Abstract
The subject of the present invention is a watertight fire door for closing an opening in a building or edifice comprising, on the one hand, a fixed frame and at least one opening leaf and, on the other hand, sealing means that provide sealing between the fixed frame and the opening leaf when the door is closed. The or each opening leaf comprises, on the one hand, a framework surrounding an empty space capable of accepting or forming a thermal insulator and being sandwiched between two layers and of thermal insulation each essentially produced from a material having low thermal conductivity or diffusivity and, on the other hand, if appropriate, at least one thermal break.
Claims20
A fluidtight fire door for closing an opening in a building or edifice, comprising:
- a frame;
- at least one opening leaf including two broad faces and, opposite and parallel to one another, such that a first broad face and a second broad face are bounded laterally by narrow faces, forming an edge of the at least one opening leaf, which are perpendicular to the broad faces;
- and,
- a joint, ensuring tightness between the frame and the at least one opening leaf in a closed state of the door,
- wherein the at least one opening leaf includes a metal framework surrounding an empty space capable of receiving or forming a thermal insulator and held between two layers of thermal insulation, extending parallel to the broad faces of the at least one opening leaf, such that a first layer is located beside the first broad face and a second layer is located beside the second broad face, the first and second layers being capable of preventing, in an event of one of the broad faces or being exposed to fire, propagation of heat radiation from the latter to the other one of the broad faces.
