Description
Technical Field
[0001] The invention relates to the technical field of nuclear power fire doors, in particular to a nuclear power fire door with a prefabricated door frame. Background Art
[0002] Nuclear power fire doors are fire doors specially used in high-security places such as nuclear power plants, designed to prevent the spread of fire or high-temperature smoke and ensure the safety of personnel and equipment. Existing nuclear power fire doors must have high fire resistance and are usually designed to maintain structural integrity for several hours in the event of a fire to ensure sufficient time for personnel evacuation and equipment protection; this type of door must not only block the fire, but also prevent the spread of harmful smoke, requiring good sealing performance; at the same time, nuclear power plants sometimes involve pressure changes, and fire doors must also withstand a certain amount of pressure; nuclear power fire doors are usually equipped with automatic closing systems that can automatically close in the event of a fire to prevent the spread of fire; and modern nuclear power fire doors often integrate intelligent monitoring systems that can detect the door's open state and whether there is an abnormality in real time, and will trigger an alarm system if there is a problem.
[0003] However, existing nuclear power fire doors generally transport the door frames to the installation site and install the door frames in the cast-in-place walls. This installation method not only requires on-site assembly and installation of the door frames, but also the connection strength between the door frames and the walls is insufficient, which can easily cause the door frames to detach from the cavity, posing a major safety hazard. Summary of the invention

[0027] See also Figures 1 to 4 The present invention discloses a nuclear power fire door with a prefabricated door frame, which includes a door frame assembly 100 and a door leaf assembly 200. After the door frame assembly 100 is prefabricated, it is connected to a wall 300 with a preset door opening by pouring. This installation method greatly enhances the connection strength between the door frame assembly 100 and the wall 300 without the need for secondary installation, thereby improving the installation convenience and stability of the nuclear power fire door; the door leaf assembly 200 corresponds to the door frame assembly 100 and is hingedly connected to the inside of the door frame assembly 100 to form a nuclear power fire door as a whole. Specifically, the door frame assembly 100 includes a door frame body 110 and a reinforcement member 120. The inner surface of the door frame body 110 corresponds to the door leaf assembly 200, and the outer surface of the door frame body 110 is embedded and installed on the surface of the wall 300 to ensure the close fit between the door frame body 110 and the wall 300. One end of the reinforcement member 120 is connected to the side surface of the door frame body 110 connected to the wall 300, and the other end of the reinforcement member 120 is embedded in the wall 300. Therefore, the reinforcement member 120 can further strengthen the connection strength between the door frame body 110 and the wall 300, thereby further improving the connection stability between the door frame assembly 100 and the wall 300, thereby effectively ensuring the sealing between the nuclear power fire door and the wall 300, and strengthening the fireproof and explosion-proof performance of the nuclear power fire door. In one embodiment, the door frame body 110 is made of profiles to strengthen the structural strength of the door frame body 110 to withstand the lateral pressure when the wall 300 is poured.
[0028] Furthermore, the door frame assembly 100 further includes a heat insulation unit 130, which is disposed on the inner wall surface of the door frame body 110 and connected to the wall 300, thereby ensuring the connection strength between the heat insulation unit 130 and the door frame body 110 and the wall 300. Specifically, when the door leaf assembly 200 is fitted into the door frame body 110, the edge of the door leaf assembly 200 is fitted and abutted against the heat insulation unit 130, thereby achieving a sealed connection between the door leaf assembly 200 and the door frame assembly 100, thereby improving the overall fire and explosion resistance of the nuclear power fire door.
[0029] Further, the door frame body 110 is set as a frame structure with an L-shaped cross section, and correspondingly, an installation groove with an L-shaped cross section is formed on the surface of the wall 300 during the pouring molding process, so that the door frame body 110 is closely attached to the inner corner of the surface of one side of the wall 300, thereby forming a tightly installed embedded door frame, so that the wall 300 can provide stable support to the door frame body 110, and the matching surface between the inner side of the door frame body 110 and the door leaf assembly 200 can be kept flat, thereby ensuring the matching degree between the door leaf assembly 200 and the door frame body 110. Specifically, one end of the reinforcement 120 is connected to the bend of the door frame body 110, and the other end of the reinforcement 120 extends toward the inside of the wall 300 and folds to form an L-shaped folded plate structure, thereby further improving the connection strength between the reinforcement 120 and the door frame body 110 and the wall 300, and preventing the door frame body 110 from falling off the surface of the wall 300.
