[0006] A fireproof door core panel with a heat-insulating function comprises a foamed cement board and an outer panel, wherein a first embedded panel and a second embedded panel are respectively embedded and installed on the front and back sides of the foamed cement board, and the outer panel is glued and fixed to the first embedded panel and the second embedded panel, wherein the first embedded panel and the second embedded panel correspond in position and are the same in number, a first nail is fixedly installed on the upper and lower parts of the first embedded panel, and a second nail is symmetrically fixedly installed on the middle part of the second embedded panel, and the first nail and the second nail are staggered and nailed into the foamed cement board.
[0007] As a further description of the above technical solution:
[0008] The first embedded plate and the second embedded plate are arranged at the corners, sides or center of the foamed cement board.
[0009] As a further description of the above technical solution:
[0010] The first embedded plate and the second embedded plate are diamond-shaped.
[0011] As a further description of the above technical solution:
[0012] The first embedded plate and the second embedded plate are steel plates.
[0013] As a further description of the above technical solution:
[0014] The first nail and the second nail are set to be of equal length.
[0015] As a further description of the above technical solution:
[0016] The lengths of the first nail and the second nail are between two-thirds and three-quarters of the thickness of the foamed cement board.
[0017] Compared with the prior art, the present invention provides a fireproof door core board with heat insulation function, which has the following beneficial effects:
[0018] 1. In the present invention, a first embedded panel and a second embedded panel are fixedly mounted on the foamed cement panel, and the outer panel is fixedly mounted using the first and second embedded panels. This allows the outer surface of the foamed cement panel to be fixedly assembled with outer panels of various materials without the need for coating. This not only reduces the overall cost of the fire door core panel but also allows for a wide variety of combinations.
[0019] 2. In the present invention, the first and second nails are designed on the first embedded plate and the second embedded plate. The first and second nails are staggered so that they can be nailed deep without affecting each other, so that the first and second embedded plates are firmly fixed. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] 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. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] Example:
[0028] See also Figures 1-4The utility model provides a fireproof door core panel with heat insulation function, including a foamed cement board 1 and an outer board 2. The front and back sides of the foamed cement board 1 are respectively embedded with a first embedded board 3 and a second embedded board 4. The outer board 2 is glued and fixed to the first embedded board 3 and the second embedded board 4. The first embedded board 3 and the second embedded board 4 correspond in position and are the same in number. The upper and lower parts of the first embedded board 3 are fixed with a first nail 5, and the middle part of the second embedded board 4 is symmetrically fixed with a second nail 6. The first nail 5 and the second nail 6 are staggered and nailed into the foamed cement board 1.
