[0026] One end of the fireproof hinge 40 is provided on the door frame 10 , the door leaf 20 is provided on the other end of the fireproof hinge 40 , and the door leaf 20 is rotatably provided on the door frame 10 through the fireproof hinge 40 .
[0027] It should be noted that the fireproof hinge 40 described in this embodiment is a flag-type split hinge, which connects the door leaf 20 and the door frame 10 via the fireproof hinge 40 , thereby allowing the door leaf 20 to be rotated on the door frame 10 to open and close.
[0028] The door leaf 20 includes a door leaf panel 60 , rock wool 50 , a frame 70 and a fireproof expansion member 80 .
[0029] Among them, the door panel 60 is rotatably set on the door frame 10 through the fireproof hinge 40, the rock wool 50 is set in the door panel 60, the frame 70 is set in the door panel 60, and the fireproof expansion member 80 is set in the gap between the door panel 60 and the door frame 10.
[0030] It should be noted that the door panel 60 and the frame 70 are made of cold-rolled galvanized steel sheets, and the fireproof expansion member 80 is installed in the interlayer between the door panel 60 and the door frame 10 to ensure good sealing.
[0031] Specifically, the overall installation and use steps for a clean steel non-insulated fire door are as follows: First, the door leaf 20 is mounted on the door frame 10 using fire-resistant hinges 40. The interlayer between the two sets of door panels 60 on the door leaf 20 is filled with rock wool 50, and the rock wool 50 is also reinforced on the door frame 10 above the door panels 60. The door leaf 20 is opened and closed on the door frame 10 using a fire-resistant lock 30. Furthermore, the door leaf 20 maintains its sealing performance when opened and closed using a sweeping strip 10-3, effectively preventing pollutants such as outside air and dust from entering the clean area through the gap at the bottom of the door, thereby maintaining the cleanliness of the indoor environment.
[0032] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the door frame 10 includes a glass frame 10 - 1 , a temporary pull bar 10 - 2 , a sweeping bar 10 - 3 and a door frame frame 10 - 4 .
[0033] Among them, the glass frame 10-1 is set on the door panel 60, the temporary pull strip 10-2 is installed on the door panel 60, the sweeping strip 10-3 is set on the bottom wall of the door panel 60, and the door frame frame 10-4 is set on the door panel 60.
[0034] It should be noted that the glass frame 10-1 is installed on the door panel 60, and the thickness of the glass frame 10-1 is greater than the thickness of the door panel 60, and the surface of the glass frame 10-1 and the surface of the door panel 60 are located on the same horizontal plane, keeping the overall plane of the fire door neat and clean.
[0035] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, a protective glass 90 is provided on the inner wall of the glass frame 10 - 1 , a hollow cavity is provided between the two groups of glass frames 10 - 1 , and a fireproof expansion member 80 is provided between the glass frame 10 - 1 and the door panel 60 .
[0036] It should be noted that the inner wall of the glass frame 10-1 is provided with a protective glass 90, which is a tempered glass, and an air layer is provided in the hollow cavity provided inside the tempered glass. When the fire door is opened and closed, it is convenient to observe through the protective glass 90.
[0037] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the protective glass 90 is a single piece of non-insulating fireproof glass, and the two ends of the frame 70 respectively contact the surfaces of the two groups of protective glass 90.
[0038] It should be noted that the frame 70 described in this embodiment is made by processing cold-rolled galvanized steel plates. The frame 70 supports two sets of protective glasses 90, and the protective glasses 90 have good stability when installed on the door panel 60.

[0040] It should be noted that the rock wool 50 is filled in the interlayer of the door panel 60. As a high-efficiency, fire-proof and environmentally friendly inorganic thermal insulation material, the rock wool 50 is applied to the door panel 60. The door panel 60 has good fire-proof and environmentally friendly properties.
[0041] In one embodiment of the present invention, Figure 4 As shown, the door frame frame 10-4 is an L-shaped limiting frame, and the door panel 60 is abutted against the L-shaped limiting frame of the door frame frame 10-4.
[0042] It should be noted that the L-shaped limiting frame on the door frame frame 10-4 and the door panel 60 cooperate with each other, and the door panel 60 can only be opened and closed in one direction, thereby limiting the opening and closing of the door panel 60.
[0043] Specifically, the steps for installing and using the purified steel non-insulated fire door as a whole are as follows: first, the door leaf 20 is installed on the door frame 10 through the fireproof hinge 40. The two sets of door panels 60 on the door leaf 20 are filled with rock wool 50 in the interlayer, and the door frame 10 on the door panel 60 is also reinforced with the rock wool 50. The door leaf 20 is opened and closed on the door frame 10 through the fireproof lock 30. And the door leaf 20 maintains its sealing performance through the sweeping strip 10-3 when opening and closing. The glass frame 10-1 is embedded and installed on the door panel 60, and the protective glass 90 is installed on the glass frame 10-1. At the same time, the door frame frame 10-4 is installed on the door panel 60 and embedded in the rock wool 50 to enhance the overall stability. It can effectively prevent pollutants such as external air and dust from entering the clean area through the gap at the bottom of the door, thereby maintaining the cleanliness of the indoor environment.
[0044] In summary, a purification steel non-insulated fire door in an embodiment of the present invention adopts a door leaf panel to be rotated and adjusted on the door frame, and the door leaf panel is installed by limiting the fireproof expansion piece and the door frame frame to ensure that the fire door has good sealing performance. The design of sweeping strips and multiple frames enhances the overall strength of the fire door, avoids easy damage and reduces costs.
