[0039] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0040] This embodiment provides a ship, Figure 2-Figure 7 is a schematic diagram of this embodiment.

[0041] like Figure 2 The steel enclosure 200 of the ship is provided with a door opening 201 for installing the fire door 100. The overall structure of the fire door 100 is as follows: Figure 3-Figure 5 shown.

[0042] like Figure 3 The fireproof door 100 includes a door frame 1 and a door leaf 2. The thickness direction of the fireproof door 100 is the T direction, and the width direction is the W direction. The door leaf 2 is installed on the door frame 1. The door frame 1 has an opening groove 16 on one side of the T direction, so that the door frame 1 is concave. The opening groove 16 can be a buckle box for the door lock on the fireproof door 100 (see Figure 4) and the door sensor provide installation space, and at the same time can be used as a reserved deformation buffer space for the door frame 1. The door frame 1 is installed on the steel bulkhead 200, so that the door frame 1 and the steel bulkhead 200 of the hull are integrated into one structure, thereby improving the structural strength and anti-deformation ability of the steel bulkhead 200.

[0043] Such as Figure 3 , the door frame 1 has a first extension part 11, a second extension part 12, a third extension part 13, a fourth extension part 14, and a fifth extension part 15 connected in sequence. The first extension part 11, the third extension part 13, and the fifth extension part 15 extend along the T direction, and the second extension part 12 and the fourth extension part 14 are arranged in parallel, and the extension direction is perpendicular to the T direction.

[0044] Among them, the cross-sectional combination of the first extension part 11, the second extension part 12, and the third extension part 13 is in a [ shape to enclose an open slot 16. The first extension part 11 serves as the outer side wall of the door frame 1 and is parallel to the T direction, which is convenient for connecting the first extension part 11 and the steel bulkhead 200. Specifically, Figure 3 The approximate position of the steel bulkhead 200 is schematically shown by a dotted line in []. The steel bulkhead 200 extends perpendicular to the T direction and is fully welded to the first extension part 11, thereby improving the connection strength.

[0045] The extension length of the fifth extension part 15 is less than that of the third extension part 13. A seal 17 is installed in the L-shaped installation groove formed by the third extension part 13, the fourth extension part 14, and the fifth extension part 15. The seal is made of a fireproof material, for example, it can be made of fireproof rubber, to improve the sealing performance of the fire door 100 and meet the A-level fire protection requirements.

[0046] The door frame 1 provided by the present invention has a simple structure and is convenient to process. For example, it can be made by bending a steel plate. Specifically, in this embodiment, a steel plate with a thickness of 5 mm is bent to form the first extension part 11, the second extension part 12, the third extension part 13, the fourth extension part 14, and the fifth extension part 15 of the door frame 1, so that the structural strength of the door frame 1 is high enough. The door frame 1 with high structural strength is installed on the steel bulkhead 200 to strengthen the structure at the door opening 201, thereby improving the structural strength and anti-deformation ability of the steel bulkhead 200.

[0047] Such as Figure 4 , the door frame 1 is in a loop shape as a whole and completely surrounds the door leaf 2, so that the fire door 100 has a good fire protection effect while having a simple setting. In this embodiment, both the inner side and the outer side of the door frame 1 are rectangular.

[0048] Such as Figure 6 , the first extension part 11 is rectangular, and the four corners 111 of the first extension part 11 are all rounded to reduce stress concentration. Correspondingly, such as Figure 2The corners of the door opening 201 are also rounded to reduce the stress concentration of the steel surrounding wall 200 at this location, thereby improving the ability of the steel surrounding wall 200 to resist deformation.

[0049] like Figure 7 The thickness of the first extension portion 11 at the rounded corner is greater than the thickness of other parts of the first extension portion 11, so as to strengthen the structure at the rounded corner and improve the structural strength of the fire door 100. After the fire door 100 is installed on the steel enclosure 200, the structural strength and anti-deformation ability of the steel enclosure 200 can be further improved. Specifically, the first extension portion 11 includes a plurality of straight straight portions 112 and a plurality of arc portions 113. The arc portions 113 are welded to connect two adjacent straight portions 112. The thickness t2 of the arc portions 113 is greater than the thickness t1 of the straight portion 112. Further, as Figure 7 The arc portion 113 and the outer side of the straight portion 112 are arranged to be flush, so that the outer surface of the first extension portion 11 is continuous and smooth, so as to simplify the processing and manufacturing of the door opening 201 that cooperates with the first extension portion 11.

[0050] like Figure 6 The door frame 1 also includes a reinforcing plate 18, which is fixed in the opening groove 16 of the door frame 1 at intervals, and is specifically connected to the first extension portion 11, the second extension portion 12, and the third extension portion 13, so as to improve the structural strength of the fire door 100. Further, part of the reinforcing plate 18 is a first reinforcing plate 181, which is arranged at the arc portion 113 and connected to the arc portion 113, so as to strengthen the corner 111 of the door frame 1, and the strengthening effect is better. The other reinforcing plates 18 are second reinforcing plates 182, which are dispersedly arranged along the width direction W and the height direction H of the fire door 100, and the door frame 1 is structurally strengthened in the W direction and the H direction.

[0051] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
