Abstract

THE PRESENT INVENTION RELATES GENERALLY TO A METAL ROOF TRUSS (10) COMPRISING A LOWER CHORD MEMBER (12) AT OPPOSING ENDS BEING CONNECTED TO A RESPECTIVE OF A PAIR OF UPPER CHORD MEMBERS (14) AND (16). THE METAL ROFF TRUSS (10) ALSO COMPRISES A PLURALITY OF ELONGATE STIFFENING WEBS SUCH AS (18) AND (20) WHICH AT OPPOSING ENDS ARE CONNECTED TO THE LOWER CHORD MEMBER (12) AND ONE OF THE UPPER CHORD MEMBERS (14) RESPECTIVELY. THE STIFFENING WEBS SUCH AS (18) AND (20) ARE COLD ROLL FORMED FROM STRIP STEEL INTO A CHANNEL SECTION PROFILE INCLUDING A WEB (26) AND AN OPPOSING PAIR OF FILANGES SUDH AS (28) AND (30). ACCORDING TO ONE ASPECT OF THE INVENTION OPPOSING ENDS OF THE STIFFENING WEBS SUCH AS (18) AND (20) ARE CONFIGURED WHEREIN OPPOSING FLANGES SUCH AS (28) AND (30) OF THEIR RESPECTIVE STIFFENING WEB (18) OR (20) ENGAGE THE LOWER CHORD (12) AND ONE OF THE UPPER CHORDS SUCH AS (14). IN ANOTHER ASPECT THERE IS PROVIDED A METHOD OF FORMING ELONGATE STIFFENING WEBS SUCH AS (18) AND (20) AND/OR CHORD MEMBERS SUCH AS (12) TO (16). THIS INVOLVES PREFORMING ONE OR MORE PAIRS OF OPPOSING NOTCHES SUCH AS (36) AND (38) IN ELONGATE STRIP STEEL (40). THE PAIR OF OPPOSING NOTCHES (36) AND (38) PROVIDE A FRANGIBLE CONNECTION AT THE JUNCTURE OF ADJACENT STIFFENING WEBS SUCH AS (18) AND (20). THUS, THE VARIOUS COMPONENT OF THE METAL ROOF TRUSS CAN BE FABRICATED AS A "STRING" AND SEPARATED PRIOR TO ERECTION OF THE METAL ROFF TRUSS (10).(FIG 1)
