[0037] EMBODIMENT

[0038] Please refer to Figures 1-9 As shown in the drawings, the technical scheme of the integrally formed door leaf and fireproof door provided by the present application is: an integrally formed door leaf, comprising a door leaf frame 1, the inner side of the door leaf frame 1 is designed with a filling area 2, in this area, an autoclaved aerated concrete block 3 is filled inside, the autoclaved aerated concrete block 3 is tightly combined with the door leaf frame 1 to form an integrated structure, a reinforcing member 4 is designed inside the autoclaved aerated concrete block 3, which further improves the overall structural strength of the door leaf and ensures the stability and durability of the door leaf.

[0039] The mass ratio of autoclaved aerated concrete blocks 3 inside the door leaf is more than 95%, and the volume ratio is more than 99%. The high proportion of autoclaved aerated concrete filling not only significantly enhances the fireproof performance of the door leaf, but also effectively reduces the overall weight and improves the sound insulation effect. This design makes the door leaf provide excellent fire protection while maintaining lightness and ease of use, greatly improving its practicality and user experience in actual application.

[0040] The reinforcing member 4 includes a plurality of tie steel bars 401, a first steel bar 402 and a second steel bar 403. The tie steel bars 401 are uniformly distributed along the length and width directions of the door leaf frame 1. The first steel bar 402 and the second steel bar 403 are arranged at a predetermined angle between the tie steel bars 401 and are connected with the tie steel bars 401, forming an interlaced steel bar network structure. This steel bar network structure effectively enhances the overall structural strength of the door leaf, ensuring higher stability and durability when the door leaf is subjected to external forces. Specifically, the arrangement direction of the first steel bar 402 and the second steel bar 403 is not limited.

[0041] In this embodiment, the first steel bar 402 and the second steel bar 403 are arranged in the longitudinal and transverse directions on the inner side of the door leaf frame 1. In this design, the transverse and longitudinal steel bars work together to improve the tensile and compressive capacity of the door leaf under bending load. The longitudinal steel bar mainly bears tension, and the transverse steel bar helps to share bending moment.

[0042] The center point of the length direction of the tie steel bar 401 is aligned with the center point of the thickness of the door leaf frame 1, and the two ends of the first steel bar 402 are connected with the center point of the length direction of the tie steel bar 401. The design aims to place the longitudinal steel bar 402, which mainly bears tension, closer to the inside of the autoclaved aerated concrete block 3, thereby further improving the overall structural strength and stress performance of the door leaf. This layout not only optimizes the stress distribution of the steel bars, but also ensures the stability and durability of the door leaf during long-term use.

[0043] The opening of the door leaf frame 1 is designed with a bent part 5. The design of the bent part 5 aims to provide a flat and stable welding surface for the welding position of the tie steel bar 401, thereby significantly enhancing the connection between the door leaf frame 1 and the tie steel bar 401. In addition, the bent part 5 further fixes the autoclaved aerated concrete block 3 to some extent, effectively improving the overall structural stability and durability of the door leaf.

[0044] The door leaf frame 1 is also provided with reinforcing steel bars 6 at the four corners inside the door leaf frame 1 and at the midpoint of the second steel bar 403. The design aims to prevent the door leaf frame 1 from deforming under stress, and in addition, the reinforcing steel bars 6 further fix the autoclaved aerated concrete block 3 by cooperating with the tie steel bars 401, ensuring the stability of the door leaf when subjected to external forces.

[0045] The surfaces of the tie steel bars 401, the first steel bars 402 and the second steel bars 403 are all coated with anticorrosive agents. The main purpose of the anticorrosive treatment is to effectively block corrosive media such as moisture, oxygen, carbon dioxide and chloride ions by forming a protective film on the surface of the steel bars, thereby preventing the steel bars from rusting and deteriorating in the concrete environment. The coating of the anticorrosive agents not only significantly prolongs the service life of the steel bars, maintains the overall strength and stability of the structure, but also reduces the maintenance and repair costs required due to corrosion of the steel bars. In addition, the anticorrosive treatment improves the durability and reliability of the door leaf in various humid and corrosive environments, ensuring the safety and functionality of the door leaf in long-term use.

[0046] In addition, the utility model provides a fireproof door, including door frame 7, the side of door frame 7 with door leaf frame 1 is connected through setting fireproof hinge 8, and door frame 7 and door leaf frame 1 top are connected through setting fireproof closer 9, and this fireproof door includes integrally formed door leaf of any one described above.

[0047] The connecting part of door leaf frame 1 and fireproof hinge 8 and the connecting part of fireproof closer 9 are all designed with reinforcing lining plate 10. The design of reinforcing lining plate 10 aims to provide higher connecting strength between door leaf frame 1 and fireproof hinge 8 and fireproof closer 9, prevents the deformation of door leaf frame 1 when being stressed, and ensures that the fireproof door maintains high stability and reliability in the long-term use process.

[0048] The manufacturing method of the fireproof door is as follows:

[0049] Firstly, according to the outer shape size of the door leaf, the door frame 7 is manufactured, and the reinforcing lining plate 10 is welded on the door frame 7 for installing the hinge and the closer. Then, the steel bar structure part (i.e. the first steel bar 402 and the second steel bar 403) is manufactured according to the design requirements, and is placed in the door leaf frame 1, and then the door leaf frame 1 is closed on all sides. The tie steel bar 401 is welded on the inner side of the metal outer frame, and the steel bar structure part is welded to the appropriate position of the tie steel bar 401, and after completion, all the steel bars are subjected to anticorrosive treatment to form a stable steel bar framework.

[0050] Subsequently, the mortar is prepared and mixed, the mold is formed by placing the bottom support at the bottom of the door leaf frame 1, and the mixed mortar is poured into the assembled mold. The vibrator is used to arrange the bubbles of the mortar to ensure the compactness and uniformity of the concrete. Then, the poured mold is sent to the static curing chamber for gas generation and static curing, and the temperature and time are controlled to ensure the sufficient solidification and strength improvement of the autoclaved aerated concrete block.

[0051] After the gas generating static maintenance is completed, the mold is taken out and the excess blank is cut off by using a steel wire, the surface of the door leaf is cleaned to ensure that it is smooth and flat.

[0052] After the steam curing is completed, the bottom support is removed to obtain an integrally formed door leaf.
