STRUCTURAL SYSTEM USING LIGHT WEIGHT METAL MEMBERS

摘要

Disclosed is a structural system comprising wall panels upon which floor and ceiling panels are supported. The various panels are composed of light-gauge metal structural studs and tracks. The studs and tracks are mechanically connected using a clinching machine for joining metal studs and tracks ranging in thickness from 16 to 20 gauge. The metal is preferably galvanized steel. The panels, as well as roof trusses, can be made in a plant where the panels can be surfaced or clad with insulation and specified finishes. The structural capacity of the panels is independent of any diaphram strength contributed by the cladding. Field erection of the panels to form a building may be carried out without resort to cranes due to the light weight nature of the panels and using unskilled labour. Field connections may be made using sheet metal screws or by clinching. The on-site joining of one panel to another uses a mating of stud to track in a parallel configuration in which the stud is nested in the track along the joint between panels. This provides a tight, structural continuity between panels. The use of a clinching machine in the manufacture of the panels to provide a mechanical joint equivalent in strength to a welded joint eliminates the need for worker protection from toxic fumes generated by welding galvanized metal, requires less extensive quality control and eliminates spot painting of welds for rust protection.
