A generator set housing has a skeletal frame with corners which conform to ISO standards. The frame members are welded together and are held in position during welding by tanging and wedging. This allows the frame to be self-squaring which eliminates the need for the use of jigs to hold the frame the together during welding. The skeletal frame is covered by panels which provide access to the generator set for service and repair. The panels are held in place by self drill and tap screws which are inserted from within the housing and would also be released from within the housing in order to enable removal of the panels. Folded sections are used throughout the housing. The dimensional accuracy is much greater due to the use of laser cutting to form the blanks from which the folded sections, including the tongues, which are integral, and the mating slots, were produced.
A fabricated structure comprising a skeletal framework of preformed elongate load bearing members joined one to another at certain joints so as to form openings therebetween, and non load bearing means for closing said openings, and a mechanical fixing arrangement for holding the pre-formed members in a precise relative location and orientation, one with respect to the other, and means for reinforcing each said certain joint by bonding to provide primary structural strength at each such certain joint, said mechanical fixing arrangement at each said certain joint of the framework comprising a tongue projecting from one end of a respective elongate load bearing member through a slot formed in the adjacent elongated member, said tongue having a slot, and a wedge received in the slot formed in said tongue, whereby the preformed elongated members are precisely located one relative to the other for said reinforcing means without the aid of an external jig.
A method of manufacturing a fabricated structure of a skeletal framework of elongate load bearing members when joined one to another so as to form openings therebetween and closure members to close said openings, said method comprising the steps of:
