Abstract: Disclosed is a fire protection dividing wall for installation between construction parts of a building. The wall is assembled of a supporting frame carrying fire protection glass panes. The frame is assembled of a steel core which includes upright struts and horizontal tie bars which carry the glass panes. The frame core is preferably made of steel tubes of rectangular cross section. The struts are provided with opposite projections which are inserted into the ends of the tie bar sections. The opposite outer sides of the frame cores are covered with covering rails of hard wood, which has approximately the same fire-resistant time factor as the glass panes. The gaps between the covering rails and the glass panes are sealed by a fire-resistant sealing mass.
