Heat-resistant and fireproof building fire-fighting floor slab

Abstract

The invention discloses a heat-resistant and fireproof building fire-fighting floor slab, and belongs to the technical field of floor slab fireproofing. A plurality of sets of refrigeration flame-retardant bodies are installed between an inner heat insulation layer and an outer fireproof layer, and each refrigeration flame-retardant body is composed of a plurality of refrigeration balls and water cooling pipes which are distributed in a staggered mode. When a huge fire happens by accident, temperature sensing heat conductors connected with the outer ends of the refrigeration balls sense the external high-temperature environment, the multiple temperature sensing heat conductors conduct the high temperature inwards in a multi-point mode, and therefore the multiple refrigeration balls at the inner ends sense the high temperature, a hot melting refrigeration mixture on the inner sides of the refrigeration balls overflows ammonium chloride and barium hydroxide octahydrate due to high-temperature hot melting, and after the ammonium chloride and the barium hydroxide octahydrate are mixed, the environment absorbs the heat and is cooled, meanwhile, the low temperature is transmitted to the water cooling pipes on one side, so that the temperature of water cooling liquid in the water cooling pipes is suddenly reduced, a flame-retardant layer formed by the inner heat insulation layer and the outer fireproof layer has a good flame-retardant effect, the fireproof performance of an outer decoration plate located on the outer side is better facilitated, and fireproof and flame-retardant measures are more subjectively taken.

AI Technical Summary

Benefits of technology

This patented describes different ways for improving the performance of fire resistant coatings used in buildings during fires or explosion hazards. These techniques involve adding specific chemical substances like aluminum hydride (AlH3), boron nitrogen compounds, metal oxides, silica gel, ceramic microspheres, etc., along with various types of fire excluding agents such as halogenated ethylene gases, oxygen free radical generators, pyrotechnics, pigments, and color changing dyes. By incorporating these components within the fire prevention system, they can improve its efficiency and safety against combustible objects fired through doors without causing damage.

Problems solved by technology

Technological Problem: Current solutions involve installing extra equipment around areas with poor fire resistance such as highways or tunnel walls which may lead to rapid fires caused by unintended actions like water damage or other factors affecting their functioning. Existing thermal insulation systems have limitations due to lack of sufficient strength against these types of events without causing excessive weight or cost overruns during installation.
