LAMELLA FOR FIREPROOF GATES AND A FIREPROOF GATE COMPRISING THESE LAMELLAS
The invention relates to a lamella (1) for lamellar fireproof gates (9), in particular for high-speed lamellar fireproof gates (9), which contains a core (2) made of a thermal insulating material based on mineral and/or inorganic fibers, which is arranged between cover layers (3) of a foamed fire resistant geopolymer composite or of light-weight alkali-activated aluminosilicate, whereby the outer surface of the lamella (1) is overlaid with a steel sheet (6). A conical ridge (4) made of a non-combustible thermal insulating material is arranged on the longer side of the circumference of the core (2) of the lamella (1) along at least a part of the length of the core (2) of the lamella (1), whereas a conical groove (5) is arranged in the opposite longer side of the circumference of the core (2) of the lamella (1) along at least a part of the length of the core (2) of the lamella (1), whereby the conical groove (5) corresponds to the conical ridge (4) by its location, shape and size and is intended to receive the conical ridge (4) of the adjacent lamella (1), whereby the side walls and the top of the conical ridge (4), as well as the side walls and the bottom of the conical groove, (5) are overlaid with the steel sheet (6). Cooling holes (7) are formed in the steel sheet (6) which overlaps the sides and/or the top of the conical ridge (4) and in the steel sheet (6) which overlaps the sides and/or the bottom of the conical groove (5).In addition, the invention relates to a lamellar fireproof gate (9), particularly a high-speed lamellar fireproof gate, which contains these lamellas (1).
