After inserting the steel plate 402 along the embedding groove 401 on the right side of the door body 1, the left end of the steel plate 402 is fixed at the notch of the embedding groove 401 by using the embedding plate 406 connected to the steel plate 402 and combining with the fixing bolt 405. This structure can greatly enhance the strength of the wooden door by combining the wooden structure of the door body 1 with the steel plate 402 structure. And the steel plate 402 adopts a hollow structure with through holes 403 and the strengthening columns 404 inside it, which can ensure the strength of the steel plate 402 and also reduce the weight of the entire door body 1 to a certain extent, facilitating the transportation and installation of the wooden door. During the assembly process of the wooden door, glue needs to be applied to the entire connection surface between the steel plate 402 and the embedding plate 406, which can ensure the fit and installation stability between the steel plate 402 and the embedding groove 401 of the door body 1.

[0027] Reference Figure 2 and Figure 5 , the middle part of the strengthening column 404 is cylindrical, and the two ends of the strengthening column 404 are frustum-shaped.

This structure can greatly improve the strength of the wooden door by combining the wooden structure of the door body 1 and the steel plate 402 structure. Moreover, the steel plate 402 adopts a hollow structure with through holes 403 and the reinforcing columns 404 inside, which can ensure the strength of the steel plate 402. At the same time, to a certain extent, it also reduces the weight of the entire door body 1, facilitating the transportation and installation of the wooden door;

[0035] During use, the waterproof, moisture-proof and mildew-proof performance of the wooden door can be improved through the nano-silica coating 302. The natural wood wax layer 304 can protect the paint surface while being waterproof, moisture-proof, mildew-proof and insect-proof, and has a polishing effect. In addition, the synthetic resin primer layer 301 can resist the erosion of chemical substances such as acids, alkalis and organic solvents, ensuring the stability of the paint surface base. The polyurea anti-corrosion topcoat layer 303 has good tensile strength and does not show phenomena such as bubbles, bulges and peeling. By sequentially arranging the heat insulation plate layer 201 on the outer side of the door body 1, the heat insulation and high-temperature protection of the door body 1 are improved. Through the flame retardant plate layer 202 on the outer side of the heat insulation plate layer 201, the fire protection ability of the door body 1 can be improved.
