[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example
[0019] See attached Figure 1-3 As shown, a smoke and fireproof door comprises a door body 1, door pockets 3 are arranged on both sides of the door body 1, a door handle 2 is arranged on the door body 1, the door body 1 comprises a steel frame 11, the steel frame 11 is a rectangular structure with a hollow center, and an aluminum alloy grid frame 12 is connected to the rectangular structure by bolts, the grid of the aluminum alloy grid frame 12 is filled with sound insulation cotton, fireproof felt 13 is arranged on the inner and outer surfaces of the steel frame 11, a sealing plate 14 is arranged on the outer side of the fireproof felt 13, and the sealing plate 14 is coated with fireproof paint 15, two sealing strips 16 are arranged on the surface of the door body 1, an inner concave structure 5 is arranged on the inner side of the door pocket 3, and the inner concave structure 5 corresponds to the sealing strip 16, an open U-shaped structure is arranged on one side of the steel frame 1, and the U-shaped structure is filled with fireproof glue, and the sealing strip 16 is a rubber strip.
[0020] Working principle: The main part of the fire door adopts a steel frame 11 structure with a hollow center, and an aluminum alloy grid frame 12 connected by bolts is provided in the steel frame 11, which realizes the overall stability of the door, and sound insulation cotton is added in the aluminum alloy grid frame 12 to improve the overall sound insulation effect of the door. Fireproof felt 13 and fireproof paint 15 are provided on the outside of the steel frame to improve the overall fire resistance of the door. The steel frame 1 has a U-shaped structure with an open side, and the U-shaped structure is filled with fireproof glue. When encountering a fire and encountering high temperature, the fireproof glue will expand rapidly to block the gap between the doors and reduce the penetration of smoke. The cooperation between the concave structure 5 and the sealing strip 16 further improves the smoke-proof effect of the door.
[0021] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
