In the installation window; the door panel includes a layer of sound insulation board, two layers of sound insulation cotton and two layers of door panels, the sound insulation cotton is attached to both sides of the sound insulation board, and the door panel covers the surface of the sound insulation cotton, so The door panel is formed by laminating a first plate, a second plate and a third plate, and each plate is provided with a flame retardant layer by spraying or soaking.

As a preferred solution, the third plate is provided with a recess, and after the door panel is covered on the surface of the sound insulation cotton, the sound insulation cotton is located in the recess.

As a preferred solution, two door frames are arranged symmetrically on the left and right, and a stopper is provided at the adjacent ends of the left and right door frames.

As a preferred solution, the adjacent surfaces of the left and right door frames are provided with a limiting concave portion and a limiting convex portion that can limit the position of each other.

As a preferred solution: rubber strips are provided between the two door frames and between the door frame and the fixed frame.

As a preferred solution: the top of the door frame is provided with a door header, and the door header is arranged in a semicircular structure.

Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solutions that the door panel is directly covered on the sound insulation cotton by the sound insulation board and the sound insulation cotton, which can effectively solve the problem of fire prevention in the past. The door has the problem of poor sound insulation; at the same time, the first plate, the second plate and the third plate are laminated and each plate is provided with a door panel with a flame retardant layer, which can form multiple fireproof effects, which can further improve the safety of the fire door. Fire resistance.
