Technical Field

[0001] The utility model relates to the field of containers, in particular to an A60 fireproof floor structure of a container. Background Art

[0002] As the development trend of electric ship shipping in inland rivers becomes more and more favorable, the demand for replacing traditional fuel power with new energy pure electric drive is gradually increasing, which puts higher requirements on the capacity of box-type power supply. In order to meet the fire protection requirements of marine A60, the floor needs to avoid thermal bridges between the battery rack and the back of the floor within a certain distance; at the same time, more space needs to be left for the battery, the thickness of the floor needs to be further compressed, and a certain floor structure strength needs to be met.

[0003] In the prior art, the floor is mostly made of C-shaped angle steels arranged closely to ensure the rigidity of the structural floor. At the same time, in order to meet the A60 fire protection requirements, the floor is fully covered with insulation cotton. This solution can meet the fire protection and structural strength requirements, but the required material cost is high and a large amount of insulation cotton and insulation cotton sealing board are required. Utility Model Content

[0004] The utility model aims to provide an A60 fireproof floor structure for a container, which can meet the A60 fireproof requirements and at the same time meet the structural strength requirements of the floor with a thinner floor.

[0006] Therefore, the utility model improves the rigidity of the entire floor by bending the steel floor by setting grooves, and the supporting square tubes of the battery rack can also utilize the grooves to achieve vertical installation of the long sides, and have better rigidity in the longitudinal direction. After the two are combined, the rigidity of the entire battery box floor can be improved without increasing the thickness of the floor, and the probability of floor deformation can be reduced; at the same time, only a corresponding fireproof cotton structure is added to each supporting square tube, which can meet the A60 fire protection grade requirement of the floor while greatly saving the cost of fireproof cotton materials.

[0007] Preferably, the fireproof cotton structure includes an A60 fireproof cotton sealing plate and two symmetrically arranged side structures, the upper sides of the side structures are connected to the steel floor, the lower sides of the side structures are connected to the A60 fireproof cotton sealing plate, and A60 fireproof cotton is arranged between the two side structures, the steel floor and the A60 fireproof cotton sealing plate. Thus, a specific fireproof cotton structure matching groove and vertical supporting square tube is provided.

[0008] Preferably, the side structure is a C-shaped angle steel, and the opening directions of the two side structures are opposite. Therefore, the utility model can utilize the existing C-shaped angle steel used to enhance the rigidity of the floor in the prior art, and arrange the two C-shaped angle steel openings opposite to each other to realize the fireproof cotton structure.

[0009] Preferably, the two side structures are symmetrical about the supporting square tube, and the distance between the opposite sides of the two side structures is at least 450 mm, so that the distance between the side structures of the fireproof cotton meets the fire protection requirements required for the thermal bridge position, i.e., the contact point between the lower side of the supporting square tube and the steel floor.

[0010] Preferably, the groove is in an inverted trapezoidal shape, the lower side of the supporting square tube is connected to the middle of the upper bottom of the groove, and the upper side of the supporting square tube is used to support the battery rack. Therefore, the groove structure can facilitate the A60 fireproof material to be better filled into the groove on the one hand, and also provide sufficient operating space to facilitate the vertical installation of the supporting square tube on the other hand.

[0011] Preferably, the lower side of the steel floor is also closely arranged with C-shaped angle steels. Thus, the C-shaped angle steels in the prior art are used on the lower side of the steel floor to enhance the rigidity of the entire floor. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] See also Figure 2 and Figure 3 The utility model discloses a container A60 fireproof floor structure, including a supporting square tube 1 and a steel floor 2. The steel floor 2 is provided with a groove downward, and the groove is in an inverted trapezoidal shape. The upper bottom and both side edges of the groove are the upper side surfaces of the steel floor 2, so that the steel floor 2 forms a bending structure, thereby improving the rigidity of the overall floor.

[0016] Reference Figure 1 In the prior art, the supporting square tube 1 is installed on the surface of the steel floor 2 with its short side erected. Figure 1 The installation position of the middle supporting square tube is to install the supporting square tube 1 with the long side vertically inside the groove, and the lower side of the supporting square tube 1 is welded to the middle part of the upper bottom of the groove; the vertical supporting square tube 1 protrudes from the groove, and the height is higher than the upper surface of the steel floor 2, and the upper side of the supporting square tube 1 is used to support the battery rack. The vertical installation of the supporting square tube 1 fully utilizes the space of the bending structure of the steel floor 2, so that the overall floor has better rigidity in the longitudinal direction.

[0017] The upper surface of the steel floor 2 and the outer side of the supporting square tube 1 are paved with A60 fireproof material 3. In this embodiment, the A60 fireproof material 3 is anticorrosive cement, and the thickness of the anticorrosive cement must at least reach the upper side of the supporting square tube 1. The bending structure can facilitate the A60 fireproof material 3 to be better filled into the groove, and on the other hand, it also provides sufficient operating space to facilitate the vertical installation of the supporting square tube 1.

[0018] A group of fireproof cotton structures 4 is correspondingly arranged under each supporting square tube 1. The fireproof cotton structure 4 is arranged on the lower side of the steel floor 2, and includes an A60 fireproof cotton sealing plate 42 and two symmetrically arranged side structures 43. The two side structures 43 are symmetrical about the supporting square tube 1, and the distance between the opposite sides of the two side structures 43 is at least 450 mm, so as to meet the fire protection requirements of the thermal bridge position, i.e., the contact point between the lower side of the supporting square tube 1 and the steel floor 2. The upper side of the side structure 43 is welded to the steel floor 2, and the A60 fireproof cotton sealing plate 42 is welded to the lower side, so that a closed space is formed between the side structure 43, the steel floor 2 and the A60 fireproof cotton sealing plate 42, and the closed space is filled with A60 fireproof cotton 41. In this embodiment, the A60 fireproof cotton 41 is rock wool. In this way, not only can the requirements of the A60 fire protection grade be met, but also a large amount of fireproof cotton material costs can be saved. Figure 1 The existing technology in the invention also reduces the thickness of some fireproof cotton.

[0019] In addition to the fireproof cotton structure 4, the lower side of the steel floor 2 also needs to be closely welded with C-shaped angle steels 5. In this embodiment, the side structure 43 can also use C-shaped angle steels 5, and the opening directions of the two C-shaped angle steels 5 of the side structure 43 are opposite. Therefore, the utility model not only utilizes the existing C-shaped angle steels 5 used to enhance the rigidity of the floor in the prior art, but also can realize the fireproof cotton structure 4 by arranging the openings of the two C-shaped angle steels 5 closest to the supporting square tube 1 opposite to each other.

[0020] In summary, the utility model improves the rigidity of the entire floor by setting a groove to bend the steel floor 2, and at the same time uses the long side of the bent space to vertically install the supporting square tube 1, thereby improving the rigidity of the entire floor without increasing the thickness of the floor and reducing the probability of floor deformation; at the same time, only a corresponding fireproof cotton structure 4 is added to each supporting square tube 1 to meet the A60 fireproof grade requirements of the floor. Based on the above embodiment, the structure of the utility model can not only meet the rigidity of the floor and the A60 fireproof grade requirements, but also save a lot of fireproof cotton material costs compared to the prior art, and reduce the overall floor thickness. The overall floor thickness of the prior art is about 30% thicker than that of the present embodiment.

[0021] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
