Method for Production of a Wall of Gypsum Panels

Abstract

To produce the wall ( 1 ), gypsum panels ( 2 ) are mounted adjacent to each other on a frame ( 4 ). Instead of forming a strip made of flat gypsum panels against the frame on site, use is made of two-dimensionally shaped profile strips ( 3 ) which are made of plastic foam. In contrast to conventional finishing strips, these profile strips ( 3 ) are mounted not on the gypsum panels ( 2 ) but on the frame ( 4 ), in particular with one edge adjacent to one edge of the gypsum panels. A first part ( 9 ) of the visible side of the profile strip ( 3 ) here lies in the extension of the surface formed by the gypsum panel ( 2 ) while a second part ( 10 ) of the visible side of the profile strip ( 3 ) protrudes from this surface. The profile strip ( 3 ) is chamfered at the edge adjacent to the gypsum panel ( 2 ) to form a chamfered edge zone ( 8 ). With the profile strip in mounted state, this chamfered edge zone forms a groove ( 11 ) that is filled with caulking agent ( 12 ). The new method allows, on production of a wall with gypsum panels, the integration of a strip in the gypsum panels in a simpler and less time-consuming manner.
