[0022] like Figure 1 The small ventilation box for a ribbed hollow floor slab shown includes a rectangular bottom plate 10, a rectangular top plate 11, a rectangular left side plate 12, and a rectangular right side plate 13.

[0023] The rectangular base plate 10, rectangular top plate 11, rectangular left side plate 12, and rectangular right side plate 13 are assembled to form a rectangular box structure with open end faces at both ends. The rectangular base plate 10 and rectangular top plate 11 have the same size, and the rectangular left side plate 12 and rectangular right side plate 13 have the same size.

[0024] The rectangular base plate 10 and the rectangular top plate 11 are the same size. The rectangular left side plate 12 and the rectangular right side plate 13 are made of fiber-reinforced calcium silicate board. The four parts are easy to process and have good fire resistance and pressure resistance.

[0025] The working principle is as follows: the open rectangular box body composed of rectangular base plate 10, rectangular top plate 11, rectangular left side plate 12, and rectangular right side plate 13 is connected at one end to the ventilation equipment and at the other end to the side plate of the ribbed hollow floor with ventilation openings, so that the air flow ventilation function can be realized when in use.

[0026] In addition, preferably as follows Figure 2 and Figure 3 As shown, the rectangular base plate 10 is provided with first fixed light steel angle keel 101 on both sides, the rectangular top plate 11 is provided with second fixed light steel angle keel 111 on both sides, and first self-tapping screws 102 are used to fix the rectangular base plate 10, the rectangular left side plate 12, and the rectangular right side plate 13 through the first fixed light steel angle keel 101, and second self-tapping screws 112 are used to fix the rectangular top plate 11, the rectangular left side plate 12, and the rectangular right side plate 13 through the second fixed light steel angle keel 111.

[0027] The above structural design allows for easy assembly. During assembly, the first self-tapping screw 102 is used to fix the connecting surfaces of the rectangular base plate 10, the rectangular left side plate 12, and the rectangular right side plate 13 using the first fixed light steel angle keel 101. Then, the second self-tapping screw 112 is used to fix the connecting surfaces of the rectangular top plate 11, the rectangular left side plate 12, and the rectangular right side plate 13 using the second fixed light steel angle keel 111. This design facilitates assembly and shortens construction time.

[0028] In addition, the preferred small ventilation box for the ribbed cavity floor slab further includes a first fireproof sealant layer 121 and a second fireproof sealant layer 131, which are respectively coated on both ends of the rectangular left side plate 12 and the rectangular right side plate 13, wherein the first fireproof sealant layer 121 and the second fireproof sealant layer 131 are fixedly connected to both ends of the rectangular left side plate 12 and the rectangular right side plate 13.

[0029] In the above structural design, during assembly, the first fireproof sealant layer 121 and the second fireproof sealant layer 131 are first applied to the end faces of the rectangular left side plate 12 and the rectangular right side plate 13 respectively, thus ensuring the overall ventilation box is airtight and free from smoke leakage.

[0030] In addition, the preferred small ventilation box for the ribbed cavity floor slab also includes a U-shaped reinforced light steel keel 14 that fixes the rectangular top plate 11, rectangular left side plate 12, and rectangular right side plate 13 through the second fixed light steel angle keel 111. After assembly, this improves the strength of the ventilation box and extends its service life.

[0031] In addition, the preferred small ventilation box for the ribbed cavity floor slab also includes a strip-shaped hoisting light steel keel 15 used in conjunction with the rectangular base plate 10 and the first fixed light steel angle keel 101, and perforated angle steel keels 16 set at both ends of the strip-shaped hoisting light steel keel 15, and a hoisting part 17 with one end fixed to the perforated angle steel keel 16 respectively; wherein, the hoisting part 17 is a steel wire rope or a screw with a nut. The above design structure can realize the hoisting and use of the ventilation box, improve its practicality, and the other end of the hoisting part 17 is connected to a fixed component (not shown in the figure, which does not affect the disclosure of the technical solution of this application).

[0032] In addition, the small ventilation box for the ribbed cavity floor slab preferably includes a set of fixed edge steel keel 18 and fixed middle steel keel 19 set on one end face of the rectangular base plate 10, wherein the fixed edge steel keel 18 is set in an L shape and the fixed middle steel keel 19 is set in an inverted U shape.

[0033] The above-mentioned design structure is used for horizontal auxiliary fixing during the construction or hoisting of the ventilation box. During horizontal auxiliary fixing, the fixed side steel keel 18 and the middle steel keel 19 are respectively fixed to the fixing components (not shown in the figure, which does not affect the disclosure of the technical solution of this application).
