Description

Technical Field

[0001] The utility model relates to the technical field of container production, and more specifically, to an A60 fireproof door for marine vessels. Background Art

[0002] For ship-type box power supplies that are maintained externally, it is generally necessary to use a side door opening method. This type of container, especially the side fire door, must meet the A60 fire rating requirements. The existing ship-type container fire doors can only meet the fire rating requirements on inland ships without taking up too much space, and the gap between this type of fire door and the box body is very small, which can easily cause the box door to be unable to open and close due to elastic deformation of the box body, affecting actual use. On river-sea direct or sea-going ships, A60-level fire doors that meet sea conditions are often large in size, occupy a lot of space, and are heavy in weight, which affects the internal battery capacity of the box-type power supply. They are also difficult to operate and are easily overweight. It is necessary to design a new type of A60 fire door for marine shipping that takes into account the fire rating requirements, is suitable for the marine environment, has little effect of elastic deformation on opening and closing the door, and has high structural strength.

DETAILED DESCRIPTION

[0038] Example:

[0039] The following is combined with Figure 1-5 The utility model is described in further detail.

[0040] A marine A60 fire door, such as Figure 1As shown, taking a double-door structure as an example, the fire door is installed on the container shell, and comprises a door frame 10, a left door leaf 20, a right door leaf 30, and a locking rod. The door frame 10 is additionally provided with an angle steel 18 to enhance the structural strength. A plurality of hinges are provided on the door frame 10, and the left door leaf 20 and the right door leaf 30 are installed on the left and right door frames 10 through the hinges. The door leaf can rotate relative to the door frame 10 through the hinge, and the door opening angle is close to 180°. The locking rod is correspondingly installed on the left door leaf 20, the right door leaf 30 and the container shell in a conventional manner.

[0041] like Figure 3 As shown, the door frame 10, the left door leaf 20, and the right door leaf 30 are all manufactured in the form of two steel plate parts spliced ​​together to form a frame. Specifically, an outer plate 40 is set on the opening side, and an inner plate 41 is set inside the box body. The outer plate 40 and the inner plate 41 are welded into a structure with a cavity in the middle. The gap between the door leaf and the door frame 10 is not more than 18mm, and the value is generally selected within ±2~3mm. Due to structural reasons, the structure of the outer plate 40 and the inner plate 41 of the door frame 10 is more tortuous, so the inner plate 41 and the outer plate 40 are collectively referred to, and the relevant structural shape is not restricted, nor is its use limited, but only its splicing function is referred to. The total thickness of the inner plate 41 and the outer plate 40 exceeds 3mm, and the optimal thickness is 4~6mm. This spliced ​​structure has guaranteed strength and is convenient for the subsequent installation of rubber strips. In addition, the left door leaf 20 and the right door leaf 30 are welded with a reinforcing plate 42 on the back side of the outer plate 40 to locally reinforce the connection area between the hinge and the lock rod to prevent the door leaf from being easily deformed due to mechanical stress or thermal stress.

[0042] The cavities of the door frame 10, the left door leaf 20 and the right door leaf 30 are filled with fireproof cotton 11. The fireproof cotton 11 at least meets the A60 fireproof grade, and generally uses A60 or A90 fireproof material.

[0043] like Figure 2 As shown, a crescent-shaped lock hook 17 is provided at the bottom of the lock rod, and a lock seat is provided in the area near the door frame 10. The lock is fixed by rotating the hook, and the lock rod drives the crescent-shaped lock hook 17 to rotate and hook or leave the lock seat. In the locked state, the container structure has a certain rigidity and can withstand harsh and changeable working conditions such as wave impact on the ocean. This design is conducive to the door leaf being able to open and close freely and maintain sealing and fireproof performance when the fire door is elastically deformed.

[0044] like Figure 4As shown, at the connection between the left door leaf 20 or the right door leaf 30 and the door frame 10, a side seam fireproof rubber strip 12 is provided on the back of the left door leaf 20 or the right door leaf 30, and a JC rubber strip 13 is provided on the front end, and a double rubber strip is provided between the door leaf and the door frame 10. The installation position of the side seam fireproof rubber strip 12 and the JC rubber strip 13 requires that the gap between the left door leaf 20 or the right door leaf 30 and the door frame 10 can be filled when the fire door is closed, and does not affect the normal opening of the fire door.

[0045] like Figure 5 As shown, at the overlap of the left door leaf 20 and the right door leaf 30, the non-hinged end of the left door leaf 20 is provided with an inner baffle 16 of a Z-shaped structure, and the non-hinged end of the right door leaf 30 is provided with a door baffle 15, the inner baffle 16 extends inward, and the door baffle 15 covers the outer side of the overlapping area. A middle seam fireproof rubber strip 14 is provided on the left door leaf 20, and its width is the same as the width of the gap between the left door leaf 20 and the right door leaf 30. A middle seam fireproof rubber strip 14 is also provided on the right door leaf 30, which fills the gap between the right door leaf 30 and the inner baffle 16 in the front-to-back direction. The two middle seam fireproof rubber strips 14 are attached to each other and arranged inward to fill the gap at the rear ends of the two door leaves. A JC rubber strip 13 is provided on the back of the door baffle 15, and the JC rubber strip 13 fills the back of the door baffle 15 and fills the front end gap between the two door leaves. The door stopper 15 is arranged so that the right door leaf 30 opens before the left door leaf 20, and the corresponding rubber strip realizes heat insulation and fire resistance of the center area.

[0046] The side seam fireproof rubber strip 12 and the middle seam fireproof rubber strip 14 initially have a compression amount, which is generally reasonable at 30% to 60%. All gaps are based on the closed state.

[0047] Compared with the 0.8-1mm thick thin iron sheet and latch-type locking rod used in conventional ships, the fire door of the present application has incomparable advantages in dealing with complex working conditions. The thickness of all door panels far exceeds the current fire door standards. The door hinges can effectively prevent the fire door from sagging and deforming. The crescent-shaped locking rod ensures that the fire door can still be opened and closed normally even when it is deformed. The total thickness of the door panel exceeds 3mm, and the optimal thickness is 4-6mm. The A60 fireproof cotton 11 is filled inside, which can meet the requirements of the overall structural integrity under the condition of burning for 60 minutes, and the temperature rise is within a reasonable range. The door leaf and the door frame 10 are set with a gap of about 18mm in the width and height directions, so that the fire door has more margin to tolerate the occurrence of elastic deformation compared with the traditional 3mm gap, and it is not easy for the door to be stuck and unable to open due to deformation of the door body. The external JC rubber strip 13 ensures the wind and rain sealing of the box body and meets the use requirements of the harsh and complex environment of shipping. The fire-resistant plug has a compression amount at the beginning, which not only ensures that the gap is filled in place during normal use, but also ensures that the gap or deformation area that may be generated after the fire is heated and expanded is blocked and supplemented, effectively preventing the spread of smoke and fire and hindering heat conduction. The structure of the double-opening door is slightly modified, and the middle seam area, door baffle 15, inner baffle 16 and other structures are deleted to apply to the single-opening situation. The inner door plate and the door baffle 15 are set on different door leaves, and the position can be swapped. The corresponding structure can be changed, and the principle remains the same.

[0048] The structure of the present application is applicable not only to side-opening containers, but also to rear-opening containers, and even to structures or ends that can be implemented on other containers. It can be applied to other products related to ships, not limited to ship containers.

[0049] The above-mentioned A60 fire doors for marine vessels are mainly used in marine energy storage containers, and it is not ruled out that they will be used in other marine-related scenarios in the future.

[0050] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
