PURLIN CONSTRUCTION FOR ROOF STRUCTURES

摘要

An elongated purlin for use in roof structures including an elongated solid continuous strip of metal, the strip of metal having multiple bends parallel with the longitudinal axis to form and define an elongated mounting wall, an elongated upright wall extending from the mounting wall, a first cross piece extending horizontally outwardly in opposite directions from the plane of the upright wall, a second cross piece integrally attached to the first cross piece and extending horizontally outwardly in opposite directions from the plane of the upright wall, and each of the first and second cross pieces having bent double layer construction. The first and second cross pieces are spaced apart to define channels designed to receive an edge of a solar panel or roof section engaged therein.

1. An elongated purlin for use in roof structures comprising:
an elongated solid continuous strip of metal with a longitudinal axis, the strip of metal having multiple bends parallel with the longitudinal axis to form and define: an elongated mounting wall designed to be mounted to and supported on roof beams; an elongated upright wall integrally affixed to and extending from the mounting wall and extending in a plane; a first cross piece integrally attached to the upright wall with a first portion and a second portion extending horizontally outwardly in opposite directions from the plane of the upright wall to form a T-shape with the upright wall, each of the first portion and the second portion of the first cross piece formed with bent double layer construction; a second cross piece integrally attached to the first cross piece with a first portion and a second portion extending horizontally outwardly in opposite directions from the plane of the upright wall to form a T-shape with the plane of the upright wall, each of the first portion and the second portion of the second cross piece formed with bent double layer construction; and the first cross piece and the second cross piece being spaced apart to define first and second horizontal channels opening outwardly in opposite directions from the plane of the upright wall, the first horizontal channel being defined between the first portion of the first cross piece and the first portion of the second cross piece and the second horizontal channel being defined between the second portion of the first cross piece and the second portion of the second cross piece, and each of the first and second channels being designed to receive an edge of a solar panel or roof section engaged therein.
