The intermediary wall comrpises a number of sections (1-4) and a door aperture (10). Floor bases (5,6) extend from the outer walls (14,15) to the door aperture and have the same thickness as the wall sections. They also have a groove or a lip in their top edges. - The wall sections rest on the floor bases, with which they are ned by tongues working in conjunction with the grooves of lips. They are fixed to the ceiling by a pair of fillets forming a longitudinal track for their upper edge parts. The width of the wall sections is less than that of the door aperture. A wall piece (11) with the same thickness as the wall sections is fitted above the door above the door aperture after the main wall sections have been pushed into position. |
