Description
Title of the invention: Renovated fire-resistant armored door technical field
[0001] The present invention relates to a fire-resistant armored door. The invention will find particular application in integrating fire-resistant and armored functions into an existing door. The invention is particularly applicable to the renovation market. STATE OF THE ART
[0002] The principle of a fire door is to limit the risk of fire spreading from one apartment to other apartments, particularly to the corridors of common areas. Therefore, it is necessary to limit the diffusion of heat towards the core of the door. However, armored doors have a metallic coating that conducts heat particularly well towards the core of the door.
[0003] Furthermore, a solution applicable to existing doors, generally made of wood, is sought for the purpose of saving money, but also as part of an ecological and aesthetic approach whose objective is to use existing materials as much as possible.
[0004] There is therefore a need to offer an armored fire door which resolves all or part of these drawbacks. SUMMARY
[0005] To achieve this objective, according to one embodiment, an armored fire door is provided comprising a frame and at least one leaf, the leaf comprising a base panel, for example made of wood, comprising an external face intended to form an exterior face of the fire door and an internal face opposite the external face, the internal face and the external face being connected to each other by an edge, at least part of the internal face and at least part of the edge being covered, preferably entirely, by a metallic armoring cladding having a first face disposed with regard to the base panel and a second face opposite the first face,characterized in that the opening comprises a fire-resistant magnesium silicate panel bonded with non-combustible adhesive between the inner face of the base panel and the first face of the metal armor cladding, and in that at least a portion of the edge of the opening comprises a non-combustible wool seal arranged between the base panel and the first face of the metal armor cladding.
[0006] This configuration ensures that the wooden base panel is protected to delay the temperature rise and its combustion despite the presence of the metallic shielding cladding. Indeed, the synergy between the fire-resistant panel bonded with non-combustible adhesive, which both reduces the temperature and Preventing combustion, the non-combustible wool seal, which provides a thermal barrier in sensitive and less accessible areas such as the edges of the openings, allows for a renovated, easily installed, and highly effective fire-resistant door. The door according to the invention is at least a fire-resistant door, fire-rated E1, and advantageously offers 30 minutes of flame resistance, corresponding to an E30 classification.
[0007] Advantageously, the synergy of the wool and the insulating panel makes it possible to ensure optimal protection of at least three sides of the door.
[0008] According to one possibility, the fire door comprises two openings.
[0009] According to another aspect, the invention relates to a method for renovating a door, preferably an existing one, to close off an area in order to form a fire-resistant armored door as described above: (the area being, for example, an apartment, a house) - Supply of an existing door with a base panel, for example made of wood, comprising an external face intended to form an outer face of the armored fire door and an internal face opposite the external face, - Application of a magnesium silicate fire-resistant panel to the inner face of the base panel using a non-combustible adhesive, - Positioning of a non-combustible wool seal on at least part of the edge of the base panel, - Positioning of a metallic shielding coating (500) on at least part of the inner face (303,403) of the base panel and on at least part of the edge.
[0010] This process makes it possible to improve the existing door by adding armoring and fire-resistant functions while keeping the external face in contact with the outside of the area, therefore visible from the outside with the original aesthetic. BRIEF DESCRIPTION OF THE FIGURES
