A truss pitch break connector plate having a main body portion. A first stiffener flange projects generally perpendicular from one face of said main body portion along an arcuate first edge having an outer radius. A second stiffener flange projects generally perpendicular from the opposite face of the main body portion along a arcuate second edge having inner radius. The main body portion preferably is generally sector-shaped but alternatively it may be circular. The overall arrangement is such that the pitch break connector plate will accommodate top chords of different sizes; and is capable of maintaining the top chords at any one of a range of roof pitches.

DETAILED DESCRIPTION In its broadest aspects, the present invention provides a truss pitch break connector plate comprising main body portion having an arcuate first edge, an arcuate second edge, and opposite side edges.
A first stiffener flange extends along the arcuate first edge and a second stiffener flange extends along the arcuate second edge.
Further in accordance with the present invention, the truss pitch break connector plate comprises a generally sector-shaped main body portion presenting opposite faces, an arcuate first edge having an outer radius, and an arcuate second edge having inner radius.
A first stiffener flange projects from one of the opposite faces along the outer radius, and a second stiffener flange projects from one of the opposite faces along the inner radius.
The first and second stiffening flanges are generally perpendicular to the opposite faces of the main body portion, the first stiffening flange projecting from one face while the second stiffening flange projects from the other face in a direction opposite to that of the first stiffening flange.
Still further in accordance with the present invention, an apex joint between at least one top chord and one or more brace members of a roof truss is provided that incorporates connector means fixedly securing the top chord to the brace member to form the apex joint.
The present invention provides an improvement in the connector means comprising a plate having a sector-shaped main body portion overlying the top chord and underlying the brace member.
The main body portion includes an arcuate first edge having an outer radius, and a second arcuate edge having an inner radius.
A first stiffener flange is provided that extends along said outer radius and projects outwardly therefrom; a second stiffener flange is provided that extends along said inner radius and projects outwardly therefrom; and fastening means securing the main body portion to the adjacent upper ends.
Accordingly, it is the principal object of this invention to provide low cost, simple and useable connections for use in the apex joint or joints of a roof truss
