ABSTRACT:
An improved design for square cornered ductwork (10) particularly suited for use in those applications requiring ductwork capable of resisting pressures of 40" to 50" water gauge or higher, and wherein such pressures in turn produce end reaction loads that exceed two kips in magnitude. The subject square corner ductwork (10) includes a first member (12), a second member (14) having a width substantially equal to that of the first member (12), a third member (16), and a fourth member (18) having a width greater than that of the third member (16). The first member (12) and the second member (14) each lie in a plane that extends parallel to that of the other. The third member (16) and the fourth member (18) each lie in a plane that extends parallel to the other, and perpendicular to the plane of each of that of the first member (12) and the second member (14). The first member (12) is secured to the third member (16) by means of a first weld (20) recognizable as a structural weld; and to the fourth member (18) by means of a second weld (22) recognizable as a structural weld. The second member (14) is secured to the third member (16) by means of a third weld (24) recognizable as a structural weld, and to the fourth member (18) by a fourth weld (26) recognizable as a structural weld.
