[0026] like Figure 1-5 As shown, the embodiment of the utility model provides a radiation fire protection door, including a radiation protection door assembly 101, a door frame assembly 201, a threshold assembly 301 and a floor level 40;

[0027] The radiation protection door assembly 101 includes a radiation protection door body 10, a first barium sulfate fireproof composite plate 11, a first metal lead plate 12, a rectangular frame filled with fireproof rock wool 13, a second barium sulfate fireproof composite plate 14, a finished fireproof door 15, fixing bolts 16, a rotating bearing 17, a radiation-proof sealing strip 18, a fireproof sealing strip 19, a fireproof lock 110 and a galvanized sheet paint finish 111;

[0028] One side of the first barium sulfate fireproof composite panel 11 is fixedly connected to the inner wall of the radiation protection door body 10, one side of the first metal lead plate 12 is fixedly connected to one side of the first barium sulfate fireproof composite panel 11, and one side of the finished fireproof door 15 is installed on one side of the second barium sulfate fireproof composite panel 14.

[0029] In one embodiment, one end of the fixing bolt 16 passes through the interior of the radiation protection door body 10, and the outer side wall of the fixing bolt 16 is threadedly connected to the interior of the finished fire door 15. A rotating bearing 17 is installed on the outer side wall of the radiation protection door body 10. Through the setting of the fixing bolt 16, the finished fire door 15 can be installed in the interior of the radiation protection door body 10. Through the setting of the radiation protection door body 10, the rotating bearing 17 is fixed.

[0030] In one embodiment, a radiation-proof sealing strip 18 is installed on the outer wall of the radiation protection door body 10, and a fire-proof sealing strip 19 is installed on the outer wall of the radiation protection door body 10. Through the setting of the radiation protection door body 10, the radiation-proof sealing strip 18 and the fire-proof sealing strip 19 are fixed. The fire-proof sealing strip 19 is made of silicone rubber, has the characteristics of high temperature resistance, corrosion resistance, and oxidation resistance, and can withstand high temperature environment. Through the setting of the fire-proof sealing strip 19, when a fire occurs, the spread of fire can be prevented.

[0031] In one embodiment, a fireproof lock 110 is installed on one side of the radiation protection door body 10, and a galvanized sheet metal paint finish 111 is installed on the outer side wall of the radiation protection door body 10. Through the setting of the radiation protection door body 10, the fireproof lock 110 and the galvanized sheet metal paint finish 111 are fixed.

[0032] In one embodiment, the door frame assembly 201 includes a door frame body 20, a galvanized pipe 21, a third barium sulfate fireproof composite board 22 and a first barium sulfate cement mortar board 23; the outer wall of the galvanized pipe 21 is fixedly connected to the inner wall of the door frame body 20, one side of the third barium sulfate fireproof composite board 22 is fixedly connected to the outer wall of the galvanized pipe 21, one side of the first barium sulfate cement mortar board 23 is fixedly connected to one side of the third barium sulfate fireproof composite board 22, and one end of the rotating bearing 17 is rotatably connected to the bottom of the door frame body 20. Through the setting of the door frame body 20, the galvanized pipe 21, the third barium sulfate fireproof composite board 22 and the first barium sulfate cement mortar board 23 are fixed. The third barium sulfate fireproof composite board 22 is fixedly connected to the inner wall of the door frame body 20. It is made of barium sulfate powder and other additives. Barium sulfate is a common flame retardant with flame retardant effect. It can release a large amount of water vapor in a fire, thereby preventing the spread of fire and reducing the damage to the building caused by the fire. In a humid environment, the barium sulfate composite board can prevent it from entering the interior and keep the board dry, thereby reducing the chance of bacterial growth and maintaining the environmental hygiene of the building. The barium sulfate composite board has good radiation isolation performance and can block radiation from the external environment, thereby protecting the human body from radiation damage. In addition, the barium sulfate composite board has a long service life, is not easily affected by the external environment, has the characteristics of corrosion resistance and strong durability, and can be used for a long time in harsh external environments.

[0033] In one embodiment, the threshold assembly 301 includes a threshold body 30, a galvanized square tube 31, a second metal lead plate 32, and a second barium sulfate cement mortar board 33; the bottom of the threshold body 30 is installed on the top of the level 40, and one side of the threshold body 30 is fixedly connected to one side of the door frame body 20. The setting of the level 40 fixes the threshold body 30, and the setting of the door frame body 20 fixes the threshold body 30.

[0034] In one embodiment, one side of the galvanized square tube 31 is fixedly connected to the inner wall of the threshold body 30, one side of the second metal lead plate 32 is fixedly connected to one side of the galvanized square tube 31, and one side of the second barium sulfate cement mortar board 33 is fixedly connected to one side of the second metal lead plate 32. Through the setting of the threshold body 30, the galvanized square tube 31, the second metal lead plate 32 and the second barium sulfate cement mortar board 33 are fixed.

[0035] When the utility model is working: the utility model uses a composite structure of an independent finished fire door 15 and a radiation protection door body 10, so the radiation protection part has a higher radiation protection performance, and the finished fire door 15 has good fire resistance. When a fire occurs, by arranging a first barium sulfate fireproof composite board 11 and a second barium sulfate fireproof composite board 14 inside the radiation protection door body 10, barium sulfate can release a large amount of water vapor during a fire, thereby preventing the spread of fire and reducing the damage to the building by the fire. Barium sulfate also has good radiation isolation performance. Through the setting of the radiation protection sealing strip 18, the gap between the radiation protection door body 10 and the door frame body 20 can be protected to avoid radiation leakage and cause harm to the human body. Through the setting of the fireproof sealing strip 19, it can prevent flames from penetrating from the gap to avoid the spread of fire. The design of the utility model is reasonable, the structure is simple, and the work efficiency is improved.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
