Lamellas for lamellar fire gates, especially for high-speed lamellar fire gates, and lamellar fire gates, especially high-speed lamellar fire gates, containing these lamellas

摘要

Lamella (1) for lamellar fire gates (9), in particular for high-speed lamella fire gates (9), comprising a core (2) of a thermal insulation material based on mineral and / or inorganic fibers which is sandwiched between the covering layers (3) formed by a foamed refractory geopolymer composite or a lightweight alkali activated aluminosilicate, wherein the outer surface of the lamella (1) is covered with a steel sheet (6). On the longer side of the circumference of the core (2) of the lamella (1), a conical ridge (4) formed by a non-combustible heat insulating material is arranged at least over part of the length of the lamella core (1) and lamellas (1) in the opposite longer side of the core circumference (2). a conical groove (5) is formed over at least a portion of the length of the lamella core (1), which, by its position, shape and size, corresponds to a conical ridge (4) and which is intended for a conical ridge (4) of an adjacent lamella (1), wherein the side walls and the top of the conical ridge (4) and the side walls and bottom of the conical groove (5) are covered with a steel sheet (6) and in the steel sheet (6) overlapping the sides and / or the top of the conical ridge (4) and in the steel sheet ( 6) cooling openings (7) are formed over the sides and / or bottom of the conical groove (5). Another solution is lamellar fire doors (9), in particular high-speed lamellar fire doors containing these lamellas.
