[0015] 3. Beneficial effects
[0016] Compared with the prior art, the advantages of the utility model are:
[0017] (1) The utility model provides a high-strength fire door. A grille mesh is fixed on a reinforcing plate. The grille mesh with a cross-rib structure can reinforce the reinforcing plate, thereby increasing the strength and rigidity of the fire door. The reinforcing plate is filled with wave peak sound-absorbing cotton, which can improve the sound insulation effect of the fire door.
[0018] (2) The utility model is a high-strength fireproof door. By filling the interior of the insulation board with melamine insulation and sound insulation cotton, the flexible, high-opening-pore sound insulation material made of melamine resin foam can play the role of heat insulation and sound insulation for the outer door panel, so that when a fire occurs, the outer door panel will not transfer heat to the other side of the fireproof door when the fire spreads.
[0019] (3) The utility model is a high-strength fire door. A fire door core panel is installed in the fire door. With the help of reinforcing blocks arranged and connected to each other on the fire door core panel, the strength and rigidity of the fire door core panel can be increased, so that the fire door can be provided with reinforcing support. Moreover, a regular hexagonal plate is connected inside each of two longitudinally spaced reinforcing blocks, and the regular hexagonal plate can increase the strength of the reinforcing blocks.
[0020] (4) The utility model provides a high-strength fire door, which contacts the reinforcing plate through a support member. When the fire door is hit, the support member is squeezed. The arc-shaped plate structure on the support member has good stability and bearing capacity, so the impact force of the collision can be absorbed. When the arc-shaped plate is subjected to force, it is pressed downward, driving the left and right push rods to move together and squeezing the spring damping at the bottom. The spring damping can buffer the downward pressure of the arc-shaped plate, making it difficult for the reinforcing plate to deform, thereby increasing the rigidity and strength of the fire door.

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] Example:
[0029] See also Figure 1-Figure 5A high-strength fire door, whose structure includes a door frame 1, a buffer 2 and a fire door 3. The buffer 2 is installed on the top of one side of the door frame 1. The door frame 1 is rotated by rotating a hinge to cooperate with the fire door 3 that can block the fire. The fire door 3 is connected to the buffer 2.
[0030] In this embodiment, the fire door 3 includes a fixed frame 31, a fire door core panel 32, a reinforcement panel 33, an insulation panel 34, an outer door panel 35 and a support member 36. The outer door panel 35 is installed on the fixed frame 31, and the fire door core panel 32, the reinforcement panel 33 and the insulation panel 34 are installed in sequence between the fixed frame 31 and the outer door panel 35. A plurality of support members 36 are arranged in an equidistant array on the fire door core panel 32, and the tops of the plurality of support members 36 are connected to the reinforcement panel 33 to support and buffer the reinforcement panel 33.
[0031] In this embodiment, the interior of the insulation board 34 is filled with melamine insulation and sound insulation cotton, which can provide thermal insulation and sound insulation for the outer door panel 35, so that when a fire occurs, the outer door panel 35 will not transfer heat to the other side of the fire door 3 when the fire spreads.
[0032] In this embodiment, a grille mesh 331 is fixed on the reinforcing plate 33. The grille mesh 331 is a cross rib that can reinforce the reinforcing plate 33. The interior of the reinforcing plate 33 is filled with wave peak sound-absorbing cotton, which can improve the sound insulation effect of the fire door 3.
[0033] In this embodiment, the fire door core panel 32 includes reinforcement blocks 321 that are densely distributed in the panel and connected to each other. Each longitudinally separated reinforcement block 321 is connected to a regular hexagonal plate 322. The regular hexagonal plate 322 can increase the strength of the reinforcement block 321, and a new small fire door core panel structure will be formed between each adjacent regular hexagonal plate 322 in the horizontal direction, thereby increasing the strength of the fire door core panel 32.
[0034] In this embodiment, the support member 36 includes a base plate 21, a support plate 22, an arc plate 23, a corrugated groove 24, a slide groove 25, a left push rod 26, a right push rod 27 and a spring damper 28. The support plates 22 are symmetrically installed on the base plate 21, and the arc plate 23 is connected between the two support plates 22. The bottom of the arc plate 23 is rotatably matched with the left push rod 26 and the right push rod 27 through a rotating seat. The right push rod 27 is located in the groove of the left push rod 26 and rotatably matched therewith. The bottoms of both sides of the left push rod 26 and the right push rod 27 are connected to the spring damper 28. A slide groove 25 is opened on the support plate 22. The left push rod 26 and the right push rod 27 are both slidably matched with the slide groove 25, and the spring damper 28 is located in the slide groove 25.
[0035] In this embodiment, the tops of the left push rod 26 and the right push rod 27 are provided with corrugated grooves 24 , which are in contact with the reinforcing plate 33 , thereby increasing the friction between the reinforcing plate 24 and making the support for the reinforcing plate 33 more stable.
[0036] Implementation principle: Placing the fire door core board 32, the reinforcement board 33 and the heat insulation board 34 inside the fixed frame 31 and the outer door board 35 can increase the overall strength and toughness of the fire door 3. The strength and rigidity of the fire door core board 32 can be increased by means of the interconnected reinforcement blocks 321 on the fire door core board 32, so that it can play a role in strengthening and supporting the fire door 3, and the grille mesh board 331 on the reinforcement board 33 can play a role in reinforcing the reinforcement board 33. The sound insulation effect of the fire door 3 can be improved by the wave peak sound-absorbing cotton filled inside the reinforcement board 33, and the heat insulation board 34 is a polystyrene foam board, which can play a role in heat insulation and sound insulation for the outer door board 35, so that when a fire occurs, the outer door board 35 will not transfer heat to the other side of the fire door 3 when the fire spreads;
[0037] When the outer door panel 35 of the fire door 3 is hit, it will squeeze the reinforcing plate 33 and the supporting member 36 in contact with it through the reinforcing plate 33. The arc structure of the arc plate 23 on the supporting member 36 has good stability and bearing capacity, so the impact force of the collision can be absorbed. When the arc plate 23 is subjected to force, it will press downward, driving the left push rod 26 and the right push rod 27 to move together and squeeze the spring damper 28 at the bottom. With the help of the spring damper 28, the downward pressure of the arc plate 23 is buffered, so that the reinforcing plate 33 is not easy to deform, thereby increasing the rigidity and strength of the fire door 3.
