METHOD AND APPARATUS FOR PRODUCING LEAF MOBILE fire barriers for building structures, as well as making this way VENT MOBILE FIRE BARRIERS FOR CONSTRUCTION

摘要

The invention relates to a method for producing a fire prevention closing wing (33, 16), especially a fire door panel (16), comprising an outer housing (7, 19), especially made of sheet metal and enclosing a filling material (13) made of mineral substances (2, 25) and binding agents (6). The aim of the invention is to produce a fire prevention closing wing in a cost-effective manner. In order to achieve this, the outer housing (7, 19) comprises a cavity which can be accessed from outside by means of at least one housing opening (11, 22), said housing opening being preferably smaller than the cavity in terms of length and/or width. A mineral-based loading agent (2, 25), either in bulk or in liquid form, and an inorganic binding agent (6) are introduced via the at least one housing opening (11, 22) to form the filling material (13). The invention also relates to a device for carrying out said method and a fire prevention closing wing produced (13) therewith.
