Description

Technical Field

[0001] The utility model relates to the technical field of fireproof doors, in particular to an inorganic foamed composite fireproof door core board with a reinforcement layer. Background Art

[0002] Nowadays, many public places and workshops require the use of steel fire doors. Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. They are composed of fireproof accessories such as door frames, door leaves, and filling materials. In addition to the functions of ordinary doors, fire doors can also prevent the spread of fire and smoke.

[0003] After searching, the existing Chinese patent announcement number is: CN211115589U, which provides a fire door core plate structure. The patent fixes the discharge box in the trough by setting a cover in the trough. When the cover is melted by the fire, the discharge box will pop out under the elastic action of the spring. After the discharge box melts, the dry powder fire extinguishing agent inside it will be released to put out the fire, thereby controlling the spread of the fire. This solves the problem that the fire door core plate will still be damaged if it is burned for a long time and has no effect on controlling the spread of the fire.

[0004] Although the above patent can block the fire, the above fire door core board still has the following problems: the fire door core board structure is not strong enough in actual use, and the effect of resisting external impact is not good. The filling material in the general fire door is integrally formed and filled in the door leaf, so that the door panels on both sides of the door leaf have a certain distance, which makes the two sides of the door leaf easy to deform. In addition, the filling material in the fire door has poor impact resistance compared with the door leaf.

[0005] In view of the above problems, an inorganic foamed composite fireproof door core panel with a reinforcement layer is proposed. Utility Model Content
