Background
The concrete protection layer is used for protecting the reinforcing steel bars in the building concrete structure, and the thickness and the quality of the concrete protection layer relate to the integral mechanical property and the fireproof and moistureproof performance of the reinforced concrete structure.
When fire disaster occurs in the building, the temperature of the concrete protection layer in the building is quickly raised under the action of flame, the strength of the conventional concrete begins to drop when the temperature reaches 300 ℃, the strength only remains 50% when the temperature reaches 500 ℃, and the strength of the concrete is almost completely lost when the temperature is higher than 800 ℃. Therefore, under the condition of fire, the concrete protective layer is easy to crack and fall off, so that the integral mechanical property of the reinforced concrete structure is rapidly reduced, and meanwhile, the strength of the exposed reinforcing steel bar is also rapidly reduced at the high temperature of flame.
Developers often spray fire-retardant coatings outside the concrete protective layer to improve the fire resistance of the building. The fireproof paint is coated on the surface of the structure and can form a layer with a certain thickness, and the propagation speed of the flame of the flammable base material can be reduced when a fire disaster occurs, so that the time for heating the concrete member to the material limit temperature is delayed, and the fire resistance limit of the concrete structure is greatly improved.
For the related technology, many chemical components in the fireproof paint can pollute the environment, and toxic substances are easy to generate after being heated, so that the fireproof paint is not beneficial to being used in the fireproof scheme of indoor roofs.

By adopting the scheme, along with the long-time boiling of water in the water tank layer, the water level in the water tank layer gradually drops, and the temperature of the area without water of the water tank layer is rapidly increased, so that the durability of the effect of the water tank layer is reduced. When the water level of the indoor water tank layer initially drops, water of the outdoor water tank layer is supplemented to the indoor water tank layer through the connecting pipe and the one-way valve. When the water levels of the two water tank layers are reduced to enable the floating ball of the floating ball valve to be in a low position, the floating ball valve is closed, water vapor generated by boiling gradually increases the air pressure in the water tank layer on one side of the room, the increased air pressure starts a trigger assembly through an air pressure pipe, and the trigger assembly controls the pressing assembly to press the water pressure of the water tank layer on one side of the room into the water tank layer on one side of the room; when the water level of the water tank layer at one side of the room is restored, the floating ball of the floating ball valve floats, the floating ball valve is opened, and the water tank layer at one side of the room continuously discharges water vapor from the exhaust pipe.

As the water in the water tank layer 4 boils for a long time, the water level in the water tank layer 4 gradually decreases, and the temperature of the area of the water tank layer 4 where no water is present increases rapidly, reducing the durability of the effect of the water tank layer 4. When the water level of the indoor side water tank layer 4 is primarily lowered, the water of the outdoor side water tank layer 4 is replenished to the indoor side water tank layer 4 through the connection pipe 41 and the check valve 411. When the water levels of the two water tank layers 4 drop to enable the floating ball of the floating ball valve 52 to be in a low position, the floating ball valve 52 is closed, the water vapor generated by boiling gradually increases the air pressure in the water tank layer 4 on one side of the room, the increased air pressure opens the trigger assembly 8 through the air pressure pipe 87, and the trigger assembly 8 controls the pressing assembly 7 to press the water pressure of the water tank layer 4 on one side of the room into the water tank layer 4 on one side of the room; when the water level of the water tank layer 4 at the indoor side is restored, the floating ball of the floating ball valve 52 floats, the floating ball valve 52 is opened, and the water tank layer 4 at the indoor side continuously discharges water vapor from the exhaust pipe 5.