[0030] Furthermore, the insulation unit 130 includes a carrier portion 131, an insulation portion 132 and a sealing portion 133. The carrier portion 131 forms a closed frame structure corresponding to the inner wall of the door frame body 110, and is connected to one side of the inner wall surface of the door frame body 110; when the door leaf assembly 200 is matched with the inside of the door frame body 110, the carrier portion 131 abuts against the edge of the corresponding side surface of the door leaf assembly 200; the insulation portion 132 is arranged on a side surface of the carrier portion 131 facing the door frame body 110, so that the insulation portion 132 can reduce the heat transfer between the inside and outside of the nuclear power fire door and reduce the risk of fire spread; the sealing portion 133 is arranged on a side surface of the carrier portion 131 facing the door leaf assembly 200, so that the sealing portion 133 can enhance the waterproof and smoke proof capabilities between the door leaf assembly 200 and the door frame body 110. In one embodiment, the carrier portion 131 is configured as a hollow tubular structure, and a side wall of the carrier portion 131 facing the door frame body 110 is connected to the inside of the wall 300 through a bolt structure 134 that sequentially penetrates the insulation portion 132 and the door frame body 110, thereby strengthening the connection strength between the carrier portion 131 and the door frame body 110 and the wall 300.
[0031] Furthermore, an abutment portion 310 is provided on the side of the wall 300 corresponding to the carrier portion 131 facing away from the door leaf assembly 200. When the carrier portion 131 is installed in place, the surface of the side of the carrier portion 131 facing away from the door leaf assembly 200 abuts against the surface of the abutment portion 310, thereby further improving the installation stability of the carrier portion 131 relative to the wall 300.
[0032] Furthermore, the door leaf assembly 200 includes a door leaf body 210, a hinge structure 220 and a fire lock 230. The door leaf body 210 is fitted inside the door frame body 110. At this time, the edge of the surface of the door leaf body 210 facing the insulation unit 130 is fitted and abutted against the sealing portion 133; one end of the hinge structure 220 is connected to the edge of the surface of the door leaf body 210 facing away from the insulation unit 130, and the other end of the hinge structure 220 is correspondingly connected to the door frame body 110, thereby realizing the hinged connection between the door leaf body 210 and the door frame body 110; the fire lock 230 is arranged at the other side edge of the door leaf body 210 relative to the hinge structure 220, and is fitted with the door frame body 110, thereby realizing the fitting locking between the door leaf body 210 and the door frame body 110. In one embodiment, the hinge structure 220 is configured as two heavy-duty door hinges, which are respectively arranged near the top and bottom ends of one side edge of the door leaf body 210 and are respectively connected to the door frame body 110, so as to enhance the hinge stability between the door leaf body 210 and the door leaf body 210.
[0033] Furthermore, the door leaf assembly 200 also includes a door closer 240, which is arranged at the top of the door leaf body 210 and is connected to the door frame body 110. The grounding terminal 241 of the door closer 240 is arranged on the door frame body 110 for a closed connection between the door leaf body 210 and the door frame body 110.
[0034] Furthermore, the door leaf body 210 includes two layers of galvanized steel plates 211, two layers of fireproof panels 212 and a fireproof door core panel 213. The two galvanized steel plates 211 are arranged on the two side surfaces of the door leaf body 210; the two fireproof panels 212 are respectively connected to the opposite side surfaces of the two galvanized steel plates 211; the fireproof door core panel 213 is arranged between the two fireproof panels 212, thereby forming the door leaf body 210 to ensure the fireproof and explosion-proof performance of the door leaf body 210.
[0035] To summarize, the nuclear power fire door with a prefabricated door frame disclosed in the present invention is prefabricated to obtain a door frame assembly, which is then connected to a wall with a preset door opening by pouring. This installation method greatly enhances the connection strength between the door frame assembly and the wall without the need for secondary installation, thereby improving the installation convenience and stability of the nuclear power fire door. The door leaf assembly corresponds to the door frame assembly and is hingedly connected to the inside of the door frame assembly to form a nuclear power fire door as a whole. Specifically, the door frame assembly includes a door frame body and a reinforcement. The inner surface of the door frame body corresponds to the door leaf assembly, and the outer surface of the door frame body is embedded and installed on the wall surface to ensure a close fit between the door frame body and the wall. One end of the reinforcement is connected to a side surface of the door frame body connected to the wall, and the other end of the reinforcement is embedded in the wall. Therefore, the reinforcement can further strengthen the connection strength between the door frame body and the wall, thereby further improving the connection stability between the door frame assembly and the wall, thereby effectively ensuring the sealing between the nuclear power fire door and the wall, and strengthening the fire and explosion-proof performance of the nuclear power fire door.
