A rotation lever connected to the indoor and outdoor sides of the door body so as to be rotatably coupled through a medium, and a rotation support member of the rotation lever are respectively arranged vertically, and each end is rotatable through a rotation axis. A plurality of dogs that are coupled and lock while the other end is contacted and pressed with a stopper fixed to the door frame, or unlocked while being separated from the stopper, and a main one end is connected to the pivoting lever to rotate together according to the rotation of the pivoting lever. An elevating and descending link that integrally connects the other end of each of the plurality of driven pivoting links and the plurality of driven pivoting links up and down, and a plurality of driven pivoting links having one end connected to one end of each of the dogs and rotating together with each of the dogs. Including a link, the main rotational link is rotated according to the rotation of the pivoting lever, the lifting link is raised and lowered, and the plurality of driven pivoting links are rotated according to the lifting and lowering of the lifting link to collectively move the plurality of dogs. The door body is locked or unlocked with respect to the door frame by rotationally rotating, and the door body is an outer wall made of a glass fiber reinforced composite material that is cured by adhering multiple layers of fiber materials made of glass fibers with resin, and the Includes an inner member made by filling mineral wool, which is a mineral fiber, inside the outer wall, and the hinge is coupled to the door frame, and when the door body is closed to the door frame, the door body is locked on a surface facing the side of the door body. A door frame-side hinge bracket having a hole formed therethrough; a door-side hinge bracket inserted into the door frame-side hinge bracket so that the door frame-side hinge bracket and the hinge hole are connected to the door body, and the door frame-side A hinge pin having a fixing groove formed on the outer circumferential surface to be inserted into the hinge hole connected to the hinge bracket and the hinge bracket on the door side and connected to the locking hole formed through the hinge bracket on the door frame side, and a hinge screw coupled and fixed to the lower portion of the hinge pin. , A locking bolt penetrating through the locking hole of the hinge bracket on the door frame side and inserted and fixed into the fixing groove of the hinge pin, wherein the door body includes a rotation support member of the rotation lever, a rotation shaft of each of the dog and the hinge. It characterized in that it further comprises a fixing member made of a melamine fiber-reinforced composite material obtained by adhering multiple layers of a fiber material made of melamine fiber to the inside of the outer wall to fix and support each of the door hinge brackets by bolting. A weathertight fire door for a ship was disclosed.

However, in the prior art, since the outer wall is composed of glass fibers having relatively low durability and elasticity, there is a problem that the outer wall is easily damaged by surrounding foreigners (sea water, impact).
