[0021] The utility model will be described in detail below by combining embodiments thereof with reference to the accompanying drawings. DETAILED DESCRIPTION

[0022] The utility model will be further described below by combining the accompanying drawings and embodiments thereof:

[0023] A fireproof early warning roof panel sequentially comprises a roof panel base 1, a fireproof and heat-insulating layer 3, a waterproof layer 4 and a concrete surface layer 5 from bottom to top, a signal combination part 2 is arranged between the roof panel base 1 and the fireproof and heat-insulating layer 3, the signal combination part 2 comprises temperature sensors 21 arranged at equal intervals and wires 22 connecting the sensors, the temperature sensors 21 are made of conductive ceramic and internally encapsulate conductive temperature phase change materials.​

[0024] The roof panel base layer 1 comprises a base plate 11 and connecting tenons 12 arranged at equal intervals on the upper part of the base plate 11, and is composed of a profiled steel plate and concrete poured on the bottom surface of the profiled steel plate, wherein the profiled steel plate is an integral panel penetrating through the base plate 11 and the top of the connecting tenons 12.

[0025] The fireproof and heat-insulating layer 3 comprises a heat-insulating plate 31 and connecting mortises 32 arranged at equal intervals on the bottom of the heat-insulating plate 31.

[0026] The connecting tenons 12 on the upper part of the roof panel base layer 1 are connected with the connecting mortises 32 on the lower part of the fireproof and heat-insulating layer 3 through mortise and tenon connection.

[0027] The signal combination 2 is arranged according to fireproof partitions, and the signal combination 2 of each fireproof partition is arranged at not less than two places, so that the fire source and the fire occurrence position can be accurately predicted.

[0028] The fireproof and heat-insulating layer 3 is composed of a rock wool board or a heat-insulating board and a rock wool isolation belt.

[0029] The waterproof layer 4 is a self-adhesive waterproof coiled material, and is constructed by using a cold paving method.

[0030] Working principle: under the condition that the temperature sensor 21 is electrified, when a fire or high temperature occurs, the solid-liquid form of the temperature phase change material encapsulated in the conductive ceramic changes, the temperature phase change material changes from a solid-liquid mixed state to a liquid state, the resistance value of the temperature sensor increases, the current flow through the wire increases, and then the external signal receiving end feedbacks. At the same time, when the external temperature of the fire warning roof panel is too high or too low, the temperature phase change material of the temperature sensor 21 can store and release heat through material phase change, so that the structure can adjust the indoor temperature, thereby reducing resource energy consumption. The fireproof effect under high temperature conditions is ideal, the signal combination 2 and related components can quickly respond to fire or high temperature, and fire alarm can be realized without relying on external warning systems.
