Description

Technical Field

[0001] The utility model relates to the technical field of fireproof doors, and more specifically to an internal strengthening connection structure of a fireproof door. Background Art

[0002] In addition to the functions of ordinary doors, fire doors can also prevent the spread of fire and smoke. They can prevent the spread of fire for a certain period of time and ensure the evacuation of personnel. With the progress of society, the frequency of use of fire doors is increasing. Fire doors must have high strength and other properties while having fire-proof properties.

[0003] After searching, the utility model patent with announcement number CN211776921U discloses an internal reinforced connection structure of a fire door, including a titanium-zinc composite plate, and a reinforced connection fire protection mechanism is arranged on both sides of the titanium-zinc composite plate; the reinforced connection fire protection mechanism includes a fixed shell, cooling water, a fiber cement board and a first slot; a plurality of fixed shells are fixedly connected at equal distances on the left and right sides of the titanium-zinc composite plate, and a damping block is fixedly connected between the plurality of fixed shells, the interior of the fixed shell is filled with cooling water, and the left and right sides of the titanium-zinc composite plate are bonded with fiber cement boards; this patent can not only increase the fireproof ability of the fire door by using the fixed shell on the titanium-zinc composite plate and the cooling water in the fixed shell, but also increase the connection strength inside the fire door by plugging the fixed shell and the fiber cement board, and not only that, the cooling water is filled inside the fixed shell to prevent the door body from overheating during fire prevention.

[0004] However, the above patents still have the following shortcomings: the plug-in structure of the fixed shell and the fiber cement board is not convenient for ensuring the uniformity of the door body strength, the gaps between the fiber cement boards cannot be well supported and reinforced, and the effect of relying on the water inside the fixed shell to dissipate heat from the door body is poor. At the same time, water will expand when heated, and the expanded water vapor will squeeze the fixed shell from the inside, affecting the stability of the door body. For this reason, we propose an internal reinforcement connection structure for fire doors. Utility Model Content

[0031] In this embodiment, the inner cavity of the water storage tank 14 is provided with water, and the push box 12 is thermally conductive.

[0032] For details, please refer to Figure 2 , Figure 3 and Figure 5 The end surface of the serpentine reinforcement plate 7 is connected to the side surface, top surface and bottom surface of the inner cavity of the reinforcement groove 2.

[0033] In this embodiment, the stability of the serpentine reinforcement plate 7 in the reinforcement groove 2 is ensured, thereby ensuring that the fire door body 1 is reinforced.

[0034] For details, please refer to Figure 6 Two support blocks 15 are fixedly connected to the ends of the push box 12 , and a spring 16 is fixedly connected between the support block 15 and the piston plate 13 .

[0035] In this embodiment, when the piston plate 13 moves outward, the spring 16 is moved, and after the water in the water tank 14 cools down, the elastic force of the spring 16 drives the piston plate 13 to return to its original position.

[0040] Working principle: When in use, the serpentine reinforcement plate 7 and the support plate 8 are used to support the reinforcement groove 2 in the fire door body 1. At the same time, the serpentine reinforcement plate 7 and the support plate 8 are used to strengthen the strength of the fire door body 1. The reinforcement groove 2, the heat dissipation groove 3 and the cavity on the serpentine reinforcement plate 7 are used to reduce the weight of the fire door. When a fire occurs, the outer side of the fire door body 1 is used for fire prevention. At the same time, the fireproof rock wool 9 in the serpentine reinforcement plate 7 can also be used for fire prevention again after the outer side of the fire door body 1 fails. In addition, the fire door body 1 is burned by flames and the heat is introduced into the heat dissipation fins 11 through the serpentine reinforcement plate 7. The thermal fins 11 introduce heat into the heat dissipation groove 3, and the serpentine reinforcement plate 7 introduces some heat to the push box 12. At this time, the heat heats the water in the water storage tank 14, and the water is heated to become water vapor and expands. Then, the water vapor in the water storage tank 14 drives the piston plate 13 to move in the push box 12, and the movement of the piston plate 13 drives the push column 17 to move. The movement of the push column 17 is used to push the outer sealing plate 6, so that the inner cavity of the heat dissipation groove 3 is connected with the outside through the heat dissipation port 5, and then the heat in the heat dissipation groove 3 is discharged, so as to achieve cooling and fire prevention of the fire door body 1.
