reinforcing top chord, having first and second ends; and means for compressing the reinforcing top chord.
Claim 9
Dependent Claim
59 words
The reinforced truss of claim 6, wherein the means for compressing the reinforced top chord further comprises: first and second means for adjustably loading the reinforcing top chord connected to the first and second ends of the reinforcing top chord, respectively; and a tie rod connected to the first and second means for adjustably loading the reinforcing top chord.
Claim 10
Dependent Claim
62 words
The reinforced truss of claim 7, wherein each of the first and second means for adjustably loading the reinforcing top chord further comprises: a plate; means for capturing the reinforcing top chord; at least one slotted aperture disposed on the plate and spaced to approximately match a pre-existing bolt pattern of the pre-existing truss; and means for connecting to a tie rod.
Claim 11
Independent Claim
142 words
A method for reinforcing a truss, including a pre-existing top chord and a pre-existing bottom chord, comprising the steps of: loosely bolting a first reinforcing chord heel plate through at least one slotted aperture on the first reinforcing chord heel plate and through a first end of the pre-existing bottom chord; loosely bolting a second reinforcing chord heel plate through at least one slotted aperture on the second reinforcing chord heel plate and through a second end of the pre-existing bottom chord; installing a tie rod between the first reinforcing chord heel plate and the second reinforcing chord heel plate; installing a reinforcing top chord with first and second ends captured in brackets in the first and second reinforcing chord heel plates; tightening the tie rod; and tightening the bolts through the slotted apertures on first and second reinforcing chord heel plates.
Claim 12
Independent Claim
142 words
