<p>Wall panels having thermal insulation sandwiched between opposed metal skins, are joined together to provide a rigid joint which is flush and vacuum tight. Narrow heavy gauge elongated strip plates fit precisely within offsets in both skins adjacent to the joining surfaces, and are bolted to the skins. One strip plate includes internally threaded holes in which the fastening bolts are inserted and engaged from within the panel using a screwdriver or a wrench which passes from the opposite side through a clearance channel in the panel. The other plate is held on the opposite panel side by bolts which engage threaded nuts attached to the adjacent offset skin portions. All bolt fasteners are accessible and attached from the same wall surface, with the bolts within the panels passing freely through the threaded nuts on the opposite skin. Accurate spacing of the holes in the strip plates and skin offsets assures a compressed butt joint between the insulation of the clamped panels. In an alternative embodiment of this invention, the ends of the panels to-be-joined are provided with offsets which interlock and provide alignment of the adjacent panels before and after they are clamped together with bolts.</p> |
