Decorative ceiling with fire-resistant function

Abstract

The invention relates to a decorative ceiling with a fire-resistant function. The decorative ceiling comprises a keel skeleton and a ceiling plate, and the keel skeleton is provided with a mounting opening; the inner walls of the two opposite sides of the mounting opening are provided with hooks, and the two opposite side walls of the ceiling plate are provided with hanging rods correspondingly, wherein the hanging rods can be hung on the corresponding hooks; cavities are formed in the hanging rods in the length direction of the hanging rods, and are filled with a fire extinguishing agent; thehanging rods are made of a material which is solid at a room temperature and is melted at a high temperature; and the upper end of the keel skeleton is provided with a suspension-hanging device whichis used for making the ceiling plate not completely fall off from the keel skeleton. When a fire occurs in a room, the hanging rods are melted under the influence of thee high temperature, and separated from the hooks, so that the side of the ceiling plate is overturned downwards, the fire extinguishing agent inside the hanging rods is poured out from a gap passingly to inhibit spread of a flame,dense smoke generated by combustion can enter the upper part of the keel skeleton from the opened mounting opening, so that the spread of the indoor dense smoke is delayed, and evacuation safety of indoor persons is improved.

Description

technical field [0001] The invention relates to the technical field of decorative suspended ceilings, in particular to a decorative suspended ceiling with a fireproof function. Background technique [0002] Suspended ceiling refers to the top decoration of the living environment of the house. Simply put, it refers to the decoration of the ceiling.

Problems solved by technology

[0004] The above existing technical solutions have the following defects: although the magnesium crystal plate has the function of fire prevention, it does not have the effect of suppressing the fire. If the fire cannot be controlled, other structures of the suspended ceiling will be under the high temperature of the flame for a long time, and the suspended ceiling will still be damaged destroyed, resulting in more property damage and even affecting the safe evacuation of residents
