Abstract

A metal roof truss assembly is provided comprising a plurality of elongated structural members, including a top chord, a bottom chord, and a web member. Each structural member comprises a planar base and planar legs extending from the longitudinal edges of the base. The base and the legs define an open longitudinal channel. A flange integral with the longitudinal edges of each leg has a planar first portion extending outwardly from the legs and a planar second portion extending from the longitudinal edges of the first portion of the flanges. The end of a first structural member is inserted into the channel defined by the legs and the base of a second structural member. The inserted end of the first structural member has no flanges for a length equal to at least the depth to which the first structural member is received in the channel of the second structural member so that the outer surface of the legs of the first structural member are adjacent the inner surface of the legs of the second structural member.

Dependent claims

A metal roof truss assembly, comprising:

a plurality of elongated structural members including a top chord, a bottom chord, and a web member, each structural member comprising
a planar base terminating in longitudinal edges;
planar legs extending from the longitudinal edges of the base and terminating in longitudinal edges, the legs extending the length of the base such that the base and the legs define an open longitudinal channel;
and
a flange integral with the longitudinal edges of each leg, each flange having a planar first portion extending outwardly from the legs and terminating in longitudinal edges, and a planar second portion extending from the longitudinal edges of the first portion of the flanges and terminating in longitudinal edges, the flanges selectively extending the length of the legs,
wherein the structural members are joined, the end of a first structural member at each junction being inserted into the channel defined by the legs and the base of a second structural member, the inserted end of the first structural member having no flanges for a length equal to at least the depth to which the first structural member is received in the channel of the second structural member so that the outer surface of the legs of the first structural member are adjacent the inner surface of the legs of the second structural member.

A method of forming a roof truss assembly, the method comprising the steps of:

providing a coil of substantially flat sheet metal;
cutting a plurality of lengths of the sheet metal;
forming structural members from each of the lengths of metal, wherein the structural members include a top chord, a bottom chord, and a web member, each structural member comprising a planar base terminating in longitudinal edges, planar legs extending from the longitudinal edges of the base and terminating in longitudinal edges, the legs extending the length of the base such that the base and the legs define an open longitudinal channel, and a flange integral with the longitudinal edges of each leg, each flange having a planar first portion extending outwardly from the legs and terminating in longitudinal edges, and a planar second portion extending from the longitudinal edges of the first portion of the flanges and terminating in longitudinal edges, the flanges selectively extending the length of the legs;
removing a portion of the flanges from an end of one of a first structural;
and
inserting the end of the first structural member into the channel defined by the legs and the base of a second structural member so that the outer surface of the legs of the first structural member are adjacent the inner surface of the legs of the second structural member.
