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.

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.
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.
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.
