<p>A profile tube (7) which is used for the location of vertical wall panels (1) has a cross sectional profile in the form of a cross. Each member of the cross consists of two parallel strips, between which the wall panels are located. On the inside of each strip, a longitudinal ridge (5) is provided. The ribs engage into matching grooves (81) in the wall panels when the two are assembled. Thus the panels (1) are secured in their installation position. Cover channels (24) are inserted into panel locations which are not required.</p> |
