[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The following describes an embodiment of the present invention based on its overall structure.

[0033] Example 1

[0034] A reinforced structural composite wooden door, such as Figure 1-4As shown, it includes a steel frame 1, one of the vertical sides of the steel frame 1 is fixedly connected to a frame 101. Specifically, the frame 101 is also made of steel and is connected to the steel frame 1 by welding. At least one connecting seat 102 is provided on the frame 101, and the connecting seat 102 is penetrated by a hole for installing a hinge. The remaining sides of the steel frame 1 are covered with wooden strips, and the wooden strips are used to decorate the composite wooden door. The front and back of the steel frame 1 are sequentially provided with steel plate layers 3 and wooden board layers 2 from the inside to the outside. The steel frame 1 is connected with a reinforcing rod 4 along the vertical interval between the two steel plate layers 3. Specifically, in this embodiment, the reinforcing rod 4 is also a steel square tube.

[0035] See also Figure 1-4 , the connecting seat 102 is used to connect the hinge, and four are arranged in the vertical direction. Multiple connecting seats 102 can stably connect the hinge to prevent the composite wooden door from being damaged at the hinge when it is impacted. The width of the frame 101 is equal to the sum of the thicknesses of the steel frame 1, the two wooden layers 2, and the two steel layer 3, to prevent the frame 101 from protruding from the front or back of the composite wooden door. The first vertical wooden strip 5, the second vertical wooden strip 6, the steel frame 1, the steel layer 3, and the wooden layer 2 are provided with a notch for installing the door lock in the middle of the steel frame 1 away from the frame 101. The door lock is installed from the notch, so that the door lock can further clamp and fix the composite wooden door on the front and back of the door. At the same time, since the door lock is installed through the steel frame 1, the installation firmness of the door lock can be effectively improved. Five reinforcing rods 4 are arranged in the vertical direction, and the reinforcing rods 4 at the top and bottom are close to the inner wall of the steel frame 1. The reinforcing rods 4 can effectively prevent the steel frame 1 from deformation.

[0036] See also Figure 2-4 The front edge of the steel frame 1 is vertically covered with a first vertical wooden strip 5 in the direction away from the frame 101, and is covered with a first horizontal wooden strip 7 at the top and bottom. The back edge of the steel frame 1 is vertically covered with a second vertical wooden strip 6 in the direction away from the frame 101, and is covered with a second horizontal wooden strip 8 at the top and bottom. The first vertical wooden strip 5 and the second vertical wooden strip 6 are connected to each other, and the first horizontal wooden strip 7 and the second horizontal wooden strip 8 of the same height are connected to each other. The wooden structure is covered at the edge of the steel frame 1 to maintain the original beauty of the composite wooden door. The sum of the thickness of the two steel plate layers 3 and the reinforcing rod 4 is equal to the thickness of the steel frame 1. The edge of the steel plate layer 3 is in contact with the inner wall of the steel frame 1. The two steel plate layers 3 are flush with the front and back of the steel frame 1, respectively, so that the wooden layer 2 can fit smoothly to avoid gaps at the edge of the composite wooden door.

[0037] Example 2

[0038] A reinforced structural composite wooden door, such as Figure 1-4As shown, based on Example 1, the difference from Example 1 is that a sealed and vacuum space is formed between the two steel plate layers 3, and the vacuum sealed environment is conducive to improving the sound insulation ability of the composite wooden door, and can further prevent the steel frame 1 and the reinforcing rod 4 and other structures from rusting. A mortise and tenon structure that fits together is provided between the first horizontal wooden strip 7 and the second horizontal wooden strip 8, and a mortise and tenon structure that fits together is also provided between the first vertical wooden strip 5 and the second vertical wooden strip 6, which effectively increases the stability of the fit between the first horizontal wooden strip 7 and the second horizontal wooden strip 8 and the first vertical wooden strip 5 and the second vertical wooden strip 6.

[0039] The working principle of the present invention is: a steel frame 1 is composited with a steel plate layer 3 and a wooden board layer 2, and wooden strips are covered at the edges. This can effectively improve the composite wooden door's ability to resist penetration and impact while ensuring its aesthetics. At the same time, since the hinge is directly connected to the frame 101 of the steel frame 1, the composite wooden door's impact resistance is further improved, preventing the composite wooden door from being damaged by impact at the hinge.
